text: 'Males of the ant Cardiocondyla show a dispersal dimorphism of a winged and
wingless morph. The loss of flight has lead to morphological reductions in the
wingless (ergatoid) males and also affected body size, eye size and pigmentation.
As ergatoid males mate exclusively inside the maternal nest, they underlie increased
male-male competition and therefore have also evolved additional changes in behaviour
and physiology: in contrast to winged males, ergatoid males are highly aggressive
towards each other and their spermatogenesis is prolonged compared to all other
hymenopteran males. In addition to these two male morphs, we found males with
an intermediate appearance. These "intermorphic" males provide a transitional
stage between normal males in most investigated morphological and physiological
parameters. As they are produced extremely rarely and only in colonies that switch
between pure ergatoid to mixed male production, we argue that they likely represent
a developmental mistake. Parallels between the determination of male morphs and
female castes (queen-worker dimorphism and worker polymorphism) might help to
understand how the large potential of phenotypic plasticity in both sexes of social
insects is realised during development.'
acknowledgement: We would like to thank S. Karpeles for histological analysis of the
winged males and S. Buchhauser for help with the photographs. This study was funded
by the DFG (grant He1623/12–1).

text: Males of the tropical ant Cardiocondyla obscurior are either wingless and
aggressive or winged and docile, and both compete for access to virgin queens
in the nest1, 2. Although the fighter males (ergatoids) attack and kill other
ergatoids, they tolerate and even attempt to mate with their winged rivals. Here
we show that the winged males avoid the aggression of wingless males by mimicking
the chemical bouquet of virgin queens, but that their mating success is not reduced
as a result. This example of female mimicry by vigorous males is surprising, as
in other species it is typically used as a protective strategy by weaker males,
and may explain the coexistence and equal mating success of two male morphs.

text: We formalize a notion of topological simplification within the framework of
a filtration, which is the history of a growing complex. We classify a topological
change that happens during growth as either a feature or noise depending on its
lifetime or persistence within the filtration. We give fast algorithms for computing
persistence and experimental evidence for their speed and utility.

text: We present results on a two-step improvement of mesh quality in three-dimensional
Delaunay triangulations. The first step refines the triangulation by inserting
sinks and eliminates tetrahedra with large circumradius over shortest edge length
ratio. The second step assigns weights to the vertices to eliminate slivers. Our
experimental findings provide evidence for the practical effectiveness of sliver

text: We present fast implementations of a hybrid algorithm for reporting box and
cube intersections. Our algorithm initially takes a divide-and-conquer approach
and switches to simpler algorithms for low numbers of boxes. We use our implementations
as engines to solve problems about geometric primitives. We look at two such problems
in the category of quality analysis of surface triangulations.

text: The writhing number measures the global geometry of a closed space curve or
knot. We show that this measure is related to the average winding number of its
Gauss map. Using this relationship, we give an algorithm for computing the writhing
number for a polygonal knot with n edges in time roughly proportional to n(1.6).
We also implement a different, simple algorithm and provide experimental evidence
for its practical efficiency.

text: Pilot studies in England by Stopka and Macdonald revealed that allogrooming
in the Old World wood mouse, Apodemus sylvaticus, is a commodity that males can
trade for reproductive benefits with females. This study, which used a combination
of field study and observations in experimental enclosures, revealed that specific
experimental conditions such as group-size and sex-ratio manipulations have a
significant effect on the pattern of allogrooming exchanged between individuals.
Furthermore, females from the Czech population were more likely to associate with
each other as revealed by the clustering of activity centers of females (i.e.,
as opposed to almost exclusive ranges in English populations), and also by the
higher intensity of allogrooming exchanged between females (i.e., virtually lacking
in the previous experiment with English mice). Therefore, geographic variation
and specific social conditions seem to be important driving factors for allogrooming
behavior. Together with changes in overall grooming patterns, allogrooming between
males and females remained invariably asymmetrical over all four experimental
groups (i.e., two conditions for each sex) in that males provided more allogrooming
to females than they received from them.

