title: Data from: Oxidative stress and the evolution of sex differences in lifespan and ageing in the decorated cricket, Gryllodes sigillatus

description: The Free Radical Theory of Ageing (FRTA) predicts that oxidative stress,
 induced when levels of reactive oxygen species exceed the capacity of
 antioxidant defences, causes ageing. Recently, it has also been argued
 that oxidative damage may mediate important life-history trade-offs. Here,
 we use inbred lines of the decorated cricket, Gryllodes sigillatus, to
 estimate the genetic (co)variance between age-dependent reproductive
 effort, lifespan, ageing, oxidative damage and total antioxidant capacity
 within and between the sexes. The FRTA predicts that oxidative damage
 should accumulate with age and negatively correlate with lifespan. We find
 that protein oxidation is greater in the shorter lived sex (females) and
 negatively genetically correlated with lifespan in both sexes. However,
 oxidative damage did not accumulate with age in either sex. Previously we
 have shown antagonistic pleiotropy between the genes for early life
 reproductive effort and ageing rate in both sexes, although this was
 stronger in females. In females, we find that elevated fecundity early in
 life is associated with greater protein oxidation later in life, which is
 in turn positively correlated with the rate of ageing. Our results provide
 mixed support for the FRTA but suggest that oxidative stress may mediate
 sex-specific life-history strategies in G. sigillatus.

title: Data from: Vitamins, stress and growth: the availability of antioxidants in early life influences the expression of cryptic genetic variation

description: Environmental inputs during early development can shape the expression of
 phenotypes, which has long-lasting consequences in physiology and life
 history of an organism. Here, we study whether experimentally manipulated
 availability of dietary antioxidants, vitamins C and E, influences the
 expression of genetic variance for antioxidant defence, endocrine signal
 and body mass in yellow-legged gull chicks using quantitative genetic
 models based on full siblings. Our experimental study in a natural
 population reveals that the expression of genetic variance in total
 antioxidant capacity in plasma increased in chicks supplemented with
 vitamins C and E despite the negligible effects on the average phenotype.
 This suggests that individuals differ in their ability to capture and
 transport dietary antioxidants or to respond to these extra resources, and
 importantly, this ability has a genetic basis. Corticosterone level in
 plasma and body mass were negatively correlated at the phenotypic level.
 Significant genetic variance of corticosterone level appeared only in
 control chicks nonsupplemented with vitamins, suggesting that the genetic
 variation of endocrine system, which transmits environmental cues to
 adaptively control chick development, appeared in stressful conditions
 (i.e. poor antioxidant availability). Therefore, environmental inputs may
 shape evolutionary trajectories of antioxidant capacity and endocrine
 system by affecting the expression of cryptic genetic variation.

title: Data from: Multiple host-shifts by the emerging honeybee parasite, Varroa jacobsoni

description: Host shifts are a key mechanism of parasite evolution and responsible for
 the emergence of many economically important pathogens. Varroa destructor
 has been a major factor in global honeybee (Apis mellifera) declines since
 shifting hosts from the Asian honeybee (Apis cerana) &gt; 50 years
 ago. Until recently, only two haplotypes of V. destructor (Korea and
 Japan) had successfully host shifted to A. mellifera. In 2008, the sister
 species V. jacobsoni was found for the first time parasitizing A.
 mellifera in Papua New Guinea (PNG). This recent host shift presents a
 serious threat to world apiculture but also provides the opportunity to
 examine host shifting in this system. We used 12 microsatellites to
 compare genetic variation of V. jacobsoni on A. mellifera in PNG with
 mites on A. cerana in both PNG and surrounding regions. We identified two
 distinct lineages of V. jacobsoni reproducing on A. mellifera in PNG. Our
 analysis indicated independent host shift events have occurred through
 small numbers of mites shifting from local A. cerana populations.
 Additional lineages were found in the neighbouring Papua and Solomon
 Islands that had partially host shifted to A. mellifera, that is producing
 immature offspring on drone brood only. These mites were likely in
 transition to full colonization of A. mellifera. Significant population
 structure between mites on the different hosts suggested host shifted V.
 jacobsoni populations may not still reproduce on A. cerana, although
 limited gene flow may exist. Our studies provide further insight into
 parasite host shift evolution and help characterize this new Varroa mite
 threat to A. mellifera worldwide.

