title: Data from: Cell proliferation and migration during early development of a symbiotic scleractinian coral

description: In scleractinian reef-building corals, patterns of cell self-renewal,
 migration and death remain virtually unknown, limiting our understanding
 of cellular mechanisms underlying initiation of calcification, and
 ontogenesis of the endosymbiotic dinoflagellate relationship. In this
 study we pulse-labeled the coral Stylophora pistillata for 24 h with BrdU
 at four life stages (planula, early metamorphosis, primary polyp, and
 adult colony) to investigate coral and endosymbiont cell proliferation
 during development, while simultaneously recording TUNEL-positive, i.e.
 apoptotic, nuclei. In the primary polyp, the fate of BrdU-labeled cells
 was tracked during a 3 days chase. The pharynx and gastrodermis were
 identified as the most proliferative tissues in the developing polyp, and
 BrdU-labeled cells accumulated in the surface pseudostratified epithelium
 and the skeletogenic calicodermis during the chase, revealing cell
 migration to these epithelia. Surprisingly, the lowest cell turnover was
 recorded in the calicodermis at all stages, despite active, ongoing
 skeletal deposition. In dinoflagellate symbionts, DNA synthesis was
 systematically higher than in coral host gastrodermis, especially in
 planula and early metamorphosis. The symbiont to host cell ratio remained
 however constant, indicating successive post-mitotic control mechanisms by
 the host of its dinoflagellate density in early life stages, increasingly
 shifting to apoptosis in the growing primary polyp.

title: Data from: The effects of milkweed induced defense on parasite resistance in monarch butterflies, Danaus plexippus

description: Many plants express induced defenses against herbivores through increasing
 the production of toxic secondary chemicals following damage.
 Phytochemical induction can directly or indirectly affect other organisms
 within the community. In tri-trophic systems, increased concentrations of
 plant toxins could be detrimental to plants if herbivores can sequester
 these toxins as protective chemicals for themselves. Thus, through trophic
 interactions, induction can lead to either positive or negative effects on
 plant fitness. We examined the effects of milkweed (Asclepias spp.)
 induced defenses on the resistance of monarch caterpillars (Danaus
 plexippus) to a protozoan parasite (Ophryocystis elektroscirrha).
 Milkweeds contain toxic secondary chemicals called cardenolides, higher
 concentrations of which are associated with reduced parasite growth.
 Previous work showed that declines in foliar cardenolides caused by aphid
 attack render monarch caterpillars more susceptible to infection. Here, we
 ask whether cardenolide induction by monarchs increases monarch resistance
 to disease. We subjected the high-cardenolide milkweed A. curassavica and
 the low-cardenolide A. syriaca to caterpillar grazing, and reared infected
 and uninfected caterpillars on these plants. As expected, monarchs
 suffered less parasite growth and disease when reared on A. curassavica
 than on A. syriaca. We also found that herbivory increased cardenolide
 concentrations in A. curassavica, but not A. syriaca. However, cardenolide
 induction in A. curassavica was not strong enough to influence monarch
 resistance to the parasite. Our results suggest that interspecific
 variation in cardenolide concentration is a more important driver of
 parasite defense than plasticity via induced defenses in this tri-trophic
 system.

title: Data from: Energy storage and fecundity explain deviations from ecological stoichiometry predictions under global warming and size-selective predation

