Foraging ecology of pollinators in the early stages of secondary succession in the western hemlock (Tsuga heteropohylla (Raf.) Sarg.) zone of the Oregon Coast Range

Creator:: Burikam, Intawat
Abstract:: The early stages of secondary succession of the McDonald and Paul Dunn State Forests, Corvallis, Oregon, were grouped into three stages; herb, herb-shrub, and shrub, based on vegetation types. Flowers of herbaceous species and residual shrubs dominated in the early years after clear-cutting. Woody plants became increasing abundant in the...

Aspects of the bionomics of the parasitic honey bee brood mite, Varroa jacobsoni Oudemans

Creator:: Principal de D'Aubeterre, Judith
Abstract:: Aspects concerning the bionomics of the parasitic honey bee brood mite, Varroa jacobsoni Oudemans were investigated. Mite mortality is great during the winter season when the host colony is not rearing brood, appearing to be independent of the mortality of its host. In winter period, no significant association between the...

Scent-making by nectar collecting honey bees

Creator:: Wetherwax, Peter B.
Abstract:: Honey bees mark artificial flowers with scents that advertise about the previous history of the flower to subsequent foragers. Unrewarding flowers are marked with a scent, after a single visit, that makes the flower less attractive to subsequent foragers. Previously rewarding flowers are initially less attractive than unvisited flowers but...

The role of body size in the foraging strategies and management of avian herbivores : a comparison of dusky Canada geese (Branta canadensis occidentalis) and cackling geese (B. hutchinsii minima) wintering in the Willamette Valley of Oregon

Creator:: Mini, Anne E.
Abstract:: Body size explains much of the interspecific variation in the physiology, behavior, and morphology of birds, such as metabolic rate, diet selection, intake rate, gut size, and bill size. Based on mass-specific metabolic requirements and relative energetic costs of activities, being a certain body size has both advantages and disadvantages....

Transcriptional regulation of the human cathelicidin antimicrobial peptide gene

Creator:: Guo, Chunxiao
Abstract:: Human cathelicidin antimicrobial peptide (CAMP/LL-37) is a cationic antimicrobial peptide that is widely expressed by myeloid and epithelial cells at the human-environment interface. It possesses broad spectrum antimicrobial capacity against bacteria, fungi and viruses. In addition to its direct antimicrobial activity, CAMP/LL-37 also attracts and recruits monocytes, neutrophils and other...

Pheromone-mediated behavior of adult Douglas-fir tussock moths, Orgyia pseudotsugata (McD.) (Lepidoptera: Lymantriidae)

Creator:: Swaby, James Archie
Abstract:: The sinuous flight behavior of male Douglas-fir tussock moths, Orgyia pseudotsugata, (McD.), is characterized by positive anemotaxis and positive chemoklinotaxis and varies depending on distance from the pheromone source, population density, and time of day. Visual cues play a minor role in close-range orientation to a pheromone source, but males...

Epidemiological implications of sporozoite aggregation in malaria vectors

Creator:: Li, Xiaohong, 1963-
Abstract:: This study describes and quantifies some microprocesses of malaria transmission including blood vessel location by Anopheles stephensi and sporozoites delivery of An. stephensi infected by Plasmodium berghei. The study models the effects of malaria parasite-induced changes in probing behavior and mosquito mortality on disease transmisson. Finally, host, vector, and parasitological...
