Graduate Theses, Dissertations, and Problem Reports
Concern over scale is not new, and it is not restricted to geographers. Spatial and temporal scaling is a conceptual and methodological problem for all sciences using geographic information. This paper teases out issues of scale and ecological fallacy from the literature and discusses how these issues influence the applicability of an influential theoretical framework in stream ecology, the River Continuum Concept (RCC). Investigators are faced with decisions regarding scale during sampling location selection, field data capture, and subsequent data interpretation. A thorough understanding of the heterogeneity of stream habitats and the life histories of the organisms being studied could …

Food Habits Of The Allegheny Woodrat (Neotoma Magister ), Nikole Lee Castleberry
Graduate Theses, Dissertations, and Problem Reports
Regional declines in Allegheny woodrat (Neotoma magister ) populations suggest a better understanding of the ecology of this species is needed for proper management. I described seasonal food habits of the Allegheny woodrat in the Ridge and Valley and Allegheny Plateau physiographic provinces of West Virginia and Virginia using microhistological techniques. In the Allegheny Plateau, the top 5 food items were fungi, blueberries ( Vaccinium spp.), acorns (Quercus spp.), ferns ( Dryopteris spp.), and lichens. In the Ridge and Valley woodrats ate primarily blackberry (Rubus spp.) leaves, fungi, greenbrier (Smilax spp.) leaves, acorns, and oak leaves. Additionally, we examined the …
