While numerous studies have explored effect community diversity structure on invasion success, a systematic comparative analysis system robustness between antagonistic mutualistic networks from metacommunity persp...

the introduction of acacia saligna in the north nile delta of egypt is causing harmful impacts on the plant diversity. thirty stands were established in both invaded and non-invaded areas. the species abundance and diversity were determined. soil samples were collected and analyzed. the correlation between vegetation and soil variables was investigated. the allelopathic potential of water and m...
