Permanent monitoring sites in Flat Top Hill Conservation Area in Central Otago were resurveyed in the spring of 1997, following a four-year interval in which rabbit numbers had been very low, and stock absent. All study sites showed considerable vegetation change between 1993 and 1997. The most significant changes in the vegetation were large increases in overall vascular species richness and d...

This study aimed to reveal the diversity of aphid species and aphid-plant interactions adjacent Çardak Lagoon, which is close agricultural areas in Çanakkale Province Turkey. Twenty-seven belonging 17 genera three subfamilies from Aphididae (Hemiptera) were identified. Of these, Staticobium latifoliae (Bozhko, 1950) new record genus Mordvilko, 1914 Aphis symphyti Schrank, 1801 are records for f...

Italy is recognized as one of the prominent hot spot areas for plant diversity at regional and global scale, hosting a rich range of ecosystems and habitat types. This is especially true considering aquatic habitats, which represent a major portion of the total water surfaces in the Mediterranean region. Nevertheless, only a scant attention was paid to clarify the species richness of aquatic pl...

Invasive species are threatening the diverse habitats within Pictured Rocks National Lakeshore in the Upper Peninsula of Michigan. The invasive exotics burdock (Arctium minus), bishop’s goutweed (Aegopodium podgraria), forget-me-not (Myosotis spp.), garlic mustard (Alliaria petiolata), periwinkle (Vinca spp.), red clover (Trifolium pratense), spotted knapweed (Centaurea maculosa), and sweet clo...

Extraction and study of the optical properties natural dyes from several plant parts such as leaves, flowers, tubers, fruits have been carried out using a simple maceration method UV-Vis absorption characterization. The samples were divided into groups in this study, namely flower group (Tagetes sp., Paeonia Centaure Chrysanthemum Carthamus tinctorius, Gomphrena globosa, Myosotis sylvatica, Lav...

Plant-soil feedback (PSF) and plant competition play an important role in structuring vegetation composition, but their interaction remains unclear. Recent studies suggest that competing plants could dilute pathogenic effects, whereas the standing view is that competition may increase the sensitivity of the focal plant to PSF. In agro-ecosystems each of these two options would yield contrasting...
