title: Data from: Caste ratios affect the reproductive output of social trematode colonies

description: Intraspecific phenotypic diversification in social organisms often leads
 to formation of physical castes which are morphologically specialised for
 particular tasks within the colony. The optimal caste allocation theory
 argues that specialised morphological castes are efficient at specific
 tasks, and hence different caste ratios should affect the ergonomic
 efficiency, hence reproductive output of the colony. However, the
 reproductive output of different caste ratios has been documented only in
 few species of insects with equivocal support for the theory. The present
 study investigated whether the ratios of non-reproductive and reproductive
 morphs affect the reproductive output of a recently discovered social
 trematode, Philophthalmus sp., in which the non-reproductive members are
 hypothesized to be defensive specialists. Census of natural infections and
 a manipulative in-vitro experiment demonstrated a positive association
 between the reproductive output of trematode colonies and the ratio of
 non-reproductive to reproductive morphs in the presence of an intra-host
 trematode competitor, Maritrema novaezealandensis. On the contrary,
 without the competitor, reproductive output was negatively associated with
 the proportion of non-reproductive castes in colonies. Our findings
 demonstrate for the first time a clear fitness benefit associated with the
 non-reproductive castes in the presence of a competitor while illustrating
 the cost of maintaining such morphs in non-competitive situations.
 Although the proximate mechanisms controlling caste ratio remain unclear
 in this trematode system, the present study supports the prediction that
 the fitness of colonies is influenced by the composition of specialized
 functional morphs in social organisms, suggesting a potential for adaptive
 shifts of caste ratios over evolutionary time.

title: Data from: Social information from immigrants: multiple immigrant based sources of information for dispersal decisions in a ciliate

description: 1. Dispersal is increasingly recognized as being an informed process,
 based on information organisms obtain about the landscape. While local
 conditions are often found to drive dispersal decisions, local context is
 not always a reliable predictor of conditions in neighbouring patches,
 making the use of local information potentially useless or even
 maladaptive. In this case, using social information gathered by immigrants
 might allow adjusting dispersal decisions without paying the costs of
 prospecting. However, this hypothesis has been largely neglected despite
 its major importance for ecological and evolutionary processes. 2. We
 investigated three fundamental questions about immigrant-informed
 dispersal: Do immigrants convey information that influences dispersal, do
 organisms use multiple cues from immigrants, and is immigrant-informed
 dispersal genotype dependent? 3. Using Tetrahymena thermophila ciliates in
 microcosms, we manipulated the number of immigrants arriving, the density
 of congeners, the resource quality in neighbouring patches, matrix
 characteristics and the level of cooperation of individuals in the
 neighbouring populations. 4. We provide the first experimental evidence
 that immigrants convey a number of different cues about neighbouring
 patches and matrix (patch quality, matrix characteristics and cooperation
 in neighbouring populations) in this relatively simple organism.
 Furthermore, we demonstrate genotype-dependent immigrant-informed
 dispersal decisions about patch quality and matrix characteristics. 5.
 Multiple cues from immigrants and genotype-dependent use of cues have
 major implications for theoretical metapopulation dynamics and the
 potential for local adaptation.

title: Data from: Evolution of organismal stoichiometry in a long-term experiment with Escherichia coli

description: Organismal stoichiometry refers to the relative proportion of chemical
 elements in the biomass of organisms, and it can have important effects on
 ecological interactions from population to ecosystem scales. Although
 stoichiometry has been studied extensively from an ecological perspective,
 much less is known about the rates and directions of evolutionary changes
 in elemental composition. We measured carbon, nitrogen and phosphorus
 content of 12 Escherichia coli populations that evolved under controlled
 carbon-limited, serial-transfer conditions for 50 000 generations. The
 bacteria evolved higher relative nitrogen and phosphorus content,
 consistent with selection for increased use of the more abundant elements.
 Total carbon assimilated also increased, indicating more efficient use of
 the limiting element. We also measured stoichiometry in one population
 repeatedly through time. Stoichiometry changed more rapidly in early
 generations than later on, similar to the trajectory seen for competitive
 fitness. Altogether, our study shows that stoichiometry evolved over long
 time periods, and that it did so in a predictable direction, given the
 carbon-limited environment.

title: Data from: Bottom-up and trait-mediated effects of resource quality on amphibian parasitism

