Trophic diversity in the evolution and community assembly of loricariid catfishes

open access: yesBMC Evolutionary Biology, 2012
Background The Neotropical catfish family Loricariidae contains over 830 species that display extraordinary variation in jaw morphologies but nonetheless reveal little interspecific variation from a generalized diet of detritus and algae.

Morphometric Traits, Length–Weight Dynamics and Condition Indices of Invasive Vermiculated Sailfin Catfish (Pterygoplichthys disjunctivus) in Bangladesh: Management Implications

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT The vermiculated sailfin catfish (Pterygoplichthys disjunctivus), an invasive species, has rapidly proliferated in Bangladesh's freshwater ecosystems, threatening native biodiversity. This study examined its morphometric traits, length–weight dynamics, condition factors and relative weight over a one‐year period (August 2023–July 2024) in the ...

The Ecological Memory of Fish Assemblages in Tropical Agroecosystems With Different History of Landscape Changes

open access: yesFreshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT Environmental changes can have persistent effects on the local and regional dynamics of multispecies assemblages. However, the extent of historical legacies on current diversity patterns may depend on the trajectory and intensity of the environmental change. Here, we investigate how persistent decadal land use and land cover (LULC) changes are

Local Environmental Variables Predict Fish Species Richness and Composition in Sand Beaches of a Neotropical River

open access: yesRiver Research and Applications, Volume 41, Issue 9, Page 1949-1958, November 2025.
ABSTRACT Local and regional species diversity is influenced by historical factors, resource availability, biotic interactions, the presence of resources, and adequate environmental conditions. We evaluated the effects of local environmental variables and spatial structure on fish species richness and composition along sandy beaches of a Neotropical ...

<b>Haematological assessment of four amazonian ornamental armoured catfish (Teleostei, Loricariidae) [PDF]

open access: yesActa Scientiarum. Biological Sciences, 2018
The aim of this study was to characterize the haematological profile of four Amazonian ornamental freshwater armoured catfish: acari-bola (Peckoltia oligospila - L06), acari-pleco (Cochliodon sp. - L145), acari-canoa (Lasiancistrus saetiger - L323) and acari-assacu (Pseudocanthicus spinosus - L160).

Chromosomal distribution of the retroelements Rex 1, Rex 3 and Rex 6 in species of the genus Harttia and Hypostomus (Siluriformes: Loricariidae)

open access: yesNeotropical Ichthyology
The transposable elements (TE) have been widely applied as physical chromosome markers. However, in Loricariidae there are few physical mapping analyses of these elements.

Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 6, Page 1501-1518, November 2025.
Investigating the systematics and biogeography of Neotropical catfishes of the genus Rhamdia refined phylogenetic hypotheses, including deep paraphyly of Rhamdia laticauda, supported northward dispersal catalyzed by emergence of the Panamanian Isthmus and imply that cave colonization is widespread, convergent, and recent, with established cave‐dwelling
