Spotted fever group (SFG) rickettsial species are obligate intracellular tick-borne pathogens that are responsible for important human diseases. Previous reports have demonstrated the feasibility of using recombinant surface cell antigen Sca5/OmpB to elicit protective immunity against homologous challenges using murine models of Mediterranean spotted fever and Rocky Mountain spotted fever. In addition, the feasibility of generating cross-protective immunity against related rickettsial species has also been established, but the molecular basis for these phenomena was not explored. Here, we demonstrate that vaccination of C3H/HeN mice with a recombinant OmpB domain derived from Rickettsia conorii induced high titer humoral immune responses that …


Testosterone Might Not Be Necessary To Support Female Aggression In Incubating Northern Cardinals, M. Susan Devries, Caitlin P. Winters, Jodie M. Jawor Sep 2015

Testosterone Might Not Be Necessary To Support Female Aggression In Incubating Northern Cardinals, M. Susan Devries, Caitlin P. Winters, Jodie M. Jawor

Faculty Publications

Testosterone's (T) influence on male aggression has been well established in many vertebrate species, but the impact of T on female aggressive behaviour is poorly understood. Among birds, a link between T and female aggression is plausible, as females of many species exhibit a seasonal peak in T concentrations at the onset of breeding when social instability is greatest and they may have circulating T through much of the breeding season. However, investigations examining the relationship between T and female aggression are few and have yielded conflicting results, with experimentally or endogenously elevated T supporting aggressive behaviour in females of …


Competition And Habitat Quality Influence Age And Sex Distribution In Wintering Rusty Blackbirds, Claudia Mettke-Hofmann, Paul B. Hamel, Gerhard Hoffman, Theodore J. Zenzal Jr., Anne Pellegrini, Jennifer Malpass, Megan Garfinkel, Nathan Schiff, Russell Greenberg May 2015

Competition And Habitat Quality Influence Age And Sex Distribution In Wintering Rusty Blackbirds, Claudia Mettke-Hofmann, Paul B. Hamel, Gerhard Hoffman, Theodore J. Zenzal Jr., Anne Pellegrini, Jennifer Malpass, Megan Garfinkel, Nathan Schiff, Russell Greenberg

Bird habitat quality is often inferred from species abundance measures during the breeding and non-breeding season and used for conservation management decisions. However, during the non-breeding season age and sex classes often occupy different habitats which suggest a need for more habitat-specific data. Rusty Blackbird (Euphagus carolinus) is a forested wetland specialist wintering in bottomland hardwood forests in the south-eastern U. S. and belongs to the most steeply declining songbirds in the U.S. Little information is available to support priority birds such as the Rusty Blackbird wintering in this threatened habitat. We assessed age and sex distribution and …

Estimating The Sex Composition Of The Summer Flounder Catch Using Fishery-Independent Data, Jason M. Morson, Eleanor A. Bochenek, Eric N. Powell, Emerson C. Hasbrouck, Jennifer E. Gius, Charles F. Cotton, Kristin Gerbino, Tara Froehlich Jan 2015

Models that account for sex-specific behavior and population dynamics are becoming more common in the stock assessment of sexually dimorphic fishes. However, such models can be data intensive and require some knowledge or assumptions about the sex ratio of fishery landings. A recent stock assessment review of Summer Flounder Paralichthys dentatus identified the need to account for sex-specific fishing mortality in the assessment model; however, no data on the sex composition of the catch were available. Fishery-independent, sex-specific information for this species is collected annually by the National Marine Fisheries Service's Northeast Fisheries Science Center during their bottom trawl survey. …


Application Of Otolith Chemical Signatures To Estimate Population Connectivity Of Red Snapper In The Western Gulf Of Mexico, Michelle Zapp Sluis, Beverly K. Barnett, William F. Patterson, James H. Cowan, Alan M. Shiller Jan 2015

Application Of Otolith Chemical Signatures To Estimate Population Connectivity Of Red Snapper In The Western Gulf Of Mexico, Michelle Zapp Sluis, Beverly K. Barnett, William F. Patterson, James H. Cowan, Alan M. Shiller

Faculty Publications

Otolith chemical signatures of Red Snapper Lutjanus campechanus from six nursery regions were used to estimate the sources of recruits to four sampling regions in the western Gulf of Mexico (Gulf) and to estimate whether postsettlement mixing of Red Snapper occurs between the U.S. and Mexican portions of the western Gulf. In a previous study, region-specific otolith signatures (element : Ca ratios: Ba:Ca, Mg:Ca, Mn:Ca, Sr:Ca, and Li:Ca; stable isotope delta values: δ13C and δ18O) were developed based on age-0 Red Snapper (2005–2007 year-classes) sampled from the six nursery areas. In the present study, subadult and …

It is currently unknown how important the Central American countries south of Belize are as a link between manatee populations in the north (Belize and Mexico) and populations in South America. Therefore, apart from knowing where manatees are found, it is important to understand how manatees are using these habitats and if they are moving between countries or distinct population centers. Here we report the results of a multi-national and multiinstitutional collaboration resulting in the first successful capture and satellite tracking of a West Indian manatee in southern Central America.
