A previously undescribed skin abnormality, which we refer to as “tiger stripes,” has been identified in Indian River Lagoon bottlenose dolphins through photo-identification surveys. The condition presents as parallel stripes on the ventral and lateral aspects on the torso of the dolphin with varying length and depth. The condition may be indicative of rapid weight loss, similar to human "stretch marks”, debilitating illnesses resulting in emaciation or a result of starvation due to lack of...
Show moreA previously undescribed skin abnormality, which we refer to as “tiger stripes,” has been identified in Indian River Lagoon bottlenose dolphins through photo-identification surveys. The condition presents as parallel stripes on the ventral and lateral aspects on the torso of the dolphin with varying length and depth. The condition may be indicative of rapid weight loss, similar to human "stretch marks”, debilitating illnesses resulting in emaciation or a result of starvation due to lack of prey. Goals of this study were to determine if tiger stripes are: (1) a marker of rapid weight loss, (2) more prevalent in post-partum females, and to (3) examine the spatial and temporal distribution in the IRL. Preliminary findings indicate that tiger striping is a useful marker suggestive of rapid weight loss. The next phase of research is to determine if the condition can be utilized as a pre-mortem marker of emaciation in IRL dolphins.

Recent work on fluorescent α-amino acids (FlAAs) proved extremely useful in studying protein folding, conformational changes and reactivity. When fluorescent tags are appropriately attached to proteins they allow for the detection of their environment and changes therein. Research on the topic of site-specific fluorescent molecules is in its early stages. Several challenges face the topic of selectively excitable fluorescent probes. These include limits on the size and lifetime of synthesized proteins and enzymes, attaching the tag at the target location on a peptide chain which will take advantage of the photochemical properties of the tag, and developing molecules that will readily exhibit environment-sensitive fluorescence.

I evaluated college students using a scanning bed and calipers to determine digit ratio. I then measured calf-circumference, MM using bioimpedence technology and MS using a dynamometer for grip strength.

Show moreFrom 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. 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.

Show moreUnderstanding people through the foods eaten has proven a formidable method to uncover subsistence patterns and infer lifestyle of the earliest inhabitants of an area. With previously examined paleodiet from East Okeechobee Area, Tatham Mound, and Fort Center, particular areas of Florida’s prehistory have begun to resurrect thorough the eye of the scientist. When we understand the foods consumed, we also corroborate that with the environment where the individual resided. Reconstructing foods eaten not only helps researchers understand the ecology of the habitat, but also the social structure of the group the person belonged to. The conglomeration of these factors enables investigators to understand the people, culture, and environment of a region when photographs and written records are unavailable and unaccountable. Using the stable isotopes of carbon, nitrogen, and oxygen, a molecular analysis of the collagen and apatite of bones and tooth enamel signifies the quantities and qualities of proteins and carbohydrates eaten by an individual. This method will be utilized and highlighted in the paleodietary analysis of two sites from the inland zone of southeastern Florida. Two South Florida archaeological sites were discovered housing human remains in the early 1970s. Markham Park and Lauderhill Mound are the two sites used for this analysis. Because of the pottery sherds associated in chronological stratigraphic layers, the date range for each site has been shown to differ by about 500 years. This is significant to assess if the diet compares or contrasts throughout the different time periods.

Conotoxins are promising drugs leads with great prospects in the treatment of diseases and disorders such as chronic pain, multiple sclerosis and Parkinson’s and Alzheimer’s diseases. Similar compounds can be found in plants; for example, cyclotides, which are cyclic peptides isolated from the Violaceae violet, Rubiaceae coffee, and Cucurbitaceae cucurbit families and they have a wide range of biological activities, such as anti-HIV, uterotonic, and antimicrobial. Cyclotides have a cyclic cysteine knot motif characterized by a cyclic backbone and six conserved cysteine residues that form the three disulfide bridges of the “knot”. This motif provides cyclotides with superior stability against thermal, chemical, and enzymatic degradation; marking them as potential frameworks for peptide drug delivery. Cysteine framework IX conotoxins C-C-C-CXC-C, isolated from the venom of Conus brunneus, contain the same cysteine framework, homologous sequences, and similar 3D structures to cyclotides. Presented are details on the isolation of these conotoxins and cyclotides, from Viola tricolor, and the characterization of their activity in the Drosophila melanogaster Giant Fiber System GFS, which contains GAP, acetylcholine, and glutamate synapses.

