Abstract/Description

The ecological site at the Boca Raton campus of Florida Atlantic University, a 0.3 𝑘𝑚2 natural preserve site, is an excellent study in the effects of human disturbance at natural sites. A floral inventory was conducted using stratified sampling of macro plots to determine changes in biodiversity, nonnative species ratios, and wetland species ratios compared to a similar 1990 study. It was found that the site was 25.56% less biodiverse and contained 18.47% more nonnative species in the past...

A floral inventory was conducted using stratified sampling of macro plots to determine changes in biodiversity, nonnative species ratios, and wetland species ratios compared to a similar 1990 study. It was found that the site was 25.56% less biodiverse and contained 18.47% more nonnative species in the past thirty years. The percentage of wetland species found decreased 32.80% and upland species have increased by 19.86% in the same time period. These results are consistent with ecological trends found in natural sites in South Florida, a result of human alteration of the land in the past century.

Abstract/Description

Lichens are commonly used as bioindicators of air pollution. For my thesis, I tested the utility of two easily identified lichen species as bioindicators. Parmotrema perforatum is considered to be pollution intolerant, while Parmotrema subrigidium is considered to be somewhat pollution tolerant. I surveyed P. perforatum and P. subrigidum growing on the trunks of southern live oak trees (Quercus virginiana) at two sites on the John D. MacArthur campus of Florida Atlantic University in Jupiter,...

Parmotrema perforatum is considered to be pollution intolerant, while Parmotrema subrigidium is considered to be somewhat pollution tolerant. I surveyed P. perforatum and P. subrigidum growing on the trunks of southern live oak trees (Quercus virginiana) at two sites on the John D. MacArthur campus of Florida Atlantic University in Jupiter, Florida that differed in exposure to road traffic. One site on the interior of campus (AOS1) was distant from any road, while the other site (AOS2) was along a busy road. I identified lichen samples from using keys and chemical spot tests. I found AOS1 had a higher density of P. perforatum, and whereas AOS2 had a higher density of P. subrigidum, confirming the utility of these two lichens as bioindicators of pollution.

I found that most of the plant species I documented, a total of 179 plant species, include 37 native and eight non-native species not previously listed. These eight non-native species are described further in detail on their invasive status and how they made their way into the preserve.

Bats in Florida are commonly seen foraging for insects attracted to artificial lights. For my thesis, I set up ultrasonic recording equipment at highway rest areas under large streetlights in Martin and Palm Beach County to see how frequently different bat species visited each area. I identified a total of 1598 calls, including 159 calls of rare or endangered species. I found most frequently recorded species at both sites was the Brazilian free-tailed bat (Tadarida brasiliensis), a very common species in South Florida. My other findings suggest that the known rarity and range of some species should be reconsidered. The importance of streetlights to the survival of insectivorous bats certainly deserves additional attention.

Malaclemys terrapin is divided into seven subspecies based on geographic location and variations in physical appearance. For my research, I examined the diet of the Florida East Coast Diamondback Terrapins, M. terrapin tequesta, in the Indian River Lagoon near Vero Beach, Florida. I analyzed 13 terrapin fecal samples. Of these, all but one contained the remains of decapod crustaceans, the most common of which was the mangrove tree crab, Aratus pisonii, found in six samples. Bivalve, gastropod, and plant material were also present in several samples. This primarily crustacean diet contrasts with the diets of other M. terrapin subspecies that have ben studied, which fed most commonly on plants, gastropods, and bivalves.

The Florida bonneted bat (Eumops floridanus) is an endangered species found only in southern Florida. There is little ecological information known for this species, making conservation work difficult in protecting it.

There is little ecological information known for this species, making conservation work difficult in protecting it. What we do know, however, is that they are large, insectivorous, high-flying mammals that can travel over vast distances in a single night. With these characteristics it made me wonder if E. floridanus would find baseball stadiums an acceptable hunting ground. They have wide-open spaces, the bright stadium lights attract insects, and the field lights themselves are hundreds of feet high. To test if this is true, I set up ultrasonic recording equipment at Roger Dean Stadium (and two other baseball fields with differing environmental factors) to see if there is a difference in activity between nights when the lights are on or off. With this information about E. floridanus feeding habits, current conservation practices could be improved upon.

I then examine what research has been done to evaluate the effectiveness of the different products and their therapeutic uses.

Abstract/Description

The purpose of this thesis is to highlight the underrepresentation of South Florida in the field of mycology. Upon reviewing samples and comparing them to their closest genetic match, it is safe to conclude that there are a significant number of samples with either unidentified or unknown species. Of the samples observed and recorded, a surprising 17 of 39 or 43.5% have only been identified as far as the Genus. These findings indicate a necessity for further research beyond the Genus to...

Within mathematics, the field of algebra focuses primarily on preserving symmetry and structure within a set. This thesis focuses on a given group G over a (commutative) ring R, referred to as the group ring R[G]. Elements within R[G] are finite formal sums of elements of G with coefficients from R. A class of reduced rings that generalizes integral domains is that of complemented rings. We will discuss new subcategories of complemented rings: semi-complemented and almost complemented rings....

A class of reduced rings that generalizes integral domains is that of complemented rings. We will discuss new subcategories of complemented rings: semi-complemented and almost complemented rings. Since R[G] is a ring itself, we would like to find when R[G] is complemented or perhaps only semi or almost complemented. We will discuss small examples such as Z2[D3] and Zk[Cn].

Marine environmental conditions were maintained in an artificial seawater medium. Induced c1 and ex enzymes and cellobiase were determined colorimetrically. Induction also occurred on cellobiose, but not on glucose and lactose. Permenter studies with glucose and with toilet tissue carbon sources gave close correlations between mycelial dry weight, enzyme component activity, and cell nitrogen. In cotton substrate media, Tween 80 increased C1 activity by 148%, and Cx activity by 160%, on the average. Millipore ultrafiltration was the best technique for concentrating cellulase for Sephadex G-75 column chromatography, while conventional techniques were unsuccessful. Fractionation diagrams for all cultures were similar with 2 distinct peaks. The low molecular weight fraction contained mainly Cx enzyme activity, while the high molecular weight fraction contained C1 and Cx enzymes and cellobiase. These fungi possess a cellulase similar, but not identical, to that found in terrestrial species.

Show moreTheories addressing rights ascription and moral consideration have historically often focused on humans as the singular objects of moral agency. I examine the reasoning behind this focus to discover the degree to which non-human animals and artificial intelligence machines should be considered rational beings deserving of both moral consideration and legal personhood, on-par with a human. The disconnect between the moral consideration and rights ascription bestowed on profoundly-handicapped humans, anomalously-rational non-human animals, and AI machines of similar abilities is representative of anthropocentric speciesism and must be corrected if rational ability is the motivating force behind moral consideration and rights ascription. By removing the group affiliations or classifications of any being, we can create a more dynamic legal rights ascription system that only takes into account the abilities of the individual and their relevance within a given society. This new system serves to more accurately accommodate and represent anomalous beings of any species.

For my thesis work, I attempted to develop a mutant strain of the marine bacteria Photobacterium damselae subsp. damselae capable of sequestering lithium from seawater. I expose the bacteria to shortwave ultra violet (UV) light with the intent of obtaining a lithium dependent mutant. I was not successful at isolating such a mutant. However, I noted differences in colony size, between colonies grown in lithium media and sodium media, after UV treatment. Based on other research, the bacterial recovery methods of lithium and other metals from seawater remains a plausible option.
