Data from: Anthropogenic extinction dominates Holocene declines of West Indian mammals

Siobhán B. Cooke, Liliana M. Dávalos, Alexis M. Mychajliw, Samuel T. Turvey & Nathan S. Upham
The extensive postglacial mammal losses in the West Indies provide an opportunity to evaluate extinction dynamics, but limited data have hindered our ability to test hypotheses. Here, we analyze the tempo and dynamics of extinction using a novel data set of faunal last-appearance dates and human first-appearance dates, demonstrating widespread overlap between humans and now-extinct native mammals. Humans arrived in four waves (Lithic, Archaic, Ceramic, and European), each associated with increased environmental impact. Large-bodied mammals...

Data from: Maternal food availability affects offspring performance and survival in a viviparous lizard

Yang Wang, Shu-Ran Li, Zhi-Gao Zeng, Liang Liang & Wei-Guo Du
1. Whether maternal effects are adaptive or not has been a long standing topic of discussion in evolutionary ecology. The effects of maternal diet on offspring has been addressed by several studies on diverse organisms, but results are typically conflicting or inconclusive. 2. In this study, we conducted food manipulation experiments with a factorial design (high and low maternal food conditions × high and low offspring food conditions) in a viviparous lacertid lizard (Eremias multiocellata)...

Data from: Demographic drivers of a refugee species: large-scale experiments guide strategies for reintroductions of hirola

Abdullahi H. Ali, Matthew J. Kauffman, Rajan Amin, Amos Kibara, Juliet King, David Mallon, Charles Musyoki & Jacob R. Goheen
Effective reintroduction strategies require accurate estimates of vital rates and the factors that influence them. We estimated vital rates of hirola (Beatragus hunteri) populations exposed to varying levels of predation and rangeland quality from 2012 to 2015, and then built population matrices to estimate the finite rate of population change (λ) and demographic sensitivities. Mean survival for all age classes and population growth was highest in the low predation/high-rangeland quality setting (λ = 1.08 ±...

Data from: Routine habitat switching alters the likelihood and persistence of infection with a pathogenic parasite

David R. Daversa, Andrea Manica, Jaime Bosch, Jolle W. Jolles & Trenton W. J. Garner
1.Animals switch habitats on a regular basis, and when habitats vary in suitability for parasitism, routine habitat switching alters the frequency of parasite exposure and may affect post-infection parasite proliferation. However, the effects of routine habitat switching on infection dynamics are not well understood. 2.We performed infection experiments, behavioural observations, and field surveillance to evaluate how routine habitat switching by adult alpine newts (Ichthyosaura alpestris) influences infection dynamics of the pathogenic parasite, Batrachochytrium dendrobatidis (Bd)....

Data from: Manipulating two olfactory cues causes a biological control beetle to shift to non-target plant species

Na Li, Jia-Ning Wei, Meredith C. Schuman, Shuang Li, Rui-Yan Ma & Jin Ge
Olfactory cues can determine the host preferences of herbivorous insects, but their role in host shifting is unclear. Host specificity and the potential for host shifts are important criteria for screening and post-release evaluation of biological control agents for invasive plants. However, the role of olfactory cues in mediating host shifts in biological control agents is not well understood. To investigate the role of olfactory cues in host selection of a reportedly monophagous flea beetle...

Sven Bacher, Tim M. Blackburn, Franz Essl, Piero Genovesi, Jaakko Heikkilä, Jonathan M. Jeschke, Glyn Jones, Reuben Keller, Marc Kenis, Christoph Kueffer, Angeliki F. Martinou, Wolfgang Nentwig, Jan Pergl, Petr Pyšek, Wolfgang Rabitsch, David M. Richardson, Helen E. Roy, Wolf-Christian Saul, Riccardo Scalera, Montserrat Vila, John R. U. Wilson, Sabina Kumschick & Sabrina Kumschick
Many alien taxa are known to cause socio-economic impacts by affecting the different constituents of human well-being (security; material and non-material assets; health; social, spiritual and cultural relations; freedom of choice and action). Attempts to quantify socio-economic impacts in monetary terms are unlikely to provide a useful basis for evaluating and comparing impacts of alien taxa because they are notoriously difficult to measure and important aspects of human well-being are ignored. Here, we propose a...

