which is burning toward those groves said Matt Brooks Yosemite Field Station leader for the U s. Geological Survey's Western Research Ecology Center.
Under natural conditions these forests have burned for millions of years with frequent fires said Jon Keeley a fire ecologist with the U s Geological Survey who is based in Sequoia

The new recommendations to delist come to the USFWS from the Yellowstone Ecosystem Subcommittee of the Interagency Grizzly bear Committee.
We can help protect our ecology and waterways and help people to have access to fresh food It's all connected.
Instead they are an important part of the ecosystem America has nursed successfully back from the brink.
Experts say this is just a foretaste of major fires to come across the United states as altered forest ecology due to hotter and dryer conditions result in larger more destructive and more intense fires.
and dead dry wood and debris piled up on the forest floor according to studies by fire ecologists such as Stephens. Fires today burn hotter and higher up into the big trees (so-called crown fires).

Those tortoises kept Madagascar's unique ecosystem in check by munching on low-lying foliage trampling vegetation and dispersing large seeds from native trees like the baobab.
With their demise the composition of Madagascar's ecosystems changed shrubs and vegetation clogged the forest floor
and they plan to transplant a few hundred of them to Madagascar to help fill the ecological gaps left by their extinct kin.
This project is not an ecological substitution with an analogous species like what's been done on other Indian ocean islands;
Wacky Madagascar Animals Ecological shoes to fill Using fossils from two species of extinct Madagascan giant tortoises Pedrono located a group of very similar giant tortoises living on the nearby Aldabra Atoll.
and genetically it's likely they'll fill the same roles in the Madagascan ecosystem Pedrono said.
and other ecological interactions before the tortoises can breed and disperse across the island. A'welcome breakthrough'The plan seems like a good one says Elizabeth Hunter an ecologist at the University of Georgia who has studied giant tortoise restoration on the Galapagos islands
but wasn't involved in Pedrono's research. I would fully support going forward with this plan Hunter said.

The study's leader Sassan Saatchi of NASA's Jet propulsion laboratory Pasadena Calif. said that more frequent droughts due to climate change could drag on rainforest ecosystems and the carbon cycle in the long run.
This may alter the structure and function of Amazonian rainforest ecosystems. The 2005 drought affected a much bigger area than scientists had estimated previously Saatchi's team found through satellite observations.

The findings are detailed today (March 19) in the Journal of Animal Ecology. Animal ecologists have been trying to figure out how seasonal conditions in the environment affect animal migration patterns
and how climate change can redistribute resources that affect those patterns. Keeping track of when polar bears move on

They would be appropriate for a general science class a biology class or an environmental science class.
While roads cover only a tiny fraction of the total land surface of South america's largest nation their effect on local ecosystems particularly rain forests may be huge.
The effects that roads have on local ecosystems extend far beyond the locations of the roads themselves.
and connected ecosystems can continue to thrive despite the intrusion of human infrastructure. But road construction is just one of many factors leading to the continued deforestation of the world's largest rain forest.
BIOMASS will be a hugely important instrument for global environmental science research in the coming years and its observations will be the basis of significant environmental policy in the areas of carbon cycling
#New US Natural Landmarks Relics of America's Past The National park service has designated two new national natural landmarks that stand as relics of ecosystems that were once widespread in the United states. The two new
That's when humanity's ecological footprint first exceeded the biocapacity of the planet. Before that people's ecological footprint measured as the area required to supply the food fish fiber

But the snakes have wreaked havoc on the ecosystem of Guam decimating the island's native bird population.
Conversely severe fires in ecosystems that have natural adaptations to intense burns should not be labeled catastrophes at least not in ecological terms.
Future fire regimes will present many new situations that will range only from bad to worse there is not a bright side to climate change in terms of conservation of native ecosystems.

Protecting rainforest ecosystems and protecting traditional rainforest cultures. Many in the first group overlooked the opportunity to enlist tribal inhabitants of the rainforest its natural guardians as allies.
The stability of the ecosystem tended to unravel during periods of major climate change and sociopolitical turnover the scientists found.
and his fellow researchers can't really tease apart the possible causes that led to these ecological changes.
The changes humans are inducing in the environment now are probably fundamentally different from the factors that drove ecological changes in the past Yeakel said.
We have to look at ecosystems as a continuum Yeakel said. We can't just look at the modern ecosystem.
We have to look at how it has functioned in the past and how has changed it over time to establish a baseline for how the system will change in future.
And in fact these fires are a bit like seeds in that they are a crucial part of the prairie ecosystem.
