The Elton Prize is awarded by the British Ecological Society each year for the best paper in the Journal of Animal Ecology written by an early career author at the start of their research career. The winner of the Elton Prize will receive £250, membership of the BES, a year’s subscription to the Journal of Animal Ecology, and a contribution to the costs incurred in attending the BES Annual Meeting in the UK if they wish to give a presentation on their work. The winner is selected by the Executive Editors of the Journal of Animal Ecology at the end of each year and an announcement is made early in the New Year following.
Those nominated are in the early stages of their research career. Nominations are accepted from authors slightly older where their careers in ecology have been interrupted or have developed later.
If the first named author of a paper meets these conditions and wishes to be considered for this prize they should indicate this when their manuscript has been conditionally accepted.
Winner of the Elton Prize 2015
Animal personality in a foundation species drives community divergence and collapse in the wild
Jonathan N. Pruitt and Andreas P. Modlmeier (Journal of Animal Ecology, 84:6, pp 1461–1468)
Charles Elton once quipped that “Ecology consists of saying what everyone knows in language that nobody can understand.” Maybe that is true for much of ecology, but it is certainly not the case with the paper by Jonathan Pruitt and Andreas Modlmeier “Animal personality in a foundation species drives community divergence and collapse in the wild.” Does everyone know that spiders have personality? And the prose in Pruitt and Modlmeier’s paper is both clear and vigorous, so readers can definitely understand it. The editorial board was impressed by the creativity of Dr. Pruitt’s work, its rigor, and the conceptual ties it made among the sometimes disparate fields of behavioral ecology and community ecology. Indeed, this paper stood out among many excellent papers in JAE in 2015. Therefore, the editorial board is happy to award the 2015 Elton Prize to Dr. Jonathan Pruitt.
Pruitt and Modlmeier examined how personality in the spider Anelosimus studiosus influences a suite of other spider species over 7 years in the field. Either aspect of the study – examining the extended consequences of personality in A. studiosus or tracking spider community dynamics for 7 years – would be interesting enough. But what Pruitt and Modlmeier showed was that the spider communities associated with webs of docile A. studiosus individuals differed from those associated with webs occupied by aggressive A. studiosus individuals, at least initially. Numerous other studies, mostly in plants, have shown how variation among individuals can lead to cascading community- and ecosystem-level consequences, but much of that work has failed to examine the temporal dynamics of communities associated with particular phenotypes. Here, Pruitt and Modlmeier, because they tracked these communities for seven years, are able to examine early succession, convergence, and ultimately the collapse of spider communities. They conclude that it is possible to use the traits of these initial spider species to predict the rate and path of succession, divergence, convergence, and collapse among the rest of the spider community. In sum, these clever experiments and persistent sampling yield novel insights into how the behavior of individuals scales up to influence the dynamics of communities. We now know that such links are common in nature, but few studies have characterized the links so explicitly. This kind of ecology is the kind of ecology that more people should know about, and they will, because it’s written in a language they can understand.
Jonathan Pruitt performed his graduate studies at the University of Tennessee, Knoxville under the direction of Susan Riechert. He then conducted postdoctoral studies at the University of California, Davis with Andy Sih and Jay Stachowicz. He is presently an assistant professor in the Department of Ecology, Evolution and Marine Biology at University of California, Santa Barbara.
The Pruitt Lab’s research explores the ecological consequences of individual variation in behavior for individuals, populations, and communities. His lab uses a variety of invertebrate models, especially social spiders, to address these topics. More deeply, the research considers the role of individual variation in structuring patterns of task allocation within societies and how these patterns impact the long-term performance of groups in contrasting environments. In non-social systems, Pruitt and his lab consider how variation in behavior impacts species interactions within and across multiple trophic levels. These studies have been conducted in a variety of both terrestrial and marine systems.
Winner of the Elton Prize 2014
The 2014 Elton Prize winner is James Maino for his paper Reconciling theories for metabolic scaling co-authored with Michael R. Kearney, Roger M. Nisbet and Sebastiaan A.L.M. Kooijman (Journal of Animal Ecology, 83: 20–29).
Metabolic theory specifies constraints on the metabolic organisation of individual organisms and has important implications for scaling up from individuals to ecosystems. In this paper, James Maino and his co-authors attempt to reconcile different theories to explain this metabolic scaling. They show that two prominent ideas in metabolic scaling are not necessarily mutually exclusive, and they present a modified framework based on the fundamental processes of acquiring and using pools of stored metabolites which allows both intra- and inter-specific comparisons to be made. The editors thought that the paper was innovative and liked that James and his co-authors tested a priori predictions from their parameterised model against a real dataset for mammalian respiration, with encouraging results. This paper made an excellent contribution to the Journal’s recent Special Feature on “Metabolic Constraints and Currencies in Animal Ecology”, and it has already sparked significant interest in this exciting and controversial field of ecology
Our Elton Prize winner, James, was the lead author of this paper and the editors were impressed that this was his first publication written when he was still in the first year of his PhD. James’ PhD is part of a jointly awarded program between the University of Melbourne and Vrije Universiteit (Amsterdam). His research explores patterns in animal life-history that hold across diverse species and looks into what extent they can be explained by universal physical and chemical constraints. James utilises Dynamic Energy Budget theory in combination with large data sources on the diverse life histories of insects to develop mechanistic models of animal bioenergetics. The resulting mechanistic models explain a variety of well-known but poorly understood patterns in biology, from metabolic scaling to U-shaped pupal respiration in insects.
