Despite its great plant and animal diversity it is one of the least understood ecosystems for its microbial diversity.
This may have major implication on how nutrients are cycled in the new ecosystem. Any changes to the nitrogen cycle are likely to affect the carbon cycle
Also using our results we can start devising new methods to aid the recovery of disturbed ecosystems imagine a cocktail of microbes added for ecosystem restoration.
In the winter the penguins venture about 621 miles (1000 km) to the fringes of Antarctica to forage for food though exactly what they eat is said a mystery study co-author CÃ line Le Bohec a polar ecologist at the Centre Scientifique
But ecologists are concerned that such high frequencies can have damaging effects on plant and animal species that require longer fire-free intervals to complete their life cycles.
The ecological impacts of back burning are discussed rarely but may be quite substantial. Wildlife which can normally flee a fire front can become trapped between the bushfire and the back burn.
This can be avoided by having ecologists help design the footprint of a back burn but extreme bushfire situations may not allow sufficient time for fine-tuning.
if they present no threat to any valued economic or ecological assets. We are yet to achieve ecologically sustainable fire management of flammable landscapes.

The 210-million-year-old piece of wood contains the first fossilized fire scar ever discovered researchers reported here this week at the Ecological Society of America's annual meeting.

When it takes over ecosystems this invader causes soils to surrender their carbon and release it as greenhouse gas.
since overrun entire ecosystems destroying native long-needled pine forests woodlots and grasslands alike. In addition to the damage it inflicts by overwhelming other plants kudzu has indirect effects as well.
This means kudzu s impact is not only native ecosystems but agricultural productivity as well. Kudzu s direct and indirect cost to the US economy is estimated to be in excess of US$500M annually.
In a paper published in the journal New Phytologist plant ecologist Nishanth Tharayil and graduate student Mioko Tamura of Clemson University show that kudzu invasion results in an increase of carbon released from the soil organic matter into the atmosphere.
Instead the findings point to the fact that plant composition in different ecosystems could actually be managed to reinforce carbon retention in the soil
Millipedes return nutrients to the ecosystem and keep dead leaves from piling up in the forest.
Biodiversity offsetting should not just be about protecting ecosystems. The approach should also be fair to local communities not least
Blonder an ecologist at the University of Arizona in Tucson wanted to know why the deciduous angiosperms outcompeted their evergreen cousins during the cold dark years after the impact (called an impact winter.
The impact winter pushed ecosystems toward plants with faster growing strategies Blonder told Live Science in an email interview.

And then it has this third layer of ecology and nature reclaiming something over time that we as humans have torn apart in an instant.
and the well-being of the marine ecosystem Black explained. The winters we see robust growth in the trees we see poor growth in the marine ecosystem Black said.
Coastal upwelling happens during the winter when a strong high-pressure weather system develops along the west coast of the continent.
These organisms are the backbone of the marine ecosystem and support huge populations of fish and seabirds.
However ecologists and economists point out that the preventative methods of mitigating fire also equate to huge cost savings.
How prevention treatments help economically According to the Ecological Restoration Institute (ERI) at NAU forest treatments in Arizona typically thin 30 percent of an area at a cost of between $500 and $1000 per acre.

Regardless the FWS is again considering delisting the roughly 700 bears in the Greater Yellowstone Ecosystem contending they are supplementing their diet with more meat.
Nevertheless public concerns over health and ecology have led to GMO bans in some nations and a few localities in the United states most recently on the island of Hawaii.

#The Two Wildfires Everyone Should Be Talking About (Op-Ed) Wally Covington is the director of the Ecological Restoration Institute a Regents'professor of forest ecology at Northern Arizona University and one of the world
Covington has been studying the ecology of southwestern forests since the 1970s and his research has led to decades of improved evidence-based conservation techniques.
Based on the longstanding research at the Ecological Restoration Institute of Northern Arizona University these treatments included protecting the older trees mechanically thinning small young trees in select areas around the community to remove unnaturally high densities of trees
Forest restoration vital to ecosystems and to Arizona While the San juan and Slide fires provide good examples of successful treatments they are also clear indications that Arizona leaders cannot be complacent.

For tens of thousands of years buffalo fundamentally shaped Native american cultures and engineered the ecology of prairie ecosystems.
There is growing recognition that the absence of buffalo has led to deterioration of the ecological integrity of grasslands diminished the health of our people and led to an incalculable cultural loss.

Ecological restoration will require extensive native prairies that can support free-roaming buffalo that can fulfill their natural ecological role

I hope we can start watching urban ecosystems for problem insects and using that information to stand forewarned about future ecological changes in natural areas.

Biologist Sean Hoban uses mathematical and computational tools to develop guidelines for ecologists and others engaged in this work.
As a computational biologist I work in several fields of life science primarily in ecology and genetics and particularly with plants.
I especially like working in ecology as it involves studying the linkages between living things and their environment and because it requires big-picture thinking
and large-scale ecosystem processes such as decomposition and nutrient cycling. We are beginning to learn that the genetic diversity of keystone species such as common tree species is very important for the resistance of an ecosystem to disturbance as well as its ability to bounce back after disturbance.
There are still few examples of direct connections from genes to the ecosystem level but this is a whole new realm for both ecologists and geneticists.
