title: Data from: Two ways to display: male hummingbirds show different color-display tactics based on sun orientation

description: Animals exhibit a diversity of ornaments and courtship behaviors, which
 often co-occur and are used for communication. The sensory drive
 hypothesis states that these traits evolved and vary due to interactions
 with each other, the environment, and signal receiver. However,
 interactions between colorful ornaments and courtship behaviors,
 specifically in relation to environmental variation, remain poorly
 understood. We studied male iridescent plumage (gorgets), display
 behavior, and sun orientation during courtship flights (shuttle displays)
 in broad-tailed hummingbirds (Selasphorus platycercus), to understand how
 these traits interact in both space and time to produce the perceived
 coloration of males. We also tested how gorget coloration varies among
 males based on their plumage, behavioral, and morphological
 characteristics. In contrast with previous work on other animals, we found
 that displaying males did not directionally face the sun, but instead
 displayed on a continuum of solar orientation angles. The gorgets of males
 who tended to face the sun during their displays appeared flashier (i.e.
 exhibited greater color/brightness changes), brighter, and more colorful,
 whereas the gorgets of males who tended to not face the sun were more
 consistently reflective (i.e. little color change) and had greater UV
 reflectance. We found that males who produced consistent colors had larger
 gorgets, whereas males with flashier gorgets were better able to maintain
 their angles of orientation towards the female. Our study illustrates how
 visual traits interact in complex ways with each other and the environment
 and how males of the same species can use multiple tactics to dynamically
 display their coloration.

title: Data from: Partitioning the effects of spatial isolation, nest habitat, and individual diet in causing assortative mating within a population of threespine stickleback

description: Assortative mating is measured as a phenotypic or genotypic correlation
 between mates. Although biologists typically view assortative mating in
 terms of mate preference for similar partners, correlations between mates
 can also arise from phenotypic spatial structure arising from spatial
 isolation or habitat preferences. Here, we test whether diet-assortative
 mating within an ecologically variable population of threespine
 stickleback results from small-scale geographic isolation or microhabitat
 preference. We find evidence for assortative mating in the form of a
 positive correlation between mated pairs’ diets (measured using stable
 isotopes). Stable isotopes reveal diet differences between different
 nesting areas and among individuals using different nest habitat within a
 nesting area. This spatial segregation of diet types should generate some
 assortative mating, but is insufficient to explain the observed assortment
 strength. Significant male-female isotope correlations remain after
 controlling for spatial variables. We therefore conclude that
 sticklebacks' diet-assortative mating arises from additional
 behavioral preference. More generally, our results illustrate the point
 that spatial segregation can only drive appreciable levels of phenotypic
 assortative mating when environment-phenotype correlations are parallel
 and strong in both sexes. Consequently, intraspecific assortative mating
 may typically entail mating preferences rather than just spatial
 co-segregation of phenotypes.

title: Data from: Detrital nutrient content and leaf species differentially affect growth and nutritional regulation of detritivores

description: Resource nutrient content and identity are common bottom-up controls on
 organismal growth and nutritional regulation. One framework to study these
 factors, ecological stoichiometry theory, predicts that elevated resource
 nitrogen (N) and phosphorus (P) contents enhance organism growth by
 alleviating constraints on N and P acquisition. However, the regulatory
 mechanisms underlying this response – including whether responses depend
 on resource identity – remain poorly understood. In this study, we tested
 roles of detrital N and P contents and identity (leaf species) in
 constraining growth of aquatic invertebrate detritivores. We synthesized
 results from seven detritivore species fed wide nutrient gradients of oak
 and maple detritus in the laboratory. Across detritivore taxa, we used a
 meta-analytic approach quantifying effects of detrital leaf species and N
 and P contents on growth, consumption, and N- and P-specific assimilation
 and growth efficiencies. Detritivore growth rates increased on higher-N
 and P detritus and on oak compared to maple detritus. Notably, the
 mechanisms of improved growth differed between the responses to detrital
 nutrients versus leaf species, with the former driven by greater
 consumption rates despite lower assimilation efficiencies on
 higher-nutrient detritus, and the latter driven by improved N and P
 assimilation and N growth efficiencies on oak detritus. These findings
 suggest animal nutrient acquisition changes flexibly in response to
 resource changes, altering the fate of detrital N and P throughout
 regulation. We affirm resource identity and nutrients as important
 bottom-up controls, but suggest these factors act through separate
 pathways to affect organism growth and thereby change detrital ecosystems
 under anthropogenic forest compositional change and nutrient enrichment.

