Decline and Fall: the causes of group failure in cooperatively breeding meerkats

Christopher Duncan, Marta Manser & Tim Clutton-Brock
In many social vertebrates, variation in group persistence exerts an important effect on individual fitness and population demography. However, few studies have been able to investigate the failure of groups or the causes of the variation in their longevity. We use data from a long-term study of cooperatively breeding meerkats, Suricata suricatta, to investigate the different causes of group failure and the factors that drive these processes. Many newly formed groups failed within a year...

Supplemental material: Astrocyte biomarkers in Alzheimer’s disease: a systematic review and meta-analysis

Objective: To perform a systematic review and meta-analysis to determine whether fluid and imaging astrocyte biomarkers are altered in Alzheimer's disease (AD). Methods: PubMed and Web of Science databases were searched for articles reporting fluid or imaging astrocyte biomarkers in AD. Pooled effect sizes were determined with mean differences (SMD) using the Hedge’s G method with random-effects to determine biomarker performance. Adapted questions from QUADAS-2 were applied for quality assessment. A protocol for this study...

Spatial dynamics of pathogen transmission in communally roosting species: Impacts of changing habitats on bat-virus dynamics

Tamika Lunn, Tamika Lunn, Alison Peel, Hamish McCallum, Peggy Eby, Maureen Kessler, Raina Plowright & Olivier Restif
1. The spatial organisation of populations determines their pathogen dynamics. This is particularly important for communally roosting species, whose aggregations are often driven by the spatial structure of their environment. 2. We develop a spatially explicit model for virus transmission within roosts of Australian tree-dwelling bats (Pteropus spp.), parameterised to reflect Hendra virus. The spatial structure of roosts mirrors three study sites, and viral transmission between groups of bats in trees was modelled as a...

Data for: Larval environmental conditions influence plasticity in resource use by adults in the burying beetle, Nicrophorus vespilloides

Matthew Schrader, Benjamin Jarrett & Rebecca Kilner
Recent studies have shown that intraspecific patterns of phenotypic plasticity can mirror patterns of evolutionary diversification among species. This appears to be the case in Nicrophorus beetles. Within species, body size is positively correlated with the size of carrion used to provision larvae and parental performance. Likewise, among species, variation in body size influences whether species exploit smaller or larger carrion and the extent to which larvae depend on parental care. However, it is unclear...

Evidence shortfalls in the recommendations and guidance underpinning ecological mitigation for infrastructure developments

Sara Bronwen Hunter, Sophus Zu Ermgassen, Harriet Downey, Richard Griffiths & Caroline Howe
1. In the UK and European Union, legal protection of species from the impacts of infrastructure development depends upon a number of ecological mitigation and compensation (EMC) measures to moderate the conflict between development and conservation. However, the scientific evidence supporting their effectiveness has not yet been comprehensively assessed. 2. This study compiled the measures used in practice, identified and explored the guidance that informed them and, using the Conservation Evidence database, evaluated the empirical...

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...

Data: Direct and indirect effects of high temperatures on fledging in a cooperatively breeding bird

Amanda Bourne, Amanda Ridley, Claire Spottiswoode & Susan Cunningham
High temperatures and low rainfall consistently constrain reproduction in arid-zone bird species. Understanding the mechanisms underlying this pattern is critical for predicting how climate change will influence population persistence and to inform conservation and management. In this study, we analysed Southern Pied Babbler Turdoides bicolor nestling survival, daily growth rate and adult investment behaviour during the nestling period over three austral summer breeding seasons. High temperatures were associated with lower body mass, shorter tarsi, and...

Data from: Contextual inference underlies the learning of sensorimotor repertoires

James Heald, Daniel Wolpert & Máté Lengyel
Humans spend a lifetime learning, storing and refining a repertoire of motor memories. For example, through experience, we become proficient at manipulating a large range of objects with distinct dynamical properties. However, it is unknown what principle underlies how our continuous stream of sensorimotor experience is segmented into separate memories and how we adapt and use this growing repertoire. Here we develop a theory of motor learning based on the key principle that memory creation,...

Cognition and covariance in the producer-scrounger game

Michael Reichert, Julie Morand-Ferron, Ipek Kulahci, Josh Firth, Gabrielle Davidson, Sam Crofts & John Quinn
1. The producer-scrounger game is a key element of foraging ecology in many systems. Producing and scrounging typically covary negatively, but partitioning this covariance into contributions of individual plasticity and consistent between individual differences is key to understanding population level consequences of foraging strategies. Furthermore, little is known about the role cognition plays in the producer-scrounger game. 2. We investigated the role of cognition in these alternative foraging tactics in wild mixed-species flocks of great...

