title: Data from: Divergent artificial selection for female reproductive investment has a sexually concordant effect on male reproductive success

description: Depending on the genetic architecture of male and female fitness,
 sex-specific selection can have negative, positive or neutral consequences
 for the opposite sex. Theory predicts that conflict between male and
 female function may drive the breakdown of intrasexual genetic
 correlations, allowing sexual dimorphism in sexually antagonistic traits.
 Reproductive traits are the epitome of this, showing highly differentiated
 proximate functions between the sexes. Here we use divergent artificial
 selection lines for female reproductive investment to test how
 female-specific selection on a sex-limited trait affects male reproductive
 success in a precocial bird, the Japanese quail (Coturnix japonica). We
 demonstrate that selection for increased egg investment in females
 positively affects male reproductive success both in competitive and
 non-competitive mating situations. This increased reproductive success was
 linked to a relatively larger left testis in males originating from lines
 selected for high female reproductive investment. Given that female quail
 have functional gonads only on their left side, this correlated response
 indicates that selection has acted on the shared developmental basis of
 male and female gonads. Our study thereby provides evidence for a positive
 genetic correlation between key reproductive traits in males and females
 despite a high degree of sexual dimorphism, and suggests that, in this
 system, selection on reproductive function is sexually concordant.

title: Data from: Genotypic and phenotypic variation in transmission traits of a complex life cycle parasite

description: Characterizing genetic variation in parasite transmission traits and its
 contribution to parasite vigor is essential for understanding the
 evolution of parasite life-history traits. We measured genetic variation
 in output, activity, survival, and infection success of clonal
 transmission stages (cercaria larvae) of a complex life cycle parasite
 (Diplostomum pseudospathaceum). We further tested if variation in host
 nutritional stage had an effect on these traits by keeping hosts on
 limited or ad libitum diet. The traits we measured were highly variable
 among parasite genotypes indicating significant genetic variation in these
 life-history traits. Traits were also phenotypically variable, for
 example, there was significant variation in the measured traits over time
 within each genotype. However, host nutritional stage had no effect on the
 parasite traits suggesting that a short-term reduction in host resources
 was not limiting the cercarial output or performance. Overall, these
 results suggest significant interclonal and phenotypic variation in
 parasite transmission traits that are not affected by host nutritional
 status.

title: Data from: Female-induced remote regulation of sperm physiology may provide opportunities for gamete-level mate choice

description: In sedentary externally fertilizing species, direct interactions between
 mating partners are limited and pre-fertilization communication between
 sexes occur largely at the gamete level. Certain combinations of eggs and
 sperm often have higher fertilization success than others, which may be
 contingent on egg-derived chemical factors that preferentially attract
 sperm from compatible males. Here, we examine the mechanisms underlying
 such effects in the marine mussel Mytilus galloprovincialis, where
 differential sperm attraction has recently been shown to be associated
 with variation in offspring viability. Specifically, we focus on the sperm
 surface glycans, an individually unique layer of carbohydrates that
 moderate self-recognition and other cellular-level interactions. In many
 species egg-derived factors trigger remarkable changes in the sperm’s
 glycan layer, physiology and swimming behavior, and thus potentially
 moderate mate choice at the gamete level. Here we show that sperm glycan
 modifications and the strength of acrosome reaction are both dependent on
 specific male-female interactions (male-female combination). We also find
 associations between female-induced sperm glycan changes and the Ca2+
 influx into sperm – a key regulator of fertilization processes from sperm
 capacitation to gamete fusion. Together, our results suggest that
 female-induced remote regulation of sperm physiology may constitute a
 novel mechanism of gamete-level mate choice.

title: Data from: Crossing the divide: gene flow produces intergeneric hybrid in feral transgenic creeping bentgrass population

description: Gene flow is the most frequently expressed public concern related to the
 deregulation of transgenic events (Snow 2002; Ellstrand 2003). However,
 assessing the potential for transgene escape is complex because it depends
 on the opportunities for unintended gene flow, and establishment and
 persistence of the transgene in the environment (Warwick et al. 2008).
 Creeping bentgrass (Agrostis stolonifera L.), a turfgrass species widely
 used on golf courses, has been genetically engineered to be resistant to
 glyphosate, a nonselective herbicide. Outcrossing species, such as
 creeping bentgrass (CB), which have several compatible species, have
 greater chances for gene escape and spontaneous hybridization (i.e.
 natural, unassisted sexual reproduction between taxa in the field), which
 challenges transgene containment. Several authors have emphasized the need
 for evidence of spontaneous hybridization to infer the potential for gene
 flow (Armstrong et al. 2005). Here we report that a transgenic
 intergeneric hybrid has been produced as result of spontaneous
 hybridization of a feral-regulated transgenic pollen receptor (CB) and a
 nontransgenic pollen donor (rabbitfoot grass, RF, Polypogon monspeliensis
 (L.) Desf.). We identified an off-type transgenic seedling and confirmed
 it to be CB × RF intergeneric hybrid. This first report of a transgenic
 intergeneric hybrid produced in situ with a regulated transgenic event
 demonstrates the importance of considering all possible avenues for
 transgene spread at the landscape level before planting a regulated
 transgenic crop in the field. Spontaneous hybridization adds a level of
 complexity to transgene monitoring, containment, mitigation and
 remediation programmes.

