Data from: A morphometric analysis of vegetation patterns in dryland ecosystems

Luke Mander, Stefan C. Dekker, Mao Li, Washington Mio, Surangi W. Punyasena & Timothy M. Lenton
Vegetation in dryland ecosystems often forms remarkable spatial patterns. These range from regular bands of vegetation alternating with bare ground, to vegetated spots and labyrinths, to regular gaps of bare ground within an otherwise continuous expanse of vegetation. It has been suggested that spotted vegetation patterns could indicate that collapse into a bare ground state is imminent, and the morphology of spatial vegetation patterns, therefore, represents a potentially valuable source of information on the proximity...

Data from: Experimental priming of independent and interdependent activity does not affect culturally-variable psychological processes

Kesson Magid, Vera Sarkol & Alex Mesoudi
Cultural psychologists have shown that people from Western countries exhibit more independent self-construal and analytic (rule-based) cognition than people from East Asia, who exhibit more interdependent self-construal and holistic (relationship-based) cognition. One explanation for this cross-cultural variation is the ecocultural hypothesis, which links contemporary psychological differences to ancestral differences in subsistence and societal cohesion: Western thinking formed in response to solitary herding, which fostered independence, while East Asian thinking emerged in response to communal rice...

Data from: Evolvability meets biogeography: evolutionary potential decreases at high and low environmental favourability

Jesús Martinez-Padilla, Alba Estrada, Regan Early & Francisco García-González
Understanding and forecasting the effects of environmental change on wild populations requires knowledge on a critical question: do populations have the ability to evolve in response to that change? However, our knowledge on how evolution works in wild conditions under different environmental circumstances is extremely limited. We investigated how environmental variation influences the evolutionary potential of phenotypic traits. We used published data to collect or calculate 135 estimates of evolvability of morphological traits of European...

Data from: Bayesian inference reveals positive but subtle effects of experimental fishery closures on marine predator demographics

Richard B. Sherley, Barbara J. Barham, Peter J. Barham, Kate J. Campbell, Robert J.M. Crawford, Jennifer Grigg, Catharine Horswill, Alistair McInnes, Taryn L. Morris, Lorien Pichegru, Antje Steinfurth, Florian Weller, Henning Winker, Stephen C. Votier & Cat Horswill
Global forage-fish landings are increasing, with potentially grave consequences for marine ecosystems. Predators of forage fish may be influenced by this harvest, but the nature of these effects is contentious. Experimental fishery manipulations offer the best solution to quantify population-level impacts, but are rare. We used Bayesian inference to examine changes in chick survival, body condition and population growth rate of endangered African penguins Spheniscus demersus in response to eight years of alternating time-area closures...

Data from: Effects of macronutrient intake on the lifespan and fecundity of the marula fruit fly, Ceratitis cosyra (Tephritidae): extreme lifespan in a host specialist.

Kevin Malod, C. Ruth Archer, John Hunt, Susan W. Nicolson & Christopher W. Weldon
In insects, lifespan and reproduction are strongly associated with nutrition. The ratio and amount of nutrients individuals consume affects their life expectancy and reproductive investment. The geometric framework (GF) enables us to explore how animals regulate their intake of multiple nutrients simultaneously and determine how these nutrients interact to affect life history traits of interest. Studies using the GF on host-generalist tephritid flies have highlighted trade-offs between longevity and reproductive effort in females, mediated by...

Data from: Contrasting patterns of population structure and gene flow facilitate exploration of connectivity in two widely distributed temperate octocorals

Lyndsey P. Holland, Tom L. Jenkins & Jamie R. Stevens
Connectivity is an important component of metapopulation dynamics in marine systems and can influence population persistence, migration rates and conservation decisions associated with Marine Protected Areas (MPAs). In this study, we compared the genetic diversity, gene flow and population structure of two octocoral species, Eunicella verrucosa and Alcyonium digitatum, in the northeast Atlantic (ranging from the northwest of Ireland and the southern North Sea, to southern Portugal), using two panels of 13 and 8 microsatellite...

