text: Reproduction is a fundamental biological process, with organisms reproducing
sexually, asexually, and, in some cases, utilizing both modes of reproduction
within the same population. Does the ability to reproduce through a combination
of asexual and sexual modes offer an evolutionary advantage over relying on either
mode alone? Here, we introduce an empirically driven theoretical model to examine
the dynamics and interplay between sexual and asexual reproduction in stick insect
populations. We analyse it using a novel phase transition approach and corroborate
it using published experimental data. We find that the presence of males can either
increase or decrease the overall population size. However, maintaining an optimal
ratio of parthenogenetic to sexual reproduction is crucial for male resilience,
effectively delaying male extinction. Conversely, extreme levels of parthenogenetic
reproduction—whether too high or too low—can lead to male extinction, emphasizing
the need for a balanced number of virgin females to ensure the persistence of
males. Our model also explains male absence in Carausius morosus and persistence
in Extatosoma tiaratum. Our findings provide valuable insights into the interplay
of reproductive strategies and contribute to broader discussions on the transitions
between sexual and asexual reproduction.

text: 'Natural selection is usually studied between mutants that differ in reproductive
rate, but are subject to the same population structure. Here we explore how natural
selection acts on mutants that have the same reproductive rate, but different
population structures. In our framework, population structure is given by a graph
that specifies where offspring can disperse. The invading mutant disperses offspring
on a different graph than the resident wild-type. We find that more densely connected
dispersal graphs tend to increase the invader’s fixation probability, but the
exact relationship between structure and fixation probability is subtle. We present
three main results. First, we prove that if both invader and resident are on complete
dispersal graphs, then removing a single edge in the invader’s dispersal graph
reduces its fixation probability. Second, we show that for certain island models
higher invader’s connectivity increases its fixation probability, but the magnitude
of the effect depends on the exact layout of the connections. Third, we show that
for lattices the effect of different connectivity is comparable to that of different
fitness: for large population size, the invader’s fixation probability is either
constant or exponentially small, depending on whether it is more or less connected
than the resident.'

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 consider a class of students learning a language from a teacher. The situation
can be interpreted as a group of child learners receiving input from the linguistic
environment. The teacher provides sample sentences. The students try to learn
the grammar from the teacher. In addition to just listening to the teacher, the
students can also communicate with each other. The students hold hypotheses about
the grammar and change them if they receive counter evidence. The process stops
when all students have converged to the correct grammar. We study how the time
to convergence depends on the structure of the classroom by introducing and evaluating
various complexity measures. We find that structured communication between students,
although potentially introducing confusion, can greatly reduce some of the complexity
measures. Our theory can also be interpreted as applying to the scientific process,
where nature is the teacher and the scientists are the students.
