In Search of Commonality: Plant communities exhibit a wide variety of responses to global change

Posted December 20, 2021

All plants are somehow affected by global change, but their responses are inconsistent between ecosystems, a LTER Synthesis group finds.

It’s not the plants: nitrogen directly affects alpine soil microbes

Posted December 20, 2021

Can plants dictate how soil microbes respond to nitrogen deposition? New research says no, and sheds light on plant-microbe dynamics.

Pika enthusiasts unite under a common theme

Two new synthesis working groups, awarded in 2021, capitalize on the intensive and extended record of observation at LTER sites to shed light on thorny ecological questions.

From Breeding to Feeding – blue whales are spending more time in Southern California

Posted July 30, 2020

Every year, the Eastern North Pacific population of blue whales migrates between their winter calving grounds off the coast of Mexico and their summer feeding grounds in the California coastal region. Scientists know that they time their migration to coincide with peak prey abundances, but the cues they use for this have been unknown—until now…. Read more »

Started from the Benthos, Now We’re Here—a Holistic Approach to Lake Ecology

Posted May 28, 2020

In 2018, M. Jake Vander Zanden and Yvonne Vadeboncoeur were invited to give a plenary lecture at the International Society for Limnology (SIL) meeting in Nanjing, China. They spoke about their efforts to synthesize a more holistic understanding of the role of benthic productivity and food web pathways in lakes. The two began their journey… Read more »
