Title: Acute toxicity of the agricultural chemicals endosulfan and copper sulfate to a freshwater shrimp, Palaemonetes paludosus.
Creator: Kamthe, Prajakta Netaji, Florida Atlantic University, Baldwin, John D., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The toxicity of endosulfan, a restricted use pesticida, and copper sulfate, an anti-algal agent, ranks among the highest in all insecticidas. Both chemicals, used in agricultura fields of southern Florida, are known to be highly toxic to aquatic invertebrates. Since Palaemonetes pugio, an extensively studied brackish water shrimp species, has proven to be excellent for toxicological analysis, a closely related freshwater shrimp species, Palaemonetes paludosus, was used as the test species in...
Show moreThe toxicity of endosulfan, a restricted use pesticida, and copper sulfate, an anti-algal agent, ranks among the highest in all insecticidas. Both chemicals, used in agricultura fields of southern Florida, are known to be highly toxic to aquatic invertebrates. Since Palaemonetes pugio, an extensively studied brackish water shrimp species, has proven to be excellent for toxicological analysis, a closely related freshwater shrimp species, Palaemonetes paludosus, was used as the test species in this study to determine the toxicity of endosulfan and copper sulfate in freshwater. A series of static renewal 96 h bioassays (renewed every 24 h) performed on juvenile P. paludosus resulted in the 96 h lethal concentration (LC50) estimates of 0.24 mug/L (0.24 ppb) for endosulfan and 0.79 mg/L (0.79 ppm) for copper sulfate. The results of this study, when compared to other studies, indicate that P. paludosus is more sensitive to endosulfan and copper sulfate than other similar aquatic invertebrate species and is therefore an excellent toxicological indicator.

Abstract/Description: This study investigated variations m body condition of brown hoplos (Hoplosternum littorale) refuging in ponds in the Big Cypress region of southern Florida. During the dry season environmental parameters fluctuated, water depth and dissolved oxygen decreased, while temperature and conductivity increased. Standard lengths and wet weights of 675 juvenile brown hoplos were measured from seven populations. Body condition was compared between populations and through time (early vs. late dry...
Show moreThis study investigated variations m body condition of brown hoplos (Hoplosternum littorale) refuging in ponds in the Big Cypress region of southern Florida. During the dry season environmental parameters fluctuated, water depth and dissolved oxygen decreased, while temperature and conductivity increased. Standard lengths and wet weights of 675 juvenile brown hoplos were measured from seven populations. Body condition was compared between populations and through time (early vs. late dry season) using length-weight relationship and Fulton's condition factor. The only significant spatia-temporal variations in body condition occurred in the deepest refuges. One population demonstrated an unexpected positive change in body condition, while another (a deep culvert pond) showed negative changes in body condition over time. Smaller fish (≤S65mmSL) found in these deep-water refuges demonstrated the most change in body condition. Almost all populations exhibited isometric growth but the culvert pond population had variable regression slopes (slopes ≠ 3 for both samples).

Title: Effects of a Disturbance Event on a Local Recreational Fishery on the East Coast of Florida.
Creator: Noble, Jessica, Baldwin, John D., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: Disturbance events occur outside the normal disturbance regime of a system and can cause changes in behavior of some organisms. The 2010 cold event is an example of a disturbance event that influenced the behavior of Common Snook (Centropomus undecimalis). Common snook are euryhaline sportfish native to Florida, Texas, and the Caribbean. Florida is the northern most part of their distribution, based on the 15o C winter isotherm. They move between offshore areas during spawning season and...

The 2010 cold event is an example of a disturbance event that influenced the behavior of Common Snook (Centropomus undecimalis). Common snook are euryhaline sportfish native to Florida, Texas, and the Caribbean. Florida is the northern most part of their distribution, based on the 15o C winter isotherm. They move between offshore areas during spawning season and freshwater coastal rivers during non-spawning season. With the use of previously collected acoustic telemetry and biological data this project identifies the impact on population dynamics and movement near the time of the event. The goal is to understand fine scale movements and physiological conditions under normal and abnormal conditions to further inform management of the species.

Title: Food habits of breeding bald eagles (Haliaeetus Leucocephalus) in Florida Bay, Everglades National Park.
Creator: Hanson, Matthew, Baldwin, John D., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The population of Bald Eagles in Florida Bay, Everglades National Park has declined over the past few decades. It is hypothesized that changes in prey availabilities from alterations to ecosystem conditions have contributed to this decline. Our goals were to document diet and explore how prey availabilities may affect the Bald Eagle. For the 2009 and 2010 breeding seasons we collected prey remains from nest sites and video monitored provisioning of prey. Prey remains consisted of 33 species...

