Concepts

The selective choices made by organisms regarding where to construct nests, influenced by environmental factors that affect offspring survival and reproductive success.

Human activities that impose novel challenges on a wide range of species, which can negatively influence individuals, populations, and communities as well as ecosystems

Social systems where individuals have flexibility in their social behaviors and group membership rather than being obligately social

tendency of an organism to stay in or habitually return to a particular area

The degree to which individuals can be discriminated from one another based on their vocalizations, quantified using information theory

Directed aggression toward conspecifics, increasing spatial distancing from or decreasing huddling with unfamiliar conspecifics

Mating system where males compete with one another over access to matelines consisting of groups of related females

The distribution of individuals across different size or age classes within a population

Reduced fitness in inbred individuals compared to outbred individuals due to expression of deleterious recessive alleles

Acoustic phenomena including subharmonics, biphonation, deterministic chaos, and warbles that occur when vocal production apparatus loses control

Social organization where related females remain together and males typically disperse

Social ranking system based on agonistic interactions where some individuals consistently dominate others

Variation in behavioral expression within individuals across time or contexts

The age at which females first reproduce, an important component of vertebrate life histories with effects on individual fitness and population dynamics

Plasticity that occurs across generations where parental environmental effects influence offspring phenotype or fitness
