Expanding the “bio” in biogeochemical modeling: including voles in arctic climate models
Explicit representation of voles improves models of the impacts of climate change on Arctic ecosystem function
It’s not the plants: nitrogen directly affects alpine soil microbes
Can plants dictate how soil microbes respond to nitrogen deposition? New research says no, and sheds light on plant-microbe dynamics.
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 »
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 »
Cold, Dry, and Phosphorus Limited: microbial activity in nutrient poor habitats
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 »
Sea level rise impacting nitrogen cycle in tidal freshwater marshes
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.
Diverse soil improves plant diversity after all!
It stands to reason that variable environmental conditions would support greater plant diversity, but few experiments have offered concrete support for the “environmental heterogeneity hypothesis.” In re-establishing tallgrass prairie, the correlation took over 15 years to emerge.
Can corals ride the tide of climate change?
Researchers at Mo’orea LTER did not observe evidence that corals acclimatize to ocean acidification, but they did observe that some are more sensitive to it than others.
Environmental History of the McMurdo Dry Valleys (MCM)
As part of their current project, researchers at MCM LTER are writing a detailed study on the environmental history of the McMurdo Dry Valleys. The monograph will be available online and published as a book with an academic press. For more information visit the McMurdo Dry Valleys History website.
