Geobotanical assessment of taxa with a high percentage of richness and endemism plays an important role on conservation plans. South-West Asia is one of the main biodiversity centers of the genus Onosma (Boraginaceae) comprising a high rate of species richness and endemism in Iran. Due to existing threatened factors to habitats and lack of sufficient data on conservation and distribution patter...

BACKGROUND AND AIMS Crassula hunua and C. ruamahanga have been taxonomically controversial. Here their distinctiveness is assessed so that their taxonomic and conservation status can be clarified. METHODS Populations of these two species were analysed using morphological, chromosomal and DNA sequence data. KEY RESULTS It proved impossible to differentiate between these two species using 12 ...

abstract the syrphidae family (known as hover flies or flower flies) is one of the largest families of diptera with almost 6000 species. adult flies feed on nectar and pollen of flowers and they are crucial agent in pollinating process. the larvae of many species of syrphidae are predators of aphids and play an important role in biological control of pests. in the following faunestic investigat...

The Center for Forest Mycology Research (CFMR) at the Forest Products Laboratory in Madison, WI is one of the few remaining mycological research labs left in the USDA-Forest Service. Traditionally established to study the taxonomy of pathogenic root rot, sap-rot, and heart-rot fungi, the group has changed its focus in recent years towards the biosystematics and ecology of both pathogenic and sa...

BACKGROUND The common or brinjal eggplant (Solanum melongena L.) belongs to the Leptostemonum Clade (the "spiny" solanums) of the species-rich genus Solanum (Solanaceae). Unlike most of the genus, the eggplant and its relatives are from the Old World; most eggplant wild relatives are from Africa. An informal system for naming eggplant wild relatives largely based on crossing and other biosystem...
