By Haley Dunleavy It’s a beautiful August day in the Arctic. The sun, now finally rising and setting after months of circling the sky, warms my face; neon yellows, pinks, reds, and greens of fall foliage speckle across the tundra, and most importantly, the previously incessant mosquitos have died off. I’m standing on a single-planked… Read more »

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.
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 »
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.

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 »
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 »
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).
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 »
GCE LTER researchers simulated the effects of long term (press) and short term (pulse) salt water intrusions in tidal freshwater marshes. Press conditions were more disastrous for the ecosystem, altering the N cycle, while the landscape was able to recover from pulse conditions.
