Emergence of increased division of labor as a function of group size
Empirical evidence suggests that division of labor in insect societies is positively related to group size both within and across taxa. Response threshold models (RTM) have been commonly used toExpand

Normalized Mutual Entropy in Biology: Quantifying Division of Labor
Division of labor is one of the primary adaptations of sociality and the focus of much theoretical work on self‐organization. This work has been hampered by the lack of a quantitative measure ofExpand

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

Effects of low concentrations of forest‐use pesticides on frog embryos and tadpoles
Management of coniferous forests of eastern Canada may involve spraying with the insecticide femtrothion and the herbicides triclopyr and hexazinone Because ranid frogs breed in ponds that areExpand

Behavioral correlations across activity, mating, exploration, aggression, and antipredator contexts in the European house cricket, Acheta domesticus
Recently, there has been increasing interest in behavioral syndrome research across a range of taxa. Behavioral syndromes are suites of correlated behaviors that are expressed either within a givenExpand

Division of labor in a dynamic environment: response by honeybees (Apis mellifera) to graded changes in colony pollen stores
Abstract A fundamental requirement of task regulation in social groups is that it must allow colony flexibility. We tested assumptions of three task regulation models for how honeybee coloniesExpand

Extensive Natural Intraspecific Variation in Stoichiometric (C:N:P) Composition in Two Terrestrial Insect Species
Abstract Heterotrophic organisms must obtain essential elements in sufficient quantities from their food. Because plants naturally exhibit extensive variation in their elemental content, it isExpand

Lethal and sublethal impacts of pyrethroid insecticides on amphibian embryos and tadpoles
Amphibian populations are potentially sensitive to aquatic contaminants such as pesticides. We exposed embryos and larvae of five amphibians (the frogs Rana sylvatica, Rana pipiens, Rana clamitans;Expand

Relationship Between Condition, Aggression, Signaling, Courtship, and Egg Laying in the Field Cricket, Gryllus assimilis
Sexual selection theory suggests males in good condition should be more successful than males in poor condition when competing with rivals for territories and mates. Understanding how conditionExpand
