text: While sexual reproduction is widespread among many taxa, asexual lineages
have repeatedly evolved from sexual ancestors. Despite extensive research on the
evolution of sex, it is still unclear whether this switch represents a major transition
requiring major molecular reorganization, and how convergent the changes involved
are. In this study, we investigated the phylogenetic relationship and patterns
of gene expression of sexual and asexual lineages of Eurasian Artemia brine shrimp,
to assess how gene expression patterns are affected by the transition to asexuality.
We find only a few genes that are consistently associated with the evolution of
asexuality, suggesting that this shift may not require an extensive overhauling
of the meiotic machinery. While genes with sex-biased expression have high rates
of expression divergence within Eurasian Artemia, neither female- nor male-biased
genes appear to show unusual evolutionary patterns after sexuality is lost, contrary
to theoretical expectations.

text: Genes of the major histocompatibility complex (MHC) have been shown to influence
social signalling and mate preferences in many species, including humans. First
observations suggest that MHC signalling may also affect female fertility. To
test this hypothesis, we exposed 191 female horses (Equus caballus) to either
an MHC-similar or an MHC-dissimilar stimulus male around the time of ovulation
and conception. A within-subject experimental design controlled for non-MHC-linked
male characteristics, and instrumental insemination with semen of other males
(n = 106) controlled for potential confounding effects of semen or embryo characteristics.
We found that females were more likely to become pregnant if exposed to an MHC-dissimilar
than to an MHC-similar male, while overall genetic distance to the stimulus males
(based on microsatellite markers on 20 chromosomes) had no effect. Our results
demonstrate that early pregnancy failures can be due to maternal life-history
decisions (cryptic female choice) influenced by MHC-linked social signalling.

text: 'The fitness effects of symbionts on their hosts can be context-dependent,
with usually benign symbionts causing detrimental effects when their hosts are
stressed, or typically parasitic symbionts providing protection towards their
hosts (e.g. against pathogen infection). Here, we studied the novel association
between the invasive garden ant Lasius neglectus and its fungal ectosymbiont Laboulbenia
formicarum for potential costs and benefits. We tested ants with different Laboulbenia
levels for their survival and immunity under resource limitation and exposure
to the obligate killing entomopathogen Metarhizium brunneum. While survival of
L. neglectus workers under starvation was significantly decreased with increasing
Laboulbenia levels, host survival under Metarhizium exposure increased with higher
levels of the ectosymbiont, suggesting a symbiont-mediated anti-pathogen protection,
which seems to be driven mechanistically by both improved sanitary behaviours
and an upregulated immune system. Ants with high Laboulbenia levels showed significantly
longer self-grooming and elevated expression of immune genes relevant for wound
repair and antifungal responses (β-1,3-glucan binding protein, Prophenoloxidase),
compared with ants carrying low Laboulbenia levels. This suggests that the ectosymbiont
Laboulbenia formicarum weakens its ant host by either direct resource exploitation
or the costs of an upregulated behavioural and immunological response, which,
however, provides a prophylactic protection upon later exposure to pathogens. '

text: Phenotypes expressed in a social context are not only a function of the individual,
but can also be shaped by the phenotypes of social partners. These social effects
may play a major role in the evolution of cooperative breeding if social partners
differ in the quality of care they provide and if individual carers adjust their
effort in relation to that of other carers. When applying social effects models
to wild study systems, it is also important to explore sources of individual plasticity
that could masquerade as social effects. We studied offspring provisioning rates
of parents and helpers in a wild population of long-tailed tits Aegithalos caudatus
using a quantitative genetic framework to identify these social effects and partition
them into genetic, permanent environment and current environment components. Controlling
for other effects, individuals were consistent in their provisioning effort at
a given nest, but adjusted their effort based on who was in their social group,
indicating the presence of social effects. However, these social effects differed
between years and social contexts, indicating a current environment effect, rather
than indicating a genetic or permanent environment effect. While this study reveals
the importance of examining environmental and genetic sources of social effects,
the framework we present is entirely general, enabling a greater understanding
of potentially important social effects within any ecological population.

text: Hamilton's concept of local mate competition (LMC) is the standard model to
explain female-biased sex ratios in solitary Hymenoptera. In social Hymenoptera,
however, LMC has remained controversial, mainly because manipulation of sex allocation
by workers in response to relatedness asymmetries is an additional powerful mechanism
of female bias. Furthermore, the predominant mating systems in the social insects
are thought to make LMC unlikely. Nevertheless, several species exist in which
dispersal of males is limited and mating occurs in the nest. Some of these species,
such as the ant Cardiocondyla obscurior, have evolved dimorphic males, with one
morph being specialized for dispersal and the other for fighting with nest-mate
males over access to females. Such life history, combining sociality and alternative
reproductive tactics in males, provides a unique opportunity to test the power
of LMC as a selective force leading to female-biased sex ratios in social Hymenoptera.
We show that, in concordance with LMC predictions, an experimental increase in
queen number leads to a shift in sex allocation in favour of non-dispersing males,
but does not influence the proportion of disperser males. Furthermore, we can
assign this change in sex allocation at the colony level to the queens and rule
out worker manipulation.

text: We measured the heterozygous effects on net fitness of a sample of 12 wild-type
third chromosomes in D. melanogaster. Effects on fitness were assessed by competing
the wild-type chromosomes against balancer chromosomes, to prevent the production
of recombinants. The measurements were carried out in the population cage environment
in which the life history had been evolving, in an undisturbed population with
overlapping generations, and replicated measurements were made on each chromosome
to control for confounding effects such as mutation accumulation. We found significant
variation among the wild type chromosomes in their additive genetic effect on
net fitness. The system provides an opportunity to obtain an accurate estimate
of the distribution of heterozygous effects on net fitness, the contribution of
different fitness components including male mating success, and the role of intra-chromosomal
epistasis in fitness variation.

text: 'Hybridizing taxa remain distinct for two main reasons. Natural selection
acts against hybrids either because of their incompatible genome, or because of
differential adaptation of the pure types across an environmental gradient. Here,
we provide experimental evidence that the location of the Bombina (Anura: Discoglossidae)
hybrid zone in Croatia is, at least in part, determined by differential adaptation.
B. bombina typically breeds in permanent water in the lowland, whereas B. variegata
reproduces in puddles at higher elevations. In a reciprocal translocation, pure
bombina and variegata tadpoles were introduced in equal proportions into lowland
pond enclosures and upland puddles. After three weeks, variegata exceeded bombina
in survival and growth in both habitats. The effect was most pronounced in puddles,
where the few surviving bombina tadpoles had hardly grown at all. In comparison
to variegata, the smaller hatchlings of bombina grew relatively faster in ponds,
but remained smaller in absolute terms. Nevertheless, B. bombina appears better
adapted to ponds than to puddles. The mechanisms by which variegata is excluded
from ponds remain to be demonstrated. These data show that habitat dependent selection
prevents the invasion of bombina tadpole traits into the variegata gene pool.
Given the strong linkage disequilibria in hybrid populations, differential selection
on tadpoles may be sufficient to maintain the integrity of the two gene pools.'
