Parking under a bridge, I walked down a short dirt road to the cutgrass (Zizaniopsis miliacea) marsh. The bright green stalks waved overhead, completely immersing me as I stepped onto a narrow boardwalk that provides access to the gridded plots. The air was hot and humid, t-shirts and shorts sticking to arms and legs as students and researchers moved amid the marsh.
Every month, Field Technician Tim Montgomery loads his equipment onto a center console motorboat and heads off into the marshes surrounding Sapelo Island, Georgia. Over the course of several hours, he stops at multiple sites to check on the Georgia Coastal Ecosystem LTER network of data loggers continually collecting water quality parameters as they gently bob in the water. On one particular morning, I had the opportunity to go with him.

The connections between humans and oceans run deep. Kelp forests, plankton, estuaries, and coral reefs support robust and diverse food webs, feeding both body and spirit. The destructive effects of big storms are tempered by marshes and mangroves—sometimes to their benefit and sometimes their detriment. Currents, migrations, climate, and nutrients connect ecosystems and the… Read more »
Relying on a 114 year-long data set, researchers from the Sevilleta LTER have developed a more accurate way to model climate sensitivity functions that describe the relationship between ecological variability and plant productivity, rather than focusing on linear relationships between ecosystem response and average climate trends, as is more typical. While variances in factors such as… Read more »
Hurricanes are typically considered destructive and disastrous, with high-speed winds exceeding 75 miles per hour and torrential downpours. These powerful storms can have major impacts on tropical forests, ripping open the forest canopy and causing organic debris to pile up on the forest floor. Despite these seemingly destructive qualities, new research suggests that ecological disturbance… Read more »
Kelp forests have long been known to harbor a high number and diversity of marine species, from tiny crustaceans to large fish and marine mammals. This biodiversity tends to be attributed to the complex structure and productivity of giant kelp, earning it the title ‘foundational species’. Surprisingly, however, little quantitative data has been assessed to… Read more »
In ecology, timing is key to understanding how daily, seasonal, or yearly cycles impact environmental processes. But it’s not just about how often impacts occur, but also over what length of time. Decades worth of data synthesized by researchers at Coweeta LTER provide some of the clearest evidence to date that long-term observations of ecosystem… Read more »
For those living in South Florida, sea level rise is a very real problem that’s impacting coastal areas right now, and is expected to worsen over the next decade. While most discussions on sea level rise in Florida focus on highly populated coastal cities such as Miami and Tampa, sea level rise is also having… Read more »
