text: 'Changes in rainfall amounts and patterns have been observed and are expected
to continue in the near future with potentially significant ecological and societal
consequences. Modelling vegetation responses to changes in rainfall is thus crucial
to project water and carbon cycles in the future. In this study, we present the
results of a new model‐data intercomparison project, where we tested the ability
of 10 terrestrial biosphere models to reproduce the observed sensitivity of ecosystem
productivity to rainfall changes at 10 sites across the globe, in nine of which,
rainfall exclusion and/or irrigation experiments had been performed. The key results
are as follows: (a) Inter‐model variation is generally large and model agreement
varies with timescales. In severely water‐limited sites, models only agree on
the interannual variability of evapotranspiration and to a smaller extent on gross
primary productivity. In more mesic sites, model agreement for both water and
carbon fluxes is typically higher on fine (daily–monthly) timescales and reduces
on longer (seasonal–annual) scales. (b) Models on average overestimate the relationship
between ecosystem productivity and mean rainfall amounts across sites (in space)
and have a low capacity in reproducing the temporal (interannual) sensitivity
of vegetation productivity to annual rainfall at a given site, even though observation
uncertainty is comparable to inter‐model variability. (c) Most models reproduced
the sign of the observed patterns in productivity changes in rainfall manipulation
experiments but had a low capacity in reproducing the observed magnitude of productivity
changes. Models better reproduced the observed productivity responses due to rainfall
exclusion than addition. (d) All models attribute ecosystem productivity changes
to the intensity of vegetation stress and peak leaf area, whereas the impact of
the change in growing season length is negligible. The relative contribution of
the peak leaf area and vegetation stress intensity was highly variable among models.'

text: "The vadose zone is a zone sensitive to environmental\r\nchanges and exerts
a crucial control in ecosystem functioning and even more\r\nso in cold regions
considering the rapid change in seasonally frozen ground\r\nunder climate warming.
While the way in representing the underlying physical\r\nprocess of the vadose
zone differs among models, the effect of such differences\r\non ecosystem functioning
and its ecohydrological response to freeze–thaw\r\ncycles are seldom reported.
Here, the detailed vadose zone process model\r\nSTEMMUS (Simultaneous Transfer
of Energy, Mass\r\nand Momentum in Unsaturated Soil) was coupled with the ecohydrological
model Tethys–Chloris (T&C) to investigate the\r\nrole of influential physical
processes during freeze–thaw cycles. The\r\nphysical representation is increased
from using T&C coupling without STEMMUS enabling the\r\nsimultaneous mass
and energy transfer in the soil system (liquid, vapor,\r\nice) – and with\r\nexplicit
consideration of the impact of soil ice content on energy and water\r\ntransfer
properties – to using T&C coupling with it. We tested model performance
with the aid of a comprehensive\r\nobservation dataset collected at a typical
meadow ecosystem on the Tibetan\r\nPlateau. Results indicated that (i) explicitly
considering the frozen soil\r\nprocess significantly improved the soil moisture/temperature
profile\r\nsimulations and facilitated our understanding of the water transfer\r\nprocesses
within the soil–plant–atmosphere continuum; (ii) the difference\r\namong various
representations of vadose zone physics have an impact on the\r\nvegetation dynamics
mainly at the beginning of the growing season; and (iii) models with different
vadose zone physics can predict similar interannual\r\nvegetation dynamics, as
well as energy, water, and carbon exchanges, at the land\r\nsurface. This research
highlights the important role of vadose zone physics\r\nfor ecosystem functioning
in cold regions and can support the development\r\nand application of future Earth
system models."

text: Groundwater can have a critical role in sustaining the functioning of natural
ecosystems during droughts, especially in dry and seasonally dry climates. However,
the response to droughts of ecosystems embedded in urban areas is not well known.
This study investigates how different scenarios of groundwater availability control
the water balance and vegetation productivity of two urban reserves hosting native
vegetation in the Melbourne metropolitan area, Australia. Using a mechanistic
ecohydrological model supported by field observations, long-term simulations were
run to explore the impact of groundwater flow on water, carbon, and energy fluxes
under present climatic conditions, including the Millennium Drought (2001–2009),
and in response to perturbations in key environmental variables (air temperature,
atmospheric CO2 concentrations, and rainfall). It was found that the presence
of a water table and its capillary fringe within the root depths supports ecosystem
transpiration and vegetation productivity. The effects of declining groundwater
were found to be more severe in predominantly sandy soils because of the lower
water holding capacity, identifying that the water status of vegetation differs
significantly depending on soil type. Differences in rooting strategies and groundwater
availability also had a pivotal role in helping plants soften the impacts of increased
air temperature (Ta) and make use of higher atmospheric CO2 concentrations. Increased
Ta strongly affected evapotranspiration, enhancing the competition for water between
different vegetation types. These results provide quantitative insights of how
vegetation responds to groundwater depletion and climate variability, highlighting
the essential role of groundwater resources in urban ecosystems characterized
by seasonally dry climates.

