It is one of the rare and intriguing combinatorial problems that lie in NP∩co-NP, but are not known to be in P. The existence of polynomial-time algorithms has been a major open problem for decades and apart from pseudopolynomial algorithms there is no algorithm that solves any non-trivial subclass in polynomial time. In this paper, we give several results based on the weight structures of the graph. First, we identify a notion of penalty and present a polynomial-time algorithm when the penalty is large. Our algorithm is the first polynomial-time algorithm on a large class of weighted graphs. It includes several worst-case instances on which previous algorithms, such as value iteration and random facet algorithms, require at least sub-exponential time. Our main technique is developing the first non-trivial approximation algorithm and showing how to convert it to an exact algorithm. Moreover, we show that in a practical case in verification where weights are clustered around a constant number of values, the energy game problem can be solved in polynomial time. We also show that the problem is still as hard as in general when the clique-width is bounded or the graph is strongly ergodic, suggesting that restricting the graph structure does not necessarily help.","lang":"eng"}],"status":"public","external_id":{"arxiv":["1604.08234"],"isi":["000340552300005"]},"publist_id":"7282","oa_version":"Preprint","date_created":"2018-12-11T11:47:01Z","scopus_import":"1","publication":"Algorithmica","type":"journal_article","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1604.08234"}]},{"article_processing_charge":"No","title":"Extensional crisis and proving identity","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"ToHe"}],"day":"01","das_tickbox":"1","_id":"1872","quality_controlled":"1","date_published":"2014-01-01T00:00:00Z","conference":{"name":"ATVA: Automated Technology for Verification and Analysis","start_date":"2014-11-03","location":"Sydney, Australia","end_date":"2014-11-07"},"publisher":"Springer","doi":"10.1007/978-3-319-11936-6_14","file":[{"relation":"main_file","creator":"system","access_level":"open_access","date_created":"2018-12-12T10:10:15Z","content_type":"application/pdf","file_size":244294,"checksum":"af4bd3fc1f4c93075e4dc5cbf625fe7b","date_updated":"2020-07-14T12:45:19Z","file_id":"4801","file_name":"IST-2016-641-v1+1_atva2014.pdf"}],"acknowledgement":"This research was supported in part by the Austrian National Research Network RiSE (S11410-N23).","author":[{"full_name":"Gupta, Ashutosh","id":"335E5684-F248-11E8-B48F-1D18A9856A87","last_name":"Gupta","first_name":"Ashutosh"},{"full_name":"Kovács, Laura","first_name":"Laura","last_name":"Kovács"},{"full_name":"Kragl, Bernhard","id":"320FC952-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7745-9117","first_name":"Bernhard","last_name":"Kragl"},{"last_name":"Voronkov","first_name":"Andrei","full_name":"Voronkov, Andrei"}],"alternative_title":["LNCS"],"page":"185 - 200","publication_status":"published","file_date_updated":"2020-07-14T12:45:19Z","year":"2014","month":"01","volume":8837,"has_accepted_license":"1","status":"public","abstract":[{"text":"Extensionality axioms are common when reasoning about data collections, such as arrays and functions in program analysis, or sets in mathematics. An extensionality axiom asserts that two collections are equal if they consist of the same elements at the same indices. Using extensionality is often required to show that two collections are equal. A typical example is the set theory theorem (∀x)(∀y)x∪y = y ∪x. Interestingly, while humans have no problem with proving such set identities using extensionality, they are very hard for superposition theorem provers because of the calculi they use. In this paper we show how addition of a new inference rule, called extensionality resolution, allows first-order theorem provers to easily solve problems no modern first-order theorem prover can solve. We illustrate this by running the VAMPIRE theorem prover with extensionality resolution on a number of set theory and array problems. Extensionality resolution helps VAMPIRE to solve problems from the TPTP library of first-order problems that were never solved before by any prover.","lang":"eng"}],"type":"conference","publist_id":"5226","scopus_import":"1","date_created":"2018-12-11T11:54:28Z","publication":"12th International Symposium on Automated Technology for Verification and Analysis","oa_version":"Submitted Version","language":[{"iso":"eng"}],"citation":{"chicago":"Gupta, Ashutosh, Laura Kovács, Bernhard Kragl, and Andrei Voronkov. “Extensional Crisis and Proving Identity.” In <i>12th International Symposium on Automated Technology for Verification and Analysis</i>, 8837:185–200.

