Climate Change: Grief, Anxiety, Joy, and Art

This article is a guest post by Ashley Smart, a Ph.D. candidate at UC Davis, and a recipient of the 2020-2021 Bilinski Fellowships at Bodega Marine Laboratory.

Survivors of Climate Driven Abalone Mass Mortality Exhibit Declines in Health and Reproduction Following Kelp Forest Collapse

Marine ecosystems are vulnerable to climate driven events such as marine heatwaves yet we have a poor understanding of whether they will collapse or recover. Kelp forests are known to be susceptible, and there has been a rise in sea urchin barrens around the world. When temperatures increase so do physiological demands while food resources decline, tightening metabolic constraints. In this case study, we examine red abalone (Haliotis rufescens) looking at sublethal impacts and their prospects for recovery within kelp forests that have shifted to sea urchin barrens.

Climate Justice Seminar Recap: Dr. Hilda Lloréns

On May 3, 2021, the UC Davis Coastal & Marine Sciences Institute hosted Dr. Hilda Lloréns, an Associate Professor at the University of Rhode Island and an author of multiple books. Dr. Lloréns is a cultural anthropologist and de-colonial scholar whose research is centered on how racial and gender inequality manifests itself in access to environmental resources and exposure to environmental degradation.

Climate Justice Seminar Recap: Dr. Mustafa Santiago Ali

On April 5, 2021, the UC Davis Coastal & Marine Sciences Institute hosted a conversation with Dr. Mustafa Santiago Ali, facilitated by Dr. Liz Whiteman. Dr. Mustafa Santiago Ali is a giant in the field of environmental justice, and has spearheaded and served on many different roles throughout his career to uplift communities affected by social and environmental injustices. Dr. Ali’s career includes time as a Brookings Institution Congressional Fellow and 24 years at the US Environmental Protection Agency (EPA).

Geographical and environmental impacts on symbiotic relationships between anemone and algae

Corals and anemones form a symbiotic partnership with photosynthetic algae based on an exchange of nutrients: the host receives sugar from the algae, the algae receives nutrients and consistent exposure to sunlight from the host. This relationship can break down under stressful conditions, a phenomenon known as 'bleaching,' which, in the case of tropical corals, can quickly lead to the death of the host. Bleaching resistance can arise if a local population consistently encounters and adapts to warmer conditions.

Long Term Impacts of Marine Heatwave on Kelp Forests

A new study led by researchers at UC Santa Cruz, with coauthors from UC Berkeley, UCLA, UC Santa Barbara, and UC Davis, documents the collapse of kelp forest ecosystems off the coast of Northern California. Analyzing the contributing events, from warming oceans to the loss of sunflower sea stars, researchers used satellite imagery from over 30 years to assess historical changes and better understand the dynamics and resilience of kelp forests.
