TL;DR: In this paper, the authors developed a new algorithm to segment individual trees from the small footprint discrete return airborne lidar point cloud and applied it to segment trees in a mixed conifer forest in the Sierra Nevada Mountains in California.

TL;DR: In this paper, the authors analyzed interannual variations of normalized difference vegetation index (NDVI) and their relationships with climatic variables (temperature and precipitation) and human activity in China between 1982 and 1999.

TL;DR: A comprehensive satellite-based evaluation of lake shrinkage across the Mongolian Plateau finds a greater decreasing rate of the number of lakes in Inner Mongolia than in Mongolia between the late 1980s and 2010, due mainly to an unsustainable mining boom and agricultural irrigation in the former.

TL;DR: This work describes a method for georeferencing locality descriptions that accounts for the idiosyncrasies, sources of uncertainty, and practical maintenance requirements encountered when working with natural history collections, and allows for the use of uncertainty in analyses that use these data.

TL;DR: In this article, the authors performed a satellite-based survey using multitemporal Landsat images from the 1970s to 2000s, combined with ground-based censuses to quantify the changes in all of the lakes on the plateau and the associated driving factors, and found that the number of lakes with a water surface area > 1 km2 decreased from 785 in the late 1980s to 577 in 2010.
