Current Status Of Northern Beardless-Tyrannulet And Tropical Parula In Bentsen-Rio Grande Valley State Park And Santa Ana National Wildlife Refuge, Southern Texas, Timothy Brush

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

There are no published records of Northern Beardless-Tyrannulet (Camptostoma imberbe) and Tropical Parula (Parilla pitiayumi) nesting in the Lower Rio Grande Valley of Texas since the late 1940s. In this 1996- 1998 study, both species were confirmed nesting at Santa Ana National Wildlife Refuge, and Northern Beardless-Tyrannulet was also confirmed at Bentsen Rio Grande Valley State Park. Most Northern Beardless-Tyrannulet nests were between clumps of ball-moss (Tillandsia recurvata) in cedar elm (Ulmus crassifolia) trees, and nests were active from 21 March-23 September. Only fe. males build nests or incubate. Two-three young fledged per successful nest, but three nests were abandoned …

Recent Northern Records Of The Nine-Banded Armadillo (Dasypodidae) In Nebraska, Patricia W. Freeman, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Examination of the distribution of nine-banded armadillo in Nebraska reveals that these animals may be entering the state from two directions. The animals in Chase, Dundy, and Furnas counties appear to be closely associated with the Republican River and its tributaries and probably reached the state along these riparian habitats from northwestern Kansas and northeastern Colorado. Records in the central and eastern part of Nebraska are not closely tied to one river system. For the specimen from Ord to have followed watercourses, it would have needed to follow the Big or Little Blue rivers, crossed to the Platte River, and …

Management Of The Houtman Abrolhos System., Kim Nardi, Abrolhos Islands Management Advisory Committee

Fisheries Management Papers

The Abrolhos System is the Houtman Abrolhos Islands and adjoing State Territorial Waters. It is an important part of the Western Australian environment. Has major significance in conservation of flora and fauna and also in geological terms. The waters adjoining State Territorial Waters contain some of the most highly valued marine systems in the State. These include sites of historical shipwrecks in Australia. The are of great interest to visitors and support a relatively small but growing recreation and tourism industy.

The area is integral to the Western rock lobster fishery, which is that State's premier primary industries. The Abrolhos …

Endemicity And Regiona[L] Biodiversity In Nebraska's Breedin[G] Avifauna, Paul A. Johnsgard

Nebraska Bird Review

I estimate that 215 bird species currently breed or have previously bred in Nebraska. This number compares with a total of 330 species that breed or have bred in the Great Plains region south of Canada, as I defined that region in my book on the breeding birds of the Great Plains (Johnsgard, 1979).

Grasslands or potential grasslands make up about 81 percent of the Great Plains' vegetation, and probably represented about 96 percent of Nebraska's original vegetation. Only in the Sandhills region is that vegetation type still essentially intact; the tall-grass prairie of eastern Nebraska is Virtually gone. In …

Potential Of The Entomopathogenic Fungus, Metarhizium Anisopliae (Metsch.) Sorokin For Control Of The Legume Flower Thrips, Megalurothrips Sjostedti (Trybom) On Cowpea In Kenya, S. Ekesi, N. K. Maniania, K. Ampong-Nyarko, I. Onu

All Peer-Reviewed Publications

Field experiments were conducted at Mbita, western Kenya for two seasons to evaluate the potential of the entomopathogenic fungus, Metarhizium anisopliae (Metsh.) Sorokin, for biological control of the legume flower thrips, Megalurothrips sjostedti (Trybom), on cowpea. An ultra-low-volume (ULV) oil/aqueous formulation and a high-volume (HV) aqueous formulation of conidia were applied three times each at two concentrations of 1 x 1011 and 1 x 1013 conidia ha-1. Compared with the untreated controls, both formulations significantly reduced thrips populations and plant damage in both seasons. Adult insects collected from fungal-treated plots and reared in the laboratory showed a high mortality due …

Bird Use Of Riparian Vegetation Along The Truckee River, Califonia And Nevada, Suellen Lynn, Michael L. Morrison, Amy J. Kuenzi, Jennifer C. C. Neale, Benjamin N. Sacks, Robin Hamlin, Linnea S. Hall

Great Basin Naturalist

The Truckee River in California and Nevada is subject to diverse water regimes and a corresponding variety of flow rates. Original riparian vegetation has been altered by these variable flow rates and by a variety of human uses resulting in loss of native riparian vegetation from its historic extent. We conducted bird surveys along the Truckee River during spring 1993 to (1) determine relationships between birds and the present vegetation; (2) determine the importance of different vegetation types to sensitive bird species that have declined recently in the western United States due to competition from exotic plant species, cowbird ( …

Genetics Of The Interval From Weaning To Estrus In First-Litter Sows: Correlated Responses, J. Ten Napel, T. H. E. Meuwissen, R. K. Johnson, E. W. Brascamp

Department of Animal Science: Faculty Publications

The objective of this study was to evaluate relationships between rebreeding performance and growth performance (n = 3,777 gilts) and rebreeding performance and reproductive performance (n = 2,242 sows). Our data were from a selection experiment for shorter intervals from weaning to estrus after the first parity (IWE), involving Dutch Landrace pigs, in which a selection line and a control line without selection were maintained for eight generations. Relationships were evaluated before and after transforming IWE to normal interval (NI; IWE &#; 7 d), prolonged interval (PI; IWE > 7 d), and incidence of a prolonged interval (INC). Heritabilities of NI, …

Fisheries Research Report No. 112 - Final Report, Frdc Project 94/075: Enhancement Of Yabby Production From Western Australian Farm Dams, Fisheries Western Australia, Fisheries Research And Development Corporation

Fisheries Research Reports

Farmers receive higher prices per kilo for large yabbies. Yabby farmers have reported that the majority of yabbies trapped from farm dams are below market size (< 30 g) and therefore of no economic value. In addition, farmers also report that while dams produce large yabbies when first harvested, after a number of years the proportion of large animals gradually decreases.