title: Data from: Fire does not strongly affect genetic diversity or structure of a common treefrog in the endangered Florida scrub

description: Fire regimes influence natural populations of organisms in diverse ways,
 via direct effects on population dynamics as well as indirect effects on
 habitat and ecosystem processes. Although many amphibian species have
 evolved to persist in fire-dependent ecosystems, the effects of fire on
 the genetic diversity of amphibian populations remain relatively
 unexplored. We examined how different aspects of fire history relate to
 population genetic diversity and structure of an abundant anuran, Hyla
 femoralis, in a large, intact area of Florida scrub containing hundreds of
 seasonally inundated ponds. Specifically, we assessed the overall
 population genetic structure and examined whether variation in time since
 fire, fire intensity, or historical fire frequency at breeding sites
 explained spatial variation in genetic diversity. Based on our sampling of
 17 breeding aggregations within the 2,100-ha study area, neither recent
 nor frequent fire reduce genetic diversity or restrict connectivity among
 ponds for H. femoralis. Overall, mean effective population sizes were
 large (average range = 68–572). We detected a positive trend between
 effective population size (Ne) and average intensity of the most-recent
 fire, with this factor explaining 42% of the variation in Ne. Our results
 contrast with previous studies that consistently demonstrate strong
 relationships between fire history and population genetic structure of
 scrub-associated lizard species, suggesting that H. femoralis is resilient
 to a wide range of fire regimes. More generally, our study contributes to
 understanding the roles of life-history characteristics and environmental
 unpredictability in shaping organisms’ responses to fire.

title: Data from: Across-year social stability shapes network structure in wintering migrant sparrows

description: Migratory birds often form flocks on their wintering grounds, but
 important details of social structure such as the patterns of association
 between individuals are virtually unknown. We analysed networks of
 co-membership in short-term flocks for wintering golden-crowned sparrows
 (Zonotrichia atricapilla) across three years and discovered social
 complexity unsuspected for migratory songbirds. The population was
 consistently clustered into distinct social communities within a
 relatively small area (~ 7 ha). Birds returned to the same community
 across years, with mortality and recruitment leading to some degree of
 turnover in membership. These spatiotemporal patterns were explained by
 the combination of space use and social preference – birds that flocked
 together in one year flocked together again in the subsequent year more
 often than were expected based on degrees of home range overlap. Our
 results suggest that a surprising level of social fidelity across years
 leads to repeatable patterns of social network structure in migratory
 populations.

 Sphaerobothris aghababiani Volkovitsh et Kalashian, 1998 – 2n=16 (14+Xyp)
 were studied using conventional staining and different chromosome banding
 techniques: C-banding, AgNOR-banding, as well as fluorochrome Chromomycin
 A3 (CMA3) and DAPI. It is shown that C-positive segments are weakly
 visible in all four species which indicates a small amount of constitutive
 heterochromatin (CH). There were no signals after DAPI staining and some
 positive signals were discovered using CMA3 staining demonstrating absence
 of AT-rich DNA and presence of GC-rich clusters of CH. Nucleolus
 organizing regions (NORs) were revealed using Ag-NOR technique;
 argentophilic material mostly coincides with positive signals obtained
 using CMA3 staining.

title: Data from: Pollen competition between morphs in a pollen-color dimorphic herb and the loss of phenotypic polymorphism within populations

description: Flower color polymorphism is relatively uncommon in natural flowering
 plants, suggesting that maintenance of different color morphs within
 populations is difficult. To address the selective mechanisms shaping
 pollen-color dimorphism, pollinator preferences and reproductive
 performance were studied over three years in Epimedium pubescens in which
 some populations had plants with either green or yellow pollen (and
 anthers). Visitation rate and pollen removal and receipt by the bee
 pollinator (Andrena emeishanica) did not differ between the two color
 morphs. Compared to the green morph, siring success of the yellow morph’s
 pollen was lower, but that of mixtures of pollen from green and yellow
 morphs was lowest. This difference, corresponding to in and ex vivo
 experiments on pollen performance, indicated that pollen germination,
 rather than tube growth, of the green morph was higher than that of the
 yellow morph and was seriously constrained in both morphs if a pollen
 competitor was present. A rare green morph may invade a yellow-morph
 population, but the co-existence of pollen color variants is complicated
 by the reduced siring success of mixed pollinations. Potential pollen
 competition between morphs may have discouraged the maintenance of
 multiple phenotypes within populations, a cryptic mechanism of competitive
 exclusion.

