This session seeks to bring together LTER researchers interested in understanding how environmental change across timescales is altering the production and transfer of organic matter from primary producers to herbivores. Any ecosystem on Earth is subject to temporal variations in biological production and consumption over broad time scales (from diel to decadal) in response to changes in the environment and to disturbances. Understanding the flow of C and energy from primary producers to their consumers provides essential information about ecosystem properties and functions. Both terrestrial and aquatic ecologists have long been assessing ecosystem primary production and the amount of autotrophic C transferred to higher trophic levels, irrespective of how challenging it is to assess these transfer rates. Together we will synthesize the current status and identify future needs to establish a mechanistic and predictive understanding of the trophic interactions from primary producers to their consumers.

6 presenters will share their story about their LTER sites, including marine, lake and terrestral ecosystems, during the first hour.

The last 30 min will be dedicated to a participatory and inclusive discussion.

As part of the NES-LTER project, I’m investigating the dynamics of the planktonic food webs and interactions between physics (e.g. temperature), chemistry (e.g. nutrient) and biology (e.g. phytoplankton) in order to understand how different parts of the ecosystem affect one another... Read More →