Populations of high-value predators reflect the traits of their prey dataset

Cayetano Gutierrez Canovas, Thomas Worthington, David Noble, Daniel Perkins, Ian Vaughan, Guy Woodward, Steve Ormerod & Isabelle Durance
The extent to which prey traits combine to influence the abundance of predators is still poorly understood, particularly for mixed predators in sympatry and in aquatic ecosystems. In this study, we characterise prey use and distribution in iconic bird (grey wagtails and Eurasian dippers) and fish species (brown trout and Atlantic salmon) to assess whether prey traits could predict populations of these four riverine predators. Specifically, we hypothesised that: (i) Prey key traits would predict...

Integrating stakeholders’ perspectives and spatial modelling to develop scenarios of future land use and land cover change in northern Tanzania

Rebecca Kariuki, Linus Munishi, Colin Courtney-Mustaphi, Claudia Capitani, Anna Shoemaker, Paul Lane & Rob Marchant
Rapid rates of land use and land cover change (LULCC) in eastern Africa and limited instances of genuinely equal partnerships involving scientists, communities and decision makers challenge the development of robust pathways toward future environmental and socioeconomic sustainability. We use a participatory modelling tool, Kesho, to assess the biophysical, socioeconomic, cultural and governance factors that influenced past (1959-1999) and present (2000-2018) LULCC in northern Tanzania and to simulate four scenarios of land cover change to...

Towards genetic modification of plant-parasitic nematodes: Delivery of macromolecules to male germlines and expression of exogenous mRNA in second stage juveniles

Sebastian Eves-Van Den Akker, Olaf Kranse & Helen Beasley
Plant-parasitic nematodes are a current and future threat to food security, causing an estimated 100 billion USD in crop losses each year. The most problematic are the obligate sedentary endoparasites (primarily root knot nematodes and cyst nematodes). Progress in understanding their biology is held back by a lack of tools for functional genetics. Forward genetics is largely restricted to studies of natural variation in populations, and reverse genetics is entirely reliant on RNA interference. There...

Fish avoid visually noisy environments where prey targeting is reduced

Joanna Attwell, Christos Ioannou, Chris Reid & James Herbert-Read
The environment contains different forms of ecological no­­­ise that can reduce the ability of animals to detect information. Here we ask whether animals adapt their behaviour to either exploit or avoid areas of their environment with increased dynamic visual noise. Three-spined sticklebacks (Gasterosteus aculeatus) were immersed into environments with a simulated form of naturally occurring visual noise – moving light bands that form on underwater substrates caused by the refraction of light through surface waves....

Cortex cis-regulatory switches establish scale colour identity and pattern diversity in Heliconius

Luca Livraghi, Joseph J. Hanly, Ling Sheng Loh, Anna Ren, Ian A. Warren, Carolina Concha, Charlotte Wright, Jonah M. Walker, Jessica Foley, Henry Arenas-Castro, Arnaud Martin, William O. McMillan, Chris D. Jiggins, Steven M. Van Bellghem, Gabriela Montejo-Kovacevich, James J. Lewis, Micheal W. Perry, Zachary H. Goldberg, Laura H. Lopez, Riccardo Papa & Eva S.M. Van Der Heijden
In Heliconius butterflies, wing pattern diversity is controlled by a few genes of large effect that regulate colour pattern switches between morphs and species across a large mimetic radiation. One of these genes, cortex, has been repeatedly associated with colour pattern evolution in butterflies. Here we carried out CRISPR knock-outs in multiple Heliconius species and show that cortex is a major determinant of scale cell identity. Chromatin accessibility profiling and introgression scans identified cis-regulatory regions...

Non-alcoholic fatty liver disease animal models database

Jake Mann
Selecting and designing an optimal animal model is a key component of translational science, though there is often no consensus on which model is optimal for a particular disease. Here, we generated a database of 3920 rodent models of non-alcoholic fatty liver disease (NAFLD). Due to high heterogeneity in design, few models had been cited more than once. Analysis of genetic models provided evidence for the role of adipose dysfunction and perturbation of the innate...

Prior to consensus, panelists...

Data from: A molecular phylogeny of forktail damselflies (genus Ischnura) reveals a dynamic macroevolutionary history of female colour polymorphisms

Rachel Blow, Beatriz Willink & Erik Svensson
Colour polymorphisms are popular study systems among biologists interested in evolutionary dynamics, genomics, sexual selection and sexual conflict. In many damselflies, such as in the globally distributed genus Ischnura (forktails), female colour polymorphisms occur in some species. Female-polymorphic species contain two or three female morphs, one of which is male-coloured (androchrome or male mimic) and co-exists with sexually dimorphic (heterochrome) females. These female colour polymorphisms are considered to be maintained by frequency-dependent sexual conflict, but...
