Remotely sensed mid-channel bar dynamics in downstream of the Three Gorges Dam, China [PDF]

open access: yes, 2020
The downstream reach of the Three Gorges Dam (TGD) along the Yangtze River (1560 km) hosts numerous mid-channel bars (MCBs). MCBs dynamics are crucial to the river’s hydrological processes and local ecological function.

Parks, people and pixels: evaluating landscape effects of an East African national park on its surroundings [PDF]

open access: yes, 2010
Landscapes surrounding protected areas, while still containing considerable biodiversity, have rapidly growing human populations and associated agricultural development in most of the developing world that tend to isolate them, potentially reducing their

A preliminary synthesis of major scientific results during the SALSA program [PDF]

open access: yes, 2000
The objective of this paper is to provide an overview of the primary results of the Semi-Arid Land-Surface-Atmosphere (SALSA) Program in the context of improvements to our overall understanding of hydrologic, ecologic, and atmospheric processes and their

Spatiotemporal Dynamics of Ecological Condition in Qinghai-Tibet Plateau Based on Remotely Sensed Ecological Index

open access: yesRemote Sensing, 2022
The eco-system in the Qinghai-Tibet Plateau (QTP) is extremely fragile, and highly vulnerable to climate change. Knowledge of the changes in the ecological conditions is vital to mitigate the impact of climate change. In this study, we investigated the trend of ecological conditions of the QTP using the remotely sensed ecological index (RSEI), which is

Ecological Quality Evaluation of Large-scale Farm Based on Improved Remote Sensing Ecological Index

open access: yes, 2023
Large-scale farms are pivotal sites for the development of the agricultural industry, and the quality of the ecological environment is a significant factor affecting the growth of cereal crops. Consequently, assessing the ecological quality of large-scale farms is of great importance.

Local forest structure variability increases resilience to wildfire in dry western U.S. coniferous forests. [PDF]

open access: yes, 2020
A 'resilient' forest endures disturbance and is likely to persist. Resilience to wildfire may arise from feedback between fire behaviour and forest structure in dry forest systems.

Vegetation Dynamics in Ecuador [PDF]

open access: yes, 2019
Global forest cover has suffered a dramatic reduction during recent decades, especially in tropical regions, which is mainly due to human activities caused by enhanced population pressures.