text: The boreal biome accounts for approximately one third of the terrestrial carbon
(C) sink. However, estimates of its individual C pools remain uncertain. Here,
focusing on the southern boreal forest, we quantified the magnitude and temporal
dynamics of C allocation to aboveground tree growth at a mature black spruce (Picea
mariana)-dominated forest stand in Saskatchewan, Canada. We reconstructed aboveground
tree biomass increments (AGBi) using a biometric approach, i.e., species-specific
allometry combined with forest stand characteristics and tree ring widths collected
with a C-oriented sampling design. We explored the links between boreal tree growth
and ecosystem C input by comparing AGBi with eddy-covariance-derived ecosystem
C fluxes from 1999 to 2015 and we synthesized our findings with a refined meta-analysis
of published values of boreal forest C use efficiency (CUE). Mean AGBi at the
study site was decoupled from ecosystem C input and equal to 71 ± 7 g C m–2 (1999–2015),
which is only a minor fraction of gross ecosystem production (GEP; i.e., AGBi
/ GEP ≈ 9 %). Moreover, C allocation to AGBi remained stable over time (AGBi /
GEP; –0.0001 yr–1; p-value=0.775), contrary to significant trends in GEP (+5.72
g C m–2 yr–2; p-value=0.02) and CUE (–0.0041 yr–1, p-value=0.007). CUE was estimated
as 0.50 ± 0.03 at the study area and 0.41 ± 0.12 across the reviewed boreal forests.
These findings highlight the importance of belowground tree C investments, together
with the substantial contribution of understory, ground cover and soil to the
boreal forest C balance. Our quantitative insights into the dynamics of aboveground
boreal tree C allocation offer additional observational constraints for terrestrial
ecosystem models that are often biased in converting C input to biomass, and can
guide forest-management strategies for mitigating carbon dioxide emissions.

text: "A search problem lies in the complexity class FNP if a solution to the given
instance of the problem can be verified efficiently. The complexity class TFNP
consists of all search problems in FNP that are total in the sense that a solution
is guaranteed to exist. TFNP contains a host of interesting problems from fields
such as algorithmic game theory, computational topology, number theory and combinatorics.
Since TFNP is a semantic class, it is unlikely to have a complete problem. Instead,
one studies its syntactic subclasses which are defined based on the combinatorial
principle used to argue totality. Of particular interest is the subclass PPAD,
which contains important problems\r\nlike computing Nash equilibrium for bimatrix
games and computational counterparts of several fixed-point theorems as complete.
In the thesis, we undertake the study of averagecase hardness of TFNP, and in
particular its subclass PPAD.\r\nAlmost nothing was known about average-case hardness
of PPAD before a series of recent results showed how to achieve it using a cryptographic
primitive called program obfuscation.\r\nHowever, it is currently not known how
to construct program obfuscation from standard cryptographic assumptions. Therefore,
it is desirable to relax the assumption under which average-case hardness of PPAD
can be shown. In the thesis we take a step in this direction. First, we show that
assuming the (average-case) hardness of a numbertheoretic\r\nproblem related to
factoring of integers, which we call Iterated-Squaring, PPAD is hard-on-average
in the random-oracle model. Then we strengthen this result to show that the average-case
hardness of PPAD reduces to the (adaptive) soundness of the Fiat-Shamir Transform,
a well-known technique used to compile a public-coin interactive protocol into
a non-interactive one. As a corollary, we obtain average-case hardness for PPAD
in the random-oracle model assuming the worst-case hardness of #SAT. Moreover,
the above results can all be strengthened to obtain average-case hardness for
the class CLS ⊆ PPAD.\r\nOur main technical contribution is constructing incrementally-verifiable
procedures for computing Iterated-Squaring and #SAT. By incrementally-verifiable,
we mean that every intermediate state of the computation includes a proof of its
correctness, and the proof can be updated and verified in polynomial time. Previous
constructions of such procedures relied on strong, non-standard assumptions. Instead,
we introduce a technique called recursive proof-merging to obtain the same from
weaker assumptions. "