We here test whether the presence of a pupal cocoon, which occurs in some ant species but not in others, affects the sanitary brood care and fungal infection patterns after exposure to the entomopathogenic fungus Metarhizium brunneum. We use a) a comparative approach analysing four species with either naked or cocooned pupae and b) a within-species analysis of a single ant species, in which both pupal types co-exist in the same colony. Results: We found that the presence of a cocoon did not compromise fungal pathogen detection by the ants and that species with cocooned pupae increased brood grooming after pathogen exposure. All tested ant species further removed brood from their nests, which was predominantly expressed towards larvae and naked pupae treated with the live fungal pathogen. In contrast, cocooned pupae exposed to live fungus were not removed at higher rates than cocooned pupae exposed to dead fungus or a sham control. Consistent with this, exposure to the live fungus caused high numbers of infections and fungal outgrowth in larvae and naked pupae, but not in cocooned pupae. Moreover, the ants consistently removed the brood prior to fungal outgrowth, ensuring a clean brood chamber. Conclusion: Our study suggests that the pupal cocoon has a protective effect against fungal infection, causing an adaptive change in sanitary behaviours by the ants. It further demonstrates that brood removal - originally described for honeybees as “hygienic behaviour” – is a widespread sanitary behaviour in ants, which likely has important implications on disease dynamics in social insect colonies."}],"type":"research_data_reference","main_file_link":[{"open_access":"1","url":"https://doi.org/10.5061/dryad.nc0gc"}],"date_created":"2021-07-30T08:24:11Z","oa_version":"Published Version","publisher":"Dryad","doi":"10.5061/dryad.nc0gc","date_updated":"2026-07-28T09:35:11Z"},{"file":[{"creator":"system","relation":"main_file","access_level":"open_access","content_type":"application/pdf","date_created":"2018-12-12T10:13:43Z","file_size":825756,"checksum":"2c121b5e884992dfec5605bdf4e659da","file_id":"5029","file_name":"IST-2016-417-v1+1_J._Virol.-2014-Kuchibhatla-10-20.pdf","date_updated":"2020-07-14T12:45:34Z"}],"isi":1,"doi":"10.1128/JVI.02595-13","publisher":"ASM","das_tickbox":"1","_id":"2250","date_published":"2014-01-01T00:00:00Z","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"title":"Powerful sequence similarity search methods and in-depth manual analyses can identify remote homologs in many apparently \"orphan\" viral proteins","day":"01","department":[{"_id":"MD"}],"article_processing_charge":"No","publication_identifier":{"issn":["0022-538X"]},"tmp":{"name":"Creative Commons Attribution 3.0 Unported (CC BY 3.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/3.0/legalcode","short":"CC BY (3.0)"},"intvolume":"        88","date_updated":"2026-07-28T10:18:04Z","ddc":["570"],"pubrep_id":"417","scopus_import":"1","oa_version":"Published Version","publist_id":"4698","date_created":"2018-12-11T11:56:34Z","publication":"Journal of Virology","type":"journal_article","abstract":[{"text":"The genome sequences of new viruses often contain many &quot;orphan&quot; or &quot;taxon-specific&quot; proteins apparently lacking homologs. However, because viral proteins evolve very fast, commonly used sequence similarity detection methods such as BLAST may overlook homologs. We analyzed a data set of proteins from RNA viruses characterized as &quot;genus specific&quot; by BLAST. More powerful methods developed recently, such as HHblits or HHpred (available through web-based, user-friendly interfaces), could detect distant homologs of a quarter of these proteins, suggesting that these methods should be used to annotate viral genomes. In-depth manual analyses of a subset of the remaining sequences, guided by contextual information such as taxonomy, gene order, or domain cooccurrence, identified distant homologs of another third. Thus, a combination of powerful automated methods and manual analyses can uncover distant homologs of many proteins thought to be orphans. We expect these methodological results to be also applicable to cellular organisms, since they generally evolve much more slowly than RNA viruses. As an application, we reanalyzed the genome of a bee pathogen, Chronic bee paralysis virus (CBPV). We could identify homologs of most of its proteins thought to be orphans; in each case, identifying homologs provided functional clues. We discovered that CBPV encodes a domain homologous to the Alphavirus methyltransferase-guanylyltransferase; a putative membrane protein, SP24, with homologs in unrelated insect viruses and insect-transmitted plant viruses having different morphologies (cileviruses, higreviruses, blunerviruses, negeviruses); and a putative virion glycoprotein, ORF2, also found in negeviruses.

