Contributions of wild and provisioned foods to the diets of domestic cats that depredate wild animals

Martina Cecchetti, Sarah Crowley, Cecily Goodwin, Holly Cole, Jennifer McDonald, Stuart Bearhop & Robbie McDonald
Predation of wildlife by domestic cats Felis catus presents a threat to biodiversity conservation in some ecological contexts. The proportions of wild prey captured and eaten by domestic cats and thus the contributions of wild prey to cat diets are hard to quantify. This limits understanding of any impacts of cats may have on wild animal populations and confounds analyses of the effects of interventions aimed at reducing wildlife killing. We used stable isotope analyses...

Multi-year time shift study of bacteria and phage dynamics in the phyllosphere

Emily Dewald-Wang, Nicole Parr, Katie Tiley, Alina Lee & Britt Koskella
Coevolutionary dynamics shape diversity within and among populations but are difficult to study directly. Time shift experiments, where populations of species A from one point in time are experimentally challenged against populations of species B from past, contemporary, and/or future time points, and vice versa, are a particularly powerful tool to measure coevolution. This approach has been primarily applied to study host-parasite interactions and proven useful in directly measuring coevolutionary change and distinguishing among coevolutionary...

Genotyping by sequencing data of five legume tree species widespread in the rainforests of West and Central Africa

Rosalía Piñeiro, Olivier J Hardy, Carolina Tovar, Shyam Gopalakrishnan, Filipe Garrett Vieira & M. Thomas P. Gilbert
Although today the forest cover is continuous in Central Africa this may have not always been the case, as the scarce fossil record in this region suggests that arid conditions might have significantly reduced tree density during the Ice Ages. Our aim was to investigate whether the dry ice-age periods left a genetic signature on tree species that can be used to infer the date of the past fragmentation of the rainforest. We sequenced reduced...

Major population splits coincide with episodes of rapid climate change in a forest-dependent bird

Vera-Maria Warmuth, Malcolm Burgess, Marko Mägi, Toni Laaksonen, Andrea Manica, Andreas Nord, Craig Primmer, Glenn-Peter Sætre, Wolfgang Winkel & Hans Ellegren
Climate change influences population demography by altering patterns of gene flow and reproductive isolation. Direct mutation rates offer the possibility for accurate dating on the within-species level but are currently only available for a handful of vertebrate species. Here, we use the first directly estimated mutation rate in birds to study the evolutionary history of pied flycatchers (Ficedula hypoleuca). Using a combination of demographic inference and environmental niche modelling, we show that all major population...

Potential risk zone for anthropogenic mortality of carnivores in Gandaki province, Nepal

Binaya Adhikari, Kedar Baral, Shivish Bhandari, Michelle Szydlowski, Ripu Kunwar, Saroj Panthi, Bijaya Neupane & Raj Koirala
Anthropogenic pressures in human-dominated landscapes often contribute to wildlife mortality. Carnivores are especially vulnerable to human-induced mortality due to the perceived threat to livestock and humans. Despite having widespread conservation implications, carnivore mortality data has been largely underutilized within Nepal. This study utilized Maxent to identify high-risk areas and explore the contribution of habitat attributes associated with carnivore mortality using the casualty database within the Gandaki province of central Nepal. We categorized the risk to...

Data for: Marking through moults: An evaluation of visible implant elastomer to permanently mark individuals in a lower termite species

Rebecca Padget & Faye Thompson
1. Advances in individual marking methods have facilitated detailed studies of animal populations and behaviour as they allow tracking of individuals through time and space. Hemimetabolous insects, representing a wide range of commonly-used model organisms, present a unique challenge to individual marking as they are not only generally small-bodied, but also moult throughout development, meaning that traditional surface marks are not persistent. 2. Visible implant elastomer (VIE) offers a potential solution as small amounts of...

Dataset for Toponym Resolution in Nineteenth-Century English Newspapers

Mariona Coll Ardanuy, David Beavan, Kaspar Beelen, Kasra Hosseini, Jon Lawrence, Katherine McDonough, Federico Nanni, Daniel van Strien & Daniel Wilson
We present a new dataset for the task of toponym resolution in digitised historical newspapers in English. It consists of 343 annotated articles from newspapers based in four different locations in England (Manchester, Ashton-under-Lyne, Poole and Dorchester), published between 1780 and 1870. The articles have been manually annotated with mentions of places, which are linked---whenever possible---to their corresponding entry on Wikipedia. The dataset is published on the British Library shared research repository, and is especially...

