It grows erect to Plant Symbol = UNPA approximately 6 feet in height at maturity, and has leaves that can grow to 24 inches in length. The Contributed by: USDA NRCS East Texas Plant leaves are narrow, less than 1 inch in width, and taper Materials Center towards their ends. The ends of the leaves are often brown and curled in appearance. It produces a large seed head, or panicle, during the summer. The panicles are made up of many flat spikelets containing seed. The panicle turns from green to straw colored in late summer as the plant matures. The stem of the plant has bulges, or nodes, near the soil surface. These will often root down and anchor to the soil surface as wind born sediment accumulates around the plant. Sea oats is also rhizomatous. These rhizomes have a scale-like appearance when young, and can be seen as pale yellow, sharp, stiff, protrusions near the base of the plant. Sea oats is very drought tolerant. This species produces a massive root system, and will tolerate salt spray and brief inundation with salt water. It prefers full sun, and thrives in areas with blowing sand, such as dunes along the upper beach front. Burial of the plant’s base by blowing sand actually stimulates plant R.

  • Cyclura Cychlura) in the Exuma Islands, with a Dietary Review of Rock Iguanas (Genus Cyclura)
    Herpetological Conservation and Biology 11(Monograph 6):121–138. Submitted: 15 September 2014; Accepted: 12 November 2015; Published: 12 June 2016. FOOD HABITS OF NORTHERN BAHAMIAN ROCK IGUANAS (CYCLURA CYCHLURA) IN THE EXUMA ISLANDS, WITH A DIETARY REVIEW OF ROCK IGUANAS (GENUS CYCLURA) KIRSTEN N. HINES 3109 Grand Ave #619, Coconut Grove, Florida 33133, USA e-mail: [email protected] Abstract.—This study examined the natural diet of Northern Bahamian Rock Iguanas (Cyclura cychlura) in the Exuma Islands. The diet of Cyclura cychlura in the Exumas, based on fecal samples (scat), encompassed 74 food items, mainly plants but also animal matter, algae, soil, and rocks. This diet can be characterized overall as diverse. However, within this otherwise broad diet, only nine plant species occurred in more than 5% of the samples, indicating that the iguanas concentrate feeding on a relatively narrow core diet. These nine core foods were widely represented in the samples across years, seasons, and islands. A greater variety of plants were consumed in the dry season than in the wet season. There were significant differences in parts of plants eaten in dry season versus wet season for six of the nine core plants. Animal matter occurred in nearly 7% of samples. Supported by observations of active hunting, this result suggests that consumption of animal matter may be more important than previously appreciated. A synthesis of published information on food habits suggests that these results apply generally to all extant Cyclura species, although differing in composition of core and overall diets. Key Words.—Bahamas; Caribbean; carnivory; diet; herbivory; predation; West Indian Rock Iguanas INTRODUCTION versus food eaten in unaffected areas on the same island, finding differences in both diet and behavior (Hines Northern Bahamian Rock Iguanas (Cyclura cychlura) 2011).

Although this is a research laboratory, he knew that I was much more than just a bench scientist. Throughout my career at the University of Florida, he encouraged me to continue to stay active in leadership activities and organizations alongside my research for my thesis. I know that because of his encouragement, I will be able to be more prosperous in the future having a background in being a functional researcher, but also a master of many skills including leadership building, conference planning, and brainstorming. Additionally, the amount of work that he put into this thesis astonishes me to know that he cares so much about how well I present my research that he would stay up into the wee hours of the night to get the right wording down. I would also like to thank my committee members Dr. Sandra Wilson, Dr. Hector Pérez, and Dr. Grady Roberts for their support and guidance during the past three years. It is because of these individuals that I will pursue a career path that enables me to effectively educate students and the public.

IVERSON ,KIRSTEN N. HINES , AND JENNIFER M. VALIULIS 1Department of Biology, Earlham College, Richmond, IN 47374, USA 2Department of Biological Sciences, Florida International University, University Park, Miami, FL 33199, USA 3Department of Biology, Colorado State University, Ft. Collins, CO 80523, USA ABSTRACT: The nesting ecology of the Allen Cays rock iguana was studied on Leaf Cay and Southwest Allen’s Cay (5 U Cay) in the northern Exuma Islands, Bahamas, during 2001 and 2002. Mating occured in mid-May, and females migrated 30–173 m to potential nest sites in mid to late June. Females often abandoned initial attempts at digging nest burrows, and average time from initiation of the final burrow to completion of a covered nest was six days. At least some females completely buried themselves within the burrow during the final stages of burrow construction and oviposition. Females defended the burrow site during the entire time of construction, and most continued that defense for at least three to four weeks after nest completion. Nests were completed between mid-June and mid-July, but for unknown reasons timing was seven days earlier on U Cay than on Leaf Cay. Nest burrows averaged 149 cm in length and terminal nest chambers usually angled off the main burrow. Depth to the bottom of the egg chamber averaged 28 cm, and was inversely correlated with shadiness of the site, suggesting that females may select depths with preferred temperatures (mean, 31.4 C in this study).
