Using Gis To Predict Cetacean Strandings Related To Harmful Algal Blooms, Jessica L. Boyd
HCNSO Student Capstones
Exposure to harmful algal bloom (HAB) toxins, such as Karenia brevis, has been linked to cetacean strandings and mortalities. Biological and environmental data from a bottlenose dolphin (Tursiops truncatus) Unusual Mortality Event (UME) in 2004 are compared to those from pilot whale (Globicephala macrorhynchus) mass stranding events in 2013-2014 in western Florida. Geographical Information Systems (GIS) maps have been created by overlaying stranding locations and select K. brevis presence data in order to identify common spatial and temporal trends. Preliminary results indicate that elevated K. brevis levels (>10,000 cells/L) in Sarasota Bay during January-February and November may …
A Review Of Bottlenose Dolphin (Tursiops Truncatus) Vocalizations And An Investigation Into The Existence Of Signature Whistles In A Captive Dolphin Population, Gillian Reily
HCNSO Student Capstones
Individual recognition of conspecifics is important for various reasons in both terrestrial and marine dwelling species and is carried out through a variety of modes including visual, chemical and auditory cues. The ability to recognize individuals acoustically is often carried out through the use of signature vocalizations. The production and use of signature whistles within bottlenose dolphins has been extensively tested since their existence was first suggested almost 50 years ago. From the research, two primary hypotheses have emerged: the signature whistle hypothesis and the whistle repertoire hypothesis. This work discusses the various acoustical means of individual recognition found within …
