Concepts

Hamilton's theory that fitness should be stripped of all components which can be considered as due to the individual's social environment, leaving the fitness he would express if not exposed to any of...

Pikas as island species restricted to talus habitat and high alpine mountain tops

Framework for discussing how landslide processes contribute to geomorphological development of different types of terrain

The concept that masculinity is performed and constructed rather than innate, revealed through character staging and cultural fabrication

Physical principle balancing soil transport and production processes to predict soil thickness evolution

The principle that mass cannot be created or destroyed, applied to nutrient cycling as consumption - growth - egestion = excretion

The balance between including biological detail to improve accuracy versus introducing parameter uncertainty that can reduce forecast skill

The ethical responsibilities that supervisors carry when sending workers into the field, including duties of promoting safety, ensuring equitable access, and continuing to learn and improve

Physical limitations imposed by body structure that affect foraging efficiency and resource use

Theoretical framework positing natural selection simultaneously occurs at multiple levels of biological organization, and at levels other than only the gene

A theoretical view operating on the premise that each person has a specific status or position within society, with different levels of socioeconomic status having different challenges with leisure co...

The influence of early life environment on later life history decisions

Random changes in allele frequencies due to sampling effects

The tendency for species to retain ancestral ecological requirements rather than evolving new ones

Theory predicting that parents should allocate investment amongst their progeny according to an optimum at which their own (i.e., the parents') fitness is maximized

Hypothesis positing that a series of behavioural and physiological axes of variation correlates with the individual slow-fast continuum

Correlations between boldness and an individual's willingness to face risk for food, linked to growth rate

The conflicting pressures parent birds face between maintaining optimal nest conditions and foraging to meet metabolic needs

Theoretical framework predicting when parents will abandon offspring based on costs and benefits of continued care versus seeking additional mating opportunities

Theoretical framework predicting significant costs to deploying defensive weapons, with plants using defenses when benefits outweigh costs and conserving resources when defense is unnecessary

Moments when political will and available solutions converge to enable policy action

Governance with many centers of decision-making which are formally independent of each other

The differential distribution of power and influence across individual workers, supervisors, institutions, and social context that shapes field safety outcomes

Landscapes encountered in daily life through interaction with material and people that are invested with power, where people develop special meanings and symbols to understand and approach powerful la...

Model predicting that predators are affected to a greater extent than prey in high stress environments, reducing predation rates

Game theory model where producers invest in developing resources while scroungers exploit those resources without investment

Plant strategy emphasizing rapid resource capture and growth versus conservative resource use

The requirement for specific nutrient ratios results in different limiting nutrients for each life-history trait

Theoretical framework contrasting bottom-up resource limitation versus top-down predator control of community structure

Theory predicting that species with traits conferring ability to most efficiently take up limiting soil resources will have highest abundance in a community

Model assuming limited number of sites suitable for germination and recruitment with only one juvenile per safe site

Mathematical relationships that describe how system properties change with size or scale, typically expressed as power laws

Insects with extended parental behavior intermediate between extremely social and extremely asocial species

Innate sensory responses that form a foundation for higher-level cognitive functioning in animals

Theoretical framework predicting optimal investment in male versus female offspring based on relatedness asymmetries in social insects

A system is typically considered more complex if it contains more parts, more variability or types of parts, more connections or types of connections between parts or more layers of connected meaning

The hypothesis that social structure influences the evolution of individually distinctive communication signals
