Renesting - Female's Success After Nesting Failure And The Renesting Of The Dickcissel (Spiza Americana) At Prairie Ridge State Natural Area, Kevin L. Wentworth

Masters Theses

Renesting - Female's success after nesting failure. Many birds are unsuccessful in their first nesting attempt, so renesting is often a very important way for birds to increase their lifetime fitness and for populations to maintain stable numbers. I examined the importance of renesting and the factors that encourage or discourage a female from renesting and also the factors that affect the success of these renests. I also looked for patterns in renesting behavior (e.g., renesting interval, renesting distance, percentage of females that attempt renests, and the success of renests) of birds by comparing different studies. I used a total …

Microsatellite Analysis Of Female Mating Behaviour In Lek-Breeding Sage Grouse, Katy Semple, Robert K. Wayne, Robert M. Gibson

School of Biological Sciences: Faculty Publications

We used microsatellite DNA markers to genotype chicks in 10 broods of lek-breeding sage grouse, Centrocercus urophasianus, whose mothers’ behaviour was studied by radio tracking and observing leks. Previous behavioural studies suggested that almost all matings are performed by territorial males on leks and that multiple mating is rare. Two broods (20%) were sired by more than one male. Genetic analyses of the broods of eight females that visited an intensively studied lek were consistent with behavioural observations. Four females observed mating produced singly sired broods and males other than the individual observed copulating were excluded as sires for most …

The Phylogenetic Relationships Of Lembocarpus And Goyazia (Gesneriaceae) Based On NdhF Sequences, James F. Smith

Biology Faculty Publications and Presentations

The phylogenetic relationships of Goyazia and Lembocarpus are investigated based on cladistic analysis of ndhF sequences. Both genera are currently classified in the tribe Gloxinieae, but both are poorly known. Based on its floral morphology, the classification of Goyazia in Gloxinieae is not controversial. Lembocarpus may be placed in Gloxinieae, Episcieae, or Sinningieae. The acaulescent, tuberous nature of Lembocarpus limits the number of characters available for a morphological analysis and has made its classification and phylogenetic relationships difficult to resolve. Phylogenetic analyses of ndhF sequences place both genera in Gloxinieae. Although the affinities within the tribe are ambiguous …

Measures Of Denitrification In Selected South Dakota Semi-Permanent Prairie Pothole Wetlands, Beverly S. Klein

Electronic Theses and Dissertations

Wetlands are an integral part of agricultural systems in the prairie pothole regions of the North Central United States and Canadian Provinces. Little research has been done on denitrification in prairie potholes, and a better understanding of their denitrifying capability could aide in optimizing management practices near pothole areas. Most probable number (MPN) and denitrifying enzyme activity (DEA or Phase I) assays were conducted. Most probable number (MPN) measures were used to give an estimate of dissimilatory nitrate reduction to ammonia (DNRA) and denitrifying populations present in the wetlands. This study involved 3 selected semi-permanent prairie pothole wetlands near Madison, …

Invertebrate Egg And Plant Seed Banks In Natural, Restored, And Drained Wetlands In The Prairie Pothole Region (Usa) And Potential Effects Of Sedimentation On Recolonization Of Hydrophytes And Aquatic Invertebrates, Robert Andrew Gleason

Electronic Theses and Dissertations

Sediment is the major pollutant of wetlands, lakes, rivers, and estuaries in the United States and it poses unique threats to wetlands of the Prairie Pothole Region (PPR). Sediment may impact the success of wetland restorations because burial of invertebrate and plant propagules may impact hatching and germination success, and hence, may hamper successional changes throughout interannual climate cycles. Sedimentation also reduces the pool depth and volume, further exacerbating the recovery of hydrophyte communities in restored wetlands. I evaluated the potential impacts of sedimentation on prairie wetlands from several perspectives. First, I evaluated the effects of sedimentation on loss of …

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 …

Environmental Analysis Of Cores From The Helike Delta, Gulf Of Corinth, Greece, S. Soter, Patricia Blackwelder, C. Tziavos, D. Katsonopoulou, Terri Hood, Carlos A. Alvarez Zarikian

Marine & Environmental Sciences Faculty Articles

The fan delta southeast of Aigion on the southwest shore of the Gulf of Corinth was the site of ancient Helike, a city destroyed and submerged by an earthquake and seismic sea wave in 373 BC. Bore holes drilled on the Helike Delta yielded numerous ceramic fragments in the upper 12 meters, and a record of changing local environments on the delta during the Holocene period. At about 8 m below present sea level the core profiles show a general upward transition from marine to lacustrine/lagoonalc onditions.T he transition dates from about 8 kyr BP and is probably due to …

Factors Influencing Spatial Variability In Nitrogen Processing In Nitrogen-Saturated Soils, Frank S. Gilliam, Charles C. Somerville, Nikki L. Lyttle, Mary Beth Adams

Biological Sciences Faculty Research

Nitrogen (N) saturation is an environmental concern for forests in the eastern U.S. Although several watersheds of the Fernow Experimental Forest (FEF), West Virginia exhibit symptoms of Nsaturation, many watersheds display a high degree of spatial variability in soil N processing. This study examined the effects of temperature on net N mineralization and nitrification in N-saturatedsoils from FEF, and how these effects varied between high N-processing vs. low N-processingsoils collected from two watersheds, WS3 (fertilized with [NH4]2SO4) and WS4 (untreated control). Samples of forest floor material (O2 horizon) and mineral soil (to a 5-cm depth) were taken from three subplots …

12 | Excavations At Efrata: A Burial Ground From The Intermediate And Middle Bronze Ages, Rivka Gonen

IAA Reports—Monograph Series of the Israel Antiquities Authority

This volume presents the results of the 1979 excavations at the site of Efrata, a hill on the Hebron–Jerusalem road. On the summit is a tumulus, and burial grounds of shaft tombs on the slopes were in use during the Intermediate Bronze Age (IBA) and Middle Bronze Age II (MB II). The hill was apparently an isolated cemetery intensively used by semi-nomadic pastoralists. The shaft tombs were first hewn during IBA, and after a short gap (MB I), reused in MB II. The pottery and small finds are presented, and analysis of the human remains indicates that the burials in …

Predation Risk And Elk-Aspen Foraging Patterns, C.A. White, M.C. Feller

Aspen Bibliography

Elk-aspen foraging patterns may be influenced by cover type, distance from roads or trails, the type of user on road or trail (park visitor, human hunter, or predator), and two general states of aspen condition (open-grown or thicket). Pellet group and browse utilization transects in the Canadian Rockies showed that elk were attracted to roads used by park visitors and avoided by wolves, and that elk possibly avoided aspen and conifer patches near backcountry trails used by wolves. In high predation risk landscapes, aspen stands were dense, lightly browsed, and rarely entered by elk. As risk decreased, elk density and …

Predicting Nest Success From Habitat Features In Aspen Forests Of The Central Rocky Mountains, H.M. Struempf, D.M. Finch, G. Hayward, S. Anderson

Aspen Bibliography

We collected nesting data on bird use of aspen stands in the Routt and Medicine Bow National Forests between 1987 and 1989. We found active nest sites of 28 species of small nongame birds on nine study plots in undisturbed aspen forests. We compared logistic regression models predicting nest success (at least one nestling) from nest-site or stand-level habitat predictors. Most common species used nest sites in aspen trees in forest interior locations (distance to edge >100 m), with dense trees (opening >100 m away) despite no apparent positive correlation with use of these habitat features and nest success rates. …
