title: Data from: Environmental constraints and call evolution in torrent dwelling frogs

description: While acoustic signals are important for communication in many taxa,
 signal propagation is affected by environmental properties. Strong
 environmental constraints should drive call evolution, favoring signals
 with greater transmission distance and content integrity in a given
 calling habitat. Yet, few empirical studies have verified this prediction,
 possibly due to a shortcoming in habitat characterization, which is often
 too broad. Here we assess the potential impact of environmental
 constraints on the evolution of advertisement call in four groups of
 torrent dwelling frogs in the family Ranidae. We reconstruct the evolution
 of calling site preferences, both broadly categorized and at a finer
 scale, onto a phylogenetic tree for 148 species with five markers (∼ 3600
 bp). We test models of evolution for six call traits for 79 species with
 regard to the reconstructed history of calling site preferences and
 estimate their ancestral states. We find that in spite of existing
 morphological constraints, vocalizations of torrent dwelling species are
 most probably constrained by the acoustic specificities of torrent
 habitats and particularly their high level of ambient noise. We also show
 that a fine-scale characterization of calling sites allows a better
 perception of the impact of environmental constraints on call evolution.

title: Data from: Do wolf spiders' egg-sacs emit tactochemical signals perceived by mothers?

description: Parent-offspring relationships take many forms. One particular form of
 parental behaviour is egg care when parents brood their eggs after laying
 them. Parents of many oviparous vertebrates and terrestrial arthropods
 brood their eggs. Spiders present a particular interesting form of
 parental behaviour, enclosing their eggs in a silk sac (or egg-sac) and
 can care for it until spiderlings emerge. This study investigated proximal
 cues which stimulate the wolf spider Pardosa saltans (Lycosidae) to care
 for their egg-sacs, transport it for 30 days and open it to allow
 spiderlings to emerge. We showed that mothers discriminate between
 egg-sacs differencing in mass (empty or not) as they do not hang an empty
 egg-sac but do not discriminate between egg-sacs with viable and nonviable
 juveniles either when manipulating or when hanging them. However, mothers
 do not open nonviable egg-sacs but abandon them only at the end of the
 juvenile development period when spiderlings are due to emerge (30-day-old
 egg-sacs). We investigated egg-sac silk chemical cues that mothers
 detected by presenting them egg-sacs washed with different polar solvents
 or chemical egg-sacs silk extracts. We identified the polar and apolar
 chemical compounds of lipid extracts of egg-sacs detected by mothers
 during manipulation. Our results demonstrate that these compounds
 stimulate maternal care, and mothers detect mobility of juveniles at the
 end of the post-embryonic period, when juveniles are ready to emerge from
 a 30-day-old egg-sac indicating that tactochemical stimuli are involved in
 egg-sac care.

title: Data from: How to estimate kinship

description: The concept of kinship permeates many domains of fundamental and applied
 biology ranging from social evolution to conservation science to
 quantitative and human genetics. Until recently, pedigrees were the gold
 standard to infer kinship, but the advent of next generation sequencing
 and the availability of dense genetic markers in many species make it a
 good time to (re) evaluate the usefulness of genetic markers in this
 context. Using three published data sets where both pedigrees and markers
 are available, we evaluate two common and a new genetic estimator of
 kinship. We show discrepancies between pedigree values and marker
 estimates of kinship, and explore via simulations the possible reasons for
 these. We find these discrepancies are attributable to two main sources:
 pedigree errors and heterogeneity in the origin of founders. We also show
 that our new marker-based kinship estimator has very good statistical
 properties and behavior, and is particularly well suited for situations
 where the source population is of small size, as will often be the case in
 conservation biology, and where high levels of kinship are expected, as is
 typical in social evolution studies.

