title: Data from: No inbreeding depression but increased sexual investment in highly inbred ant colonies

description: Inbreeding can lead to the expression of deleterious recessive alleles and
 to a subsequent fitness reduction. In Hymenoptera, deleterious alleles are
 purged in haploid males moderating inbreeding costs. However, in these
 haplo-diploid species, inbreeding can result in the production of sterile
 diploid males. We investigated the effects of inbreeding on the individual
 and colony level in field colonies of the highly inbred ant Hypoponera
 opacior. In this species, outbreeding winged sexuals and nest-mating
 wingless sexuals mate during two separate reproductive periods. We show
 that regular sib-matings lead to high levels of homozygosity and the
 occasional production of diploid males, which sporadically sire triploid
 offspring. On the individual level, inbreeding was associated with an
 increased body size in workers. On the colony level, we found no evidence
 for inbreeding depression as productivity was unaffected by the level of
 homozygosity. Instead, inbred colonies altered their allocation strategies
 by investing more resources into sexuals than into workers. This shift
 towards sexual production was due to an increased investment in both males
 and queens, which was particularly pronounced in the dispersive
 generation. The absence of inbreeding depression combined with increased
 reproductive investment, especially in outbreeding sexuals, suggest that
 these ants have evolved active strategies to regulate the extent and
 effects of frequent inbreeding.

title: Data from: Elevating perceived predation risk modifies the relationship between parental effort and song complexity in the song sparrow (Melospiza melodia)

description: Adult-directed predation risk elevates costs of parental care, and may
 modify relationships between sexually selected ornaments and parental
 effort by accentuating the tradeoff between survival and parental
 investment. We assessed multiple hypotheses regarding the relationship
 between maternal effort, paternal effort, and the sexually selected trait
 of male song complexity in the song sparrow Melospiza melodia. Further, we
 explored whether experimentally elevating perceived adult-directed
 predation risk near nests affected these relationships. We quantified two
 dimensions of song complexity: song repertoire size and residual syllable
 number (the relative number of syllables for a given song repertoire
 size). Under elevated perceived predation risk, but not in the absence of
 the predator stimuli, females mated to males with higher residual syllable
 number displayed higher nestling provisioning rates and performed a
 greater proportion of nestling provisioning trips. In other words,
 elevating perceived predation risk induced a pattern of maternal
 investment consistent with differential allocation. In contrast, under
 elevated perceived predation risk, only, females performed a lesser
 proportion of provisioning trips when mated to males with large song
 repertoire sizes. Further, consistent with the good parent hypothesis,
 males with large song repertoire sizes displayed lower latencies to return
 to the nest, independent of the predator stimuli. Results suggest that
 residual syllable number may reflect some aspect of male genetic quality,
 such that females are more willing to maintain maternal effort while
 facing heightened predation risk. On the other hand, females may gain
 paternal benefits when mated to males with large song repertoires. Our
 study supports the hypothesis that increased costs of parental care
 associated with predation risk may induce relationships between sexually
 selected traits and parental behavior, which may increase the strength of
 sexual selection. Additionally, results suggest that different aspects of
 song complexity may fulfill non-equivalent signaling roles.

title: Data from: Consequences of frugivore-mediated seed dispersal for the spatial and genetic structures of a neotropical palm

description: The idiosyncratic behaviors of seed dispersers are important contributors
 to plant spatial associations and genetic structures. In this study, we
 used a combination of field, molecular, and spatial studies to examine the
 connections between seed dispersal and the spatial and genetic structures
 of a dominant neotropical palm Attalea phalerata. Field observation and
 genetic parentage analysis both indicated that the majority of A.
 phalerata seeds were dispersed locally over short-distances (&lt; 30 m
 from the maternal tree). Spatial and genetic structures between adults and
 seedlings were consistent with localized and short-distance seed
 dispersal. Dispersal contributed to spatial associations among maternal
 sibling seedlings and strong spatial and genetic structures in both
 seedlings dispersed near (&lt;10 m) and away (&gt;10 m) from
 maternal palms. Seedlings were also spatially aggregated with juveniles.
 These patterns are likely associated with the dispersal of seeds by
 rodents and the survival of recruits at specific microsites or
 neighborhoods over successive fruiting periods. Our cross cohort analyses
 found palms in older cohorts and cohort-pairs were associated with a lower
 proportion of offspring and sibling neighbors and exhibited weaker spatial
 and genetic structures. Such patterns are consistent with increased
 distance- and density-dependent mortality over time among palms dispersed
 near maternal palms or siblings. The integrative approaches used for this
 study allowed us to infer the importance of seed dispersal activities in
 maintaining the aggregated distribution and significant genetic structures
 among A. phalerata palms. We further conclude that distance- and
 density-dependent mortality is a key post-dispersal process regulating
 this palm population.

