Predicting Severe Wildfire Years In The Florida Everglades, Brian Beckage, William J. Platt

Faculty Publications

© 2003 The Ecological Society of America. Wildfires result in important ecological benefits to many ecosystems, but have costs associated with fire fighting and property loss. Accurate, timely forecasts of the severity of upcoming wildfire seasons could facilitate wildfire management, limiting the most destructive aspects of fires, while preserving their ecological benefits. We demonstrate an approach where time series models are used to predict the severity of the wildfire season in Everglades National Park in southern Florida 3 months and 1 year beforehand. Model predictions contained all obserations within a 90% credible interval and also anticipated severe wildfire seasons. These …

Detecting Malfunction In Wireless Sensor Networks, Pablito C. Lake

Theses

The objective of this thesis is to detect malfunctioning sensors in wireless sensor networks. The ability to detect abnormality is critical to the security of any sensor network. However, the ability to detect a faulty wireless sensor is not trivial. Controlled repeatable experiments are difficult in wireless channels. A Redhat Linux. 7.0 Wireless Emulation Dynamic Switch software was used to solve this problem.

Six nodes were configured with a node acting as a base station. The nodes were all part of a cell. This means that every node could communicate with all other nodes. A client-server program simulated the background …

Temporal And Spatial Variability Of Sinking Particles In The Southeast Bering Sea, Stacy Lynn Smith

Marine Biology

The factors affecting the timing, quantity and fate of southeastern Bering Sea primary production, including coupling to higher trophic levels, were investigated via sinking particles collected using sediment traps. Stable carbon and nitrogen isotopic composition and lipid composition of zooplankton and sinking particles were measured for middle (M2) and outer (M3) shelf samples collected during 1997-2000. The quantity collected by the M2 sediment trap was high in late summer and fall, as well as during spring blooms, and was much greater than that collected at M3. M2 zooplankton and trap samples were enriched in ¹⁵N and ¹³C over those from …

Paralytic Shellfish Poisoning: The Relationship Between Alexandrium Abundance And Psp Toxins On Kodiak Island, Alaska, Julie A. Matweyou

Marine Biology

Paralytic shellfish poisoning (PSP) events have severe negative impacts on Alaska commercial shellfish fisheries as well as recreational and subsistence harvests. This study, designed to improve existing PSP monitoring programs, involved the use of a rapid sandwich hybridization assay to detect and quantify the relative abundance of Alexandrium catenella based on species-specific LSU rRNA targeted oligonucleotide probes. Blue mussel (Mytilus edulis) toxicity, expressed as saxitoxin equivalents, was determined using the ³H-Saxitoxin receptor binding assay. Shellfish toxicity was relatively low in both 2000 and 2001 compared to historically high values on Kodiak, but exhibited pronounced late spring and late summer peaks, …

Migrant Stopover Ecology And Resident Resilience After Hurricane Iris In A Neotropical Bird Community, Andrew Bryant Johnson

Biological Sciences

I conducted two avian ecology studies in southern Belize. I examined mass gains by Nearctic-Neotropic migrants in forest near the Gulf of Honduras, a potential ecological barrier to migration. Condition indices (mass/wing chord or tail length) were used to estimate net diel mass gains in migrant species. Ten migrant species apparently were fattening at the site, but some species not fattening at the site had accumulated fat loads elsewhere, and this region appears to provide important resources for transient migrants. I also studied the resilience of a marked resident bird community after Hurricane Iris severely altered the habitat. Given the …

Ecomorphology Of Bats: Comparative And Experimental Approaches Relating Structural Design To Ecology, Sharon M. Swartz, Patricia W. Freeman, Elizabeth F. Stockwell

School of Natural Resources: Faculty Publications

The past several decades have seen the beginning of integration of discoveries in the ecology and morphology of bats into an ecomorphological whole that promises to be greater than the sum of its parts. However, achieving this integration is challenging. Each of the elements of this interdisciplinary field is, in itself, avast and complex subject. This book is a testament to the breadth and depth of ecological studies of bats. Morphological studies now extend be- yond descriptive anatomy in both outlook and method, and incorporate, for example, aspects of genetics, physiology, solid and fluid mechanics, and developmental biology. There is …

Species Pairwise Associations Over Nine Years Of Secondary Succession: Assessing Alternative Explanations And Successional Mechanisms, Lara R. Rozzell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance and mechanisms of species interactions are undetermined in most successional systems. I used correlations and null modeling to detect pairwise species associations between 33 plant species in the first nine years of secondary succession after logging and burning in a western Oregon Cascade forest. I tested for correlations between each species and soil nutrients, nonvegetative ground cover, and surrounding vegetation. More positive than negative associations were found at all sampling times. The proportion of positive associations decreased and negative associations increased through time. Up to 42% of associations at a sampling time were explicable by shared positive correlations …

Optimization Of Single-Base-Pair Mismatch Discrimination In Oligonucleotide Microarrays, Hidetoshi Urakawa, Said El Fantroussi, H Smidt, James C. Smoot, Erik H. Tribou, John J. Kelly, Peter A. Noble, David A. Stahl

Biology: Faculty Publications and Other Works

The discrimination between perfect-match and single-base-pair-mismatched nucleic acid duplexes was investigated by using oligonucleotide DNA microarrays and nonequilibrium dissociation rates (melting profiles). DNA and RNA versions of two synthetic targets corresponding to the 16S rRNA sequences of Staphylococcus epidermidis (38 nucleotides) and Nitrosomonas eutropha (39 nucleotides) were hybridized to perfect-match probes (18-mer and 19-mer) and to a set of probes having all possible single-base-pair mismatches. The melting profiles of all probe-target duplexes were determined in parallel by using an imposed temperature step gradient. We derived an optimum wash temperature for each probe and target by using a simple formula to …

Horned Lark (Eremophila Alpestris L.) Predation On Alkali Bees, Nomia Melanderi Cockerell, Richard W. Rust

Western North American Naturalist

Horned Larks (Eremophila alpestris L.), sampled during the first 2 weeks of alkali bee (Nomia melanderi Cockerell) emergence at bee nesting sites in 2 alfalfa seed-growing regions in central Nevada, ate significantly more male than female alkali bees. Exploitation rates suggest that individual Horned Larks consume 10 to 200 alkali bees per day and feed an additional 300 to 1000 bees per day to nestlings nestlings.

