SummaryThe mass-extinction episode underway is largely centred on tropical forests, insofar as they contain at least half of all Earth's species and they are being depleted faster than any other biome. [...] Key Result While these "hotspot" areas comprise less than 3.5 percent of remaining primary forests, they harbour over 34 000 endemic plant species (27 percent of all plant species in tropical forests and 13 percent of all plant species worldwide). They also feature 700 000 endemic animal species and…Expand

Endemism, diversity, and the threat of tropical moist forest extinctions
Extinction rates have risen to perhaps 104 the background rate. Much of this increase is due to projected influences of habitat loss on regions of the world with tropical moist forest. ThisExpand
Ecological monitoring: its importance for the conservation of biological diversity in the Eastern Arc forests
The Eastern Arc forests of Tanzania have been classified as one of the 14 most threatened tropical forest hotspots worldwide because of their unusual concentrations of endemic species and theExpand

TLDR
By concentrating on these hot-spot areas where needs are greatest and where the pay-off from safeguard measures would be greatest, conservationists can engage in a more systematised response to the challenge of large scale impending extinctions. Expand
Conservation priorities for forest-floor invertebrates of the southeastern half of Madagascar: evidence from two land-snail clades
TLDR
A preliminary answer is provided by the landsnail genera Cyclophoridae Boucardicus and Charopidae n. Expand
Evaluating Global Biodiversity Hotspots – Very Rich and Even More Endangered
TLDR
The areas where can be found the highest concentrations of endemic species and that also face the highest loss of natural habitats are called biodiversity hotspots, and the most important hotspots are Madagascar and the Indian Ocean Islands and Sundaland. Expand
Biodiversity conservation in tropical forest landscapes of Oceania
TLDR
Future hope for biodiversity conservation in tropical forests of Oceania lies in the renewed application of some traditional management constraints, the appropriate delivery of international support (such as may be available through carbon markets), improved quarantine processes, and through some protection naturally offered by the remote scattering of the islands that comprise OCEania.

The biological importance of the Eastern Arc Mountains of Tanzania and Kenya
Abstract The Eastern Arc Mountains are renown in Africa for high concentrations of endemic species of animals and plants. Thirteen separate mountain blocks comprise the Eastern Arc, supporting aroundExpand
Threatened plants of New Caledonia: Is the system of protected areas adequate?
TLDR
It is concluded that the current network of protected areas needs to be considerably expanded, in terms of both geographical/floristic subregions within New Caledonia and vegetation type covered. Expand

Three main approaches have been taken in recent studies performed by international conservation organizations to define priority conservation areas in the Mediterranean Basin. Expand

Contribution of nontrees to species richness of a tropical rain forest
TLDR
The first complete samples of all plant species and individuals for any lowland tropical forest in the world are reported, finding that the wet forest sample is by far the most species-rich such sample yet recorded and would remain so even if all tree species were excluded from the data. Expand
A Contribution of Rain Forest Research to Evolutionary Theory
TLDR
Studies in the Dipterocarpaceae and their forests over the last 20 years, in which I have collaborated, are beginning to elucidate this subject, and Richards (1963) has reasoned that ecology cannot afford to ignore the tropics. Expand
DISTRIBUTION PATTERNS OF ECUADOREAN PLANT SPECIES
TLDR
Ecuadorean flora is divided into three natural regions: the coastal plain, the Andes cordillera, and the eastern lowlands, which includes an estimated 20,000 species of vascular plants. Expand
Tropical Deforestation and Climatic Change
TLDR
A number of tropical crops are more vulnerable to climate than is usually the case with temperate-zone crops; and in many parts of the humid tropics, a marginal shortfall in precipitation can cause a substantial shortfall in the outputs of several staple crops. Expand
Biogeography of mammals in SE Asia: estimates of rates of colonization, extinction and speciation
TLDR
It is suggested that insular mammalian faunas typically are not in equilibrium, brrause geological and climatic changes can occur as rapidly as colonization and speciation, and any model of island biogeography to be widely applicable to insular faunaas must include speciation as a major variable.

TLDR
Very high tree species richness seems to be a general property of mature lowland evergreen forests on fertile to moderately infertile soils on all three continents. Expand
The vanishing Brazilian Atlantic forest
Abstract The Brazilian Atlantic forest constitutes a unique biome characterised by a high species diversity and a high level of endemism. A long history of land clearing for crops, pastures, timberExpand
A method for siting parks and reserves with special reference to Columbia and Ecuador
Abstract Many tropical countries contain large numbers of species with small geographical ranges, here, for convenience, termed endemics. South America, for example, harbours 440 endemic land birdsExpand
Changes in Plant Community Diversity and Floristic Composition on Environmental and Geographical Gradients
TLDR
The predictability of the fioristic compositions and diversities of tropical forest plant communities eems strong, albeit circumstantial, evidence that these communities are at ecological and perhaps evolutionary equilibrium, despite indications that certain aspects of their diversity are generated and maintained stochastically.

An analysis of epiphyte diversity and distribution is largely focused on the Neotropics, with a few comparisons with the Paleotropics are instructive. Expand