title: Data from: Trophic dynamics of filter feeding bivalves in the Yangtze Estuarine Intertidal Marsh: stable isotope and fatty acid analyses

description: Benthic bivalves are important links between primary production and
 consumers, and are essential intermediates in the flow of energy through
 estuarine systems. However, information on the diet of filter feeding
 bivalves in estuarine ecosystems is uncertain, as estuarine waters contain
 particulate matter from a range of sources and as bivalves are
 opportunistic feeders. We surveyed bivalves at different distances from
 the creek mouth at the Yangtze estuarine marsh in winter and summer, and
 analyzed trophic dynamics using stable isotope (SI) and fatty acid (FA)
 techniques. Different bivalve species had different spatial distributions
 in the estuary. Glauconome chinensis mainly occurred in marshes near the
 creek mouth, while Sinonovacula constricta preferred the creek.
 Differences were found in the diets of different species. S. constricta
 consumed more diatoms and bacteria than G. chinensis, while G. chinensis
 assimilated more macrophyte material. FA markers showed that plants
 contributed the most (38.86 ± 4.25%) to particular organic matter (POM) in
 summer, while diatoms contributed the most (12.68 ± 1.17%) during winter.
 Diatoms made the largest contribution to the diet of S. constricta in both
 summer (24.73 ± 0.44%) and winter (25.51 ± 0.59%), and plants contributed
 no more than 4%. This inconsistency indicates seasonal changes in food
 availability and the active feeding habits of the bivalve. Similar FA
 profiles for S. constricta indicated that the bivalve had a similar diet
 composition at different sites, while different δ13C results suggested the
 diet was derived from different carbon sources (C4 plant Spartina
 alterniflora and C3 plant Phragmites australis and Scirpus mariqueter) at
 different sites. Species-specific and temporal and/or spatial variability
 in bivalve feeding may affect their ecological functions in intertidal
 marshes, which should be considered in the study of food webs and material
 flows in estuarine ecosystems.

title: Data from: Reliability and construct validity of the Psychopathic Personality Inventory-Revised in a Swedish non-criminal sample: a multimethod approach including psychophysiological correlates of empathy for pain

description: Cross-cultural investigation of psychopathy measures is important for
 clarifying the nomological network surrounding the psychopathy construct.
 The Psychopathic Personality Inventory-Revised (PPI-R) is one of the most
 extensively researched self-report measures of psychopathic traits in
 adults. To date however, it has been examined primarily in North American
 criminal or student samples. To address this gap in the literature, we
 examined PPI-R’s reliability, construct validity and factor structure in
 non-criminal individuals (N = 227) in Sweden, using a multimethod approach
 including psychophysiological correlates of empathy for pain. PPI-R
 construct validity was investigated in subgroups of participants by
 exploring its degree of overlap with (i) the Psychopathy Checklist:
 Screening Version (PCL:SV), (ii) self-rated empathy and behavioral and
 physiological responses in an experiment on empathy for pain, and (iii)
 additional self-report measures of alexithymia and trait anxiety. The
 PPI-R total score was significantly associated with PCL:SV total and
 factor scores. The PPI-R Coldheartedness scale demonstrated significant
 negative associations with all empathy subscales and with rated
 unpleasantness and skin conductance responses in the empathy experiment.
 The PPI-R higher order Self-Centered Impulsivity and Fearless Dominance
 dimensions were associated with trait anxiety in opposite directions
 (positively and negatively, respectively). Overall, the results
 demonstrated solid reliability (test-retest and internal consistency) and
 promising but somewhat mixed construct validity for the Swedish
 translation of the PPI-R.

