Genetics of neotropical fish: from chromosomes to populations

Fish Physiology and Biochemistry, 2008
The Neotropical freshwater fish fauna is very rich--according to the most recent catalogue 71 families and 4,475 species have been described. However, only a small amount of general information is available on the composition of Neotropical marine fishes. In Brazil, 1,298 marine species have been recorded.

Fish farming as the main driver of fish introductions in Neotropical reservoirs

Hydrobiologia, 2014
Several human activities may result in or facilitate species introductions. In aquatic environments, species introductions are often associated with the construction of dams. In this study, we use reservoirs of the Neotropical region as a model to determine the main causes of fish species introductions.

Diversification of Neotropical Freshwater Fishes

Annual Review of Ecology, Evolution, and Systematics, 2020
Neotropical freshwater fishes (NFFs) constitute the most diverse continental vertebrate fauna on Earth, with more than 6,200 named species compressed into an aquatic footprint <0.5% of the total regional land-surface area and representing the greatest phenotypic disparity and functional diversity of any continental ichthyofauna. Data from the fossil

Oxygen consumption in weakly electric Neotropical fishes

Oecologia, 2003
Weakly electric gymnotiform fishes with wave-type electric organ discharge (EOD) are less hypoxia-tolerant and are less likely to be found in hypoxic habitats than weakly electric gymnotiforms with pulse-type EOD, suggesting that differences in metabolism resulting from EOD type affects habitat choice.

Comparison of fish and macroinvertebrates as bioindicators of Neotropical streams

Environmental Monitoring and Assessment, 2015
The biomonitoring of aquatic ecosystems in developing countries faces several limitations, especially related to gathering resources. The present study aimed at comparing the responses of fish and benthic macroinvertebrates to environmental change, to identify which group best indicates the differences between reference and impacted streams in southern

Fruit preferences by fishes in a Neotropical floodplain

Biotropica, 2020
AbstractThe diets of frugivorous animals result from the interaction between feeding preference and ecological factors such as availability of alternative resources and interactions with other frugivores. A better understanding of frugivore diets will enable predictions about the vulnerability of plant populations to anthropogenic or natural ...

Detritivory in neotropical fish communities

Environmental Biology of Fishes, 1983
Fish communities of major river systems in South America contain a high proportion of detritivorous fishes in the families Prochilodontidae and Curimatidae. These families include important fish stocks that in some regions comprise over 50 percent of the community ichthyomass.

Adverse effects of herbicides in freshwater Neotropical fish: A review

Aquatic Toxicology, 2022
Although herbicides have been developed to act on the physiological processes of plants, they are responsible for causing deleterious effects on animals. These chemical compounds are widely used throughout the world, but especially in countries that export agricultural products such as Central and South America, their use has increased in recent years.

Ascent of neotropical migratory fish in the Itaipu Reservoir fish pass

River Research and Applications, 2011
AbstractThe Piracema Canal is a complex 10‐km fish pass system that climbs 120 m to connect the Paraná River to the Itaipu Reservoir along the Brazil–Paraguay border. The canal was constructed to allow migratory fishes to reach suitable habitats for reproduction and feeding in tributaries upstream from the reservoir.
