This study evaluated the memory and visual discrimination capabilities of Enteroctopus dofleini, the Giant Pacific Octopus. Octopuses have been known to have advance sensory capabilities and through this study we challenged our specimen to remember and actively choose a specific patterned jar based on a visual pattern and positive reinforcement....
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...

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...
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...
Disturbance has both direct and indirect ramifications that can influence species abundance, distribution, and ultimately the diversity found within a community. As a result, we might expect disturbance to play a particularly important role in the ability of non-native species to proliferate outside of their native range. In practice, disturbance...
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...
