Data from: Intercolony movement of pre-breeding seabirds over oceanic scales: implications of cryptic age-classes for conservation and metapopulation dynamics

Anthony W. J. Bicknell, Mairi E. Knight, David T. Bilton, Maria Campbell, James B. Reid, Jason Newton & Stephen C. Votier
Aim: Demographic linkage between subpopulations plays a critical role in population processes. Metapopulation dynamics, however, remains one of the most poorly understood aspects of population biology. This is especially true for small, pelagic seabirds because their discrete subpopulations are located on offshore islands, separated by vast areas of open ocean, making monitoring logistically challenging. Seabird populations often contain large numbers of immature pre-breeders that may be important for subpopulation connectivity and demography, but are poorly...

Data from: Functional traits explain variation in plant life history strategies

Peter B. Adler, Roberto Salguero-Gómez, Aldo Compagnoni, Joanna S. Hsu, Jayanti Ray-Mukherjee, Cyril Mbeau-Ache & Miguel Franco
Ecologists seek general explanations for the dramatic variation in species abundances in space and time. An increasingly popular solution is to predict species distributions, dynamics and responses to environmental change based on easily measured anatomical and morphological traits. Trait-based approaches assume that simple functional traits influence fitness and life history evolution, but rigorous tests of this assumption are lacking because they require quantitative information about the full life-cycles of many species representing different life histories....

Data from: Neural tuning functions underlie both generalization and interference

Ian S. Howard & David W. Franklin
In sports, the role of backswing is considered critical for generating a good shot, even though it plays no direct role in hitting the ball. We recently demonstrated the scientific basis of this phenomenon by showing that immediate past movement affects the learning and recall of motor memories. This effect occurred regardless of whether the past contextual movement was performed actively, passively, or shown visually. In force field studies, it has been shown that motor...

Data from: Bone-eating Osedax worms lived on Mesozoic marine reptile deadfalls

Silvia Danise & Nicholas D. Higgs
We report fossil traces of Osedax, a genus of siboglinid annelids that consume the skeletons of sunken vertebrates on the ocean floor, from early-Late Cretaceous (approx. 100 Myr) plesiosaur and sea turtle bones. Although plesiosaurs went extinct at the end-Cretaceous mass extinction (66 Myr), chelonioids survived the event and diversified, and thus provided sustenance for Osedax in the 20 Myr gap preceding the radiation of cetaceans, their main modern food source. This finding shows that...

Data from: An experimental comparison of three Towed Underwater Video Systems using species metrics, benthic impact and performance

Emma V. Sheehan, Sandrine Vaz, Erin Pettifer, Nicola L. Foster, Sarah J. Nancollas, Sophie Cousens, Luke Holmes, Jean-Valery Facq, Gregory Germain & Martin J. Attrill
1. Managing ecological systems, which operate over large spatial scales is inherently difficult and often requires sourcing data from different countries and organizations. The assumption might be made that data collected using similar methodologies are comparable but this is rarely tested. Here, benthic video data recorded using different towed underwater video systems (TUVSs) were experimentally compared. 2. Three technically different TUVSs were compared on different seabed types (rocky, mixed ground and sandy) in Kingmere Marine...

Data from: The chicken or the egg? Adaptation to desiccation and salinity tolerance in a lineage of water beetles

Susana Pallarés, Paula Arribas, David T. Bilton, Andrés Millán, Josefa Velasco & Ignacio Ribera
Transitions from fresh to saline habitats are restricted to a handful of insect lineages, as the colonization of saline waters requires specialized mechanisms to deal with osmotic stress. Previous studies have suggested that tolerance to salinity and desiccation could be mechanistically and evolutionarily linked, but the temporal sequence of these adaptations is not well established for individual lineages. We combined molecular, physiological and ecological data to explore the evolution of desiccation resistance, hyporegulation ability (i.e.,...

Data from: Testing the stability of behavioural coping style across stress contexts in the Trinidadian guppy

Thomas M. Houslay, Maddalena Vierbuchen, Andrew J. Grimmer, Andrew J. Young & Alastair J. Wilson
Within populations, individuals can vary in stress response, a multivariate phenomenon comprising neuroendocrine, physiological and behavioural traits. Verbal models of individual stress “coping style” have proposed that the behavioural component of this variation can be described as a single axis, with each individual's coping style being consistent across time and stress contexts. Focusing on this behavioural component of stress response and combining repeated measures of multiple traits with a novel multivariate modelling framework, we test...

