Genetics of neotropical fish: from chromosomes to populations

open access: yesFish Physiology and Biochemistry, 2009
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.

Contribution of conservation genetics in assessing neotropical freshwater fish biodiversity

open access: yesBrazilian Journal of Biology
Human activities have a considerable impact on hydrographic systems and fish fauna. The present review on conservation genetics of neotropical freshwater fish reveals that DNA analyses have been promoting increased knowledge on the genetic structure of ...

Fish fauna in a tributary stream of a Neotropical reservoir

open access: yesBrazilian Journal of Biology
Little is known about the fish diversity of streams that flow into Neotropical reservoirs. This is a special case of tributary streams flowing into reservoirs of the Paraná River basin in Brazil.

Contributions to the cytogenetics of the Neotropical fish fauna. [PDF]

open access: yesComp Cytogenet, 2017
Brazilian fish cytogenetics started as early as the seventies in three pioneering research groups, located at the Universidade Estadual Paulista (UNESP, Botucatu, SP), Universidade Federal de São Carlos (UFSCar, São Carlos, SP) and Universidade de São Paulo (USP, São Paulo, SP).

Spinal malformations in a naturally isolated Neotropical fish population. [PDF]

open access: yesPeerJ, 2021
Fish populations that reside in completely isolated freshwater ecosystems are rare worldwide. The Vila Velha State Park (VVSP), located in southern Brazil, is recognized for its arenitic formations called sinkholes (furnas), which are completely isolated. Fish populations within, such as those of Psalidodon aff.

NEOTROPICAL FRESHWATER FISHES: A dataset of occurrence and abundance of freshwater fishes in the Neotropics

open access: yesEcology, 2023
AbstractThe Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large‐scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the ...

CRATER LAKE COLONIZATION BY NEOTROPICAL CICHLID FISHES [PDF]

open access: yesEvolution, 2012
Volcanic crater lakes are isolated habitats that are particularly well suited to investigating ecological and evolutionary divergence and modes of speciation. However, the mode, frequency, and timing of colonization of crater lakes have been difficult to determine.

Functional responses to deforestation in fish communities inhabiting neotropical streams and rivers

open access: yesEcological Processes, 2023
Background Deforestation is a widespread disturbance for neotropical freshwater ecosystems. While biodiversity declines have been associated with deforestation, its functional consequences for stream and river fish faunas remain poorly understood.
