Nonlinear Changes in Dryland Vegetation Greenness over East Inner Mongolia, China, in Recent Years from Satellite Time Series

open access: yesSensors, 2020
Knowledge of the dynamics of dryland vegetation in recent years is essential for combating desertification. Here, we aimed to characterize nonlinear changes in dryland vegetation greenness over East Inner Mongolia, an ecotone of forest–grassland–cropland

The Observed Impacts of Wind Farms on Local Vegetation Growth in Northern China

open access: yesRemote Sensing, 2017
Wind farms (WFs) can affect the local climate, and local climate change may influence underlying vegetation. Some studies have shown that WFs affect certain aspects of the regional climate, such as temperature and rainfall.

Agricultural soybean and corn calendar based on moderate resolution satellite images for southern Brazil

open access: yesSemina: Ciências Agrárias, 2020
Knowledge of the agricultural calendar of crops is essential to better estimate and forecast the cultivation of large-scale crops. The aim of this study was to estimate sowing date (SD), date of maximum vegetative development (DMVD), and harvest date (HD)

Temporal trends in the enhanced vegetation index and spring weather predict seed production in Mediterranean oaks [PDF]

open access: yesPlant Ecology, 2015
The extremely year-to-year variable production of seeds (masting) is an extended plant reproductive behaviour important for forest dynamics and food webs. The dependence of these episodes of massive seed production on recently or long-term photosynthesised carbohydrates, however, remains controversial. In this paper, we explore whether vegetation (tree
