Conservation threats and future prospects for the freshwater fishes of Ecuador: A hotspot of Neotropical fish diversity. [PDF]

J Fish Biol, 2021
ABSTRACT Freshwater fish communities in Ecuador exhibit some of the highest levels of diversity and endemism in the Neotropics. Unfortunately, aquatic ecosystems in the country are under serious threat and conditions are deteriorating. In 2018–19, the government of Ecuador sponsored a series of workshops to examine the conservation status of Ecuador's ...