Data from: Mixing of porpoise ecotypes in southwestern UK waters revealed by genetic profiling

Michael C. Fontaine, Oliver Thatcher, Nicolas Ray, Sylvain Piry, Andrew Brownlow, Nicholas J. Davison, Paul Jepson, Rob Deaville & Simon J. Goodman
Contact zones between ecotypes are windows for understanding how species may react to climate changes. Here, we analysed the fine-scale genetic and morphological variation in harbour porpoises (Phocoena phocoena) around the UK by genotyping 591 stranded animals at nine microsatellite loci. The data were integrated with a prior study to map at high resolution the contact zone between two previously identified ecotypes meeting in the northern Bay of Biscay. Clustering and spatial analyses revealed that...

Data from: The evolution of post-pairing male mate choice

Nan Lyu, Maria R. Servedio, Huw Lloyd & Yue-Hua Sun
An increasing number of empirical studies in animals have demonstrated male mate choice. However, little is known about the evolution of post-pairing male choice, specifically that which occurs by differential allocation of male parental care in response to female signals. We use a population genetic model to examine whether such post-pairing male mate choice can evolve when males face a trade-off between parental care and extra-pair copulations (EPCs). Specifically, we assume that males allocate more...

Data from: Climate warming and humans played different roles in triggering Late Quaternary extinctions in east and west Eurasia

Xinru Wan & Zhibin Zhang
Climate change and humans are proposed as the two key drivers of total extinction of many large mammals in the Late Pleistocene and Early Holocene, but disentangling their relative roles remains challenging owing to a lack of quantitative evaluation of human impact and climate-driven distribution changes on the extinctions of these large mammals in a continuous temporal–spatial dimension. Here, our analyses showed that temperature change had significant effects on mammoth (genus Mammuthus), rhinoceros (Rhinocerotidae), horse...

Data from: Is embryonic hypothermia tolerance common in birds?

Jin-Ming Zhao, Zhi-Ming Han & Yue-Hua Sun
Avian incubation temperatures oscillate within narrow limits to ensure proper embryonic development. However, field observations and experimental studies have found that some species can tolerate very low incubation temperatures, either regularly or occasionally. We artificially incubated eggs from five domestic species, which represent a range of egg sizes, to examine whether a diversity of avian species could exhibit an unusual hypothermia tolerance, as observed in the field. We found that eggs of the chicken (Gallus...

Data from: Population transcriptomes reveal synergistic responses of DNA polymorphism and RNA expression to extreme environments on the Qinghai–Tibetan Plateau in a predatory bird

Shengkai Pan, Tongzuo Zhang, Zhengqin Rong, Li Hu, Zhongru Gu, Qi Wu, Shanshan Dong, Qiong Liu, Zhenzhen Lin, Lucia Deutschova, Xin-Hai Li, Andrew Dixon, Michael W. Bruford, Xiangjiang Zhan & Xinhai Li
Low oxygen and temperature pose key physiological challenges for endotherms living on the Qinghai–Tibetan Plateau (QTP). Molecular adaptations to high-altitude living have been detected in the genomes of Tibetans, their domesticated animals and a few wild species, but the contribution of transcriptional variation to altitudinal adaptation remains to be determined. Here we studied a top QTP predator, the saker falcon, and analysed how the transcriptome has become modified to cope with the stresses of hypoxia...

Data from: Cave Stedocys spitting spiders illuminate the history of the Himalayas and Southeast Asia

Yufa Luo & Shuqiang Li
Stedocys spitting spiders (Araneae: Scytodidae) inhabit subterranean environments and have poor dispersal abilities. The Cenozoic Indian–Eurasian collision affected the regional biota of this genus, which occurs in parts of Indochina. Phylogeographical pattern of Stedocys based on multigene DNA sequence datasets reveals how tectonic history drove four biological splits. The first split dates to the late Paleocene–Eocene and involves the Truong Son Mountain Range and Mekong River. The other splits associate with the Eocene–Oligocene transition, including...

