The predation of mudflat burrowing shrimp by native Oregon crabs Red rock crab (Cancer productus) and Dungeness crab (Cancer magister) versus an invasive crab European green crab (Carcius maenas)

Creator:: Trobaugh, Sean A.
Abstract:: Yaquina Bay, Oregon, has been introduced to a few The invasive species in Yaquina Bay, Oregon can have a huge effect on the native species and local ecosystem. European green crab (Carcius maenas) is an invasive species. The European green crab can be found on the mudflats competing with the...

Detecting changes in whelk abundance using hermit crab shell utilization in Oregon's rocky marine intertidal

Creator:: Van Orman, Bryan G.
Abstract:: Utilization and preference of whelk shells by the hairy hermit crab are examined in the following to further define the ecology of Oregon’s mid to low intertidal ecosystems. The study was conducted at Tokatee Kloochman State Natural Area (TK) where I made observations before collecting data. My observations were of...

Coralline and fleshy algae volume density on epifaunal communities

Creator:: Field, Samuel J. and Gani, Christopher D.
Abstract:: Carbon dioxide emissions greatly affect the carbon chemistry mechanisms within the ocean. Carbon absorbed by the ocean, drops the pH level and creates an environment that is acidic. Acidic conditions prevent calcification mechanisms in coralline algae, and hinder their ability to establish within the intertidal. Coralline algae display structural relevance...

Spatial and vertical distribution of the invasive European green crab, Carcinus maenas, in a temperate estuarine system

Creator:: Lundeberg, Christopher A. and Weldon, Taylor
Abstract:: Carcinus maenas is an invasive marine predator. Its generalist feeding strategies make it one of the most effective invaders. Carcinus maenas has invasive populations throughout the world, and was recently introduced to the west coast of North America. This study looks at the abundance and growth of C. maenas in...

Spatial and vertical distribution of the invasive European green crab in a temperate estuarine system

Creator:: Lundeberg, Christopher A. and Weldon, Taylor
Abstract:: The European green crab, Carcinus maenas, is a generalist predator that has established invasive populations throughout the world, including the west coast of North America. In Oregon, strong cohorts of green crabs recruit only during major El Niño events. The goals of this study are to: 1) compare the abundance...

Effects of tide pool size and elevation on purple sea urchin abundance and reproductive health

Creator:: Kraus, Kailey and Peven, Skylar
Resource Type:: Presentation

Site and Light: Looking at factors that affect the growth rate of Saccharina sessilis

Creator:: Beem, Kristin, Meltvedt, Ariana, and Carsh, Alexander
Abstract:: Saccharina sessilis, lettuce kelp, is a macroalgae that contributes to the primary production in the intertidal zone off of the Oregon Coast. Macroalgae can serve as a bioindicator of increased nutrient input, water quality, and shifts in the intertidal environment. Competition for light exists between macroalgae species and with other...

Prey preference of Pisaster ochraceus and Leptasterias hexactis recruits of the rocky intertidal along the central Oregon coast

Creator:: Vercruyssen, Anna, Minten, Aubree, and Blacketor, Katie
Abstract:: Sea stars are well known on the Pacific coast as being keystone species. Pisaster ochraceus plays a major role in controlling the lower limits of the high zone mussel beds, normally preying on medium to large-sized species. Leptasterias hexactis is often found feeding on smaller prey. According to the competitive...

Comparing Metacarcinus magister settlement preferences among the seagrasses Zostera marina and Zostera japonica

Creator:: Heidmann, Sarah and Jaco, Erin
Abstract:: Metacarcinus magister, the Dungeness crab, is a commercially important species on the Pacific Northwest coast as the most profitable fishery in Oregon and an important ecological player as both predator and prey. Understanding the spatial distribution of Dungeness throughout different life history stages is beneficial both ecologically and economically. Zostera...