title: Data from: Sensory-based niche partitioning in a multiple predator-multiple prey community

description: Many predators and parasites eavesdrop on the communication signals of
 their prey. Eavesdropping is typically studied as dyadic predator–prey
 species interactions; yet in nature, most predators target multiple prey
 species and most prey must evade multiple predator species. The impact of
 predator communities on prey signal evolution is not well understood.
 Predators could converge in their preferences for conspicuous signal
 properties, generating competition among predators and natural selection
 on particular prey signal features. Alternatively, predator species could
 vary in their preferences for prey signal properties, resulting in
 sensory-based niche partitioning of prey resources. In the Neotropics,
 many substrate-gleaning bats use the mate-attraction songs of male
 katydids to locate them as prey. We studied mechanisms of niche
 partitioning in four substrate-gleaning bat species and found they are
 similar in morphology, echolocation signal design and prey-handling
 ability, but each species preferred different acoustic features of male
 song in 12 sympatric katydid species. This divergence in predator
 preference probably contributes to the coexistence of many
 substrate-gleaning bat species in the Neotropics, and the substantial
 diversity in the mate-attraction signals of katydids. Our results provide
 insight into how multiple eavesdropping predator species might influence
 prey signal evolution through sensory-based niche partitioning.

title: Data from: Lack of spatial structure for phenotypic and genetic variation despite high self-fertilization in Aquilegia canadensis (Ranunculaceae)

description: By reducing genetically effective population size and gene flow,
 self-fertilization should lead to strong spatial genetic structure (SGS).
 Although the short-lived plant Aquilegia canadensis produces large,
 complex, nectar-rich flowers, 75% of seed, on average, are
 self-fertilized. Previous experimental results are consistent with the
 fine-scale SGS expected in selfing populations. In contrast, key floral
 traits show no evidence of SGS, despite a significant genetic basis to
 phenotypic variation within populations. In this study, we attempt to
 resolve these contradictory results by hierarchically sampling plants from
 two plots nested within each of seven rock outcrops distributed over
 several km, and comparing the spatial pattern of phenotypic variation in
 four floral traits with neutral genetic variation at 10 microsatellite
 loci. For both floral and microsatellite variation, we detected only weak
 hierarchical structuring and no isolation by distance. The spatial pattern
 of variation in floral traits was on par with microsatellite
 polymorphisms. These results suggest regular long-distance gene flow via
 pollen. At much finer spatial scales within plots, estimates of
 relatedness were higher (albeit very low) between nearest neighbours than
 random plants, and declined with increasing distance between neighbours,
 consistent with highly localized seed dispersal. High selfing should yield
 SGS, but strong inbreeding depression in A. canadensis likely erodes SGS
 so that reproductive plants exhibit weak structure typical of outcrossers,
 especially given that outcrossing and consequent gene flow in this species
 are mediated by strong-flying hummingbirds and bumble bees.
description: HierstructWe present morphological and genotypic observations for plants observed in the field. Individuals were sampled hierarchically from two plots nested within each of seven rock outcrops distributed over several km. Phenotypic variation in four floral traits was compared with neutral genetic variation at microsatellite loci (9 loci used for AMOVA type analyses and 10 loci used for nearest-neighbour analysis). Six data files are contained within this project.

title: Data from: Are species differences in maternal effects arising from maternal care adaptive?

description: Parental care benefits offspring through maternal effects influencing
 their development, growth and survival. However, although parental care in
 general is likely the result of adaptive evolution, it does not follow
 that specific differences in the maternal effects that arise from care are
 also adaptive. Here, we used an interspecific cross-fostering design in
 the burying beetle species Nicrophorus orbicollis and N. vespilloides,
 both of which have elaborate parental care involving direct feeding of
 regurgitated food to offspring, to test whether maternal effects are
 optimized within a species and therefore adaptive. Using a full-factorial
 design, we first demonstrated that N. orbicollis care for offspring longer
 regardless of recipient species. We then examined offspring development
 and mass in offspring reared by hetero- or conspecific parents. As
 expected, there were species-specific direct effects independent of the
 maternal effects, as N. orbicollis larvae were larger and took longer to
 develop than N. vespilloides regardless of caregiver. We also found
 significant differences in maternal effects: N. vespilloides maternal care
 caused more rapid development of offspring of either species. Contrary to
 expectations if maternal effects were species-specific, there were no
 significant interactions between caretaker and recipient species for
 either development time or mass, suggesting that these maternal effects
 are general rather than optimized within species. We suggest that rather
 than coadaptation between parents and offspring performance, the species
 differences in maternal effects may be correlated with direct effects, and
 that their evolution is driven by selection on those direct effects.