Data from: Predicting animal behaviour using deep learning: GPS data alone accurately predict diving in seabirds

Ella Browning, Mark Bolton, Ellie Owen, Akiko Shoji, Tim Guilford & Robin Freeman
1.In order to prevent further global declines in biodiversity, identifying and understanding key habitats is crucial for successful conservation strategies. For example, globally, seabird populations are under threat and animal movement data can identify key at-sea areas and provide valuable information on the state of marine ecosystems. To date, in order to locate these areas, studies have used Global Positioning System (GPS) to record position and are sometimes combined with Time Depth Recorder (TDR) devices...

Data from: Pathogen richness and abundance predict patterns of adaptive MHC variation in insular amphibians

Supen Wang, Conghui Liu, Anthony B. Wilson, Na Zhao, Xianping Li, Wei Zhu, Xu Gao, Xuan Liu & Yiming Li
The identification of the factors responsible for genetic variation and differentiation at adaptive loci can provide important insights into the evolutionary process, and is crucial for the effective management of threatened species. We studied the impact of environmental viral richness and abundance on functional diversity and differentiation of the MHC class Ia locus in populations of the black-spotted pond frog (Pelophylax nigromaculatus), an IUCN-listed species, on 24 land-bridge islands of the Zhoushan Archipelago and 3...

Data from: Reliable effective number of breeders/adult census size ratios in seasonal-breeding species: opportunity for integrative demographic inferences based on capture-mark-recapture data and multilocus genotypes

Gregorio Sánchez-Montes, Jinliang Wang, Arturo H. Ariño, José Luis Vizmanos & Íñigo Martínez-Solano
The ratio of the effective number of breeders (Nb) to the adult census size (Na), Nb/ Na, approximates the departure from the standard capacity of a population to maintain genetic diversity in one reproductive season. This information is relevant for assessing population status, understanding evolutionary processes operating at local scales and unraveling how life-history traits affect these processes. However, our knowledge on Nb/Na ratios in nature is limited because estimation of both parameters is challenging....

Data from: Widespread gene flow between oceans in a pelagic seabird species complex

Claire Raisin, Deborah A. Dawson, Helen Hipperson, Gavin J. Horsburgh, Jim J. Groombridge, Stefanie M.H. Ismar, Paul Sweet, Carl G. Jones, Vikash Tatayah, Kevin Ruhomaun, Norris Ken, Katherine A. Booth Jones, Malcolm A.C. Nicoll, Malcolm A. C. Nicoll, Ken Norris & Stefanie M. H. Ismar
Global-scale gene flow is an important concern in conservation biology as it has the potential to either increase or decrease genetic diversity in species and populations. Although many studies focus on the gene flow between different populations of a single species, the potential for gene flow and introgression between species is understudied, particularly in seabirds. The only well-studied example of a mixed-species, hybridizing population of petrels exists on Round Island, in the Indian Ocean. Previous...

Data from: Hot dogs: high ambient temperatures impact reproductive success in a tropical carnivore

Rosie Woodroffe, Rosemary Groom & J. Weldon McNutt
Climate change imposes an urgent need to recognise and conserve the species likely to be worst affected. However, while ecologists have mostly explored indirect effects of rising ambient temperatures on temperate and polar species, physiologists have predicted direct impacts on tropical species. The African wild dog (Lycaon pictus), a tropical species, exhibits few of the traits typically used to predict climate change vulnerability. Nevertheless, we predicted that wild dog populations might be sensitive to weather...

Data from: Inbreeding and inbreeding avoidance in wild giant pandas

Yibo Hu, Yonggang Nie, Fuwen Wei, Tianxiao Ma, Russell Van Horn, Xiaoguang Zheng, Ronald Swaisgood, Zhixin Zhou, Wenliang Zhou, Li Yan & Zejun Zhang
Inbreeding can have negative consequences on population and individual fitness, which could be counteracted by inbreeding avoidance mechanisms. However, the inbreeding risk and inbreeding avoidance mechanisms in endangered species are less studied. The giant panda, a solitary and threatened species, lives in many small populations and suffers from habitat fragmentation, which may aggravate the risk of inbreeding. Here, we performed long-term observations of reproductive behaviour, sampling of mother-cub pairs and large-scale genetic analyses on wild...

