Extinction risk from climate change
Estimates of extinction risks for sample regions that cover some 20% of the Earth's terrestrial surface show the importance of rapid implementation of technologies to decrease greenhouse gas emissions and strategies for carbon sequestration.
Aligning Conservation Priorities Across Taxa in Madagascar with High-Resolution Planning Tools
It is shown, in an analysis of wide taxonomic and geographic breadth and high spatial resolution, that multitaxonomic rather than single-taxon approaches are critical for identifying areas likely to promote the persistence of most species.
Climate change adaptation for conservation in Madagascar
Madagascar's imperilled biota are now experiencing the effects of a new threat—climate change ([Raxworthy et al . 2008]). With more than 90% endemism among plants, mammals, reptiles and…
INDEPENDENT GENE PHYLOGENIES AND MORPHOLOGY DEMONSTRATE A MALAGASY ORIGIN FOR A WIDE‐RANGING GROUP OF SWALLOWTAIL BUTTERFLIES

Dispersal‐vicariance analysis using cladograms derived from morphology and three independent genes indicated a Malagasy diversification of lime swallowtails in the middle Miocene, suggesting diversification processes on the island of Madagascar may have contributed to the origin of common butterflies that now occur throughout much of the Old World tropical and subtemperate regions.

A novel method for examining and synthesizing spatial parameters such as species richness, endemism and community similarity is developed and demonstrated, demonstrating the potential of these analyses for understanding the diversification history of Madagascar's biota.
Deforestation and apparent extinctions of endemic forest beetles in Madagascar

The authors sampled the endemic forest-dwelling Helictopleurini dung beetles across Madagascar during 2002–2006, suggesting that deforestation has already caused the extinction, or effective extinction, of a large number of insect species with small geographical ranges, typical for many endemic taxa in Madagascar.
Combining global climate and regional landscape models to improve prediction of invasion risk
It is widely acknowledged that species distributions result from a variety of biotic and abiotic factors operating at different spatial scales. Here, we aimed to (1) determine the extent to which…
Global synthesis of conservation studies reveals the importance of small habitat patches for biodiversity

A global synthesis of the relationship between the conservation value of habitat patches and their size and isolation, based on 31 systematic conservation planning studies across four continents found that small, isolated patches are inordinately important for biodiversity conservation.
True navigation in migrating gulls requires intact olfactory nerves
Air-borne olfactory information seems to be important for migrating gulls to navigate successfully in some circumstances, as well as intact birds and gulls with the ophthalmic branch of the trigeminal nerve sectioned oriented towards their population-specific migratory corridor.
Biodiversity conservation: Uncertainty in predictions of extinction risk/Effects of changes in climate and land use/Climate change and extinction risk (reply)
Thomas et al. reply — We reconsider our estimates of climate-related extinction in the light of three questions raised by Thuiller et al., Buckley and Roughgarden and Harte et al.. We are able to…
