Bangia Atropurpurea

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’.

Bangia Atropurpurea

Bangia atropurpurea was first found on the southwestern shore of Lake Michigan in 1968; by 1976 it had covered suitable substrates on the southern two thirds of the lakeshore. Optimal vegetative growth occurred above the low waterline during the spring and fall, especially near harbor areas. Vegetative growth is initiated from either perennating basal cells or monospores. Bangia contained extraordinarily high concentrations of bromine and zinc, suggesting it requires relatively high levels of halogens and trace metals, which are present in runoff waters and contaminated harbors. Key words: Bangia, invasion, Lake Michigan, halogens, trace metals, algal zonation

The first observation of the red alga Bangia atropurpurea (Bangiales, Rhodophyta) in Serbia was in 1991 in the Trgoviski Timok River (Eastern Serbia). From 1991 to 2017, the species was sporadically observed at four more locations in three hillmountain rivers in Southwestern (the Gvozdacka River and the Raska River) and Eastern (the Nisava River - two localities) Serbia. More intensive research on this alga was carried out from 2017 to 2020, and a total of 220 localities in 132 hillmountain watercourses were studied. Bangia atropurpurea was recorded at six locations in Southwestern and Eastern Serbia. Five of these locations represent new B. atropurpurea localities in Serbia (the Brusnicka River, the Golijska Moravica River, the Panjica River, the Resava River, and the second locality in the Trgoviski Timok River), while one of them is already known from previous studies (the Raska River). The species was found in running, moderately hard and very hard, well-oxygenated, slightly alkaline waters, mainly low in inorganic nutrients, and in highly variable values of temperature and conductivity. Despite the long period since its first observation in Serbian rivers, the species is still known in a small number of localities. The small number of localities, low relative abundance, and various anthropogenic influences affecting its habitats have led the species to be recognized as endangered and strictly protected in Serbia. The intensive development of small hydropower plants which have emerged in recent years may threaten B. atropurpurea habitats.

Bangia Atropurpurea

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.
