(Who Blessed) The Rains Down at the CAP LTER
An experimental approach takes a ground-level look at the ecological winners and losers of desert soil communities under shifting precipitation regimes in the Central Arizona-Phoenix LTER.
Across fourteen LTERs, soil carbon is a “gatekeeper” on the nitrogen cycle
An LTER cross site synthesis effort reveals that soil carbon availability determines nitrogen mineralization and nitrification rates across a wide diversity of terrestrial ecosystems.
Similar invasive insects coexist through slight differences in environmental responses
Novel analyses of a 31-year dataset on invading ladybeetles shows that small differences in habitat preference across years allow for two similar invading species to coexist while native species decline.
Cosmic Questions with Tremendous Practical Value: Exploring the Potential for Co-Production of Knowledge with Hubbard Brook in the White Mountain National Forest
Considerable work happens behind the scenes as Sarah Garlick, Hubbard Brook’s Director of Science Engagement, brings together researchers and forest managers to identify shared research priorities in New Hampshire’s White Mountain National Forest.
Swamp Eels Wreak Havoc on Small Species at the Florida Coastal Everglades LTER
Since its introduction in 2009, the swamp eel has nearly eliminated several populations of small aquatic species in the Everglades watershed. The new invasive may be more disruptive to the Everglades than the park’s flagship invasive, the Burmese Python, and brings a new challenge to Everglades management and restoration.
Spare a thought for the roots
Nutrient addition increases aboveground plant growth more than it increases belowground plant growth, suggesting that the two are not linked.
Data Analysts at the LTER boost working group productivity
The LTER Network Office hired two data analysts, Angel Chen and Nick Lyon, in 2021 to tackle short but critical wrangling tasks during working groups’ in-person meetings. Here’s how they’ve helped groups during the past year.
Forest understory biodiversity and climate change
Pacific Northwest forests contain some of the largest reserves of forests on the planet, but many questions remain unanswered about how drought and heat stress from climate change will change forest dynamics and biodiversity. RETs on this project will track understory plant populations and quantify interactions among the many important and diverse plant species in these understory ecosystems.
Alpine stream chemistries are changing, but rock glaciers might not have as much influence as previously thought
While glacial thawing shapes ecosystem processes in the Green Lakes Valley, long-term data shows that it alone cannot explain the changing spatiotemporal patterns of stream chemistries.
Do fish graze the way for coral recovery?
Fish clear space for corals to grow in small scale experiments. But does fish grazing cause reefs to recover faster? A new study says no.
