As a major tributary to the species-rich Ouachita River and one of the few remaining non-channelized rivers in the Alluvial Plains physiographic division, Bayou Bartholomew is a key ecosystem for the freshwater mussel diversity of southeast Arkansas and northeast Louisiana. Bayou Bartholomew is known to contain 16 mussel Species of Greatest Conserv...

... length frequency distribution for each SGCN found in the timed searches is provided in Fig. 6, and individual species profiles are provided below. Cyprogenia aberti: The taxonomy of this species is under review with recent molecular analysis by Chong et al. (2016) indicating the Ouachita River population of Arkansas and Louisiana is an independent evolutionary lineage. The U.S. Fish and Wildlife Service is using the name ...

The present study uses eddy-resolving numerical simulations to investigate how bed roughness affects flow and turbulence structure around an isolated, partially-buried mussel (Unio elongatulus) aligned with the incoming flow. The rough-bed simulations resolve the flow past the exposed part of a gravel bed, whose surface is obtained from a laborator...

Information on freshwater mussel behavior in the sediment is scarce in the Neotropics, especially in the Amazon. Laboratory experiments were used to measure the responses of the mussel Castalia ambigua in relation to combinations of two different morphotypes (Morphotype I with an elongated shell and Morphotype II with a rounded shell) and three dif...

The basic knowledge of freshwater bivalves in the Unionida in some regions of the world is still limited, hindering potential conservation efforts, including in Vietnam. A subset of these mussels, the freshwater bivalve tribe Anodontini, is especially difficult to properly identify morphologically due to intraspecific shell similarity. This study a...

Alternative raw materials unsuitable for human consumption might represent a great interest in animal nutrition. Freshwater bivalves represent an unexploited potential feed resource. The effects of freshwater mussel Sinanodonta woodiana meal on growth performance, histomorphology, and morphometric characteristics of the digestive system of rainbow...

Our understanding of the factors driving the distribution of metacommunities at different scales can be obscured by high variation in species composition between sites and a lack of fine-scale distribution data. Trait-based approaches have long been used to better identify and examine ecological patterns. Most recent studies of riverine metacommuni...
