Beach Crawl Width As A Predictive Indicator Of Carapace Length In Loggerhead Sea Turtles (Caretta Caretta)., Dawn M. Miller

HCNSO Student Theses and Dissertations

Carapace lengths and widths of nesting loggerhead sea turtles (Caretta caretta) were measured at Pompano Beach and Fort Lauderdale, Florida to determine if plastron and/or track crawl widths were predictive of carapace size. Straight and curved carapace measurements were taken.

Plastron and track crawl width were measured at four points on each crawl: 1) emerging at the tide line; 2) mid-way to the nest; 3) mid-way returning to the surf; and 4) at the tide line returning to the surf. All four measurements were significantly different from each other (P < 0.005) along each crawl. Crawl width was the most variable factor in all comparisons.

Maximum straight carapace length correlated with emergent track …

A Comparison Of Aeration Methods And Diets For Larval Culture Of The Edible Sea Urchin, Tripneustes Ventricosus (Echinodermata: Echinoidea), Ray Wolcott

HCNSO Student Theses and Dissertations

Tripneustes ventricosus (Lamarck 1816), a major near-shore herbivore in the Atlantic and Caribbean, has been harvested for human consumption in the Caribbean for centuries (Lawrence 2001a, b), occasionally at rates that exceed sustainability (Smith & Berkes 1991), and is among the species having economic importance (Lawrence & Bazhin 1998). Tripneustes ventricosus has recently been observed on the forereef controlling macroalgal growth in the absence of Diadema antillarum (Woodley 1999, Aronson & Precht 2000, Haley & Solandt 2001).

Large-scale culturing has the potential to produce T. ventricosus in sufficient numbers to be used for: bioremediation of coral reef degradation, restocking of …

Coral Recruitment To Various Artificial Substrata, Miami Beach, Fl, Nicholas C. Straccione

HCNSO Student Theses and Dissertations

The City of Miami has placed 12 artificial reefs approximately 100m offshore in two parallel transects. The reason for this deployment was to tum a barren seabed into a productive environment for aquatic organisms. The reefs were placed close to the shoreline to allow easy access for snorkellers, divers, and fisherman. Three different types of reef materials were used in constructing the artificial reefs: boulders composed of limestone, concrete shaped as tetrahedrons, and concrete mixed with tire aggregate shaped as tetrahedrons. This study consisted of two separate assessments: I) a survey from two of each of the different reef types …
