LTER presents two plenary talks, plus results from synthesis working groups.
Individual talks and posters are listed and cover topics as diverse as the ecology of segregation, connectivity in barrier island communities, and modeling complex landscapes using machine learning.
Students from the Central Arizona-Phoenix, Sevilleta, and Jornada LTER visit and present posters at the CAP LTER All Scientists Meeting.
Sunshine, sand, and surf greeted participants of the 2018 LTER All Scientists’ Meeting as they arrived at Asilomar Conference Grounds in Pacific Grove, California. For four days, Asilomar was abuzz with the excitement of nearly 600 people sharing new scientific ideas and discussions. The theme of the 2018 meeting, Next Generation Synthesis: Successes and Strategies,… Read more »
The LTER Network Communications Office developed this monthly webinar series to keep investigators across the community apprised of new developments from the LTER synthesis groups. Webinars are hosted by the LTER Network Communications Office and the National Center for Ecological Analysis and Synthesis (NCEAS). Each of the speakers will discuss the opportunity they perceived to… Read more »
A recent meta-analysis found that aridity and low soil nitrogen levels seem to limit — rather than stimulate — plants’ ability to increase production of fine roots under elevated carbon dioxide conditions.

Within the science and natural resource management fields, people often say what gets measured gets managed. But in a well studied ecosystem such as the Everglades, how do decades of scientific information get accurately translated into restoration plans? Through the use of synthesis science, researchers from the Florida Coastal Everglades LTER site compiled interdisciplinary data to evaluate… Read more »
If carbon is currency, wildfires are the brokers; that is, they distribute carbon between land and air. In the short-run, fire emits carbon dioxide into the atmosphere. Over time, it also strengthens subsequent carbon uptake through plant regrowth. This exchange is like a natural Ponzi scheme – the carbon offsets from yesterday’s fires take up today’s emissions….

This month’s Ecology Letters features the first global quantitative synthesis of under-ice lake ecology. In their analysis of 36 abiotic and biotic variables across 101 lakes, the authors issue a call to arms for more winter lake research—currently the focus of only 2% of freshwater publications. As the climate warms, they warn, temperate ecosystems are losing ice, and limnologists remain unsure what ecological processes are at stake. Though winter has long been understood as an inactive period, some data suggests that winter foodwebs and physical processes remain vigorous and that winter ecology can drive subsequent summer conditions.
In stratified lakes, a large portion of phytoplankton biomass is found—not at the surface, where sampling is easiest—but somewhere down the water column, in what is known as a subsurface chlorophyll maximum (SSCM). Researchers in Global Lake Ecological Observatory Network (GLEON) compared automated high-frequency chlorophyll fluorescence (ChlF) profiles with surface samples and discrete depth profiles. In 7 of the 11 lakes studied, automated sampling captured the presence of SSCM’s that would have been missed by conventional sampling.
