A Census Study of Macro Algae on Patch Reefs near Andros Island, Bahamas (2008, 2009)
Megan Selking, Thomas Meehan (2009) and Navneet Kaur (2008)

This study is intended to identify the major species of macro green algae found on several patch reefs near Andros Island and to determine their approximate percent of cover. It will also create a pressed file of specimens for comparative future studies.

A Comparative Study of Parrotfish Herbivory and its Effects on Algal Cover at Two Patch Reefs off the Eastern Coast of Andros Island, Bahamas (2008, 2009)
Emily Cebalt, Jenna Oberly, Tyler Overmyer and Adam Cagnet

This study is attempting to determine the significance of parrotfish in controlling macro algal cover on patch reefs near Andros Island.  By comparing two similar sized patch reefs, one with high algal cover (Three Sisters), and one with minimal algal cover (Mastic Point), both with little or no sign of Diadema recovery, the role of the second most cited grazer is being assessed.

A Study of the Rebound of the Long-spined Sea Urchin, Diadema, and the Facilitation of Coral Recovery  (2005, 06)
Katie Yentes and Kristi Burns

The long-spined urchin disappeared from the Caribbean due to a virus in the early 1980’s.  Increased green algae density on the barrier and patch reefs were noted almost immediately thereafter.  In the decades since the eradication, short-spined rock urchins have increased dramatically assumedly to occupy the vacated niche space.  However, the herbivory  and mobility of the rock urchins are much less than Diadema.  This scheduled 3-5 year study will monitor the return and affects of the urchins on the reefal areas surrounding Andros Island, Bahamas.

Presented at the Undergraduate Research Conference, Butler University, Indianapolis, IN, April 21, 2006. Presented at the 12th Symposium on the Natural History of the Bahamas, San Salvador Is., June 2007 and has been accepted via peer review for the conference proceedings.