description: A key challenge for ecologists is to predict how single and joint effects
 of global warming and predation risk translate from the individual level
 up to ecosystem functions. Recently, stoichiometric theory linked these
 levels through changes in body stoichiometry, predicting that both higher
 temperatures and predation risk induce shifts in energy storage (increases
 in C-rich carbohydrates and reductions in N-rich proteins) and body
 stoichiometry (increases in C : N and C : P). This promising theory,
 however, is rarely tested and assumes that prey will divert energy away
 from reproduction under predation risk, while under size-selective
 predation, prey instead increase fecundity. We exposed the water flea
 Daphnia magna to 4 °C warming and fish predation risk to test whether
 C-rich carbohydrates increase and N-rich proteins decrease, and as a
 result, C : N and C : P increase under warming and predation risk.
 Unexpectedly, warming decreased body C : N, which was driven by reductions
 in C-rich fat and sugar contents while the protein content did not change.
 This reflected a trade-off where the accelerated intrinsic growth rate
 under warming occurred at the cost of a reduced energy storage. Warming
 reduced C : N less and only increased C : P and N : P in the fish-period
 Daphnia. These evolved stoichiometric responses to warming were largely
 driven by stronger warming-induced reductions in P than in C and N and
 could be explained by the better ability to deal with warming in the
 fish-period Daphnia. In contrast to theory predictions, body C : N
 decreased under predation risk due to a strong increase in the N-rich
 protein content that offsets the increase in C-rich fat content. The
 higher investment in fecundity (more N-rich eggs) under predation risk
 contributed to this stronger increase in protein content. Similarly, the
 lower body C : N of pre-fish Daphnia also matched their higher fecundity.
 Warming and predation risk independently shaped body stoichiometry,
 largely by changing levels of energy storage molecules. Our results
 highlight that two widespread patterns, the trade-off between rapid
 development and energy storage and the increased investment in
 reproduction under size-selective predation, cause predictable deviations
 from current ecological stoichiometry theory.

title: Data from: Forecasting potential routes for movement of endemic birds among important sites for biodiversity in the Albertine Rift under projected climate change

description: The ability of species to shift their distributions in response to climate
 change may be impeded by lack of suitable climate or habitat between
 species’ current and future ranges. We examined the potential for climate
 and forest cover to limit the movement of bird species among sites of
 biodiversity importance in the Albertine Rift, East Africa, a biodiversity
 hotspot. We forecasted future distributions of suitable climate for 12
 Albertine Rift endemic bird species using species distribution models
 based on current climate data and projections of future climate. We used
 these forecasts alongside contemporary forest cover and natal dispersal
 estimates to project potential movement of species over time. We
 identified potentially important pathways for the bird species to move
 among 30 Important Bird and Biodiversity Areas (IBAs) that are both
 currently forested and projected to provide suitable climate over
 intervening time periods. We examined the relative constraints imposed by
 availability of suitable climate and forest cover on future movements. The
 analyses highlighted important pathways of potential dispersal lying along
 a north-south axis through high elevation areas of the Albertine Rift.
 Both forest availability and climate suitability were projected to
 influence bird movement through these landscapes as they are affected by
 future climate change. Importantly, forest cover and areas projected to
 contain suitable climate in future were often dissociated in space, which
 could limit species’ responses to climate change. A lack of climatically
 suitable areas was a far greater impediment to projected movement among
 IBAs than insufficient forest cover. Although current forest cover appears
 sufficient to facilitate movement of bird species in this region,
 protecting the remaining forests in areas also projected to be
 climatically suitable for species to move through in the future should be
 a priority for adaptation management.

title: Data from: The phylogenetic basis of sexual size dimorphism in orb-weaving spiders (Araneae, Orbiculariae)

