The oil spill resulting from the explosion of Deepwater Horizon drilling platform initiated immediate concern for marine wildlife, including common bottlenose dolphins in sensitive coastal habitats. To evaluate potential sublethal effects on dolphins, health assessments were conducted Barataria Bay, Louisiana, an area that received heavy and prolonged oiling, a reference site, Sarasota Florida, where was not observed. Dolphins temporarily captured, veterinary examination, then released....
Skin disease occurs frequently in many cetacean species across the globe; methods to categorize lesions have relied on photo-identification (photo-id), stranding, and by-catch data. The current study used photo-id data from four sampling months during 2009 estimate skin lesion prevalence type occurring bottlenose dolphins (Tursiops truncatus) three sites along southeast United States coast [Sarasota Bay, FL (SSB); near Brunswick Sapelo Island, GA (BSG); Charleston, SC (CHS)]. of was highest...

Inshore common bottlenose dolphins (Tursiops truncatus) are exposed to a broad spectrum of natural and anthropogenic stressors. In response these stressors, the mammalian adrenal gland releases hormones such as cortisol aldosterone maintain physiological biochemical homeostasis. Consequently, dysfunction results in disruption hormone secretion an inappropriate stress response. Our objective herein was develop diagnostic reference intervals (RIs) for commonly associated with (i.e., cortisol,...
Phthalates are chemical additives to common consumer goods including cleaning products, cosmetics, personal care and plastic. Because they not chemically bound these products widely used, the potential for environmental contamination is significant. their metabolites have been associated with endocrine disruption reproductive impairment, among other adverse health effects, in laboratory animals human epidemiologic studies. Common bottlenose dolphins (Tursiops truncatus) vulnerable pollutants...
Phthalates are chemical esters used as additives in common consumer goods, such plastics, household cleaners, and personal care products. not chemically bound to the items which they added can easily leach into surrounding environment. Anthropogenic drivers, coastal plastic pollution wastewater runoff, increase exposure potential for marine fauna. Phthalate free-ranging bottlenose dolphins has been focus of recent study, with indications heightened certain phthalate compounds. The objective...
Abstract Passive acoustics has been used extensively to study bottlenose dolphins; yet very few studies have examined the spatial, temporal, and environmental influences on vocalization types (echolocation, burst pulse sounds, whistles), are long‐term provide high temporal resolution over multiple years. We data from 2013 2018 establish baseline acoustic patterns for dolphins in May River estuary, South Carolina. deployed recorders at six stations during 2013–2014 three 2015–2018, with...
Common bottlenose dolphins (Tursiops truncatus) have previously demonstrated exposure to phthalate esters. Phthalates and esters are commonly added consumer goods enhance desirable properties. As the amount of plastic marine debris increases, these chemicals can easily leach from products into surrounding environment. To evaluate demographic variability in exposure, eight metabolites were quantified urine samples collected free-ranging sampled Sarasota Bay, FL, USA (2010-2019; n = 51)....

Summary Littorinid parasperm develop from a distinctive lineage of germ cells which exhibit process nuclear destruction that has apototic characteristics. Fragments DNA and other breakdown products are incorporated into secretion granules in ultimately find their way to the female bursa copulatrix. Spermatozeugmata stored seminal vesicles and, if unused during breeding season, they recycled by phagocytosis. Attachment between eusperm is facilitated an electrostatic interaction proteins....
Lacaziosis (lobomycosis; Lacazia loboi) is a fungal skin disease that naturally occurs only in humans and dolphins. The first reported case of lacaziosis bottlenose dolphin Tursiops truncatus occurred 1970 Sarasota Bay, Florida, USA, subsequent photo-ID monitoring the Bay population has revealed persistence disease. objectives this study were to estimate prevalence (P) 2 populations on west coast Florida (Sarasota Charlotte Harbor) compare occurrence other published estimates across globe....
The oceans contain trillions of plastic particles, mostly microplastics (i.e., particles < 5 mm diameter; 92.4% particles), which have been detected in organisms at all levels the marine food web. ubiquity debris has created a monumental environmental pollution problem with extensive public health consequences, as more than 40% world’s population lives near coast and shares coastal resources. For decades, common bottlenose dolphins ( Tursiops truncatus ) used sentinels risks for...
Lacaziosis (also known as lobomycosis) is a chronic dermal disease caused by the fungal agent Lacazia loboi, which affects both humans and dolphins. Photographic data have been used to identify lacaziosis-like (LLD) among dolphins in waters of North South America, here we report LLD bottlenose Tursiops truncatus off coast Costa Rica, first reporting Central American waters. During periods 1991 1992 2010 2011, 3 research teams conducted separate dolphin surveys Pacific tropical fiord Golfo...
Abstract Common bottlenose dolphins ( Tursiops truncatus ) are sentinels of environmental health. Skin lesions may indicate disease and can be used to infer population We estimated the prevalence skin identified major lesion types on coastal in Roanoke Sound, North Carolina, over a 3‐year period using photo‐identification.
