Diatoms of Acadia National Park, Maine, USA, with a detailed account on taxonomy and morphology of several remarkable species
VESELÁ, Jana
This thesis was focused on studying diatoms (Bacillariophyceae) from Acadia National Park, Maine, USA. First, the park is introduced and the preliminary study of freshwater algae, including diatoms, is presented. Extraordinary species richness of algae was discovered, especially in the group of diatoms, which is documented by a complete list of 674 diatom taxa in 92 genera encountered in the freshwater and brackish habitats within the park. Of those a considerable number of species unfortunately remained unidentified, as they did not conform to any described taxon in the available scientific literature. Therefore, several of those unnamed taxa were studied in close detail using light and scanning electron microscopes, exhaustive literature and herbaria search, and yielded description of three new species from genus Eunotia, and rediscovery of two rare and almost forgotten Surirella species.

The algal flora of Acadia National Park, Maine
VESELÁ, Jana
This study presents freshwater and brackish algal flora of Acadia National Park, Maine, U.S.A., a small park on the coast of New England. Prior to this study, there has been no examination conducted on freshwater and brackish algae restricted to the park boundaries. Over 200 samples, from 119 localities within the park, were collected and examined using standard microscopic techniques. A total of 160 genera of algae (from 12 algal phyla) were observed in the samples, including 140 new generic records for the park. Based on the similar studies, the high number of occurring algal genera in the park indicates an exceptionally high diversity for an area of this size.

The diatoms of Acadia National Park, Maine, with a detailed account of the Eunotiophycidae
VESELÁ, Jana
Taxonomy of diatoms (Bacillariophyceae) was studied in 45 samples from Acadia National Park, Maine, U.S.A. Approximately 550 diatom taxa in 87 genera were observed in the samples from various habitats (i.e., lakes, streams, wetlands, wetwalls and brackish habitats). The most species rich group of diatoms, Eunotiophycidae, was studied in detail, resulting in a detailed documentation of 81 species and varieties with 18 probably new taxa.