Data from: Pregnancy is detected via odour in a wild cooperative breeder

Jessica Mitchell, Michael A. Cant & Hazel J. Nichols
Among mammals, scent has long been known to encode oestrus; however, in many species, detecting pregnancy may also be important in terms of both competition and mate-choice. Here, we show, through odour presentation experiments, that pregnancy is discernible via scent by both sexes in the cooperatively breeding banded mongoose, Mungos mungo. Males spent more time investigating and were more likely to scent mark the odours of non-pregnant females, compared to pregnant females. Females showed increased...

Data from: Artificial light at night alters trophic interactions of intertidal invertebrates

Charlotte N. Underwood, Thomas W. Davies & Ana M. Queirós
Despite being globally widespread in coastal regions, the impacts of light pollution on intertidal ecosystems has received little attention. Intertidal species exhibit many night-time-dependent ecological strategies, including feeding, reproduction, orientation and predator avoidance, which are likely negatively affected by shifting light regimes, as has been observed in terrestrial and aquatic taxa. Coastal lighting may shape intertidal communities through its influence on the nocturnal foraging activity of dogwhelks (Nucella lapillus), a widespread predatory mollusc that structures...

Data from: SIDER: an R package for predicting trophic discrimination factors of consumers based on their ecology and phylogenetic relatedness

Kevin Healy, Thomas Guillerme, Seán B. A. Kelly, Richard Inger, Stuart Bearhop & Andrew L. Jackson
Stable isotope mixing models (SIMMs) are an important tool used to study species’ trophic ecology. These models are dependent on, and sensitive to, the choice of trophic discrimination factors (TDF) representing the offset in stable isotope delta values between a consumer and their food source when they are at equilibrium. Ideally, controlled feeding trials should be conducted to determine the appropriate TDF for each consumer, tissue type, food source, and isotope combination used in a...

Data from: Seasonal variation in daily patterns of social contacts in the European badger Meles meles

Matthew J. Silk, Nicola Weber, Lucy C. Steward, Richard J. Delahay, Darren P. Croft, David J. Hodgson, Mike Boots & Robbie A. McDonald
Social interactions among hosts influence the persistence and spread of infectious pathogens. Daily and seasonal variation in the frequency and type of social interactions will play an important role in disease epidemiology and, alongside other factors, may have an influence on wider disease dynamics by causing seasonal forcing of infection, especially if the seasonal variation experienced by a population is considerable. We explored temporal variation in within-group contacts in a high-density population of European badgers...

Data from: Fluctuating seawater pH/ p CO 2 regimes are more energetically expensive than static pH/ p CO 2 levels in the mussel Mytilus edulis

Stephanie Mangan, Mauricio A. Urbina, Helen S. Findlay, Rod W. Wilson & Ceri Lewis
Ocean acidification (OA) studies typically use stable open-ocean pH or CO2 values. However, species living within dynamic coastal environments can naturally experience wide fluctuations in abiotic factors, suggesting their responses to stable pH conditions may not be reflective of either present or near-future conditions. Here we investigate the physiological responses of the mussel Mytilus edulis to variable seawater pH conditions over short- (6 h) and medium-term (2 weeks) exposures under both current and near-future OA...

Data from: Evaluating anthropogenic threats to endangered killer whales to inform effective recovery plans

Robert C. Lacy, Rob Williams, Erin Ashe, , Lauren J. N. Brent, Christopher W. Clark, Darren P. Croft, Deborah A. Giles, Misty MacDuffee & Paul C. Paquet
Understanding cumulative effects of multiple threats is key to guiding effective management to conserve endangered species. The critically endangered, Southern Resident killer whale population of the northeastern Pacific Ocean provides a data-rich case to explore anthropogenic threats on population viability. Primary threats include: limitation of preferred prey, Chinook salmon; anthropogenic noise and disturbance, which reduce foraging efficiency; and high levels of stored contaminants, including PCBs. We constructed a population viability analysis to explore possible demographic...

