Sharks can help marine ecosystems survive effects of climate change, study finds
When a major hurricane, extreme heat or other climate threat devastates an ocean’s lifeblood, its recovery could be aided by the presence of sharks.
Secrets of past warming help protect future ecosystems
In a new study from the University of Copenhagen, an international team of scientists has identified past global warming events similar to those anticipated in the coming decades.
What do gardens bring to urban ecosystems?
"A healthy community requires healthy soil." This idea spurred a consortium of researchers, farmers, and community garden practitioners to dive into the challenges — and opportunities — of urban agriculture.
Antarctic ecosystems under threat from invasive flightless midge, scientists warn
An invasion of flightless, biteless midges have arrived uninvited in Antarctica where their rapid proliferation represents a major threat to the fragile ecosystem, scientists have warned.
How flowering plants became dominant in ecosystems across globe?
We may generally think that during the whole course of the long history of life, or at least much of it, nature has been ornamented by flowers. This notion, however, is wrong. In fact, flowering plants came very late to the arena of nature, some 290 million years after the first known land plants appeared on the surface of our planet. But how did flowers evolve and rapidly become dominant in ecosystems across the world? This persisting question and the “abominable mystery,” as Charles Darwin once put, seems to have been resolved at last, a new study suggests.
Effects of species extinction on complex ecosystems
Research by the University of Southampton has found that methods used to predict the effect of species extinction on ecosystems could be producing inaccurate results.
Ecosystems in southeastern US vulnerable to climate change
At least several southeastern US ecosystems are highly vulnerable to the impacts of present and future climate change, according to two new United States Geological Survey (USGS) reports on research conducted by scientists with Interior Department's Southeast Climate Science Center.
Use of experiences vital for restoring ecosystems
In a joint North European and North American study led by Swedish researcher Christer Nilsson, a warning is issued of underdocumented results of ecological restorations. The researchers show that continuous and systematic evaluations of cost-efficiency, planning, implementations and effects are necessary in order to make use of experiences in future projects. The results have been published in the journal Ecology and Society.
Ozone does not necessarily promote natural ecosystems' decline
Environmental scientists at the University of Virginia have found that surface ozone, an abundant chemical known to be toxic to many species of vegetation and to humans, does not necessarily inhibit the productivity of natural ecosystems.
Good news about restoring river ecosystems
It is a commonly held belief that most ecosystems take about a lifetime to recover after damage is introduced by humans. However, researchers at Ohio State University are finding that initial recovery can be dramatic if the right conditions are present. The discovery was made while monitoring how dam removal impacted local species.
