Reconstructing the paleobiology of the dinosaurs

Creator:: Geist, Nicholas R.
Abstract:: Dinosaurs represent one of the most successful evolutionary radiations of terrestrial vertebrates, with a myriad of forms that dominated the terrestrial environment for over 180 million years. Despite the fact that dinosaurs are the focus of extensive popular and scholarly investigation, relatively little is actually known of their biology. The...

Osmotic and ionic regulation in the Dungeness crab, Cancer magister (Dana)

Creator:: Alspach, George Samuel, Jr.
Abstract:: Osmotic and ionic regulation was studied in the Dungeness crab, Cancer magister, after acute exposure to a range of five salinities from 25% to 125% sea water (100% = 32%). Blood, urine and muscle tissue were sampled at 24 and 48 hours after exposure. Analyses were made of blood and...

The morphology and ecology of Echinorhynchus lageniformis Ekbaum, 1938 (Acanthocephala)

Creator:: Barnes, James R.
Abstract:: The acanthocephalan Echinorhynchus lageniformis Ekbaum, 1938, is a common intestinal parasite of the starry flounder, Platichthys stellatus (Pallas), of Yaquina Bay, Lincoln Co., Oregon. Three hundred and sixty-one flounders were examined and 146 (40.5 percent) were found to harbor infections of E. lageniformis. Cystacanths of E. lageniformis were found encysted...

The life history of Neoechinorhynchus rutili (Mueller, 1780) and its development in the intermediate host (Acanthocephala ; Neoechinorhychidae)

Creator:: Merritt, Sheridan Vernon
Abstract:: The fish of Suttle Lake, Oregon, have been found to harbor an acanthocephalan parasite, which lives attached to the mucosa of the intestine. Between July 1961 and January 1963, several hundred of these fish were exarnined and nearly every one was infected with this parasite, which was identified as Neochinorhynchus...

Investigating variation in immunity and infection risk in wild ungulates

Creator:: Dugovich, Brian S.
Abstract:: In the midst of the sixth mass extinction, understanding wildlife disease spillover is critical to maintaining protected wildlife areas. Studying ecoimmunology and wildlife disease ecology helps to understand immune and disease traits in an ecological context, which is invaluable in preventing pathogen spillover between livestock and wildlife. To investigate this...
