Habitat loss and extinction in the hotspots of biodiversity. Extinction in nature reserves: the effect of fragmentation and the importance of migration between reserve fragments (a. k. a. The value of the world"s ecosystem services and natural capital. Migration: species" response to climatic variations caused by changes in earth"s orbit. Future habitat loss and extinctions driven by land-use change in biodiversity hotspots under four scenarios of climate-change mitigation. What we know: the reality, risks, and response to climate change. Tropical deforestation and fragmentation in the amazon: satellite data from 1978 to 1988. Ecosystem service examples: regulation of gas, climate, disturbances, and water. We are in the 6th extinction period, which is caused by humans. We only know about 1. 4 million species since we have not explored much of the earth (there could actually be 107-108 species) Acceleration of global warming due to carbon-cycle feedbacks in a coupled climate model. Projecting the future of the u. s carbon sink.
