Ozark grasslands experience major increase in trees and shrubs

Thu, 21 Sep 2017 16:12:48 EDT ~ Woody vegetation, such as trees and shrubs, has increased dramatically in Ozark grasslands over the past 75 years, according to a study. If these ecosystems continue to favor woody vegetation, will it be possible to maintain open grasslands for the foreseeable future? Find out more...

Scientists and farmers work together to wipe out African lovegrass

Thu, 21 Sep 2017 10:17:41 EDT ~ New research and collaboration could lead to the eventual eradication of the highly invasive African lovegrass threatening pastures and native grasslands Australia-wide. What they discovered is that local knowledge is the key to a successful management approach. Find out more...

In times of climate change: What a lakes color can tell about its condition

Thu, 21 Sep 2017 09:50:24 EDT ~ With the help of satellite observations from 188 lakes worldwide, scientists have shown that the warming of large lakes amplifies their color. Lakes which are green due to their high phytoplankton content tend to become greener in warm years as phytoplankton content increases. Clear, blue lakes with little phytoplankton, on the other hand, tend to become even bluer in warm years caused by declines in phytoplankton. Thus, contrary to previous assumptions, the warming of lakes tends to amplify their richness or poverty of phytoplankton. Find out more...

Animal acoustic activity decline shows forest fire pollution wreaks havoc on wildlife

Wed, 20 Sep 2017 13:17:49 EDT ~ Forest fires in Southeast Asia during the El Nio droughts of 2015 caused considerable disruption to the biodiversity of the region due to the smoke-induced 'haze' they created, according to new research. Find out more...

10,000 year-old DNA proves when fish colonialized our lakes

Wed, 20 Sep 2017 10:45:44 EDT ~ DNA in lake sediment forms a natural archive displaying when various fish species colonized lakes after the glacial period. Scientists' analyses of the prevalence of whitefish DNA in sediment reveal that the whitefish came to Lake Stora Lgdasjn in Vsterbotten already 10,000 years ago, whereas Lake Hotagen in Jmtland had its whitefish only 2,200 years ago.

Fri, 15 Sep 2017 09:51:58 EDT ~ Popular portrayals of "nature reclaiming civilization" in flood-damaged New Orleans, Louisianna, neighborhoods romanticize an urban ecology shaped by policy-driven socioecological disparities in redevelopment investment, ecologists argue. Find out more...

Old fish few and far between under fishing pressure

Thu, 14 Sep 2017 15:23:43 EDT ~ A new study has found that, for dozens of fish populations around the globe, old fish are greatly depleted -- mainly because of fishing pressure. Old fish are increasingly missing in many populations around the world. Find out more...

Light at the end of the tunnel: Restored forest now shelters dozens of endangered species

Thu, 14 Sep 2017 15:22:46 EDT ~ A twenty-year effort to protect and manage tiny remnants of a dilapidated forest in Benin, along with its agricultural and fallow vegetation surroundings, resulted in 14 ha of rich secondary forest, which corresponds to the size of nearly 20 sacred groves. This sanctuary now protects the critically endangered red-bellied monkey together with 52 endangered plant species. Find out more...

'Keep it local' approach more effective than government schemes at protecting rainforest

Tue, 12 Sep 2017 09:31:16 EDT ~ Conservation initiatives led by local and indigenous groups can be just as effective as schemes led by government, according to new research.
