LTER at Ocean Sciences Meeting 2020

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 »

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

hemlock branches

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.

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.

Loner Lizards Stress in Shared Shade

Sceloporus jarrovi (Yarrow's spiny lizard)

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.

The fate of milkweed in a changing prairie system

Grazers on the Konza Prairie.

There is a surprising connection between the loss of prairie habitat in the Great Plains and the fate of Monarch butterflies. They may not be iconic in the American West, but Monarchs are important pollinators and prey for other species – and their populations in the United States are in steep decline. This is due… Read more »

Environmental History of the McMurdo Dry Valleys (MCM)

Lake Bonney Camp, Antarctica. Steve Chignell, 2016.

As part of their current project, researchers at MCM LTER are writing a detailed study on the environmental history of the McMurdo Dry Valleys. The monograph will be available online and published as a book with an academic press. For more information visit the McMurdo Dry Valleys History website.

Art & Ecology (VCR)

Each year, art and science teachers are invited to Art and Ecology workshops that link Plein Aire landscape painting and observational drawing to salt marsh ecology and climate change impacts on coastal ecosystems. Nearly 30 teachers per year participate in these professional development opportunities, and over half return for a 2nd workshop. Workshops focus on… Read more »
