Adapting A Floral Biogeography Model To Prairie-Dependent Lepidoptera, Eric H. Metzler, John A. Shuey, Leslie A. Ferge, Richard A, Henderson, Paul Z. Goldstein

Proceedings of the North American Prairie Conferences

Analysis of data collected for a study of prairie dependent Lepidoptera in the northern tallgrass prairies showed four distributional patterns. A logical distributional pattern links species' distribution, i.e. Catocala abbreviatella, to larval host plants. Absence of larval host plant data, which is the case for most species of moths, requires inference based on habitat data of known specimens, i.e. Tarachidia binocula, or in the case of infrequently encountered species, i.e. Crambus murellus, capture data for a limited number of specimens. A fourth distributional pattern, i. e. Atrytone arogos, can be explained by hypotheses which explain the …

Seed Mass And Morphology In Outcrossing And Selfing Species Of Clarkia (Onagraceae): An Sem Study, Jennifer L. Knies, Veronique A. Delesalle, A. R. Cavaliere

Biology Faculty Publications

Seeds from three pairs of outcrossing-selfing sister taxa from the genus Clarkia (farewell-to-spring, Onagraceae)—Clarkia unguiculata, Clarkia exilis, Clarkia xantiana ssp. xantiana and ssp. parviflora, and Clarkia concinna ssp. concinna and ssp. automixa—were studied to assess the effects of contrasting mating systems on seed mass and seed morphology. For each outcrossing-selfing comparison, the seed mass of the selfing taxon was less than that of the outcrossing taxon. Seed mass typically differed significantly among populations within a taxon. Scanning electron microscopy showed that the seeds from all these taxa share several characteristics: a bullet to shield shape, a reticulate exotesta pattern, presence …

Diel Activity Patterns, Space Utilization, Seasonal Distribution And Population Structure Of The Yellow Stingray, Urobatis Jamaicensis (Cuvier, 1817) In South Florida With Comments On Reproduction., Daniel P. Fahy

HCNSO Student Theses and Dissertations

The yellow stingray, Urobatis jamaicensis is the most common elasmobranch in the coastal waters of Southeast Florida. Despite their common occurrence the ecology of yellow stingrays remains poorly understood. In particular, yellow stingray daily movements, space utilization, seasonal distribution and population structure have not been described. This study was conducted to address the lack of knowledge of these fundamental life history parameters and to provide further information on the ecology of U. jamaicensis in coastal waters of Broward County, Florida.

The activity patterns and space utilization of U. jamaicensis were assessed by manual tracking with ultrasonic telemetry. Telemetry tracking of …

An Investigation Of Genetic Variation Within Northwest Atlantic Porphyra (Bangiales, Rhodophyta) With Specific Phylogeographic Analysis Of The Common, Rocky Intertidal Species, Porphyra Umbilicalis, Brian William Teasdale

Doctoral Dissertations

To investigate the phylogeography of the rocky intertidal red alga, Porphyra umbilicalis Kutzing, a restriction fragment polymorphism assay (RFLP) of the ribulose bisphosphate carboxylase large subunit ( rbcL) was developed to accurately distinguish P. umbilicalis from the other morphologically similar species in the North Atlantic. Initial screening of ∼800 Porphyra specimens resulted in the additional discovery of a cryptic Porphyra taxon.

The presence and variability of group-I introns of the ribosomal small subunit (SSU) were screened in North Atlantic species of Porphyra in order to assess whether they could be biogeographically informative. In an initial screening for the helix 50 …

Effects Of Silvicultural Practices On Soil Carbon And Nitrogen In A Nitrogen Saturated Central Appalachian (Usa) Hardwood Forest Ecosystem, Frank S. Gilliam, David A. Dick, Michelle L. Kerr, Mary Beth Adams

Biological Sciences Faculty Research

Silvicultural treatments represent disturbances to forest ecosystems often resulting in transient increases in net nitrification and leaching of nitrate and base cations from the soil. Response of soil carbon (C) is more complex, decreasing from enhanced soil respiration and increasing from enhanced postharvest inputs of detritus. Because nitrogen (N) saturation can have similar effects on cation mobility, timber harvesting in N-saturated forests may contribute to a decline in both soil C and base cation fertility, decreasing tree growth. Although studies have addressed effects of either forest harvesting or N saturation separately, few data exist on their combined effects. Our study …

Spatial Patterns Of Estuarine Habitat Type Use And Temporal Patterns In Abundance Of Juvenile Permit, Trachinotus Falcatus, In Charlotte Harbor, Florida, Aaron J. Adams, David A. Blewett

