Event Title
Zooplankton abundance, diversity, and distribution in San Juan Channel during autumn 2015
Presentation Abstract
The purpose of this project was to record zooplankton abundance, distribution and diversity at two different study sites in the San Juan Channel during the autumn of 2015, while continuing an annual, long-running dataset. Previous projects have also focused on factors associated with distribution patterns, such as tides and tidal current speed . A possible relationships between dissolved oxygen and the density of certain taxa were tested via linear regression analyses within autumn 2015 and over preceding years of data collection. Both inter-annual and intra-seasonal temporal changes in abundance and distribution were observed during autumn 2015, some of which were consistent with other years. While diversity was consistent, the community assemblages at the two sites varied. Dissolved oxygen was seen as a factor co-varying with abundance of certain taxa. Caridean shrimp and gastropod larvae had positive relationships (p=0.008 and p=0.014) and polychaete trochophores had a negative relationship (p=0.018). However, these relationships did not all hold across the years.
