The purpose of this study was to evaluate the species-environment relationships in arid and semi-arid rangelandsof Nodushan, Yazd. The plant species cover and the environmental variables were measured at 9 sites. Soil sampleswere taken for measurement of 12 attributes in 0-10 cm and 10-80 cm layers. Vegetation was classified using twowayindicator species analysis (TWINSPAN). Data was analyzed u...

Objective: Ecosystems with mixed species compared to the ones with pure compositions provide a broader range of options in the fields of biodiversity, conservation, protection and restoration. Nearly all forest plantations are established as monocultures, but research has shown that there are potential advantages to be gained by using carefully designed species mixtures in place of monocultures...

One of the greatest challenges for ecological restoration is to create or reassemble plant communities that are resistant to invasion by exotic species. We examine how concepts pertaining to the assembly of plant communities can be used to strengthen resistance to invasion in restored communities. Community ecology theory predicts that an invasive species will be unlikely to establish if there ...

Streams and their riparian zones provide typical examples of naturally speciesrich, dynamic habitats. Under natural conditions, spatial and temporal variation in flooding disturbance coincide with a strong hydrological gradient from the channel to the uplands, generating a heterogeneous environment with corresponding high plant and animal diversity. Yet, streams and their riparian zones are hig...

green plants have emerged as ideal platforms for production of recombinant vaccine during recent decades. various antigens relating to a large number of animal and human diseases have been studied in different plant species for production of recombinant vaccines. despite the unique advantages of plant systems as green factories for production of recombinant vaccines, there are some major hurdle...

Recovering biodiversity is a common goal of restoration, yet outcomes for animal communities are highly variable. A major reason this variability may be that active restoration efforts typically target plant communities, with the assumption will passively recover in turn. However, remains largely unvalidated experimentally making it unclear how plant‐focused strategies influence communities. We...

In Mediterranean regions and other areas with variable climates, interannual weather variability may impact ecosystem dynamics, and by extension ecological restoration projects. Conditions at reference sites, which are often used to evaluate restoration projects, may also be influenced by weather variability, confounding interpretations of restoration outcomes. To better understand the influenc...