title: Data from: Species abundance, not diet breadth, drives the persistence of the most linked pollinators as plant-pollinator networks disassemble

description: Theoretical and simulation studies predict that the order of species loss
 from mutualist networks, with respect to how linked species are to other
 species within the network, will determine the rate at which networks
 collapse. However, the empirical order of species loss with respect to
 linkage has rarely been investigated. Furthermore, a species' linkage
 is a composite of its diet breadth and its abundance, yet the relative
 importance of these two factors in determining species loss order is
 poorly known. Here we explore the order of pollinator species loss in two
 contrasting study systems, both undergoing land-use intensification, using
 a total of &gt;20,000 pollinator specimens. We found that a pollinator
 species' linkage, as measured independently within plant-pollinator
 networks, positively predicted its persistence at human-disturbed sites in
 three of four analyses. The strongest predictor of persistence in all
 analyses was pollinator species' abundance. In contrast, diet breadth
 poorly predicted persistence. Overall, our results suggest that community
 disassembly order buffers plant-pollinator networks against environmental
 change by retaining the highly linked species that make a disproportionate
 contribution to network robustness. Furthermore, these highly linked
 species likely persist because they are also the most common species, not
 because they are dietary generalists.

title: Data from: Oviposition site choice under conflicting risks demonstrates that aquatic predators drive terrestrial egg-laying

description: Laying eggs out of water was crucial to the transition to land and has
 evolved repeatedly in multiple animal phyla. However, testing hypotheses
 about this transition has been difficult because extant species only breed
 in one environment. The pantless treefrog, Dendropsophus ebraccatus, makes
 such tests possible because they lay both aquatic and arboreal eggs. Here,
 we test the oviposition site choices of D. ebraccatus under conflicting
 risks of arboreal egg desiccation and aquatic egg predation, thereby
 estimating the relative importance of each selective agent on
 reproduction. We also measured discrimination between habitats with and
 without predators and development of naturally laid aquatic and arboreal
 eggs. Aquatic embryos in nature developed faster than arboreal embryos,
 implying no cost to aquatic egg laying. In choice tests, D. ebraccatus
 avoided habitats with fish, showing that they can detect aquatic egg
 predators. Most importantly, D. ebraccatus laid most eggs in the water
 when faced with only desiccation risk, but switched to laying eggs
 arboreally when desiccation risk and aquatic predators were both present.
 This provides the first experimental evidence to our knowledge that
 aquatic predation risk influences non-aquatic oviposition and strongly
 supports the hypothesis that it was a driver of the evolution of
 terrestrial reproduction.

title: Data from: Evaluating environmental DNA-based quantification of ranavirus infection in wood frog populations

description: A variety of challenges arise when monitoring wildlife populations for
 disease. Sampling tissues can be invasive to hosts, and obtaining
 sufficient sample sizes can be expensive and time-consuming, particularly
 for rare species and when pathogen prevalence is low. Environmental DNA
 (eDNA)-based detection of pathogens is an alternative approach to
 surveillance for aquatic communities that circumvents many of these
 issues. Ranaviruses are emerging pathogens of ectothermic vertebrates
 linked to die-offs of amphibian populations. Detecting ranavirus
 infections is critical, but nonlethal methods have the above issues and
 are prone to false negatives. We report on the feasibility and
 effectiveness of eDNA-based ranavirus detection in the field. We compared
 ranavirus titres in eDNA samples collected from pond water to titres in
 wood frog (Lithobates sylvaticus; n = 5) tadpoles in sites dominated by
 this one species (n = 20 pond visits). We examined whether ranavirus DNA
 can be detected in eDNA from pond water when infections are present in the
 pond and if viral titres detected in eDNA samples correlate with the
 prevalence or intensity of ranavirus infections in tadpoles. With three
 250 mL water samples, we were able to detect the virus in all visits with
 infected larvae (0.92 diagnostic sensitivity). Also, we found a strong
 relationship between the viral eDNA titres and titres in larval tissues.
 eDNA titres increased prior to observed die-offs and declined afterwards,
 and were two orders of magnitude higher in ponds with a die-off. Our
 results suggest that eDNA is useful for detecting ranavirus infections in
 wildlife and aquaculture.

