Supreme Court rules habitat is home sweet home for endangered species

Article Abstract:

The US Supreme Court in a judgment in 'Babitt V. Sweet Home Chapter of Communities for a Great Oregon' on June 29, 1995, upheld regulations under the Endangered Species Act which prohibit substantial destruction of habitat. The case was centered around a Depart of the Interior regulation defining prohibited 'harm' to endangered species which was challenged by the timber industry. The ruling has created a controversy leading to the issue being raised in Congress. There is an uncertainty over the possible outcome but for the time the species are safe.

Alien species and the extinction crisis of Hawaii's invertebrates

Article Abstract:

Many native invertebrate species of Hawaii have become extinct due to the spread of alien species such as goats, cattle, horses, sheep, deer, pigs, ants and wasps. Many snails, phytophagous insects and Drosophila flies have become extinct or are on the verge of extinction because the alien species have destroyed their habitat. Species used for biological control of pests have also threatened the existence of many native species of freshwater snails and bugs such as the koa bug.

Alien snake threatens Pacific islands

Article Abstract:

The brown treesnake has had a significant impact on the ecology of the island of Guam since it was accidentally introduced there in the 1950s. This snake has led to a significant decline in the island's native fauna, including many species of native forest birds. It also threatens other islands in the region if it is accidentally transported from Guam. Efforts to limit the impact of the brown treesnake are now focusing on snake-proof barriers.