Data from: Reef accessibility impairs the protection of sharks

Jean-Baptiste Juhel, Laurent Vigliola, David Mouillot, Michel Kulbicki, Tom B. Letessier, Jessica J. Meeuwig & Laurent Wantiez
1. Reef sharks are declining worldwide under ever increasing fishing pressure with potential consequences on ecosystem functioning. Marine protected areas (MPAs) are currently one of the management tools to counteract the pervasive impacts of fishing. However, MPAs in which reef sharks are abundant tend to be located in remote and underexploited areas preventing a fair assessment of management effectiveness beyond remoteness from human activities. 2. Here we determine the conditions under which MPAs can effectively...

Data from: Estimating genotyping errors from genotype and reconstructed pedigree data

Jinliang Wang
1. Genotyping errors are rules rather than exceptions in reality, and are found in virtually all but very small datasets. These errors, even when occurring at an extremely low rate, can derail many genetic analyses such as parentage/sibship assignments and linkage/association studies. 2. Nonetheless, few robust and accurate methods are available for estimating the rate of occurrence of genotyping errors and for identifying individual erroneous genotypes at a locus. Methods based on duplicate genotyping are...

Data from: Using data from related species to overcome spatial sampling bias and associated limitations in ecological niche modeling

Huijie Qiao, Andrew Townsend Peterson, Liqiang Ji & Junhua Hu
1. Ecological niche modeling (ENM) is used widely to aid in conservation planning and management, often focusing on rare species characterized by the biased observations associated with restricted geographic ranges, habitat specialization, small population size, and limited natural history information. Generating reliable ENMs for such species is a challenge, however, owing to issues that arise from spatial sampling bias, such as model inaccuracy and overfitting. Here, using virtual scenarios, we assess the utility of integrating...

Data from: Assessing the conservation value of secondary savanna for large mammals in the Brazilian Cerrado

Guilherme B. Ferreira, Jorge A. Ahumada, Marcelo J. R. Oliveira, Fernando F. De Pinho, Izabela M. Barata, Chris Carbone & Ben Collen
Debate about the conservation value of secondary habitats has tended to focus on tropical forests, increasingly recognizing the role of secondary forests for biodiversity conservation. However, there remains a lack of information about the conservation value of secondary savannas. Here, we conducted a camera trap survey to assess the effect of secondary vegetation on large mammals in a Brazilian Cerrado protected area, using a single-season occupancy framework to investigate the response of individual species (species-level...

Data from: Nutritional imbalance suppresses migratory phenotypes of the Mongolian locust (Oedaleus asiaticus)

Arianne J. Cease, Jon F. Harrison, Shuguang Hao, Danielle C. Niren, Guangming Zhang, Le Kang, James S. Elser & James J. Elser
For many species, migration evolves to allow organisms to access better resources. However, the proximate factors that trigger these developmental changes, and how and why these vary across species, remain poorly understood. One prominent hypothesis is that poor-quality food promotes development of migratory phenotypes and this has been clearly shown for some polyphenic insects. In other animals, particularly long-distance bird migrants, it is clear that high-quality food is required to prepare animals for a successful...

Data from: Female lizards choose warm, moist nests that improve embryonic survivorship and offspring fitness

Shu-Ran Li, Xin Hao, Yang Wang, Bao-Jun Sun, Jun-Huai Bi, Yong-Pu Zhang, Fredric J. Janzen & Wei-Guo Du
1. The fitness consequence of maternal nest-site choice has attracted increasing scientific attention, but field studies identifying the long-term effects of nest-site choice on offspring survival and reproductive success are still rare in vertebrates. 2. To investigate the consequences of nest-site choice in lizards, we quantified the thermal and hydric conditions of nest sites that were chosen by female toad-headed agama (Phrynocephalus przewalskii) in the desert steppe of northern China. We also determined the effect...

Data from: Effects of sampling close relatives on some elementary population genetics analyses

Jinliang Wang
Many molecular ecology analyses assume the genotyped individuals are sampled at random from a population and thus are representative of the population. Realistically, however, a sample may contain excessive close relatives (ECR) because, for example, localized juveniles are drawn from fecund species. Our knowledge is limited about how ECR affect the routinely conducted elementary genetics analyses, and how ECR are best dealt with to yield unbiased and accurate parameter estimates. This study quantifies the effects...
