Habitat preference and migration patterns of amphibians in German agriculture landscapes: aspects of relevance for exposure assessment to plant protection products
Project
Project code: JKI-GF-08-1191
Contract period: 01.01.2016
- 28.02.2017
Purpose of research: Inventory & Assessment
During the 1980s scientists began to notice the worldwide decline of local amphibian populations. Today, among vertebrates amphibians are the most endangered species (Stuart 2004) and the evaluation of presumed reasons for decreasing amphibian populations is the major focus of numerous studies. Due to the worldwide growing sales of plant production products and ecotoxicity studies of them, their active compounds and metabolites are supposed to be one of the main reasons for declines of amphibian populations. Exposure risks by agrochemical applications in agricultural landscapes depend on species-specific moving pattern and habitat preference of amphibian. Outside the breeding season amphibians can live kilometers away from breeding ponds and on agricultural fields. The habitat preference and moving pattern in time and space in agriculture used landscape are not well known but necessary for quantifying risk of agrochemical exposure on environmentally relevant level. In the project species-specific moving behavior and habitat preferences during and over years are investigated to assess the risk for amphibian by application of agrochemicals.
