▪ Abstract Intraspecific variation in territory size and shape can have strong effects on
population structure and dynamics. The traditional theoretical approach to the study of …

The ecological co‐dependency between plants and hummingbirds is a classic example of a
mutualistic interaction: hummingbirds rely on floral nectar to fuel their rapid metabolisms …

We studied territory characteristics among three neighboring chimpanzee communities in
the Taï National Park, Côte d'Ivoire, and compared them with other chimpanzee populations …

The carrying capacity of an environment is determined partly by how individuals compete
over the available resources. To territorial animals, space is an important resource, leading …

I experimentally manipulated levels of food abundance and density of competitors to
determine how these factors influence the territory size of juvenile steelhead trout …

A widespread feature of territorial systems is that residents almost invariably defeat
challengers. This phenomenon has been explained by the existence of value asymmetries …

Background Assortative mating patterns for mate quality traits like body size are often
observed in nature. However, the underlying mechanisms that cause assortative mating …

Background Urban expansion has been identified as one of the leading drivers of
biodiversity change or loss. For birds, urbanization is specifically related to survival …

Territories are typically defined as spatially exclusive areas that are defended against
conspecifics. Given the spatial nature of territoriality, it is inherently density dependent, but …

Some territorial species have been shown to react more aggressively toward unfamiliar
conspecifics than established neighbors, a behavior referred to as the “dear enemy” …
