Bird habitat changing quickly as climate change proceeds
December 28, 2015 07:06 AM - University of Wisconsin-Madison
The climatic conditions needed by 285 species of land birds in the United States have moved rapidly between 1950 and 2011 as a result of climate change, according to a recent paper published in Global Change Biology.
Bison get Christmas gift from Governor of Montana
December 23, 2015 08:24 AM - NRDC
In a big step forward for wild bison and all Montanans, today Governor Steve Bullock agreed to expand year-round habitat for wild bison in Montana outside Yellowstone National Park. Historically, thousands of wild bison have been hazed or slaughtered as they migrated from Yellowstone into Montana in the spring. This decision represents a significant change in bison management.
Following is a statement from Matt Skoglund, Director of the Northern Rockies Office at the Natural Resources Defense Council:
“Giving wild bison from Yellowstone year-round habitat in Montana is a welcome holiday offering from Governor Bullock. While I’d certainly love to see the state go further, this decision is a big step forward for wild bison in Montana, and it will show that wild bison and people can successfully share the Montana landscape outside Yellowstone National Park. When you consider this from a science, economics, public opinion, or common sense perspective, it makes sense for Montana to give wild bison from Yellowstone year-round habitat in the state.”
Coastal Marshes More Resilient to Sea-Level Rise Than Previously Believed
December 21, 2015 07:21 AM - Duke University
Accelerating rates of sea-level rise linked to climate change pose a major threat to coastal marshes and the vital carbon capturing they perform. But a new Duke University study finds marshes may be more resilient than previously believed.
Are you smarter than a fruit fly?
December 5, 2015 08:13 AM - Northwestern University
Northwestern University neuroscientists now can read the mind of a fly. They have developed a clever new tool that lights up active conversations between neurons during a behavior or sensory experience, such as smelling a banana. Mapping the pattern of individual neural connections could provide insights into the computational processes that underlie the workings of the human brain.
In a study focused on three of the fruit fly’s sensory systems, the researchers used fluorescent molecules of different colors to tag neurons in the brain to see which connections were active during a sensory experience that happened hours earlier.
Should we say goodbye to cacti?
December 2, 2015 07:23 AM - Kevin Mathews, Care2
It’s hard not to think of a cactus as a resilient plant. Living in hot, drought-stricken climates, if it can survive there, surely it can make it through anything. Sadly, this assumption is not reality for the cactus. As an international team of researchers discovered, nearly one-third of all cactus species face a looming threat of extinction.
Earth's first ecosystems were more complex than previously thought
November 28, 2015 06:44 AM - Universtity of Bristol
Computer simulations have allowed scientists to work out how a puzzling 555-million-year-old organism with no known modern relatives fed, revealing that some of the first large, complex organisms on Earth formed ecosystems that were much more complex than previously thought.
The international team of researchers from Canada, the UK and the USA, including Dr Imran Rahman from the University of Bristol, studied fossils of an extinct organism called Tribrachidium, which lived in the oceans some 555 million years ago. Using a computer modelling approach called computational fluid dynamics, they were able to show that Tribrachidium fed by collecting particles suspended in water. This is called suspension feeding and it had not previously been documented in organisms from this period of time.
These 10 Endangered Species are Running Out of Room to Roam
November 25, 2015 06:27 AM - Alicia Graef, Care2
It’s never been easier for us to get where we want to go, but our growing transportation systems mixed with development are taking a serious toll on wildlife, from tiny amphibians to large mammals, and pushing some who are already in danger of disappearing even closer to the brink.
A new report from the Endangered Species Coalition, No Room to Roam: 10 American Species in Need of Connectivity and Corridor, focuses on imperiled species who need just what the title says: room to roam.
Tourists may bring more home than just souvenirs
November 23, 2015 07:17 AM - Amy McDermott, MONGABAY.COM
Invasive species are great hitchhikers. They float in the ballast of ships, lurk in luggage, stick to unwashed sports gear, and cling to the soles of hiking boots. Scientists focus on stopping them from spreading because, once a new species gets rooted, it is expensive to manage and nearly impossible to remove.
Shipping and industry are the major pathways for invasive species, but studies have also shown that tourists can spread them into protected wilderness.
Half the world's natural history specimens may have the wrong name
November 17, 2015 07:07 AM - University of Oxford
Even the most accomplished naturalist can find it difficult to tell one species of plant from another or accurately decide which genus a small insect belongs to. So when a new specimen arrives at a museum, finding the right name from existing records can sometimes prove difficult. In turn, that can lead to specimens being given the wrong name – which can prove problematic for biologists.
Climate change is impacting birds more than previously thought
November 16, 2015 01:30 PM - Oxford University Press via ScienceDaily
Scientists have long known that birds are feeling the heat due to climate change. However, a new study of a dozen affected species in the Western Cape suggests their decline is more complex than previously thought -- and in some cases more serious.
According to the study, published in Conservation Physiology, by scientists from the Percy Fitzpatrick Institute at the University of Cape Town and Nelson Mandela Metropolitan University, there could be several reasons why birds are being negatively affected by human-made climate change.
