How Toxic is the Water’s Surface on Florida’s Indian River Lagoon?
Florida Atlantic University

Specific health effects of toxins on the water surface of the Indian River Lagoon are not fully understood. Scientists collected water samples during the 2018 wet and 2019 dry seasons and analyzed them. Results showed that concentrations of Microcystis aeruginosa, harmful algal blooms, and saxitoxin, a neurotoxin, were both generally higher during the wet season. Microcystins, produced by blue-green algae, were present only under specific environmental conditions.

Climate Change Is Driving Plant Die-Offs In Southern California, UCI Study Finds
University of California, Irvine

Irvine, Calif., June 21, 2021 – A shift is happening in Southern California, and this time it has nothing to do with earthquakes. According to a new study by scientists at the University of California, Irvine, climate change is altering the number of plants populating the region’s deserts and mountains. Using data from the Landsat satellite mission and focusing on an area of nearly 5,000 square miles surrounding Anza-Borrego Desert State Park, the research team found that between 1984 and 2017, vegetation cover in desert ecosystems decreased overall by about 35 percent, with mountains seeing a 13 percent vegetation decline.

Researchers Reveal Complex Ecosystem Changes Cause More Greenhouse Gases To Be Emitted From Peatlands

Peatlands, which make up 3 percent of Earth’s total land area, are known by a number of names — moors, mires, bogs, swamps and portions of permafrost tundra. They also store a significant amount of the Earth’s carbon. A research team from Florida State University and Georgia Institute of Technology are paying close attention to these complicated systems because they’ve found that the warming Earth is stimulating complex ecosystem changes with the end result of even more greenhouse gases being released into the air.

A study of woodland ecosystems that provide habitat for rare and endangered species along streams and rivers throughout California reveals that some of these ecologically important areas are inadvertently benefitting from water that humans are diverting for their own needs. Though it seems a short-term boon to these ecosystems, the artificial supply creates an unintended dependence on its bounty, threatens the long-term survival of natural communities and spotlights the need for changes in the way water is managed across the state.
