The Appalachia Darter, Percina gymnocephala, is an endemic fish of the New River drainage in North Carolina, Virginia, and West Virginia. Within lower watershed, this species has a limited distribution range Gauley Greenbrier river drainages, conservation could benefit from population status threat assessments. We documented temporal changes based on historic current survey data. reduction Dart...

Endemic species are frequently assumed to have lower genetic diversity than species with large distributions, even if closely related. This assumption is based on research from the terrestrial environment and theoretical evolutionary modelling. We test this assumption in the marine environment by analysing the mitochondrial genetic diversity of 33 coral reef fish species from five families samp...

Many of the species at greatest risk of extinction from anthropogenic climate change are narrow endemics that face insurmountable dispersal barriers. In this review, I argue that the only viable option to maintain populations of these species in the wild is to translocate them to other locations where the climate is suitable. Risks of extinction to native species in destination areas are small,...

Dr. Min Chuah-Petiot, together with staff of Missouri Botanical GardenAntananarivo station, visited in 2002 the Zahamena National Park northeastern part central Madagascar. They collected epiphyllous liverworts, which are deposited TAN and a set small duplicates were sent to Tamás Pócs for identification, now kept EGR form microslides.
