SPECIAL SEMINAR: Margaret Daly's PhD Dissertation Defense: Oceanography in Kelp Forest Environments and Applications to Policy

Sponsored by

This event is over.

Event Details:

The increasing frequency of extreme events threatens marine ecosystems and important fisheries. In recent years, coastal fisheries have collapsed from elevated stressors such as hyperthermia (increased temperature), hypoxia (decreased dissolved oxygen), and acidification (decreased pH), leading to severe economic loss and shifts in ecosystem functions. In kelp forests, which are three-dimensional complex systems, variability can generate microclimates and potential safe spaces for benthic organisms during these events.
This dissertation addresses the changes in warming, hypoxic, and multiple stressor events at two sites in kelp forests (M. pyrifera) around Isla Natividad, Baja California Sur, from 2013 - 2020 and the specific applications to the management of green abalone (H. fulgens). We also explore the hydrodynamics at multiple sites around the island and how the presence of kelp and coastal geometry can affect the dispersal radius and transport of larvae.
