Book Description
"The genus Mitrephora (Annonaceae) comprises 47 species of small to medium-sized trees, growing in tropical lowland and submontane forests throughout Southeast Asia. The centers of diversity lie in Borneo, where there are 12 species, and the Philippines, where there are 11 species. The flowers are pendent and hermaphroditic, with two whorls of petals, of which the outer petals are larger. The inner petals are apically con-nivent over the productive structures, forming a partially enclosed pollination chamber with small apertures between the basal claws of the petals that enable entry by pollinators. A field study of the pollination ecology of M. heyneana in Sri Lanka (the first such study for the genus) revealed pollination by small nitidulid beetles, although it is possible that other species may be fly-pollinated. This monograph is the first comprehensive taxonomic revi-sion of the genus. The work is based on a comprehensive study of comparative morphology and anatomy, including a survey of previously published work. Conservation assessments are provided for each species, according to current IUCN Red List categories and criteria. All species are mapped and many are illustrated with line drawings and/or photographs. Separate keys for flowering and fruiting material are included, as well as regional keys. Seven new species (M. amdjahii, M. endertii, M. kostermansii, M. multifolia, M. sorsogonensis, M. sundaica, and M. uniflora) and one new combination (M. macrocarpa) are proposed"--Publisher's description.

Book Description
The Ecology of Papua provides a comprehensive review of current scientific knowledge on all aspects of the natural history of western (Indonesian) New Guinea. Designed for students of conservation, environmental workers, and academic researchers, it is a richly detailed text, dense with biogeographical data, historical reference, and fresh insight on this complicated and marvelous region. We hope it will serve to raise awareness of Papua on a global as well as local scale, and to catalyze effective conservation of its most precious natural assets. New Guinea is the largest and highest tropical island, and one of the last great wilderness areas remaining on Earth. Papua, the western half of New Guinea, is noteworthy for its equatorial glaciers, its vast forested floodplains, its imposing central mountain range, its Raja Ampat Archipelago, and its several hundred traditional forest-dwelling societies. One of the wildest places left in the world, Papua possesses extraordinary biological and cultural diversity. Today, Papua’s environment is under threat from growing outside pressures to exploit its expansive forests and to develop large plantations of oil palm and biofuels. It is important that Papua’s leadership balance economic development with good resource management, to ensure the long-term well-being of its culturally diverse populace.

Book Description
The island of New Guinea has a high diversity of species and a high level of endemism, containing more than 5 percent of earth’s biodiversity in just over one half of a percent of the land on earth. New Guinea supports the largest area of mature tropical moist forest in the Asia/Pacific region. Papua New Guinea consists of the eastern part of the island of New Guinea, plus the islands of the Bismarck Archipelago, Buka, and Bougainville. There are between fifteen thousand and twenty thousand species of vascular plants in Papua New Guinea, with at least two thousand species of trees. The most important challenge for Papua New Guinea is the protection of biological diversity against the pressures resulting from global climate change, inappropriate destructive conversion of natural communities, unsustainable exploitation of forests, national economic development, and societal demands, including a fair sharing of the nation’s wealth and law and order issues. There are very few resources available to natural resource managers, environmental scientists, nongovernment agencies, and various extractive industries, most importantly, the timber industry that will assist in the identification of major tree species within Papua New Guinea. It is hoped that the publication of these three volumes will enable those who are responsible for natural resource management to improve their knowledge of the trees in these forests so that they can fully appreciate the richness of these biologically diverse forests. The forests of Papua New Guinea need to be managed sensitively and sustainably based on advanced evidence-based knowledge. The Trees of Papua New Guinea publication provides a comprehensive treatment of 675 species of trees (vol. 1: 261 species, vol. 2: 249 species, vol. 3: 165 species) that will assist in the identification of the trees of Papua New Guinea.