While in general, the winning strategies in such games may require infinite memory, for synthesis the most relevant problem is the construction of a finite-memory winning strategy (if one exists). Our main contributions are as follows. First, we show a tight exponential bound (matching upper and lower bounds) on the memory required for finite-memory winning strategies in both multi-dimensional mean-payoff and energy games along with parity objectives. This significantly improves the triple exponential upper bound for multi energy games (without parity) that could be derived from results in literature for games on vector addition systems with states. Second, we present an optimal symbolic and incremental algorithm to compute a finite-memory winning strategy (if one exists) in such games.

The first two chapters of this thesis address the phenomenon of 'social immunisation'. Social immunisation, that is the immunological protection of group members due to social contact to a pathogen-exposed nestmate, has been described in various social insect species against different types of pathogens. However, in the case of entomopathogenic fungi it has, so far, only been demonstrated that social immunisation exists at all. Its underlying mechanisms r any other properties were, however, unknown. In the first chapter of this thesis I identified the mechanistic basis of social immunisation in L. neglectus against the entomopathogenous fungus Metarhizium. I could show that nestmates of a pathogen-exposed individual contract low-level infections due to social interactions. These low-level infections are, however, non-lethal and cause an active stimulation of the immune system, which protects the nestmates upon subsequent pathogen encounters. In the second chapter of this thesis I investigated the specificity and colony level effects of social immunisation. I demonstrated that the protection conferred by social immunisation is highly specific, protecting ants only against the same pathogen strain. In addition, depending on the respective context, social immunisation may even cause fitness costs. I further showed that social immunisation crucially affects sanitary behaviour and disease dynamics within ant groups. In the third chapter of this thesis I studied the effects of the ectosymbiotic fungus Laboulbenia formicarum on its host L. neglectus. Although Laboulbeniales are the largest order of insect-parasitic fungi, research concerning host fitness consequence is sparse. I showed that highly Laboulbenia-infected ants sustain fitness costs under resource limitation, however, gain fitness benefits when exposed to an entomopathogenus fungus. These effects are probably cause by a prophylactic upregulation of behavioural as well as physiological immune defences in highly infected ants."}],"type":"dissertation","corr_author":"1","publist_id":"5814","oa_version":"None","date_created":"2018-12-11T11:51:46Z","month":"02","department":[{"_id":"SyCr"},{"_id":"GradSch"}],"day":"01","title":"Immune defences in ants: Effects of social immunisation and a fungal ectosymbiont in the ant Lasius neglectus","publication_status":"published","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","year":"2014","page":"131","publication_identifier":{"issn":["2663-337X"]},"article_processing_charge":"No","author":[{"full_name":"Konrad, Matthias","id":"46528076-F248-11E8-B48F-1D18A9856A87","last_name":"Konrad","first_name":"Matthias"}],"alternative_title":["ISTA Thesis"]},{"author":[{"full_name":"Stock, Miriam","id":"42462816-F248-11E8-B48F-1D18A9856A87","first_name":"Miriam","last_name":"Stock"}],"alternative_title":["ISTA Thesis"],"publication_identifier":{"issn":["2663-337X"]},"page":"101","article_processing_charge":"No","publication_status":"published","title":"Evolution of a fungal pathogen towards individual versus social immunity in ants","year":"2014","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","month":"04","department":[{"_id":"SyCr"},{"_id":"GradSch"}],"day":"01","abstract":[{"lang":"eng","text":"The co-evolution of hosts and pathogens is characterized by continuous adaptations of both parties. Pathogens of social insects need to adapt towards disease defences at two levels: 1) individual immunity of each colony member consisting of behavioural defence strategies as well as humoral and cellular immune responses and 2) social immunity that is collectively performed by all group members comprising behavioural, physiological and organisational defence strategies.