Catastrophic shift in species diversity and productivity of an ecosystem
Ecology and environmental management is largely predicated on the view that ecosystems respond to environmental changes in a smooth and straightforward way. However, in Ecology Letters, May, Schmitz reports on a long-term field experiment that may prompt a hard, critical look at this reigning view.... view more (2004-05-04)

Grazer diversity counteracts plant diversity effects on ecosystem functioning in seagrass beds
Several influential experiments have shown that high plant diversity enhances ecosystem productivity, animal diversity, and invasion resistance. Yet theory predicts that plant and herbivore diversity, which often co vary in nature, should have countervailing effects on ecosystem properties. In the... view more (2003-07-02)

Brown Scientists Say Biodiversity Is Crucial to Ecosystem Productivity
In the first experiment involving a natural environment, scientists at Brown University have shown that richer plant diversity significantly enhances an ecosystem's productivity.   view more (2008-04-25)

Increased atmospheric carbon dioxide promotes algal growth
It is usually thought that unlike terrestrial plants, submerged plants like algae will not show any response to an increase of atmospheric carbon dioxide. This view may be biased by a neglect of the effects of the plants themselves on the water chemistry. In the June issue of Ecology Letters,... view more (2004-05-13)

Scientists to hand "crisis-hit" European fisheries a lifeline
Scientists from the University of Newcastle upon Tyne are leading an international programme aimed at handing European fisheries a lifeline. The University has just signed a Euro 1.5m. contract with the European Union for the development of a fisheries management framework that includes... view more (2001-11-26)

All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon... view more (2003-05-22)

Too much water, fertilizer bad for plant diversity
Too much of multiple good things - water or nutrients, for example - may decrease the diversity of plant life in an ecosystem while increasing the productivity of a few species, a UC Irvine scientist has discovered.   view more (2007-03-27)

Diversity in the deep blue seas
Nature magazine has published an article by Xabier Irigoien, a researcher at AZTI, the Basque Fisheries and Marine Technological Research Centre. The article provides data on the diversity of marine life at the bottom of the sea - particularly amongst algae. Species diversity Most research carried... view more (2004-06-28)

The high price of fatigue
Chronic fatigue syndrome (CFS) costs the United States over $9 billion each year in lost productivity according to an article published today in the Open Access journal Cost Effectiveness and Resource Allocation. This estimate, which is similar to the financial losses caused by digestive system... view more (2004-06-18)

Scientists find grass yield, carbon storage not affected by creepy-crawlies in the soil
New results from experiments at a unique ecology facility show that plant communities are dramatically altered by changes to the type of animal species living among their roots, but that key ecosystem measurements such as overall agricultural yield or the amount of soil carbon stored are... view more (2002-10-18)

Smokers not only take more time off work but they are less productive
Smokers not only take more time off work, but they are also less productive when they are working, shows research in Tobacco Control. In 1990 the US Office of Technology Assessment estimated that smokers cost employers $47 billion dollars in premature death and disability. The study involved around... view more (2001-09-04)

Mean Population Size Increases with Diversity
A long-standing debate in ecology has been the effect of diversity on the temporal stability of biological systems. Ecological theory predicts that the stability of populations should decline as community diversity increases, in part, because population size is assumed to decline with community... view more (2003-01-28)

Productivity rises when companies are facing closure
In companies that are slated to be shut down, productivity increases during the phase-out period itself. When management is busy dealing with matters other than daily operations, employees shoulder a greater responsibility for their work­-and efficiency is enhanced.   view more (2008-05-12)

Heart disease most expensive disease in UK, costing more than £7 billion a year
Coronary heart disease is the most expensive disease in the UK, costing over £7 billion a year in lost productivity and its impact on health care, reveals research in Heart.   view more (2002-11-18)

Gray wolves feed the masses while hunters feed the few
Gray wolves (Canis lupus) and human hunters both provide resource subsidies to scavengers in Yellowstone National Park, USA, by provisioning them with the remains of their kills. Carrion from wolf versus hunter kills is much more dispersed in both time and space. In the November issue of Ecology... view more (2003-10-08)

Media invitation: How many species in Noah's Arc?
Scientists gather in Mallorca (Spain) to assess the role of biodiversity in ecosystem function. The remarkable increase, towards the end of 20th Century in the rate of species extinctions and the loss of biological diversities in the planet's ecosystems have generated considerable concern on the... view more (2004-05-11)

Integrating restoration and conservation within the ecosystem approach
The Society for Ecological Restoration International (SER) released its May 2008 Briefing Note on the "Opportunities for Integrating Ecological Restoration & Biological Conservation within the Ecosystem Approach" at the Convention on Biological Diversity's Ninth Conference of the... view more (2008-05-19)

Study measures impact on productivity from functional gastrointestinal disorders
Those who suffer from common functional gastrointestinal disorders face work productivity losses and impairments in daily activity that amount to the loss of at least one day of work in a 40-hour workweek.   view more (2007-10-15)

Biodiversity conservation may help reduce the impacts of natural disasters - UNU
As ministers meet at the Eighth Meeting of the Conference of the Parties to the Convention on Biological Diversity (CBD COP-8), the United Nations University (UNU) urges governments to incorporate the Millennium Ecosystem Assessment (MA) findings in national planning processes and poverty reduction... view more (2006-03-30)

At the root of nutrient limitation, ecosystems are not as different as they seem
Anyone who has thrown a backyard barbecue knows that hot dogs are inexplicably packaged in different numbers than buns - eight hot dogs per pack versus 10 hot dog buns. Put in ecological terms, this means that weenie roasts are "hot-dog limited" - the extra buns are worthless without hot... view more (2007-11-09)

Research says privately funded R&D brings real gains to UK industry but finds no gain from foreign R&D investment.
New research by University of Warwick researcher Dolores A'ħon confirms the importance of privately funded research and development (R&D) for improving productivity across UK manufacturing industries. But there is no gain from foreign R&D investment. The research will be presented at the Royal... view more (2003-04-04)

Ecological restoration as a tool for reversing ecosystem fragmentation
Ecosystem fragmentation, along with many other global trends, is causing the natural world to undergo profound changes at all spatial scales from the micro-habitat to the continental.   view more (2008-10-09)

Theory of oscillations may explain biological mysteries
New mathematical studies of the interactions between oscillating biological populations may shed light on some of the toughest questions in ecology, including the number and types of species in an ecosystem, according to an article in the December 2006 issue of BioScience.   view more (2006-12-04)

Yale study offers new paradigm on ecosystem ecology
Predators have considerably more influence than plants over how an ecosystem functions, according to a Yale study published today in Science.   view more (2008-02-15)

Wildlife variety is the spice of life, say scientists
Strictly embargoed for release 19:00 BST / 14:00 EST Wednesday 4 July 2001 Biodiversity is more than just a pretty face - it has an important role in the workings of the living world say results published in Nature today by scientists in the UK and France. They find that the specialisation of... view more (2001-07-02)
