Small Water Bodies with Big CO2 Effects

Credit: Via @ArcticLagoons on Twitter Arctic coastal watershed systems are some of the most threatened regions on Earth and have undergone substantial climatic, physical, and biological change with the warming of our Earth. Now, researchers at the Beaufort Lagoon Ecosystems LTER site have discovered that small coastal water bodies, especially ponds, are releasing carbon to… Read more »

To go or not to go (in the field)?

SCUBA diver examines kelp

Many ecologists are now faced with a choice: continue field measurements and manipulations or halt them voluntarily and accept the cost to their science and sometimes their budgets. the LTER Network Office offers some considerations for those faced with this difficult decision.

Can seagrass meadows mitigate climate change?

As anthropogenic carbon dioxide emissions continue to increase, scientists have now recognized seagrass meadows—which typically have high rates of carbon storage—as important ‘blue carbon’ sinks. However, rising ocean temperatures threaten seagrass meadows, along with their ability to retain carbon. This underlines the need for precise ecosystem data on the vulnerability and resilience of these meadows… Read more »

What makes a network work? Collaboration in the LTER Network

network analysis, based on site age, ecosystem type, number of shared publications and network centrality

A recent analysis of collaboration in the LTER Network reveals that LTER-related publications involve more collaborators, more institutions, persist for longer, and cover greater distances than other publications in the field of ecology. 

Thinking about long-term futures to make better decisions today

One approach to planning for sustainable cities is for researchers and practitioners to work together to develop scenarios that benefit communities as well as ecosystems. Central Arizona Phoenix LTER (CAP LTER) is taking an innovative approach… Read more »

LTER at Ocean Sciences Meeting 2020

In 2017, the LTER Network saw the addition of three new marine and coastal sites. The new sites—Northeast U.S. Shelf (NES), Northern Gulf of Alaska (NGA) and Beaufort Lagoon Ecosystems (BLE)—are all well-represented among the 41 talks and posters presented by LTER researchers at the 2020 AGU Ocean Sciences Meeting. Presentations from these and other… Read more »

2020 Synthesis Working Groups Announcement

The LTER Network Office announces new synthesis project awards: A global synthesis of multi-year drought effects on terrestrial ecosystems; A multi-biome synthesis investigating the controls on river Si exports; and Ecological Metagenome-derived Reference Genomes and Traits (EMERGENT).

Cold, Dry, and Phosphorus Limited: microbial activity in nutrient poor habitats

rocky, mountainous landscape

High elevation and high latitude ecosystems are particularly vulnerable to climate change impacts because they represent the upward range limits for organisms that are adapted to cold temperatures and low nutrient levels. Two of the biggest threats to high elevation communities are nutrient deposition (e.g. nitrogen) and climate warming. A new study by Bueno de… Read more »