\r\n\r\nTo disentangle the selection pressure on pathogens by the collective versus individual level of disease defence in social insects, we performed an evolution experiment using the Argentine Ant, Linepithema humile, as a host and a mixture of the general insect pathogenic fungus Metarhizium spp. (6 strains) as a pathogen. We allowed pathogen evolution over 10 serial host passages to two different evolution host treatments: (1) only individual host immunity in a single host treatment, and (2) simultaneously acting individual and social immunity in a social host treatment, in which an exposed ant was accompanied by two untreated nestmates.\r\n\r\nBefore starting the pathogen evolution experiment, the 6 Metarhizium spp. strains were characterised concerning conidiospore size killing rates in singly and socially reared ants, their competitiveness under coinfecting conditions and their influence on ant behaviour. We analysed how the ancestral atrain mixture changed in conidiospere size, killing rate and strain composition dependent on host treatment (single or social hosts) during 10 passages and found that killing rate and conidiospere size of the pathogen increased under both evolution regimes, but different depending on host treatment.\r\n\r\nTesting the evolved strain mixtures that evolved under either the single or social host treatment under both single and social current rearing conditions in a full factorial design experiment revealed that the additional collective defences in insect societies add new selection pressure for their coevolving pathogens that compromise their ability to adapt to its host at the group level. To our knowledge, this is the first study directly measuring the influence of social immunity on pathogen evolution."}],"status":"public","supervisor":[{"id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","full_name":"Cremer, Sylvia M","first_name":"Sylvia M","orcid":"0000-0002-2193-3868","last_name":"Cremer"}],"date_created":"2018-12-11T11:51:49Z","oa_version":"None","publist_id":"5803","type":"dissertation","corr_author":"1","citation":{"ista":"Stock M. 2014.

The reversible phosphorylation of PPIs on the 3, 4, or 5 position of inositol is performed by a set of organelle-specific kinases and phosphatases, and the characteristic head groups make these molecules ideal for regulating biological processes in time and space. In yeast and mammals, Ptdlns3P and Ptdlns(3,5)P2 play crucial roles in trafficking toward the lytic compartments, whereas the role in plants is not yet fully understood. Here we identified the role of a land plant-specific subgroup of PPI phosphatases, the suppressor of actin 2 (SAC2) to SAC5, during vauolar trafficking and morphogenesis in Arabidopsis thaliana. SAC2-SAC5 localize to the tonoplast along with Ptdlns3P, the presumable product of their activity. in SAC gain- and loss-of-function mutants, the levels of Ptdlns monophosphates and bisphosphates were changed, with opposite effects on the morphology of storage and lytic vacuoles, and the trafficking toward the vacuoles was defective. Moreover, multiple sac knockout mutants had an increased number of smaller storage and lytic vacuoles, whereas extralarge vacuoles were observed in the overexpression lines, correlating with various growth and developmental defects. The fragmented vacuolar phenotype of sac mutants could be mimicked by treating wild-type seedlings with Ptdlns(3,5)P2, corroborating that this PPI is important for vacuole morphology. Taken together, these results provide evidence that PPIs, together with their metabolic enzymes SAC2-SAC5, are crucial for vacuolar trafficking and for vacuolar morphology and function in plants.","lang":"eng"}],"supervisor":[{"full_name":"Friml, Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87","last_name":"Friml","orcid":"0000-0002-8302-7596","first_name":"Jiří"}],"status":"public","date_published":"2014-12-01T00:00:00Z","_id":"1402","citation":{"chicago":"Marhavá, Petra. “Molecular Mechanisms of Patterning and Subcellular Trafficking in Arabidopsis Thaliana.” Institute of Science and Technology Austria, 2014.","apa":"Marhavá, P.