Data from: Unravelling the immune signature of Plasmodium falciparum transmission-reducing immunity

Will J. R. Stone, Joseph J. Campo, André Lin Ouédraogo, Lisette Meerstein-Kessel, Isabelle Morlais, Dari Da, Anna Cohuet, Sandrine Nsango, Colin J. Sutherland, Marga Van De Vegte-Bolmer, Rianne Siebelink-Stoter, Geert-Jan Van Gemert, Wouter Graumans, Kjerstin Lanke, Adam D. Shandling, Jozelyn V. Pablo, Andy A. Teng, Sophie Jones, Roos M. De Jong, Amanda Fabra-García, John Bradley, Will Roeffen, Edwin Lasonder, Giuliana Gremo, Evelin Schwarzer … & Matthijs M. Jore
Infection with Plasmodium can elicit antibodies that inhibit parasite survival in the mosquito, when they are ingested in an infectious blood meal. Here, we determine the transmission-reducing activity (TRA) of naturally acquired antibodies from 648 malaria-exposed individuals using lab-based mosquito-feeding assays. Transmission inhibition is significantly associated with antibody responses to Pfs48/45, Pfs230, and to 43 novel gametocyte proteins assessed by protein microarray. In field-based mosquito-feeding assays the likelihood and rate of mosquito infection are significantly...

Data from: Phenotypic and genetic integration of personality and growth under competition in the sheepshead swordtail, Xiphophorus birchmanni

Kay Boulton, Craig A. Walling, Andrew J. Grimmer, Gil G. Rosenthal, Alastair Wilson & Alastair J. Wilson
Competition for resources including food, physical space, and potential mates is a fundamental ecological process shaping variation in individual phenotype and fitness. The evolution of competitive ability, in particular social dominance, depends on genetic (co)variation among traits causal (e.g., behavior) or consequent (e.g., growth) to competitive outcomes. If dominance is heritable, it will generate both direct and indirect genetic effects (IGE) on resource-dependent traits. The latter are expected to impose evolutionary constraint because winners necessarily...

Data from: Analysis of direct and indirect genetic effects in fighting sea anemones

Sarah Lane, Alastair Wilson & Mark Briffa
Theoretical models of animal contests such as the Hawk-Dove game predict that variation in fighting behaviour will persist due to mixed evolutionarily stable strategies (ESS) under certain conditions. However, the genetic basis for this variation is poorly understood and a mixed ESS for fighting can be interpreted in more than one way. Specifically, we do not know whether variation in aggression within a population arises from among-individual differences in fixed strategy (determined by an individual’s...

Data from: Distracted decision-makers: ship noise and predation risk change shell choice in hermit crabs

Svenja Tidau & Mark Briffa
Human induced rapid environmental change such as noise pollution alters the ability of animals to integrate information cues. Many studies focus on how noise impacts single sensory channels but in reality animals rely on multi-modal sources of information. In this study, we investigated the effect of anthropogenic noise and the visual presence of a predator on tactile information gathering during gastropod shell assessment in the European hermit crab Pagurus bernhardus. For hermit crabs, empty gastropod...

Data from: Conformity in the collective: differences in hunger affect individual and group behaviour in fish

Alexander Wilson, Alicia Burns, Emanuele Crosato, Joseph Lizier, Mikhail Prokopenko, Tim Schaerf & Ashley J. W. Ward
Animal groups are often composed of individuals that vary according to behavioural, morphological and internal state parameters. Understanding the importance of such individual-level heterogeneity to the establishment and maintenance of coherent group responses is of fundamental interest in collective behaviour. We examined the influence of hunger on the individual and collective behaviour of groups of shoaling fish, x-ray tetras (Pristella maxillaris). Fish were assigned to one of two nutritional states, satiated or hungry, and then...

