Bangia atropurpurea was found at two new localities in the Nisava River (Southern Serbia). In Serbia, this species is endangered. It has been found so far in the Trgoviski Timok River, the Gvozdovacka River and the Raska River. With the two new localities in the Nisava 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.

Samples of the freshwater red algae, Bangiadulcis atropurpurea, collected from the mountain waterfalls and its close species, Bangia fuscopurpurea, collected from coasts, were phylogenetically analyzed. The sequences of the rbcL gene and RuBisCO spacer region of the freshwater Bangiadulcis atropurpurea species were identical or similar to those of B. atropurpurea from Japan, North America and Europe. This result indicated that the freshwater Bangiadulcis species from Taiwan shared a common ancestor with the three above-mentioned populations and formed a distinct clade from the marine Bangia species in the phylogenetic trees. It is suggested that all the previous records on marine Bangia species should be revised and the name B. fuscopurpurea be used for the marine species in Taiwan. In this study, the freshwater alga B. atropurpurea presents a new record in the algal flora of Taiwan. This finding is important for the protection of the biodiversity of red algal flora, and provides useful information on the ecological conservation of the species in Taiwan.

AbstractKathirithamby, J. & Grimaldi, D.: Remarkable stasis in some Lower Tertiary parasitoids: descriptions, new records, and review of Strepsiptera in the Oligo-Miocene amber of the Dominican Republic. Ent. scand. 24: 31-41. Copenhagen, Denmark. April 1993. ISSN 0013-8711. 25-30 million years of parasite stasis is recorded in amber from the Dominican Republic, by the finding of a species of strepsipteran morphologically indistinguishable from Bohartilla melagognatha Kinzelbach, 1969 (Bohartillidae), and two species very close to Caenocholax fenyesi (Pierce 1909) (Myrmecolacidae). A new record is made of a species previously described from Dominican amber, Myrmecolax glaesi Kinzelbach, 1983. The history of the Tertiary strepsipteran fauna is discussed. Minimal ages of taxa are extrapolated based on these amber and other fossils, higher-level cladistic relationships, and fossil dating of major host groups. These new findings are consistent with Kinzelbach's hypotheses of an ancient, Lower Cretaceous/Jurassic origin of the Strepsiptera.

A Bornean red algal population of Laurencia simlis Nam et Saito was analyzed for its secondary metabolite composition. Seven compounds were identified: ent -1(10)-aristolen-9β-ol (1), (+)-aristolone (2), axinysone B (3), 9-aristolen-1α-ol (4), 2,3,5,6-tetrabromoindole (5), 1-methyl-2,3,5,6-tetrabromoindole (6), and 1-methyl-2,3,5-tribromoindole (7). Compound 1 was identified as a new optical isomer of 1(10)-aristolen-9β-ol. Compounds 1, 4 and 5 exhibited good antibacterial activity against antibiotic resistant clinical bacteria and cytotoxic effects against selected cancer cell lines.

The amino acid sequence of the ferrodoxin of Porphyra umbilicalis was determined by the dansyl-phenyl isothiocyanate method, on peptides obtained by tryptic, chymotryptic and thermolytic digestion of the protein or its CNBr-cleavage fragments. The molecule consists of 98 residues, has an unblocked N-terminus and shows considerable similarity with other plant-type ferredoxins. It is the first reported sequence of a red-algal ferredoxin.

Upon review of the reference data and the author's herbarium specimens were recorded five species of the Skeletocutis genus in the Ukrainian Left Bank Forest Steppe. One species, S. brevispora, is a new record for Ukraine, another one, S. carneogrisea, was found for the first time in the Ukrainian Left Bank Forest Steppe. For other two species, S. nivea, S. subincarnata, new localities were found within the studied region.

The red alga ‘Bangia’ sp. ESS1, a ‘Bangia’ 2 clade member, responds to heat stress via accelerated asexual reproduction and acquires thermotolerance based on heat-stress memory. However, whether these strategies are specific to ‘Bangia’ 2, especially ‘Bangia’ sp. ESS1, or whether they are employed by all ‘Bangia’ species is currently unknown. Here, we examined the heat-stress responses of ‘Bangia’ sp. ESS2, a newly identified ‘Bangia’ clade 3 member, and Bangia atropurpurea. Intrinsic thermotolerance differed among species: Whereas ‘Bangia’ sp. ESS1 survived at 30 °C for 7 days, ‘Bangia’ sp. ESS2 and B. atropurpurea did not, with B. atropurpurea showing the highest heat sensitivity. Under sublethal heat stress, the release of asexual spores was highly repressed in ‘Bangia’ sp. ESS2 and completely repressed in B. atropurpurea, whereas it was enhanced in ‘Bangia’ sp. ESS1. ‘Bangia’ sp. ESS2 failed to acquire heat-stress tolerance under sublethal heat-stress conditions, whereas the acquisition of heat tolerance by priming with sublethal high temperatures was observed in both B. atropurpurea and ‘Bangia’ sp. ESS1. Finally, unlike ‘Bangia’ sp. ESS1, neither ‘Bangia’ sp. ESS2 nor B. atropurpurea acquired heat-stress memory. These findings provide insights into the diverse heat-stress response strategies among species from different clades of ‘Bangia’.
