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...
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...
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...
The study related the density of herbivores to the length and density of Prionitis spp. in Oregon’s coastal tidepools. Oregon’s coastal rocky intertidal tidepools contain a variety of species interactions, including algal grazing by herbivores. The red branched algae Prionitis spp. is found throughout the rocky intertidal in the low...
Ocean acidification is negatively impacting organisms that use calcium carbonate to form their shells. Increasing OA conditions are putting a strain on these calcareous animals by weakening their shells, thus causing them to become more vulnerable to predation. Worsening shell integrity may lead to a decline in hard-shelled prey populations...
Ocean acidification is caused by the dissolved carbon dioxide in the oceans lowering the amount of free carbonate ions. This is turn, affects the ability of calcifying organisms like mussels to build thick shells to protect against predation. Mussels are often preyed upon by both specialist crabs, like Red Rock...
Writing within Discipline is a pedagogical model that aims to engage students in active learning and to develop critical thinking and writing skills within the norms of a particular discipline. However, lack of faculty time for grading writing products impedes its broader implementation. Web based peer review programs have been...