Data from: Spatiotemporal variability in the structure of seagrass meadows and associated macrofaunal assemblages in southwest England (UK): using citizen science to benchmark ecological pattern

Dan A. Smale, Graham Epstein, Mark Parry & Martin J. Attrill
Seagrass meadows underpin a variety of ecosystem services and are recognised as globally important habitats and a conservation priority. However, seagrass populations are currently impacted by a range of biotic and abiotic stressors, and many are in decline globally. As such, improved understanding of seagrass populations and their associated faunal assemblages is needed to better detect and predict changes in the structure and functioning of these key habitats. Here, we analysed a large dataset -collected...

Data from: Quantifying Susceptibility of Marine Invertebrate Biocomposites to Dissolution in Reduced pH

Matthew Chadwick, Elizabeth M. Harper, Anaëlle Lemasson, John I. Spicer & Lloyd S. Peck
Ocean acidification threatens many ecologically and economically important marine calcifiers. The increase in shell dissolution under the resulting reduced pH is an important and increasingly recognised threat. The biocomposites that make up calcified hardparts have a range of taxon-specific compositions and microstructures, and it is evident that these may influence susceptibilities to dissolution. Here, we show how dissolution (thickness loss) under both ambient and predicted end-century pH (≈7.6) varies between seven different bivalve mollusc and...

The angle of attack: Rapping technique predicts skill in hermit crab contests

Sarah Lane, Tomas Cornwell & Mark Briffa
Skill, the ability to perform a challenging behaviour well, has been shown to be an important determinant of success in a variety of contexts, including human sports, animal courtship and most recently, animal contests. Because skilful movement requires precise motor control, skill is assumed to be underpinned by traits that determine these abilities. However, while these traits determine an individual’s potential to perform skilful movements (known as technique), this potential may not translate into skilful...

Complex urban environments provide Apis mellifera with a richer plant forage than suburban and more rural landscapes

Graeme Fox, Latha Vellaniparambil, Joshua Sammy, Loreto Ros, Richard Preziosi & Jennifer Rowntree
Growth in the global development of cities, and increasing public interest in beekeeping, has led to rises in the numbers of urban apiaries. Towns and cities can provide an excellent diet for managed bees, with a diverse range of nectar and pollen available throughout a long flowering season and are often more ecologically diverse than the surrounding rural environments. Accessible urban honeybee hives are a valuable research resource to gain insights into the diet and...

Data from: Individual quality and personality: bolder males are less fecund in the hermit crab Pagurus bernhardus

Danielle Bridger, Simon J. Bonner & Mark Briffa
One explanation for animal personality is that different behavioural types derive from different life-history strategies. Highly productive individuals, with high growth rates and high fecundity, are assumed to live life at a fast pace showing high levels of boldness and risk taking, compared with less productive individuals. Here, we investigate among-individual differences in mean boldness (the inverse of the latency to recover from a startling stimulus) and in the consistency of boldness, in male hermit...

Data from: Weak rappers rock more: Hermit crabs assess their own agonistic behaviour

Elizabeth Edmonds & Mark Briffa
Fighting animals use a variety of information sources to make strategic decisions. A neglected potential source of information is an individual's own performance during a fight. Surprisingly, this possibility has yet to be incorporated into the large body of theory concerning the evolution of aggressive behaviour. Here, by experimentally dampening the impact of their shell rapping behaviour, we test for the possibility that attacking hermit crabs monitor their own fight performance. Attackers with dampened raps...

Data from: Weaponry and defenses in fighting animals: how allometry can alter predictions from contest theory

Alexandre Palaoro & Mark Briffa
Theoretical models have been developed to understand how animals decide to withdraw from a contest. They provide testable predictions regarding the relationship between resource holding potential (RHP) and contest duration that assume linear relationships among RHP traits. However, RHP traits might scale with body size according to power laws. Furthermore, investment across different RHP traits may vary. Herein, we provide a model that encompasses the allometric relationship between body size and other RHP traits. First,...

Data from: Faunal response to sea-level and climate change in a short-lived seaway: Jurassic of the Western Interior, USA

Silvia Danise & Steven M. Holland
Understanding how regional ecosystems respond to sea-level and environmental perturbations is a main challenge in palaeoecology. Here we use quantitative abundance estimates, integrated within a sequence stratigraphic and environmental framework, to reconstruct benthic community changes through the 13 myr history of the Jurassic Sundance Seaway in the western United States. Sundance Seaway communities are notable for their low richness and high dominance relative to most areas globally in the Jurassic, and this probably reflects steep...
