title: Data from: The influence of data resolution on predicted distribution and estimates of extent of current protection of three ‘listed’ deep-sea habitats

description: Modelling approaches have the potential to significantly contribute to the
 spatial management of the deep-sea ecosystem in a cost effective manner.
 However, we currently have little understanding of the accuracy of such
 models, developed using limited data, of varying resolution. The aim of
 this study was to investigate the performance of predictive models
 constructed using non-simulated (real world) data of different resolution.
 Predicted distribution maps for three deep-sea habitats were constructed
 using MaxEnt modelling methods using high resolution multibeam bathymetric
 data and associated terrain derived variables as predictors. Model
 performance was evaluated using repeated 75/25 training/test data
 partitions using AUC and threshold-dependent assessment methods. The
 overall extent and distribution of each habitat, and the percentage
 contained within an existing MPA network were quantified and compared to
 results from low resolution GEBCO models. Predicted spatial extent for
 scleractinian coral reef and Syringammina fragilissima aggregations
 decreased with an increase in model resolution, whereas Pheronema
 carpenteri total suitable area increased. Distinct differences in
 predicted habitat distribution were observed for all three habitats.
 Estimates of habitat extent contained within the MPA network all increased
 when modelled at fine scale. High resolution models performed better than
 low resolution models according to threshold-dependent evaluation. We
 recommend the use of high resolution multibeam bathymetry data over low
 resolution bathymetry data for use in modelling approaches. We do not
 recommend the use of predictive models to produce absolute values of
 habitat extent, but likely areas of suitable habitat. Assessments of MPA
 network effectiveness based on calculations of percentage area protection
 (policy driven conservation targets) from low resolution models are likely
 to be fit for purpose.

title: Data from: Habitat-driven life history variation in an amphibian metapopulation

description: Life-history theory states that, during the lifetime of an individual,
 resources are allocated to either somatic maintenance or reproduction.
 Resource allocation trade-offs determine the evolution and ecology of
 life-history strategies and determine an organisms’ position along the
 fast-slow continuum. Theory predicts that environmental stochasticity is
 an important driver of resource allocation and therefore life-history
 evolution. Highly stochastic environments are expected to increase
 uncertainty in reproductive success and select for iteroparity and a
 slowing down of the life history. To date, most empirical studies have
 used comparisons among species to examine these theoretical predictions.
 By contrast, few have investigated how environmental stochasticity affects
 life-history strategies at the intraspecific level. In this study, we
 examined how variation in breeding site stochasticity (among-year
 variability in pond volume and hydroperiod) promotes the co-occurrence of
 different life-history strategies in a spatially structured population,
 and determines life-history position along the fast-slow continuum in the
 yellow-bellied toad (Bombina variegata). We collected mark-recapture data
 from a metapopulation and used multievent capture-recapture models to
 estimate survival, recruitment and breeding probabilities. We found higher
 survival and longer lifespans in populations inhabiting variable sites
 compared to those breeding in stable ones. In addition, probabilities of
 recruitment and skipping a breeding event were higher in variable sites.
 The temporal variance of survival and recruitment probabilities, as well
 as the probability to skip breeding, was higher in variable sites. Taken
 together, these findings indicate that populations breeding in variable
 sites experienced a slowing down of the life-history. Our study thus
 revealed similarities in the macroevolutionary and microevolutionary
 processes shaping life-history evolution.

title: Data from: Phenotypic and community consequences of captive propagation in mosquitofish

description: 1. Captive propagation can lead to phenotypic change in fish populations,
 but the broader community-level consequences of captive phenotypes remain
 largely unknown. 2. Here we investigate the degree to which captive
 propagation alters the phenotypes and ecological roles of fish stocked
 into wild communities. We focus on captive propagation of western
 mosquitofish (Gambusia affinis) for biocontrol, which represents one of
 the largest-scale production efforts for any fish released into the wild.
 3. Captive propagation in mosquitofish consistently generated novel
 mixtures of morphological and behavioral traits that deviate from those of
 wild populations. 4. A mesocosm experiment showed that mosquitofish from
 captive propagation facilities differ from wild fish in their effects on
 aquatic community structure by shifting their consumption to less-mobile,
 benthic prey. 5. Synthesis and applications: These findings provide
 evidence that captive-propagated and translocated wild stocks not only
 differ in phenotype, but can have substantially different ecological
 effects on the communities into which they are introduced. Therefore,
 captive propagation programs involving continual release should expand
 their concerns beyond altered phenotypes and fitness to include whether
 propagated fish actually provide the intended ecological roles and
 services associated with wild counterparts. Infusions of wild alleles and
 captive environments that mimic wild conditions are recommended strategies
 to retain the desired ecological role of captive propagated fish

title: Data from: Sperm head abnormalities are more frequent in songbirds with more helical sperm: A possible trade-off in sperm evolution

