Última Patch Size and Population Density: the Effect of Immigration Behavior Ecology and Society Bowman, Jeff; Ontario Ministry of Natural Resources; jeff.bowman@mnr.gov.on.ca; Cappuccino, Naomi; Carleton University; ncappucc@ccs.carleton.ca; Fahrig, Lenore; Carleton University; lfahrig@ccs.carleton.ca. Many habitat fragmentation experiments make the prediction that animal population density will be positively related to fragment, or patch, size. The mechanism that is supposed to result in this prediction is unclear, but several recent reviews have demonstrated that population density often is negatively related to patch size. Immigration behavior is likely to have an important effect on population density for species that do not show strong edge effects, for species that have low emigration rates, and during short-term habitat fragmentation experiments. We consider the effect that different kinds of immigration behaviors will have on population density and we demonstrate that only a minority of possible scenarios produce positive density vs. patch size...

Ano: 2002 Diversity and habitat preferences of Carabidae and Staphylinidae (Coleoptera) in two agroecosystems Bragantia Martins,Ivan Carlos Fernandes; Cividanes,Francisco Jorge; Ide,Sergio; Haddad,Gianni Queiroz. The present study had as objective determine the diversity and abundance of adults Carabidae and Staphylinidae in two areas, constituted by forest fragment and soybean/corn crops under conventional tillage and no-tillage systems and to analyze the distribution and preference of those beetles for the habitat. The beetles were sampled with 48 pitfall traps. In both experimental areas, two parallel transects of pitfall traps were installed. Each transect had 100 m in the crop and 100 m in the forest fragment. Four traps were close to each other (1 m) in the edge between the crop and the forest fragment, the other traps were installed each 10 m. The obtained data were submitted to the faunistic analysis and the preference of the species by habitat was obtained...
