Preliminary research into the relationship between sea otter (Enhydra lutis) foraging and disturbance on eelgrass (Zostera marina) meadows in Morro Bay, California

Abstract:
<p>Eelgrass meadows in Morro Bay are ecologically significant, providing habitat and ecosystem<br>
services such as nutrient cycling, coastal erosion buffering, and carbon flux storage. Sea otter<br>
presence creates a positive feedback within eelgrass meadows through bioturbation, a process<br>
in which organisms disturb sedimentary deposits, thus increasing genetic diversity and allelic<br>
variation as seafloor sediment is modified by otter behavior such as foraging and clamshell<br>
depositing. These occurrences create the foundation for a more productive and diverse<br>
estuarine landscape, promoting the ability for eelgrass to better adapt to changes within its<br>
environment, particularly amidst anthropogenic climate change. Understanding the sea<br>
otter-eelgrass relationship is critical for conservation efforts within the Morro Bay Estuary.<br>
Despite the research being in its initial phases, objectives include identifying knowledge gaps<br>
and establishing a foundation for future research guided by data analysis. At this stage it is also<br>
imperative to conduct a comprehensive review of existing literature regarding sea otters and<br>
eelgrass interactions in analogous ecosystems. Additionally, identifying experts actively<br>
researching eelgrass conditions in Morro Bay is taking place, as well as determining best<br>
practices for data collection.</p>