text: "Heavy rainfall is expected to intensify with increasing\r\ntemperatures,
which will likely affect rainfall spatial characteristics. The\r\nspatial variability
of rainfall can affect streamflow and sediment transport\r\nvolumes and peaks.
Yet, the effect of climate change on the small-scale\r\nspatial structure of heavy
rainfall and subsequent impacts on hydrology and\r\ngeomorphology remain largely
unexplored. In this study, the sensitivity of\r\nthe hydro-morphological response
to heavy rainfall at the small-scale\r\nresolution of minutes and hundreds of
metres was investigated. A numerical\r\nexperiment was conducted in which synthetic
rainfall fields representing\r\nheavy rainfall events of two types, stratiform
and convective, were\r\nsimulated using a space-time rainfall generator model.
The rainfall fields\r\nwere modified to follow different spatial rainfall scenarios
associated\r\nwith increasing temperatures and used as inputs into a landscape
evolution\r\nmodel. The experiment was conducted over a complex topography, a
medium-sized\r\n(477 km2) Alpine catchment in central Switzerland. It was found
that\r\nthe responses of the streamflow and sediment yields are highly sensitive
to\r\nchanges in total rainfall volume and to a lesser extent to changes in local\r\npeak
rainfall intensities. The results highlight that the morphological\r\ncomponents
are more sensitive to changes in rainfall spatial structure in\r\ncomparison to
the hydrological components. The hydro-morphological features\r\nwere found to
respond more to convective rainfall than stratiform rainfall\r\nbecause of localized
runoff and erosion production. It is further shown that\r\nassuming heavy rainfall
to intensify with increasing temperatures without\r\nintroducing changes in the
rainfall spatial structure might lead to\r\noverestimation of future climate impacts
on basin hydro-morphology."

text: Most soil hydraulic information used in Earth System Models (ESMs) is derived
from pedo-transfer functions that use easy-to-measure soil attributes to estimate
hydraulic parameters. This parameterization relies heavily on soil texture, but
overlooks the critical role of soil structure originated by soil biophysical activity.
Soil structure omission is pervasive also in sampling and measurement methods
used to train pedotransfer functions. Here we show how systematic inclusion of
salient soil structural features of biophysical origin affect local and global
hydrologic and climatic responses. Locally, including soil structure in models
significantly alters infiltration-runoff partitioning and recharge in wet and
vegetated regions. Globally, the coarse spatial resolution of ESMs and their inability
to simulate intense and short rainfall events mask effects of soil structure on
surface fluxes and climate. Results suggest that although soil structure affects
local hydrologic response, its implications on global-scale climate remains elusive
in current ESMs.

text: Solutes in rivers often come from multiple sources, notably precipitation
(above) and generation from the subsurface (below). The question of which source
is more influential in shaping the dynamics of solute concentration cannot be
easily addressed due to the general lack of input data. An analysis of solute
concentrations and their dependence on discharge across 585 catchments in nine
countries leads us to hypothesize that both the timing and the vertical distribution
of the solute generation are important drivers of solute export dynamics at the
catchment scale. We test this hypothesis running synthetic experiments with a
tracer-aided distributed hydrological model. The results reveal that the depth
of solute generation is the most important control of the concentration-discharge
(C-Q) relation for a number of solutes. Such relation shows that C-Q patterns
of solute export vary from dilution (Ca2+, Mg2+, K+, Na+, and Cl−) to weakly enriching
(dissolved organic carbon). The timing of the input imposes a signature on temporal
dynamics, most evident for nutrients, and adds uncertainty in the exponent of
the C-Q relation.

text: An asymptotic formula is established for the number of rational points of
bounded anticanonical height which lie on a certain Zariski dense subset of the
biprojective hypersurface x1y21+⋯+x4y24=0 in ℙ3×ℙ3. This confirms the modified
Manin conjecture for this variety, in which the removal of a thin set of rational
points is allowed.

