hypothesis

cort-fitness hypothesis

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

population ecology1 paper
hypothesis

developmental time constraints

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

population ecology1 paper
hypothesis

dominance-impoverishment rule

The rule predicts that species diversity should decrease linearly as the number or abundance of dominant species increases.

community ecology1 paper
hypothesis

double benefit hypothesis

The hypothesis that caddisflies gain nutritional benefits both from consuming conditioned detritus and from consuming algae that grows from nutrients released during detritus processing

community ecology1 paper
hypothesis

dust aversion hypothesis

hypothesis that animals will avoid feeding in areas with high dust deposition

community ecology1 paper
hypothesis

earlier-larger hypothesis

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

population ecology1 paper
hypothesis

enemy release hypothesis

Exotic species benefit from the loss of a subset of their natural enemies during immigration

community ecology1 paper
hypothesis

enemy release hypothesis

community ecology1 paper
hypothesis

enemy-free space hypothesis

community ecology1 paper
hypothesis

habitat saturation

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

population ecology1 paper
hypothesis

hibernation-ageing hypothesis

The hypothesis that ageing is suspended during hibernation, whereby species engaging in torpor periodically suspend ageing and thus live longer than predicted based on body size alone

general ecology1 paper
hypothesis

incipient fasting

The hypothesis that observed declines in excretion rates over time are due to cessation of feeding rather than other factors

general ecology1 paper
hypothesis

invasive species hypothesis

The hypothesis that recent D. geminata blooms are caused by introductions of the species to new geographic areas

general ecology1 paper
hypothesis

iron hypothesis

The proposal that ferric-ferrous iron redox shifts sequester additional phosphorus needed to stimulate nuisance D. geminata blooms in oligotrophic streams

biogeochemistry1 paper
hypothesis

large male advantage

The hypothesis that larger male body size confers fitness advantages in mating success, commonly observed in insects where large size increases competitive ability

evolution1 paper
hypothesis

main effects hypothesis

Hypothesis that social relationships provide direct emotional and behavioral aid that encourages healthy lifestyle changes

general ecology1 paper
hypothesis

misdirected parental care hypothesis

Individuals kill unrelated young to avoid wasting energy on parental care that does not benefit their own offspring

evolution1 paper
hypothesis

mother-knows-best hypothesis

The hypothesis that parent-offspring conflicts can arise when host plants that maximize larval performance differ from plants that increase adult longevity and egg production

evolution1 paper
hypothesis

mother-knows-best hypothesis

population ecology1 paper
hypothesis

mountain passes are higher in the tropics

general ecology1 paper
hypothesis

niche packing theory

Predicts functional and phylogenetic overdispersion in communities where closely related species will compete more strongly than distantly related species, leading to traits being more widely disperse...

community ecology1 paper
hypothesis

optimal cluster size hypothesis

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

population ecology1 paper
hypothesis

pace-of-life hypothesis

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...

population ecology1 paper
hypothesis

parallel trends assumption

methodological1 paper
hypothesis

persistence of protected eggs

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...

population ecology1 paper
hypothesis

personality-dependent dispersal

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

population ecology1 paper
hypothesis

physiological-efficiency hypothesis

population ecology1 paper
hypothesis

relationship strength vs quantity

The concept that quality of social relationships may be more important than number of relationships for stress reduction

community ecology1 paper
hypothesis

reproductive stage vulnerability

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

population ecology1 paper
hypothesis

safe haven hypothesis

Hypothesis that human activity displaces predators creating areas with reduced predation risk for prey species

community ecology1 paper
hypothesis

seasonality hypothesis

Early flowering plant species will display greater resistance to frost than species that flower later

climate1 paper
hypothesis

seasonality hypothesis

Janzen's hypothesis that tropical mountain ranges act as more effective physiological barriers to dispersal than temperate ones due to reduced seasonal temperature variation in the tropics

general ecology1 paper
hypothesis

social fence hypothesis

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

population ecology1 paper
hypothesis

social subordination hypothesis

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

population ecology1 paper
hypothesis

state-dependent safety

population ecology1 paper
hypothesis

state-dependent safety hypothesis

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...

population ecology1 paper
hypothesis

stigma lobe-ovule relationship

The hypothesis that there is a 1:1 anatomical relationship between stigma lobe and ovule in Geranium richardsonii

general ecology1 paper
hypothesis

surface area hypothesis

The hypothesis that habitats with larger surface area provide more niches for arthropods, resulting in greater species richness

community ecology1 paper
hypothesis

taxon invariance

The principle that macroecological patterns should be independent of the taxonomic choices used to define assemblages

community ecology1 paper
hypothesis

terminal allocation

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

population ecology1 paper
hypothesis

thermal mismatch hypothesis

Theory that host susceptibility to pathogens increases as environmental conditions become less favorable for the host

climate1 paper
hypothesis

windows of opportunity

Periods during which plant defenses are relatively reduced, allowing specialized herbivores to exploit host plants behaviorally

behavioral ecology1 paper
