Title: Preliminary Census of Free Ranging Vervet Monkeys, Chlorocebus sabaeus,in Dania Beach, Forida.
Creator: Williams, Deborah, Broemel, Erin T., Graduate College, Detwiler, Kate M.
Abstract/Description: Observations of vervet monkeys, Chlorocebus sabaeus, have been documented in 3700 hectares of mangrove preserves of Dania Beach, Florida since the 1950’s. A scientific census in 1995 provided confirmation of this population. Endemic to West Africa, research suggests this primate has adapted to the ecology of the mangrove environment in Southeast Florida. The 1995 census showed the population consisted of two groups with a total of 36 individuals. We resurveyed the population from January...
Show moreObservations of vervet monkeys, Chlorocebus sabaeus, have been documented in 3700 hectares of mangrove preserves of Dania Beach, Florida since the 1950’s. A scientific census in 1995 provided confirmation of this population. Endemic to West Africa, research suggests this primate has adapted to the ecology of the mangrove environment in Southeast Florida. The 1995 census showed the population consisted of two groups with a total of 36 individuals. We resurveyed the population from January-February 2014 by visiting sites where monkeys have been reported either in the media or by local residents. We found the vervets inhabit two geographically isolated areas, separated by a man-made waterway. The population is divided into three groups with a total of 18 individuals. Group A, which occupies the northern most part of the mangroves consists of 3 adult males, 1 juvenile male, 5 adult females, and 1 infant. Group B, which occupies the central part of the mangroves consists of 1 adult male, 2 adult females, 1 sub-adult female, and 2 juveniles. Group C, which occupies the southern part of the mangroves consists of 2 adult females. In the 1995 study, this southern group ranged in size from 19-23 individuals. Our results indicate the total population decreased significantly in size over the past 19 years. To confirm this population decrease, research will expand surveys into unexplored areas of the mangrove preserve to document the presence or absence of additional groups. Ongoing research will investigate day ranges, behavior, and feeding ecology of this feral primate population.

Title: Human/Non-Human Primate Interface in Dania Beach, Florida.
Creator: Broemel, Erin T., Williams, Deborah, Graduate College, Detwiler, Kate M.
Abstract/Description: The frequency of interactions between humans and non-human primates has risen in past decades due to the loss of primate habitat. Many primates now live within human habitats, raising questions about how humans interact with and affect primates. Dania Beach, Florida provides an unusual opportunity to study the dynamics of human interactions with a population of introduced primates.

Show moreThe frequency of interactions between humans and non-human primates has risen in past decades due to the loss of primate habitat. Many primates now live within human habitats, raising questions about how humans interact with and affect primates. Dania Beach, Florida provides an unusual opportunity to study the dynamics of human interactions with a population of introduced primates. We examined the effect of human behavior on three groups of green vervet monkeys, Chlorocebus sabaeus, through behavioral observations conducted from January-February 2014. North Group A, located on business property, is provisioned 3x daily with nutrient dense fruits and nuts. These monkeys are habituated to human presence and appear to benefit from positive interactions with humans. North Group B, located within mangrove forest near businesses, is provisioned 2x daily with fruits, and restaurant food 2x weekly. This group is less habituated than North Group A, and avoids human contact outside of provisioning. In contrast, South Group C is situated within a residential area and has a history of being trapped since 1993. They are minimally provisioned, and rely on human food items from trash. South Group C exhibits defensive and aggressive behaviors towards humans. These results suggest that primates living in this group experience a negative human relationship, which may lead to an increase in stress levels. Additional exploration into the Dania Beach human/non-human primate interface is required to better understand the potential link between negative human interactions and primate proximity to residential areas.

Title: A camera trap study of the cryptic, terrestrial guenon Cercopithecus lomamiensis in central Democratic Republic of Congo.
Creator: McPhee, Steven G., Ayali, Pablo, Graduate College, Hart, John A., Detwiler, Kate M.
Abstract/Description: From October-December 2013, we conducted a camera trap study of the newly discovered primate species lesula, Cercopithecus lomamiensis, in the Lomami River Basin, DR Congo. The primary aim of the study was to examine how lesula fares in the presence of uncontrolled bushmeat hunting. We placed 41 camera traps inside a 4-km2 grid located in the Yawende community conservation area outside the proposed Lomami National Park LNP.