text: Increasing urbanization is likely to intensify the urban heat island effect,
decrease outdoor thermal comfort, and enhance runoff generation in cities. Urban
green spaces are often proposed as a mitigation strategy to counteract these adverse
effects, and many recent developments of urban climate models focus on the inclusion
of green and blue infrastructure to inform urban planning. However, many models
still lack the ability to account for different plant types and oversimplify the
interactions between the built environment, vegetation, and hydrology. In this
study, we present an urban ecohydrological model, Urban Tethys-Chloris (UT&C),
that combines principles of ecosystem modelling with an urban canopy scheme accounting
for the biophysical and ecophysiological characteristics of roof vegetation, ground
vegetation, and urban trees. UT&C is a fully coupled energy and water balance
model that calculates 2 m air temperature, 2 m humidity, and surface temperatures
based on the infinite urban canyon approach. It further calculates the urban hydrological
fluxes in the absence of snow, including transpiration as a function of plant
photosynthesis. Hence, UT&C accounts for the effects of different plant types
on the urban climate and hydrology, as well as the effects of the urban environment
on plant well-being and performance. UT&C performs well when compared against
energy flux measurements of eddy-covariance towers located in three cities in
different climates (Singapore, Melbourne, and Phoenix). A sensitivity analysis,
performed as a proof of concept for the city of Singapore, shows a mean decrease
in 2 m air temperature of 1.1 ∘C for fully grass-covered ground, 0.2 ∘C for high
values of leaf area index (LAI), and 0.3 ∘C for high values of Vc,max (an expression
of photosynthetic capacity). These reductions in temperature were combined with
a simultaneous increase in relative humidity by 6.5 %, 2.1 %, and 1.6 %, for fully
grass-covered ground, high values of LAI, and high values of Vc,max, respectively.
Furthermore, the increase of pervious vegetated ground is able to significantly
reduce surface runoff.

text: Climate change can reduce surface-water supply by enhancing evapotranspiration
in forested mountains, especially during heatwaves. We investigate this ‘drought
paradox’ for the European Alps using a 1,212-station database and hyper-resolution
ecohydrological simulations to quantify blue (runoff) and green (evapotranspiration)
water fluxes. During the 2003 heatwave, evapotranspiration in large areas over
the Alps was above average despite low precipitation, amplifying the runoff deficit
by 32% in the most runoff-productive areas (1,300–3,000 m above sea level). A
3 °C air temperature increase could enhance annual evapotranspiration by up to
100 mm (45 mm on average), which would reduce annual runoff at a rate similar
to a 3% precipitation decrease. This suggests that green-water feedbacks—which
are often poorly represented in large-scale model simulations—pose an additional
threat to water resources, especially in dry summers. Despite uncertainty in the
validation of the hyper-resolution ecohydrological modelling with observations,
this approach permits more realistic predictions of mountain region water availability.

text: Temporal dynamics of urban warming have been extensivelystudied at the diurnal
scale, but the impact of background cli-mate on the observed seasonality of surface
urban heat islands(SUHIs) remains largely unexplored. On seasonal time scales,
theintensity of urban–rural surface temperature differences (∆Ts)exhibits distinctive
hysteretic cycles whose shape and loopingdirection vary across climatic zones.
These observations high-light possible delays underlying the dynamics of the coupledurban–biosphere
system. However, a general argument explain-ing the observed hysteretic patterns
remains elusive. A coarse-grained model of SUHI coupled with a stochastic soil
waterbalance is developed to demonstrate that the time lags betweenradiation forcing,
air temperature, and rainfall generate a rate-dependent hysteresis, explaining
the observed seasonal varia-tions of ∆Ts. If solar radiation is in phase with
water availability,summer conditions cause strong SUHI intensities due to highrural
evaporative cooling. Conversely, cities in seasonally dryregions where evapotranspiration
is out of phase with radia-tion show a summertime oasis effect controlled by backgroundclimate
and vegetation properties. These seasonal patterns ofwarming and cooling have
significant implications for heat mit-igation strategies as urban green spaces
can reduce ∆Ts duringsummertime, while potentially negative effects of albedo
man-agement during winter are mitigated by the seasonality of solarradiation.