title: Data from: Trichobaris weevils distinguish amongst toxic host plants by sensing volatiles that do not affect larval performance

description: Herbivorous insects use plant metabolites to inform their host plant
 selection for oviposition. These host-selection behaviours are often
 consistent with the preference–performance hypothesis; females oviposit on
 hosts that maximize the performance of their offspring. However, the
 metabolites used for these oviposition choices and those responsible for
 differences in offspring performance remain unknown for ecologically
 relevant interactions. Here, we examined the host-selection behaviours of
 two sympatric weevils, the Datura (Trichobaris compacta) and tobacco (T.
 mucorea) weevils in field and glasshouse experiments with transgenic host
 plants specifically altered in different components of their secondary
 metabolism. Adult females of both species strongly preferred to feed on D.
 wrightii rather than on N. attenuata leaves, but T. mucorea preferred to
 oviposit on N. attenuata, while T. compacta oviposited only on D.
 wrightii. These oviposition behaviours increased offspring performance: T.
 compacta larvae only survived in D. wrightii stems and T. mucorea larvae
 survived better in N. attenuata than in D. wrightii stems. Choice assays
 with nicotine-free, JA-impaired, and sesquiterpene-over-produced isogenic
 N. attenuata plants revealed that although half of the T. compacta larvae
 survived in nicotine-free N. attenuata lines, nicotine did not influence
 the oviposition behaviours of both the nicotine-adapted and
 nicotine-sensitive species. JA-induced sesquiterpene volatiles are key
 compounds influencing T. mucorea females’ oviposition choices, but these
 sesquiterpenes had no effect on larval performance. We conclude that adult
 females are able to choose the best host plant for their offspring and use
 chemicals different from those that influence larval performance to inform
 their oviposition decisions.

title: Data from: Maternal diet and age alter direct and indirect relationships between life history traits across multiple generations

description: 1. Maternal age has important consequences for offspring fitness, with
 influences on size, development, and reproductive schedules. Such maternal
 age effects may be driven by differential provisioning of resources, yet
 little is known about the role of environmental supply of nutritional
 resources in mediating such effects. 2. We tested the influence of
 limiting nutritional resource, dietary phosphorus (P), on maternal age
 effects across multiple generations by examining the potential interactive
 effects of maternal nutrition and age on daughter and granddaughter life
 history traits in the freshwater crustacean Daphnia pulicaria. 3. Maternal
 age and diet had significant but contrasting effects on offspring life
 history. We did not observe any evidence that age effects on offspring
 life history are mediated by maternal diet. However, granddaughter growth
 and size at maturation were influenced by the interaction between
 grandmaternal age and diet, suggesting that the appearance of
 transgenerational effects of age and diet were delayed by one generation.
 4. Because offspring life history is often linked directly and/or
 indirectly to life history variation in previous generations, we utilized
 structural equation modeling (SEM) to assess such direct or indirect
 relationships. 5. SEM revealed striking differences in the relationship
 between growth, development time, and fecundity both within and among
 generations, depending on the age and diet in the F0 generation.
 Interestingly, direct and persistent relationships between the F0
 generation and the F2 generation are most prevalent when grandmothers are
 old and fed low P diets, and such relationships are largely driven by
 fecundity in the F0 generation. Additionally, indirect causal
 relationships between the F0 generation and F2 generation are most
 pronounced when grandmothers are young and fed low P diets or when
 grandmothers are old and fed high P diets. 6. Our results indicate that
 transgenerational effects of maternal age and environment persist across
 multiple generations, and vary between successive generations. Further,
 our examination of the interaction network between life history traits of
 each generation suggest that the mechanisms for such persistent
 transgenerational effects are highly dependent on maternal condition.
