Biodiversity and resilience of coral reefs
With over 3000 fish species, Indo-Pacific coral reefs represent one of the most diverse ecosystems on the globe. It is easy to assume that the loss of one or two species from these systems would have little impact. However, in an article in the April issue of Ecology Letters, Bellwood and... view more (2003-04-08)

Model successfully predicts large river system fish diversity
While scientists have developed methods to predict aspects of fish diversity in specific river locations, a model to understand what factors may drive a comprehensive suite of fish biodiversity patterns in a large and complex system of rivers has been elusive.   view more (2008-05-09)

Healthy coral reefs of Madagascar resisting damage from climate change
Healthy coral reefs of Madagascar's northeast coast have so far resisted the damaging effects of warmer ocean temperatures attributed to global climate change, say scientists who recently studied the region.   view more (2006-06-23)

New study explores patterns in species diversity and genetic diversity
As scientists, conservationists, and policy-makers wrestle with how to balance development with maintaining biodiversity, it's important to understand what controls patterns of biodiversity and how the biodiversity of a system will respond to different environmental scenarios.   view more (2005-07-27)

Overfishing in inland waters reduces biodiversity and threatens health
Systematic overfishing of fresh waters occurs worldwide but is largely unrecognized because of weak reporting and because other pressures can obscure fishery declines, according to an article in the December 2005 issue of BioScience.   view more (2005-12-01)

Farmed fish with parasites: impact on wild fish stocks
'Fish farming is often proposed as a solution to diminishing stocks of wild fish. Sadly, many parasites are threatening the future of aquaculture' [by depleting fish stocks], write Jo Cable and Phil Harris, of Cardiff and Nottingham Universities, in the August issue of Biologist. A wide range of... view more (2003-08-01)

Biodiversity hotspots, centres of endemicity, and the conservation of coral reefs
Coral reefs are renowned for their spectacularly high biodiversity, yet there is widespread concern for their future in the face of threats from land-clearing, over-fishing and global warming. A new study published in Ecology Letters by Australian scientists - Terry Hughes, David Bellwood and Sean... view more (2002-10-30)

Conservation of freshwater fish biodiversity: a challenge for the countries of the South
Humans have regularly been introducing exotic species into natural environments in order to provide for their nutritional necessities or meet less indispensable purposes such as horticulture, fishing or hunting.   view more (2008-03-27)

Coral reef fish harbor an unexpectedly high biodiversity of parasites
IRD researchers showed that Epinephilus maculates, a fairly abundant species of grouper off New Caledonia, was parasitized by 12 species of microscopic monogenean worms.   view more (2007-09-06)

A Roundtable for the Media at PrepCom4: Surviving the Third Millennium:
SE Asia is becoming increasingly vulnerable to global change (e.g. global warming, land-use change, urbanisation and dwindling resources). Will advances in modern technology and governance come to the rescue? This is one of the themes to be discussed by seven experts from a partnership of major... view more (2002-05-24)

Fatty fish protects against cancer
If you want to avoid cancer of the kidneys, a new major study from Karolinska Institutet in Sweden shows that eating salmon or other kinds of fatty fish a few times a month would be one good way to go about it.   view more (2006-09-20)

Life's a beach
Scientists at Plymouth Marine Laboratory are developing new methods to rapidly assess the biodiversity of living organisms on beaches and other marine environments. They have already found many new creatures which have not been classified in previous studies.   view more (2004-08-25)

How to Grow a Bigger Brain
Hatchery-reared steelhead trout show increased growth of some parts of the brain when small stones are scattered on the bottom of their tank, according to a new study by researchers at UC Davis.   view more (2006-03-07)

Oil palm research in context: Identifying the need for biodiversity assessment
Oil palm (Elaeis guineensis) cultivation has expanded dramatically in recent decades and is frequently cited as a major threat to tropical biodiversity.   view more (2008-02-13)

Not batty conservation
Noah had it easy. To weather the storm of impending disaster that would wipe-out life on earth, he simply protected a male and female of each species on the ark. Protecting contemporary biodiversity from the deluge of human activities that threaten life on earth is more difficult and requires a... view more (2003-09-17)

Rainfall and river networks prove accurate predictors of fish biodiversity
Princeton researchers have invented a method for turning simple data about rainfall and river networks into accurate assessments of fish biodiversity, allowing better prediction of the effects of climate change and the ecological impact of man-made structures like dams.   view more (2008-05-08)

Stress relief for bullies
At last! An excuse for those of us who take our work-related stress out on our family. Dr. Øyvind Øverli of the University of Oslo has discovered that dominant rainbow trout reduce their stress levels by venting their frustration on socially subordinate animals. Presenting his results at the... view more (2004-03-24)

Fish oils may hold key to cutting deaths from heart disease
Heart patients are being asked to eat more fish as part of a University of Edinburgh study in a study to see if improved diet can reduce the risk of coronary attacks. The study will look at the way fish and fish oil supplements could help reduce inflammation of the arteries and break down the blood... view more (2003-03-27)

Commercial fishing causes dangerous fluctuations in fish populations
Commercial fishing causes serious fluctuations in fish populations leaving them in danger of total collapse, says new research published today.   view more (2006-10-19)

PROJECT EXAMINES NEW TECHNOLOGIES AND AGRICULTURE
Professor Joyce Tait of the Research Centre for Social Sciences at the University of Edinburgh is joint co-ordinator of the 44-month project, which arose from her earlier work with Scottish Natural Heritage entitled 'Targeted Inputs for a Better Rural Environment' (TIBRE). Says Professor Tait:... view more (1999-01-22)

Manipulating biotope space can enhance beneficial biodiversity effects
Using diverse plant mixtures instead of monocultures can increase yield and other ecosystem goods and services on which humans depend. Recent studies showed that such beneficial effects of biodiversity depend on complementarity between species in resource use, as is the case if species root in... view more (2004-06-10)

Groundbreaking research in Scotland
A £5.85 million pound study of the soil in the Cheviot Hills has finally come to an end, producing a huge wealth of new information for scientists.   view more (2004-03-31)

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)

Hotspots of mercury contamination identified in eastern North America
A US and Canadian research team surveying mercury contamination in fish and birds in the northeastern United States and southeastern Canada has identified five "hotspots" where concentrations of the element exceed those established for human or wildlife health.   view more (2007-01-03)

Salmon go veggie to save wild fish stocks
Salmon, like humans, require omega-3 fatty acids in their diet to function healthily. But as the fish farming industry expands, feeding salmon and other aquatic species with pellets containing fishmeal and oil derived from processing wild-caught marine fish is unsustainable in the long term.   view more (2006-04-04)
