Sea otters have long been recognized as a classic example of a keystone species, a dominant predator that maintains the balance of kelp forest ecosystems by controlling populations of sea urchins, whi...
Satellite imagery shows that the area covered by kelp forests off the coast of Northern California has dropped by more than 95%, with just a few small, isolated patches of the bull kelp remaining. Spe...
The researchers replicated the formation of these natural structures by creating sugar-based pinnacles, mimicking the soluble rocks that compose karst and similar topographies, then submerging them in...
Stone forests -- pointed rock formations that resemble trees -- populate regions of China, Madagascar, and many other locations worldwide. They are as majestic as they are mysterious, created by uncer...
A forest's ability to store carbon depends on the bedrock beneath, according to Penn State researchers who studied forest productivity and composition and the physical characteristics of roc...
Tropical forests contain some of the most biodiverse and dynamic ecosystems in the world.The influence of precipitation, temperature, and soils is especially noticeable when comparing the towering tre...
The destructive power of a hurricane appears to be good news for mangroves in the Florida Everglades.When Category 3 hurricanes Wilma (2005) and Irma (2017) struck Florida, mangroves took a beating, e...