The Editors of Journal of Animal Ecology are pleased to announce that the 2013 Elton Prize winner for papers published in Volume 82 is Chuan Zhao from Chengdu Institute of Biology, Chinese Academy of Sciences.
Chuan’s paper Predatory beetles facilitate plant growth by driving earthworms to lower soil layers is co-authored with John Griffin, Xinwei Wu and Shucun Sun.
In the paper, Zhao and colleagues tested the hypothesis that predators will have negative effects on plants by suppressing detritivores in a Tibetan alpine meadow, and they did this by manipulating predatory beetles and examining indirect effects transmitted through their earthworm prey. The Editors particularly liked the neat design of this experimental study and the interesting results that emerged, which did not accord with conventional theory – the authors discovered that predators actually enhanced the positive effects of detritivores on plants. Moreover, the Editors appreciated that the authors had worked to demonstrate a plausible and interesting mechanism to explain this counter-intuitive result: a non-consumptive effect, by which the largely aboveground predatory beetles drive earthworms deep into the soil in a bid to escape predation risk, leading to increased porosity, water content and available nutrients in the otherwise barren lower soil layer. Overall, this work also adds a completely novel aspect to the highly topical issue of how predators influence plants and ultimately ecosystem functioning in terrestrial ecosystems.
The paper formed part of Chuan Zhao’s PhD dissertation, and he designed the experiment with his advisor, performed all the experimental procedures and examinations, and wrote the first draft of the manuscript. He is currently a research assistant in Chengdu Institute of Biology, Chinese Academy of Sciences, and plans to continue studying trophic interactions in the alpine detritus system. In fact, Chuan has recently published another paper in JAE using the same system.
The Editors of Journal of Animal Ecology are pleased to announce the winner of the Young Investigator Prize 2012 for papers published in Volume 81 is Sonya Auer from the University of Montana.
Sonya’s paper Life histories have a history: effects of past and present conditions on adult somatic growth rates in wild Trinidadian guppies is co-authored with Andrés Lopez-Sepulcre, Thomas Heatherly II, Tyler J. Kohler, Ronald D. Bassar, Steven A. Thomas and David N. Reznick.
In the paper, Auer and colleagues examined the effects of variation in food availability across life stages on growth rates in wild Trinidadian guppies (Poecilia reticulate).The Editors and reviewers liked the elegant study system used, the detailed analyses, and the surprising and fascinating results that emerged from the investigation. The authors found that food availability and population density at different points in guppy development can have contrasting effects on adult somatic growth rate. Previous studies had only examined the effects of environmental variation within and across life stages in isolation, and thus their relative influence and subsequent importance remained unexplored.
Sonya carried out this work during her PhD in the lab of David Reznick at University of California-Riverside, which she completed from in 2011. She is currently a post-doctoral researcher at Montana Cooperative Wildlife Research Unit, University of Montana. Here, her current research focuses on breeding bird responses to extreme weather events and general increases in temperature associated with current climate change. In particular, she is examining how temperature influences avian growth and development and how these effects may differ across species. Finally, she is also looking at how other breeding strategies such as nest site selection are changing in response to increased warming in the southwestern United States.
Philip’s paper Contrasting patterns of individual specialization and trophic coupling in two marine apex predators is co-authored with Michael R. Heithaus and Craig A. Layman and was published in Volume 80, Issue 1, pages 294–305.
This analysis used stable isotopes to reveal the generalist diet of tiger sharks versus a more specialised diet of bull sharks and, furthermore, how individuals within these species could often have specific diets, presumably linked to local resources and competition.
Nelika’s paper was entitled Interacting effects of predation risk and signal patchiness on activity and communication in house mice and was published in Volume 79, Issue 1, pages 88–97.
In this study, Nelika, with co-author Peter Banks, uses the house mouse to examine how the spatial distribution of conspecific scent signals and the perceived level of predation risk from cats affect mouse behaviour and overall activity across a range of spatial scales.
Michael co-authored his paper The sensitive hare: sub lethal effects of predator stress on reproduction in snowshoe hares (Volume 78, Issue 6, pages 1249–1258) with Charles J. Krebs and Rudy Boonstra.
This is the first study in a free-ranging population of mammals to show that elevated, predator-induced, cortisol concentrations in individual females caused a decline in their reproductive output measured both by number and quality of their offspring.
