Impacts Of Oil Exposure During Early Life Development Stages In Sheepshead Minnows (Cyprinodon Variegatus) Under Different Environmental Factors, Danielle Simning Dec 2017

Impacts Of Oil Exposure During Early Life Development Stages In Sheepshead Minnows (Cyprinodon Variegatus) Under Different Environmental Factors, Danielle Simning

Master's Theses

The release of approximately 5 million barrels of crude oil into the northern Gulf of Mexico during the 2010 Deepwater Horizon oil spill jeopardized estuarine ecosystem health from Texas to Florida. These estuarine habitats, which serve as nurseries for many important fisheries are also prone to rapid fluctuations in environmental stressors such as oxygen concentration, and salinity. The consequence of combined exposure to crude oil and suboptimal environmental factors during early life stage development of fish is still largely unknown. The objective of this project was to investigate the impacts of exposure to crude oil in combination with varying environmental …


The Ontogeny Of Whistle Production In Infant Atlantic Bottlenose Dolphins (Tursiops Truncatus) During The First Thirty Days Of Life, Brittany Leigh Jones Aug 2014

The Ontogeny Of Whistle Production In Infant Atlantic Bottlenose Dolphins (Tursiops Truncatus) During The First Thirty Days Of Life, Brittany Leigh Jones

Master's Theses

The manner in which dolphin calves acquire their whistle repertoire is largely unknown. This paper focuses on whistle development in four bottlenose dolphin calves during the first thirty days of life in order to increase our understanding of the early emergence of whistles and whistle-like vocalizations. The acoustic parameters of whistle-type vocalizations (i.e., whistles and whistlesquawks) that coincided with a bubblestream emission from the focal calf and/or its mother were analyzed, as were the behavioral states of the mother-calf pair during the emission of such vocals. Mother and calf whistle rates are inversely related, with the mother whistling more often …