text: Members of the Wnt family have been implicated in a variety of developmental
processes including axis formation, Patterning of the central nervous system and
tissue morphogenesis. Recent studies have shown that a Wnt signalling pathway
similar to that involved in the establishment of planar cell polarity in Drosophila
regulates convergent extension movements during zebrafish and Xenopus gastrulation.
This finding provides a good starting point to dissect the complex cell biology
and genetic regulation of vertebrate gastrulation movements.

text: Cells at the anterior boundary of the neural plate (ANB) can induce telencephalic
gene expression when transplanted to more posterior regions. Here, we identify
a secreted Frizzled-related Wnt antagonist, Tic, that is expressed in ANB cells
and can cell nonautonomously promote telencephalic gene expression in a concentration-dependent
manner. Moreover, abrogation of Tlc function compromises telencephalic development.
We also identify Wnt8b as a locally acting modulator of regional fate in the anterior
neural plate and a likely target for antagonism by Tic. Finally, we show that
tlc expression is regulated by signals that establish early antero-posterior and
dorso-ventral ectodermal pattern. From these studies, we propose that local antagonism
of Wnt activity within the anterior ectoderm is required to establish the telencephalon.

text: During vertebrate gastrulation, large cellular rearrangements lead to the
formation of the three germ layers, ectoderm, mesoderm and endoderm. Zebrafish
offer many genetic and experimental advantages for studying vertebrate gastrulation
movements. For instance, several mutants, including silberblick, knypek and trilobite,
exhibit defects in morphogenesis during gastrulation. The identification of the
genes mutated in these lines together with the analysis of the mutant phenotypes
has provided new insights into the molecular and cellular mechanisms that underlie
vertebrate gastrulation movements.

text: Vertebrate homologues of the Strabismus/van Gogh (stbm/vang) gene have been
implicated in patterning and morphogenesis during gastrulation. Recent work shows
that stbm/vang is mutated in zebrafish trilobite mutants and that stbm/vang is
required for morphogenesis but not patterning during zebrafish gastrulation.

text: We have identified widerborst (wdb), a B' regulatory subunit of PP2A, as a
conserved component of planar cell polarization mechanisms in both Drosophila
and in zebrafish. In Drosophila, wdb acts at two steps during planar polarization
of wing epithelial cells. It is required to organize tissue polarity proteins
into proximal and distal cortical domains, thus determining wing hair orientation.
It is also needed to generate the polarized membrane outgrowth that becomes the
wing hair. Widerborst activates the catalytic subunit of PP2A and localizes to
the distal side of a planar microtubule web that lies at the level of apical cell
junctions. This suggests that polarized PP2A activation along the planar microtubule
web is important for planar polarization. In zebrafish, two wdb homologs are required
for convergent extension during gastrulation, supporting the conjecture that Drosophila
planar cell polarization and vertebrate gastrulation movements are regulated by
similar mechanisms.

text: We studied the effect of multilocus balancing selection on neutral nucleotide
variability at linked sites by simulating a model where diallelic polymorphisms
are maintained at an arbitrary number of selected loci by means of symmetric overdominance.
Different combinations of alleles define different genetic backgrounds that subdivide
the population and strongly affect variability. Several multilocus fitness regimes
with different degrees of epistasis and gametic disequilibrium are allowed. Analytical
results based on a multilocus extension of the structured coalescent predict that
the expected linked neutral diversity increases exponentially with the number
of selected loci and can become extremely large. Our simulation results show that
although variability increases with the number of genetic backgrounds that are
maintained in the population, it is reduced by random fluctuations in the frequencies
of those backgrounds and does not reach high levels even in very large populations.
We also show that previous results on balancing selection in single-locus systems
do not extend to the multilocus scenario in a straightforward way. Different patterns
of linkage disequilibrium and of the frequency spectrum of neutral mutations are
expected under different degrees of epistasis. Interestingly, the power to detect
balancing selection using deviations from a neutral distribution of allele frequencies
seems to be diminished under the fitness regime that leads to the largest increase
of variability over the neutral case. This and other results are discussed in
the light of data from the Mhc.

