  • Age isn’t just a number: New research shows song sparrows are affected by climate change differently depending on age

    New research at the University of California, Davis, and Point Blue Conservation Science shows that song sparrows experience climate change differently at various ages. Two studies show the importance of considering the various stages and ages of individuals in a species to best predict not only how climate change could affect a species as a…

  • Crowd-sourced maps may help when disasters hit

    A free online map of the world that is created by its users is helping developing nations become more resilient to disasters, the Open Source Convention in Portland, United States, heard last month (22-26 July).

  • Does size matter (for lemur smarts, that is)?

    Does size matter? When referring to primate brain size and its relation to social intelligence, scientists at Duke University do not think the answer is a simple yes or no. In the past, scientists have correlated large brain size to large group size. However, in a new study published in PLoS ONE, scientists at Duke…

  • Greenland Ice Sheet is melting from the top and bottom

    New study shows that heat flow from the mantle contributes to the Greenland ice melt The Greenland ice sheet is melting from below, caused by a high heat flow from the mantle into the lithosphere. This influence is very variable spatially and has its origin in an exceptionally thin lithosphere. Consequently, there is an increased…

  • England is losing its meadows and marshes, impacting Long-eared bats

    Experts are warning that Britain’s gray long-eared bats are facing extinction because of the loss of the UK’s marshlands. What’s more, this may be just one casualty of increasing habitat loss. Britain’s Bat Conservation Trust, in a new publication called Conserving Grey Long-Eared Bats in our Landscape, has warned that there may be as few…

  • River health revealed in bird eggs!

    Birds’ eggs show just how serious a problem river pollution remains in the UK’s former industrial heartlands, according to a new study. Scientists analysed the eggs of Eurasian Dippers living in 33 rivers in South Wales, comparing the eggs of birds living along urban waterways with those of their rural peers. The city-dwellers’ eggs contained…

  • Woodpecker Species Benefit from Emerald Ash Borer

    Many of us have heard of the Emerald ash borer (EAB) – a highly invasive beetle known for it’s destruction of ash trees. After being discovered in the United States in 2002, this pesky little beetle has killed tens of millions of ash trees in Michigan alone. In addition to the tens of millions of…

  • Old-growth trees store half rainforest carbon

    Large trees store up to half the above-ground biomass in tropical forests, reiterating their importance in buffering against climate change, finds a study published in Global Ecology and Biogeography. The research, which involved dozens of scientists from more than 40 institutions, is based on data from nearly 200,000 individual trees across 120 lowland rainforest sites…

  • The Controversy Surrounding Fracking

    The father of fracking, George Mitchell, passed away July 26, leaving many to think about the legacy he leaves behind. Though he didn’t exactly invent fracking, the Houston native revolutionized the process by introducing horizontal drilling in the 1990s. Even more than two decades later, Mitchell’s process of fracking is still a touchy subject. Though…

  • New York City Turns to Composting

    In 2011, the United States produced 250 million tons of municipal solid waste, 56% of which was compostable materials. In New York City alone, more than 10,000 tons of trash is collected every day and shipped to landfills where organic materials decompose. Methane, a greenhouse gas 25 times more powerful than carbon dioxide, is produced…
