Sex differences and similarities in urban home ranges and in the accuracy of cognitive maps.
Former research has examined potential human sex differences in spatial abilities or home range size. Both are assumed to have an adaptive function. In this study we combined the investigation of home range size in an urban environment and spatial abilities by accuracy analysis of cognitive maps. Participants (n = 87) drew a sketch of their home range in Vienna depicting all places regularly vi...
متن کاملForaging optimally for home ranges
Economic models predict behavior of animals based on the presumption that natural selection has shaped behaviors important to an animal’s fitness to maximize benefits over costs. Economic analyses have shown that territories of animals are structured by trade-offs between benefits gained from resources and costs of defending them. Intuitively, home ranges should be similarly structured, but tra...
متن کاملHome ranges of raccoon dogs in managed and natural areas
Knowledge of space use is central to understand animals' role in ecosystems. The raccoon dog Nyctereutes procyonoides is considered as one of the most influential alien mesopredator species in Europe, having the potential to cause loss of local biodiversity and act as a vector for zoonotic diseases. We collared 12 animals to study their home range and habitat use in two areas with different man...
متن کاملSexual Differences in Foraging Behavior of Fiddler Crab, Uca sindensis (Decapoda: Ocypodidae)
Fiddler crab females have two small feeding claws while males have only one the other is enlarged and used as a weapon as well as a mate attraction signal.

Data were collected from September 2007 to August 2008 in order to cover a wide range of ecological conditio...
متن کاملHome ranges, habitat and body mass: simple correlates of home range size in ungulates.
The spatial scale of animal space use, e.g. measured as individual home range size, is a key trait with important implications for ecological and evolutionary processes as well as management and conservation of populations and ecosystems. Explaining variation in home range size has therefore received great attention in ecological research. However, few studies have examined multiple hypotheses ...
