Fires and floods are becoming all too common for coastal Southern California residents — but are these ‘extreme’ events likely to become even more frequent? Answering this question requires a comprehensive understanding of precipitation patterns in the region and how they are likely to change in the coming decades. Most previous research on climate change… Read more »

2018 ESA Annual Meeting Presentations In the past year alone, extreme events including hurricanes, droughts, and extensive fires have impacted significant regions of the United States—affecting the health of both natural habitats and human communities. Fittingly, the theme of this year’s Ecological Society of America (ESA) annual meeting is ‘Extreme events, resilience and human well-being.’… Read more »
On the boundaries of fresh and saltwater systems, coastal marshes give rise to diverse, productive ecosystems that act as carbon sinks. Their secret? Freshwater marsh plants receive just the right amount of nutrients and salt from periodic seawater tides to thrive. However, incursions of saltwater into these systems are increasing —often caused by drought and… Read more »
Observed benefits of carbon dioxide enrichment to C3 v. C4 plants appear to reverse after 12 years of treatment.
The Yahara may sound like the name of a vast desert, but it’s actually a 359-square mile watershed in southern Wisconsin. The Yahara Watershed is a mix of urbanized land (including the state capital), productive agriculture land, and a chain of lakes called the Yahara Lakes. Because of its diverse environment, the Yahara provides many… Read more »
Climate change is already impacting polar habitats such as the Arctic tundra, where increasing temperatures are causing permafrost to thaw and exposing soil and organic matter that have been buried for thousands of years. Many scientists predicted that this soil, once exposed, would release a massive amount of sequestered carbon into the atmosphere, contributing to… Read more »
