Climate migration in the face of climate change
February 11, 2014 09:41 AM - Julie Cohen, University of California, Santa Barbara

As climate change unfolds over the next century, plants and animals will need to adapt or shift locations to follow their ideal climate. A new study provides an innovative global map of where species are likely to succeed or fail in keeping up with a changing climate. The findings appear in the science journal Nature.

Calculating your water footprint
February 10, 2014 11:01 AM - Robin Blackstone, ENN

Water scarcity affects 2.7 billion people worldwide for at least a month each year and in the same way that each of us has a carbon footprint, Professor Arjen Hoekstra of the University of Twente in the Netherlands posits that every person also has a "water footprint". Our water footprint is calculated by counting the amount of fresh water that we each use daily and the amount of water required to produce the goods and services that we consume. Due in large part to our monthly water bill, we recognize our daily fresh water use more than we do the amount of water that it takes to produce other foods and products that we consume. We more commonly think about water consumption in terms daily showers dishwasher and sprinkler usage or dripping spigots.

A Mexican "bee-rometer"
February 7, 2014 05:17 PM - Beth King, Smithsonian Tropical Research Institute

Mexico is the fourth largest honey producer and fifth largest honey exporter in the world. A Smithsonian researcher and colleagues helped rural farmers in Mexico to quantify the genetically modified organism (GMO) soybean pollen in honey samples rejected for sale in Germany. Their results will appear Feb. 7 in the online journal, Scientific Reports.

The first big bite!
February 7, 2014 11:43 AM - Gareth Trickey, University of Toronto

The first top predators to walk on land were not afraid to bite off more than they could chew, a University of Toronto, Mississauga study has found. Graduate student and lead author Kirstin Brink and U of T Biology Professor Robert Reisz suggest that Dimetrodon, a carnivore that walked on land between 298 million and 272 million years ago, was the first terrestrial vertebrate to develop serrated ziphodont teeth. According to the study published in Nature Communications, ziphodont teeth, with their serrated edges, produced a more-efficient bite and would have allowed Dimetrodon to eat prey much larger than itself. While most meat-eating dinosaurs possessed ziphodont teeth, fossil evidence suggests serrated teeth first evolved in Dimetrodon some 40 million years earlier than theropod dinosaurs.