The primary aim of the study was to examine how lesula fares in the presence of uncontrolled bushmeat hunting. We placed 41 camera traps inside a 4-km2 grid located in the Yawende community conservation area outside the proposed Lomami National Park LNP. We compared an analysis of 72 lesula events over 842 camera trap days from the heavily hunted Yawende site to a pilot camera trap study 38 lesula events over 462 camera trap days at the Losekola study site within the LNP. Our data show an unexpected result: capture probability of lesula 0.08 is the same at both the hunted and non-hunted sites. This is in contrast to the sharp decline in capture probability of all other medium to large terrestrial mammals at the Yawende site. These findings suggest lesula’s cryptic behavior is an important adaptation buffering the species from the impact of hunting. However, hunting pressure on lesula may increase in the near future as hunters adjust effort in response to the decline of less cryptic prey species. Our study also expands knowledge on lesula’s diet, group composition, minimum group size, phenotypic traits, and home range. These findings represent the first new data on lesula since its discovery.

The objectives of my study were to expand knowledge on the behavioral ecology of lesula and evaluate lesula’s sensitivity to hunting threats. The main findings from my study included: confirmation of terrestriality and diurnality, births clustering during the wet season, social group living of one male and multiple females, and high impact of hunting on group size. By studying the latest added species to the Cercopithecini tribe, my thesis helps to better understand the ecological diversity occurring within this radiation of African primates and contributes to the species’ long-term conservation efforts.

Show moreNonnative species are reshaping global ecosystems. The success of a nonnative species hinges on both biological and cultural variables. Primates represent a minority of nonnative species but warrant research to understand ecological implications and management solutions. The Florida Fish and Wildlife Conservation Commission recognizes three species of nonnative primates in Florida that include populations of rhesus macaques (Macaca mulatta) in Marion County, squirrel monkeys (Saimiri spp.) in Broward County, and green monkeys (Chlorocebus sabaeus) in Broward County. This study focused on the Dania Beach C. sabaeus population. The goals of this study were to: 1) determine the geographical origins and species of the monkeys, 2) record demographics and determine population growth rate, 3) assess the public’s perception of monkeys, and 4) understand the influence of human provisioning on the population’s behavior and biology. Public surveys and direct field observations of social groups provided baseline data to show that unlike other introduced primates (e.g., macaques in Marion County and green monkeys in the Caribbean), the Dania Beach monkey population has strong public support and is at risk of extinction within the next 100 years.

This study represents the first genetic survey of C. mitis from well provenanced wild populations, including C. mitis heymansi from the TL2 landscape, an area of remote tropical forest between the Tshuapa, Lomami, and Lualaba rivers in the Democratic Republic of the Congo. Tissue samples were collected from 7 male blue monkeys, DNA was extracted and surveyed at 919 bp of the Testis-Specific Protein Y-chromosome (TSPY), and added to a larger dataset including other C. mitis and C. albogularis specimens. Evolutionary analyses suggests TL2 C. mitis shared recent genetic contact with C. albogularis at the headwaters of the Congo River than with conspecifics to the northeast, indicating the Congo River is a significant biogeographic barrier to C. mitis and sheds new light on their genetic heritage, taxonomic assignment, and conservation status.

I scored seven pelage character states as 0 (C. mitis), 0.25 (mitis-like), 0.50 (intermediate), 0.75 (ascanius-like), or 1 (C. ascanius). Photos indicate most phenotypic hybrids express a white nose spot, but all other regions of pelage color and pattern are variable, and an assortment of hybrid phenotypes are seen at Gombe. Results indicate it is currently not possible to extend parameters for assessing color objectively with RGB values, but numerical non-RGB methods show promise.

A total of 63 plant species were identified in our group’s diet. Results indicate that a significant difference exists between the diets of each phenotype. The results also found an unusually high percentage of invertebrate eating (54%) in our group. These findings suggest that invertebrates are an important food resource for the Gombe study group and may help facilitate coexistence in an environment where there are many sympatric primate species.

The objectives were to test the phylogenetic pattern found in the mtDNA tree using a larger sample size of C. m. heymansi, determine the genetic diversity of the population, and hypothesize methods of speciation. While many species within the C. mitis radiation depict paraphyly, I determined that C. m. heymansi forms highly supported monophyletic clades in both mtDNA and Ychromosome gene trees. These results suggest that C. m. heymansi is a distinct lineage within the C. mitis radiation. Future genomic analyses are important in resolving the evolutionary history of this population and discerning its taxonomic classification and conservation value.

