Is long-term protection useful for the regeneration of disturbed plant communities in dry areas?
In dry areas, natural plant communities are mainly affected by climatic stress and human disturbances – overgrazing, ploughing and biomass harvesting – that accelerate their degradation. Management techniques, including ...
Measurement of the aboveground biomass of some rangeland species using a digital nondestructive technique
Plant biomass is usually assumed to be positively correlated with canopy cover. Measurements of
canopy cover can now be easily and precisely made through image processing of high-resolution
digital photography. This study ...
Potential distribution and the habitat suitability of the African mustard (Brassica tournefortii) in Tunisia in the context of climate change
The global warming resulting from anthropogenic activities is considered a major threat for the biodiversity in arid and semi-arid regions worldwide. North African countries in western Mediterranean basin, including Tunisia, ...
Effect of protection on plant community dynamics in the Mediterranean arid zone of southern Tunisia: a case study from Bou Hedma national park
Ecosystems protected from heavy grazing impacts, such as national parks and refuges, are generally considered to sustain higher plant species diversity and better ecosystem composition and structure compared to heavily ...
Unveiling soil degradation and desertification risk in the Mediterranean basin: a data mining analysis of the relationships between biophysical and socioeconomic factors in agro-forest landscapes
Soil degradation and desertification processes in the Mediterranean basin reflect the
interplay between environmental and socioeconomic drivers. An approach to evaluate
comparatively the multiple relationships between ...
Response of Stipa lagascae R. and Sch. to Protection under Arid Condition of Southern Tunisia
The study was carried out at two sites (Menzel Habib and national park of Sidi Toui) of southern Tunisia which provided an aridity gradient to evaluate the effect of long term protection on the regeneration of Stipa lagascae ...
The vulnerability of native rangeland plant species to global climate change in the West Asia and North African regions
This study aimed to evaluate the impact of climate change on the geographical
distribution of selected native species from two areas from West Asia and North Africa.
Three species representing two genera were selected for ...
Vegetation dynamics under variable conditions in the famous sandy steppe of southern Tunisia
During last decades, the natural vegetation cover in
southern Tunisia, mainly dominated by dwarf and sparse
shrub, was continuously disturbed under various human
activities especially on sandy soil (easily eroded). ...
Physiological, anatomical and antioxidant responses to salinity in the Mediterranean pastoral grass plant Stipa lagascae
Soil and water salinity is a major environmental problem in the dry Mediterranean regions, affecting rangeland production. This study investigated the effects of salinity on the wild perennial grass (Poaceae) species Stipa ...
Diversity of desert rangelands of Tunisia
Plants are important components of any rangeland. However, the importance of desert rangeland plant diversity has often been underestimated. It has been argued that desert rangelands of Tunisia in good ecological condition ...
