Concepts
19 concepts
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
dispersal
The movement away from your place of birth and onto another location involving decision to depart, displacement, and settlement
habituation
Process by which animals become less responsive to repeated non-threatening stimuli over time
environmental stochasticity
Random environmental variation that affects demographic parameters across all individuals in a population simultaneously
reproductive suppression
Reduction in reproductive output of individuals due to presence of other conspecifics, particularly older or dominant individuals
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
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
hibernation ecology
Winter survival strategy of some small mammals that may affect their vulnerability to avalanche disturbance depending on burrow depth and emergence timing
agonistic interactions
asymptotic growth
Growth pattern characterized by an initial period of mass gain followed by stabilization before hibernation entry
juvenile growth
Mass gain patterns in young animals during their first active season before hibernation
masculinization
The process by which female mammals that develop in male-biased litters show signs of masculinization because they are exposed to testosterone produced by their male siblings in utero
parasite infection
Infection by internal parasites including blood-borne trypanosomes and intestinal parasites that can affect host behavior and physiology
social learning
Learning that occurs through observation or interaction with other individuals
hibernation
A life-history trait that buffers marmots against climate change by allowing them to escape changes in climate and effectively expand their ecological niches