description: Leaf litter subsidies are important resources for aquatic consumers like
 tadpoles and snails, causing bottom-up effects on wetland ecosystems.
 Recent studies have shown that variation in litter nutritional quality can
 be as important as litter quantity in driving these bottom-up effects.
 Resource subsidies likely also have indirect and trait-mediated effects on
 predation and parasitism, but these potential effects remain largely
 unexplored. We generated predictions for differential effects of litter
 nutrition and secondary polyphenolic compounds on tadpole (Lithobates
 sylvatica) exposure and susceptibility to Ribeiroia ondatrae, based on
 ecological stoichiometry and community-ecology theory. We predicted direct
 and indirect effects on key traits of the tadpole host (rates of growth,
 development and survival), the trematode parasite (production of the
 cercaria infective stages) and the parasite's snail intermediate host
 (growth and reproduction). To test these predictions, we conducted a
 large-scale mesocosm experiment using a natural gradient in the
 concentrations of nutrients (nitrogen) and toxic secondary compounds
 (polyphenolics) of nine leaf litter species. To differentiate between
 effects on exposure vs. susceptibility to infection, we included multiple
 infection experiments including one with constant per capita exposure. We
 found that increased litter nitrogen increased tadpole survival, and also
 increased cercaria production by the snail intermediate hosts, causing
 opposing effects on tadpole per capita exposure to trematode infection.
 Increased litter polyphenolics slowed tadpole development, leading to
 increased infection by increasing both their susceptibility to infection
 and the length of time they were exposed to parasites. Based on these
 results, recent shifts in forest composition towards more nitrogen-poor
 litter species should decrease trematode infection in tadpoles via
 density- and trait-mediated effects on the snail intermediate hosts.
 However, these shifts also involve increased abundance of litter species
 with high polyphenolic levels, which should increase trematode infection
 via trait-mediated effects on tadpoles. Future studies will be needed to
 determine the relative strength of these opposing effects in natural
 wetland communities.

title: Data from: Local adaptation of fish consumers alters primary production through changes in algal community composition and diversity

description: Ecological research has focused on understanding how changes in consumer
 abundance affect community structure and ecosystem processes. However,
 there is increasing evidence that evolutionary changes in consumers can
 also alter community structure and ecosystem processes. Typically, the
 effects of consumer phenotype on communities and ecosystem processes are
 measured as net effects that integrate numerous ecological pathways. Here,
 we analyze new data from experimental manipulations of Trinidadian guppy
 Poecilia reticulata presence, density and phenotype to examine how effects
 on the algal community cause changes in gross-primary production (GPP). We
 combine analytical tools borrowed from path analysis with experimental
 exclosures in mesocosms to separate the ecological and evolutionary
 effects of guppies into direct and indirect components. We show that the
 evolutionary effects of guppy phenotype act through different ecological
 pathways than the effects of guppy presence and density on GPP. As
 reported in previous studies that used a different measure of algal
 biomass, adding guppies and doubling their densities decreased algal
 biovolume through direct effects. In contrast to these previously reported
 results, exchanging guppy phenotypes that live without predators for
 phenotypes that live with predators did not affect algal biovolume.
 Instead, guppies from populations that live with predators increased the
 diversity of algal species and increased GPP compared to guppies that live
 without predators. These changes in the algal community were driven
 primarily by guppy phenotypes that live with predators—algal communities
 in mesocosms without fish were similar to those with guppies from
 predator-free locations, but both were different from mesocosms with
 guppies from populations that live with predators. Changes in the algal
 community were driven directly by differences in foraging behavior between
 the two consumer phenotypes. We reconcile these results with our previous
 findings, thereby enhancing our understanding of the relationship between
 ecological and evolutionary processes.

title: Data from: Adiposity, compared with masculinity, serves as a more valid cue to immunocompetence in human mate choice

description: According to the “good genes” hypothesis, females choose males based on
 traits that indicate the male’s genetic quality in terms of disease
 resistance. The “immunocompetence handicap hypothesis (ICHH)” proposed
 that secondary sexual traits serve as indicators of male genetic quality
 because they indicate that males can contend with the immunosuppressive
 effects of testosterone. Masculinity is commonly assumed to serve as such
 a secondary sexual trait. Yet women do not consistently prefer masculine
 looking men, nor is masculinity consistently related to health across
 studies. Here we show that adiposity, but not masculinity, significantly
 mediates the relationship between a direct measure of immune response
 (Hepatitis B antibody response) and attractiveness for both body and
 facial measurements. In addition, we show that circulating testosterone is
 more closely associated with adiposity than masculinity. These findings
 indicate that adiposity, compared to masculinity, serves as a more
 important cue to immunocompetence in female mate choice.

title: Data from: Individual quality and personality: bolder males are less fecund in the hermit crab Pagurus bernhardus

description: One explanation for animal personality is that different behavioural types
 derive from different life-history strategies. Highly productive
 individuals, with high growth rates and high fecundity, are assumed to
 live life at a fast pace showing high levels of boldness and risk taking,
 compared with less productive individuals. Here, we investigate
 among-individual differences in mean boldness (the inverse of the latency
 to recover from a startling stimulus) and in the consistency of boldness,
 in male hermit crabs in relation to two aspects of life-history
 investment. We assessed aerobic scope by measuring the concentration of
 the respiratory pigment haemocyanin, and we assessed fecundity by
 measuring spermatophore size. First, we found that individuals investing
 in large spermatophores also had high concentrations of haemocyanin. Using
 doubly hierarchical-generalized linear models to analyse longitudinal data
 on startle responses, we show that hermit crabs vary both in their mean
 response durations and in the consistency of their behaviour. Individual
 consistency was unrelated to haemocyanin concentration or spermatophore
 size, but mean startle response duration increased with spermatophore
 size. Thus, counter to expectations, it was the most risk-averse
 individuals, rather than the boldest and most risk prone, that were the
 most productive. We suggest that similar patterns should be present in
 other species, if the most productive individuals avoid risky behaviour.

