Breeding Season Distribution Of Cerulean Warblers In Arkansas In The 1990s, Douglas A. James, Christopher J. Kellner, Jan Self, Jerry Davis

Journal of the Arkansas Academy of Science

The Cerulean Warbler (Dendroica cerulea) has been declining in numbers in its North American nesting range, and the same is true in Arkansas. To provide specific sites that can be monitored in the future, this study describes places where the bird was documented in the state in the 1990s. The warbler was found in mature deciduous forest in both upland and bottomland situations but was most abundant in the upland Ozark forests and uncommon in other regions of the state. Most (70%) of the occupied sites were on federal and state lands. Pattern of overall distribution was essentially the same …

Aspects Of The Taxonomy And Ecology Of The Ground Beetle (Coleoptera: Carabidae) Assemblage Of The Swan Coastal Plain : (With Particular Reference To Habitat Fragmentation And The Quindalup Dune System), Nadine A. Guthrie

Theses: Doctorates and Masters

Long term studies encompassing seasonal variation in abundance and species present, forming base-line phenological data, arc required to understand the responses of the carabid (Ground Beetle) fauna to major habitat changes. In addition, few habitats unaffected by human disturbance remain in Australia, and evaluation of these fauna in these areas is required before further habitat loss occurs. Generally an unknown group of terrestrial predatory invertebrates in Australia, carabids have been the subjects of few ecological studies in this country. This restricts the utility of the Carabidae in environmental or conservation assessment programs in Australia. A study was initiated to assess …

Way-Finding And Landmarks: The Multiple Bearings Hypothesis, Alan C. Kamil, Ken Cheng

Papers in Behavior in Biological Sciences

Clark’s nutcrackers (Nucifraga columbiana) are capable of very precise searching using the metric relationships between a goal and multiple landmarks to relocate the goal location. They can judge the direction more accurately than the distance to a landmark when the landmark is distant from the goal. On the basis of these findings, we propose that nutcrackers use a set of bearings, each a measure of the direction from the goal to a different landmark, when searching for that goal. The results of a simulation demonstrate that increasing the number of landmarks used results in increasingly precise searching. This …

Search For A Hidden Goal By Clark's Nutcrackers (Nucifraga Columbiana) Is More Accurate Inside Than Outside A Landmark Array, Brett M. Gibson, Alan C. Kamil

Papers in Behavior in Biological Sciences

In three experiments in which an open-room delayed response task was used, we explored how Clark's nutcrackers use landmarks to search for a hidden goal when multiple potential goal locations were present. In Experiment 1, nutcrackers presented with three spatial samples were able to use relative local cues from an array that changed positions throughout a session to return to a hidden goal during a test. In Experiment 2, the number of samples varied from one to three prior to the test. The nutcrackers performed as well with one sample as with two or three samples. In Experiment 3, we …

The Use Of Relative And Absolute Bearings By Clark's Nutcrackers, Nucifraga Columbiana, Juli E. Jones, Alan C. Kamil

Papers in Behavior in Biological Sciences

Two groups of Clark's nutcrackers were trained to find buried seeds whose location was defined by a constant angle from two landmarks whose interlandmark distance and position in the room varied across trials. The first group had a landmark array that was always placed in the same orientation with respect to the walls, allowing the animals to use both relative and absolute bearings. The second group had a landmark array that rotated across trials so that only relative bearings could be used to locate the seeds. The birds in each group learned the task and transferred to new interlandmark distances …

Review Of Evolution And Cognition, Edited By Cecilia Heyes And Ludwig Huber., Alan Kamil

Papers in Behavior in Biological Sciences

Heyes and Huber have edited a volume that surveys much of the current research into cognition in animals, reflecting the strengths and weaknesses of this field. The book is divided into five sections. In the first part, titled “Orientations,” four authors lay out their basic general views of the field. The first two chapters in this section are by the editors. First, Heyes makes the case for an approach to evolutionary psychology that she labels “in the round,” an approach that would encompass studies of human and nonhuman animals alike and include a broad range of contemporary evolutionary approaches. This …

