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 EvolThe 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

Coexistence of endemic peacock basses (Cichla) in a Neotropical reservoir (Cichlidae: Cichliformes)
Neotropical Ichthyology, 2022 Abstract Peacock basses (genus Cichla) are predatory fish widely distributed across the Amazon, where two or more species normally coexist in a same drainage. The mechanisms that allow coexistence remain poorly understood, although these species share a number of functional traits and behavioral aspects.

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