Processed airborne radio-echo sounding data from the IMAFI survey covering the Institute and Moller ice streams and the Patriot Hills, West Antarctica (2010/2011)

Neil Ross, Robert Bingham, Fausto Ferraccioli, Tom Jordan, Anne Le Brocq, David Rippin & Martin Siegert
An airborne radar survey was flown over the Institute and Moller ice streams in the Weddell Sea sector of West Antarctica in the austral summer of 2010/11 as part of the Institute-Moller Antarctic Funding Initiative (IMAFI) project (grant reference number: NE/G013071/1). This project was a NERC Antarctic Funding Initiative (AFI) collaborative project between the British Antarctic Survey and the Universities of Edinburgh, York, Aberdeen and Exeter with the aim to test the hypothesis that the...

Sex differences in behavioural and anatomical estimates of visual acuity in the green swordtail Xiphophorus helleri

Eleanor M Caves, Fanny De Busserolles & Laura A Kelley
Among fishes in the family Poeciliidae, signals such as colour patterns, ornaments, and courtship displays play important roles in mate choice and male-male competition. Despite this, visual capabilities in Poeciliids are understudied, in particular visual acuity, the ability to resolve detail. We used three methods to quantify visual acuity in male and female green swordtails (Xiphophorus helleri), a species in which body size and the length of the male's extended caudal fin ('sword') serve as...

Intralocus sexual conflict over optimal nutrient intake and the evolution of sex differences in lifespan and reproduction

John Hunt, Michael Hawkes, Sarah Lane, James Rapkin, Kim Jensen, Clarissa House & Scott Sakaluk
Despite widespread variation in lifespan across species, three clear patterns exist: sex differences in lifespan are ubiquitous, lifespan is commonly traded against reproduction, and nutrition has a major influence on these traits and how they trade-off. One process that potentially unites these patterns is Intralocus Sexual Conflict (IASC) over the optimal intake of nutrients for lifespan and reproduction. If nutrient intake has sex-specific effects on lifespan and reproduction and nutrient choice is genetically linked across...

The influence of biogeographical and evolutionary histories on morphological trait-matching and resource specialization in mutualistic hummingbird-plant networks

Bo Dalsgaard, Pietro Maruyama, Jesper Sonne, Katrine Hansen, Thais Zanata, Stefan Abrahamczyk, Ruben Alarcon, Andréa Araujo, Francielle Araújo, Silvana Buzato, Edgar Chávez-González, Aline Coelho, Pete Cotton, Román Díaz-Valenzuela, Maria Dufke, Paula Enríquez, Manoel Martins Dias Filho, Erich Fischer, Glauco Kohler, Carlos Lara, Flor Maria Las-Casas, Liliana Rosero Lasprilla, Adriana Machado, Caio Machado, Maria Maglianesi … & Ana M. Martín González
Functional traits can determine pairwise species interactions, such as those between plants and pollinators. However, the effects of biogeography and evolutionary history on trait-matching and trait-mediated resource specialization remain poorly understood. We compiled a database of 93 mutualistic hummingbird-plant networks (including 181 hummingbird and 1,256 plant species), complemented by morphological measures of hummingbird bill and floral corolla length. We divided the hummingbirds into their principal clades and used knowledge on hummingbird biogeography to divide the...

Data from: Telomere length is highly heritable and independent of growth rate manipulated by temperature in field crickets

Jelle Boonekamp, Rolando Rodríguez-Muñoz, Paul Hopwood, Erica Zuidersma, Ellis Mulder, Alastair Wilson, Simon Verhulst & Tom Tregenza
Many organisms are capable of growing faster than they do. Restrained growth rate has functionally been explained by negative effects on lifespan of accelerated growth. However, the underlying mechanisms remain elusive. Telomere attrition has been proposed as a causal agent and has been mostly studied in endothermic vertebrates. We established that telomeres exist as chromosomal-ends in a model insect, the field cricket G. campestris, using terminal restriction fragment and Bal 31 methods. Telomeres comprised TTAGGn...

Harnessing Artificial Intelligence technology and social media data to support Cultural Ecosystem Service assessments

Lukas Egarter Vigl, Thomas Marsoner, Valentina Giombini, Caroline Pecher, Heidi Simion, Egon Stemle, Erich Tasser & Daniel Depellegrin
Cultural Ecosystem Services (CES), such as aesthetic and recreational enjoyment, as well as sense of place and cultural heritage, play an outstanding role in the contribution of landscapes to human well-being. Scientists, however, still often struggle to understand how landscape characteristics contribute to deliver these intangible benefits, largely because it is hard to navigate how people value nature, and because there is a lack in methods that accommodate both comprehensive and time-efficient evaluations. Recent advances...