title: Data from: A melanin-based trait is more strongly related to body size in the tropics than in temperate regions in the globally distributed barn owl family

description: Life history traits differ between organisms living in the tropics,
 northern and southern hemispheres, and sexual selection is thought to be
 stronger close to the equator than in temperate regions. Although birds
 are often supposed to be more brightly coloured in the tropics, the
 current evidence of geographic variation in the intensity of sexual
 selection and sex-specific natural selection is equivocal. Whether
 sex-specific traits signal aspects of individual quality better in the
 tropics than in the temperate regions of the northern and southern
 hemispheres therefore remains an open question. We examined predictions of
 this hypothesis in the Tytonidae family (barn owls and their relatives)
 because females, on average, display larger black spots on the tip of
 their ventral body feathers than males, and this trait is associated with
 aspects of individual quality. We measured the size of melanic spots and
 the wing length of 7893 Tytonidae skins collected worldwide and preserved
 in natural history museums. The covariation between spot size and wing
 length was stronger in females than in males, in large- than small-spotted
 Tyto taxa and close to the equator than in temperate regions. This
 suggests that selection for spot size, which can be used by owls as an
 additional cue to assess individual body size and other aspects of
 phenotypic quality, is stronger in females than in males, particularly
 near the equator.

title: Data from: Exploring temporal patterning of psychological skills usage during the week leading up to competition: lessons for developing intervention programmes

description: Background and purpose: Although sport psychology literature focuses on
 psychological skills use to promote proficiency, it is still puzzling that
 current research has focused on psychological skills use only during
 competition. There remains a scarcity of empirical evidence to support the
 timing, and content of psychological skill application during the time
 preceding competition. This study examined the extent to which
 psychological skills usage are dynamic or stable over a 7-day
 pre-competitive period and whether any natural learning experiences might
 have accounted for the acquisition of these skills across gender and skill
 level. Methods and results: Ninety elite and semi-elite table tennis
 players completed the Test of Performance Strategies (TOPS) at three
 different periods (7 days, 2 days, 1hour) before competition. A MANOVA
 repeated measures with follow-up analyses revealed significant
 multivariate main effects for only skill level and time-to-competition
 with no interactions. Specifically, elite (international) athletes
 reported more usage than semi-elite (national) counterparts for self-talk,
 imagery and relaxation respectively. Time-to-competition effects showed
 imagery use decreased steadily across the three time points while reported
 usage of relaxation were almost at the same level on two time points (7
 days and 1 hour) but decreased 2 days before competition. Conclusions:
 Findings suggest an implementation of formalized and periodized
 psychological skills training programs over continuous training cycles.
 This may foster a positive long-term athletes' psychological state
 prior to the onset of competition.

title: Data from: Changes in horn size of Stone's sheep over four decades correlate with trophy hunting pressure

description: Selective harvest may lead to rapid evolutionary change. For large
 herbivores, trophy hunting removes males with large horns. That artificial
 selection, operating in opposition to sexual selection, can lead to
 undesirable consequences for management and conservation. There have been
 no comparisons of long-term changes in trophy size under contrasting
 harvest pressures. We analyzed horn measurements of Stone's rams
 (Ovis dalli stonei) harvested over 37 years in two large regions of
 British Columbia, Canada, with marked differences in hunting pressure to
 identify when selective hunting may cause a long-term decrease in horn
 growth. Under strong selective harvest, horn growth early in life and the
 number of males harvested declined respectively by 12% and 45% over the
 study period. Horn shape also changed over time: horn length became
 shorter for a given base circumference, likely because horn base is not a
 direct target of hunter selection. In contrast, under relatively lower
 hunting pressure, there were no detectable temporal trends in early horn
 growth, number of males harvested or horn length relative to base
 circumference. Trophy hunting is an important recreational activity and
 can generate substantial revenues for conservation. By providing a
 reproductive advantage to males with smaller horns and reducing the
 availability of desirable trophies, however, excessive harvest may have
 the undesirable long-term consequences of reducing both the harvest and
 the horn size of rams. These consequences can be avoided by limiting
 offtake.