text: We give the first mathematically rigorous justification of the local density
approximation in density functional theory. We provide a quantitative estimate
on the difference between the grand-canonical Levy–Lieb energy of a given density
(the lowest possible energy of all quantum states having this density) and the
integral over the uniform electron gas energy of this density. The error involves
gradient terms and justifies the use of the local density approximation in the
situation where the density is very flat on sufficiently large regions in space.

text: We give a Wong-Zakai type characterisation of the solutions of quasilinear
heat equations driven by space-time white noise in 1 + 1 dimensions. In order
to show that the renormalisation counterterms are local in the solution, a careful
arrangement of a few hundred terms is required. The main tool in this computation
is a general ‘integration by parts’ formula that provides a number of linear identities
for the renormalisation constants.

text: This work analyzes the latency of the simplified successive cancellation (SSC)
decoding scheme for polar codes proposed by Alamdar-Yazdi and Kschischang. It
is shown that, unlike conventional successive cancellation decoding, where latency
is linear in the block length, the latency of SSC decoding is sublinear. More
specifically, the latency of SSC decoding is O(N 1−1/µ ), where N is the block
length and µ is the scaling exponent of the channel, which captures the speed
of convergence of the rate to capacity. Numerical results demonstrate the tightness
of the bound and show that most of the latency reduction arises from the parallel
decoding of subcodes of rate 0 and 1.

text: The growth of snail shells can be described by simple mathematical rules.
Variation in a few parameters can explain much of the diversity of shell shapes
seen in nature. However, empirical studies of gastropod shell shape variation
typically use geometric morphometric approaches, which do not capture this growth
pattern. We have developed a way to infer a set of developmentally descriptive
shape parameters based on three-dimensional logarithmic helicospiral growth and
using landmarks from two-dimensional shell images as input. We demonstrate the
utility of this approach, and compare it to the geometric morphometric approach,
using a large set of Littorina saxatilis shells in which locally adapted populations
differ in shape. Our method can be modified easily to make it applicable to a
wide range of shell forms, which would allow for investigations of the similarities
and differences between and within many different species of gastropods.

text: 'In many real-world systems, information can be transmitted in two qualitatively
different ways: by copying or by transformation. Copying occurs when messages
are transmitted without modification, e.g. when an offspring receives an unaltered
copy of a gene from its parent. Transformation occurs when messages are modified
systematically during transmission, e.g. when mutational biases occur during genetic
replication. Standard information-theoretic measures do not distinguish these
two modes of information transfer, although they may reflect different mechanisms
and have different functional consequences. Starting from a few simple axioms,
we derive a decomposition of mutual information into the information transmitted
by copying versus the information transmitted by transformation. We begin with
a decomposition that applies when the source and destination of the channel have
the same set of messages and a notion of message identity exists. We then generalize
our decomposition to other kinds of channels, which can involve different source
and destination sets and broader notions of similarity. In addition, we show that
copy information can be interpreted as the minimal work needed by a physical copying
process, which is relevant for understanding the physics of replication. We use
the proposed decomposition to explore a model of amino acid substitution rates.
Our results apply to any system in which the fidelity of copying, rather than
simple predictability, is of critical relevance.'

text: "We introduce “state space persistence analysis” for deducing the symbolic
dynamics of time series data obtained from high-dimensional chaotic attractors.
To this end, we adapt a topological data analysis technique known as persistent
homology for the characterization of state space projections of chaotic trajectories
and periodic orbits. By comparing the shapes along a chaotic trajectory to those
of the periodic orbits, state space persistence analysis quantifies the shape
similarity of chaotic trajectory segments and periodic orbits. We demonstrate
the method by applying it to the three-dimensional Rössler system and a 30-dimensional
discretization of the Kuramoto–Sivashinsky partial differential equation in (1+1)
dimensions.\r\nOne way of studying chaotic attractors systematically is through
their symbolic dynamics, in which one partitions the state space into qualitatively
different regions and assigns a symbol to each such region.1–3 This yields a “coarse-grained”
state space of the system, which can then be reduced to a Markov chain encoding
all possible transitions between the states of the system. While it is possible
to obtain the symbolic dynamics of low-dimensional chaotic systems with standard
tools such as Poincaré maps, when applied to high-dimensional systems such as
turbulent flows, these tools alone are not sufficient to determine symbolic dynamics.4,5
In this paper, we develop “state space persistence analysis” and demonstrate that
it can be utilized to infer the symbolic dynamics in very high-dimensional settings."
