Brown and red algae from the Southern Baltic Sea. A key to the identification of the species. 2021. 84 line drawings. 10 col. pls. 102 p. Paper bd. - In English, with Latin nomenclature.

This handbook will be a very useful tool for people interested in marine macroalgae (Rhodophyta and Phaeophyceae), especially for those from the Southern Baltic and the Gulf of Gdañsk. Baltic Sea with its low salinity and its dominant sandy bottom hosts very interesting communities and species whose identification will be eased with the keys, drawings and pictures. The glossary will also help to understand the botanic terms needed for the accurate description and identification of the species and the references will help to complete contextualization. The environmental characteristics of this peculiar sea explain the low diversity of the algae communities in this area and the pauperization observed in thalli. The experience in algae research of the authors eases the approach to the phycological knowledge of these communities. This work fills the gap of these kind of books which are essential for approaching amateurs, beginners and researchers to regional floras of algae contributing to people implication in citizen science and environmental monitoring which may be important for instance for control of invasive or endangered species.