Samples were then examined for the presence of gastrointestinal parasites using chlorazol black stain, Lugol’s iodine staining, as well as concentration via fecal flotation with Sheather’s sugar solution. Results were analyzed using SPSS (IBM corp), and compared to other forested regions in Africa to determine whether hybridization influences parasite prevalence of these guenons living in Gombe; and if these guenons differ from similar guenons in other regions of Africa. The null hypothesis was unable to be rejected in all cases; hybridization could not be stated as a contributing factor for differences found in parasitic prevalence rates. Furthermore, no statistical difference was found between Gombe’s guenons, and those living in other regions of Africa in most cases. The author suspects that the abundance of parasitic generalists discovered, small sample size, and opportunistic sampling protocol contribute to these finding.

Show morePersonality is defined as inter-individual variation of behavioral traits while maintaining intra-individual stability. The focus of this study was to observe distinct personality trait categories, establish baseline personality trait phenotypes for the juvenile population, and compare the personality phenotypes between different categories, such as sex or generation. Three personality traits were studied—sociability, curiousity, and boldness—based on the percentage of time individuals spent with conspecifics, human researchers, and their mothers, respectively. The surveyed individuals significantly varied positively and negatively from the means of each trait, and no significant difference for any trait was found between males and females, or across time periods. A moderately strong correlation was discovered between two personality traits, boldness and curiousity, suggesting a personality syndrome. The second primary goal was to use the aforementioned baseline to determine if personality traits can be used to predict neophilic behavior specific to human-dolphin communication research. Six of the study subjects were more prone than their peers to engage with the two-way work, and these individuals were more bold—spent less time with their mothers—than the other subjects. This suggests that boldness has some predictive capabilities towards this type of neophilia.

Remote sensing techniques were utilized to examine land use change over time, create a land classification map, and create a canopy model. These data were used to better understand the area of occurrence of an introduced primate species by examining anthropogenic changes through time and measuring changes in available forest habitat. Corridors, and their transformation through the decades, were evaluated to better understand potential dispersal routes and connectivity to natural areas for colonization.

The analysis includes a look at the average stature of both populations through the use of estimation formulas, as well as taking note of any features on long bones that could denote the possible presence of injury or nutritional maladies which could be indications of social hardships. It also includes a close look at dentition for the presence of possible nutritional deficiencies such as enamel hypoplasias, as well as an analysis to corroborate findings made in initial reports regarding the cataloging of the remains, particularly in the areas of MNI and ancestry. Such analysis can hopefully bring further insight into the lifestyles of those that occupied Florida before contact.

Show moreBioinformatics tools applied to large-scale genomic datasets have helped develop our understanding of primate phylogenetics. However, it is becoming increasingly evident that biological data are accumulating faster than the current capacity of the bioanthropological community to analyze, integrate, and mine the data. Subsequently, this affects how anthropologists create and distribute knowledge. There is a growing need for more training in bioinformatics within anthropological spaces and the development of user-friendly bioinformatic tools for analysis, mining, and modeling of both local and global datasets. This thesis showcases the use of (applied) bioinformatics tools to construct seven new whole mitochondrial genomes to study primate variation. Furthermore, this thesis entails an investigation of the guenon radiation to develop and document bioinformatics and statistical tools to perform a phylogenetic analysis of the genus Cercopithecus. Finally, the utility of the pipelines for other researchers in the Detwiler Lab Group and the potential for further phylogenetic studies are discussed.

Creator: Alempijevic, Daniel, Detwiler, Kate M., Florida Atlantic University, Department of Anthropology, Dorothy F. Schmidt College of Arts and Letters
Abstract/Description: The dryas monkey Chlorocebus dryas, is one of Africa's most enigmatic primates. It was found in the buffer zone of the Lomami National Park (LNP) in 2014, approximately 400 km from its known range. This new record initiated much needed field research on the species’ distribution, habitat preference, behavior, and the validity of the conspecific Cercopithecus salongo. In Chapter 2, we used local knowledge to select sites for a camera trap survey to determine habitat use and relative abundance...
Show moreThe dryas monkey Chlorocebus dryas, is one of Africa's most enigmatic primates. It was found in the buffer zone of the Lomami National Park (LNP) in 2014, approximately 400 km from its known range. This new record initiated much needed field research on the species’ distribution, habitat preference, behavior, and the validity of the conspecific Cercopithecus salongo. In Chapter 2, we used local knowledge to select sites for a camera trap survey to determine habitat use and relative abundance and tested the hypothesis that dryas monkeys are more abundant in the protected LNP than in the buffer zone. Dryas monkeys were detected most frequently in the buffer zone and less in the park, thus we rejected our hypothesis. In Chapter 3, we conducted a survey using a species-specific method to accumulate videos of C. dryas. We used these videos to determine if C. dryas and C. salongo are synonymous. Camera traps revealed an ontogenetic change in pelage pattern that supports the hypothesis that C. salongo is the adult of C. dryas. In Chapter 4, we investigated new occurrences of dryas monkeys in gallery forests in the southern LNP. We tested the hypothesis that dryas monkeys prefer the forest-prairie ecotone over continuous rainforest using occupancy models. Despite considerable effort, only one adult male was detected. Estimated dryas monkey occupancy was 45-91 % in continuous forest and 0-7 % in gallery forest.

