Context-dependent group size choice in fish
The costs and benefits of group membership vary with the size of groups, and individuals are expected to modify their choice of groups in response to ecological factors such as food availability andExpand

Prey approaching predators : a cost-benefit perspective
When faced with the presence of a predator, many species of prey initially approach rather than retreat from such a potential threat. Although seemingly paradoxical, this type of approach behaviourExpand

Geographic variation in multiple paternity within natural populations of the guppy (Poecilia reticulata)
Mating can increase an individual's risk of mortality by predation. In response to predation hazards, males in some species court females less often, but alternatively engage in coerced copulationsExpand

Boldness and behavioral syndromes in the bluegill sunfish, Lepomis macrochirus
In recent years, evidence for interindividual variation in "personality" within animal populations has been accumulating. Personality is defined as consistency in an individual's behavioral responsesExpand

Capture technique and fish personality: angling targets timid bluegill sunfish, Lepomis macrochirus
Size-selective harvesting associated with commercial and recreational fishing practices has been shown to alter life history traits through a phenomenon known as fishing-induced evolution. ThisExpand

Towards a synthesis of frameworks in nutritional ecology: interacting effects of protein, carbohydrate and phosphorus on field cricket fitness
Phosphorus has been identified as an important determinant of nutrition-related biological variation. The macronutrients protein (P) and carbohydrates (C), both alone and interactively, are known toExpand

Male Mate Choice in the Guppy (Poecilia reticulata): Do Males Prefer Larger Females as Mates?
Although females are the choosier sex in most species, male mate choice is expected to occur under certain conditions. Theoretically, males should prefer larger females as mates in species whereExpand

Female mate choice under predation risk in the guppy
Abstract Sexual selection, and thus the evolution of both female mating preferences and preferred male traits, may be constrained by costs associated with mate choice. Recent theoretical modelsExpand

Predator preference for brightly colored males in the guppy: a viability cost for a sexually selected trait
Although conspicuous visual sexual signals, such as bright colors, in males serve to attract females in numerous species, they may also attract the attention of potential predators and thus may beExpand