title: Data from: Linking oceanographic conditions, migratory schedules and foraging behaviour during the non‐breeding season to reproductive performance in a long‐lived seabird

description: 1. Studies of the mechanisms underlying climate-induced population changes
 are critically needed to better understand and accurately predict
 population responses to climate change. Long-lived migratory species might
 be particularly vulnerable to climate change as they are constrained by
 different climate conditions and energetic requirements during the
 breeding and non-breeding seasons. Yet, most studies primarily focus on
 the breeding season of these species lifecycle. Environmental conditions
 experienced in the non-breeding season may have downstream effects on the
 other stages of the annual lifecycle. Not investigating such effects may
 potentially lead to erroneous inferences about population dynamics. 2.
 Combining demographic and tracking data collected between 2006 and 2013 at
 Kerguelen Island on a long-lived migratory seabird, the Black-Browed
 Albatross (Thalassarche melanophris), we investigated the links between
 sea surface temperature during the non-breeding season and behavioural and
 phenological traits (at-sea behaviour and migratory schedules) while
 accounting for different responses between birds of different sex and
 reproductive status (previously failed or successful breeders). We then
 explored if variation in the foraging behaviour and timing of spring
 migration influenced subsequent reproductive performance. 3. Our results
 showed that foraging activity and migratory schedules varied by both sex
 and reproductive status suggesting different energetic requirements and
 constraints among individuals. Higher sea surface temperatures during late
 winter, assumed to reflect poor winter conditions, were associated with an
 earlier departure from the wintering grounds and an extended pre-breeding
 period. However, an earlier spring migration and an earlier return to
 Kerguelen grounds were associated with a lower breeding success. 4. Our
 results highlighted that behaviour during some periods of the non-breeding
 season, particularly towards the end of the wintering period and the
 pre-breeding period had a significant effect on the subsequent
 reproductive success. Therefore, caution needs to be given to all stages
 of the annual cycle when predicting the influence of climate on population
 dynamics.

title: Data from: Cytoplasmic DNA variation and biogeography of Larix Mill. in Northeast Asia

description: Range-wide variation in 54 populations of Dahurian larch (Larix gmelinii)
 and related taxa in Northeast Asia was assessed with four mitochondrial
 PCR-RFLP and five chloroplast SSR markers. Eleven mitotypes and 115
 chlorotypes were detected. The highest diversity was observed in the
 southern Russian Far East where hybrids of L. gmelinii, L. olgensis and L.
 kamtschatica are distributed. In contrast, only two mitotypes occurred in
 L. cajanderi and L. gmelinii. The Japanese larch (L. kaempferi) was found
 to be closely related to populations of L. kamtschatika inhabiting the
 Kuril Islands and South Sakhalin, populations from the northern part of
 Sakhalin being more closely related to continental species. In general,
 both mitochondrial (GST = 0.786; NST = 0.823) and chloroplast (GST =
 0.144; RST = 0.432) markers showed a strong phylogeographical structure
 and evidence of isolation-by-distance. Yet both markers did not allow a
 clear delineation of species borders. In particular, and contrary to
 expectations, cpDNA was not significantly better than mtDNA to delineate
 species borders. This lack of concordance between morphological species
 and molecular markers could reflect extensive ancestral haplotype sharing
 and past and ongoing introgression. Finally the distribution of mtDNA and
 cpDNA variation suggests the presence of several refugia during
 Pleistocene glacial intervals. In particular, mDNA and cpDNA reveal weak
 but visible differentiation between L. gmelinii and L. cajanderi
 suggesting independent glacial histories of these species.

title: Data from: Faster development covaries with higher DNA damage in grasshoppers (Chorthippus albomarginatus) from Chernobyl

description: In Chernobyl, chronic exposure to radioactive contaminants has a variety
 of deleterious effects on exposed organisms, including genetic damage and
 mutation accumulation. The potential for such effects to be transmitted to
 the next generation is however poorly understood. We captured lesser marsh
 grasshoppers (Chorthippus albomarginatus) in the Chernobyl Exclusion Zone
 from sites varying in levels of environmental radiation by more than three
 orders of magnitude. We then raised their offspring in a common garden
 experiment in order to assess the effects of parental exposure to
 radiation on offspring development and DNA damage. Offspring that reached
 maturity at a younger age had higher levels of DNA damage. Contrary to our
 hypothesis, parental exposure to radioactive contamination did not affect
 DNA damage in their offspring, possibly due to intervening adaptation or
 to parental compensatory mechanisms. In addition, lower average DNA damage
 within a family was associated with higher survival in that family. Our
 results suggest a trade-off between developmental rate and resistance to
 DNA damage whereby offspring developing at faster rates do so at the cost
 of damaging their DNA. This result is consistent with and extends findings
 in other species suggesting that faster growth rates cause increased
 oxidative damage and stress. We propose that growth rates are subject to
 stabilizing selection balancing the benefits of fast development and the
 competing need of buffering its damaging effects to macromolecules and
 tissues.

