BACKGROUND Comparing patterns of terrestrial and marine defaunation helps to place
human impacts on marine fauna in context and to navigate toward recovery. Defaunation …

▪ 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 food value theory of territoriality predicts an inverse relationship between territory size
and food density. However, several non‐mutually exclusive hypotheses can explain this …

The threatened population of Atlantic Coast piping plovers (Charadrius melodus) has
increased under intensive management of predation and disturbance. However, the relative …

Recent research has demonstrated that dispersal distance and the square root of home-
range size covary proportionately across mammal species. I tested whether these findings …

Movement behavior and its relationship to habitat provide critical information toward
understanding the effects of changing environments on birds. The eastern North American …

Population density and home range are the two major ecological characteristics pertaining
to the ecosystem-level energy use by the species. Home range usually grows more rapidly …

The demographic consequences of within‐population variability in predator foraging are not
well understood. We assessed the relationship between the degree of diet specialization …

We conducted a 4-year experiment to assess the impacts of rotational cattle grazing on
rodents and raptors in a mesic coastal grassland in northwestern California. Live-trapping …

Energetic requirements during the breeding season and environmental factors such as food
abundance and habitat quality may influence spatial use of the landscape by adult birds. We …
