Road-edge effects on herpetofauna in a lowland Amazonian rainforest

摘要: The impact of roads on the flora and fauna Neotropical rainforest is perhaps single biggest driver habitat modification population declines in these ecosystems. We investigated road-edge effect a low-use dirt road amphibian reptile abundance, diversity, composition within adjacent lowland Amazonian at San Jose de Payamino, Ecuador. has been closed to vehicle traffic since its construction 2010. Thus, effects from mortality, vehicle-related pollution, noise were not confounding factors. Herpetofauna surveyed using both visual encounter surveys drift fences with pitfall funnel traps varying distances road. Structural microclimate features forest measured each sampling distance. Several variables found differ intermediate interior compared edge conditions, suggesting began attenuate by sam...
