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.

Synthesis group: metacommunity dynamics and community responses to disturbance

Plans We set out to answer the general question: How do metacommunity dynamics mediate community responses to disturbance across the ecosystems represented in the LTER network? Metacommunity theory provides a framework to predict when different types of community assembly processes should control the composition of the species pool both at local and regional scales. Thus,… Read more »

Connecting Communities: LTER at ESA 2019

Logo for ESA 2019 Annual Meeting

LTER presents two plenary talks, plus results from synthesis working groups.
Individual talks and posters are listed and cover topics as diverse as the ecology of segregation, connectivity in barrier island communities, and modeling complex landscapes using machine learning.

Plant communities likely to be “vastly different” in the future

Grassland plot experiments at Cedar Creek LTER in Minnesota.

Farmers have known for centuries that fertilizer and irrigation help boost crop growth. But how does long-term application of fertilizer and water affect the composition of surrounding plant communities? In a study based at the Cedar Creek LTER, early signs suggest that added water and nutrients support the survival of new species and encourage more… Read more »

When it Rains, it’s Gonna Pour

Fires and floods are becoming all too common for coastal Southern California residents — but are these ‘extreme’ events likely to become even more frequent? Answering this question requires a comprehensive understanding of precipitation patterns in the region and how they are likely to change in the coming decades. Most previous research on climate change… Read more »

Q&A with Lauren Alteio: First isolation of giant virus genomes in soil from a forest ecosystem

Soil sample collection from the Harvard Forest in Petersham, Massachusetts.

Researchers Frederik Schulz (US Department of Energy’s Joint Genome Institute) and Lauren Alteio (University of Massachusetts) have discovered sixteen new giant viruses in soil samples from a long-term research site at the Harvard Forest LTER, described in a Nature Communications paper published in November 2018. Giant viruses are larger than most single celled organisms, and tend… Read more »