description: Extreme sexual body size dimorphism (SSD), in which males are only a small
 fraction of the size of the females, occurs only in a few, mostly marine,
 taxonomic groups. Spiders are the only terrestrial group in which small
 males are relatively common, particularly among orb-weavers (especially in
 the families Tetragnathidae and Araneidae) and crab spiders (Thomisidae).
 We use a taxonomic sample of 80 genera to study the phylogenetic patterns
 (origins and reversals) of SSD in orb-weaving spiders (Orbiculariae). We
 collected and compiled male and female size data (adult body length) for
 536 species. Size data were treated as a continuous character and
 ancestral sizes, for males and females separately, were reconstructed
 using Wagner parsimony on a cladogram for the 80 genera used in this
 study. Of the 80 genera in the analysis, 24 were female-biased dimorphic
 (twice or more the body length of the male); the remaining 56 genera were
 monomorphic. Under parsimony only four independent origins of dimorphism
 are required: in the theridiid genus Tidarren, in the distal nephilines,
 in the "argiopoid clade," and in the araneid genus Kaira.
 Dimorphism has reversed to monomorphism at least seven times, all of them
 within the large "argiopoid clade." The four independent origins
 of dimorphism represent two separate instances of an increase in female
 size coupled with a decrease of male size (involving only two genera), and
 two separate instances of an increase in female size with male size either
 remaining the same or increasing, but not as much as females (involving 30
 genera). In orb-weaving spiders far more taxa are sexually dimorphic as a
 result of female size increase (22 genera) than as a result of male size
 decrease (two genera). SSD in orb-weaving spiders encompasses several
 independent evolutionary histories that together suggest a variety of
 evolutionary pathways. This multiplicity strongly refutes all efforts to
 date to find a general explanation for either the origin or maintenance
 (or both) of SSD, because the different pathways very likely will require
 distinctly different, possibly unique, explanations. Each pattern must be
 understood historically before its origin and maintenance can be explained
 in ecological and evolutionary terms. The most frequently cited example of
 male dwarfism in spiders, the golden orb spider genus Nephila
 (Tetragnathidae), is in fact a case of female giantism, not male dwarfism.

title: Data from: Mixed population genomics support for the central marginal hypothesis across the invasive range of the cane toad (Rhinella marina) in Australia

description: Understanding factors that cause species' geographic range limits is
 a major focus in ecology and evolution. The central marginal hypothesis
 (CMH) predicts that species cannot adapt to conditions beyond current
 geographic range edges because genetic diversity decreases from core to
 edge due to smaller, more isolated edge populations. We employed a
 population genomics framework using 24 235–33 112 SNP loci to test major
 predictions of the CMH in the ongoing invasion of the cane toad (Rhinella
 marina) in Australia. Cane toad tissue samples were collected along
 broad-scale, core-to-edge transects across their invasive range.
 Geographic and ecological core areas were identified using GIS and habitat
 suitability indices from ecological niche modelling. Bayesian clustering
 analyses revealed three genetic clusters, in the northwest invasion-front
 region, northeast precipitation-limited region and southeast cold
 temperature-limited region. Core-to-edge patterns of genetic diversity and
 differentiation were consistent with the CMH in the southeast, but were
 not supported in the northeast and showed mixed support in the northwest.
 Results suggest cold temperatures are a likely contributor to southeastern
 range limits, consistent with CMH predictions. In the northeast and
 northwest, ecological processes consisting of a steep physiological
 barrier and ongoing invasion dynamics, respectively, are more likely
 explanations for population genomic patterns than the CMH.

title: Data from: Experimental evolution of infectious behaviour in a facultative ectoparasite

description: Parasitic lifestyles have evolved many times in animals, but how such
 life-history strategies evolved from free-living ancestors remains a great
 puzzle. Transitional symbiotic strategies, such as facultative parasitism,
 are hypothesized evolutionary stepping-stones towards obligate parasitism.
 However, to consider this hypothesis, heritable genetic variation in
 infectious behaviour of transitional symbiotic strategies must exist. In
 this study, we experimentally evolved infectivity and estimated the
 additive genetic variation in a facultative parasite. We performed
 artificial selection experiments in which we selected for either increased
 or decreased propensity to infect in a facultatively parasitic mite
 (Macrocheles muscaedomesticae). Here, infectiousness was expressed in
 terms of mite attachment to a host (Drosophila hydei) and modeled as a
 threshold trait. Mites responded positively to selection for increased
 infectivity; realized heritability of infectious behaviour was
 significantly different from zero and estimated to be 16.6% (±4.4% SE).
 Further, infection prevalence was monitored for 20 generations
 post-selection. Selected lines continued to display relatively high levels
 of infection demonstrating a degree of genetic stability in
 infectiousness. Our study is the first to provide an estimate of
 heritability and additive genetic variation for infectious behaviour in a
 facultative parasite, which suggests natural selection can act upon
 facultative strategies with important implications for the evolution of
 parasitism.

