Stressful childhoods can affect an individual’s adult years and influence future generations. Scientists at the University of California, Davis, found a similar pattern holds true for red abalone exposed as babies, and again as adults, to the stress of ocean acidification.
White abalone shells are magnificent structures. Translucent during the marine snail’s juvenile days, the extremely durable shell increases in opacity as the organism ages, gaining its paint-splatter-esque red, brown and white coloring from the algae it eats.
All seven of the United States’ abalone species that live on the West Coast are listed as Critically Endangered or Endangered according to the International Union for Conservation of Nature, or IUCN, Red List of Threatened Species. This is the first global Red List assessment of the species. The West Coast listings were based on an abalones assessment led by Laura-Rogers Bennett of the California Department of Fish and Wildlife, or CDFW, and University of California, Davis.

The world’s abalone are threatened, endangered or otherwise vulnerable in nearly every corner of the planet. While captive breeding efforts are underway for some species, these giant sea snails are notoriously difficult to spawn. If only we could wave a magic wand to know when abalone are ready to reproduce, without even touching them.
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.
The flashlight illuminates tens of thousands of swirling, floating specks, each no bigger than a breadcrumb. Raising my voice to be heard over the low roar of machinery in the wet lab, I ask Dr.
