Anthropogenic climate change is warming global temperatures, with significant implications
for salmonid fishes that depend on the availability of cold water during one or more life …

The present study is a full review of the non-native freshwater fish species introduced into
Argentina and their relationship to the main environmental features and introduction vectors …

Longitudinal movement plays fundamental role in habitat colonization and population
establishment of many riverine fish species. Movement patterns of amphidromous fish …

Salmonid introductions for sport fishing and, more recently, for farming, have had a large
impact on freshwater ecosystems in many regions worldwide. In Patagonia, both activities …

This work aimed to study the reproductive traits of the southernmost landlocked population
of Galaxias maculatus living under extreme environmental conditions (54.5° S). Individuals …

Ecological processes that are behind distributions of species that inhabit isolated localities,
complex disjunct distributions, remain poorly understood. Traditionally, vicariance and …

Free-living species often receive greater conservation attention than the parasites they
support, with parasite conservation often being hindered by a lack of parasite biodiversity …

The Patagonian steppe is a vast territory with a diverse array of aquatic environments with
low fish richness, including several exotic species which are mostly salmonids. Unlike the …

Understanding of trophic structure and flow of energy within river systems is essential for
informed management of these ecosystems and conservation of native fish fauna and …

Understanding the life history of understudied native and threatened fishes is crucial to
develop conservation strategies for freshwater ecosystems. Puye grande (Galaxias platei) is …