Data from: Longitudinal evidence that older parents produce offspring with longer telomeres in a wild social bird

Antony Brown, Emma Wood, Pablo Capilla-Lasheras, Xavier Harrison & Andrew Young
As telomere length (TL) often predicts survival and lifespan, there is considerable interest in the origins of inter-individual variation in TL. Cross-generational effects of parental age on offspring TL are thought to be a key source of variation, but the rarity of longitudinal studies that examine the telomeres of successive offspring born throughout the lives of parents leaves such effects poorly understood. Here, we exploit TL measures of successive offspring produced throughout the long breeding...

Post-epizootic microbiome associations across communities of neotropical amphibians

Phillip Jervis, Pol Pintanel, Kevin Hopkins, Claudia Wierzbicki, Jennifer Shelton, Emily Skelly, Goncalo Rosa, Diego Almeida-Reinoso, Maria Eugenia-Ordonez, Santiago Ron, Xavier Harrison, Andres Merino-Viteri & Matthew Fisher
Microbiome-pathogen interactions are increasingly recognised as an important element of host immunity. While these host-level interactions will have consequences for community disease dynamics, the factors which influence host microbiomes at larger scales are poorly understood. We here describe landscape scale pathogen-microbiome associations within the context of post-epizootic amphibian chytridiomycosis, a disease caused by the panzootic chytrid fungus Batrachochytrium dendrobatidis. We undertook a survey of Neotropical amphibians across altitudinal gradients in Ecuador ~30 years following the...

Chill coma recovery times and growth rates of early instar nymphs from populations of crickets (Gryllus campestris) from Northern Spain

Tom Tregenza
Understanding how species can thrive in a range of environments is a central challenge for evolutionary ecology. There is strong evidence for local adaptation along large-scale ecological clines in insects. However, potential adaptation among neighbouring populations differing in their environment has been studied much less. We used RAD-sequencing to quantify genetic divergence and clustering of ten populations of the field cricket Gryllus campestris in the Cantabrian Mountains of northern Spain, and an outgroup on the...

Ocean-scale footprint of a highly mobile fishing fleet: social-ecological drivers of fleet behaviour and evidence of illegal fishing

Claire Collins, Ana Nuno, Aloka Benaragama, Annette Broderick, Isuru Wijesundara, Dilhara Wijetunge & Tom Letessier
Managing the footprint of highly mobile fishing fleets is increasingly important due to continuing declines of fish populations. However, social-ecological drivers for fisher behaviour remain poorly understood for many fleets globally. Using the Sri Lankan fleet as a case study, we explored the role of social, environmental and policy drivers of effort distribution and illegal fishing. We used semi-structured interviews and participatory mapping with 95 fishers, combined with explanatory modelling (Generalised Linear Models, GLM) and...

Altruistic bet-hedging and the evolution of cooperation in a Kalahari bird

Pablo Capilla-Lasheras, Xavier Harrison, Emma Wood, Alastair Wilson & Andrew Young
Analyses of the global biogeography of altruism suggest that unpredictable environments have favoured the evolution of altruistic helping behaviour (helping to rear the offspring of others). It has therefore been hypothesised that selection for altruism may frequently arise because helping reduces variance in the reproductive success of relatives in unpredictable environments (a scenario termed ‘altruistic bet-hedging’). Here we show that helping behaviour does reduce environmentally-induced variance in the reproductive success of relatives in a wild...

Phage gene expression and host responses lead to infection-dependent costs of CRISPR immunity

Sean Meaden
CRISPR-Cas immune systems are widespread in bacteria and archaea, but not ubiquitous. Previous work has demonstrated that CRISPR immunity is associated with an infection-induced fitness cost, which may help explain the patchy distribution observed. However, the mechanistic basis of this cost has remained unclear. Using Pseudomonas aeruginosa PA14 and its phage DMS3vir as a model, we perform a 30-day evolution experiment under phage mediated selection. We demonstrate that although CRISPR is initially selected for, bacteria...

Resource quality determines the evolution of resistance and its genetic basis

Katherine Roberts, Sean Meaden, Stephen Sharpe, Toby Doyle, Suzanne Kay, Lewis Bartlett, Steve Paterson & Mike Boots
Parasites impose strong selection on their hosts, but the level of any evolved resistance may be constrained by the availability of resources. However, studies identifying the genomic basis of such resource-mediated selection are rare, particularly in non-model organisms. Here, we investigated the role of nutrition in the evolution of resistance to a DNA virus (PiGV), and any associated trade-offs in a lepidopteran pest species (Plodia interpunctella). Through selection experiments and whole genome re-sequencing we identify...