In order to gain insight into the biophysical mechanism(s) underlying the tissue morphogenesis we studied the spreading of an epithelium during the early development of the zebrafish embryo. In zebrafish epiboly the enveloping cell layer (EVL), a simple squamous epithelium, spreads over the yolk cell to completely engulf it at the end of gastrulation. Previous studies have proposed that an actomyosin ring forming within the yolk syncytial layer (YSL) acts as purse string that through constriction along its circumference pulls on the margin of the EVL. Direct biophysical evidence for this hypothesis has however been missing. The aim of the thesis was to understand how the actomyosin ring may generate pulling forces onto the EVL and what cellular mechanism(s) may facilitate the spreading of the epithelium. Using laser ablation to measure cortical tension within the actomyosin ring we found an anisotropic tension distribution, which was highest along the circumference of the ring. However the low degree of anisotropy was incompatible with the actomyosin ring functioning as a purse string only. Additionally, we observed retrograde cortical flow from vegetal parts of the ring into the EVL margin. Interpreting the experimental data using a theoretical distribution that models  the tissues as active viscous gels led us to proposen that the actomyosin ring has a twofold contribution to EVL epiboly. It not only acts as a purse string through constriction along its circumference, but in addition constriction along the width of the ring generates pulling forces through friction-resisted cortical flow. Moreover, when rendering the purse string mechanism unproductive EVL epiboly proceeded normally indicating that the flow-friction mechanism is sufficient to drive the process. Aiming to understand what cellular mechanism(s) may facilitate the spreading of the epithelium we found that tension-oriented EVL cell divisions limit tissue anisotropy by releasing tension along the division axis and promote epithelial spreading. Notably, EVL cells undergo ectopic cell fusion in conditions in which oriented-cell division is impaired or the epithelium is mechanically challenged. Taken together our study of EVL epiboly suggests a novel mechanism of force generation for actomyosin rings through friction-resisted cortical flow and highlights the importance of tension-oriented cell divisions in epithelial morphogenesis."}],"language":[{"iso":"eng"}],"citation":{"chicago":"Behrndt, Martin. “Forces Driving Epithelial Spreading in Zebrafish Epiboly.” Institute of Science and Technology Austria, 2014.","apa":"Behrndt, M.

The most classical case is that of embeddings (i.e., maps without double points) of a κ-dimensional complex K into ℝ2κ. For this problem, the work of van Kampen, Shapiro, and Wu provides an efficiently testable necessary condition for embeddability (namely, vanishing of the van Kampen ob-struction). For κ ≥ 3, the condition is also sufficient, and yields a polynomial-time algorithm for deciding embeddability: One starts with an arbitrary map f : K→ℝ2κ, which generically has finitely many double points; if k ≥ 3 and if the obstruction vanishes then one can successively remove these double points by local modifications of the map f. One of the main tools is the famous Whitney trick that permits eliminating pairs of double points of opposite intersection sign. We are interested in generalizing this approach to intersection points of higher multiplicity. We call a point y 2 ℝd an r-fold Tverberg point of a map f : Kκ →ℝd if y lies in the intersection f(σ1)∩. ∩f(σr) of the images of r pairwise disjoint simplices of K. The analogue of (non-)embeddability that we study is the problem Tverbergκ r→d: Given a κ-dimensional complex K, does it satisfy a Tverberg-type theorem with parameters r and d, i.e., does every map f : K κ → ℝd have an r-fold Tverberg point? Here, we show that for fixed r, κ and d of the form d = rm and k = (r-1)m, m ≥ 3, there is a polynomial-time algorithm for deciding this (based on the vanishing of a cohomological obstruction, as in the case of embeddings). Our main tool is an r-fold analogue of the Whitney trick: Given r pairwise disjoint simplices of K such that the intersection of their images contains two r-fold Tverberg points y+ and y- of opposite intersection sign, we can eliminate y+ and y- by a local isotopy of f. In a subsequent paper, we plan to develop this further and present a generalization of the classical Haeiger-Weber Theorem (which yields a necessary and sufficient condition for embeddability of κ-complexes into ℝd for a wider range of dimensions) to intersection points of higher multiplicity.","lang":"eng"}],"related_material":{"record":[{"relation":"dissertation_contains","id":"1123","status":"public"}]},"month":"06","year":"2014","publication_status":"published","file_date_updated":"2020-07-14T12:45:30Z","page":"171 - 180","author":[{"id":"32BF9DAA-F248-11E8-B48F-1D18A9856A87","full_name":"Mabillard, Isaac","first_name":"Isaac","last_name":"Mabillard"},{"first_name":"Uli","orcid":"0000-0002-1494-0568","last_name":"Wagner","id":"36690CA2-F248-11E8-B48F-1D18A9856A87","full_name":"Wagner, Uli"}],"file":[{"file_size":914396,"checksum":"2aae223fee8ffeaf57bbabd8d92b6a2c","file_name":"IST-2016-534-v1+1_Eliminating_Tverberg_points_I._An_analogue_of_the_Whitney_trick.pdf","file_id":"4735","date_updated":"2020-07-14T12:45:30Z","creator":"system","relation":"main_file","access_level":"open_access","content_type":"application/pdf","date_created":"2018-12-12T10:09:12Z"}],"acknowledgement":"Swiss National Science Foundation (Project SNSF-PP00P2-138948)","doi":"10.1145/2582112.2582134","publisher":"ACM","conference":{"name":"SoCG: Symposium on Computational Geometry","start_date":"2014-06-08","location":"Kyoto, Japan","end_date":"2014-06-11"},"_id":"2159","date_published":"2014-06-08T00:00:00Z","quality_controlled":"1","day":"08","department":[{"_id":"UlWa"}],"user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","title":"Eliminating Tverberg points, I.

