Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
We describe tree‐ring reconstructions of spring (May‐June) precipitation and spring‐summer (May‐August) streamflow for north‐western Turkey, both beginning in AD 1650. These are among the first such reconstructions for the region, and the streamflow reconstruction is among the first of its kind for Turkey and the entire Middle East. The reconstructions, which both emphasize high‐frequency variations, account for 34 and 53% of...
Rapid tree growth with respect to the last 400 years in response to climate warming, northeastern Tibetan PlateauNARA Subscribed
Although global warming over the past century has been confirmed, the response of different regions to it is still uncertain. We developed a tree‐ring width chronology based on tree‐ring samples from juniper trees from the Xiqing Mountains in the northeast Tibetan Plateau, the central headwater area of the Yellow River. Using this tree‐ring chronology, the minimum winter half‐year (October–April) temperature for the research a...
