IUCN

The deep ocean is increasingly recognized as a major global reservoir of the Earth's biodiversity, although but a small fraction of the oceans' ecosystems found at depths below 200 meters have been studied.

The precautionary principle, or precautionary approach, is now widely accepted in environmental law and policy at international and, increasingly, national level.

Sharks and their relatives, the rays and chimaeras, are the diverse group of cartilaginous fishes that have evolved over 400 million years.

The system of protected area management categories lies at the centre of IUCN's work and its mission; their effective use is of fundamental concern to the Union and its members.

Poverty has become the central concern for development agencies, and because many of the areas that are most important for conserving biodiversity are occupied by poor people, or have poor people living around them, the relationship between poverty and protected areas can no longer be ignored.

Biosafety and genetically modified organisms (GMOs) are amongst the most complex of biodiversity issues: from species conservation, to sustainable livelihoods, to socio-cultural policy.

This review of the European bison’s (Bison bonasus) status clearly indicates that, through proper management and conservation, its present numbers and distribution have improved significantly since its extinction in the wild at the beginning of the 20th century.

There is increasing recognition of the value that local, indigenous and mobile communities can bring to the process of conserving biodiversity, and of the need for a range of conservation types from strict protection to multiple sustainable use.

The paper reports the insect and mite pests recorded and documented during 1948 and 2003 from the vegetable crops (brinjal, potato, sweet potato, aroids, yams, cabbage, cauliflower, knolkhol, radish, turnip, lady's finger, tomato, cucurbits, beans, kangkong, lettuce and amaranthus) ecosystems fro

African elephants are confronted with habitat loss and degradation and increasing levels of human-elephant conflict. Management authorities in sub-Saharan Africa are increasingly turning to translocation as a means to meet such challenges.
