The importance of being invertebrate

Article Abstract:

London Zoo, which may close in 1992, has an Invertebrate Conservation Centre where breeding programmes ensure the continuation of invertebrates, including the endangered Polynesian tree-snails, Partulas, but it may be impossibe to rehouse it. Some, such as the wart-biter, can resume life in the wild, some, such as red-kneed tarantulas, can be bred in captivity and some, such as the giant robber crab, exemplify biodiversity. They rely on suitable temperature, humidity, light and nutrition. This complicated care may not be available elsewhere.

Five goose steps to freedom; captive breeding has saved the rare Hawaiian nene

Article Abstract:

The Nene Intiative run by the WWT (Wildfowl and Wetlands Trust) is researching the reason as to why Hawaiian wild geese raised in capitivity do not adapt when put back in the wild. The WWT was founded in the 50s when only 30 nene were left. There were about 25,000 nene in the Haiwaiin islands during the 18th century. Reasons for low survival rates of hand-reared nenes are genetic disorders, disease, inadequate food supplies and predators.

Genetics: it's all in the mind

Article Abstract:

The theory of evolutionary psychology, which suggests that people's genes dictate how they behave, has attracted considerable controversy. Opponents of the theory regard this as genetic determinism, and argue that environment is also a significant factor in how people behave.
