The Biodiversity Laboratories at Saint Joseph's University house more than 100 exotic and endangered animal species-including insects, fish, amphibians, and reptiles. Research in the laboratories is devoted, primarily, to understanding the genetic and ecological bases of animal behavior. In addition, a common theme of the work is the development of techniques for the successful care of exotic a...

With few exceptions, the US Endangered Species Act requires the designation of “critical habitat” for threatened and endangered species. This provides important protections, including a prohibition against adverse modification of designated habitat by federal agencies. Scientists with the US Fish and Wildlife Service develop critical habitat designations, which are then peer reviewed before bei...

Snow-fed river Pinder -a tributary of river Alaknanda in central Himalaya was explored for fish assemblages and habitat specificity. Altogether 27 fish species were reported from three orders, four families and nine genera. Cypriniformes order was dominating followed by Siluriformes and Salmoniformes. Shannon-Weiner diversity index (3.09 to 4.10) and Simpson index of diversity (0.81 to 0.92) of...

Timothy D. Male* and Michael J. Bean Environmental Defense, 1875 Connecticut Avenue, Washington, DC 20009, USA *Correspondence: E-mail: [email protected] Abstract Since passage of the Endangered Species Act in 1973, over 1300 endangered and threatened species have been protected in the USA and its territories. Most species continue to face a significant risk of extinction, but the status of many spe...

Management of threatened and endangered species would seem to be a perfect context for adaptive management. Many of the decisions are recurrent and plagued by uncertainty, exactly the conditions that warrant an adaptive approach. But although the potential of adaptive management in these settings has been extolled, there are limited applications in practice. The impediments to practical impleme...

Ramsar site designation is an acknowledgment of a wetland’s importance. In this study, we conducted biodiversity survey around Natuna to examine its eligibility as the next in Indonesia. This was through sampling for biological resources, using either transect, trapping, or visual observation. We surveyed 32 stations endangered and vulnerable fish, water birds, wetland-dependent species. Sample...

American Peregrine Falcons nesting along Alaska’s upper Yukon River have been studied for nearly 50 years. populations decreased in the 1960’s because widespread use of insecticide DDT caused their eggshells to thin. Thin meant that eggs crushed easily nest, which reduced number baby birds produced. Eventually, were listed as endangered under Endangered Species Act United States (U.S.). After U...

Research into the effects of contaminants on fishes is often conducted on wellstudied model test species, whose responses may be different than those of endangered species. We developed an oligonucleotide microarray consisting of 12 595 genes to examine the effects of the pesticide permethrin on an endangered fish in California, USA, the delta smelt Hypomesus transpacificus. The microarray was ...

—The Cape Fear shiner Notropis mekistocholas is an endangered minnow endemic to the Cape Fear River basin of North Carolina; only five populations remain, all of which are declining. Determining the population densities and habitat requirements of the species is critical to its survival and restoration planning. We conducted population surveys (four sites) and instream microhabitat suitability ...

Ornamental marine species ('OMS') provide valuable income for developing nations in the Indo-Pacific Coral Triangle, from which most of the specimens are exported. OMS culture can help diversify livelihoods in the region, in support of management and conservation efforts to reduce destructive fishing and collection practices that threaten coral reef and seagrass ecosystems. Adoption of OMS cult...
