Hildenbrandia rivularis (Rhodophyta) in central Poland

Joanna Żelazna-Wieczorek, Maciej Ziułkiewicz


Freshwater red algae Hildenbrandia rivularis has been noted for the first time in central Poland near the Lodz agglomeration. Until now, this alga was recorded only in mountain and Polish Lowland areas. The wide range of habitat conditions influencing the occurrence for this protected species has been determined in the spring niche. The possible threat to habitat where H. rivularis occurs, is connected with construction and exploitation of the A2 highway.
