Social Environment Influences Performance in a Cognitive Task in Natural Variants of the Foraging Gene Open

Nancy R. Kohn, Christopher J. Reaume, Céline Moreno, James G. Burns, Marla B. Sokolowski , et al. · 2013

In Drosophila melanogaster, natural genetic variation in the foraging gene affects the foraging behaviour of larval and adult flies, larval reward learning, adult visual learning, and adult aversive training tasks. Sitters (for(s)) are mor…

Gene–environment interplay in<i>Drosophila melanogaster</i>: Chronic food deprivation in early life affects adult exploratory and fitness traits Open

James G. Burns, Nicolas Svetec, Locke Rowe, Frédéric Mery, Michael-John Dolan , et al. · 2012

Early life adversity has known impacts on adult health and behavior, yet little is known about the gene–environment interactions (GEIs) that underlie these consequences. We used the fruit fly Drosophila melanogaster to show that chronic ea…

Costs of memory: lessons from ‘mini’ brains Open

James G. Burns, Julien Foucaud, Frédéric Mery · 2010

Variation in learning and memory abilities among closely related species, or even among populations of the same species, has opened research into the relationship between cognition, ecological context and the fitness costs, and benefits of…

Use of Spatial Information and Search Strategies in a Water Maze Analog in Drosophila melanogaster Open

Julien Foucaud, James G. Burns, Frédéric Mery · 2010

Learning the spatial organization of the environment is crucial to fitness in most animal species. Understanding proximate and ultimate factors underpinning spatial memory is thus a major goal in the study of animal behavior. Despite consi…

Diversity of speed-accuracy strategies benefits social insects Open

A test of spatial memory and movement patterns of bumblebees at multiple spatial and temporal scales Open

James G. Burns, James D. Thomson · 2005

Naive bumblebee foragers appear to use movement rules at small spatial and temporal scales, but it is not clear whether these rules determine movement patterns as the scales increase. One strategy for efficient foraging used by bumblebees …

Relationship of Calidris Sandpiper Wing Shape With Relative Fuel Load and Total Migration Distance Open

James G. Burns · 2003

It has proven difficult to support the classic prediction of aerodynamic theory that highly migratory birds should have more pointed wings than less migratory birds. This study extends the search by testing for correlations between wing sh…

A CONSIDERATION OF PATTERNS OF VIRULENCE ARISING FROM HOST-PARASITE COEVOLUTION Open

Troy Day, James G. Burns · 2003

In this article we explore how host survival and fecundity are affected by host-parasite coevolution. We examine a situation in which hosts upon being infected can mount a defensive response to clear the infection, but in which there is a …