title: Data from: Experimental evolution of bet hedging under manipulated environmental uncertainty in Neurospora crassa

description: All organisms are faced with environmental uncertainty. Bet-hedging theory
 expects unpredictable selection to result in the evolution of traits that
 maximize the geometric-mean fitness even though such traits appear to be
 detrimental over the shorter term. Despite the centrality of fitness
 measures to evolutionary analysis, no direct test of the geometric-mean
 fitness principle exists. Here, we directly distinguish between
 predictions of competing fitness maximization principles by testing
 Cohen's 1966 classic bet-hedging model using the fungus Neurospora
 crassa. The simple prediction is that propagule dormancy will evolve in
 proportion to the frequency of ‘bad’ years, whereas the prediction of the
 alternative arithmetic-mean principle is the evolution of zero dormancy as
 long as the expectation of a bad year is less than 0.5. Ascospore dormancy
 fraction in N. crassa was allowed to evolve under five experimental
 selection regimes that differed in the frequency of unpredictable ‘bad
 years’. Results were consistent with bet-hedging theory: final dormancy
 fraction in 12 genetic lineages across 88 independently evolving samples
 was proportional to the frequency of bad years, and evolved both upwards
 and downwards as predicted from a range of starting dormancy fractions.
 These findings suggest that selection results in adaptation to variable
 rather than to expected environments.

title: Data from: Females mate with males with diminished pheomelanin-based coloration in the Eurasian nuthatch Sitta europaea

description: Sexual selection can drive the evolution of phenotypic traits because of
 female preferences for exaggerated trait expression in males. Sexual
 selection can also lead to the evolutionary loss of traits, a process to
 which female preferences for diminished male trait expression are
 hypothesized to contribute. However, empirical evidence of female
 preferences for diminished male traits is virtually lacking. Eurasian
 nuthatches Sitta europaea provide an opportunity to test this possibility,
 as a chestnut flank patch produced by the pigment pheomelanin is present
 since the first plumage of these birds and its color is more intense in
 nestlings in poor condition in our study population. It has been proposed
 that developing birds in poor condition may increase their production of
 pheomelanin as a detoxifying strategy. Female nuthatches may thus prefer
 mating with males showing flank feathers of diminished color, as this
 could indicate that males experienced good conditions early in
 development, which can positively affect the fitness of future
 generations. Here we show results according with this prediction in a wild
 population of Eurasian nuthatches, as adult males with lighter chestnut
 feathers paired earlier in the season, while chestnut coloration had no
 effect on female mating success. Chestnut color expression was not
 affected by the body condition of birds, suggesting that females obtain
 information on the body condition in early life of their potential mates
 and not on their current body condition. This constitutes one of the few
 examples of females mating with males showing diminished traits and
 provides the only explanation so far by which this process can occur.

title: Data from: Harvesting effects on wild bee communities in bioenergy grasslands depend on nesting guild

description: Conversion of annual crops to native perennial grasslands for bioenergy
 production may help conserve wild bees by enhancing nest and food
 resources. However, bee response to the disturbance of biomass harvesting
 may depend on their nesting location, thus their vulnerability to nest
 destruction, and the response of the forb community on which they forage.
 Moreover, because bees have long foraging ranges, effects of local
 harvesting may depend on the amount of natural habitat in the surrounding
 landscape. We performed a large-scale one- and two-year experiment in
 Michigan and Wisconsin, USA, respectively, to examine how grassland
 harvesting, landscape context, and study year affect the forb community,
 above- and belowground-nesting bee species richness, community
 composition, trap nest emergence, and visitation rate. In Wisconsin,
 harvesting increased forb richness, cover, and evenness compared to
 unharvested control sites. Harvesting negatively affected
 aboveground-nesting bee richness and emergence from trap nests, possibly
 because of nest destruction during the previous harvest. By contrast,
 harvesting positively affected belowground-nesting bee richness, possibly
 because of the greater food resource availability and reduced thatch
 allowing greater access to nesting sites in the soil. Harvesting also
 affected bee community composition, reflecting the increase in
 belowground-nesting species at harvested sites. Despite harvesting effects
 on forb and bee communities, there was no effect on flower visitation
 rate, indicating little effect on pollination function. We did not find a
 harvest by landscape context interaction, which, in combination with the
 negative harvesting effect on trap nest emergence, suggests that
 harvesting can affect local population growth rather than simply affecting
 forager aggregation in different resource environments. For bees, there
 was no harvest by study year interaction, indicating a consistent response
 over a short timescale. Similarly, in Michigan, belowground-nesting
 species also responded positively to harvesting, which was more pronounced
 in sandier soils that are preferred for nesting. However, other components
 of the Michigan bee and forb communities were not significantly affected
 by biomass harvesting. Overall, our study demonstrates that harvesting
 grasslands can positively affect the 80% of bee species that nest
 belowground by enhancing nest and/or forage resources, but that conserving
 aboveground-nesters may require leaving some area unharvested.

