Native species in California’s estuaries are expected to experience greater declines as invasive species interact with climate change, according to a study from the University of California, Davis.
The study, published in the Ecological Society of America’s journal, Ecology, said these declines are expected not only because of climate-related stressors, but also because of the expanding influence of new invasive predators whose impacts are occurring much farther up the estuary.
Habitat conservation can help buy time for heat-sensitive species in the face of climate change – but it might also leave them in a trap by preventing them from adapting in time, according to a new study from the UC Davis Bodega Marine Laboratory recently published in the journal Ecology.
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.
Coral reefs are foundational and iconic ecosystems that have long captivated many with their vibrant colors, interesting ecology, and ecosystem productivity. However, these beautiful reefs are facing their biggest challenge yet: climate change. How can immobile marine organisms, such as corals, survive and thrive in waters that are steadily warming? Leslie Guerrero, a PhD student in the Bay Lab at UC Davis, is working tirelessly to answer these questions.