To identify why yabbies in farm dams stunted and how farmers could increase the size of small yabbies the project had three main experimental areas.

Research station experiments: A field research station consisting of 25 ponds was constructed for running replicated, randomised and reproducible experiments, with controls, in an environment that simulated farm dams. In addition, these ponds were large enough to provide an adequate sample number of yabbies at realistic industry stocking …

Grassland Birds And Habitat Structure In Sandhills Prairie Managed Using Cattle Or Bison Plus Fire, Randall Griebel, Stephen L. Winter, Allen Steuter

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Grassland birds are known to respond to specific changes in habitat structure, such as plant height and density. However, the response of grassland bird communities to management induced changes in the regional habitat mosaic are less well understood. Grazing by ungulates and fire regimes play an important role in defining the habitat mosaic in the Great Plains. We provide information on bird abundance, distribution, and habitat structure from similar sandhill prairie landscapes managed traditionally with grazing by cattle (Bos taurus) and by a dynamic bison (Bos bison)-plus-fire regime. Although the two management regimes are dissimilar, only …

Changes In Small Mammal Community Attributes Associated With Increasing Pine Stand Age In Managed Pine Plantations In Southeastern Virginia, James Douglas Dolan

Biological Sciences Theses & Dissertations

Loblolly pine plantations were examined at different ages to identify small mammal community attributes in relation to the succession of the plant community. Forest floor and understory plant communities were characterized. Small mammals were collected by Fitch (live) traps and pitfall traps in four age classes during five seasons of study. Fitch live traps and pitfall traps were used in conjunction with one another to obtain the most accurate depiction of the small mammal community. Fitch traps accounted for 65 % of small mammal captures and 7 of 9 species captured. Small mammal abundance and biomass declined with increasing stand …

Habituation, Novelty Response, And Object Differentiation In The Weakly Electric Fish, Brachyhypopomus Pinnacaudatus, Gregory J. Scott

Dissertations and Theses

Weakly electric fish use a combination of active electrolocation and passive mechanosensory receptors for object detection and analysis. When tested with repeated presentations of the same moving object, Brachyhypopomus pinnacaudatus showed a gradual habituation of its electric organ pacemaker acceleration response (novelty response) that was unaltered by changes in the replacement electric organ discharge (S1). When tested with objects of differing velocities, the novelty response of the fish was proportional to the change in velocity of object. The responses of fish to objects that presented different mechanosensory profiles, but equal electrosensory profiles, suggest that the fish used the electrosensory system …

A Half-Century Of Winter Bird Surveys At Lincoln And Scottsbluff, Nebraska, Paul A. Johnsgard

Papers in Ornithology

Since 1900, the National Audubon Society has sponsored annual "Christmas bird counts" during the two-week period encompassing Christmas; and as a result, long-term data on winter bird populations have accumulated, especially for some locations. The first two such counts in Nebraska were made in 1909 and in 1912 in Lincoln. Beginning in 1947 and continuing to the present, an unbroken series of counts were made in Lincoln, usually by members of the Uni¬versity Place Bird Club, the Audubon Naturalist's Club, or the Wachiska chapter of the National Audubon Society. For Scottsbluff, an unbroken set of counts extends from 1949 to …

Evolution And Animal Welfare, Marian Stamp Dawkins

Assessment of Animal Welfare Collection

Animal welfare is a topic often thought to reside outside mainstream biology. The complexity of the methods used to assess welfare (such as health, physiology, immunological state, and behavior) require an understanding of a wide range of biological phenomena. Furthermore, the "welfare" of an animal provides a framework in which a diversity of its responses can be understood as fitness-enhancing mechanisms. Different methods for assessing animal welfare are discussed, with particular emphasis on the role of an animal's own choices and reinforcement mechanisms. No part of biology is as yet able to explain consciousness, but by confronting the possibility that …

Whey Protein Edible Film Structures Determined By Atomic Force Microscope, L.E. Lent, L. S. Vanasupa, P. S. Tong

Dairy Science

Atomic force microscopy was used to study edible films produced from whey proteins. The films were imaged under ambient conditions with no special sample preparation. Low resolution imaging of areas from 10 μm to 150 μm on a side was performed in the contact mode. Higher resolution scans of 350 nm to 2,700 nm required use of the noncontact imaging mode. Features about the same size as the primary protein in whey, beta-lactoglobulin (7 nm), were identified in the film samples. Molecular aggregates in the range of 1 μm, reported in other studies using transmission electron microscopy of whey protein …
