Forests take years to rebound from drought
July 30, 2015 04:38 PM - University of Utah

In the virtual worlds of climate modeling, forests and other vegetation are assumed to bounce back quickly from extreme drought. But that assumption is far off the mark, according to a new study of drought impacts at forest sites worldwide. Living trees took an average of two to four years to recover and resume normal growth rates after droughts ended, researchers report today in the journal Science.

How Corn Became King
July 28, 2015 09:12 AM - Kelly April Tyrrell, University of Wisconsin-Madison

Ten thousand years ago, a golden grain got naked, brought people together and grew to become one of the top agricultural commodities on the planet.

Now, University of Wisconsin-Madison researchers have found that just a single letter change in the genetic script of corn's ancestor, teosinte, helped make it all possible.

Publishing in the journal Genetics this month, UW-Madison genetics Professor John Doebley and a team of researchers describe how, during the domestication of corn, a single nucleotide change in the teosinte glume architectural gene (tga1) stripped away the hard, inedible casing of this wild grass, ultimately exposing the edible golden kernel.

Study: Temperature influences bird diversity loss in Mexico

The University of Kansas

A wide-ranging study of gains and losses of populations of bird species across Mexico in the 20th century shows shifts in temperature due to global climate change are the primary environmental influence on the distributions of bird species. “Of all drivers examined … only temperature change had significant impacts on avifaunal turnover; neither precipitation change nor human impacts on landscapes had significant effects,” wrote the authors of the study, which appeared recently in the peer-reviewed journal Science Advances. Using analytical techniques from the field of biodiversity informatics, researchers compared current distributions with distributions in the middle 20th century for 115 bird species that are found only in Mexico. They then compared those bird community changes to patterns of change in climate and land use.

Are You Smarter Than a Reptile?


July 29th, 2015
Are you smarter than a reptile? In many respects, you certainly are. After all, no reptile is going to read this article. However, our clearly superior intellectual abilities for certain skills has seduced us towards a dismissive attitude towards the surprisingly deep and broad range of analytical gifts of our companion creatures.