text: 'We extend current multilocus models to describe the effects of migration,
recombination, selection, and nonrandom mating on sets of genes in diploids with
varied modes of inheritance, allowing us to consider the patterns of nuclear and
cytonuclear associations (disequilibria) under various models of migration. We
show the relationship between the multilocus notation recently presented by Kirkpatrick,
Johnson, and Barton (developed from previous work by Barton and Turelli) and the
cytonuclear parameterization of Asmussen, Arnold, and Avise and extend this notation
to describe associations between cytoplasmic elements and multiple nuclear genes.
Under models with sexual symmetry, both nuclear-nuclear and cytonuclear disequilibria
are equivalent. They differ, however, in cases involving some type of sexual asymmetry,
which is then reflected in the asymmetric inheritance of cytoplasmic markers.
An example given is the case of different migration rates in males and females;
simulations using 2, 3, 4, or 5 unlinked autosomal markers with a maternally inherited
cytoplasmic marker illustrate how nuclear-nuclear and cytonuclear associations
can be used to separately estimate female and male migration rates. The general
framework developed here allows us to investigate conditions where associations
between loci with different modes of inheritance are not equivalent and to use
this nonequivalence to test for deviations from simple models of admixture. '

text: 'We calculate the fixation probability of a beneficial allele that arises
as the result of a unique mutation in an asexual population that is subject to
recurrent deleterious mutation at rate U. Our analysis is an extension of previous
works, which make a biologically restrictive assumption that selection against
deleterious alleles is stronger than that on the beneficial allele of interest.
We show that when selection against deleterious alleles is weak, beneficial alleles
that confer a selective advantage that is small relative to U have greatly reduced
probabilities of fixation. We discuss the consequences of this effect for the
distribution of effects of alleles fixed during adaptation. We show that a selective
sweep will increase the fixation probabilities of other beneficial mutations arising
during some short interval afterward. We use the calculated fixation probabilities
to estimate the expected rate of fitness improvement in an asexual population
when beneficial alleles arise continually at some low rate proportional to U.
We estimate the rate of mutation that is optimal in the sense that it maximizes
this rate of fitness improvement. Again, this analysis relaxes the assumption
made previously that selection against deleterious alleles is stronger than on
beneficial alleles. '

text: Until recently, it was impracticable to identify the genes that are responsible
for variation in continuous traits, or to directly observe the effects of their
different alleles. Now, the abundance of genetic markers has made it possible
to identify quantitative trait loci (QTL) — the regions of a chromosome or, ideally,
individual sequence variants that are responsible for trait variation. What kind
of QTL do we expect to find and what can our observations of QTL tell us about
how organisms evolve? The key to understanding the evolutionary significance of
QTL is to understand the nature of inherited variation, not in the immediate mechanistic
sense of how genes influence phenotype, but, rather, to know what evolutionary
forces maintain genetic variability.

text: Natural populations are structured spatially into local populations and genetically
into diverse ‘genetic backgrounds’ defined by different combinations of selected
alleles. If selection maintains genetic backgrounds at constant frequency then
neutral diversity is enhanced. By contrast, if background frequencies fluctuate
then diversity is reduced. Provided that the population size of each background
is large enough, these effects can be described by the structured coalescent process.
Almost all the extant results based on the coalescent deal with a single selected
locus. Yet we know that very large numbers of genes are under selection and that
any substantial effects are likely to be due to the cumulative effects of many
loci. Here, we set up a general framework for the extension of the coalescent
to multilocus scenarios and we use it to study the simplest model, where strong
balancing selection acting on a set of n loci maintains 2n backgrounds at constant
frequencies and at linkage equilibrium. Analytical results show that the expected
linked neutral diversity increases exponentially with the number of selected loci
and can become extremely large. However, simulation results reveal that the structured
coalescent approach breaks down when the number of backgrounds approaches the
population size, because of stochastic fluctuations in background frequencies.
A new method is needed to extend the structured coalescent to cases with large
numbers of backgrounds.
