All About IDI

More than 95 percent of the Earth's animal species are invertebrates (animals without backbones). They can be found in all habitats of the planet, from polar regions to rainforests to the greatest depths of the oceans. The number of invertebrate species living today is estimated to be between 3 and 15 million. By comparison, there are only about 47 000 species of vertebrates. And while most invertebrates are smaller than the smallest of vertebrates, the ecological services invertebrates provide are virtually immeasurable, and without them the life as we know it would cease to exist. Yet despite the ubiquity and unparalleled role invertebrates play in functioning of our planet they receive little or no attention from both general public and conservation authorities. To help remedy this situation, CABS launched the Invertebrate Diversity Initiative (IDI) in 2002, a program designed to promote invertebrates in conservation practices, both as indicators of the ecosystem health and subject of conservation actions.

IDI's activities currently concentrate on four areas:

  1. Data mining: Projects in this category are designed to extract conservation-relevant information from already existing sources of data (museum collections, paper-based publications etc.), which are currently inaccessible for large-scale analyses or decision making.

  2. Awareness building: Activities in this category are designed to bring attention of both the general public and conservation authorities to the largely ignored invertebrate organisms.

  3. Invertebrate surveys: The goal of projects in this category is (1) to perform initial invertebrate surveys in areas where such surveys have never been done, and (2) to complete invertebrate surveys and produce comprehensive databases, identification tools, and checklists in areas where such an activity is possible due to an already existing history of research.

  4. Taxonomic capacity building: Projects in this category aim to reduce the taxonomic impediment, especially in the developing world and/or for invertebrate taxa with the most severe shortage of taxonomic expertise.


"The Smaller Majority"

A new photographic book by Piotr Naskrecki highlights the beauty and threats to the survival of the smaller, often underappreciated members of tropical ecosystems. "The Smaller Majority" includes chapters on katydids, preying mantids, ants, and many others, and features over 400 photos of these and other invertebrates and little known amphibians.

Hotspots Revisited Available Online. Hotspots Revisited details the state of the earth's biodiversity hotspots. The book identifies 34 regions that cover only 2.3 percent of the Earth's surface but are home to 75 percent of the planet's most threatened species.
