Concepts

The hypothesis that relationships between egg and juvenile densities are linear when egg densities are constrained below values where eggs or hatching juveniles suffer density-dependent losses

Females should choose nesting sites that best protect them and their offspring from severe or unpredictable weather events, such as extreme temperatures or high wind

Hypothesis that populations may be buffered from adverse climatic effects when vital rates with high impacts on population growth exhibit the least temporal variability

Assumes that antipredator adaptations evolve together and thus prey may respond to extinct predators as long as they have experience with other predators.

The hypothesis that the more an individual interacts with others, the less likely they are to disperse

The principle asserting an inverse relationship between local population density and average metabolic rate of individuals in a species

The hypothesis that larger flowers produce more seeds due to greater resource allocation or pollinator attraction

The hypothesis that play provides an opportunity to practice and refine skills that will be needed later in adulthood

Population density will be higher in more central populations compared to populations at the range margin

Theory suggesting that forests with low species diversity and even-aged stands tend to undergo periods of widespread dieback

A tendency among scientists to presuppose that there is little conflict in the brood chamber of burying beetles

The ability of animals to compensate for disturbance-driven behavioral changes through unknown mechanisms

Hypothesis predicting that baseline glucocorticoid levels should be negatively associated with long-term survival and/or reproductive success

Limited time available for larval development before habitat drying selects for aggressive behavior

Hypothesis that increased food availability should lead to earlier emergence of larger adults

Condition where all suitable habitat patches are occupied, forcing individuals to remain in natal territories

The hypothesis that there is an optimal egg cluster size that maximizes fitness by balancing benefits and costs of aggregation

Hypothesis proposing that individuals vary in life-history strategies covarying with suites of morphological, physiological and behavioural characteristics, where fast-growing individuals should be mo...

Relationships between egg and juvenile densities are strongest for species where eggs are protected from predation, parasitism, or physical factors that cause mortality or by female or male behavior t...

The tendency to disperse is associated with boldness, sociability, and/or aggressiveness behavioral traits

Different stages of reproduction (gestation, lactation, post-reproduction) may predispose females to different levels of roadkill risk due to varying energy demands and foraging behavior

high density population reduces dispersal because immigration of new individuals will increase negative encounters

Hypothesis that dominant individuals can force subordinates to leave natal territory through aggression or control over resources

Hypothesis stating that differences in body condition, size or energy reserves cause and maintain variation in personality, where individuals in better condition take more risks and those in poorer co...

Changes in trait allocation that occur specifically in the last year or period before death
