LTER Science Update provides short, accessible articles describing recent news and publications from across the Network. We hope you will be informed and inspired. Subscribers can sign up online and manage their own subscription settings, so feel free to share with interested colleagues. Have a recent paper or project that may be of interest? Please send us a few basic details using our news submission form and we’ll follow up.
LNO and other organizational updates will continue to appear in Network News on a quarterly basis or as needed.
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.
Background and plans Many global change drivers (GCDs) lead to chronic alterations in resource availability. As communities change through time in response to these GCDs, the magnitude and direction of ecosystem responses are also predicted to change in a non-linear fashion. We proposed to examine whether plant community dynamics are predictive of shifts in ecosystem… Read more »
The Gulf of Mexico dead zone is predicted to be a near record size in 2019. By the end of summer, the hypoxic region at the mouth of the Mississippi River is expected to occupy over 22,000 square kilometers—an area the size of Massachusetts. The culprit? Nitrogen-based fertilizers applied to crops across the Midwest that… Read more »
Inspired by several citizen science projects, a team from Bonanza Creek LTER studied how changes to season lengths in Interior Alaska affected native and non-native species.
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.

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 »
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 »
Researchers from Coweeta LTER are changing the way we monitor drought by showing that indicators of drought can be monitored at large spatial scales and in near real-time.
The Knights Who Say “Ni” would be delighted by a growing trend across many of the planet’s major biomes—tree and grass species are being taken over by shrubbery. Unfortunately, this phenomenon isn’t so favorable for native vegetation that struggles to compete with an invading shrub army (the term ecologists often use is ‘woody plant encroachment’)….

Multidisciplinary research is a positive shift toward understanding the complexity of human-natural systems. However, combining social science and ecological science methods does not necessarily equate to integration of ideas. Drawing from their urban ecology and environmental anthropology backgrounds, a group of LTER researchers propose using conceptual frameworks that go beyond characterizing social-ecological interactions as stepwise… Read more »
Human introverts aren’t the only ones who get stressed in shared social environments. Lizards like patchy and spread out shaded spaces where they can avoid interactions with other lizards.