title: Data from: Co-feeding intra- and interspecific transmission of an emerging insect-borne rickettsial pathogen

description: Cat fleas (Ctenocephalides felis) are known as the primary vector and
 reservoir of Rickettsia felis, the causative agent of flea-borne spotted
 fever; however, field surveys regularly report molecular detection of this
 infectious agent from other blood-feeding arthropods. The presence of R.
 felis in additional arthropods may be the result of chance consumption of
 an infectious bloodmeal, but isolation of viable rickettsiae circulating
 in the blood of suspected vertebrate reservoirs has not been demonstrated.
 Successful transmission of pathogens between actively blood-feeding
 arthropods in the absence of a disseminated vertebrate infection has been
 verified, referred to as cofeeding transmission. Therefore, the principal
 route from systemically infected vertebrates to uninfected arthropods may
 not be applicable to the R. felis transmission cycle. Here, we show both
 intra- and interspecific transmission of R. felis between cofeeding
 arthropods on a vertebrate host. Analyses revealed that infected cat fleas
 transmitted R. felis to naïve cat fleas and rat fleas (Xenopsylla cheopis)
 via fleabite on a nonrickettsemic vertebrate host. Also, cat fleas
 infected by cofeeding were infectious to newly emerged uninfected cat
 fleas in an artificial system. Furthermore, we utilized a stochastic model
 to demonstrate that cofeeding is sufficient to explain the enzootic spread
 of R. felis amongst populations of the biological vector. Our results
 implicate cat fleas in the spread of R. felis amongst different vectors,
 and the demonstration of cofeeding transmission of R. felis through a
 vertebrate host represents a novel transmission paradigm for insect-borne
 Rickettsia and furthers our understanding of this emerging rickettsiosis.

title: Data from: Delayed dispersal and the costs and benefits of different routes to independent breeding in a cooperatively breeding bird

description: Why sexually mature individuals stay in groups as nonreproductive
 subordinates is central to the evolution of sociality and cooperative
 breeding. To understand such delayed dispersal, its costs and benefits
 need to be compared with those of permanently leaving to float through the
 population. However, comprehensive comparisons, especially regarding
 differences in future breeding opportunities, are rare. Moreover,
 extraterritorial prospecting by philopatric individuals has generally been
 ignored, even though the factors underlying this route to independent
 breeding may differ from those of strict philopatry or floating. We use a
 comprehensive predictive framework to explore how various costs, benefits
 and intrinsic, environmental and social factors explain philopatry,
 prospecting, and floating in Seychelles warblers (Acrocephalus
 sechellensis). Not only floaters more likely obtained an independent
 breeding position before the next season than strictly philopatric
 individuals, but also suffered higher mortality. Prospecting yielded
 similar benefits to floating but lower mortality costs, suggesting that it
 is overall more beneficial than floating and strict philopatry. While
 prospecting is probably individual-driven, although limited by resource
 availability, floating likely results from eviction by unrelated breeders.
 Such differences in proximate and ultimate factors underlying each route
 to independent breeding highlight the need for simultaneous consideration
 when studying the evolution of delayed dispersal.

title: Data from: Intracellular glucocorticoid receptors in spleen, but not skin, vary seasonally in wild house sparrows (Passer domesticus)

description: Over the short-term and at physiological doses, acute increases in
 corticosterone (CORT) titres can enhance immune function. There are
 predictable seasonal patterns in both circulating CORT and immune function
 across many animal species, but whether CORT receptor density in immune
 tissues varies seasonally is currently unknown. Using radioligand binding
 assays, we examined changes in concentrations of glucocorticoid receptors
 (GR) and mineralocorticoid receptors (MR) in spleen and skin in
 wild-caught house sparrows in Massachusetts during six different
 life-history stages: moult, early winter, late winter, pre-egg-laying,
 breeding and late breeding. Splenic GR and MR binding were highest during
 the pre-laying period. This may help animals respond to immune threats
 through increased lymphocyte proliferation and/or an increase in
 delayed-type hypersensitivity reactions, both of which CORT can stimulate
 and in which spleen is involved. A decrease in splenic GR and MR during
 the late breeding period coincides with low baseline and stress-induced
 CORT, suggesting immune function in spleen may be relatively
 CORT-independent during this period. We saw no seasonal patterns in GR or
 MR in skin, suggesting skin's response to CORT is modulated primarily
 via changes in circulating CORT titres and/or via local production of CORT
 in response to wounding and other noxious stimuli.
