The Relationship

Ten taxa of freshwater red algae have been observed in a survey of 62 streams and rivers within southern Ontario, Canada, over a period of 3 years. Five species are additions to the flora of Canada, Chroodactylon ramosum, Boldia erythrosiphon, Sirodotia tenuissima, Batrachospermum densum, and B. ectocarpum. In addition to these algae, Audouinella violacea, Sirodotia suecia, and Tuomeya fluviatilis are new observations within Ontario.Most of the Ontario red algae are restricted to streams or rivers with a minimum average flow rate of 10 m min−1. Audouinella violacea, B. moniliforme, and Lemanea fucina occur in a large number of streams which have a wide pH and conductivity range whereas S. tenuissima and B. ectocarpum are confined to one of the sites examined.Ultrastructural findings are reported concerning the cell organization of Boldia as well as the relationship between Batrachospermum plants and the "chantransia" stage. A key to the 10 taxa is included plus descriptions and a list of epiphytes of each alga are presented.

First Time

Freshwater red algae <em>Hildenbrandia rivularis</em> 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 <em>H. rivularis</em> occurs, is connected with construction and exploitation of the A2 highway.

AbstractThere were only less than sixty records of freshwater red algae in Finland until the 1980s, when the author began sampling the running waters of southern and central Finland; 516 new records were made in 1984–2011. More intensive research began in 2012, with a few field teams working at first in Central Finland Province and then covering the whole country. The project continued until 2018. During these studies approximately 3400 new locations were investigated and 3641 new records of 29 taxa were made. Since 2013, 12 ecological variables have also been measured or estimated. The share of positive records from the studied locations varied from 49% to 86% (avg. 72%), being highest in Lapland (85.5%). The most frequent taxa were Batrachospermum gelatinosum (36.5%), Audouinella hermannii (14.5%), Sheathia arcuata (9.3%), Sirodotia suecica (8.4%), Audouinella chalybea (4.7%), Lemanea fluviatilis (3.8%) and Lemanea fucina (2.8%). Batrachospermum elegans, Kumanoa virgatodecaisneana and Lemanea mamillosa occurred in southwestern Finland in waters with higher conductivity, whereas Batrachospermum turfosum and Virescentia vogesiaca were typical taxa of acidic and soft water. Batrachospermum sporulans and Lemanea condensata occurred only in northern Finland. Some records did not fit the recent morphological keys and should be analysed using molecular methods.
