The counter-intuitive conclusions appear in a new paper in the journal Ecology. Long vilified invasive species can sometimes become an ecosystem asset.
New Brown University research published online in the journal Ecology reports exactly such a situation in the distressed salt marshes of Cape cod.
There the invasive green crab Carcinus maenas is helping to restore the marsh by driving away the Sesarma reticulatum crabs that have been depleting the marsh grasses.
Humans have had far-reaching impacts on ecosystems said author Tyler Coverdale a researcher in the lab of lead author Mark Bertness chair of the Department of Ecology and Evolutionary Biology.
In this case an invasive species is potentially restoring a lost ecological function. Bertness and his group have been working on the marshes for years to trace the extent
which model what ecologists have begun recently to account for as non-consumptive effects. Lay people already call that effect scaring things away.
The ecological effect can be much greater much quicker. In two ways therefore the new study provides evidence for two newer views in ecology Bertness said.
One is that invasive species can sometimes turn out to be helpful. The other is that ecologists should account for the power of a predator's threat not just its actual attacks.
As for the marshes however Bertness said they need more help than the green crab alone can deliver.

African lions and villagers would benefit from fences to protect them from each other according to a new study by University of Minnesota researcher Craig Packer published online by Ecology Letters on March 5.

Because the findings from the Ecology Letters paper present such an enormous challenge for African governments and conservationists the best hope may be to advocate for a Marshall Plan for African wildlife conservation Packer said.

The synthesis distilled important findings from recent studies about how to make systems more resilient to stressors such as changes in climate introduced species and risk of uncharacteristically large and severe wildfires.
The authors considered the connections between the terrestrial forests and the streams as well as how restoration of ecological processes interfaces with the social and economic concerns of communities.
The synthesis integrates scientific findings from diverse disciplines using a conceptual framework of how social and ecological systems function in the Sierra nevada

Malmstrom said that plant virus ecology and the study of viral interactions between wild-growing plants and agricultural crops is an expanding field.
In the last 15 years disease ecology has really come to the fore as a basic science. Most of what is known about plant viruses comes from studies of crops.
To understand the complete ecology of viruses researchers are now studying these tiny organisms in nature too.
The mysteries of how plant viruses can play a role in ecosystem properties and processes in natural ecosystems are emerging more slowly Malmstrom said.
Malmstrom said it's important to catch up in our understanding of viral ecology as there are any number of societal issues that need to be addressed in this area.

and Mexico according to a University of Michigan ecologist who studies the disease. The current outbreak of coffee rust is seen the worst in Central america
U-M ecologist John Vandermeer has operated research plots at an organic coffee plantation in southern Chiapas Mexico for about 15 years.
They all say that it's the worst explosion of this disease they've ever seen said Vandermeer a professor in the Department of Ecology and Evolutionary Biology and at SNRE.
The move to sun coffee results in a gradual breakdown of the complex ecological web found on shade plantations.
What we feel has been happening is that gradually the integrity of this once-complicated ecosystem has been slowly breaking down
And this year it seems to have hit a tipping point where the various things that are antagonistic to the roya in a complex ecosystem have declined to the point where the disease can escape from them
The researchers'results reported this month in the American Chemical Society journal Environmental science and Technology are the latest in a long effort to understand the environmental aspects of antibiotic resistance which threatens decades of progress in fighting disease.
#Tree die off triggered by hotter temperaturesa team of scientists led by researchers at Carnegie's Department of Global Ecology has determined that the recent widespread die off of Colorado trembling aspen trees is a direct result of decreased precipitation

Forests store about 45 percent of the carbon found on land remarked William. Widespread tree death can radically transform ecosystems affecting biodiversity posing fire risks
Rapid shifts in ecosystems particularly through vegetation die offs could be among the most striking impacts of increased drought