title: Data from: Fluid-dynamic optimal design of helical vascular graft for stenotic disturbed flow

description: Although a helical configuration of a prosthetic vascular graft appears to
 be clinically beneficial in suppressing thrombosis and intimal
 hyperplasia, an optimization of a helical design has yet to be achieved
 because of the lack of a detailed understanding on hemodynamic features in
 helical grafts and their fluid dynamic influences. In the present study,
 the swirling flow in a helical graft was hypothesized to have beneficial
 influences on a disturbed flow structure such as stenotic flow. The
 characteristics of swirling flows generated by helical tubes with various
 helical pitches and curvatures were investigated to prove the hypothesis.
 The fluid dynamic influences of these helical tubes on stenotic flow were
 quantitatively analysed by using a particle image velocimetry technique.
 Results showed that the swirling intensity and helicity of the swirling
 flow have a linear relation with a modified Germano number (Gn*) of the
 helical pipe. In addition, the swirling flow generated a beneficial flow
 structure at the stenosis by reducing the size of the recirculation flow
 under steady and pulsatile flow conditions. Therefore, the beneficial
 effects of a helical graft on the flow field can be estimated by using the
 magnitude of Gn*. Finally, an optimized helical design with a maximum Gn*
 was suggested for the future design of a vascular graft.

title: Data from: Spatially variable habitat quality contributes to within-population variation in reproductive success

description: Variation in habitat quality is common across terrestrial, freshwater, and
 marine habitats. We investigated how habitat quality influenced the
 reproductive potential of mud crabs across 30 oyster reefs that were
 degraded to different extents. We further coupled this field survey with a
 laboratory experiment designed to mechanistically determine the
 relationship between resource consumption and reproductive performance. We
 show a &gt;10-fold difference in average reproductive potential for
 crabs across reefs of different quality. Calculated consumption rates for
 crabs in each reef, based on a type II functional response, suggest that
 differences in reproductive performance may be attributed to resource
 limitation in poor quality reefs. This conclusion is supported by results
 of our laboratory experiment where crabs fed a higher quality diet of
 abundant animal tissue had greater reproductive performance. Our results
 demonstrate that spatial variation in habitat quality can be a
 considerable contributor to within-population individual variation in
 reproductive success (i.e., demographic heterogeneity). This finding has
 important implications for assessing population extinction risk.

title: Data from: Hypoxia increases the risk of egg predation in a nest-guarding fish

description: For fish with parental care, a nest should meet both the oxygenation needs
 of the eggs and help protect them against predators. While a small nest
 opening facilitates the latter, it impedes the former and vice versa. We
 investigated how the presence of potential egg predators in the form of
 shore crabs Carcinus maenas affects nest building, egg fanning, defensive
 displays and filial cannibalism of egg-guarding male sand gobies
 Pomatoschistus minutus under two levels of dissolved oxygen. In the high
 oxygen treatment, males retained their nest opening size in the presence
 of crabs, while males in low oxygen built large nest openings both in the
 absence and presence of crabs, despite the fact that crabs were more
 likely to successfully intrude into nests with large entrances. Males in
 low oxygen also fanned more. In the presence of crabs males increased
 their defensive displays, but while males in high oxygen reduced fanning,
 males in low oxygen did not. Filial cannibalism was unaffected by
 treatment. Sand gobies thus prioritize egg ventilation over the protection
 afforded by small nest openings under hypoxia and adopt defensive
 behaviour to avert predator attention, even though this does not fully
 offset the threat from the egg predators.
