Increasing demands on the world's natural resources pose a serious threat to palm biodiversity. This action plan identifies the most threatened palm species in order to present recommendations for conservation measures that cater to their specific requirements, and to provide strategic guidelines for the conservation and sustainable utilization of the many palms that provide food, construction material, and an important source of revenue for many people.

Download Palms in Forest Ecosystems of Amazonia Book in PDF, Epub and Kindle
Palms are tropical miracles. Heinrich Heine, the German poet, stated "Unter den Palmen wandert man nicht ungestraft", i.e., one does not wander unpunished under the palms. It was Professor H.C.D. de Wit who taught me this in the late 1950s, and it is a pleasure to forward this message to the next generation in such an appropriate book. Both authors, as I know them, will bear the punishment of the palms. They will never be without palm nostalgia if and when living somewhere outside this world's tropical and subtropical palm belt. Palm nostalgia goes further than palms alone. It concerns the landscape, the short but splendid sunsets and last, but not least, the tropical people. Their elegance of living, structured in subtler ways than managers will ever understand, their laughter which may be a more decisive weapon against the troubles besetting the tropics than mere economics, and their unique life force erupting on festive as well as sad occasions under the palms will always remain with those who w3)ldered beneath these trees. I know. I was there.

Download Biodiversity and Ecosystem Processes in Tropical Forests Book in PDF, Epub and Kindle
Although biologists have directed much attention to estimating the extent and causes of species losses, the consequences for ecosystem functioning have been little studied. This book examines the impact of biodiversity on ecosystem processes in tropical forests - one of the most species-rich and at the same time most endangered ecosystems on earth. It covers the relationships between biodiversity and primary production, secondary production, biogeochemical cycles, soil processes, plant life forms, responses to disturbance, and resistance to invasion. The analyses focus on the key ecological interfaces where the loss of keystone species is most likely to influence the rate and stability of ecosystem processes.

Southern Africa is certainly not a naturally bounded area so that there are several possibilities for delineating it and concepts about its extent. Wellington* discussed the various possibilities for delineation and suggested that one line stands out more clearly and definitely as a physical boundary than any other, namely the South Equatorial Divide, the watershed between the ZaIre, Cuanza and Rufiji Rivers on the one hand and the Z ambezi, Cunene and Rovuma Rivers on the other. This South Equatorial Divide is indeed a major line of separation for some organisms and is also applicable in a certain geographical sense, though it does not possess the slightest significance for many other groups of organisms, ecosystems or geographical and physical features of Africa. The placing of the northern boundary of southern Africa differs in fact strongly per scientific dis cipline and is also influenced by practical considerations regarding the possibilities of scientific work as subordinate to certain political realities and historically grown traditions. This is illustrated, for example, in such works as the Flora of Southern Africa, where the northern boundary of the area is conceived as the northern and eastern political boundaries of South West Africa, South Africa and Swaziland. Botswana, traditionally included in the area covered by the Flora Zambesiaca, thus forms a large wedge in 'Southern Africa'.

Download A Survey of the Lepidoptera, Biogeograhy and Ecology of New Caledonia Book in PDF, Epub and Kindle
I spent four months in New Caledonia in 1971 with the object of making a quantitative survey of the night-flying macrolepidoptera with light-traps and an assessment of the Rhopalocera and microlepidoptera. This fieldwork was financed by a Government Grant-in-Aid for Scientific Investigations adminis tered by the Royal Society, and by a grant from the Godman Fund. I devoted a further three weeks to sampling on Norfolk I. , and, with the help of local naturalists, Mr. and Mrs. F. JOWETT, was able to produce a detailed account of the biogeography and ecology of the moth fauna (HOLLOWAY, 1977). This book is an account of the results of the New Caledonian work, together with reviews of the geology, phytogeography and general zoogeography pre sented as background for the Lepidoptera fauna and its geography. Previous work on the macroheterocera, primarily papers by VIETTE (1948- 1971), had recorded not many more than a hundred species, a very low total considering the area of the island relative to that of the Fiji group where the moths were being studied by Dr. G. S. ROBINSON when the New Caledonian expedition was at the planning stage. The Fijian fauna then promised consider ably to exceed three hundred species. Evidently many more species awaited discovery in New Caledonia.