title: Data from: Fitness costs of herbicide resistance across natural populations of the common morning glory, Ipomoea purpurea

description: Although fitness costs associated with plant defensive traits are widely
 expected, they are not universally detected, calling into question their
 generality. Here we examine the potential for life history trade-offs
 associated with herbicide resistance by examining seed germination, root
 growth, and above-ground growth across 43 naturally occurring populations
 of Ipomoea purpurea that vary in their resistance to RoundUp®, the most
 commonly used herbicide worldwide. We find evidence for life history
 trade-offs associated with all three traits; highly resistant populations
 had lower germination, shorter roots and smaller above-ground size. A
 visual exploration of the data indicated that the type of trade-off may
 differ among populations. Our results demonstrate that costs of adaptation
 may be present at stages other than simply the production of progeny in
 this agricultural weed. Additionally, the cumulative effect of costs at
 multiple life cycle stages can result in severe consequences to fitness
 when adapting to novel environments.

title: Data from: Exploring neutral and adaptive processes in expanding populations of gilthead sea bream, Sparus aurata L., in the North-East Atlantic

description: Recent studies in empirical population genetics have highlighted the
 importance of taking into account both neutral and adaptive genetic
 variation in characterizing microevolutionary dynamics. Here we explore
 the genetic population structure and the footprints of selection in four
 populations of the warm-temperate coastal fish, the gilthead sea bream
 (Sparus aurata), whose recent northward expansion has been linked to
 climate change. Samples were collected at four Atlantic locations,
 including Spain, Portugal, France and the South of Ireland, and
 genetically assayed using a suite of species-specific markers, including
 15 putatively neutral microsatellites and 23 Expressed Sequence Tag-linked
 (ESTs) markers, as well as a portion of the mitochondrial DNA (mtDNA)
 Control Region. Two of the putatively neutral markers, Bld-10 and Ad-10,
 bore signatures of strong directional selection, particularly in the newly
 established Irish population, though the potential 'surfing
 effect' of rare alleles at the edge of the expansion front was also
 considered. Analyses after the removal of these loci suggest low but
 significant population structure likely affected by some degree of gene
 flow counteracting random genetic drift. No signal of historic divergence
 was detected at mtDNA. BLAST searches conducted with all 38 markers used
 failed to identify specific genomic regions associated to adaptive
 functions. However, the availability of genomic resources for this
 commercially valuable species is rapidly increasing, bringing us closer to
 the understanding of the interplay between selective and neutral
 evolutionary forces, shaping population divergence of an expanding species
 in a heterogeneous milieu.

title: Data from: Testing the reproductive groundplan hypothesis in ants (Hymenoptera: Formicidae)

description: The evolution of complex societies with obligate reproductive division of
 labour represents one of the major transitions in evolution. In such
 societies, functionally sterile individuals (workers) perform many of
 fitness-relevant behaviours including allomaternal ones, without getting
 any direct fitness benefits. The question of how such worker division of
 labour has evolved remains controversial. The reproductive groundplan
 hypothesis (RGPH) offers a powerful proximate explanation for this
 evolutionary leap. The RGPH argues that the conserved genetic and
 endocrinological networks regulating fitness relevant behaviour (e g.
 foraging and brood care) in their solitary ancestors have become decoupled
 from actual reproduction in the worker caste and now generate worker
 behavioural phenotypes. However, the empirical support for this hypothesis
 remains limited to a handful of species making its general validity
 uncertain. In this study we combine data from the literature with targeted
 sampling of key species and apply phylogenetically controlled comparative
 analysis to investigate if the key prediction of the RGPH, namely an
 association between allomaternal behaviour and a allomaternal
 physiological state holds in the largest and most species-rich clade of
 social insects, the ants. Our findings clearly support the RPGH as a
 general framework to understand the evolution of the worker caste and shed
 light on one of the major transition in evolutionary history.

