The gopher tortoise is a keystone species that creates networks of underground burrows that are home to an additional 350 species, where 60 are vertebrates. Vertebrates have been shown to differ between habitat types and seasonally, but limited information is known about vertebrate associates in our region. This study was one of the first to investigate this in our region of south Florida. This study was designed to investigate factors that may affect the presence of vertebrates at gopher tortoise burrows. Camera data was collected to determine vertebrate presence and if specific vertebrate groups elicit a territorial response from the tortoise, while habitat vegetation surveys and weather data were collected to evaluate seasonality. Statistical analysis showed variation in vertebrate presence both seasonally and by habitat type. Few territorial interactions were observed overall. This study acts as a starting point to increase our understanding of local tortoise populations. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2021. / FAU Electronic Theses and Dissertations Collection

The Monte Cristo area of the Cache National Forest has consistently supported a heavy pocket gopher infestation for many years. In 1957, and several succeeding years, infested range was treated with poisoned grain for pocket gopher control. Nearby range (also infested) was no t treated. Thus, gopher- control l ed range became available for comparative study, with period s of successive annual control of 1, 2, 3, 4, and 5 years. Within each of these areas (designated as treatments) were located two study s ites in 1961 and three in 1962. Within each study site were three sample areas, and just out side each study site were two trap blocks. Half-acre trap blocks were saturated with snap t raps for 3- consecutive days to give a 3-day population index ; this was converted to population per acre by treatments for use with regression analysis. Mound and cast counts, which have been widely used as indicators of there lative abundance of gophers were made on the 1-acre sample areas of ea ch treatment. Within these sample areas line -plot transects were used to obtain in format ion on perennial plant numbers and y i e ld, annual plant abundance, and "bulbed plant" abundance.

Gopher tortoises (Gopherus polyphemus) are keystone species mainly due to their burrow construction. Gopher tortoises can also impact the plants around them, but it is rarely quantifiable due to constraints in dispersal studies including time period and seasonality of fruit. The objective of this study was to measure the effect gut-passage has on a native Florida stone-pitted shrub, the cocoplum bush (Chrysobalanus icaco), as well as to attempt to model the relationship between the gopher tortoise and the plant using our unique field site. This study shows that gut-passage has a significant effect on the germination rate of the cocoplum, allowing it to germinate faster than control groups. This study also found that a model involving covariates relating to tortoise movement as a predictor for cocoplum intensity was favored over a homogeneous null model. We believe the pattern of plants is nonrandom and relates to the gopher tortoise’s seed dispersal. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection
