The freshwaters bivalves of La Plata Basin in the Anthropocene
La Plata Basin, the fifth-largest basin in the world, includes areas of Argentina, Bolivia, Brazil, Paraguay, and Uruguay and is subjected to intensive human activities such as agriculture, mining, and global trade. The basin hosts 83 native bivalves (Hyriidae, Mycetopodidae, Cyrenoididae, and Sphaeriidae), including 29 endemic and at least 3 non-native species (Cyrenidae and Mytilidae). For their role as filter feeders and their dominance in biomass in benthic freshwater ecosystems, freshwater bivalves play a key role in the resilience of aquatic ecosystems. In this review, we discuss the six major global change threats to freshwater ecosystems in the Anthropocene (climate change, flow regulation, pollution, land-use change, invasive species, and overexploitation) using freshwater bivalves of La Plata Basin as a model in South America. Future directions to properly understand the effects of global change and suggestions for the conservation of the freshwater bivalves in the basin are stated.
期刊介绍：
Hydrobiologia publishes original research, reviews and opinions regarding the biology of all aquatic environments, including the impact of human activities. We welcome molecular-, organism-, community- and ecosystem-level studies in contributions dealing with limnology and oceanography, including systematics and aquatic ecology. Hypothesis-driven experimental research is preferred, but also theoretical papers or articles with large descriptive content will be considered, provided they are made relevant to a broad hydrobiological audience. Applied aspects will be considered if firmly embedded in an ecological context.