Data from: Wild birds respond to flockmate loss by increasing their social network associations to others

Josh A. Firth, Bernhard Voelkl, Ross A. Crates, Lucy M. Aplin, Dora Biro, Darren P. Croft & Ben C. Sheldon
Understanding the consequences of losing individuals from wild populations is a current and pressing issue, yet how such loss influences the social behaviour of the remaining animals is largely unexplored. Through combining the automated tracking of winter flocks of over 500 wild great tits (Parus major) with removal experiments, we assessed how individuals' social network positions responded to the loss of their social associates. We found that the extent of flockmate loss that individuals experienced...

Data from: Demonstrating multiple benefits from periodically harvested fisheries closures

Jordan S. Goetze, Joachim Claudet, Fraser Januchowski-Hartley, Timothy J. Langlois, Shaun K. Wilson, Crow White, Rebecca Weeks & Stacy D. Jupiter
1.Periodically harvested closures (PHCs) are one of the most common forms of fisheries management in Melanesia, demonstrating multiple objectives, including sustaining fish stocks and increasing catch efficiency to support small-scale fisheries. No studies have comprehensively assessed their ability to provide short-term fisheries benefits across the entire harvest regime. 2.We present a novel analytical framework to guide a meta-analysis and assist future research in conceptualizing and assessing the potential of PHCs to deliver benefits for multiple...

Data from: Individual quality and age but not environmental or social conditions modulate costs of reproduction in a capital breeder

Lucie Debeffe, Jocelyn Poissant & Philip D. McLoughlin
Costs associated with reproduction are widely known to play a role in the evolution of reproductive tactics with consequences to population and eco-evolutionary dynamics. Evaluating these costs as they pertain to species in the wild remains an important goal of evolutionary ecology. Individual heterogeneity, including differences in individual quality (i.e., among-individual differences in traits associated with survival and reproduction) or state, and variation in environmental and social conditions can modulate the costs of reproduction; however,...

Data from: In situ measurements of animal morphological features; a non-invasive method

Mylswamy Mahendiran, Mylswamy Parthiban, Parappurath Abdul Azeez, Rajaratinavelu Nagarajan & Rajarathinavelu Nagarajan
1) Measurements of morphological features are important for ecological studies, especially on free-ranging wild animal species. Conventionally, specimens either dead or in captivity are used for morphometric studies, which is difficult in the case of wild species for several reasons. Capturing would be even futile when research questions are relating to issues such as prey size selection or estimation of intake rate in under field conditions, where in situ morphometric measurements are inevitable. Remotely estimating...

Data from: Early social experience shapes female mate choice in guppies

Alessandro Macario, Darren P. Croft, John A. Endler & Safi K. Darden
Mating decisions are often plastic and individuals adjust their decisions depending on the social and ecological environment. Although the implications of the social environment on mate choice has been well studied in species with parental care, surprisingly little research has examined the role played by the social environment experienced during ontogeny in species lacking parental care. We used guppies to test the hypothesis that females alter their mate choice in response to variation in the...

Data from: A phylogenetically controlled meta-analysis of biologging device effects on birds: deleterious effects and a call for more standardized reporting of study data

Thomas W. Bodey, Ian R. Cleasby, Fraser Bell, Nicole Parr, Anthony Schultz, Stephen C. Votier & Stuart Bearhop
1.The use of biologging devices continues to increase, with technological advances yielding remarkable ecological insights and generating new research questions. However, as devices develop and are deployed more widely, there is a need to update our knowledge of the potential ethical impacts to allow scientists to balance these against the knowledge gained. 2.We employed a suite of phylogenetically controlled meta-analyses on a dataset comprising more than 450 published effect sizes across 214 different studies to...

Data from: Empirical and theoretical investigation into the potential impacts of insecticide resistance on the effectiveness of insecticide-treated bed nets

Katey D. Glunt, Maureen Coetzee, Silvie Huijben, A. Alphonsine Koffi, Penelope A. Lynch, Raphael N'Guessan, Welbeck A. Oumbouke, Eleanore D. Sternberg & Matthew B. Thomas
In spite of widespread insecticide resistance in vector mosquitoes throughout Africa, there is limited evidence that long lasting insecticidal bed nets (LLINs) are failing to protect against malaria. Here, we showed that LLIN contact in the course of host-seeking resulted in higher mortality of resistant Anopheles spp. mosquitoes than predicted from standard laboratory exposures with the same net. We also found that sub-lethal contact with an LLIN caused a reduction in blood feeding and subsequent...

