Spread of Amazonian Freshwater Fishes Beyond Their Native Ranges

Fish and Fisheries, Volume 27, Issue 1, Page 56-67, January 2026.
ABSTRACT The spread and establishment of Amazonian species outside their native ranges through activities such as sport fishing, aquaculture, and the ornamental fish industry may lead to ecological changes in recipient ecosystems. We investigated the global distribution of Amazonian freshwater fish (AFF) and conducted a case study in the upper Paraná ...

The molecular basis of color vision in colorful fish: Four Long Wave-Sensitive (LWS) opsins in guppies (Poecilia reticulata) are defined by amino acid substitutions at key functional sites

BMC Evolutionary Biology, 2008
Background Comparisons of functionally important changes at the molecular level in model systems have identified key adaptations driving isolation and speciation.

Fine‐Scale Bioregionalization in a Complex Island System: A Freshwater Perspective From the Greater Antilles

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim The isolated nature of islands makes them particularly vulnerable to climate change. The freshwater fishes of the Greater Antilles remain understudied and are further threatened by habitat fragmentation and the introduction of exotic invasive species.

Population structure of an endemic fish Limia zonata (Cyprinodontiformes: Poeciliinae) in the Maimón River, Dominican Republic

Novitates Caribaea, 2019
The population structure of Limia zonata (Nichols, 1915) was studied in four locations in the Maimón River, Monseñor Nouel province, Dominican Republic. The sex and adult-juveniles ratio was calculated for all sampled localities.

Macro‐Hybrid and Micro‐Hybrid of Fish

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT This study reviews the progress in fish breeding, focusing on distant hybridization and gynogenesis, and introduces the theory of macro‐hybrid and micro‐hybrid. The macro‐hybrid refers to the allo‐progeny derived from distant hybridization, including the allo‐progenies.

Genomic resources for a model in adaptation and speciation research: characterization of the Poecilia mexicana transcriptome

BMC Genomics, 2012
Background Elucidating the genomic basis of adaptation and speciation is a major challenge in natural systems with large quantities of environmental and phenotypic data, mostly because of the scarcity of genomic resources for non-model organisms.

Sulawesi Stream Fish Communities Disconnected From the Sea: Absence of Diadromous and Dominance of Exotic Species

Freshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT Barriers can profoundly alter the composition of stream communities. In the tropical island of Sulawesi, streams are inhabited by a diversity of secondary freshwater fishes, mostly diadromous species. Many streams, however, are modified by human activities for various reasons, involving the construction of barriers that impede fish migration ...

Sexual harassment in live-bearing fishes (Poeciliidae): comparing courting and noncourting species [PDF]

, 2017
Sexual harassment by males has been reported from several live-bearing fishes (Poeciliidae) and has been shown to inflict costs on females. For example, poeciliid females have reduced feeding opportunities when accompanied by a male because females ...

Coercive mating has no impact on spatial learning, cognitive flexibility, and fecundity in female porthole livebearers (Poeciliopsis gracilis)

Journal of Fish Biology, Volume 107, Issue 4, Page 1106-1121, October 2025.
Abstract Coercive mating is a sexual selection strategy that is likely to influence female cognition. Female harassment levels have been linked to altered brain gene expression patterns and brain size evolution, suggesting females may respond to coercive mating by investing energy into “outsmarting” males.
