Abstract/Description
-
Documentary of the discovery, research and and efforts to protect the deep-water Oculina coral reefs off Florida. These Oculina reefs occur exclusively off eastern Florida at depths of 300 ft, and nowhere else on earth. First discovered by Harbor Branch Oceanographic Institution scientists with the Johnson-Sea-Link submersibles in 1975, they were made the first deep-water coral marine protected area in the world in 1984. Conservation efforts continue today to prevent destructive bottom trawl...

First discovered by Harbor Branch Oceanographic Institution scientists with the Johnson-Sea-Link submersibles in 1975, they were made the first deep-water coral marine protected area in the world in 1984. Conservation efforts continue today to prevent destructive bottom trawl fisheries from fishing within the Oculina Habitat Area of Particular Concern. Funding by the LINK foundation. Dedicated to Dr. Robert Avent & Edwin Link

Abstract/Description
-
Worldwide research of bottlenose dolphins (Tursiops truncatus) has led to varied definitions and terminology regarding ways to group dolphins for study and management. An understanding of the demographic history and population structure of bottlenose dolphins residing within the Indian River Lagoon Estuary System (IRLES), Florida, is needed to help define the IRLES dolphin population: ecotype, population, or community. Using mitochondrial DNA sequencing and microsatellite genotyping, this...
Show moreWorldwide research of bottlenose dolphins (Tursiops truncatus) has led to varied definitions and terminology regarding ways to group dolphins for study and management. An understanding of the demographic history and population structure of bottlenose dolphins residing within the Indian River Lagoon Estuary System (IRLES), Florida, is needed to help define the IRLES dolphin population: ecotype, population, or community. Using mitochondrial DNA sequencing and microsatellite genotyping, this study detected: (1) genetic differentiation between estuarine and coastal individuals (FstmtDNA=0.414, Fstmsat=0.057; p<0.05; K=2), (2) genetic differentiation between the Indian River Lagoon (IRL) and Mosquito Lagoon (ML) (FstmtDNA=0.0201, Fstmsat=0.0234; p<0.09), and (3) minute undefined sub-structure within the IRLES (FstmtDNA=-0.00 -0.0379, Fstmsat=0.00 - vii 0.0445; p>0.1). Additionally, within ML this study detected non-mixing cohabitation of two potential ecotypes, estuarine and coastal. These findings raise many questions regarding how dolphins are presently categorized and managed which are critical to population assessments including abundance, vital rates, and health.
