Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil

Journal of Fish Biology, Volume 108, Issue 2, Page 648-668, February 2026.
Abstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition

Water Parameters and Hydrodynamics in Rivers and Caves Hosting Astyanax mexicanus Populations Reveal Macro‐, Meso‐ and Microhabitat Characteristics

Ecology and Evolution, Volume 16, Issue 1, January 2026.
From 2009 to 2025, we have recorded the physicochemical parameters of the water and the hydrological regimes at localities hosting Astyanax mexicanus cavefish and surface fish populations in Mexico. Sampling 13 caves and 30 surface stations revealed strong signatures of the two macrohabitats, but also significant differences in specific water ...

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 ...

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.

Poeciliidae Bonaparte 1831

Family Poeciliidae Livebearers A large family of small, fresh- and brackish-water fishes distributed across the Americas, from southern USA to Argentina. The majority of species exhibit internal fertilisation and give birth to live young. They also exhibit striking sexual dimorphism, with females being larger and deeper-bodied than males.

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.

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 ...

Morphological Study for Identification Improvement of Poeciliidae Family Based on Gonopodium structures and Morphometric analysis

Journal of Tropical Life Science, 2013
Poeciliidae family consists of small live-bearer fishes with sexual dimorphic. This fishes are widely distributed across Indonesian archipelago, but biological studies on this fish are very limited.
