Explanations For The Infrequent Cowbird Parasitism On Common Grackles, Brian D. Peer, Eric K. Bollinger

Faculty Research & Creative Activity

We determined the factors responsible for the lack of parasitism on Common Grackles (Quiscalus quiscula) by Brown-headed Cowbirds (Molothrus ater). We found no evidence of parasitism on the 401 grackle nests we monitored in east-central Illinois. By the time cowbirds began laying eggs, 88.5% of all grackle nests were beyond the point of successful parasitism. Grackles rejected cowbird eggs more frequently during the prelaying stage of the nesting cycle (38.2%) compared to later stages (12.3%). Thirty-three cowbird eggs and nestlings were cross-fostered into grackle nests. Data were collected on 15 cowbird nestlings, of which three fledged. The cross-fostered cowbird eggs …

Observations On Reproduction, Isozyme Patterns, And Meristics In Mosquitofish (Pisces: Poeciliidae) From West Virginia, Matt Mcreynolds

Theses, Dissertations and Capstones

Prior to 1988, two subspecies of the mosquitofish Gambusia affinis (G. a. affinis and G. a. holbrooki) were recognized along the Gulf and Atlantic Coasts of the United States. Based on electrophoretic analysis, subsequent investigators recognized G. holbrooki and G. affinis as separate species. Populations in drainages west of Mobile Bay were considered G. affinis, and those east of this divide being G. holbrooki. The only mosquitofish population in West Virginia is found in the Meadow River wetlands (1392 ha). This wetland complex is located at the western end of Greenbrier County in the Allegheny Mountain Province. …

In Vivo Incorporation Of Tritium To Measure Lipogenesis In Red Skeletal Muscle: Significance Of A Nonlipogenic Diet In La/N-Fa(K)("Corpulent") And Zucker Fa Rat Strains, Karin Traci Mann

Theses, Dissertations and Capstones

Skeletal muscle lipogenesis in rodents may equal that of liver but its importance in the obese animals is not known. We evaluated the rate of fatty acid and triglyceride synthesis and storage content in red skeletal muscles, liver, inguinal fat, and retroperitoneal fat of the LA/N-fa^k (“corpulent”) and Zucker fa obese rat strains. Obese-lean pairs of both rat strains, weaned at 32 days, fed a nonlipogenic diet (54% starch for 21 days) were either dosed with 2 µCi 3H-H² O per gram of body weight and tested after 60 minutes for whole body 3H-incorporation into fatty acids and …

An Analysis Of The Variation Within Cratoxylum Arborescens (Clusiaceae) In Malesia, A.C. Church, P.F. Stevens

Biology Department Faculty Works

The variation within the widespread West Malesian species Cratoxylum arborescens (Vahl) Blume was analyzed and three distinctive variants were found. These are recognized formally as varieties, var. arborescens, var. miquelii King, and var. borneense A.C. Church & P.F. Stevens. A key and full descriptions are given. The characters employed to delimit the three taxa are discussed and the selection of varietal rank is justified.

Xantusia Vigilis (Desert Night Lizard) And Sceloporus Magister (Desert Spiny Lizard). Predation And Diet., Stephen C. Adolph, Marc Perkins '98, Stephen Granite '97, Wendy Hein '97

All HMC Faculty Publications and Research

Here, we report evidence of predation on Xantusia vigilis by Sceloporus magister. We collected a yearling female S. magister (71 mm SVL, mass = 13.6 g) on 24 July 1996, 5 km SE of Llano, Los Angeles County, California, USA (34°29'N, 117°46'W, elevation 1120 m). In the laboratory, on 29 July, the S. magister deposited a fecal pellet that contained part of a Xantusia vigilis body, including sections of dorsal and ventral integument and both hind limbs.

Description Of Tadpoles Of Three Species Of Scinax (Anura: Hylidae), Rafael O. De Sá, Rocjard Wassersig, Arturo I. Kehr

Biology Faculty Publications

Larval morphological characteristics have been used to cluster species of Scinax in seven species groups and to support the monophyly of some of these groups. However, our present knowledge of Scinax tadpoles is incomplete; currently, tadpoles of only 21 of the approximately 80 recognized species have been described. Herein, we describe and illustrate the external morphology and oral disc characteristics of larval Scinax berthae, S. nebulosa, and S. boesemani. The presence of a "labial arm" supporting the P3 tooth row in S. boesemani, and its absence from S. nebulosa, is discussed in the light of our limited knowledge of tadpoles …

Bat House Use In Central Florida, With Emphasis On Nycticeius Humeralis And Tadarida Brasiliensis Cynocephala, Laura Seckbach Finn

Retrospective Theses and Dissertations

Bat houses and roost sites utilized by Tadarida brasiliensis and Nycticeius humeralis were studied in four central Florida counties. Temperatures were monitored in occupied roosts and in bat houses. It was determined that the presence of bats affects roost temperature. The mean temperature in the bat house that was preferred at the Seminole Community College (SCC) site was above ambient temperature a significantly greater amount of time than mean temperature in the other style houses located at that site. A colony of bats roosting in buildings on the property of SCC was successfully relocated into bat houses located .4 kilometers …

Description Of The Tadpole Of Atelopus Tricolor, E. O. Lavilla, Rafael O. De Sá, Ignacio De La Riva