New Host And Geographic Records For Two Protostrongylids In Dall's Sheep, Susan J. Kutz, A. M. Veitch, Eric P. Hoberg, B. T. Elkin, Emily J. Jenkins, L. Polley

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Biodiversity survey and inventory have resulted in new information on the distribution of Protostrongylidae in Dall’s sheep (Ovis dalli dalli) from the Northwest Territories (Northwest Territories, Canada) and from Alaska (Alaska, USA). In 1998, Parelaphostrongylus odocoilei adults were found for the first time in the skeletal muscles of Dall’s sheep in the Mackenzie Mountains (Northwest Territories). Adult P. odocoilei were associated with petechial and ecchymotic hemorrhages and localized myositis; eggs and larvae in the lungs were associated with diffuse granulomatous pneumonia. Experimental infections of the slugs Deroceras laeve and Deroceras reticulatum with dorsal-spined first-stage larvae assumed to be …

Recolonization Of The Flicker And Other Notes From Isla Guadalupe, Mexico, Paul R. Sweet, George F. Barrrowclough, John Klicka, Liliana Montanez-Godoy, Patricia Escalante

Ornithology Program (HRC)

During a visit to Isla Guadalupe from 31 May to 3 June 1996, we documented three species new to the island, the Barn Owl, Swainson's Thrush, and Hooded Oriole, and established first breeding records for the European Starling and Western Meadowlark. Red-shafted Flickers are now breeding on the island, representing a recent recolonization from the mainland following the extinction of the endemic population. We investigated the validity of Colaptes auratus rufipileus and concluded that it doesn’t meet the standard for phylogenetic species but differs from C. a. collaris at the 75% level usually associated with subspecific rank. Damage to the …

Chondrocranium And Visceral Skeleton Of Atelopus Tricolor And Atelophryniscus Chrysophorus, E O. Lavilla, Rafael O. De Sá

Biology Faculty Publications

Atelopus tricolor and Atelophryniscus chrysophorus have gastromyzophorous tadpoles. Aside from specific differences, the larval chondrocrania and visceral skeletons show several shared character states, including an almost quadrangular, open chondrocranium , cornua trabeculae with expanded tips, cartilago suprarostralis as a single element, a posteriorly projected arcus subocularis quadrati, a closed muscular tunnel, and a simplified branchial basket, with only three pairs of ceratobranchiales. They are compared with diverse character states of suctorial larvae considering them as causally related to the stream life adaptations.

Managing Wetland Vegetation For Marsh Birds And Waterfowl At Carlyle Lake Wildlife Management Area, Il, Matthew W. Bowyer

Masters Theses

The high cost of restoring and managing wetlands warrants careful assessment of their management potential. We designed this study to provide basic information on how seed banks and hydroperiod influence the development of habitat for migratory birds in restored wetlands at Carlyle Lake Wildlife Management Area (CLWMA). The objectives were to: (1) survey the composition of the seed banks; (2) investigate the effects of early- vs. late-drawdowns on the germination and growth of these plants; and (3) monitor the use of these communities by wetland birds during migration and the breeding season. The study was conducted on a marsh complex …

Isolation Effects Of Aquatic Habitat Fragmentation On Greenside (Etheostoma Blennioides) And Fantail (Etheostoma Flabellare) Darters, Rita M. Klein

Masters Theses

Aquatic habitat fragmentation is defined as the lack of connectivity between upstream and downstream populations and can occur along two gradients, the longitudinal gradient and the lateral gradient. The longitudinal gradient focuses on objects within the stream and is concerned with the disruption of stream flow, which is normally brought about by the presence of dams and bridges. Fragmentation along the lateral gradient, on the other hand, examines factors outside of the stream and is related to any loss or modification of the surrounding riparian zone.

