- Title
- A comparison of the red fire ant and gopher tortoise burrow distribution within the FAU preserve.
- Creator
- Nenkova, Anzehla, Frazier, Evelyn
- Abstract/Description
-
The gopher tortoise (Gopherus polyphemus) is considered a threatened species throughout much of its range. Their decline is mainly attributed to habitat fragmentation and destruction. These habitat disturbances commonly favor invasive species such as the red fire ant (Solenopsis invicta). The red fire ant has been detected on aprons of gopher tortoise burrows at the FAU preserve and we would like to evaluate whether the distribution of red fire ants overlaps with that of the tortoises burrows...
Show moreThe gopher tortoise (Gopherus polyphemus) is considered a threatened species throughout much of its range. Their decline is mainly attributed to habitat fragmentation and destruction. These habitat disturbances commonly favor invasive species such as the red fire ant (Solenopsis invicta). The red fire ant has been detected on aprons of gopher tortoise burrows at the FAU preserve and we would like to evaluate whether the distribution of red fire ants overlaps with that of the tortoises burrows. Ant distribution was accessed at the FAU preserve by running 10 random 100m transect lines and placing sardine baits at every 20m interval. Preliminary data suggests that red fire ants were abundant in 70% of the transects; however, we were unable to establish a direct correlation between the distribution of gopher tortoise burrows and that of red fire ants. The ants were tentatively identified to subfamilies and further identification will be performed.

- An Analysis of Gopherus polyphemus Reproduction at the Florida Atlantic University Preserve.
- Creator
- Nguyen, Thuymi, Huffman, Jessica, Frazier, Evelyn, Office of Undergraduate Research and Inquiry
- Abstract/Description
-
Gopherus polyphemus (gopher tortoise) is a threatened keystone species whose burrows benefit over 350 species. Surveys conducted throughout 2010- 2015 at Florida Atlantic University Preserve (FAUP) have found an age gap of ten years and a lack of nests. To update the demographic survey and to examine the population’s reproduction and health, we conducted burrow and nest surveys from May to September 2016 and collected fecal samples to check for endo-parasites. Transects were used to locate...
Show moreGopherus polyphemus (gopher tortoise) is a threatened keystone species whose burrows benefit over 350 species. Surveys conducted throughout 2010- 2015 at Florida Atlantic University Preserve (FAUP) have found an age gap of ten years and a lack of nests. To update the demographic survey and to examine the population’s reproduction and health, we conducted burrow and nest surveys from May to September 2016 and collected fecal samples to check for endo-parasites. Transects were used to locate burrows and measurements were taken to determine population structure. Wire-probing was used to locate nests and feces were tested for endo-parasites. From a total of 261 marked burrows and fecal sampling, results indicated a continuous age range, one nest, and presence of intestinal parasites. Future work will focus on health and reproductive behavior that will improve our understanding of the FAUP gopher tortoise population and may ultimately aid in future conservation methods.

- Abstract/Description

Gopherus polyphemus is a threatened reptile native to the southeastern USA. Previous research suggests the South Florida (SF) climate may allow tortoises to reproduce year-round. Our goal was to evaluate the social interactions and home range of the Florida Atlantic University Preserve (FAUP) tortoise population, with an emphasis on reproductive behavior since minimal information is available.

Show moreGopherus polyphemus is a threatened reptile native to the southeastern USA. Previous research suggests the South Florida (SF) climate may allow tortoises to reproduce year-round. Our goal was to evaluate the social interactions and home range of the Florida Atlantic University Preserve (FAUP) tortoise population, with an emphasis on reproductive behavior since minimal information is available. In this study, 12 FAUP tortoises had radio-transmitters attached and game cameras placed at their burrows. We hypothesized, 1) Gopher tortoise home ranges would differ between males and females, and between vegetation types and 2) Intraspecific gopher tortoise interaction frequencies would differ between vegetation types. Movement data has been mapped for 10 tortoises to reveal home ranges differ between sex and vegetation type. Camera data illustrates mounting as the most frequent interaction in the scrub vegetation. This research can be used to improve conservation efforts for the FAUP population.

- Molecular Characterization of Hepatozoon (Apicomplexa: Adeleorina) Blood Parasite within the Threatened Gopherus Polyphemus Species.
- Creator
- Eusse, Johanna, Cooney, Brian, Frazier, Evelyn
- Abstract/Description
-
The gopher tortoise (Gopherus polyphemus) is a threatened burrowing chelonian endemic to the Southeastern United States. Gopher tortoises are classified as a keystone species due to their construction of extensive burrows, providing shelter to approximately 362 commensal species. Haemogregarines are the most common hemoparasite species found within reptiles. The genus Hepatozoon sp. (Apicomplexa: Adeleorina) has been discovered within gopher tortoises at Jonathan Dickinson State Park (Jupiter...

Gopher tortoises are classified as a keystone species due to their construction of extensive burrows, providing shelter to approximately 362 commensal species. Haemogregarines are the most common hemoparasite species found within reptiles. The genus Hepatozoon sp. (Apicomplexa: Adeleorina) has been discovered within gopher tortoises at Jonathan Dickinson State Park (Jupiter, Florida). Our research focus is to conduct molecular analysis on the 18S rRNA region of Hepatozoon sp. within blood samples and to determine how this species found is related to other known Hepatozoon species. This molecular characterization study will provide us a better understanding of the existing Hepatozoon blood parasite species within gopher tortoises in South Florida.
