On November 20, 2014, eight teams of fishery biologists from the U.S. Geological Survey (USGS), U.S. Fish and Wildlife Service (USFWS), Florida Fish and Wildlife Conservation Commission (FWC), U.S. National Park Service (NPS), and Florida International University (FIU) gathered for a one-day sampling event to collect non-native fishes from canals, ponds and ditches in Miami-Dade County, FL.

Influence of drought on salamander occupancy of isolated wetlands on the southeastern Coastal Plain of the United States Influence of drought on salamander occupancy of isolated wetlands on the southeastern Coastal Plain of the United States

In the southeastern U.S., changes in temperature and precipitation over the last three decades have been the most dramatic in winter and spring seasons. Continuation of these trends could negatively impact pond-breeding amphibians, especially those that rely on winter and spring rains to fill seasonal wetlands, trigger breeding, and ensure reproductive success. From 2009 to 2012, we...

Drought, deluge and declines: the impact of precipitation extremes on amphibians in a changing climate Drought, deluge and declines: the impact of precipitation extremes on amphibians in a changing climate

The Class Amphibia is one of the most severely impacted taxa in an on-going global biodiversity crisis. Because amphibian reproduction is tightly associated with the presence of water, climatic changes that affect water availability pose a particularly menacing threat to both aquatic and terrestrial-breeding amphibians. We explore the impacts that one facet of climate change—that of...

Application of diagnostic tests for mycoplasmal infections of desert and gopher tortoises with management recommendations Application of diagnostic tests for mycoplasmal infections of desert and gopher tortoises with management recommendations

Mycoplasmosis is a transmissible upper respiratory tract disease that has affected plans for management and conservation of wild desert and gopher tortoises in the United States. Although impact of mycoplasmosis on populations of desert and gopher tortoises is unknown, increased prevalence of seropositive animals as well as field observations of clinically ill tortoises have occurred in

Mycoplasma agassizii sp., nov., isolated from the upper respiratory tract of the desert tortoise (Gopherus agassizii) and the gopher tortoise (Gopherus polyphemus). Mycoplasma agassizii sp., nov., isolated from the upper respiratory tract of the desert tortoise (Gopherus agassizii) and the gopher tortoise (Gopherus polyphemus).

Biochemical, serological and molecular genetic studies were performed on seven mycoplasma isolates that were recovered from the upper respiratory tract of clinically ill desert tortoises. The isolates were serologically related to each other but serologically distinct from previously described species. Unique mycoplasma species-specific 16S rRNA nucleotide sequences were found in the...

Seroepidemiology of upper respiratory tract disease in the desert tortoise of California Seroepidemiology of upper respiratory tract disease in the desert tortoise of California

Several factors have combined with an upper respiratory tract disease (URTD) to produce declines on some population numbers of desert tortoises (Gopherus agassizii) in the western USA. This study was designed to determine the seroepidemiology of URTD in a population of wild adult tortoises at the Desert Tortoise Research Natural Area (DTNA) study site in Kern County (California, USA)...
