There's a place for us: New research reveals humanity's roles in ecosystems

Sun, 17 Feb 2019 14:25:18 EST ~ In two back-to-back symposia a cross-disciplinary cohort of scientists will present the first comprehensive investigations of how humans interacted with plant and animal species in different cultures worldwide through time. Find out more...

Understanding carbon cycle feedbacks to predict climate change at large scale

Sun, 17 Feb 2019 11:58:27 EST ~ Researches have identified long-disappeared forests available for restoration across the world. They describe how such an effort, could absorb as much as 135 gigatons of atmospheric carbon. Find out more...

In the squirrel world, prime real estate is determined by previous owner, study reveals

Wed, 13 Feb 2019 13:21:57 EST ~ Researchers found that if a squirrel inherits territory from a male rather than a female, it will have about 1,300 more cones in its midden. This stored energy will keep the squirrel alive an extra 17 days. For females it means she will enough food to breed earlier, resulting in her offspring leaving the nest earlier. This shows how the behavior of a complete stranger can impact the genetic contribution of another. Find out more...

New clues to predict tipping points for marsh survival

Wed, 13 Feb 2019 12:44:17 EST ~ Sea-level rise, sediment starvation and other environmental woes pose increasing threats to coastal wetlands worldwide. But a new study could help stem the losses by giving scientists a broader understanding of which wetlands are most at risk and why. The study assessed wetland distribution and resilience in hundreds of US estuaries at five different spatial scales. Its findings will help guide future efforts to preserve or restore threatened wetlands. Find out more...

Ecosystem changes following loss of great white sharks

Wed, 13 Feb 2019 08:16:48 EST ~ A new study has documented unexpected consequences following the decline of great white sharks from an area off South Africa. The study found that the disappearance of great whites has led to the emergence of sevengill sharks, a top predator from a different habitat. A living fossil, sevengill sharks closely resemble relatives from the Jurassic period, unique for having seven gills instead of the typical five in most other sharks. Find out more...

Re-establishing oyster beds to maximize their ecological benefits

Mon, 11 Feb 2019 13:15:30 EST ~ Researchers have developed a mapping tool that identifies sites for re-establishing oyster reefs that maximize their ecological benefits -- such as water filtration. This Geographic Information Systems (GIS)-based tool could inform restoration of other vital, sensitive coastal habitats. Find out more...

On the land, one-quarter of vertebrates die because of humans

Mon, 11 Feb 2019 08:32:14 EST ~ Humans have a ''disproportionately huge effect'' on the other species of vertebrates that share Earth's surface with us, causing more than 25 percent of the deaths among an array of species all over the globe, according to a recently published study. Find out more...

Think big, at least when it comes to global conservation

Fri, 08 Feb 2019 09:43:17 EST ~ According to a group of international researchers, the potential for large countries to contribute to environmental protection is being overlooked. The researchers recently examined the leverage an individual country has when it comes to protecting ecosystem values. And they say it isn't--nor should it be -- a level playing field. Find out more...

DNA traces on wild flowers reveal insect visitors

Fri, 08 Feb 2019 08:21:53 EST ~ Researchers have discovered that insects leave tiny DNA traces on the flowers they visit. This newly developed eDNA method holds a vast potential for documenting unknown insect-plant interactions, keeping track of endangered pollinators, such as wild bees and butterflies, as well as in the management of unwanted pest species. Find out more...

New way to help increase conservation impact

Thu, 07 Feb 2019 11:13:03 EST ~ A study reveals huge variations in the similarity and breadth of animal roles in nature across different parts of the world. Find out more...
