Phylogenetic structure and formation mechanism of shrub communities in arid and semiarid areas of the Mongolian Plateau [PDF]

open access: yes, 2019
The mechanisms of species coexistence within a community have always been the focus in ecological research. Community phylogenetic structure reflects the relationship of historical processes, regional environments, and interactions between species, and ...

Drought monitoring in the Brazilian Semiarid region [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2019
Drought is a natural and recurrent phenomenon. It is considered 'a natural disaster' whenever it occurs in an intensive manner in highly populated regions, resulting in significant damage (material and human) and loss (socioeconomic). This paper presents the efforts developed to monitor the impact of drought in the semiarid region of Northeast Brazil ...

Multi-objective optimisation of bio-based thermal insulation materials in building envelopes considering condensation risk [PDF]

open access: yes, 2018
The reduction in energy demand for heating and cooling with insulation materials increases the material related environmental impact. Thus, implementing low embodied energy materials may equilibrate this trade-off.

Stochastic soil water dynamics of phreatophyte vegetation with dimorphic root systems [PDF]

open access: yes, 2009
As the direct uptake of deep groundwater by vegetation may be essential in semiarid regions, we incorporated this process in stochastic root zone water balance models.

Assessing water availability in Mediterranean regions affected by water conflicts through MODIS data time series analysis [PDF]

open access: yes, 2019
Water scarcity is a widespread problem in arid and semi-arid regions such as the western Mediterranean coastal areas. The irregularity of the precipitation generates frequent droughts that exacerbate the conflicts among agriculture, water supply and ...
