The Digestive Microbiome Diversity of the Least Killifish, Heterandria formosa, and Its Implications for Host Adaptability to Varying Trophic Levels

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Investigations of environmental factors influence on the gut microbiome of the least killifish reveal high variability in gut microbiomes between disparate sites and higher microbial diversity in healthier habitats as reported by the Florida Department of Environmental Protection. Findings suggests specific microbial taxa that may aid in bioremediation

A new and morphologically distinct population of cavernicolous Poecilia mexicana (Poeciliidae: Teleostei) [PDF]

, 2018
The cave molly, Poecilia mexicana, from the Cueva del Azufre, a sulfur cave in Tabasco, Mexico, ranks among the best-studied cave fishes worldwide, despite being known from a single population only.

Intraspecific ecomorphological variations in Poecilia reticulata (Actinopterygii, Cyprinodontiformes): comparing populations of distinct environments

Iheringia: Série Zoologia, 2015
Morphological variations, according to the principles of ecomorphology, can be related to different aspects of the organism way of life, such as occupation of habitats and feeding behavior.

Visual Lateralisation in Female Guppies Poecilia reticulata Demonstrates Social Conformity but Is Reduced When Observing a Live Predator Andinoacara pulcher

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Visual lateralisation, characterised as an asymmetry in eye use, may offer an advantage to group‐living animals by enabling them to manage two concurrent visual tasks simultaneously. Here, we examined visual lateralisation of Trinidadian guppies (Poecilia reticulata) tested either alone or in groups, in either the presence or absence of a live predator,

Persisting at the Edge of Ecological Collapse: The Impact of Urbanization on Fish and Amphibian Communities From Lake Xochimilco

Environmental DNA, Volume 7, Issue 4, July–August 2025.
ABSTRACT Freshwater ecosystems are globally threatened by habitat loss, pollution, and invasive species, all of which are particularly acute in urban areas. To assess the impacts of urbanization on freshwater biodiversity—specifically the effects of alien species on native primary aquatic vertebrates—we investigated the World Heritage Site, Lake ...

Fish distribution across altitudinal gradients in the Upper Paraguay River Basin: Implications for conservation in the Pantanal region

Conservation Science and Practice, Volume 7, Issue 7, July 2025.
This paper approaches the patterns in fish distribution across the altitudinal gradient in the Upper Paraguay River basin, from uplands to the floodplain. We compiled more than 75,000 available fish records and registered 342 fish species and your distribution along altitudinal gradient. Floodplain portion have higher species diversity than headwaters,
