Fish biology, ecology, and behavior

Fish biology, ecology, and behavior is a research topic within Nature and Landscape Conservation. Science Explorer counts 28k research works in it since 1950. 10.0% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the biogeography, conservation, and ecological dynamics of Neotropical freshwater fishes, with an emphasis on the Amazon River system. It covers topics such as fish biodiversity, impacts of hydropower dams, aging research using short-lived fish species, tropical river fisheries, electroreception in fishes, and the effects of habitat degradation on fish assemblages. The papers also explore the historical biogeography and evolutionary history of Neotropical freshwater fishes.
