Concepts

Movement of genes between populations through migration and reproduction

Process by which animals become less responsive to repeated non-threatening stimuli over time

Selection that maintains multiple alleles in a population at frequencies above those expected from mutation alone

Predation behavior where individuals consume members of their own species, particularly common in A. m. nebulosum populations targeting first year hatchlings

Random environmental variation that affects demographic parameters across all individuals in a population simultaneously

Environmental processes that filter trait values admitted by changing abiotic and biotic conditions, maintaining trait distributions through phenotypic plasticity and local adaptation

The number and proportion of developed seeds produced by an individual plant, used as a measure of fecundity

The progression through larval developmental stages with associated changes in size and feeding capacity

Reduction in reproductive output of individuals due to presence of other conspecifics, particularly older or dominant individuals

The process by which parent birds maintain optimal temperature conditions for their nestlings through behavioral modifications including incubation, shading, and nest attendance patterns

A within-individual process caused by deterioration in molecular and physiological function resulting in a decrease in survival probability and reproductive output with age

Competition where individuals attempt to take over established breeding resources from other pairs

Positive social interactions and bonds between individuals including behaviors like grooming, playing, and proximity maintenance

Caddisfly larvae ability to construct protective cases from environmental debris using silk-like string

Addition of new individuals to insect populations through successful reproduction and development

Production of extracellular polymeric stalk material by diatoms when photosynthetic rates exceed cellular growth rates

Burying beetle reproductive strategy where pairs bury small carrion for breeding and larval development

Investment by female bees in offspring through pollen provision size and number of brood cells produced

How plant population density affects individual plant growth, morphology, and susceptibility to herbivory through competition and resource availability

Initial colonization phase when winged aphids establish new colonies on host plants

Winter survival strategy of some small mammals that may affect their vulnerability to avalanche disturbance depending on burrow depth and emergence timing

Spread of disease between individuals through various mechanisms including spore dispersal

Transmission of parasites among individuals within social mammalian groups

Vegetative reproduction producing genetically identical individuals, characteristic of quaking aspen forming cohesive clones with limited spatial interdigitation

The temporal progression and patterns of disease spread through host populations

Distance range that maximizes pollen fertilization success and offspring survival

Mechanism where state and behavior mutually reinforce each other, measured as positive correlation between individual intercept and slope in random regression models.

Period required for sagebrush to recover to pre-fire conditions after burning

The increase in mortality with age, showing broad variation at the intraspecific level

Growth of new aspen trees through sexual reproduction (seeds) or asexual reproduction (suckering from root systems)

Growth pattern characterized by an initial period of mass gain followed by stabilization before hibernation entry
