FishBrain and U.S. Fish and Wildlife Service Partner to Create App-powered Citizen Science Engagement Opportunity Tracking Endangered Species
-
The U.S. Fish and Wildlife Service – the federal government agency dedicated to the conservation of fish, wildlife, plants and their habitats – has teamed up with FishBrain – the world’s largest free-to-use app and social network for anglers – to launch a new feature of the app that will help the American public identify and document threatened, endangered and candidate species.

Conserving imperiled species in the Upper Tennessee River Basin
-
When we think of river life, for many of us a handful of animals may come to mind – trout, smallmouth bass, muskie. But in the Southern Appalachians, waters of the Upper Tennessee River Basin are alive with a whopping 255 species of fish and mussels.

Three new darter species of the Etheostoma percnurum species complex (Percidae, subgenus Catonotus) from the Tennessee and Cumberland River Drainages
-
The federally endangered Duskytail Darter, Etheostoma percnurum Jenkins, is known from only six highly disjunct populations in the Tennessee and Cumberland river drainages of Kentucky, Tennessee, and Virginia. Only four are extant. Variation in morphology including meristics, morphometrics, and pigmentation was examined among the four extant populations and limited specimens from the two extirpated populations (Abrams Creek and South Fork Holston River). Analyses of these data found each of the extant populations is morphologically diagnosable. The few specimens avail- able from Abrams Creek and South Fork Holston River prevented thorough assessment of variation, and these were grouped with their closest geographic counterparts, Citico Creek, and Little River, respectively. Three new morphologi- cally diagnosable species are described: E. sitikuense, the Citico Darter, from Citico Creek, Abrams Creek, and Tellico River (Tennessee River system); E. marmorpinnum, the Marbled Darter, from the Little River and South Fork Holston River (Tennessee River system); and E. lemniscatum, the Tuxedo Darter, from the Big South Fork (Cumberland River system). Each species warrants federal protection as an endangered species.

Genetics Provide New Hope for Endangered Freshwater Mussels
-
A piece of the restoration puzzle to save populations of endangered freshwater mussels may have been found, according to a recent U.S. Geological Survey led study. Local population losses in a river may not result in irreversible loss of mussel species; other mussels from within the same river could be used as sources to restore declining populations.

Endangered Species Act Protections Proposed for Two Appalachian Crayfishes in Kentucky, Virginia and West Virginia
-
Just as the central Appalachian landscape was beginning to undergo changes related to early 20th century mining, logging and population growth, researchers documented a number of crayfish species in the streams of this area known for its natural beauty and diverse wildlife. Two of these crayfishes, the Big Sandy crayfish and the Guyandotte River crayfish, are now in danger of extinction.

A phylogenetic perspective on the distribution of plant diversity
-
Phylogenetic studies are revealing that major ecological niches are more conserved through evolutionary history than expected, implying that adaptations to major climate changes have not readily been accomplished in all lineages. Phylogenetic niche conservatism has important consequences for the assembly of both local communities and the regional species pools from which these are drawn. If corridors for movement are available, newly emerging environments will tend to be filled by species that filter in from areas in which the relevant adaptations have already evolved, as opposed to being filled by in situ evolution of these adaptations. Examples include intercontinental disjunctions of tropical plants, the spread of plant lineages around the Northern Hemisphere after the evolution of cold tolerance, and the radiation of northern alpine plants into the Andes. These observations highlight the role of phylogenetic knowledge and historical biogeography in explanations of global biodiversity patterns. They also have implications for the future of biodiversity.
