Florida Non-Native Fish Action Alliance
The Florida Non-Native Fish Action Alliance brings together federal and state agencies, academic institutions, and non-governmental organizations to address the need for documenting and managing the non-native fishes introduced to the state's waters.
Fish Slam - Fall 2016
November 1 - 2, 2016 – Eight teams of fishery biologists from the US Geological Survey (USGS), US Fish and Wildlife Service - Peninsular Florida Fisheries Office and Welaka National Fish Hatchery (USFWS), the National Park Service (NPS), Florida Fish and Wildlife Conservation Commission (FWC), Florida International University (FIU), and Zoo Miami sampled 20 sites for non-native fishes in Palm...
Fish Slam - Spring 2016
May 23, 2016 – Five teams of fishery biologists from the U.S. Geological Survey (USGS), Florida Fish and Wildlife Conservation Commission (FWC), the National Park Service (NPS), Florida Museum of Natural History (FLMNH), University of Florida (UF), and Florida International University (FIU) sampled 12 sites for non-native fishes in Broward and Miami-Dade counties in southeastern Florida.
Lionfish Distribution, Geographic Spread, Biology, and Ecology
Many aspects of lionfish biology are studied at the USGS Wetland and Aquatic Research Center. As part of the U.S. Geological Survey Nonindigenous Aquatic Species database, the distribution of lionfish is tracked over time.
Impacts of Non-Native Fishes in the Florida Everglades
The Florida Everglades is the largest wetland ecosystem in the United States and supports a diverse flora and fauna, including many rare species.
Fish Slam 2015
November 3, 2015 – Five 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), the National Park Service (NPS), and Florida International University (FIU) sampled for non-native fishes in canals, ponds and ditches in and around the Plantation/Davie area of Broward County, FL.

Mycoplasma agassizii in Morafka's desert tortoise (Gopherus morafkai) in Mexico Mycoplasma agassizii in Morafka's desert tortoise (Gopherus morafkai) in Mexico
We conducted health evaluations of 69 wild and 22 captive Morafka's desert tortoises (Gopherus morafkai) in Mexico between 2005 and 2008. The wild tortoises were from 11 sites in the states of Sonora and Sinaloa, and the captive tortoises were from the state-managed Centro Ecológico de Sonora Zoo in Hermosillo and a private residence in the town of Alamos. We tested 88 tortoises for...

Anuran site occupancy and species richness as tools for evaluating restoration of a hydrologically-modified landscape Anuran site occupancy and species richness as tools for evaluating restoration of a hydrologically-modified landscape
A fundamental goal of wetland restoration is to reinstate pre-disturbance hydrological conditions to degraded landscapes, facilitating recolonization by native species and the production of resilient, functional ecosystems. To evaluate restoration success, baseline conditions need to be determined and a reference target needs to be established that will serve as an ecological blueprint...

Mycoplasmosis and upper respiratory tract disease of tortoises: a review and update Mycoplasmosis and upper respiratory tract disease of tortoises: a review and update
Tortoise mycoplasmosis is one of the most extensively characterized infectious diseases of chelonians. A 1989 outbreak of upper respiratory tract disease (URTD) in free-ranging Agassiz's desert tortoises (Gopherus agassizii) brought together an investigative team of researchers, diagnosticians, pathologists, immunologists and clinicians from multiple institutions and agencies. Electron...

Variation in salinity tolerance among larval anurans: implications for community composition and the spread of an invasive, non-native species Variation in salinity tolerance among larval anurans: implications for community composition and the spread of an invasive, non-native species
Amphibians in freshwater coastal wetlands periodically experience acute exposure to salinity from hurricane-related overwash events, as well as chronic exposure associated with rising sea levels. In a comparative experimental approach, we examined whether seven species of anuran amphibians vary in their tolerance to changes in salinity. In a laboratory study, we exposed larval Hyla...

Detection of Mycoplasma agassizii in the Texas Tortoise (Gopherus berlandieri) Detection of Mycoplasma agassizii in the Texas Tortoise (Gopherus berlandieri)
Mycoplasma agassizii causes upper respiratory tract disease (URTD) in Texas tortoises (Gopherus berlandieri). To determine exposure to and shedding of M. agassizii, we collected blood samples and nasal swabs from 40 free-ranging Texas tortoises on public and private lands in Texas, USA, from May to October 2009. We used an enzyme-linked immunosorbent assay (ELISA) to detect M. agassizii...

Linking geology and health sciences to assess childhood lead poisoning from artisanal gold mining in Nigeria Linking geology and health sciences to assess childhood lead poisoning from artisanal gold mining in Nigeria
Background: In 2010, Médecins Sans Frontières discovered a lead poisoning outbreak linked to artisanal gold processing in northwestern Nigeria. The outbreak has killed approximately 400 young children and affected thousands more. Objectives: Our aim was to undertake an interdisciplinary geological- and health-science assessment to clarify lead sources and exposure pathways, identify...
