Legacy carbon takes a hit as younger forest stands burn

Aftermath of forest fire

In 2014, massive wildfires swept through the Northwest Territories of Canada, burning over two million hectares of boreal forest, as well as the highly organic soils on which they stood. Researchers with the Bonanza Creek LTER used this unplanned experiment to learn whether the carbon released from burned land had been recently deposited or if… Read more »

You don’t know what you’ve got ‘til it’s gone – or at least threatened

According to a new article in the journal Ecosphere, common species are often critically important as structural, dominant, or foundation species in… Read more »

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.

Integrating plant community and ecosystem responses to chronic global change drivers: Toward an explanation of patterns and improved global predictions

JRN LTER researchers prepare a precipitation addition/reduction experiment.

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 »

Understanding Farmer Attitudes Can Help Address Water Quality Issues

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 »

Can corals ride the tide of climate change?

Damselfish and their coral host (Pocillopora eydouxi).

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.
