Changes in Patterns of Territory and Habitat Overlap in Wood-Warblers Over Evolutionary Time
… how closely related species partition space and habitat on a local scale. Shared ecological traits and strategies of closely related species suggest that they should overlap in space and use similar habitats. However, ecological similarity may result in fitness costs when closely related species …

Habitat overlap and seroprevalence of toxoplasma gondii in wildlife and feral cats in a natural area
… and overnight live trapping. Amount of cat habitat use was classified based on frequency of cat occurrence. Prevalence of T. gondii antibodies was determined using the indirect immunofluorescent antibody test (IFAT) and a positive titer of 1:25. Wildlife species were classified as having a …

Investigating the impacts of donkeys on a communal range in Namaqualand: how much does a donkey "cost" in goat units?
… in the light of the degree of dietary and habitat overlap, which were obtained from field observations. Habitat use was scored using dung frequency transects, and feeding was directly observed. It was found that in the wet season, one donkey eats as much as 5 / 7.6 goats (donkey weight set …

Causes and possible consequences of hybridisation in angelfishes at Christmas Island
… Australia). To achieve this, the abundances, habitat and fitness of the three angelfish parent species and their hybrids have been investigated. Based on 14 years of surveys, C. flavissima was abundant (4.53 per 250 m2 +/- 0.66), whereas C. eibli, C. vrolikii, and all hybrid combinations were …
