Numerical study on wind profiles change trend of upright reticulation barriers under different configuration models

Frontiers in Environmental Science, 2023
To explore how to lay the same specifications to maximize the protection benefits of mechanical sand barriers is an essential issue in the actual production process. We used the Reynolds-Averaged Navier-Stokes (RANS) method and the shear stress transport

Strategic adaptive management planning—Restoring a desert ecosystem by managing introduced species and native herbivores and reintroducing mammals

Conservation Science and Practice, 2020
Arid rangelands are degraded worldwide, suffering vegetation transformation, soil erosion, introductions, and extinctions. Wild deserts is restoring a desert ecosystem in Sturt National Park, New South Wales, Australia (35,000 ha), eradicating or ...

Vegetation coverage of desert ecosystems in the Qinghai-Tibet Plateau is underestimated

Ecological Indicators, 2022
Accurate fractional vegetation coverage (FVC) detection is beneficial for evaluating the dynamics and development potential of desert ecosystem. However, at present the performance of the related published products in the Qinghai-Tibet Plateau (QTP)’s ...

Interactions between carbon and nitrogen dynamics in estimating net primary productivity for potential vegetation in North America [PDF]

, 1992
We use the terrestrial ecosystem model (TEM), a process-based model, to investigate how interactions between carbon (C) and nitrogen (N) dynamics affect predictions of net primary productivity (NPP) for potential vegetation in North America. Data on pool

Environmental Control on Transpiration: A Case Study of a Desert Ecosystem in Northwest China

Water, 2020
Arid and semi-arid ecosystems represent a crucial but poorly understood component of the global water cycle. Taking a desert ecosystem as a case study, we measured sap flow in three dominant shrub species and concurrent environmental variables over two ...

Comparative metagenomic analysis reveals mechanisms for stress response in hypoliths from extreme hyperarid deserts [PDF]

, 2016
Understanding microbial adaptation to environmental stressors is crucial for interpreting broader ecological patterns. In the most extreme hot and cold deserts, cryptic niche communities are thought to play key roles in ecosystem processes and represent ...

Factors controlling and variations of CO2 fluxes during the growing season in Gurbantunggut Desert

Ecological Indicators, 2023
Although previous studies have illustrated the variation of CO2 fluxes in different terrestrial ecosystems, more needs to be reported on desert ecosystems.

Forgotten Biodiversity in Desert Ecosystems

Science, 2012
As the world's governments congregate for the United Nations Conference on Sustainable Development (Rio+20), we call on them to address one of the greatest oversights in conservation in recent years: the neglect of desert ecosystems.

Local ecosystem feedbacks and critical transitions in the climate [PDF]

, 2009
Global and regional climate models, such as those used in IPCC assessments, are the best tools available for climate predictions. Such models typically account for large-scale land-atmosphere feedbacks.

Impacts of Land-Use Change on Ecosystem Service Value of Mountain–Oasis–Desert Ecosystem: A Case Study of Kaidu–Kongque River Basin, Northwest China

Sustainability, 2020
In this study, we used long time series Landsat data and ecosystem services coefficients for global and Chinese ecosystems during 1978–2018 to estimate the influences of land-use change on ecosystem services (ES) in Kaidu–Kongque River Basin (KKRB ...