Gulf and Caribbean Research

The life history of many marine fishes is a 2-phase cycle: juveniles and adults make up a demersal phase, whereas larvae are planktonic. Determining ontogenetic patterns of habitat type use of the demersal phase has important management and habitat conservation implications for species that use coastal habitat types as juveniles. Juvenile permit, Trachinotus falcatus, are presumed to be limited to beaches exposed to open ocean, but few studies have addressed juvenile permit use of estuarine habitat types. Ten years of fisheries-independent monitoring data from a subtropical estuary were analyzed to determine habitat type use patterns and seasonality of juvenile …

Mediterranean Landscape Archaeology Past And Present, Effie F. Athanassopoulos, Luann Wandsnider

Department of Anthropology: Faculty Publications

Recent studies of Mediterranean landscapes have emphasized their diversity, their fragmentation, and the high degree of contact between their diverse areas, that is, their connectivity (Horden and Purcell 2000). Moreover, the Mediterranean landscape record is recognized for its length and richness and the opportunity it offers to study long-term interaction between humans and their landscape, however landscape is defined. At the same time, the particular histories of archaeological perspectives that have dominated fieldwork in the region make it difficult to compare with other areas, for example, the New World. Thus, with this volume, our intent is to address issues of …

Developing Integrated Object-Oriented Conception Of Geomarketing As A Tool For Promotion Of Regional Sustainable Development: The Case Study Of Ukraine, Volodymyr M. Anderson

Regional Research Institute Working Papers

In the paper we propose and discuss new vision of geomarketing as a tool for promotion of regional sustainable development. Integrated object-oriented conception of geomarketing was designed by adoption and elaboration of some new ideas and approaches, such as “place marketing”, “non-profit marketing”, “counter-marketing”, “collaborative spatial decision-making”, “endogenous regional development”, “regional sustainable development”, “public-private partnership”. We explore how geomarketing in such a comprehension may be implemented in business and public administration, regional development policy making on example of some Ukrainian firms, regional governments, and communities. The proposed geomarketing conception is based on integration of three different interpretations of geomarketing: 1) …

Mediation Of Host Selection And Oviposition Behavior In The Diamondback Moth Plutella Xylostella And Its Predator Chrysoperla Carnea By Chemical Cues From Cole Crops, G. V.P. Reddy, E. Tabone, M. T. Smith

Faculty Publications

Host plant-mediated orientation and oviposition by diamondback moth (DBM) Plutella xylostella (L.) (Lepidoptera: Yponomeutidae) and its predator Chrysoperla carnea Stephens (Neuroptera: Chrysopidae) were studied in response to four different brassica host plants: cabbage, (Brassica oleracea L. subsp. capitata), cauliflower (B. oleracea L. subsp. botrytis), kohlrabi (B. oleracea L. subsp. gongylodes), and broccoli (B. oleracea L. subsp. italica). Results from laboratory wind tunnel studies indicated that orientation of female DBM and C. carnea females towards cabbage and cauliflower was significantly greater than towards either broccoli or kohlrabi plants. However, DBM and C. carnea males did not orient towards any of the …

Response Of Grassland Birds To Fire On A Wisconsin Sand Prairie Over An 18-Year Period, Greg Geller, David Sample, Rich Henderson

Proceedings of the North American Prairie Conferences

The relative abundance of grassland birds was estimated on an 81-ha (200-acre) dry to dry-mesic sand prairie in south, west Wisconsin over an 18-year period (1987-2004). Birds were surveyed three times during the breeding season on seven, 2-ha (5-acre) strip transects in six different burn units. We compared results to time since fire and other habitat features. The average rotation of prescribed fires in the burn units ranged from three to six years. Seven species were selected for detailed analysis. These were grasshopper sparrows (Ammodramus savannarum),-18-year average of 1.33 birds per ha, field sparrows (Spizella pusilla) …

The Effects Of Habitat Resolution On Models Of Avian Diversity And Distributions: A Comparison Of Two Land-Cover Classifications, Joshua Lawler, Raymond O'Connor, Carolyn Hunsaker, K. Bruce Jones, Thomas Loveland, Denis White

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Quantifying patterns is a key element of landscape analysis. One aspect of this quantification of particular importance to landscape ecologists is the classification of continuous variables to produce categorical variables such as land-cover type or elevation stratum. Although landscape ecologists are fully aware of the importance of spatial resolution in ecological investigations, the potential importance of the resolution of classifications has received little attention. Here we demonstrate the effects of using two different land-cover classifications to predict avian species richness and the occurrences of six individual species across the conterminous United States. We compared models built with a data set …