description: Sperm morphology varies enormously across the animal kingdom. While
 knowledge of the factors that drive the evolution of interspecific
 variation in sperm morphology is accumulating, we currently have little
 understanding of factors that may constrain evolutionary change in sperm
 traits. We investigated whether susceptibility to sperm abnormalities
 could represent such a constraint in songbirds, a group characterised by a
 distinctive helical sperm head shape. Specifically, using 36 songbird
 species and data from light- and scanning electron microscopy, we examined
 among-species correlations between the occurrence of sperm head
 abnormalities and sperm morphology, as well as the correlation between
 sperm head abnormalities and two indicators of sperm competition. We found
 that species with more helically shaped sperm heads (i.e. a wider helical
 membrane and more pronounced cell waveform) had a higher percentage of
 abnormal sperm heads than species with less helical sperm (i.e. relatively
 straight sperm), and that sperm head traits were better predictors of head
 abnormalities than total sperm length. In contrast, there was no
 correlation between sperm abnormalities and the level of sperm
 competition. Given that songbird species with more pronounced helical
 sperm have higher average sperm swimming speed, our results suggest an
 evolutionary trade-off between sperm performance and the structural
 integrity of the sperm head. As such, susceptibility to morphological
 abnormalities may constrain the evolution of helical sperm morphology in
 songbirds.

title: Data from: Nuclear microsatellite and mitochondrial DNA analyses reveal the regional genetic structure and phylogeographical history of a sanguivorous land leech, Haemadipsa japonica, in Japan

description: Recent molecular studies have indicated that phylogeographical history of
 Japanese biota is likely shaped by geohistory along with biological
 events, such as distribution shifts, isolation, and divergence of
 populations. However, the genetic structure and phylogeographical history
 of terrestrial Annelida species, including leech species, are poorly
 understood. Therefore, we aimed to understand the genetic structure and
 phylogeographical history across the natural range of Haemadipsa japonica,
 a sanguivorous land leech species endemic to Japan, by using nine
 polymorphic nuclear microsatellites (nSSR) and cytochrome oxidase subunit
 one (COI) sequences of mitochondrial DNA (mtDNA). Analyses using nSSR
 revealed that H. japonica exhibited a stronger regional genetic
 differentiation among populations (G'ST = 0.77) than other animal
 species, probably because of the low mobility of land leech. Analyses
 using mtDNA indicated that H. japonica exhibited two distinct lineages (A
 and B), which were estimated to have diverged in the middle Pleistocene
 and probably because of range fragmentation resulting from climatic change
 and glacial and interglacial cycles. Lineage A was widely distributed
 across Japan, and lineage B was found in southwestern Japan. Analyses
 using nSSR revealed that lineage A was roughly divided into two population
 groups (i.e., northeastern and southwestern Japan); these analyses also
 revealed a gradual decrease in genetic diversity with increasing latitude
 in lineage A and a strong genetic drift in populations of northeastern
 Japan. Combined with the largely unresolved shallow polytomies from the
 mtDNA phylogeny, these results implied that lineage A may have undergone a
 rapid northward migration, probably during the Holocene. Then, the
 regional genetic structure with local unique gene pools may have been
 formed within each lineage because of the low mobility of this leech
 species.

title: Data from: Temperature-dependence of minimum resource requirements alters competitive hierarchies in phytoplankton

description: 1. Resource competition theory is a conceptual framework that provides
 mechanistic insights into competition and community assembly of species
 with different resource requirements. However, there has been little
 exploration of how resource requirements depend on other environmental
 factors, including temperature. Changes in resource requirements as
 influenced by environmental temperature would imply that climate warming
 can alter the outcomes of competition and community assembly. 2. We
 experimentally demonstrate that environmental temperature alters the
 minimum light and nitrogen requirements – as well as other growth
 parameters – of six widespread phytoplankton species from distinct
 taxonomic groups. We found that species require the most nitrogen at the
 highest temperatures while light requirements tend to be lowest at
 intermediate temperatures, although there are substantial interspecific
 differences in the exact shape of this relationship. 3. We also
 experimentally parameterize two competition models, which we use to
 illustrate how temperature, through its effects on species’ traits, alters
 competitive hierarchies in multispecies assemblages, determining community
 dynamics. 4. Developing a mechanistic understanding of how temperature
 influences the ability to compete for limiting resources is a critical
 step towards improving forecasts of community dynamics under climate
 warming.