Two main factors are known to influence dispersal evolution: spatio-temporal variation in the environment and relatedness between individuals. However, the relation between these factors is still poorly understood, and they are usually treated separately. In this article, I present a theoretical framework that contains and connects effects of both environmental variation and relatedness, and reproduces and extends their known features. Spatial habitat variation selects for balanced dispersal strategies, whereby the population is kept at an ideal free distribution. Within this class of dispersal strategies, I explain how increased dispersal is promoted by perturbations to the dispersal type frequencies. An explicit formula shows the magnitude of the selective advantage of increased dispersal in terms of the spatial variability in the frequencies of the different dispersal strategies present. These variances are capable of capturing various sources of stochasticity and hence establish a common scale for their effects on the evolution of dispersal. The results furthermore indicate an alternative approach to identifying effects of relatedness on dispersal evolution."}],"external_id":{"isi":["000346736200003"]},"has_accepted_license":"1","status":"public","publication":"Ecology and Evolution","publist_id":"5049","oa_version":"Published Version","scopus_import":"1","date_created":"2018-12-11T11:55:16Z","corr_author":"1","type":"journal_article","ec_funded":1,"citation":{"apa":"Novak, S.

We investigate the effects of fluctuations of annual precipitation on ecohydrological dynamics. Specifically, we use the advanced weather generator, AWE‐GEN, to simulate 200 years of hourly meteorological forcing obtained by imposing four types of precipitation annual process with identical long‐term mean. The generated time series force a mechanistic ecohydrological model, Tethys‐Chloris. Simulations with perturbed precipitation variability are performed for four locations characterized by different vegetation cover and climate. The results indicate that long‐term transpiration (T) and evapotranspiration (ET) fluxes as well as vegetation productivity expressed as Gross Primary Production (GPP) and Aboveground Net Primary Production (ANPP) are essentially unaffected by the imposed climate fluctuations. This finding supports the hypothesis of a relative insensitivity, except for water‐limited environments, of interannual evapotranspiration and vegetation productivity to annual climatic fluctuations, which are mostly reflected in the fluxes of deep leakage and runoff. The occurrence of short periods of favorable meteorological conditions randomly taking place within the year was found to be a better explanatory variable for interannual variability of ET and ANPP than average annual or growing season conditions. The results indicated that local, single‐site sensitivities are considerably smaller than those observed across climatic and vegetation spatial gradients and thus an important role of ecosystem reorganization in modifying ANPP and ET sensitivity in a changing climate is recognized.","lang":"eng"}],"type":"journal_article","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1002/2013WR015044"}],"date_created":"2026-07-27T12:30:24Z","scopus_import":"1","publication":"Water Resources Research","oa_version":"Published Version","language":[{"iso":"eng"}],"article_type":"original","citation":{"chicago":"Fatichi, Simone, and Valeriy Y.

