Machine learning models accurately predict clades of proteocephalidean tapeworms (Onchoproteocephalidea) based on host and biogeographical data. [PDF]

Cladistics
Abstract Proteocephalids are a cosmopolitan and diverse group of tapeworms (Cestoda) that have colonized vertebrate hosts in freshwater and terrestrial environments. Despite the ubiquity of the group, key macroevolutionary processes that have driven the group's evolution have yet to be identified.

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
