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

Ecol Evol
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

Do Coexisting Cryptic Species of Predatory Peacock Bass (Cichliformes: Cichlidae) Partition Their Niche?

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT The mechanisms facilitating coexistence of cryptic species in sympatry have long puzzled ecologists. Cryptic species have nearly identical morphology and, therefore, would be presumed to have high niche overlap and potential for interspecific competition and competitive exclusion when resources are limited. Lowland rivers in South America have

Distinct, Depth-Stratified Communities of Heterotrophic, Mixotrophic, and Parasitic Dinoflagellates and Ciliates in the Subarctic Northeast Pacific Euphotic Zone. [PDF]

J Eukaryot Microbiol
ABSTRACT Dinoflagellates and ciliates are important grazers of primary production in the Northeast Pacific but knowledge of their taxonomic composition and depth‐distribution is limited. These organisms also display a variety of heterotrophic feeding modes including heterotrophy, mixotrophy, and parasitism.

Future invasion risk assessment of the peacock bass in Neotropical ecoregions: A conceptual and testable model

Global Ecology and Conservation
Protecting freshwater biodiversity from non-native invasive species and their impacts is crucial for minimising both regional and global deterioration of ecosystem services. The yellow peacock bass Cichla ocellaris, a predatory freshwater fish endemic to

Reproductive biology of the peacock bass Cichla piquiti (Perciformes: Cichlidae), an exotic species in a Neotropical reservoir [PDF]

Neotropical Ichthyology, 2009
To analyze the reproductive biology of the peacock bass Cichla piquiti, 361 specimens were collected bimonthly in the Itumbiara Reservoir, southeast Brazil, from December 2004 to November 2005.

Hematological parameters of three species of the peacock bass (Cichla spp.) from Balbina lake, Presidente Figueiredo, Amazonas, Brazil [PDF]

Brazilian Journal of Biology, 2021
The objective of this study was to characterize and compare the hematological variables (erythrogram, thrombogram, leukogram and plasma metabolites) of three cichlid species: Cichla monoculus, Cichla temensis and Cichla vazzoleri. A total of 45 specimens

Brain morphology of native and invasive Cichla piquiti, the blue peacock bass (Cichliformes: Cichlidae), with ecomorphological insights

Neotropical Ichthyology
The central nervous system (CNS), composed of the encephalon and spinal cord, regulates physiological, motor, and cognitive processes in vertebrates. In Neotropical fishes, however, encephalon morphology and size remain poorly studied, particularly in ...

Reproductive cycle of the Neotropical cichlid yellow peacock bass Cichla kelberi: A novel pattern of testicular development [PDF]

Neotropical Ichthyology, 2013
The present study describes the testicular maturation phases (associating the germ cells development and the morphological changes suffered by the germinal epithelium along the whole year), and the testicular morphology in the yellow peacock bass Cichla ...

Analysis of propagule pressure and genetic diversity in the invasibility of a freshwater apex predator: the peacock bass (genus Cichla) [PDF]

Neotropical Ichthyology, 2014
An important step in invasive biology is to assess biological variables that could be used to predict invasion success. The study of genetics, evolution, and interactions of invasive and native species in invaded ranges provides a unique opportunity to ...
