How the comb-jelly (Mnemiopsis leidyi) is spreading through European seas (invasive species) How the comb-jelly (Mnemiopsis leidyi) is spreading through European seas (invasive species)
The most threatening event for the Caspian ecosystem was the arrival of the North American comb jelly (Mnemiopsis leidyi). It was brought accidentally to the Caspian in the ballast water of oil tankers. Invasive and alien species can exploit ecological niches that are not currently occupied, and spread rapidly, out-competing indigenous species.

Overview of legal international caviar trade, 1998-2003 Overview of legal international caviar trade, 1998-2003
Four years ago Azerbaijan, Kazakhstan and Russia agreed to restrict further export of commercial fish products. All three countries, as well as Iran, are party to the UN Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

Total trade in sturgeon caviar, 1999-2003 Total trade in sturgeon caviar, 1999-2003
The caviar trade reportedly fell by about 70% between 1999 and 2003 but there is still every reason to monitor development of the sturgeon population and keep it on the list of endangered species. However it is not clear to what extent the temporary ban on caviar exports has boosted well established illegal domestic and international trafficking, obviously not accounted for in the official figures.

Human impact - West Asia Human impact - West Asia
Vast areas of the West Asia region are sparsely populated, and are showing low fragmentation, but these are the unproductive desert areas, which naturally have quite low biodiversity (although there might be rare species there).

Human impact - Southeast Asia and Australia Human impact - Southeast Asia and Australia
The region, with Australia, New Guinea and Indonesia have unique flora and fauna with high biodiversity and many areas that has seen little human impact. Population pressures, especially in Indonesia, are starting to threaten these unique habitats, with species such as Orangutan.

Fish catch and production Fish catch and production
Fishing activities have various negative impacts on marine ecosystems. The greatest cause for concern is the rapid depletion of fish population due to extensive commercial fishing. In 2002 72% of the world’s marine fish stocks were being harvested faster than they can reproduce. Bycatch – the harvest of fish or shellfish other than the species for which the fishing gear was set – accounts for a quarter of the total catch (27m tonnes in 2003) an...

Protected areas and conservation hotspots in Albania Protected areas and conservation hotspots in Albania
The graphic shows the protected areas of Albania, the proposed areas for protection and areas with endangered species. Albania is well known for its high diversity of ecosystems and habitats. Within its territory there are maritime ecosystems, coastal zones, lakes, rivers, evergreen and broadleaf bushes, broadleaf forests, pine forests, alpine and sub-alpine pastures and meadows, and high mountain ecosystems. It is rich in forest and pasture reso...

Re-infestation by 'Aedes aegypti' Re-infestation by 'Aedes aegypti'
Climate change affect the health of the population, not only through heat waves and waterborne diseases, but also as a result of the expansion of geographical areas conducive to the transmission of vector-borne diseases such as yellow fever, dengue and malaria. Species of mosquitoes, such as the group ‘Anopheles gambiae’, ‘A. funestus’, ‘A. darlingi’, ‘Culex quinquefasciatus’ and ‘Aedes aegypti’, are responsible for propagation of the majority of...

Barents Sea ecoregion conservation priority areas and oil and gas infrastructure Barents Sea ecoregion conservation priority areas and oil and gas infrastructure
The Barents Sea ecoregion - the part of the World Ocean north of the Nordic countries and Northwest Russia, has a unique environment with major sea bird colonies, rich benthic and plankton fauna and many major sea mammal species. To identify priority areas for conservation, thirty experts delineated sea areas based on ecological criteria in a WWF study. One of the main threats to the region is the development associated with the expansion of foss...

The Barents Sea ecoregion - the part of the World Ocean north of the Nordic countries and Northwest Russia, has a unique environment with major sea bird colonies, rich benthic and plankton fauna and many major sea mammal species. Within this ecoregion, this graphic illustrates the existing coverage of protected areas. One of the main threats to the region is the development associated with the expansion of fossil fuel extraction activities. Russi...

Species extinction rates Species extinction rates
Comparisons with the rate at which species have disappeared from the planet over a long period of Earth’s history indicate that humans have already increased extinctions levels dramatically. Projections suggest that this rate will take another big leap due to changes over the next 50 years. The bars represent the range of estimates in each case.
