Protected areas in the Arctic Protected areas in the Arctic
The Arctic is a unique region in the world, with very little human activity and vast expanses of tundra and taiga that presents ecological values. This graphics presents the areas that currently are protected for conservation, as recognized by the IUCN in the World Protected Areas Database at UNEP-WCMC, 2005. Some areas, like the Dehcho territory in Canada have been placed under interim protection. The data for Russia has been updated from nation...

The economy of legal wildlife trade The economy of legal wildlife trade
The trade in wild species can contribute significantly to rural incomes, and the effect upon local economies can be substantial. The high value of wildlife products and derivatives can also provide positive economic incentives to provide an alternative to other land use options for the local people - to protect wild species and their habitats, and to maintain the resource for sustainable and profitable use in the medium and long term. Consequent...

Money talks for turtles - conservation and economy Money talks for turtles - conservation and economy
Marine turtles have been used for eggs, meat, shell, oil, leather or other products for 7000 years. Modern times have introduced another way for society to profit from these species - to generate economic income as a tourism attraction. Sound turtle management relies on local communities, which – as economic incentive - should receive a fair share of the revenues. In many cases, the bulk of the revenues from the local level end up elsewhere, eve...

Forest vs. Agriculture – the case of the Mabira forest reserve, Uganda Forest vs. Agriculture – the case of the Mabira forest reserve, Uganda
The Mabira forest reserve, on the shores of Lake Victoria hosts valuable wildlife, serves as a timber resource, provides ecosystem services for the water balance and the rainforests represents a tourist destination. Following a proposed plan for clearing a third of the reserve for agricultural use, the values of the forest were calculated by local researchers. This economic evaluation of the forest shows that from a short-term perspective, growin...

Major global bird migration routes to the Arctic Major global bird migration routes to the Arctic
Bird species that migrate to the Arctic coasts and wetlands arrive from nearly every corner of the planet. During the summer, the sun never or nearly never sets, resulting in a short but intensive breeding season when millions of migratory birds arrive in the Arctic to breed. The majority of these birds seek the wetlands and coastal shores of the tundra plains. No other place on Earth receives so many migratory species from nearly all corners of ...

Protected areas, Arctic and Antarctic Protected areas, Arctic and Antarctic
Protected areas are very important for conserving biodiversity. In these areas, human activities are managed to achieve specific conservation goals, for example, to protect a certain species or to conserve a representative habitat or ecosystem. The Arctic has many terrestrial protected areas, but is generally lacking in marine protected areas (MPAs). As the climate warms and the sea ice melts, there will be greater access for activities such as f...

Disappearing lakes - Old Crow Basin, Canada (1951-2001) Disappearing lakes - Old Crow Basin, Canada (1951-2001)
The Arctic contains a variety of types of lakes but overall, it is thermokarst lakes and ponds that are the most abundant and productive aquatic ecosystems in the Arctic. They are found extensively in the lowland regions of western and northern Alaska, Canada and Siberia. These (i.e., thaw) lakes are most commonly formed by the thaw of ice-rich permafrost, which leads to the collapse of ground levels and ponding of surface water in the depression...

Protected Areas in the Arctic Protected Areas in the Arctic
Protected areas have long been viewed as a key element for maintaining and conserving Arctic biodiversity and the functioning landscapes upon which species depend. Arctic protected areas have been established in strategically important and representative areas, helping to maintain crucial ecological features, e.g., caribou migration and calving areas, shorebird and waterfowl staging and nesting sites, seabird colonies, and critical components of ...

Trends in Arctic shorebird populations Trends in Arctic shorebird populations
Shorebirds are the most diverse group of Arctic breeding birds and one of the most abundant. From the Arctic, they migrate to their non-breeding grounds along well-defined flyways that circle the world. As a group, however, their recent conservation status has been unfavorable. Trend data are only available for 65 of the 112 breeding shorebird populations that are wholly or largely confined to the Arctic. Of these, 35 populations (54%) are in d...

Distribution and current trend of polar bear subpopulations throughout the circumpolar Arctic Distribution and current trend of polar bear subpopulations throughout the circumpolar Arctic
Polar bears occur in 19 relatively discrete subpopulations with an estimated worldwide abundance of 20,000– 25,000 animals. Our knowledge of the status and trend of each subpopulation varies due to availability, reliability, and age of data. Furthermore, for many subpopulations, there is limited or no data collected over a sufficient period of time to examine trends. Based on a 2009 review of the worldwide status of polar bears, one of 19 subpopu...

Trends in Arctic murre populations Trends in Arctic murre populations
The two species of murres (known as guillemots in Europe), the thick-billed murre, Uria lomvia, and common murre, Uria aalge, both have circumpolar distributions, breeding in Arctic, sub-Arctic, and temperate seas from California and northern Spain to northern Greenland, high Arctic Canada, Svalbard, and Novaya Zemlya. The thick-billed murre occurs mostly in Arctic waters, while the common murre, although overlapping extensively with the thick-bi...

Arctic sea ice food web - schematic illustration Arctic sea ice food web - schematic illustration
Sea ice represents a unique ecosystem in the Arctic, providing habitat to specialized iceassociated species that include microorganisms, fish, birds, and marine mammals. Individual species use sea ice in different ways depending on their biological needs. Ice algae form the base of the food web. Some algae stay attached to the bottom of the ice, some fall into the water column, and some fall to the bottom of the sea, and so provide food for speci...
