The lipster

Article Abstract:

The discovery of a tiny and strange invertebrate, Symbion pandora, catches world attention because of its unique lifecycle. It lives on lobster's mouth parts, sticking through an adhesive disk. The animal reproduces asexually, but also exhibits a bizarre sexual stage. Some develop a dwarf male with only reproductive organs and brain. Others have dwarf females in their body. Peter Funch and Reinhardt Kristensen feel that it deserves a phylum of its own, as it is difficult to fit it into the existing scheme of things.

The diet doctor: wildlife nutritionist Ellen Dierenfeld decides what's for dinner for more than 8,000 animals

Article Abstract:

Ellen Dierenfeld's responsibilities as nutrition dept head for the Wildlife Conservation Society go beyond feeding 8,000 animals to doing original research. As zoo animals live longer, she must puzzle out the dietary components of age-related ailments. She refines the diets that zoos have developed based on domesticated kindred to their animals, and wants to standardize diets at all five of the Society's wildlife centers. Her work may lead to recommendations about the size and content of animal sanctuaries.

War and wildlife in Georgia

Article Abstract:

Georgia, which is rich in flora and fauna, faces the problem of poaching and trophy hunting like other newly-independent republics of the former Soviet Union. Noah's Ark Center for the Recovery of Endangered Species is fighting both on ecological and political fronts. The weapons from the 1990 civil war are used for hunting the animals in wildlife sanctuaries. Poaching reduces the number of snow leopards, tigers, and wild sheep in the central Asian republics of Kazakhstan and Turkmenistan.
