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.

We are expanding our vision to look beyond natural ecosystems and towards improving functional landscapes so they are not just making food,

The original agreement pledged to respect the principles of ecosystem-based management, an approach that takes into account human needs as well as ecological concerns.

UK ecosystem services declining: Nature Newsmany UK ecosystem services, including fish catches and soil quality,
are declining or have already become degraded as a result of over exploitation, poor management and habitat change,
according to the first national assessment of the United kingdom's ecosystems, released today. Over the past 60 years, there have been declines in around 30%of ecosystem services the benefits that humanity receives from the natural environment.
Only 20%of services got better, says The UK National Ecosystem Assessment, despite environment-improving measures such as the clean air act in the 1950s.
Crop production and species diversity in woodlands were among the few services that improved. Wheat yields doubled between the 1960s and 2010
Continued population growth and climate change in the country will probably put more pressure on ecosystems in the future, further reducing benefits and services.
Aquatic ecosystems are among those most degraded, for example from pollution from fertilisers running off of agricultural land, says Bob Watson, chief scientist for the UK Department for Environment, Food and Rural affairs,
As drivers of change in ecosystem services, climate change and invasive species will become more and more important over the next 50 years,

Before 1990, the fire rotation the amount of time needed to burn an area equal to an entire landscape of interest was more than 120 years in most of the Yellowstone ecosystem.
fire rotation will fall below 20 years for all but the most southeasterly portions of the ecosystem.
We want to understand ecosystems and the people who are living in them, Sachs said, warning his colleagues not to count on their governments for funding or leadership.

Palaeoecologists can usually only infer the richness of an ancient forest ecosystem by piecing together fossils of plant fragments of varying ages.

Ecosystem productivity is rising at high latitudes, with a roughly 50%increase in the amount of carbon cycling through northern landscapes since the 1950s,
while confirming that ecosystem productivity has continued to rise in the north. The researchers used models to analyse the carbon cycle and atmospheric circulation,
But the current work suggests that the change in the seasonal CO2 signal is too big to be explained by ecosystem shifts that far north.
For some, a hardline devotion to preserving native ecosystems is giving way to a more postmodern idea of
People are increasingly moving away from the belief that a native ecosystem is always best.
That idea grates with many restoration ecologists, says Hobbs. Yet studies increasingly suggest that altered ecosystems need not be bad for biodiversity or ecosystem function.
