The article presents the results of morphological and anatomical analysis Cystoseira sensu lato taxa in flora Ukraine, taking into account modern views on nomenclature genus. Earlier, based molecular phylogenetic analysis, it was shown that along Ukrainian shores polyphyletic genus s. l. is represented by three (Ericaria crinita f. bosphorica (Sauvageau) S.S.Sadogurska, J.Neiva et A.Israel., Go...

This study's objective was to develop a model determine dye adsorption efficiency of Treptacantha barbata (Stackhouse) Orellana& Sansón, 2019 (formerly Cystoseira C. Agardh, 1820). During the experiments, treatment groups, such as initial Methylene Blue (MB) concentration (0.1-10.0 mg L-1), contact time (5 1440 min) and adsorbent dosage (0.1-2 g) were applied. Scanning electron microscopy, ...

Lyonetia ledi Wocke, 1859 (Lyonetiidae), was hitherto considered as a boreal species with circumpolar distribution pattern and relict populations in isolated peat bogs north-east of the Alps (Austria, Czech Republic, Germany). In Europe it is known leaf-miner on Rhododendron tomentosum Stokes ex Harmaja (Ericaceae) primary host-plant also Myrica gale L. (Myricaceae). The first record from Swiss...

Analyses of a sediment core from Highstead Swamp in southwestern Connecticut, USA, reveal Lateglacial and early Holocene ecological and hydrological changes. Lateglacial pollen assemblages are dominated by Picea and Pinus subg. Pinus, and the onset of the Younger Dryas (YD) cold interval is evidenced by higher abundance of Abies and Alnus viridis subsp. crispa. As climate warmed at the end of t...
