The Effects of Stress on Fish: Environmental Physiology

 

If you’ve ever had the chance to explore a rocky intertidal ecosystem, you may have noticed quickly that all of the “cool,” colorful critters tend to reside in the deeper pool areas that are underwater, even when the surrounding rocks are exposed to the air. When many people go “tidepooling,” they are usually interested in exploring these pools because there typically resides a greater diversity of species. But have you ever wondered why it is that more species live in those pools than on the bare rocks? Or why some species can survive on the bare rocks while others seemingly cannot?

Uncovering the Ecological Network in Bodega Bay

Stepping out onto the rocky shore of Bodega Bay, you would quickly notice that the intertidal zone is teeming with life. From mussels and barnacles to crabs and anemones, hundreds of species occupy these rocky areas - experts Jackie Sones and Dr. Eric Sanford estimate that there are about 250 different species that make their homes in this rocky intertidal zone in Bodega Bay!

Critically endangered sea star not recovering in the wild, scientists point to the need for restoration efforts

New research documenting the population crash of the iconic sunflower sea star (Pycnopodia helianthoides), and complete absence of population recovery since the 2013 outbreak of the marine wildlife epidemic sea star wasting disease, was published today in the prestigious journal Proceedings of the Royal Society B. The study calls for new strategies for protecting species impacted by increasingly frequent marine epidemics associated with changing ocean conditions.

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.

Ecosystem-based Management of Forage Fish Could Benefit Ocean and Communities

Taking a holistic, ecosystem-based approach to managing small prey species known as forage fish could yield several economic and ecological benefits, a new study has found. The research, which focused on forage fisheries off the coast of California, modeled a management strategy for two forage fish species—anchovy and sardine—while also considering populations of halibut and brown pelicans, both of which feed upon forage fish.