It is hypothesized that changes in prey availabilities from alterations to ecosystem conditions have contributed to this decline. Our goals were to document diet and explore how prey availabilities may affect the Bald Eagle. For the 2009 and 2010 breeding seasons we collected prey remains from nest sites and video monitored provisioning of prey. Prey remains consisted of 33 species and were compositionally different than prey remains collected prior to ecological changes, suggesting changes in prey availabilities. Also, provisioning rates were significantly lower than Bald Eagles in other North American regions and declined throughout the breeding season. Our results suggest that prey availabilities has affected the food habits of breeding Bald Eagles in Florida Bay, which may be contributing to their decline.

Ascanius and C. mitis individuals. Apart from Gombe Stream National Park, there is no of evidence suggestive of C. ascanius x C. mitis monkey hybridization at investigated East African locations. Phylogenetic analysis was examined using Mitochondrial DNA (mtDNA) sequence data of twelve C. mitis stuhlmanni samples (from two populations) in Kibale National Park (KNP), Uganda to test for any evidence of hybridization. Strict mono- phylogeny among two new C. mitis haplotypes were detected. Genetic diversity measurements support neither interspecific or intraspecific hybridization among C. mitis individuals from populations within Kibale National Park. To intensify the implications of this study further examination should include an increase in sample size(s), mtDNA comparison of C. mitis subspecies from additional populations at East African locations, and assessment of nuclear and genomic DNA.

Title: Growth rates and body condition of juvenile green turtles (Chelonia mydas) in Dry Tortugas National Park and Marine Protected Area.
Creator: Reintsma, Nicole, Baldwin, John D., Hart, Kristen, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: Dry Tortugas National Park (DRTO) consists of 261.8 km2 in the Gulf of Mexico and provides protection to marine species facing a multitude of threats. Among the many species that utilize DRTO is the green sea turtle (Chelonia mydas). I examined seven years of capture-recapture data to determine how the body condition (using Fulton’s equation, K = M/L3) and growth rate for juvenile green turtles vary within, and among size classes in DRTO, and how those rates compare to similar populations in...

I examined seven years of capture-recapture data to determine how the body condition (using Fulton’s equation, K = M/L3) and growth rate for juvenile green turtles vary within, and among size classes in DRTO, and how those rates compare to similar populations in other locations. Body conditions ranged from 0.77 to 1.71 (mean 1.3 SD ± 0.16). Growth rates ranged from 2.5 to 9.9cm/yr (mean 5.5 cm/yr SD ± 1.25), which is a high growth rate for green turtles. Establishing growth rates and body condition for a specific population can provide insight into life history and health of that population, as well as important data for comparison to populations in other areas.

Title: Interpreting the Pre-Nesting Foraging Ecology of Florida’s Leatherback Turtles (Dermochelys coriacea).
Creator: Coppenrath, Christina, Baldwin, John D., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The migratory behavior of North Atlantic leatherback turtles (Dermochelys coriacea) has been documented in the Wider Caribbean, but the migratory movements of leatherbacks nesting in South Florida are relatively understudied. Our knowledge of their migrations is currently limited to ten nesting females tracked from the east coast of Florida that either moved north to the Northern Atlantic or east to the coast of Western Africa.

Show moreThe migratory behavior of North Atlantic leatherback turtles (Dermochelys coriacea) has been documented in the Wider Caribbean, but the migratory movements of leatherbacks nesting in South Florida are relatively understudied. Our knowledge of their migrations is currently limited to ten nesting females tracked from the east coast of Florida that either moved north to the Northern Atlantic or east to the coast of Western Africa. These results bring to light the need for further investigation and larger sample sizes to identify and determine the relative importance of the different foraging areas for the leatherbacks nesting in South Florida. Here, I analyzed stable carbon (δ13C) and stable nitrogen (δ15N) values in whole blood and skin of leatherbacks nesting in South Florida between 2014 and 2017 to estimate the putative foraging origins of these nesters prior to coming to South Florida to nest. This study provides some of the first stable isotope inferences and insights into the variable pre-nesting foraging habitat locations of Florida’s leatherback population.

