Representatives of the Achnanthidium minutissimum complex have been studied from Transbaikal region, Russia. The region is known for its unique algal flora and high levels endemism. Despite group monoraphid diatoms being quite extensively in this recent years, only four species reported so far. Three new are described based on LM SEM microphotographs molecular data: baicalonanum sp. nov., A. ob...

Cyanobacterial harmful algal blooms (cyanoHABs) are a primary source of water quality degradation in eutrophic lakes. The occurrence of cyanoHABs is ubiquitous and expected to increase with current climate and land use change scenarios. However, it is currently unknown what environmental parameters are important for indicating the presence of cyanoHAB toxins making them difficult to predict or ...

The human-mediated translocation of species poses a distinct threat to nature, human health, and economy. Although existing models calculate the invasion probability of any species, frameworks for species-specific forecasts are still missing. Here, we developed a model approach using global ship movements and environmental conditions to simulate the successive global spread of marine alien spec...

Harmful algal blooms (HABs) degrade water quality and produce toxins. The spatial distribution of HAbs may change rapidly due to variations wind, water currents, and population dynamics. Risk assessments, based on traditional sampling methods, are hampered by the sparseness of water sample data points, and delays between sampling and the availability of results. There is a need for local risk a...

Morphology, taxonomy, and nomenclature of three species of Hawaiian green algae (Chlorophyta) are examined. Udotea? abbreviata Gilbert is shown to be incorrectly placed in that genus and more appropriately allied to Pseudochlorodesmis. The complex nomenclatural relationships of Cladophora tildeniae Brand in Tilden, Cladophora tildeniae Brand, and Cladophora hawaiiana Tilden are described, with ...
