Suriname is a small country, but it still has large tracts of undisturbed forests and rich wildlife. The authors discuss Suriname's plans to extend its already excellent network of protected areas and proposals to amend the hunting regulations. They also consider the country's eight monkey species, whose status can be regarded as indicative of that of the rest of the country's wildlife.

When the Indian Ocean atoll of Aldabra was added to the World Heritage List in 1982 it concluded 20 years of conservation effort to gain international recognition of its scientific importance. Its native wildlife, which is still remarkably intact, is, however, under threat. Only 27 km away, on Assumption Island, introduced bird species have established and are breeding. The author made a survey in October 1986 and among his findings was the particularly alarming discovery of a large population of red-whiskered bulbuls Pycnonotus jocosus, a nest predator of small passerines. Urgent action is required to remove the introduced species from Assumption, not only to protect Aldabra, but also to pave the way for conservation efforts on Assumption itself.

When managing small populations of endangered species, in the wild and in captivity, the premature death of even one individual may give cause for concern. The authors carried out whole-body radiographs (X-rays) on dead specimens of endangered Mascarene fauna—three species of birds, three species of reptiles and one bat species. They found skeletal problems indicating traumatic injuries and nutritional abnormalities. The authors suggest that the technique has a role to play in the investigation of deaths in populations of endangered species, and may provide information that leads to improved management of the species in question.

A dam is being built in Valia-Kalda, one of the ten national parks in Greece, despite the fact that this is not permissible under Greek law. Apart from the destruction caused by this activity, the park suffers from illegal hunting and over-grazing by livestock. The author, who was a member of two expeditions to Valia-Kalda in 1985 and 1986, describes the park, highlighting the features of special interest, and urges the Greek Government to safeguard it.

Palawan is one of the last relatively undeveloped islands in the Philippines. It still has extensive forest cover, and is of considerable conservation importance. However, the remaining forests are disappearing fast in the face of rapid population growth and uncontrolled logging. The authors visited the island to carry out ecological fieldwork in 1984. Here they report on threats to the forests, and discuss the prospects for sustainable development on Palawan.

Tsetse eradication and control programmes are often carried out in order that cattle can be introduced into the cleared area. The resultant destruction to habitats and wildlife can be considerable, and the majority of Africa's human population does not benefit from increased beef production. The authors say that we need a different approach, one that would concentrate on controlling sleeping sickness in humans, and on conserving the indigenous vegetation and fauna. They illustrate their approach by describing what could be done in a part of northern Zambia where sleeping sickness is endemic.

The black snub-nosed monkey Rhinopithecus bieti is facing extinction. Although some work has been done on the other Chinese snub-nosed monkeys, R. roxellanae and R. brelichi, very little is known about R. bieti. The author describes the results of the first detailed ecological survey of this species.

Few people see the clouded leopard, and its elusiveness makes it a difficult subject for scientific study. In Sumatra, there has been no serious research on the species, and the authors present the scanty information on its distribution there and stress the urgent need for a survey to establish the whereabouts of viable populations.

There has never been a thorough survey of Taiwan's clouded leopard population, and some believe it may no longer survive there. The author conducted a preliminary survey in 1986 and discovered that the last reported sighting of the species was in 1983.
