In arid and semiarid ecosystems, the potential threats of exotic invasive species are enhanced due to increasing human activities. Biological soil crusts (BSCs), acting as arid ecosystem engineers, may play an important role in preventing the establishment of exotic invasive plants. Our goal was to examine whether BSCs could inhibit the establishment of probable exotic plant species originating...

Variations in morphology and salt spray tolerance were studied among 22 populations of Setaria viridis derived from the coastal inland habitats central Japan to elucidate adaptation species habitats, which are important reservoirs that enhance overall diversity agro-ecosystems. The S. comprised three ecotypes differed plant form tolerance: short, for within rocky cliffs pebble shores; tall, fou...

Weed seed persistence in the soil seedbank is central to weed population dynamics; however, limited knowledge of mechanisms regulating seed survival in soil remains an obstacle to developing seed-bank management practices. Weed seeds are rich in carbon and nitrogen, and therefore may represent an important nutritional resource to soil microbes. The objective of this study was to test the hypoth...

Setaria africana (Yeh, 1959) is represented by two subspecies, Setaria africana africana Troncy, Graber & Thal, 1976 from giant eland (Taurotragus derbianus) from the Central African Republic and Cameroon and Setaria africana farchai Troncy, Graber & Thal, 1976 from bushbuck (Tragelaphus scriptus), also from the Central African Republic. Material collected from nyala (Tragelaphus angasii), bush...
