Data from: Evidence of land-sea transfer of the zoonotic pathogen Campylobacter to a wildlife marine sentinel species

Environmental pollution often accompanies the expansion and urbanization of human populations where sewage and wastewaters commonly have an impact on the marine environments. Here, we explored the potential for faecal bacterial pathogens, of anthropic origin, to spread to marine wildlife in coastal areas. The common zoonotic bacterium Campylobacter was isolated from grey seals (Halichoerus grypus), an important sentinel species for environmental pollution, and compared to isolates from wild birds, agricultural sources and clinical samples to...

Data from: Why do frog and toad forelimbs suddenly (but asynchronously) appear every time metamorphosis is near?

Luigi Zechini, Alison Lilley, J. Roger Downie & Patrick T. Walsh
1. The internal development and the emergence of the forelimbs at metamorphosis is a defining feature of anuran amphibians (frogs and toads). However, although forelimb emergence is considered sudden, it is rarely synchronous. Any asynchrony may or may not exacerbate the increased drag that is predicted to occur with the emergence of the forelimbs at metamorphic climax. 2. Despite the impact forelimb emergence is hypothesized to have on individual survival and life-history evolution, the degree...

Data from: Parasitism in early life: environmental conditions shape intra-brood variation in responses to infection

Hanna M. V. Granroth-Wilding, Sarah J. Burthe, Sue Lewis, Thomas E. Reed, Katherine A. Herborn, Mark A. Newell, Emi A. Takahashi, Francis Daunt & Emma J. A. Cunningham
Parasites play key ecological and evolutionary roles through the costs they impose on their host. In wild populations, the effect of parasitism is likely to vary considerably with environmental conditions, which may affect the availability of resources to hosts for defense. However, the interaction between parasitism and prevailing conditions is rarely quantified. In addition to environmental variation acting on hosts, individuals are likely to vary in their response to parasitism, and the combined effect of...

Data from: Individual variation in the oxidative costs of personality traits

Kathryn Arnold, Katherine Herborn, Aileen Adam, Lucille Alexander, Kathryn E. Arnold & Katherine A. Herborn
1.‘Personality traits’ are behavioural differences between individuals that are stable within individuals. Different combinations of personality traits can correlate with fitness variation but the mechanisms remain unclear. There is the suggestion that personality reflects variation in physiology. For example, ‘fast’ (bold, active, fast exploring) individuals are predicted to maintain a higher metabolic rate than ‘slow’ animals. A raised metabolic rate can result in a proliferation of reactive oxygen species (ROS) which, if unchecked, cause oxidative...

Data from: Determining the phylogenetic and phylogeographic origin of highly pathogenic avian influenza (H7N3) in Mexico

Lu Lu, Samantha J. Lycett & Andrew J. Leigh Brown
Highly pathogenic (HP) avian influenza virus (AIV) H7N3 outbreaks occurred 3 times in the Americas in the past 10 years and caused severe economic loss in the affected regions. In June/July 2012, new HP H7N3 outbreaks occurred at commercial farms in Jalisco, Mexico. Outbreaks continued to be identified in neighbouring states in Mexico till August 2013. To explore the origin of this outbreak, time resolved phylogenetic trees were generated from the eight segments of full-length...

Data from: Behavioural and physiological adaptations to low-temperature environments in the common frog, Rana temporaria

Anna P. Muir, Roman Biek & Barbara K. Mable
Background: Extreme environments can impose strong ecological and evolutionary pressures at a local level. Ectotherms are particularly sensitive to low-temperature environments, which can result in a reduced activity period, slowed physiological processes and increased exposure to sub-zero temperatures. The aim of this study was to assess the behavioural and physiological responses that facilitate survival in low-temperature environments. In particular, we asked: 1) do high-altitude common frog (Rana temporaria) adults extend the time available for larval...

Data from: Genetic basis of continuous variation in the levels and modular inheritance of pigmentation in cichlid fishes

R. Craig Albertson, Kara E. Powder, Yinan Hu, Kaitlin P. Coyle, Reade B. Roberts & Kevin J. Parsons
Variation in pigmentation type and levels is a hallmark of myriad evolutionary radiations, and biologists have long been fascinated by the factors that promote and maintain variation in coloration across populations. Here we provide insights into the genetic basis of complex and continuous patterns of color variation in cichlid fishes, which offer a vast diversity of pigmentation patterns that have evolved in response to both natural and sexual selection. Specifically, we crossed two divergent cichlid...

Data from: Growth trajectory influences temperature preference in fish through an effect on metabolic rate

Shaun S. Killen
Most animals experience temperature variations as they move through the environment. For ectotherms in particular, temperature has a strong influence on habitat choice. While well-studied at the species level, less is known about factors affecting the preferred temperature of individuals. Especially lacking is information on how physiological traits are linked to thermal preference and whether such relationships are affected by factors such feeding history and growth trajectory. This study examined these issues in the common...

Data from: Laboratory colonisation and genetic bottlenecks in the tsetse fly Glossina pallidipes

Marc Ciosi, Daniel K. Masiga & Charles M. R. Turner
Background: The IAEA colony is the only one available for mass rearing of Glossina pallidipes, a vector of human and animal African trypanosomiasis in eastern Africa. This colony is the source for Sterile Insect Technique (SIT) programs in East Africa. The source population of this colony is unclear and its genetic diversity has not previously been evaluated and compared to field populations. Methodology/Principal Findings: We examined the genetic variation within and between the IAEA colony...

Data from: Crater lake habitat predicts morphological diversity in adaptive radiations of cichlid fishes

Hans Recknagel, Kathryn Rebecca Elmer & Axel Meyer
Adaptive radiations provide an excellent opportunity for studying the correlates and causes for the origin of biodiversity. In these radiations, species diversity may be influenced by either the ecological and physical environment, intrinsic lineage effects, or both. Disentangling the relative contributions of these factors in generating biodiversity remains a major challenge in understanding why a lineage does or does not radiate. Here, we examined morphological variation in body shape for replicate flocks of Nicaraguan Midas...

Data from: Aerobic scope predicts dominance during early life in a tropical damselfish

Shaun S. Killen, Matthew D. Mitchell, Jodie L. Rummer, Douglas P. Chivers, Maud C. O. Ferrari, Mark I. McCormick & Mark G. Meekan
A range of physiological traits are linked with aggression and dominance within social hierarchies, but the role of individual aerobic capacity in facilitating aggression has seldom been studied. Further, links previously observed between an individual's metabolic rate and aggression level may be context dependent and modulated by factors such as social stress and competitor familiarity. We examined these issues in juvenile Ambon damselfish, Pomacentrus amboinensis, which display intraspecific competition for territories during settlement on coral...
