title: Data from: Spatial and temporal variation in grazing damage by the gastropod Lacuna vincta in Nova Scotian kelp beds

description: Population increases of the gastropod Lacuna vincta have been associated
 with significant damage to kelp blades and decreases in kelp biomass in
 subtidal kelp beds off Nova Scotia, Canada. We measured the total level
 and along-blade distribution of grazing damage by Lacuna vincta on the
 dominant kelp species at 5 sites in Nova Scotia, Canada, over a 15 mo
 period. Grazing was typically low or absent in the basal regions of
 blades, consistent with seasonal fluctuations in growth and physical
 properties of blade tissues. Grazing was largely concentrated in middle
 and distal sections, although this distribution varied with site exposure
 and over time. The cover of the invasive bryozoan Membranipora membranacea
 on the surface of kelp blades did not have a strong effect on grazing by
 L. vincta. The total level of grazing damage (max. 1% of blade area for
 Saccharina longicruris and 1.5% for Laminaria digitata) varied seasonally,
 with peaks in September at some sites. Spatial variation was driven in
 part by a negative relationship with site exposure. In a field experiment,
 simulated grazing damage that exceeded a threshold value of 0.5 to 1.0% of
 blade area caused a significant increase in blade loss during a period of
 heavy wave action due to a passing hurricane. Our results show that direct
 reductions in kelp biomass through grazing by L. vincta are relatively
 small, but can indirectly lead to significant losses of kelp biomass
 during large wave events.

title: Data from: Naturally occurring variation in tadpole morphology and performance linked to predator regime

description: Divergent natural selection drives a considerable amount of the phenotypic
 and genetic variation observed in natural populations. For example,
 variation in the predator community can generate conflicting selection on
 behavioral, life-history, morphological, and performance traits.
 Differences in predator regime can subsequently increase phenotypic and
 genetic variations in the population and result in the evolution of
 reproductive barriers (ecological speciation) or phenotypic plasticity. We
 evaluated morphology and swimming performance in field collected Bronze
 Frog larvae (Lithobates clamitans) in ponds dominated by predatory fish
 and those dominated by invertebrate predators. Based on previous
 experimental findings, we hypothesized that tadpoles from fish-dominated
 ponds would have small bodies, long tails, and large tail muscles and that
 these features would facilitate fast-start speed. We also expected to see
 increased tail fin depth (i.e., the tail-lure morphology) in tadpoles from
 invertebrate-dominated ponds. Our results support our expectations with
 respect to morphology in affecting swimming performance of tadpoles in
 fish-dominated ponds. Furthermore, it is likely that divergent natural
 selection is playing a role in the diversification on morphology and
 locomotor performance in this system.

title: Data from: Dispersal propensity in Tetrahymena thermophila ciliates – a reaction norm perspective

description: Dispersal and phenotypic plasticity are two main ways for species to deal
 with rapid changes of their environments. Understanding how genotypes (G),
 environments (E) and their interaction (genotype and environment; G x E)
 each affects dispersal propensity is therefore instrumental for predicting
 the ecological and evolutionary responses of species under global change.
 Here we used an actively dispersing ciliate to quantify the contributions
 of G, E, and G x E on dispersal propensity, exposing 44 different
 genotypes to three different environmental contexts (densities in
 isogenotype populations). Moreover, we assessed the condition-dependence
 of dispersal, i.e. whether dispersal is related to morphological,
 physiological or behavioral traits. We found that genotypes showed marked
 differences in dispersal propensity and that dispersal is plastically
 adjusted to density, with the overall trend for genotypes to exhibit
 negative density-dependent dispersal. A small, but significant G x E
 interaction indicates genetic variability in plasticity and therefore some
 potential for dispersal plasticity to evolve. We also show evidence
 consistent with condition-dependent dispersal suggesting that genotypes
 also vary in how individual condition is linked to dispersal under
 different environmental contexts thereby generating complex dispersal
 behavior due to only three variables (genes, environment, and individual
 condition).

title: Data from: Geohistorical records indicate no impact of the Deepwater Horizon oil spill on oyster body size

description: Documentation of the near- and long-term effects of the Deepwater Horizon
 (DWH) oil spill, one of the largest environmental disasters in US history,
 is still ongoing. We used a novel before-after-control-impact analysis to
 test the hypothesis that average body size of intertidal populations of
 the eastern oyster (Crassostrea virginica) inhabiting impacted areas in
 Louisiana decreased due to increased stress/mortality related to the oil
 spill. Time-averaged death assemblages of oysters were used to establish a
 pre-spill baseline of body-size structure for four impacted and four
 control locations along a 350 km stretch of Louisiana's coastline.
 Post-spill body sizes were then measured from live oysters at each site in
 order to evaluate the differences in body size between oiled (i.e. impact)
 and unoiled (i.e. control) locations before and after the spill. Our
 results indicate that average body size of oysters remained relatively
 unchanged after the oil spill. There were also no temporal patterns in
 temperature, salinity or disease prevalence that could have explained our
 results. Together, these findings suggest that oysters either recovered
 rapidly following the immediate impact of the DWH oil spill, or that its
 impact was not severe enough to influence short-term population dynamics
 of the oyster beds.