In Illinois within the last 100 years, stream habitats have become increasingly fragmented by …

Diversity And Abundance Of Seaweeds On The Coral Reef Flats At Cape Rachado, West Coast Peninsular Malaysia, Jillian Lean Sim Ooi

Student Works (2000-2009)

Three sites on the fringing coral reef flats at Cape Rachado, West Coast Peninsular Malaysia, were selected for the study of seaweed diversity and abundance. Each of these sites was identifiable with exposure to a particular environmental stress. Site A suffered from heavy loads of total suspended solids (TSS) caused by the removal of its adjoining coastal mangrove stand. Site B, by virtue of its accessibility and location on a popular stretch of beach, received a greater number of swimmers and beachwalkers. Water effluent (sewage) outlets from the various resorts lining the coast were observed at sites A and B. …

Diversity And Abundance Of Phytoplankton In Tasek Bera, Pahang, Soo Hui Tang

Student Works (2000-2009)

Tasek Bera, located in southwest of Pahang state, is Malaysia's largest freshwater swamp and lake system. It is one of the remaining examples of a lowland alluvial riparian swamp system. Tasek Bera was designated as Malaysia's first "Wetlands of International Importance" under the Ramsar Convention in November 1994. The water quality of Tasek Bera was monitored from April to October 1998 to assess environmental conditions affecting phytoplankton assemblages. Measurement of physical and chemical parameters at selected sites ranged as follows : pH (4.45 to 6.73), temperature (25.3 to 33.3 °C), dissolved oxygen (0.40 to 5.80 mgL⁻¹), water depth (0.15 to …

The Biology, Life History, And Taxonomy Of Celastrina Neglectamajor (Lycaenidae: Polyommatinae)., Harry Pavulaan, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

The biology and life history of Celastrina neglectamajor is described. This lycaenid butterfly was first described from West Virginia, United States by 19th century lepidopterist, William H. Edwards, as a redescription of Lycaena pseudargiolus (Boisduval & Le Conte). Edwards provided evidence of its unique late spring flight, Appalachian affinity, and larval host Cimicifuga racemosa (Ranunculaceae). Edwards and subsequent authors, most notably Samuel Scudder of New England, treated it as an infrasubspecific form of the common eastern Celastrina ladon. In 1908 Tutt applied the form name neglectamajor, describing it from one of Edwards’ 1884 figures. For nearly a century, …

Hydrologic Analysis Of The Major Tributaries Within The Lower Dan River Watershed Between Milton, Nc And Paces, Va, Juliet Jefferson Brown

Theses & Honors Papers

According to the Clean Water Act of 1972, Virginia is required to develop Total Maximum Daily Loads (TMDLs) for its impaired waters. A TMDL is the maximum amount of particular contaminants that a body of water can accept, without violating federal and state water quality standards. Approximately 130 waters have been targeted for TMDL development, with fecal coliform contamination cited as one of the top five violations.

The purpose of this study was to examine a ten-mile segment of the Dan River that has been designated as impaired, along with seven tributaries that contribute to that segment. The segment is …

Do Timing And Pattern Of Myogenesis Correlate With Life History Mode In Anurans?, Matthew T. Smetanick, Rafael O. De Sá, Gary P. Radice

Biology Faculty Publications

The timing and pattern of myogensis varies among anurans that have been studied and the different patterns may provide useful phylogenetic information. Specific myogenic markers have been described (Muntz, 1975; Kielbowna, 1981; Boudjelida & Muntz, 1987; Radice et al., l989) and they can provide information on evolutionary changes for closely related lineages within a clade. For example, we previously compared first appearance of a muscle-specific protein, first twitch of axial muscle, onset of multinucleation within axial myotome, and first heartbeat in two pipid genera (Smetanick, et al., 1999). We found that although the timing of myogensis differed, the sequence of …