title: Data from: Effect of plant chemical variation and mutualistic ants on the local population genetic structure of an aphid herbivore

description: 1.Plants exhibit impressive genetic and chemical diversity, not just
 between species but also within species, and the importance of plant
 intraspecific variation for structuring ecological communities is well
 known. When there is variation at the local population level, this can
 create a spatially‐heterogeneous habitat for specialized herbivores
 potentially leading to non‐random distribution of individuals across
 host‐plants. 2.Plant variation can affect herbivores directly and
 indirectly via a third species, resulting in variable herbivore growth
 rates across different host plants. Herbivores also exhibit within‐species
 variation, with some genotypes better adapted to some plant variants than
 others. 3.We genotyped aphids collected across two years from a field site
 containing ~200 patchily‐distributed host plants that exhibit high
 chemical diversity. The distribution of aphid genotypes, their ant
 mutualists, and other predators was assessed across the plants. 4.We
 present evidence that the local distribution of aphid (Metopeurum
 fuscoviride) genotypes across host‐plant individuals is associated with
 variation in the plant volatiles (chemotypes) and non‐volatile metabolites
 (metabotypes) of their host plant tansy (Tanacetum vulgare). Furthermore,
 these interactions in the field were influenced by plant‐host preferences
 of aphid‐mutualist ants. 5.Our results emphasize that plant intraspecific
 variation can structure ecological communities not only at the species
 level but also at the genetic level within species, and that this effect
 can be enhanced through indirect interactions with a third species.

title: Data from: Seasonal variation in food availability and relative importance of dietary items in the Gambian epauletted fruit bat (Epomophorus gambianus)

description: 1. The Gambian epauletted fruit bat (Epomophorus gambianus) is very common
 across a variety of West African habitats, but very little information is
 available on its feeding ecology or its contribution to ecosystem
 function. 2. We investigated seasonal variation in food availability and
 the relative importance of dietary items used by this species in a
 forest-savannah transitional ecosystem. Dietary items were identified from
 1,470 samples of faecal and ejecta pellets which had been collected under
 day roosts or from captured bats over a two year period (2014-2015). 3.
 Plant phenology studies illustrated strong seasonal correlations between
 fruiting and flowering and rainfall patterns: fruits were available
 throughout the year but with peaks of abundance during the rainy season,
 while flowers were mostly abundant during the dry season. Epomophorus
 gambianus bats utilized fruit and flower resources from 30 plant species.
 Although the plant species used depended on seasonal availability, there
 were clear preferences for certain species. 4. Flowers were an important
 food source for this fruit bat species especially during the dry season,
 contributing up to 79% of dietary items when fruit abundance was low.
 Ficus fruits were also important food item for E. gambianus, constituting
 over 40% of all dietary samples identified. 5. Policy implications. Our
 results show the importance of flowers in the diet of E. gambianus, and
 highlight this species as an important pollinator and seed disperser,
 including for economically and ecologically important plant species. These
 findings contribute to an improved understanding of the ecological
 importance and potential role of this species in the forest-savannah
 transition ecosystem for the development of fruit bat conservation
 management strategies.

title: Data from: Native forage mediates influence of irrigated agriculture on migratory behavior of elk

description: 1. Ungulates migrate to maximize nutritional intake when forage varies
 seasonally. Populations of ungulates often include both migratory and
 non-migratory individuals, but the mechanisms driving individual
 differences in migratory behavior are not well-understood. 2. We
 quantified associations between hypothesized drivers of partial migration
 and the likelihood of migration for individual ungulates that experienced
 a range of environmental conditions and anthropogenic influences. 3. We
 evaluated the effects of forage variation, conspecific density, and human
 land uses on migratory behavior of 308 adult female elk in 16 herds across
 western Montana. 4. We found irrigated agriculture on an individual’s
 winter range reduced migratory behavior, but individuals were more likely
 to migrate away from irrigated agricultural areas if better forage was
 available elsewhere or if they experienced high conspecific density on
 their winter range. When the forage available during the summer growing
 season varied predictably between years, elk were more likely to migrate
 regardless of whether they had access to irrigated agriculture. 5. Our
 study shows that predictable availability of beneficial native forage can
 encourage migration even for ungulates with irrigated agriculture on their
 winter range. Perturbations that can affect the forage available to
 ungulates include wildfires, timber harvest, livestock grazing, and
 changing weather patterns. If these or other disturbances negatively
 affect forage on summer ranges of migrants, or if they cause forage to
 vary unpredictably across space and time, our results suggest migratory
 behavior may decline as a result.

title: Data from: Contrasting impacts of precipitation on Mediterranean birds and butterflies

description: The climatic preferences of the species determine to a large extent their
 response to climate change. Temperature preferences have been shown to
 play a key role in driving trends in animal populations. However, the
 relative importance of temperature and precipitation preferences is still
 poorly understood, particularly in systems where ecological processes are
 strongly constrained by the amount and timing of rainfall. In this study,
 we estimated the role played by temperature and precipitation preferences
 in determining population trends for birds and butterflies in a
 Mediterranean area. Trends were derived from long-term biodiversity
 monitoring data and temperature and precipitation preferences were
 estimated from species distribution data at three different geographical
 scales. We show that population trends were first and foremost related to
 precipitation preferences both in birds and in butterflies. Temperature
 preferences had a weaker effect on population trends, and were significant
 only in birds. The effect of precipitation on population trends operated
 in opposite directions in the two groups of species: butterfly species
 from arid environments and bird species from humid habitats are decreasing
 most. Our results indicate that, although commonly neglected, water
 availability is likely an important driver of animal population change in
 the Mediterranean region, with highly contrasting impacts among
 taxonomical groups.
