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 ...
Botanical Composition and Species Diversity of Arid and Desert Rangelands in Tataouine, Tunisia
Natural rangelands occupy about 5.5 million hectares of Tunisia’s landmass, and 38% of this area is in Tataouine governorate. Although efforts towards natural restoration are increasing rapidly as a result of restoration ...
Grasslands in 'Old World' and 'New World' Mediterranean-climate zones: past trends, current status and future research priorities
Despite their ecological, economic and social importance,
grasslands in areas with Mediterranean climates
continue to receive limited scientific, political and
media attention. The main objectives of this review
are to ...
Alien plants are less palatable to pest herbivores than native plants: evidence from cafeteria experiments in search of suitable plant species to restore degraded ecosystems
Nowadays, the ecology and evolutionary potential of alien species are the subjects of several ecological studies. The goal of this study was to compare the feeding preference of Arion ater on seedlings and leaves of alien ...
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 ...
Antifungal activity of essential oil from Tunisian myrtle (Myrtus communis L.)
The objective of this study was to investigate the antifungal essential oil activity. The InVitro antifungal activity of myrtle essential oil against seven fungi allowed us to specify the corresponding minimum inhibition ...
Morphological characterization of cactus pear (Opuntia ficus-indica) accessions from Agadir, Morocco
Proceeding paper on Morphological characterization of cactus pear (Opuntia ficus-indica) accessions from Agadir, Morocco:
The North Africa region falls under an arid or semi-arid climate and is considered as a hot spot ...
Rangeland Biodiversity and Climate Variability
Rangeland biodiversity related closely with climate variability. Rainfall plays an important role in arid
rangeland restoration. Under favorable conditions, one-year grazing exclusion considerably enhanced
species richness ...
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 ...
