Morphology, Sediment Microbial Analysis, and Species Distribution Modeling of a New Offshore Population of Ghost Shrimp (Neotrypaea sp.)

Creator:: Hardisty, Sarah
Abstract:: In 2019, a multi-cohort population of the typically estuarine burrowing shrimp Neotrypaea sp., was discovered approximately 7 miles offshore of Newport, Oregon. Morphological analysis of the offshore population, microbial sediment sequencing, and species distribution modeling was conducted with this new offshore population. In order to identify Neotrypaea sp. to the...

From Pepper to the Philippines: American Experiences in Southeast Asia, 1784 - 1898

Creator:: Baer, Adela S., 1931-
Abstract:: Since Americans were a minority among the outsiders in Southeast Asia before the twentieth century, a legitimate question is: Why write about them there? There are three sides to the answer. For one, there has been no general account of Americans in nineteenth-century Southeast Asia.¹ In addition, the mistakes of...

Alarista succina gen. et sp. nov. (Poaceae: Bambusoideae) in Dominican amber

Creator:: Poinar, George, Jr. and Columbus, J. Travis
Abstract:: Alarista succina gen. et sp. nov. (Poaceae) is described from a single floret preserved in amber of Tertiary age originating from the Dominican Republic. The new genus is characterized by 1) a narrow winged lemma awn, 2) numerous (as many as 17) lemma nerves, 3) a lengthy rachilla internode (implying...

Rapid onset of mate-quality assessment via chemical signals in a woodland salamander (Plethodon cinereus)

Creator:: Chouinard, Adam J.
Abstract:: In the competition to acquire mates, environmental factors can be important in determining the relative quality of an individual. These aspects of quality are often conveyed through signals used for mate assessment by the most energetically-invested sex. In red-backed salamanders, Plethodon cinereus, chemical signals communicate a surprising amount of information,...

Effects of invasive Pacific red lionfish Pterois volitans vs. a native predator on Bahamian coral-reef fish communities

Creator:: Albins, Mark A.
Abstract:: The recent irruption of Pacific red lionfish (Pterois volitans) on Caribbean and Atlantic coral reefs could prove to be one of the most damaging marine invasions to date. Invasive lionfish are reaching densities much higher than those reported from their native range, and they have a strong negative effect on...

Offspring of first-generation hatchery steelhead trout (Oncorhynchus mykiss) grow faster in the hatchery than offspring of wild fish, but survive worse in the wild: Possible mechanisms for inadvertent domestication and fitness loss in hatchery salmon

Creator:: Blouin, Michael S., Wrey, Madeleine C., Bollmann, Stephanie R., Skaar, James C., Twibell, Ronald G., and Fuentes, Claudio
Abstract:: Salmonid fish raised in hatcheries often have lower fitness (number of returning adult offspring) than wild fish when both spawn in the wild. Body size at release from hatcheries is positively correlated with survival at sea. So one explanation for reduced fitness is that hatcheries inadvertently select for trait values...

Linking removal targets to the ecological effects of invaders: a predictive model and field test

Creator:: Green, Stephanie J., Dulvy, Nicholas K., Brooks, Annabelle L. M., Akins, John L., Cooper, Andrew B., Miller, Skylar, and Côté, Isabelle M.
Abstract:: Species invasions have a range of negative effects on recipient ecosystems, and many occur at a scale and magnitude that preclude complete eradication. When complete extirpation is unlikely with available management resources, an effective strategy may be to suppress invasive populations below levels predicted to cause undesirable ecological change. We...

Weevils That Live Under Trees Thrown Out of the Sea: Phylogeny and Microbial Diversity of Sthereus Motschulsky, 1845 and Related Weevils (Curculionidae: Molytinae)

Creator:: Young, Natasha
Abstract:: Here the diversity and phylogeny of the genus, Sthereus Motschulsky, 1845, and its nearest associates in the large subfamily Molytinae are explored through molecular and morphological characters. Sanger sequencing of five genes determined that Sthereus is not monophyletic. Instead, the one species in the genus Gastrotaphrus Buchanan 1936, G. barberi...

Modifications to Rearing Environments as a Method for Reducing Domestication Selection in Hatchery-reared Steelhead (Oncorhynchus mykiss)

Creator:: Obley, Miriam
Abstract:: Since the decline of salmonid populations in the Pacific Northwest, supplementation programs have become frequently implemented by hatcheries as a way to protect and conserve wild stock. However, hatchery-reared fish have lower fitness than wild fish which is likely due to adaptation to the hatchery environment, i.e., domestication selection. Fish...
