Imminent collapse of the Caspian Sea stellate sturgeon (Acipenser stellatus): evidence from the Iranian fishery

Article Abstract:

Overexploitation and imminent collapse of the Caspian Sea stellate sturgeon (Acipenser stellatus) resource is discussed, as evidenced in the Iranian fishery, where average size of fish caught rate are declining. Only gillnets are allowed by law in the Iranian fishery, which is in the southern basin of the sea, which is surrounded by several countries, each with a sturgeon fishery.

The future role of Russian forests in the global carbon cycle

Article Abstract:

Russia's forest management policies should include provisions for regeneration. Although all forests in the nation are under state control, the future prospect of privatization may intensify development and harvesting, which would generate negative environmental impacts. These include a decreased capacity for Russian forests to participate in the global carbon cycle.

Decay resistance of Siberian larch wood

Article Abstract:

An analysis is presented on the hardiness of Larix sibirica Ledeb, or Siberian larch wood, specifically its natural resistance to decay. Also discussed are historical uses of the wood based on this trait, such as in ship-building for the Russian navy fleet of the 1700s and 1800s; decay resistance may be partly attributed to the density of the wood.
