Enemy release: loss of parasites in invasive freshwater bivalves Sinanodonta woodiana and Corbicula fluminea

open access: yesEcography, EarlyView.
Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.
