BACKGROUND Understanding the ecological consequences of roads and developing ways to mitigate their negative effects has become an important goal for many conservation biologists. Most mitigation measures are based on road mortality and barrier effects data. However, studying fine-scale individual spatial responses in roaded landscapes may help develop more cohesive road planning strategies for...
Mosquito larvae and their predators or pathogens expected to co-exist in every breeding habitat of mosquito ranging from small temporary sites to large permanent sites. Micro invertebrates are more common, prevalent and numerous than macro invertebrates in aquatic habitats. Micro invertebrates are important as food sources for macro invertebrates and fish (Gilbert and Burns, 1999; Hampton and G...
The assumption that mortality risk increases with dispersal distance has rarely been tested. We compared patterns of natal dispersal in the American marten (Martes americana) between a large regenerating forest landscape and an uncut landscape that was dominated by more mature forest to test whether mortality risk increased with dispersal distance, and whether variation in mortality risk influe...