Environmental Characteristics And Benthic Invertebrate Assemblages In Colorado Mountain Lakes, Brenda Moraska Lafrancois, Daren M. Carlisle, Koren R. Nydick, Brett M. Johnson, Jill S. Baron

Western North American Naturalist

Twenty-two high-elevation lakes (>3000 m) in Rocky Mountain National Park and Indian Peaks Wilderness Area, Colorado, were surveyed during summer 1998 to explore relationships among benthic invertebrates, water chemistry (particularly nitrate concentrations), and other environmental variables. Water samples were collected from the deepest portion of each lake and analyzed for ions and other water chemistry parameters. Benthic invertebrates were collected from the littoral zone using both a sweep net and Hess sampler. Physical and geographical measurements were derived from maps. Relationships among benthic invertebrate assemblages and environmental variables were examined using canonical correspondence analysis, and the importance of sampling …

Effects Of Grass Bug Feeding And Drought Stress On Selected Lines Of Crested Wheatgrass, Robert S. Nowak, James D. Hansen, Cheryl L. Nowak

Western North American Naturalist

The sequential effects of feeding by grass bugs (Irbisia pacifica [Hemiptera: Miridae]) and of drought stress on the growth of 2 crested wheatgrasses (the hybrid Agropyron cristatum × desertorum and A. cristatum cv. 'Fairway') were investigated in a controlled greenhouse experiment. Growth rates of genotypes that were previously selected for resistance to grass bug feeding were not consistently greater than those of unselected genotypes when plants were exposed to bug feeding. Thus, the mechanism of resistance to bug feeding for the selected genotypes does not appear to be "tolerance," i.e., rapid growth rates that allow the resistant genotypes to …

The Treeline Ecotone In Interior Alaska: From Theory To Planning And The Ecology In Between, Martin Wilmking

Forest Sciences

Treelines have been the focus of intense research for nearly a hundred years, also because they represent one of the most visible boundaries between two ecological systems. In recent years however, treelines have been studied, because changes in forest ecosystems due to global change, e.g. treeline movement, are expected to manifest first in these areas. This dissertation focuses on the elevational and latitudinal treelines bordering the boreal forest of interior Alaska. After development of a conceptional model of ecotones as three-dimensional spaces between ecosystems, we offer a historical perspective on treeline research and its broader impact in the Brooks Range, …

Population Structure Of The Gopher Tortise (Gopherus Polyphemus) In Florida, Using Microsatellites, Tonia S. Schwartz

USF Tampa Graduate Theses and Dissertations

Gopher tortoise (Gopherus polyphemus) population sizes have drastically declined in the past 100 years. Much of this decline has been attributed to past human predation, to habitat loss from human development, and potentially to the recently discovered upper respiratory tract disease. An understanding of the genetic structure among populations is critical for the long-term success of relocation and other management strategies. This research focuses on the development of a suite of genetic markers and the answers they provided to questions concerning present day population genetics and its use in management. In addition, this study provides inference on historical …

The Ecology Of New World Rodent Borne Hemorrhagic Fevers, Darin S. Carroll, Emily Jentes, James N. Mills

Wildlife Damage Management Conference

Few, if any, human settlements are free of peridomestic rodent populations. The threat of rodent borne zoonotic diseases has been widely recognized since the bubonic plague outbreaks of the Middle Ages. In the last decades, outbreaks of human disease caused by the rodent borne hemorrhagic fever viruses, the arenaviruses (family Arenaviridae), and the hantaviruses (family Bunyaviridae, genus Hantavirus) have again generated interest in the general public and scientific community regarding the biology of these types of diseases. Recent studies have identified more than 30 new members of these two groups of viruses. Most are associated with rodents in the family …

The Bold And The Shy: Individual Differences In Rainbow Trout, L. U. Sneddon

Aquaculture Collection

Boldness and shyness were investigated as ‘personality’ traits in hatchery-reared rainbow trout Oncorhynchus mykiss. Bold fish spent more time in an open area and were more active than shy fish and these behaviours could be used as indicators of boldness and shyness. These differences were related to learning ability in a simple conditioning task. Bold fish learned the task more quickly than shy fish.

Direct Profiling Of Environmental Microbial Populations By Thermal Dissociation Analysis Of Native Rrnas Hybridized To Oligonucleotide Microarrays, Said El Fantroussi, Hidetoshi Urakawa, Anne E. Bernhard, John J. Kelly, Peter A. Noble, H Smidt, G M. Yershov, David A. Stahl

Biology: Faculty Publications and Other Works

Oligonucleotide microarrays were used to profile directly extracted rRNA from environmental microbial populations without PCR amplification. In our initial inspection of two distinct estuarine study sites, the hybridization patterns were reproducible and varied between estuarine sediments of differing salinities. The determination of a thermal dissociation curve (i.e., melting profile) for each probe-target duplex provided information on hybridization specificity, which is essential for confirming adequate discrimination between target and nontarget sequences.