title: Data from: Macronutrient selection of free-ranging urban Australian white ibis (Threskiornis moluccus)

description: Anthropogenic habitats often provide urban wildlife the opportunity to
 feed on a range of nutritionally diverse foods, which may ultimately lead
 to human-wildlife conflict. The Australian white ibis (Threskiornis
 moluccus) provides an exemplar model for examining the nutritional
 priorities and constraints of a native vertebrate that is successfully
 transitioning to an urban specialist. Here, we used field-based feeding
 trials to investigate the macronutrient preferences of free-ranging ibis
 in Sydney, Australia. Feeding trials (n = 61) offering three experimental
 feeds showed that ibis selected significantly more high-carbohydrate (HC)
 than high-protein (HP) and high-lipid (HL) foods (95% CIHP-HC = −1.115 to
 −0.709; CIHL-HC = −1.874 to −1.468), and significantly more HP than HL
 (CIHL-HP = −0.962 to −0.556). The average proportion of
 macronutrient-derived energy selected by ibis was 25% protein (P; ± 1.1
 SE): 23% lipid (L; ± 1.1): 52% carbohydrate (C; ± 1.8). Nutritional
 geometry suggested that mixtures selected at experimental feeders were
 substantially higher in C and lower in P than are natural prey (e.g.
 insects, crustaceans), which were composed primarily of P and L.
 Compositional log-ratio-based linear models of factors affecting
 macronutrient proportions selected by ibis showed that: 1) ln(P/C)
 increased with amount of recent rainfall; and 2) ln(L/C) also increased
 with rain and had a non-linear relationship with number of birds feeding.
 Our results suggest that ibis forage for macronutrients rather than energy
 “per se”, and that their urban foraging is influenced by competition and
 the environment.

title: Data from: Cenozoic colonization and diversification patterns of tropical American palms: evidence from Astrocaryum (Arecaceae)

description: With 788 species in 67 genera in the Neotropics, Arecaceae are an
 important ecological and economic component of the region. We review the
 influence of geological events such as the Pebas system, the Andean uplift
 and the land connections between South and Central/North America, on the
 historical assembly of Neotropical palms. We present a case study of the
 palm genus Astrocaryum (40 species) as a model for evaluating colonization
 and diversification patterns of lowland Neotropical taxa. We conducted a
 Bayesian dated phylogenetic analysis based on four low-copy nuclear DNA
 regions and a biogeographical analysis using the dispersal, extinction and
 cladogenesis model. Cladogenesis of Western Amazonian Astrocaryum spp.
 (c. 6 Mya) post-dated the drainage of the aquatic Pebas system, supporting
 the constraining role of Pebas on in situ diversification and
 colonization. The ancestral distribution of Astrocaryum spp. in the Guiana
 Shield supported the hypothesis of an old formation that acted as a source
 area from which species colonized adjacent regions, but an earliest
 branching position for Guianan species was not confidently recovered. A
 twofold increase in diversification rate was found in a clade, the
 ancestor of which occupied the Guiana Shield (c. 13 Mya, a time of
 climatic change and Andean uplift).

title: Data from: Etiology of respiratory tract infections in the community and clinic in Ilorin, Nigeria

description: Objective: Recognizing increasing interest in community disease
 surveillance globally, the goal of this study was to investigate whether
 respiratory viruses circulating in the community may be represented
 through clinical (hospital) surveillance in Nigeria. Results: Children
 were selected via convenience sampling from communities and a tertiary
 care center (n = 91) during spring 2017 in Ilorin, Nigeria. Nasal swabs
 were collected and tested using polymerase chain reaction. The majority
 (79.1%) of subjects were under 6 years old, of whom 46 were infected
 (63.9%). A total of 33 of the 91 subjects had one or more respiratory
 tract virus; there were 10 cases of triple infection and 5 of quadruple.
 Parainfluenza virus 4, respiratory syncytial virus B and enterovirus were
 the most common viruses in the clinical sample; present in 93.8% (15/16)
 of clinical subjects, and 6.7% (5/75) of community subjects (significant
 difference, p &lt; 0.001). Coronavirus OC43 was the most common virus
 detected in community members (13.3%, 10/75). A different strain,
 Coronavirus OC 229 E/NL63 was detected among subjects from the clinic
 (2/16) and not detected in the community. This pilot study provides
 evidence that data from the community can potentially represent different
 information than that sourced clinically, suggesting the need for
 community surveillance to enhance public health efforts and scientific
 understanding of respiratory infections.