Title: MITOCHONDRIAL GENETIC DIVERSITY OF THE RED-TAILED MONKEY, CERCOPITHECUS ASCANIUS, IN AFRICAN RAINFORESTS.
Creator: Dutra, Vitor Daniel, Detwiler, Kate M., Florida Atlantic University, Department of Biological Sciences, Charles E. Schmidt College of Science
Abstract/Description: Cercopithecus ascanius is an African primate species encompassing five geographic types with unresolved taxonomy. Recent publications have analyzed C. ascanius genetic diversity and taxonomy; however, few publications have addressed the genetic diversity and phylogenetic relationships of C. ascanius from wild populations. My objectives for this thesis were to determine mtDNA diversity within the C. Ascanius species and investigate C. ascanius genetic structure. Results from this thesis...
Show moreCercopithecus ascanius is an African primate species encompassing five geographic types with unresolved taxonomy. Recent publications have analyzed C. ascanius genetic diversity and taxonomy; however, few publications have addressed the genetic diversity and phylogenetic relationships of C. ascanius from wild populations. My objectives for this thesis were to determine mtDNA diversity within the C. Ascanius species and investigate C. ascanius genetic structure. Results from this thesis support findings from previous studies wherein C. ascanius depicted high mitochondrial diversity and all C. ascanius subspecies form a monophyletic clade within the Cercopithecus genus. Analyzing additional samples of C. ascanius monkeys will strengthen molecular diversity estimation and clarify genetic structure within the C. ascanius lineage.

Title: Lesula: A New Species of Cercopithecus Monkey Endemic to the Democratic Republic of Congo and Implications for Conservation of Congo’s Central Basin.
Creator: Hart, John A., Detwiler, Kate M., Gilbert, Christopher C., Burrell, Andrew S., Fuller, James L., Emetshu, Maurice, Hart, Terese B., Vosper, Ashley, Sargis, Eric J., Tosi, Anthony J., Turvey, Samuel T.
Abstract/Description: In June 2007, a previously undescribed monkey known locally as ‘‘lesula’’ was found in the forests of the middle Lomami Basin in central Democratic Republic of Congo (DRC). We describe this new species as Cercopithecus lomamiensis sp. nov., and provide data on its distribution, morphology, genetics, ecology and behavior. C. lomamiensis is restricted to the lowland rain forests of central DRC between the middle Lomami and the upper Tshuapa Rivers. Morphological and molecular data confirm that...
Show moreIn June 2007, a previously undescribed monkey known locally as ‘‘lesula’’ was found in the forests of the middle Lomami Basin in central Democratic Republic of Congo (DRC). We describe this new species as Cercopithecus lomamiensis sp. nov., and provide data on its distribution, morphology, genetics, ecology and behavior. C. lomamiensis is restricted to the lowland rain forests of central DRC between the middle Lomami and the upper Tshuapa Rivers. Morphological and molecular data confirm that C. lomamiensis is distinct from its nearest congener, C. hamlyni, from which it is separated geographically by both the Congo (Lualaba) and the Lomami Rivers. C. lomamiensis, like C. hamlyni, is semi-terrestrial with a diet containing terrestrial herbaceous vegetation. The discovery of C. lomamiensis highlights the biogeographic significance and importance for conservation of central Congo’s interfluvial TL2 region, defined from the upper Tshuapa River through the Lomami Basin to the Congo (Lualaba) River. The TL2 region has been found to contain a high diversity of anthropoid primates including three forms, in addition to C. lomamiensis, that are endemic to the area. We recommend the common name, lesula, for this new species, as it is the vernacular name used over most of its known range.
