Ecological implications from spatial patterns in human-caused brown bear mortality

Assessing Land Use Changes in Areas with High Risk of Human-Brown Bear Conflict in Fars Province

Assessing habitat changes is an important step in the spatial prioritization of management efforts, aimed at reducing conflicts. We assessed landuse/cover change in areas with high risk of human-bear conflict in Fars province. In the first step, we predicted the conflict hotspots, using bear damage incidents, a suit of predictors, and the Ensembles of Small Models (ESMs) approach. In the second...

Nematode Spatial and Ecological Patterns from Tropical and Temperate Rainforests

Large scale diversity patterns are well established for terrestrial macrobiota (e.g. plants and vertebrates), but not for microscopic organisms (e.g. nematodes). Due to small size, high abundance, and extensive dispersal, microbiota are assumed to exhibit cosmopolitan distributions with no biogeographical patterns. This assumption has been extrapolated from local spatial scale studies of a few ...

Human-caused mortality influences spatial population dynamics: Pumas in landscapes with varying mortality risks

An understanding of how stressors affect dispersal attributes and the contribution of local populations to multi-population dynamics are of immediate value to basic and applied ecology. Puma (Puma concolor) populations are expected to be influenced by inter-population movements and susceptible to humaninduced source–sink dynamics. Using long-term datasets we quantified the contribution of two p...

Infant mortality in South Africa - distribution, associations and policy implications, 2007: an ecological spatial analysis

BACKGROUND Many sub-Saharan countries are confronted with persistently high levels of infant mortality because of the impact of a range of biological and social determinants. In particular, infant mortality has increased in sub-Saharan Africa in recent decades due to the HIV/AIDS epidemic. The geographic distribution of health problems and their relationship to potential risk factors can be inv...