title: Data from: Evidence of phenotypic plasticity of penis morphology and delayed reproductive maturation in response to male competition in waterfowl

description: Ducks are an excellent group to study avian genital evolution. Penis
 morphology of ducks is diverse, and penis length and elaboration are
 positively correlated with levels of male competition resulting from
 forced extra-pair copulations, and with female genital elaboration
 resulting from sexual conflict. Here we examined whether penis morphology
 is affected by social environment. We found experimental evidence that in
 a male-biased social environment, consisting of several males and fewer
 females, the penis in Lesser Scaup (Aythya affinis) grew longer in 2
 separate years, than in males housed in pairs, as predicted if male–male
 competition influences penis morphology. In Ruddy Ducks (Oxyura
 jamaicensis), males instead showed evidence of reproductive delays that
 were explained both by a male's size and his social environment: most
 males in social groups exhibited shorter penises, variable onset and
 duration of genital maturation, and faster penis growth rate. These 2
 species have different levels of post-copulatory competition in nature,
 with Ruddy Ducks having more extreme penis sizes and more promiscuity than
 Lesser Scaup. The results suggest that waterfowl can exhibit complex,
 socially dependent phenotypic plasticity and reproductive maturation that
 can generate intraspecific variation in their genitalia.

title: Data from: Surrogate taxa and fossils as reliable proxies of spatial biodiversity patterns in marine benthic communities

description: Rigorous documentation of spatial heterogeneity (β-diversity) in
 present-day and preindustrial ecosystems is required to assess how marine
 communities respond to environmental and anthropogenic drivers. However,
 the overwhelming majority of contemporary and palaeontological assessments
 have centred on single higher taxa. To evaluate the validity of single
 taxa as community surrogates and palaeontological proxies, we compared
 macrobenthic communities and sympatric death assemblages at 52 localities
 in Onslow Bay (NC, USA). Compositional heterogeneity did not differ
 significantly across datasets based on live molluscs, live non-molluscs,
 and all live organisms. Death assemblages were less heterogeneous
 spatially, likely reflecting homogenization by time-averaging.
 Nevertheless, live and dead datasets were greater than 80% congruent in
 pairwise comparisons to the literature estimates of β-diversity in other
 marine ecosystems, yielded concordant bathymetric gradients, and produced
 nearly identical ordinations consistently delineating habitats. Congruent
 estimates from molluscs and non-molluscs suggest that single groups can
 serve as reliable community proxies. High spatial fidelity of death
 assemblages supports the emerging paradigm of Conservation Palaeobiology.
 Integrated analyses of ecological and palaeontological data based on
 surrogate taxa can quantify anthropogenic changes in marine ecosystems and
 advance our understanding of spatial and temporal aspects of biodiversity.

title: Data from: An ancient origin for the enigmatic Flat-Headed Frogs (Bombinatoridae: Barbourula) from the islands of Southeast Asia

description: Background: The complex history of Southeast Asian islands has long been
 of interest to biogeographers. Dispersal and vicariance events in the
 Pleistocene have received the most attention, though recent studies
 suggest a potentially more ancient history to components of the
 terrestrial fauna. Among this fauna is the enigmatic archaeobatrachian
 frog genus Barbourula, which only occurs on the islands of Borneo and
 Palawan. We utilize this lineage to gain unique insight into the temporal
 history of lineage diversification in Southeast Asian islands.
 Methodology/Principal Findings: Using mitochondrial and nuclear genetic
 data, multiple fossil calibration points, and likelihood and Bayesian
 methods, we estimate phylogenetic relationships and divergence times for
 Barbourula. We determine the sensitivity of focal divergence times to
 specific calibration points by jackknife approach in which each
 calibration point is excluded from analysis. We find that relevant
 divergence time estimates are robust to the exclusion of specific
 calibration points. Barbourula is recovered as a monophyletic lineage
 nested within a monophyletic Costata. Barbourula diverged from its sister
 taxon Bombina in the Paleogene and the two species of Barbourula diverged
 in the Late Miocene. Conclusions/Significance: The divergences within
 Barbourula and between it and Bombina are surprisingly old and represent
 the oldest estimates for a cladogenetic event resulting in living taxa
 endemic to Southeast Asian islands. Moreover, these divergence time
 estimates are consistent with a new biogeographic scenario: the Palawan
 Ark Hypothesis. We suggest that components of Palawan’s terrestrial fauna
 might have ‘‘rafted’’ on emergent portions of the North Palawan Block
 during its migration from the Asian mainland to its present-day position
 near Borneo. Further, dispersal from Palawan to Borneo (rather than Borneo
 to Palawan) may explain the current day disjunct distribution of this
 ancient lineage.