title: Data from: Table scraps: inter-trophic food provisioning by pumas

description: Large carnivores perform keystone ecological functions through direct
 predation, or indirectly, through food subsidies to scavengers or trophic
 cascades driven by their influence on the distributions of their prey.
 Pumas (Puma concolor) are an elusive, cryptic species difficult to study,
 and little is known about their inter-trophic level interactions in
 natural communities. Using new GPS technology, we discovered that pumas in
 Patagonia provided 232 ± 31 kg of edible meat/month/100 km2 to
 near-threatened Andean condors (Vultur gryphus) and other members of a
 diverse scavenger community. This is up to 3.1 times the contributions by
 wolves (Canis lupus) to communities in Yellowstone National Park, USA, and
 highlights the keystone role large, solitary felids play in natural
 systems. These findings are more pertinent than ever, for managers
 increasingly advocate controlling pumas and other large felids to bolster
 prey populations and mitigate concerns over human and livestock safety,
 without a full understanding of the potential ecological consequences of
 their actions.

title: Data from: Diurnal lighting patterns and habitat alter opsin expression and colour preferences in a killifish

description: Spatial variation in lighting environments frequently leads to population
 variation in colour patterns, colour preferences and visual systems. Yet
 lighting conditions also vary diurnally, and many aspects of visual
 systems and behaviour vary over this time scale. Here, we use the bluefin
 killifish (Lucania goodei) to compare how diurnal variation and habitat
 variation (clear versus tannin-stained water) affect opsin expression and
 the preference to peck at different-coloured objects. Opsin expression was
 generally lowest at midnight and dawn, and highest at midday and dusk, and
 this diurnal variation was many times greater than variation between
 habitats. Pecking preference was affected by both diurnal and habitat
 variation but did not correlate with opsin expression. Rather, pecking
 preference matched lighting conditions, with higher preferences for blue
 at noon and for red at dawn/dusk, when these wavelengths are comparatively
 scarce. Similarly, blue pecking preference was higher in tannin-stained
 water where blue wavelengths are reduced. In conclusion, L. goodei
 exhibits strong diurnal cycles of opsin expression, but these are not
 tightly correlated with light intensity or colour. Temporally variable
 pecking preferences probably result from lighting environment rather than
 from opsin production. These results may have implications for the colour
 pattern diversity observed in these fish.

title: Data from: Morphometric investigation of the Pentremites fauna from the Glen Dean Formation, Kentucky

description: New techniques involving three-dimensional (3D) data collection and
 landmark analysis provide an opportunity to make breakthroughs in
 understanding blastoid morphology. This pilot study examines four species
 (Pentremites pyriformis, P. tulipiformis, P. fredericki n. sp., and P.
 meganae n. sp.), using 3D morphological variation and geometric
 morphometrics to discriminate between species. All specimens were
 collected from a single shale unit within the Upper Mississippian Glen
 Dean Formation near Hopkinsville, Kentucky. A 3D laser scanner was used to
 acquire 3D images for all specimens. Conservative blastoid thecal plating
 allowed the collection of 3D coordinates for a series of homologous
 landmarks from these laser images that fully describe specimen morphology.
 Data were analyzed using the R (language and environment for statistical
 computing and graphics) packages SHAPES and MCLUST. Mixture modeling
 identified and separated all four species based on shape alone. In
 addition, three new species were uncovered during this study, including:
 Pentremites fredericki, P. meganae and Diploblastus fadigai.

title: Data from: Evolutionary associations between host traits and parasite load: insights from Lake Tanganyika cichlids

description: Parasite diversity and abundance (parasite load) vary greatly among host
 species. However, the influence of host traits on variation in parasitism
 remains poorly understood. Comparative studies of parasite load have
 largely examined measures of parasite species richness and are
 predominantly based on records obtained from published data. Consequently,
 little is known about the relationships between host traits and other
 aspects of parasite load, such as parasite abundance, prevalence and
 aggregation. Meanwhile, understanding of parasite species richness may be
 clouded by limitations associated with data collation from multiple
 independent sources. We conducted a field study of Lake Tanganyika cichlid
 fishes and their helminth parasites. Using a Bayesian phylogenetic
 comparative framework, we tested evolutionary associations between five
 key host traits (body size, gut length, diet breadth, habitat complexity
 and number of sympatric hosts) predicted to influence parasitism, together
 with multiple measures of parasite load. We find that the number of host
 species that a particular host may encounter due to its habitat
 preferences emerges as a factor of general importance for parasite
 diversity, abundance and prevalence, but not parasite aggregation. In
 contrast, body size and gut size are positively related to aspects of
 parasite load within, but not between species. The influence of host
 phylogeny varies considerably among measures of parasite load, with the
 greatest influence exerted on parasite diversity. These results reveal
 that both host morphology and biotic interactions are key determinants of
 host–parasite associations and that consideration of multiple aspects of
 parasite load is required to fully understand patterns in parasitism.
