Looking to the past to prevent future extinction      (via sciencedaily.com)     Original source 

Anthropologists created a computational model to predict the likelihood of animal extinctions based on the complex interaction of hunting and environmental change.

The behavior of ant queens is shaped by their social environment      (via sciencedaily.com)     Original source 

The queens in colonies of social insects, such as ants, bees, and wasps, are considered the veritable embodiment of specialization in the animal kingdom. The common perception is that the queen's only task is to lay eggs -- and that this attribute is an inherent trait, not influenced by external factors. In contrast, recent research has demonstrated that in certain ant colonies the social environment can play a crucial role in shaping the behavioral specialization of the queens.

Curbside collection improves organic waste composting, reduces methane emissions      (via sciencedaily.com)     Original source 

Most organic household waste ends up in landfills where it generates methane, a powerful greenhouse gas. Composting food and garden waste instead of sending it to landfills can significantly reduce methane emissions and help mitigate global warming. A new study explores the effects of curbside compost collection programs.

Researchers find energy development and tree encroachment impact Wyoming pronghorn      (via sciencedaily.com)     Original source 

While Wyoming is home to some of North America's most abundant populations of pronghorn that have largely been stable in recent years, a new analysis shows that many herds are experiencing long-term declines in fawn production.

In paleontology, correct names are keys to accurate study      (via sciencedaily.com)     Original source 

When the skeletal remains of a giant ground sloth were first unearthed in 1796, the discovery marked one of the earliest paleontological finds in American history.

New maps help decision-makers factor albedo into tree-planting decisions      (via sciencedaily.com)     Original source 

A new study provides a global analysis of where restoration of tree cover is most effective at cooling the global climate system, considering not just the cooling from carbon storage but also the warming from decreased albedo. The researchers provide a tool practitioners and land managers can use to determine just how much of a problem albedo is for any reforestation or afforestation project on the globe.

Climate change will see Australia's soil emit CO2 and add to global warming      (via sciencedaily.com)     Original source 

New research has shown the warming climate will turn Australia's soil into a net emitter of carbon dioxide (CO2), unless action is taken. Soil helps to keep the planet cool by absorbing carbon, however as the climate gets warmer its ability to retain carbon decreases -- and in some instances can start to release some carbon back into the air. A global research team has predicted the changes in the amount of carbon in Australia's soil between now and the year 2100.

Global study of coastal seas as carbon dioxide reservoirs      (via sciencedaily.com)     Original source 

Coastal seas form a complex transition zone between the two largest CO2 sinks in the global carbon cycle: land and ocean. Ocean researchers have now succeeded for the first time in investigating the role of the coastal ocean in a seamless model representation.

How many fish constitute a school?      (via sciencedaily.com)     Original source 

Physicists are also interested in fish -- above all when they are researching the formation of structures. A research team has examined the schooling behavior of zebra danio (Danio rerio, also known as 'zebrafish') using methods from the field of multi-particle physics. They explain that groups of just three fish already move in a similar way to large schools while, by contrast, two fish display completely different behavior.

A self-cleaning wall paint      (via sciencedaily.com)     Original source 

Beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while -- but over time, the color changes and needs to be renewed. Now, special titanium oxide nanoparticles have been developed that can be added to ordinary, commercially available wall paint to establish self-cleaning power: The nanoparticles are photocatalytically active, they can use sunlight not only to bind substances from the air, but also to decompose them afterwards.

Wild bird gestures 'after you'      (via sciencedaily.com)     Original source 

A small-bird species, the Japanese tit (Parus minor), uses wing movements as a gesture to convey the message 'after you,' according to new research. When a mating pair arrives at their nest box with food, they will wait outside on perches. One will then often flutter its wings toward the other, apparently indicating for the latter to enter first. The researchers say that this discovery challenges the previous belief that gestural communication is prominent only in humans and great apes, significantly advancing our understanding of visual communication in birds.