Biology Faculty Publications

Tadpoles of Atelopus belong to the gastromyzophorous guild of exotrophic larvae (Altig and Johnston, 1989), and are characterized by the presence of a conspicuous abdominal sucker and an expanded oral disc. The larvae of several Atelopus species have been described previously: A. varius (Starrett, 1967); A. certus, A. ignescens, and A. spumarius (Duellman and Lynch, 1969); A. cruciger (Mebs, 1980); A. flavescens (Lescure, 1981); A. peruensis (Gray and Cannatella, 1985); and A. subornatus (Lynch, 1986). These represent about 15% of the known species in the genus (Frost, 1985; Duellman, 1993). Although Atelopus tricolor was originally described at the beginning of …

Chemical Communication In House Mice (Mus Musculus): Can They Recognize Gender From The Anogenital, Harderian Gland Or Mouth/Nose Odor?, Dawn Michele Andrews

Dissertations and Theses

Identifying the sensory systems animals employ to communicate chemically and the function of the chemical signals facilitates further understanding of chemical communication. Increased knowledge of how animals use the olfactory and vomeronasal systems in order to interpret the meaning of body odors will aid in developing a more detailed organization of chemosensory pathways. The message that each body odor contains can change from species to species.

The purpose of this thesis was to study three previously untested body odors in house mice (M. musculus) for their role in gender recognition of conspecifics. These odors are the anogenital (feces, …

A Re-Evaluation Of Hotspot Settlement In Lekking Sage Grouse, Robert M. Gibson

School of Biological Sciences: Faculty Publications

Recent analyses of avian leks have come to conflicting conclusions concerning the role of male settlement on female traffic hotspots. This issue was re-examined in the sage grouse, Centrocercus urophasianus, using data on prenesting movements of radio-tagged females and the dispersion of lekking males collected during a 10-year field study. As expected with hotspot settlement, leks were preferentially located in areas through which females traveled between wintering and nesting ranges before mating. In addition, the distribution of males among leks was related proximately to variation in numbers of females visiting each lek during the mating period and ultimately to …

Female Choice In Sage Grouse: The Roles Of Attraction And Active Comparison, Robert M. Gibson

School of Biological Sciences: Faculty Publications

Previous studies of female choice in sage grouse Centrocercus urophasianus have implicated both the acoustic quality and repetition rate of the stereotyped strut display as putative cues for female choice. Stages in the choice process at which specific components of male courtship display influence female decisions were investigated using field observations of female premating behavior. Females visited a subset of territorial males and then actively chose one of these as a mate. The order in which males were visited suggested that females searched until an acceptable mate was found, rather than employing a “best-of-n” tactic. Numbers of females visiting a …

Offshore Constitutional Settlement 1995, H. G. Brayford, G. E. Lyon

Fisheries Management Papers

The Offshore Constitutional Settlement OCS is a legal arrangement between the Commonwealth and State Governments, and defines control over the fisheries which operate off each State of Australia. For the Western Australian coast, the first set of arrangements took effect in 1987. The OCS of 1995 specifies five arrangements, under which the fisheries inside the 200 nautical mile approximately 370 km limit of the Australian Fishing Zone AFZ come under either State, Commonwealth, or joint control.

Use Of The (3)H-Tetracycline Rat Model In The Study Of Skeletal Compartmentalization And Metabolism Of Calcium In The Maturing Male And Female Rat And The Role Of The Skeleton In Calcium Homeostasis In The Adolescent Male Rat, Darrin Lee Demoss

Theses, Dissertations and Capstones

The (3)H-tetracycline bone labeling procedure was employed to monitor bone resorption from urinary loss curves in male and female rats of various ages. In addition, whole body dry skeletal mass and the loss of (3)H-tetracycline from individual bones was determined. It was found that the dry skeletal mass/body mass ratio of 24-week-old females was 30-40% greater than that for males. The urinary loss of (3)H-tetracycline was described by a double exponential equation indicating the presence of two distinct and independent exchangeable bone compartments. Both compartments decrease in size with age, but their label loss activities were different. The label loss …

Dietary Overview Of Hemidactylus Turcicus With Possible Implications Of Food Partitioning, Daniel Saenz

Faculty Publications

A stomach content analysis was conducted on Hemidactylus turcicus, the Mediterranean gecko, from 19 April 1990 to 15 October 1990, on the campus of Stephen F. Austin State University, Nacogdoches, Texas. Geckos (N = 167) were placed into four size groups based on snout-vent-length (5 29 mm, 30-39 mm, 40-49 mm, and z 50 mm) and three microhabitat groups based on perch height (those occupying perch sites < 1.52 m, 2 1.52 m to 5 3.05 m, and > 3.05 m). Stomach contents were analyzed and sex, size, and microhabitat groups were compared using Schoener's percent overlap index. Volumetrically, the most important prey items taken were Orthoptera, Lepidoptera, and Isopoda. Geckos of …

Captive Environmental Influences On Behavior In Zoo Drills And Mandrills (Mandrillus), A Threatened Genus Of Primate, Erik Terdal

Dissertations and Theses

Drills (Mandrillus leucophaeus) are an endangered species of African monkey (Cercopithecidae), and their sole congener the mandrill (Mandrillus sphinx) is vulnerable to extinction. Both species are threatened in the wild by deforestation and hunting.

Drills have a poor record of captive reproduction. Many individuals appear to have behavioral deficiencies which interfere with reproduction. Thus, the zoo population of drills does not serve as a “hedge” against the species’ total extinction: drills are endangered in captivity as well as in the wild. Mandrills, by contrast, reproduce well in captivity. Information on the behavior of mandrills in captivity may help zoo managers …