title: Data from: Symbiotic polydnavirus of a parasite manipulates caterpillar and plant immunity

description: Obligate symbioses occur when organisms require symbiotic relationships to
 survive. Some parasitic wasps of caterpillars possess obligate mutualistic
 viruses called “polydnaviruses.” Along with eggs, wasps inject
 polydnavirus inside their caterpillar hosts where the hatching larvae
 develop inside the caterpillar. Polydnaviruses suppress the immune systems
 of their caterpillar hosts, which enables egg hatch and wasp larval
 development. It is unknown whether polydnaviruses also manipulate the
 salivary proteins of the caterpillar, which may affect the elicitation of
 plant defenses during feeding by the caterpillar. Here, we show that a
 polydnavirus of the parasitoid Microplitis croceipes, and not the
 parasitoid larva itself, drives the regulation of salivary enzymes of the
 caterpillar Helicoverpa zea that are known to elicit tomato plant-defense
 responses to herbivores. The polydnavirus suppresses glucose oxidase,
 which is a primary plant-defense elicitor in the saliva of the H. zea
 caterpillar. By suppressing plant defenses, the polydnavirus allows the
 caterpillar to grow at a faster rate, thus improving the host suitability
 for the parasitoid. Remarkably, polydnaviruses manipulate the phenotypes
 of the wasp, caterpillar, and host plant, demonstrating that
 polydnaviruses play far more prominent roles in shaping plant–herbivore
 interactions than ever considered.

title: Data from: Offspring dynamics affect food provisioning, growth and mortality in a brood-caring spider

description: In brood-caring species, family members are faced with a conflict over
 resource distribution. While parents are selected to adapt the amount of
 care according to their offspring's needs, offspring might be
 selected to demand more care than optimal for parents. Recent studies on
 birds have shown that the social network structure of offspring affects
 the amount of care and thus the fitness of families. Such a network
 structure of repeated interactions is probably influenced by within-brood
 relatedness. We experimentally manipulated the group composition in a
 brood-caring spider to test how the presence of unrelated spiderlings
 affects the dynamics between female and brood as well as within broods.
 Broods consisting of siblings grew better and had a lower mortality
 compared with mixed broods, no matter whether the caring female was a
 genetic or foster mother. Interestingly, we found that foster mothers lost
 weight when caring for sibling broods, whereas females caring for mixed
 broods gained weight. This indicates that females may be willing to share
 more prey when the brood contains exclusively siblings even if the entire
 brood is unrelated to the female. Resource distribution may thus be
 negotiated by offspring dynamics that could have a signalling function to
 females.

title: Data from: Genetic differentiation and phylogeographical structure of the Brachionus calyciflorus complex in eastern China

description: Spatio-temporal patterns and processes of genetic differentiation in
 passively dispersing zooplankton are drawing much attention from both
 ecologists and evolutionary biologists. Two opposite phylogeographical
 scenarios have already been demonstrated in rotifers, which consist of
 high levels of genetic differentiation among populations even on small
 geographical scales on the one hand, and the traditionally known
 cosmopolitanism that is associated with high levels of gene flow and
 long-distance dispersal via diapausing stages on the other hand. Here we
 analyzed the population genetic structure and the phylogeography of the
 Brachionus calyciflorus species complex in eastern China. By screening a
 total of 318 individuals from ten locations along a 2320 km gradient and
 analyzing samples from two growing seasons, we aimed at focusing on both
 small- and large-scale patterns. We identified eight cryptic species, and
 verified species status of two of these by sexual reproduction tests.
 Samples in summer and winter yielded different cryptic species. The
 distribution patterns of these genetically distinct cryptic species were
 diverse across eastern China, from full cosmopolitanism to local endemism.
 The two most abundant cryptic species BcWIII and BcSW both showed a
 pattern of strong genetic differentiation among populations and no
 significant isolation-by-distance. Long-distance colonization, secondary
 contact and recent range expansion are probably responsible for the
 indistinct pattern of isolation-by-distance. Our results suggest that
 geographical distance is more important than temporal segregation across
 seasons in explaining population differentiation and the occurrence of
 cryptic species. We explain the current phylogeographical structure in the
 B. calyciflorus species complex by a combination of recent population
 expansion, restricted gene flow, priority effects and long-distance
 colonization.
