Biology of the microsporidan parasite, Pleistophora sp., in three species of Crangonid sand shrimp

Creator:: Breed, Gail Miner
Abstract:: The microsporidan Pleistophora sp. is a common parasite of Crangon franciscorum, C. nigricauda, and C. stylirostris in the vicinity of Yaquina Bay, Oregon. Characteristics of the parasite are described. Skeletal muscle was the only host tissue infected. The seasonal prevalence and intensity of the parasite in crangonids are described, based...

The role of perinatal androgens in the development of neuroendocrine and behavioral characteristics of the gray-tailed vole, Microtus canicaudus

Creator:: Spielvogel, Sandra Petersen
Abstract:: These studies examined the role of perinatal androgen in the development of neuroendocrine and behavioral characteristics of gray-tailed voles, Microtus canicaudus. When mature, females exhibited alternating vaginal smear patterns or persistent vaginal cornification; estrogen and progesterone concentrations were not correlated with vaginal smear patterns. Corpora lutea were not observed in...

Behavior and Ecological Effects of Invasive Lionfish on Atlantic Coral Reefs and Seagrass Beds

Creator:: Benkwitt, Cassandra E.
Abstract:: Although only a minority of introduced species become established and have noticeable consequences in their new communities, some can displace native species, alter food webs, and cause local extinctions. Studying these invasive species can provide new insights into basic ecological questions as well as inform management strategies. Pacific lionfish (Pterois...

Polygyny in the bobolink : habitat quality and the adaptive complex

Creator:: Martin, Stephen George, 1941-
Abstract:: The adaptiveness of polygyny in passerines poses a particularly intriguing problem. The altricial young of this group require extended parental care, but young of polygynous pairings generally lack the undivided attention of the male which young of monogamous pairings receive. Polygynous offspring may thus be undernourished and experience greater mortality....

Resource allocation in four syntopic species of marine diving birds

Creator:: Scott, James Michael, 1941-
Abstract:: During 1969-1971 I studied patterns of resource allocation and behavioral interaction among Brandt's Cormorants, Pelagic Cormorants, Common Murres and Pigeon Guillemots in the area of a breeding colony on Yaquina Head on the central Oregon coast. Extensive studies of the breeding colony were combined with detailed observations of the distribution,...

Ecological relationships of birds in forests of western Oregon

Creator:: Anderson, Stanley H.
Abstract:: The avifaunal composition of ten western Oregon forest stands located at the eastern base of the Coast Range was examined on a seasonal basis. The stands were dominated by Oregon white oak, Douglas fir or western hemlock, Avian populations were sampled monthly from January 1968 to January 1970, using permanent...

Singing behavior of the Bewick's wren : development, dialects, population structure, and geographical variation

Creator:: Kroodsma, Donald E.
Abstract:: The songs of the Bewick's Wren are discrete units of one to three seconds duration with intersong intervals several times the length of the song. Individual song repertoires at the William Finley National Wildlife Refuge, Oregon, range from 13 to 20 song types, and a given song type is repeated...

Behavioral patterns and their temporal organization in breeding American Avocets

Creator:: Gibson, Flash
Abstract:: The organization of behavioral activities in time is important to a bird's survival and reproduction. To be successful, either proximately or ultimately, a bird must apportion its behavior in time so that it may obtain sufficient energy for maintenance activities and for such activities as migration and reproduction. The organization...

Invasive Pacific Lionfish Alters Native Community Interactions on Atlantic Coral Reefs

Creator:: Kindinger, Tye L.
Abstract:: Biological invasions have been identified as one of the prominent drivers of global environmental change. In particular, invasive predators typically have substantial negative effects on populations of native prey, even driving species to extinction in extreme cases. However, beyond direct predatory effects, little is understood regarding the specific mechanisms by...
