*UA researchers are looking for, among other things, how fire changed the landscape of the Northern Great Plains as ancient hunters went after big game.*

Researchers from the School of Anthropology at the University of Arizona are investigating the complex relationship between climate change and modifications that humans have made to the landscape. And among the tools they are using in the pursuit of this knowledge are a bunch of old tires.

Led by Maria Nieves Zedeño from the UA Bureau of Applied Research in Anthropology, the Kutoyis Archaeological Project is a four-year collaboration focused on prehistoric bison hunting societies in the Northern Great Plains. The project is funded by the National Park Service and the National Science Foundation. (more…)

Exeter Scientists Grow Plants with Friendly Fungi

By Guest PostAugust 1, 2011Environmentclimate change, drought tolerance, friendly fungi, higher food prices, plant growth, strain of trichoderma

The lack of rainfall and higher-than-average temperatures in spring 2011 were predicted to hit harvests, leading to higher food prices.

Climate change may mean that these dry and hot conditions will become more common in the UK, so researchers are looking at ways to make plants more tolerant of dry spells. (more…)

Symbiogenics — a New Strategy for Reducing Climate Impacts on Plants

Seattle – Rice – which provides nearly half the daily calories for the world’s population – could become adapted to climate change and some catastrophic events by colonizing its seeds or plants with the spores of tiny naturally occurring fungi, just-published U.S. Geological Survey-led research shows.

One in 10 species could face extinction by the year 2100 if current climate change impacts continue.

This is the result of University of Exeter research, examining studies on the effects of recent climate change on plant and animal species and comparing this with predictions of future declines.

Published in leading journal Proceedings of the National Academy of Sciences, the study uses the well-established IUCN Red List for linking population declines to extinction risk. The research examines nearly 200 predictions of the future effects of climate change from studies conducted around the world, as well as 130 reports of changes which have already occurred. (more…)

Evaluation of Climate Policy Rocketing But in an Undeveloped and Unsystematic Way

*New research led by the University of East Anglia and the VU University Amsterdam shines new light on the little studied but politically vital practices of climate policy evaluation in Europe.*

Published in the international journal Policy Sciences, a meta-analysis by a team of researchers from across Europe offers the very first systematic cataloging of the emerging patterns of policy evaluation undertaken in different parts of the European Union.

In the last decade or so the politics surrounding the development of new policies has attracted unprecedented attention. Many new targets and policies have been adopted. But a lot less is known about what is being done to check that the resulting policies are actually delivering on their promises. (more…)

*High-mountain wildflower season reduced, affecting pollinators like bees, hummingbirds*

It’s summer wildflower season in the Rocky Mountains, a time when high-peaks meadows are dotted with riotous color.

But for how long?

Once, wildflower season in montane meadow ecosystems extended throughout the summer months. But now scientists have found a fall-off in wildflowers at mid-season. (more…)