A certain level of uncertainty has always existed in water resources planning, but the speed and intensity of changes in baseline conditions that climate change embodies might require a shift in perspective. This article draws on both the social and physical science results of the EU-FP7 ACQWA project to better understand the challenges and opportunities for adaptation to climate change impacts on the hydrology of the upper Rhone basin in the Canton Valais, Switzerland. It first presents the results of hydro-climatic change projections downscaled to more temporally and spatially-relevant frames of reference for decision makers. Then, it analyses the current policy and legislative framework within which these changes will take place, according to the policy coherence across different water-relevant frameworks as well as the integration and mainstreaming of climate change. It compares the current policy and legislative frameworks for different aspects of water resources management to the projected impacts of climate change on the hydrology of the upper Rhone basin, in order to examine the appropriateness of the current approach for responding to a changing climatic context. Significant uncertainties pose numerous challenges in the governance context. The study draws on adaptive governance principles, to propose policy actions across different scales of governance to better manage baseline variability as well as more ‘unpredictable’ uncertainty from climate change impacts."}],"status":"public","scopus_import":"1","date_created":"2026-07-27T12:30:24Z","oa_version":"None","publication":"Environmental Science & Policy","type":"journal_article","citation":{"chicago":"Clarvis, Margot Hill, Simone Fatichi, Andrew Allan, Jürg Fuhrer, Markus Stoffel, Franco Romerio, Ludovic Gaudard, et al. “Governing and Managing Water Resources under Changing Hydro-Climatic Contexts: The Case of the Upper Rhone Basin.” <i>Environmental Science &#38; Policy</i>.

They are typically subjected to management practices that can change the biophysical structure of the canopy through defoliation and can alter soil hydraulic properties. These modifications have the potential to impact hydrological and energy fluxes as well as the primary productivity of grasslands. We investigate how a series of management practices, such as grass cut, grazing, and the consequent soil compaction due to treading by animals are affecting water resources, flood generation, and grassland productivity in a subalpine region. Results are obtained using a mechanistic ecohydrological model, Tethys-Chloris. The model is first confirmed using energy, water, and carbon fluxes measured at three eddy covariance stations over grasslands in Switzerland and discharge measured in a small experimental catchment. A series of virtual experiments are then designed to elucidate the importance of various management scenarios at the plot and catchment scales. Results show that only severe management actions such as low grass cuts or heavy grazing are able to influence considerably the long-term hydrological behavior. Moderate management practices are typically unable to modify the system response in terms of energy and water fluxes. An important short-term effect is represented by animal-induced soil compaction that can reduce infiltration capacity leading to peak flow considerably higher than in undisturbed conditions. The productivity of vegetation in absence of nutrient limitation is considerably affected by the different management scenarios with tolerable disturbances that lead to higher aboveground net primary production.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1002/2013WR014535"}],"type":"journal_article","scopus_import":"1","oa_version":"Published Version","date_created":"2026-07-27T12:30:24Z","publication":"Water Resources Research","month":"01","volume":50,"issue":"1","publication_status":"published","year":"2014","page":"148-164","author":[{"first_name":"Simone","last_name":"Fatichi","full_name":"Fatichi, Simone","id":"cf8e546b-a9b0-11f0-a43b-aa89ed1b56d6"},{"full_name":"Zeeman, Matthias J.","first_name":"Matthias J.","last_name":"Zeeman"},{"full_name":"Fuhrer, Jürg","first_name":"Jürg","last_name":"Fuhrer"},{"first_name":"Paolo","last_name":"Burlando","full_name":"Burlando, Paolo"}]},{"author":[{"last_name":"Paschalis","first_name":"Athanasios","full_name":"Paschalis, Athanasios"},{"id":"cf8e546b-a9b0-11f0-a43b-aa89ed1b56d6","full_name":"Fatichi, Simone","first_name":"Simone","last_name":"Fatichi"},{"full_name":"Molnar, Peter","last_name":"Molnar","first_name":"Peter"},{"last_name":"Rimkus","first_name":"Stefan","full_name":"Rimkus, Stefan"},{"first_name":"Paolo","last_name":"Burlando","full_name":"Burlando, Paolo"}],"page":"313-327","publication_status":"published","year":"2014","month":"06","volume":514,"abstract":[{"lang":"eng","text":"The spatio-temporal variability of rainfall, especially at fine temporal and spatial scales can significantly affect flood generation, leading to a large variability in the flood response and uncertainty in its prediction. In this study we quantify the impact of rainfall spatial and temporal structure on the catchment hydrological response based on a numerical experiment. Rainfall ensembles generated using a state-of-the-art space–time stochastic model are used as input into a distributed process-based hydrological model. The sensitivity of the hydrograph to several structural characteristics of storm rainfall for three soil moisture initial conditions is numerically assessed at the basin outlet of an Alpine catchment in central Switzerland. The results highlight that the flood response is strongly affected by the temporal correlation of rainfall and to a lesser extent by its spatial variability. Initial soil moisture conditions play a paramount role in mediating the response. We identify the underlying mechanistic explanations in terms of runoff generation and connectivity of saturated areas that determine the sensitivity of flood response to the spatio-temporal variability of rainfall. We show that the element that mostly influences both the flood peak and the time of peak occurrence is the clustering of saturated areas in the catchment which leads to local enhanced runoff."}],"status":"public","publication":"Journal of Hydrology","scopus_import":"1","oa_version":"None","date_created":"2026-07-27T12:30:25Z","type":"journal_article","article_type":"original","citation":{"chicago":"Paschalis, Athanasios, Simone Fatichi, Peter Molnar, Stefan Rimkus, and Paolo Burlando. “On the Effects of Small Scale Space–Time Variability of Rainfall on Basin Flood Response.” <i>Journal of Hydrology</i>.

