New record of endangered red alga Bangia atropurpurea (A. Roth) C. Aardh (Bangiales, Rhodophyta) in the Nišava River, Serbia

Abstract

Bangia atropurpurea was found at two new localities in the Nišava River (Southern Serbia). In Serbia, this species is endangered. It has been found so far in the Trgoviški Timok River, the Gvozdovačka River and the Raška River. With the two new localities in the Nišava River, at present Bangia occupies four rivers (five localities). New findings are important for the protection of the biodiversity of red algal flora in the region, and provide useful information on the ecological preferences of the species in Serbia.
