Katie Dobkowski – Marine Ecology
As global conditions change, nearshore marine environments are also shifting, forcing organisms to alter where or how they live in response to fluctuations in ocean chemistry and temperature. Understanding changes in distribution and abundance is especially important for foundation species, such as seaweed or seagrass, as well as benthic organisms that occupy space and create habitat. My research uses a combination of field and laboratory experiments to examine how species interactions influence nearshore environments (Dobkowski 2017; Dobkowski et al. in revision); I seek to facilitate undergraduate involvement in research by allowing students to ask their own questions under a broader project goal.
Global climate change is likely to influence not only abiotic conditions in the oceans, such as pH, temperature, and salinity, but also species distribution, abundance, and interactions. While research on the effect of single stressors provides a good starting point, evidence suggests that understanding the influence of multiple stressors will provide greater insight into how species will respond to future climate change.
The questions I will address are:
1. How do multiple stressors influence successful life stage transitions in sugar kelp (Saccharina latissima)?
2. How has recruitment and persistence of intertidal organisms changed with shifting environmental conditions?
