Potential distribution of three types of ephemeral plants under climate changes

open access: yesFrontiers in Plant Science, 2022
BackgroundArid and semi-arid regions account for about 40% of the world’s land surface area, and are the most sensitive areas to climate change, leading to a dramatic expansion of arid regions in recent decades. Ephemeral plants are crucial herbs in this

Boreal fire records in Northern Hemisphere ice cores: a review [PDF]

open access: yesClimate of the Past, 2016
Here, we review different attempts made since the early 1990s to reconstruct past forest fire activity using chemical signals recorded in ice cores extracted from the Greenland ice sheet and a few mid-northern latitude, high-elevation glaciers.

On the stability of the atmosphere-vegetation system in the Sahara/Sahel region [PDF]

open access: yes, 1998
A conceptual model has been developed for the analysis of atmosphere-vegetation interaction in subtropical deserts. The model can exhibit multiple stable states-in the system: a "desert" equilibrium with low precipitation and absent vegetation and a ...

Spatial Homogenization Adjustment and Application of Weather Station Networks in Xinjiang, China

open access: yesAtmosphere, 2022
In this study, we define the S0 value (buffer zone area centred on a meteorological station) and two inhomogeneity measurement parameters, the station domain area and station network density, for 89 weather stations in the Xinjiang region, and we ...

Technical solutions to prevent heat stress induced crop growth reduction for three climatic regions in Mexico [PDF]

open access: yes, 2008
In the last 15 years a significant increase in greenhouse area has occurred in Mexico, from a modest 50 hectares in 1990 to over 2,000 hectares in 2004. The rapid increase in greenhouse area is a result of an attractive export market, USA. Mexican summer

Spatial and Temporal Changes in the Normalized Difference Vegetation Index and Their Driving Factors in the Desert/Grassland Biome Transition Zone of the Sahel Region of Africa

open access: yesRemote Sensing, 2020
The ecological system of the desert/grassland biome transition zone is fragile and extremely sensitive to climate change and human activities. Analyzing the relationships between vegetation, climate factors (precipitation and temperature), and human ...
