Abstract: "Impacts of global climate change on terrestrial ecosystems are imperfectly constrained by ecosystem models and direct observations. Pervasive ecosystem transformations occurred in response to warming and associated climatic changes during the last glacial-to-interglacial transition, which was comparable in magnitude to warming projected for the next century under high-emission scenarios. We reviewed 594 published paleoecological records to examine compositional and structural changes in terrestrial vegetation since the last glacial period and to project the magnitudes of ecosystem transformations under alternative future emission scenarios. Our results indicate that terrestrial ecosystems are highly sensitive to temperature change and suggest that, without major reductions in greenhouse gas emissions to the atmosphere, terrestrial ecosystems worldwide are at risk of major transformation, with accompanying disruption of ecosystem services and impacts on biodiversity."

Abstract: "Researchers say it’s important to not be seduced by the idea of protecting areas simply because they’re big and politically easier to protect, but instead to prioritize areas because they’re special and/or have key species in them. The study also revealed a surprising trend: existing protected areas around the world are good at covering at least some of the range of most of the world’s birds, mammals and amphibians."

Abstract: "India’s 2018 national tiger estimation will use an Android-based mobile application to streamline collection of field data on tigers and prey, add photos and GPS coordinates, record poaching and human-wildlife conflict, and reduce error in data entry. The M-STrIPES app uploads field data automatically to a remote central server for rapid analysis or stores the data on the user’s mobile phone until internet access is available. The app has been tested successfully in a few tiger reserves, made more user friendly, and is now being rolled out on a national scale, but can it help resolve discrepancies in survey results?"