Comparison Of Coastal Fringe And Interior Forests As Reserves For Marbled Murrelets On Vancouver Island, Alan E. Burger, Volker Bahn, Angeline R.M. Tillmanns

Biological Sciences Faculty Publications

Much of the protected habitat available to the threatened Marbled Murrelet Brachyramphus marmoratus and other old-growth associated species in the Pacific Northwest is in narrow strips along the coast (e.g., parks and scenic fringes). Using data over two years from three watersheds on southwest Vancouver Island, we show that such shoreline strip forests represent suboptimal habitat for murrelets. Murrelet detections, including circling and subcanopy behaviors, were significantly lower at 30 coastal stations (20–250 m from the shoreline edge) than at 30 interior stations (1.5–21.0 km inland). Densities of predators were significantly higher at the coastal stations. The coastal trees were …

Electrophysiological Studies Of Olfaction In The Whip Spider Phrynus Parvulus (Arachnida, Amblypygi), Eileen Hebets, Reginald F. Chapman

Eileen Hebets Publications

The olfactory response of the whip spider Phrynus parvulus from Costa Rica was examined using a technique analogous to that used for insect electroantennograms on the tarsi of the antenniform legs which bear multiporous sensilla. Responses to 42 chemicals representing different chain lengths of alkanes, carboxylic acids, alcohols, aldehydes, and ketones, as well as some esters, monoterpenes, and phenolics were examined. Fifty-four percent of the chemicals tested elicited responses. Concentration–response curves were generated for guaiacol, hexanal, methyl salicylate, benzaldehyde, octanoic acid, and linalool. Guaiacol, benzaldehyde, and hexanol elicited the greatest responses and no differences were detected between the sexes. Compounds …

Comparison Between Two Analytical Methods For Fecal Coliform Analysis In Natural Water: Membrane Filtration And Multiple Tube Fermentation, Mona M. Hafez

Theses & Honors Papers

This study compares two different analytical methods for the determination of coliform bacteria within natural waters. The two methods are: 1) membrane Filtration, and 2) multiple tube fermentation. Water samples from ten different locations within the Appomattox River watershed were collected by technicians from the Piedmont Soil and Water Conservation District and the Piedmont Region TMDL Initiative in Farmville, Virginia.

The Membrane filtration (MF) method utilizes m-FC broth to isolate and differentiate total fecal coliform bacteria (E.coli, Klebsiella, Pseudomonas) in natural water samples. A 1% dilution of each water sample is filtered through a 0.45 micron (um) Millipore filter …

Small Mammal Communities In Riparian And Upland Habitats On The Upper Coastal Plain Of Virginia, A. Scott Bellows, Joseph C. Mitchell

Virginia Journal of Science

We compared small mammal communities between riparian (stream corridor) and nearby upland habitats in a hardwood forest ecosystem on Fort A.P. Hill, Caroline County, Virginia. We used a combination of small-scale drift fence/pitfall trap arrays and snap traps to capture small mammals during April – October 1998, with an additional winter sample in January 1999. We captured seven small mammal species at 14 sites (7 pairs). Numbers of species were not significantly different between habitat types. Bray-Curtis polar ordinations showed that plant and small mammal community compositions were similar in upland sites and that these communities were most varied in …

Observations On Amphibians And Reptiles In Burned And Unburned Forests On The Upper Coastal Plain Of Virginia, Joseph C. Mitchell

Virginia Journal of Science

I evaluate the results of a short-term study on the effects of prescribed burning on terrestrial amphibians and reptiles on Fort A.P. Hill, Caroline County, Virginia. Six species of amphibians and reptiles were observed in unburned sites and eight species were observed in burned sites. More individual amphibians (46) were observed in unburned stands than in burned stands (15). Adults of two species (Bufo americanus, Plethodon cinereus) were found dead under logs in the still smoldering prescribed burn. The results of this study suggest that prescribed burning may have some negative effects on amphibians and reptiles. Because …
