Hidden dynamics : community ecology and costs of parasite infection in African buffalo (Syncerus caffer)

Creator:: Henrichs, Brian
Abstract:: Most wild animals are concurrently infected with multiple parasite species for most of their lives. These parasite species assemble into rich and diverse communities, with parasites using host tissues for growth and reproduction as well as evolving strategies to evade the host immune system. The net effect of these ecological...

Community Ecology of Foliar Fungi and Oomycetes of Pseudotsuga menziesii on the Pacific Northwest Coast

Creator:: Gonen, Lilah
Abstract:: Pseudotsuga menziesii var. menziesii (coast Douglas-fir) is a tree of ecological, economic, and cultural value in its native North American Pacific Northwest (PNW) distribution. P. menziesii is host to a variety of well-documented endophytic foliar microorganisms, including the fungus Nothophaeocryptopus gaeumannii, the causal agent of Swiss needle cast (SNC), and...

Population and community ecology of the red alga Rhodomela larix (Turner) C. Agardh, on the central Oregon coast

Creator:: D'Antonio, Carla Marie, 1956-
Abstract:: Aspects of the life history and ecology of the intertidal turf-forming alga Rhodomela larix (Turner) C. Agardh were examined over a two year period at several sites on the Oregon coast. Rhodomela occurred over a broad tidal range and exhibited different growth and morphology characteristics with respect to tidal height....

Effects of plant community characteristics on insect abundance : implications for sage-grouse brood-rearing habitat

Creator:: Ersch, Erica A.
Abstract:: A causative factor in declining greater sage-grouse (Centrocercus urophasianus) populations is reduced annual recruitment due to poor habitat quality. Sage-grouse population decline is concurrent with a decline in the extent and quality of the sagebrush (Artemisia sp.) biome. However, current research has shown a positive relationship between sage-grouse brood and...

Prescribed fire effects on vegetation and arthropod dynamics, and sampling techniques in a Wyoming big sagebrush community

Creator:: Rhodes, Edward C.
Abstract:: In the western United States, sagebrush (Artemisia spp L.) dominated rangelands are extensive, accounting for approximately 63 million ha. The Wyoming big sagebrush (Artemisia tridentata Nutt. ssp. wyomingensis Beetle & Young) alliance is found in more xeric environments, occupying the largest area of the big sagebrush complex in areas within...

Grazing Effects on Fuels and Plant Community Characteristics across Three Community Types in Wyoming Big Sagebrush Steppe

Creator:: Thomas, Tyler W.
Abstract:: Livestock grazing is the prominent land use in Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) steppe and has been present since the late 1800’s. There have been calls to remove livestock grazing from rangelands as historic grazing practices resulted in the degradation of some...

Ecological effects of spring and fall prescribed burning on basin big sagebrush : Idaho fescue--bluebunch wheatgrass communities

Creator:: Sapsis, David B.
Abstract:: The vegetation response of spring and fall prescribed fires in basin big sagebrush (Artemisia tridentata subsp. tridentata Nutt.)/Idaho fescue (Festuca idahoensis Elmer)--bluebunch wheatgrass (Agropyron spicatum Pursh. (Scribn. & Smith)) communities was measured at the John Day Fossil Beds National Monument in eastern Oregon. Objectives of the study were to quantify...

Planning for the Future Forest on the Northern Shawangunk Ridge: Climate-Adaptive Disturbance Preparedness and Response Recommendations

Creator:: Randazzo, Andrew
Abstract:: Mohonk Preserve intends to manage their forestland more actively with the mission of promoting forest health, climate-adaptation, and overall ecosystem health for the benefit of their community and recreational users. Climate-adaptive management recommendations (recommendations that address climate change vulnerabilities —by promoting either resistance, resilience, or transition— while helping to meet...

Forb Community Response to Various Disturbances in the Pacific Northwest Bunchgrass Prairie

Creator:: Watson, Brogan L.
Abstract:: Observed declines in native pollinator species worldwide has generated concern and focused research into the disturbances, past and present, which may have contributed to these losses. In grasslands, for example, habitat degradation and fragmentation from historical and current crop production and livestock grazing has left only a few remnants of...

Nutritional characteristics of dormant season grazing within a winterfat (Krascheninnikovia lanata (Gueldenstaedt)) dominated plant community, and the effect of seedbed preparation on the emergence and survival of winterfat and squirreltail (Elymus elymoides (Raf.) Swezey) seedlings

Creator:: Estes, Mark G.
Abstract:: The effect of seedbed preparation on the emergence and survival of winterfat (Krascheninnikovia lanata (Gueldenstaedt)) and squirreltail (Elymus elymoides (Raf.) Swezey)) seedlings was determined, while quantifying nutritional changes through the dormant season for four range species. In November of 2004 twenty 9m x 8m plots were randomly prepared with one...