Show moreThe Big Five inventory is a 44-item scale that classifies participants based on five dimensions of personality with versions available in English and Spanish. Previous studies have found differences in BFI dimensions of Spanish-English bilinguals. We asked if Spanish-English bilinguals described themselves differently when answering in different languages. The present study investigated how Spanish-English bilinguals are classified when answering the BFI in both languages. In a cross-linguistic design, we assessed a sample of Spanish-English bilinguals. We hypothesized that we would find that bilinguals would score significantly different in both languages in the dimensions of extraversion and conscientiousness, with English scores being expected to be significantly higher than Spanish scores. Results revealed significantly different scores in Spanish and English in all five dimensions of the BFI. These results emphasize the issue of language in psychological evaluations, with the possibility of language dependence skewing the results for bilingual patients.

Show moreIn a study conducted by the World Health Organization WHO and United Nations Children’s Fund UNICEF, approximately 768 million people worldwide are not receiving sanitary drinking water suitable for consumption. The greatest levels of water contamination are within the less developed countries where individuals are unable to afford modern water treatment facilities. While there are many water treatment methods, lime softening proves to be one of the more effective approaches as it removes calcium, magnesium, arsenic, barium, beryllium, chromium, cooper, fluoride, lead, mercury, cadmium, nickel, uranium, radium, and radionuclides under the correct conditions. The US Environmental Protection Agency EPA has even defined lime softening as the best available technology BAT for removing uranium and radium. The issue with lime softening is that it is typically used for larger systems that serve whole communities. This project utilizes previous knowledge of lime softening to design a cost-efficient water clarification system with the ability to function on an individual-household basis while being powered by a solar unit. By condensing the system, we hope to make lime softening technology available for a wider spectrum of societies and expend the applications of lime softening.

As a consequence, there is increasing interest in understanding its life history. One difficulty encountered in studying P. maculata is that it lays large, multilayered clutches of very small eggs that are impossible to count without disaggregating the egg mass; which results in the loss of viability. Using a previously described dis-aggregation technique, we weighed, dis-aggregated, photographed, and counted 70 egg masses of P. maculata collected from various locations in Lake Okeechobee. Using the resulting mass and egg numbers we developed an algorithm that reliably relates clutch mass to the number of eggs in a clutch, allowing the estimation of the number of eggs in a clutch without impacting the eggs’ viability and paving the way for investigations into studies on fecundity, hatching rate, etc.

A misuse pattern describes how a misuse is performed from the point of view of the attacker. It defines the environment where the attack is performed, countermeasures to stop it, and provides forensic information in order to trace the attack once it happens.

Results can be obtained within 24 - 48 hrs with very little effort. This semester, we repeated the test and validated the weighting of various parameters. The ITZ assay yield consistent and reproducible data on zones of inhibition of bacteria community. The diameter of inhibition zones was the most important parameter distinguishing resistomes of varying ARI. Landfill, manured garden, and waste plant samples scored highest in antibiotic resistance index compared to beach sand.

Show moreFriendships are important for adolescent adjustment and development; however, adolescent friendships are fleeting. Friend dissimilarity and undesirable individual attributes have been hypothesized to predict friendship dissolution. The present study tests each as predictors of adolescent friendship dissolution. A sample of 410 U.S. adolescents participated in a total of 573 reciprocated friendships originating in the 7th grade. These friendships were followed annually from 8th-12th grade to determine when each friendship dissolved. In the 7th grade, participants completed a peernomination inventory, and teachers completed a survey of each participant’s school competence. Discrete-time survival analyses used 7th grade friend dissimilarity and individual characteristics of sex, age, ethnicity, number of friends, peer acceptance, peer rejection, leadership, physical aggression, relational aggression, peer victimization, and school competence as predictors of the occurrence and timing of friendship dissolution. Friendships originating in the 7th grade were at greatest risk for dissolution during the first year. Only 1 percent of friendships that started in the 7th grade lasted 5 years. Friend dissimilarity on sex, peer acceptance, physical aggression, and school competence predicted friendship dissolution. At each grade, the odds of friendship dissolution were higher for friends dissimilar on these characteristics. Individual characteristics failed to predict friendship dissolution. The findings suggest compatibility is a function of similarity between friends rather than the presence or absence of a specific individual trait. Adolescents seeking friendships with individuals dissimilar from them on school-related characteristics risk suffering the downside of dissimilarity, namely rapid friendship dissolution.