Data from: The diversity of floral temperature patterns, and their use by pollinators

Michael J. M. Harrap, Sean A. Rands, Natalie Hempel De Ibarra, Heather M. Whitney & Michael JM Harrap
Pollinating insects utilise various sensory cues to identify and learn rewarding flower species. One such cue is floral temperature, created by captured sunlight or plant thermogenesis. Bumblebees, honeybees and stingless bees can distinguish flowers based on differences in overall temperature between flowers. We report here that floral temperature often differs between different parts of the flower creating a temperature structure or pattern. Temperature patterns are common, with 55% of 118 plant species thermographed, showing within-flower...

Data from: Effects of age and reproductive status on individual foraging site fidelity in a long-lived marine predator

Stephen C. Votier, Annette L. Fayet, Stuart Bearhop, Thomas W. Bodey, Bethany L. Clark, James Grecian, Tim Guilford, Keith C. Hamer, Jana W.E. Jeglinski, Greg Morgan, Ewan Wakefield, Samantha C. Patrick & Jana W. E. Jeglinski
Individual foraging specializations, where individuals use a small component of the population niche width, are widespread in nature with important ecological and evolutionary implications. In long-lived animals, foraging ability develops with age, but we know little about the ontogeny of individuality in foraging. Here we use precision global positioning system (GPS) loggers to examine how individual foraging site fidelity (IFSF), a common component of foraging specialization, varies between breeders, failed breeders and immatures in a...

Data from: Family network size and survival across the lifespan of female macaques

Lauren J. N. Brent, Angelina Ruiz Lambides & Michael L. Platt
Two decades of research suggest social relationships have a common evolutionary basis in humans and other gregarious mammals. Critical to the support of this idea is growing evidence that mortality is influenced by social integration, but when these effects emerge and how long they last is mostly unknown. Here, we report in adult female macaques that the impact of number of close adult female relatives, a proxy for social integration, on survival is not experienced...

Data from: Evolutionary divergence in life history traits among populations of the Lake Malawi cichlid fish Astatotilapia calliptera

Paul J. Parsons, Jon R. Bridle, Lukas Rüber & Martin J. Genner
During the early stages of adaptive radiation, populations diverge in life history traits such as egg size and growth rates, in addition to eco-morphological and behavioral characteristics. However, there are few studies of life history divergence within ongoing adaptive radiations. Here, we studied Astatotilapia calliptera, a maternal mouthbrooding cichlid fish within the Lake Malawi haplochromine radiation. This species occupies a rich diversity of habitats, including the main body of Lake Malawi, as well as peripheral...

Data from: Multichannel feeding by spider functional groups is driven by feeding strategies and resource availability

Matthew J. Perkins, Richard Inger, Stuart Bearhop & Dirk Sanders
Multichannel feeding, whereby consumers feed across resource channels such as upon herbivore and detritivore resources, acts to link discrete compartments of a food web with implications for ecosystem functioning and stability. Currently however, we have little understanding which feeding strategies of consumers underlie multichannel feeding. We therefore link spider functional group and resource density-dependent or density-independent feeding strategies to multichannel feeding by quantifying not only consumer diet, but also the relative availability of resources. Here...

Data from: Carotenoid coloration is related to fat digestion efficiency in a wild bird

Christina Madonia, Pierce Hutton, Mathieu Giraudeau & Tuul Sepp
Some of the most spectacular visual signals found in the animal kingdom are based on dietarily derived carotenoid pigments (which cannot be produced de novo), with a general assumption that carotenoids are limited resources for wild organisms, causing trade-offs in allocation of carotenoids to different physiological functions and ornamentation. This resource trade-off view has been recently questioned, since the efficiency of carotenoid processing may relax the trade-off between allocation toward condition or ornamentation. This hypothesis...
