Credit: CAP-LTER. CC BY-SA 4.0 Anticipating the needs of cities in the future is a key aspect of urban sustainability. 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.
A 16-year time series of the cyanobacterium Synechococcus at Martha’s Vineyard Coastal Observatory at the Northeast U.S. Shelf LTER illustrates a regular seasonal pattern of Syn as well as daily dynamics.
Soil carbon — which constitutes nearly 80% of the terrestrial carbon stock — is getting a lot of attention at the 2019 Fall Meeting of the American Geophysical Union (AGU). Ecological process ranging from microbial metabolism to homeowner landscape decisions impact the size and stability of the soil carbon pool — which in turn affects… Read more »
Using models to flesh out alternative futures for the Everglades under different rainfall scenarios, researchers provide much-needed detail for water and environment managers.
In 2014, massive wildfires swept through the Northwest Territories of Canada, burning over two million hectares of boreal forest, as well as the highly organic soils on which they stood. Researchers with the Bonanza Creek LTER used this unplanned experiment to learn whether the carbon released from burned land had been recently deposited or if… Read more »
Credit: Jack Pearce via Flickr (CC BY-SA 2.0)Species that are abundant often go ignored by conservation planning until an acute threat to their populations emerge – and by then, sometimes it’s too late. According to a new article in the journal Ecosphere, common species are often critically important as structural, dominant, or foundation species in… Read more »
