The understanding of the environmental preferences and life history of a species in its native range provides insights for assessing its potential success in a novel area. Hemiodus orthonops is a migratory fish from the Paraguay and Middle Paraná rivers that invaded the Upper Paraná River through a fish pass, constructed in 2002. The invasion of this fish… (More)
Freshwater fisheries are mainly small-scale activities and occur mostly in developing countries. These fisheries are recognized for its chronic lack of data and incipient knowledge when compared to large-scale fisheries, despite its socioeconomic and food security relevance. Brazil is a good model of small-scale freshwater fisheries country because it… (More)
Seasonal flooding regimes are closely related to the life history of neotropical fish, especially with regard to their reproduction. The classification of fish into reproductive guilds serves to identify broad patterns in reproductive types, which are important in developing management and conservation measures. We tested the hypothesis that the fish… (More)
Due to an unfortunate turn of events, the last author's surname appeared incorrectly in the original publication and should have read Espinola. The correct representation of the authors' names is listed above and should be treated as definitive by the reader.
The mathematical and statistical advances in fitting stock assessment models enabled the emergence of the paradigm of “integrated analysis”, which fits all available data to a single model of population dynamics that traditionally has total catch as the only forcing function of the system. This approach, however, allowed us to include, in a flexible way,… (More)
