antipredator behavior
Behaviors that reduce the likelihood of predation, including vigilance and evasion tactics
winter survival
Survival of organisms through winter diapause or dormancy, often related to environmental conditions during overwintering
density dependence
Population regulation mechanism where demographic rates depend on population density through competition and resource limitation
maternal care
Parental behaviors including female-pup interactions, vigilance, and antipredator behaviors that influence offspring survival and development
breeding ecology
The study of reproductive behaviors, nesting habitat selection, and breeding success in bird populations
oviposition host plant choice
The selection of specific plants by female insects for egg-laying that affects larval survival and development
dispersal
The movement away from your place of birth and onto another location involving decision to depart, displacement, and settlement
gene flow
Movement of genes between populations through migration and reproduction
habituation
Process by which animals become less responsive to repeated non-threatening stimuli over time
balancing selection
Selection that maintains multiple alleles in a population at frequencies above those expected from mutation alone
cannibalism
Predation behavior where individuals consume members of their own species, particularly common in A. m. nebulosum populations targeting first year hatchlings
demography
environmental stochasticity
Random environmental variation that affects demographic parameters across all individuals in a population simultaneously
trait filtering
Environmental processes that filter trait values admitted by changing abiotic and biotic conditions, maintaining trait distributions through phenotypic plasticity and local adaptation
seed set
instar development
The progression through larval developmental stages with associated changes in size and feeding capacity
reproductive suppression
Reduction in reproductive output of individuals due to presence of other conspecifics, particularly older or dominant individuals
nest thermoregulation
The process by which parent birds maintain optimal temperature conditions for their nestlings through behavioral modifications including incubation, shading, and nest attendance patterns
reproductive senescence
A within-individual process caused by deterioration in molecular and physiological function resulting in a decrease in survival probability and reproductive output with age
functional responses
intrusion competition
Competition where individuals attempt to take over established breeding resources from other pairs
affiliative social relationships
Positive social interactions and bonds between individuals including behaviors like grooming, playing, and proximity maintenance
honeydew production
case construction
Caddisfly larvae ability to construct protective cases from environmental debris using silk-like string
colony life cycle
insect recruitment
Addition of new individuals to insect populations through successful reproduction and development
stalk production
Production of extracellular polymeric stalk material by diatoms when photosynthetic rates exceed cellular growth rates
carcass burial
Burying beetle reproductive strategy where pairs bury small carrion for breeding and larval development
maternal investment
Investment by female bees in offspring through pollen provision size and number of brood cells produced
plant density effects
How plant population density affects individual plant growth, morphology, and susceptibility to herbivory through competition and resource availability
colony establishment
Initial colonization phase when winged aphids establish new colonies on host plants
hibernation ecology
Winter survival strategy of some small mammals that may affect their vulnerability to avalanche disturbance depending on burrow depth and emergence timing
pathogen transmission
Spread of disease between individuals through various mechanisms including spore dispersal
range expansion
root turnover
social transmission
Transmission of parasites among individuals within social mammalian groups
agonistic interactions
clonal reproduction
Vegetative reproduction producing genetically identical individuals, characteristic of quaking aspen forming cohesive clones with limited spatial interdigitation
epidemic dynamics
The temporal progression and patterns of disease spread through host populations
optimal outcrossing distance
Distance range that maximizes pollen fertilization success and offspring survival
positive feedback loop
Mechanism where state and behavior mutually reinforce each other, measured as positive correlation between individual intercept and slope in random regression models.
post-fire recovery period
Period required for sagebrush to recover to pre-fire conditions after burning
synchronization
voltinism
actuarial senescence
The increase in mortality with age, showing broad variation at the intraspecific level
altitudinal migration
aspen regeneration
Growth of new aspen trees through sexual reproduction (seeds) or asexual reproduction (suckering from root systems)
asymptotic growth
Growth pattern characterized by an initial period of mass gain followed by stabilization before hibernation entry