title: Data from: Species distribution models contribute to determine the effect of climate and interspecific interactions in moving hybrid zones

description: Climate is a major factor delimiting species’ distributions. However,
 biotic interactions may also be prominent in shaping geographical ranges,
 especially for parapatric species forming hybrid zones. Determining the
 relative effect of each factor and their interaction of the contact zone
 location has been difficult due to the lack of broad scale environmental
 data. Recent developments in species distribution modelling (SDM) now
 allow disentangling the relative contributions of climate and species’
 interactions in hybrid zones and their responses to future climate change.
 We investigated the moving hybrid zone between the breeding ranges of two
 parapatric passerines in Europe. We conducted SDMs representing the
 climatic conditions during the breeding season. Our results show a large
 mismatch between the realized and potential distributions of the two
 species, suggesting that interspecific interactions, not climate, account
 for the present location of the contact zone. The SDM scenarios show that
 the southerly distributed species, Hippolais polyglotta, might lose large
 parts of its southern distribution under climate change, but a similar
 gain of novel habitat along the hybrid zone seems unlikely, because
 interactions with the other species (H. icterina) constrain its range
 expansion. Thus, whenever biotic interactions limit range expansion,
 species may become ‘trapped’ if range loss due to climate change is faster
 than the movement of the contact zone. An increasing number of moving
 hybrid zones are being reported, but the proximate causes of movement
 often remain unclear. In a global context of climate change, we call for
 more interest in their interactions with climate change.

title: Data from: Towards the validation of endogenous steroid testing in wildlife hair

description: 1. Hair is emerging as a popular tool to examine steroid hormone levels in
 wild mammals. The reliability of this approach, however, depends on an
 understanding of steroid hormone incorporation into hair as well as
 appropriate validations. 2. We reviewed studies that have examined steroid
 hormones in wildlife hair with the goal of summarizing the analytical,
 physiological, and biological evidence that this approach is meaningful.
 Accordingly, we differentiated among validations aimed at evaluating the
 reliability of the analytical method versus those designed to assess
 whether hormone levels in hair reflect physiologically meaningful
 processes in the target species. 3. Our literature survey revealed that
 endogenous steroids have been examined in hair from 42 species of
 non-human animals across 7 mammalian classes. Although the majority (85%)
 of 72 studies reported analytical validations of the method, physiological
 validations have only been reported for five species. Moreover, results of
 physiological validations were inconsistent among studies, highlighting
 the need for further research designed carefully to differentiate among
 the multiple purported models of steroid incorporation into hair in
 species with different types of hair and hair growth patterns. 4. To
 complement our review of published studies, we present new data supporting
 a positive relationship between levels of the steroid, cortisol, in hair
 and blood across eight mammalian species. In addition, we present novel
 results from a laboratory-based study showing variable hair growth in
 genetically identical laboratory mice that were kept under controlled
 conditions. 5. Synthesis and Applications: Collectively, this synthesis
 reveals substantial progress towards the validation of endocrine assays in
 hair from a variety of wildlife species. Further validations of other
 steroids, combined with appropriate physiological validations, would
 expand the potential applications of hair testing in wildlife research. As
 a key example, physiological data can provide mechanistic insight into
 species’ responses to change and may therefore contribute to conservation
 planning.

title: Data from: Variable light environments induce plastic spectral tuning by regional opsin coexpression in the African cichlid fish, Metriaclima zebra

description: Critical behaviours such as predation and mate choice often depend on
 vision. Visual systems are sensitive to the spectrum of light in their
 environment, which can vary extensively both within and among habitats.
 Evolutionary changes in spectral sensitivity contribute to divergence and
 speciation. Spectral sensitivity of the retina is primarily determined by
 visual pigments, which are opsin proteins bound to a chromophore. We
 recently discovered that photoreceptors in different regions of the
 retina, which view objects against distinct environmental backgrounds,
 coexpress different pairs of opsins in an African cichlid fish,
 Metriaclima zebra. This coexpression tunes the sensitivity of the retinal
 regions to the corresponding backgrounds and may aid in detection of dark
 objects, such as predators. Although intraretinal regionalization of
 spectral sensitivity in many animals correlates with their light
 environments, it is unknown whether variation in the light environment
 induces developmentally plastic alterations of intraretinal sensitivity
 regions. Here, we demonstrate with fluorescent in situ hybridization and
 qPCR that the spectrum and angle of environmental light both influence the
 development of spectral sensitivity regions by altering the distribution
 and level of opsins across the retina. Normally, M. zebra coexpresses LWS
 opsin with RH2Aα opsin in double cones of the ventral but not the dorsal
 retina. However, when illuminated from below throughout development, adult
 M. zebra coexpressed LWS and RH2Aα in double cones both dorsally and
 ventrally. Thus, environmental background spectra alter the spectral
 sensitivity pattern that develops across the retina, potentially
 influencing behaviours and related evolutionary processes such as
 courtship and speciation.
