Heritability and fitness consequences of cannibalism in Harmonia axyridis
We examined environmental (food levels) and genetic (heritability and evolvability) influences on the expression of cannibalism in larvae of the ladybird beetle Harmonia axyridis Pallas (Coleoptera:Expand

SPATIAL STRATIFICATION IN LITTER DEPTH BY FOREST-FLOOR SPIDERS
Abstract Two novel sampling techniques were used to survey the spider community of the leaf litter in a deciduous forest in Kentucky, USA. Using modified pitfall traps and litter-grab techniques, weExpand

Influence of prey availability and conspecifics on patch quality for a cannibalistic forager: laboratory experiments with the wolf spider Schizocosa
Abstract Because cannibals are potentially both predator and prey, the presence of conspecifics and alternative prey may act together to influence the rate at which cannibals prey upon each other orExpand

Foraging theory predicts that a potential prey item is excluded from the forager’s diet if the prey profitability is low, or the risk from predation while obtaining the prey item is high (Stephens &Expand

Rapid Evolution of Lifespan in a Novel Environment: Sex-Specific Responses and Underlying Genetic Architecture
Animal lifespans can vary substantially among closely related species and even among conspecific populations, but it is often difficult to identify environmental and genetic factors producing suchExpand

Evidence of exploitative competition among young stages of the wolf spider Schizocosa ocreata
SummaryPrevious research by many investigators has demonstrated food limitation in both web-building and wandering spiders. Field experiments have tested for exploitative competition for prey inExpand

Genetic architecture underlying convergent evolution of egg-laying behavior in a seed-feeding beetle
Independent populations subjected to similar environments often exhibit convergent evolution. An unresolved question is the frequency with which such convergence reflects parallel genetic mechanisms.Expand

Lifetime reproductive effort is equal between the sexes in seed beetles (Callosobruchus maculatus): dispelling the myth of the cheap male
In the evolution of sexual reproduction, the development of asymmetrical gametes (anisogamy) often leads to the characterisation that males invest less in reproduction than females. This view isExpand

Effects of nectar feeding on cannibalism in striped lynx spiderlings Oxyopes salticus (Araneae: Oxyopidae)
Abstract The timing and nutritional value of a first meal is important for spiderlings, but little is known about what spiderlings specifically consume. For wandering spiders, nectar feeding is aExpand
