Human Pathogen Shown To Cause Disease In The Threatened Elkhorn Coral Acropora Palmata, Kathryn Patterson Sutherland, Sameera Shaban, Jessica L. Joyner, James W. Porter, Erin K. Lipp

Coral reefs are in severe decline. Infections by the human pathogen Serratia marcescens have contributed to precipitous losses in the common Caribbean elkhorn coral, Acropora palmata, culminating in its listing under the United States Endangered Species Act. During a 2003 outbreak of this coral disease, called acroporid serratiosis (APS), a unique strain of the pathogen, Serratia marcescens strain PDR60, was identified from diseased A. palmata, human wastewater, the non-host coral Siderastrea siderea and the corallivorous snail Coralliophila abbreviata. In order to examine humans as a source and other marine invertebrates as vectors and/or reservoirs of the APS pathogen, challenge experiments …


Trace Metals (Cu, Zn, Cd And Pb) In Juvenile Fish From Estuarine Nurseries Along The Portugese Coast, Rita P. Vasconcelos, Patrick Reis-Santos, Anabela Maia, Miguel Ruano, Maria J. Costa Universidade De Lisboa Mar 2011

Trace Metals (Cu, Zn, Cd And Pb) In Juvenile Fish From Estuarine Nurseries Along The Portugese Coast, Rita P. Vasconcelos, Patrick Reis-Santos, Anabela Maia, Miguel Ruano, Maria J. Costa Universidade De Lisboa

Organic and inorganic pollution can impact organisms directly and affect condition, growth and survival of juvenile fish which use estuaries as nurseries, and thereby affect marine adult populations quantitatively and qualitatively. Trace element contamination (Cu, Zn, Cd, Pb) in juveniles of commercial fish Solea solea, Solea senegalensis, Platichthys flesus, Diplodus vulgaris and Dicentrarchus labrax collected in putative nurseries of the main Portuguese estuaries (with diverse intensities and sources of anthropogenic pressures) was determined via atomic absorption spectrometry. Contamination was significantly different among species. Similar levels of contamination were found among estuaries, except for D. vulgaris. Cu and Zn concentrations …


Distribution And Conservation Status Of Antillean Manatees (Trichechus Manatus Manatus) In Honduras, Daniel González-Socoloske, Cynthia R. Taylor, Olivia R. Rendon Thompson Jan 2011

Distribution And Conservation Status Of Antillean Manatees (Trichechus Manatus Manatus) In Honduras, Daniel González-Socoloske, Cynthia R. Taylor, Olivia R. Rendon Thompson

Faculty Publications

The Antillean manatee, Trichechus manatus manatus, is among the most threatened mammals in Honduras, yet the last published study is from 1980. Since then, the North Coast of Honduras has experienced rapid population growth and land cover change possibly causing habitat loss for manatees. We conducted aerial, boat, and interview surveys between 2005-2007 along the northern and remote eastern coasts of Honduras to assess the current status and distribution of manatees. In addition, we compiled all available data on manatee mortality from museum specimens, unpublished reports, and interviews to determine current threats. We averaged 1.2 manatee sightings per survey hour …


Emerging Issues And Methodological Advances In Fisheries Reproductive Biology, Nancy J. Brown-Peterson Jan 2011

Emerging Issues And Methodological Advances In Fisheries Reproductive Biology, Nancy J. Brown-Peterson

Faculty Publications

Although incorporating detailed reproductive data into all stock assessments is not a practical goal, the need to understand how reproductive biology affects population productivity is being increasingly recognized. More research focused on reproductive biology-coupled with a shift towards a resilience perspective in fisheries science-is resulting in challenges to many long-held assumptions; the emergence of important new issues; and identification of the need to improve data and methods used in reproductive studies. Typically, data for reproductive studies are based on an assessment of gonadal development, which is most accurately evaluated with histology. This special section of Marine and Coastal Fisheries contains …