title: Data from: Population genetic structure, genetic diversity, and natural history of the South American species of Nothofagus Subgenus Lophozonia (Nothofagaceae) inferred from nuclear microsatellite data

description: The effect of glaciation on levels and patterns of genetic variation has
 been well studied in the Northern Hemisphere. However, although glaciation
 has undoubtedly shaped the genetic structure of plants in the Southern
 Hemisphere, fewer studies have characterized the effect, and almost none
 of them using microsatellites. Particularly complex patterns of genetic
 structure might be expected in areas such as the Andes, where both
 latitudinal and altitudinal glacial advance and retreat have molded modern
 plant communities. We therefore studied the population genetics of three
 closely related, hybridizing species of Nothofagus (N. obliqua, N. alpina,
 and N. glauca, all of subgenus Lophozonia; Nothofagaceae) from Chile. To
 estimate population genetic parameters and infer the influence of the last
 ice age on the spatial and genetic distribution of these species, we
 examined and analyzed genetic variability at seven polymorphic
 microsatellite DNA loci in 640 individuals from 40 populations covering
 most of the ranges of these species in Chile. Populations showed no
 significant inbreeding and exhibited relatively high levels of genetic
 diversity (HE=0.502-0.662) and slight, but significant, genetic structure
 (RST=8.7-16.0%). However, in N. obliqua, the small amount of genetic
 structure was spatially organized into three well-defined latitudinal
 groups. Our data may also suggest some introgression of N. alpina genes
 into N. obliqua in the northern populations. These results allowed us to
 reconstruct the influence of the last ice age on the genetic structure of
 these species, suggesting several centers of genetic diversity for N.
 obliqua and N. alpina, in agreement with the multiple refugia hypothesis.

title: Data from: Evidence that fertility trades off with early offspring fitness as males age

description: Models of aging predict that sperm function and fertility should decline
 with age as sperm are exposed to free radical damage and mutation
 accumulation. However, theory also suggests that mating with older males
 should be beneficial for females because survival to old age is a
 demonstration of a male’s high genetic and/or phenotypic quality.
 Consequently, declines in sperm fitness may be offset by indirect fitness
 benefits exhibited in offspring. While numerous studies have investigated
 age-based declines in male fertility, none has taken the integrated
 approach of studying age-based effects on both male fertility and
 offspring fitness. Here, using a cohort-based longitudinal study of
 zebrafish (Danio rerio), we report a decline in male mating success and
 fertility with male age but also compensating indirect benefits. Using in
 vitro fertilisation, we show that offspring from older males exhibit
 superior early survival compared to those from their youngest
 counterparts. These findings suggest that the high offspring fitness
 observed for the subset of males that survive to an old age (~51 % in this
 study) may represent compensating benefits for declining fertility with
 age, thus challenging widely held views about the fitness costs of mating
 with older males.

title: Data from: Differential visual ornamentation between brood-parasitic and parental cuckoos

description: The evolution of brood parasitism should affect adult phenotypic traits
 due to sexual selection as well as the parasite-host interactions, though
 it is rarely focused on. Sexual selection theory predicts extravagant
 secondary sexual characteristics in brood parasites while immature-like
 modest sexual characteristics in parental species. This is because
 juvenile-like immature traits can attract mates by exploiting parental
 care for young (i.e. attraction to young), and because the good parent
 process, which favors traits that signal parental care ability, would
 constrain the evolution of costly secondary sexual characteristics due to
 evolutionary tradeoffs between parental investment and sexually selected
 traits. Using a phylogenetic comparative approach, we studied plumage and
 bare-part characteristics of adults in relation to brood parasitism in
 cuckoos (family Cuculidae), in which brood parasitism together with loss
 of parental care has evolved three times. As predicted, we found that
 non-parasitic cuckoos had plumage more similar to the juveniles than did
 brood parasitic cuckoos. Furthermore, non-parasitic cuckoos had a higher
 probability of having additional bare skin, i.e. a seemingly less-costly,
 hatchling-like trait, than did brood parasitic cuckoos. This finding
 further supports the link between parental care and sexual selection,
 although the influence of a parasite-host interaction cannot be excluded.
 The analysis of evolutionary pathways suggested inter-dependent evolution
 of additional bare skin and brood parasitism. Brood parasitism together
 with the loss of parental care may facilitate the maintenance of a modest
 phenotype similar to the young, and vice versa in some cases.
