Development of a Duplex Digital PCR and Validation on eDNA Water Samples for Monitoring of the Asian Swamp Eel (Monopterus albus/Javanensis) and Bullseye Snakehead (Channa aurolineata/Marulius) in Florida, USA, Freshwater Ecosystems

Ecology and Evolution, Volume 16, Issue 2, February 2026.
The Asian swamp eel and bullseye snakehead are two invasive organisms in Florida of ecological concern. In this study, a multiplex digital polymerase chain reaction (dPCR) assay is developed, optimized, and validated on water samples for environmental DNA (eDNA) analysis and monitoring. ABSTRACT Invasive species are a significant threat to a variety of

Phylogeography of Cichla (Cichlidae) in the upper Madera basin (Bolivian Amazon)

Molecular Phylogenetics and Evolution, 2006
The Cichlidae family is one of the most specious andecologically diverse groups of freshwater Wshes inhabitingthe tropical zone (Winemiller et al., 1997). Recentlyassessed using molecular data, the phylogeny of cichlidWshes supports a monophyletic origin for the South Ameri-can faunas and further suggests higher evolutionary ratesamong many Neotropical

Importance and spatial patterns of invisible fisheries in Amazonian clear‐water rivers as revealed by fisher knowledge and collaboration

Conservation Biology, Volume 40, Issue 1, February 2026.
The graphical abstract highlights the research collaboration with fishers through interviews to record fishers' knowledge and participatory monitoring, to provide data on small‐scale fisheries in three clear water rivers (Trombetas, Tapajos and Tocantins).

Growth and mortality of Cichla spp. (Perciformes, Cichlidae) introduced in Volta Grande Reservoir (Grande River) and in a small artificial lake in Southeastern Brazil

Brazilian Journal of Biology
The growth and mortality parameters were estimated through the analysis of length frequency distribution for species of Cichla spp. introduced into a lake in Leme (SP), and in Volta Grande reservoir (SP-MG).

Expanded description of Lamproglena monodi (Copepoda: Lernaeidae), parasitizing native and introduced fishes in Brazil Descrição expandida de Lamproglena monodi (Copepoda: Lernaeidae), parasita de peixes nativos e introduzidos no Brasil

Revista Brasileira de Parasitologia Veterinária, 2012
An occurrence of the copepod Lamproglena monodi Capart, 1944, parasitizing freshwater fishes in Brazil is presented, along with new morphological data. This crustacean was originally described parasitizing several cichlids in Africa. In the present study,

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 ...

Genetic characterization of native and introduced populations of the neotropical cichlid genus Cichla in Brazil

, 2020
A molecular phylogenetic analysis based on mitochondrial 16S ribosomal DNA and Control Region sequences from native and introduced populations was undertaken, in order to characterize the introduction of Cichla (peacock bass or tucunaré) species in ...

Assessing the population structure of Plagioscion squamosissimus (Teleostei, Perciformes, Sciaenidae) from the São Francisco River, Bahia, Brazil, using body morphology and otolith shape signatures

Journal of Fish Biology, Volume 108, Issue 1, Page 69-85, January 2026.
Abstract The south American silver croaker, Plagioscion squamosissimus, holds significant importance for the artisanal fisheries in the sub‐middle and lower courses of the São Francisco River, located in northeastern Brazil. To investigate the population structure of this species along its longitudinal profile, a total of 150 individuals (50 fish per ...
