Crocodile tears and skins: international trade, economic constraints, and limits to the sustainable use of crocodilians

Article Abstract:

International trade in skins and meat of crocodilians is subject to economic constraints and there are limits to the sustainable use of crocodilians. Drastic population declines came from the trade in skins for exotic leather products and most of the animals have been designated as endangered species, although no species became extinct. Habitat loss has led to a crisis in some places, however, and a battle is going on between managed-harvest programs and trade restrictions. Protective pressure comes from the Convention on Intnl. Trade in Endangered Species of Flora and Fauna (CITES) (1975). Sustainability is the goal. The market for skins is cyclical and ways to diversify into local meat production or other industry would add value and increase sustainability. Ecotourism and other nonconsumptive uses must be considered.

A large-scale model of wolf distribution in Italy for conservation planning

Article Abstract:

The wolf once populated all of Europe, but by the end of the 19th century it was reduced to a few isolated populations on the Iberian peninsula, Italy, and the Balkans. In Italy the wolf population was reduced to about 100 in the 1970s, but increased to between 400 and 500 in the 1990s. Based on statistical models, the wolf population is expected to expand into the Alps.

Using Vascular Plants as a Surrogate Taxon to Maximize Fungal Species Richness in Reserve Design

Article Abstract:

Research on forest plots in Tuscany, Italy, show that vascular plants are not an effective tool to maximize species richness of fungi. Woody plant species yielded better results, but not in all combinations of sites.