Title: Movement, dispersal and interpreting health assessment parameters for free-ranging raptors and a reptile in a compromised estuarine ecosystem.
Creator: Mealey, Brian K., Baldwin, John D., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: This investigation compared statistical parameters for the blood serum chemistries of free ranging Osprey nestlings from Florida Bay and an Osprey population from Lake Istokpoga, in Central Florida (Chapter 1). Florida Bay Ospreys showed higher mean rank values for alanine aminotransferase (H=6.79, P=.009), alkaline phosphatase (H=6.48, P=.011), and sodium (H=5.7, P=.017), and Central Florida had higher mean rank values potassium (H=13.19, P=.000) and carbon dioxide (H=6.23, P=.013).

Florida Bay Ospreys showed higher mean rank values for alanine aminotransferase (H=6.79, P=.009), alkaline phosphatase (H=6.48, P=.011), and sodium (H=5.7, P=.017), and Central Florida had higher mean rank values potassium (H=13.19, P=.000) and carbon dioxide (H=6.23, P=.013). Serum chemistries values were also compared between free-ranging Bald Eagle and Osprey nestling in Florida Bay estuary in southern Florida (Chapter 2). There were significant differences between serum values of Bald Eagle and Osprey nestlings. Bald Eagle serum values were higher for total protein (H=17.833, P=.00002), Albumin (H=7.449, P=.006), Aspartate aminotransferase (H=113.153, P =.0001), and Calcium (H=7.148, P = 008). Osprey serum values were higher for alanine aminotransferase (H=11.824, P = 0.0005), alkaline phosphatase (H=105.5, P =.0001), creatine kinase (H=13.465, P = 0.0002), carbon dioxide (H=4.443, P = 0.035) and cholinesterase (H=99.3, P=.0001). Sixteen nestling Bald Eagles were fitted with satellite platform transmitter terminal (PTT) or VHF radio transmitter package for a duration of six years (Chapter 3)= to identify their movement and dispersal. One of the 15 eagles migrated to North Carolina, whereas the other 14 (93%) confined their movements to Florida. Tracking duration per individual ranged from 82 to 1,531 days. We estimated first-year survival as 52% and 67% for the period from 1.5 to 3 years. Diamondback Terrapins (Chapter 4) were evaluated by an integrated assessment of physical, chemical, and physiological parameters. Extreme site fidelity of the turtles to mangrove habitat was evident along with a strong female biased sex ratio. There was a significant difference in the total number of individuals collected at the two sites (P =. 01) despite the total size and shorelines of the two sites being very nearly the same. Total recapture rate was 70% for combined population (TLK = 80% and CKW = 48%). We provide blood serum values and microbial cultures as baselines from these turtles in the wild.

Show moreThe wahoo, Acanthocyhium solandri, is a pelagic marine fish which inhabits tropical, subtropical, and warm temperate waters worldwide. Despite being highly mobile and economically important over most of their range, there is little scientific data concerning population structure, movement patterns, or environmental preferences of wahoo. In this study I investigate wahoo genetic population structure and phytogeography on a global scale, and deploy pop-up satellite archival tags (PSA T's) in the western Atlantic Ocean to determine movement patterns and environmental preferences of wahoo. Wahoo population genetic structure was examined across their entire global range with intron six of lactate dehydrogenase-A (ldhA6, 10 locations, N = 213) and mtDNA cytochrome h (Cyth, 13 locations, N = 322). Results show extensive sharing ofhaplotypes and no significant structure between all locations (mtDNA ~ST < 0.0001, P = 0.634; nuclear FsT = 0.0125, P = 0.1 06). Overall nuclear heterozygosity (H = 0.714) and mtDNA haplotype diversity (h = 0.918) are both high, while overall mtDNA nucleotide diversity (n = 0.006) and nuclear nucleotide diversity (n = 0.004) are uniformly low. Coalescence indicates an effective female population size CNeF) at - 816,000, and a population bottleneck - 690,000 years ago. Movement patterns and environmental preferences were investigated by deploying PSA T's onto four individual wahoo in the western Atlantic Ocean. Tagging success rate (75%) validates the deployment protocol developed for this project. Results indicate that wahoo in the western Atlantic ocean spend the greatest portion of their time between 0 and 20 meters of depth, and between temperatures of 20oC and 26°C. More time was spent near the deeper extremes of their range during the nocturnal period, and daily visits to the surface were observed. Wahoo were observed traveling north in Fall and Winter, contrary to previous notions concerning the migratory movements of this species. The genetic results indicate a worldwide stock for wahoo, which reinforces the mandate for international cooperation on fisheries issues. The PSA T results demonstrate the value of the acquired data to the investigation of important life history parameters in pelagic species. The information generated from this project will benefit fisheries managers, marine biologists, evolutionary biologists, and both commercial and recreational fishing interests.
