SummaryThis paper aims to throw light on the mass extinction that is overtaking Earth's species. [] Key Result The paper identifies another eight such areas, four of them in tropical forests and four in Mediterranean-type zones.
Biodiversity Hotspots in the Mediterranean Basin: Setting Global Conservation Priorities
Three main approaches have been taken in recent studies performed by international conservation organizations to define priority conservation areas in the Mediterranean Basin.
Evaluating Global Biodiversity Hotspots – Very Rich and Even More Endangered
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.
A new method to set conservation priorities in biodiversity hotspots
Abstract Prioritization of endemic, threatened species and the habitats where they live is a crucial point of conservation actions, particularly in areas with rich endemic floras. In this study, we
Biodiversity hotspots: A shortcut for a more complicated concept
Prioritization of sites for plant species restoration in the Chilean Biodiversity Hotspot: A spatial multi-criteria decision analysis approach
A Spatial Multi-Criteria Decision Analysis approach is used to help optimize the selection of sites for restoration initiatives of two endemic threatened flora species of the “Chilean Winter Rainfall-Valdivian Forest” Hotspot to provide an affordable methodology to bridge global-scale priority areas with local actionable restoration scales.
Endemism-based butterfly conservation: insights from a study in Southern Western Ghats, India
Background The Western Ghats, a biodiversity hotspot in India harbours a high percentage of endemic species due to its unique and diverse habitats. These species which cannot survive elsewhere due to
Quantity versus quality: Endemism and protected areas in the temperate forest of South America
Although the temperate forest of South America has more than 30% of its area under some type of protection, correlation between protected areas and the areas of endemism is remarkably low and less than 10% of protected areas are situated in areas that have the greatest value for conservation.
Impacts of Deforestation on the Conservation Status of Endemic Birds in the North Maluku Endemic Bird Area from 1990-2003
Satellite imagery has become a powerful tool to analyze land-use trends across large portions of the globe, including remote areas where access is logistically or political impossible. Due to the
Hotspots of biodiversity and conservation priorities: A methodological approach
It is demonstrated that hotspots are poor predictors of overall biodiversity and regional or rarity hotspots should generally be preferred to hotspots of species richness.
Biodiversity hotspots for conservation priorities
A ‘silver bullet’ strategy on the part of conservation planners, focusing on ‘biodiversity hotspots’ where exceptional concentrations of endemic species are undergoing exceptional loss of habitat, is proposed.


Threatened biotas: "Hot spots" in tropical forests

10 areas that, a) are characterised by exceptional concentrations of species with high levels of endemism and b) are experiencing unusually rapid rates of depletion are identified, so conservationists can engage in a more systematised response to the challenge of largescale extinctions impending in tropical forests.
Species richness and endemism in the Usambara mountain forests, Tanzania
This review presents brief accounts of the flora and of three invertebrate and four vertebrate groups and shows the percentage endemic taxa to vary from 2% to 95% as a proportion of the true forest species.
New Light on the Plant Geography of Ceylon. II. The Ecological Biogeography of the Lowland Endemic Tree Flora
The results are used to compare the characteristic of the west zone lowland forests of Ceylon with those in similar climates elsewhere, and in particular with the Mixed Dipterocarp forests of the Far East.
Some effects of colonization on the tropical flora of Amazonia: a case study from RondOnia
The situation in Rondonia has reached a critical state and it is crucial that every effort be made to obtain reserve areas to protect the unique fauna and flora of the Rond6nia region.
New light on the plant geography of Ceylon I. Historical plant geography
The historical plant geography of peninsular India and Ceylon is reviewed, and it is con- cluded from present evidence that the Deccan Plate has played an impor- tant part in the history of Dipterocarpaceae and Dilleniaceae and of suprageneric taxa notably of Palmae, Monimiaceae, Proteaceae, Myr- taceae, and Bombacaceae.

Preliminary floristic analysis of the major biomes in southern Africa
The biomes form two main groupings, those with winter rainfall and those with summer rainfall, and Succulent Karoo is most similar to Fynbos and Nama-Karoo ismost similar to Savanna.
