Consumer-mediated nutrient dynamics of marine ecosystems under the wake of global change Increases in the frequency and severity of disturbance events as a result of global change are altering population and community dynamics of marine animals. Given that animals are key recyclers of nutrients in many ecosystems, these ecological impacts may have consequences for ecosystem… Read more »
Reproduction is a key component of plant life cycles and is crucial for dispersal, however it has a surprisingly poorly understood relationship to environmental drivers. This is particularly true for plant species with highly variable reproduction over time, known as ‘mast seeding’. While mast-seeding patterns have been linked to weather (temperature, precipitation), describing past patterns… Read more »
All plants are somehow affected by global change, but their responses are inconsistent between ecosystems, a LTER Synthesis group finds.
Can plants dictate how soil microbes respond to nitrogen deposition? New research says no, and sheds light on plant-microbe dynamics.
At the Niwot Ridge LTER, community scientists expand the reach of pika research initiatives to understand how pikas might respond to climate change.
A new paper by Dr. Andrew Rypel uses long-term datasets to reveal spatial and temporal variation for fish in Wisconsin lakes.
Two new synthesis working groups, awarded in 2021, capitalize on the intensive and extended record of observation at LTER sites to shed light on thorny ecological questions.
Every year, the Eastern North Pacific population of blue whales migrates between their winter calving grounds off the coast of Mexico and their summer feeding grounds in the California coastal region. Scientists know that they time their migration to coincide with peak prey abundances, but the cues they use for this have been unknown—until now…. Read more »
In 2018, M. Jake Vander Zanden and Yvonne Vadeboncoeur were invited to give a plenary lecture at the International Society for Limnology (SIL) meeting in Nanjing, China. They spoke about their efforts to synthesize a more holistic understanding of the role of benthic productivity and food web pathways in lakes. The two began their journey… 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 »