Predicting Condition Of Small Estuarine Systems Along The United States' Atlantic Coast, Jeffrey W. Hollister

Open Access Dissertations

Anthropogenic activities are known to degrade the ecological condition of estuaries. Also, numerous studies find links between landscape structure and estuarine condition. From these relationships, it is possible to build predictive models of estuarine condition. In this study, I examined issues of data quality, scale, and statistical approach to developing predictive models of estuarine sediment metal concentrations in the Mid-Atlantic region of the United States. I assessed the accuracy of the National Land Cover Dataset (NLCD) at multiple scales by comparing it with reference data from Rhode Island and Massachusetts. Area of developed lands, agriculture, forest and water had acceptable …

Comparison Of Harvested And Nonharvested Painted Turtle Populations, Tony Gamble, Andrew M. Simons

Biological Sciences Faculty Research and Publications

Painted turtles (Chrysemys picta) are commercially harvested in large numbers in Minnesota for sale to biological supply companies and the pet trade. We investigated the possible effects of this harvest by comparing size, demography, and catch rates of painted turtles in 12 harvested and 10 nonharvested painted turtle populations in 2001 and 2002. We correlated turtle catch rates to harvest status, and harvested lakes had a lower catch-per-unit-effort than nonharvested lakes. Harvest had minimal effect on the size of turtles captured, and we found no significant differences in the count of male:female:juvenile turtles among lakes of different harvest …

Consequences Of Reservoir Drainage On Downstream Water Chemistry, Suspended Sediment, And Nutrients, Southwest Missouri, Mark W. Bowen

Graduate Theses/Dissertations

Construction and subsequent draining of reservoirs can have dramatic affects on the release of nutrients and sediments to waterways. This study describes how the temporary draining of a small reservoir for dam repair influences downstream water quality. The Valley Mill Reservoir has a surface area of 6.1 hectares and volume of 150,000 m3 when filled. Water chemistry monitoring and water sampling were performed at six sites during baseflow and ten sites during runoff events for one year. Water samples were analyzed for total nitrogen (TN), total phosphorous (TP), and total suspended sediment (TSS) concentrations. Results indicate that draining of Valley …

The Ecological Causes And Consequences Of Prey Choice And Ontogenetic Niche Shifts In The Common Goby, Angus Charles Jackson

School of Biological and Marine Sciences Theses

Foraging behaviour of the common goby, Pomatoschistus microps was investigated in both the United Kingdom and Sweden, with the aim of establishing causes and consequences of prey choice and ontogenetic shifts in diet. Goby life-cycle could be clearly divided into two stages, where prey choice changed abruptly from meio- to macrofauna at a standard length of 30 mm. This diet-shift maximised net energy intake rates, as illustrated by a quantitatively validated optimal foraging model. Intrinsic mechanisms were of greater importance than extrinsic factors in driving this shift. Metabolism, the primary prey choice determinant, revealed canalised and predictable diet shifts in …

Ecology And Behaviour Of Postlarvae And Juveniles Of The Velvet Swimming Crab Necora Puber (L.), James Tony Lee

School of Biological and Marine Sciences Theses

Ecological studies of early benthic stages of brachyurans are rare for most of the species, leaving a gap in the understanding of processes regulating the recruitment to adult populations. The velvet swimming crab Necora puber (L. ) is a valuable commercial species where most of studies have been focused on the adult population. Little is known about the supply-side ecology and the post-settlement processes that affect the dynamics of the adult populations. The aims of the present study were to investigate the physical processes affecting the supply of recruits to the nearshore, to examine the processes associated with habitat selection …

Analysis Of Bacterial Diversity And Biogeography At The Central Arizona-Phoenix Long Term Ecological Research (Cap Lter) Site, Brian Anthony Rash

LSU Doctoral Dissertations

The limiting factor involved in past assessments of soil bacterial diversity when using culture-independent techniques has often been the lack of sampling and replication. As a result, analyses of community structural shifts across soil environments have lacked statistical power. In this study, 23 16S rRNA gene clone libraries consisting of over 11,000 clones were constructed from soils at the Central Arizona Phoenix Long Term Ecological Research (CAP LTER) site. Subsequent ARDRA fingerprinting and partial 16S rRNA gene sequencing allowed for a more robust investigation of various components that may explain any observed variations in bacterial species composition. The designated land …
