Linking organochlorine contaminants with demographic parameters in free-ranging common bottlenose dolphins from the northern Adriatic Sea

Organochlorine contaminants in body tissue of free-ranging white-tailed eagles from northern regions of Germany.

Concentrations of the organochlorine pesticides hexachlorobenzene (HCB), gamma-hexachlorocyclohexane (gamma-HCH), DDT and its metabolite p,p'-dichlorodiphenyldichloroethylene (DDE), and seven polychlorinated biphenyl (PCB) congeners were analyzed in livers and adipose tissue samples of 145 white-tailed eagles found dead or moribund in Germany from 1979 to 2001. Most birds were found in the regi...

Effects of capture on adrenal steroid and vasopressin concentrations in free-ranging bottlenose dolphins (Tursiops truncatus).

Marine mammals are routinely caught in the wild in an effort to monitor their health. However, capture-associated stress could potentially bias various biochemical parameters used to monitor the health of these wild caught animals. Therefore, the effects of capture were quantified by measuring plasma adrenal steroids and arginine vasopressin (AVP) in free-ranging bottlenose dolphins (Tursiops t...

Phenotyping and comparing the immune cell populations of free-ranging Atlantic bottlenose dolphins (Tursiops truncatus) and dolphins under human care

BACKGROUND Studies suggest that free-ranging bottlenose dolphins exhibit a suppressed immune system because of exposure to contaminants or microorganisms. However, due to a lack of commercially available antibodies specific to marine mammal immune cell surface markers, the research has been indecisive. The purpose of this study was to identify cross-reactive terrestrial-specific antibodies in o...

Trace element concentrations in skin of free-ranging bottlenose dolphins (Tursiops truncatus) from the southeast Atlantic coast.

Concentrations of trace elements (Al, As, Ba, Be, Cd, Co, Cr, Cu, Fe, Li, Mn, Ni, Pb, Sb, Se, Sn, Tl, U, V, Zn) and total mercury (THg) were determined in skin samples collected from free-ranging bottlenose dolphin (Tursiops truncatus) populations. Dolphins were captured in the estuarine waters of Charleston (CHS), South Carolina (n=74) and the Indian River Lagoon (IRL), Florida (n=75) during 2...