The rationale is that a combination of stochastic precipitation models which are most appropriate for specific limited temporal scales leads to better overall performance across a wider range of scales than single models alone. We investigate different model combinations. For the coarse (daily) scale these are models based on Alternating renewal processes, Markov chains, and Poisson cluster models, which are then combined with a microcanonical Multiplicative Random Cascade model to disaggregate precipitation to finer (minute) scales. The composite models were tested on data at four sites in different climates. The results show that model combinations improve the performance in key statistics such as probability distributions of precipitation depth, autocorrelation structure, intermittency, reproduction of extremes, compared to single models. At the same time they remain reasonably parsimonious. No model combination was found to outperform the others at all sites and for all statistics, however we provide insight on the capabilities of specific model combinations. The results for the four different climates are similar, which suggests a degree of generality and wider applicability of the approach.","lang":"eng"}],"status":"public","date_created":"2026-07-27T12:30:25Z","scopus_import":"1","publication":"Advances in Water Resources","oa_version":"None","type":"journal_article","keyword":["Stochastic rainfall models","Poisson cluster model","Multiplicative Random Cascade","Markov chain","Alternating renewal process"],"day":"01","title":"On temporal stochastic modeling of precipitation, nesting models across scales","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","publication_identifier":{"issn":["0309-1708"]},"article_processing_charge":"No","publisher":"Elsevier","doi":"10.1016/j.advwatres.2013.11.006","extern":"1","_id":"22575","quality_controlled":"1","date_published":"2014-01-01T00:00:00Z","das_tickbox":"1"},{"author":[{"first_name":"Mato","last_name":"Lagator","id":"345D25EC-F248-11E8-B48F-1D18A9856A87","full_name":"Lagator, Mato"},{"full_name":"Colegrave, Nick","last_name":"Colegrave","first_name":"Nick"},{"last_name":"Neve","first_name":"Paul","full_name":"Neve, Paul"}],"related_material":{"record":[{"status":"public","id":"9741","relation":"research_data"}]},"issue":"1794","volume":281,"month":"09","year":"2014","publication_status":"published","citation":{"chicago":"Lagator, Mato, Nick Colegrave, and Paul Neve. “Selection History and Epistatic Interactions Impact Dynamics of Adaptation to Novel Environmental Stresses.” <i>Proceedings of the Royal Society of London Series B Biological Sciences</i>.

Mutations selected in one environment may result in pleiotropic fitness trade-offs in subsequent novel environments, slowing the rates of adaptation. Epistatic interactions between mutations selected in sequential stressful environments may slow or accelerate subsequent rates of adaptation, depending on the nature of that interaction. We explored the dynamics of adaptation during sequential exposure to herbicides with different modes of action in Chlamydomonas reinhardtii. Evolution of resistance to two of the herbicides was largely independent of selection history. For carbetamide, previous adaptation to other herbicide modes of action positively impacted the likelihood of adaptation to this herbicide. Furthermore, while adaptation to all individual herbicides was associated with pleiotropic fitness costs in stress-free environments, we observed that accumulation of resistance mechanisms was accompanied by a reduction in overall fitness costs. We suggest that antagonistic epistasis may be a driving mechanism that enables populations to more readily adapt in novel environments. These findings highlight the potential for sequences of xenobiotics to facilitate the rapid evolution of multiple-drug and -pesticide resistance, as well as the potential for epistatic interactions between adaptive mutations to facilitate evolutionary rescue in rapidly changing environments.
