Journal of Phycology, EarlyView.Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

A satellite view of the space-time variability of phytoplankton biomass in the Mediterranean Sea [PDF]
, 2010 The general thesis objective is to determine, with sufficient accuracy (i.e. using the most reliable datasets and techniques) the phytoplankton space time variability in the Mediterranean Sea (MED) using satellite data (SeaWiFS), at different timescales,

Journal of Phycology, EarlyView.Abstract Cyanotoxins such as microcystin (MC), cylindrospermopsin, and saxitoxin are secondary metabolites that are rich in nitrogen (N). Most cyanobacteria grow best on reduced inorganic N (ammonium, NH4), but when NH4 is absent, cyanobacteria can activate physiological pathways to process other N forms (e.g., nitrate; NO3).

Journal of Phycology, EarlyView.Abstract The genus Skeletonema is a dominant diatom in coastal waters worldwide, frequently causing blooms, and it includes several cryptic species. To elucidate the occurrence patterns and niche differentiation among Skeletonema species in Tokyo Bay, Japan, sampling was conducted between June 2021 and February 2023.

Journal of Zoology, EarlyView.In social birds such as flamingos, intraspecific interactions are frequent and play a key role in flock cohesion, communication, and the establishment of social networks. Understanding the patterns and drivers of these interactions can provide valuable ecological insights and inform management, husbandry, and conservation practices.

Characterization of phytoplankton species in oyster habitats in Cape Breton, Nova Scotia
Phytoplankton is the base of marine food webs and all marine life depends on it for survival. This study identified phytoplankton species found in the water of the Bras d’Or Lake and in oyster gut contents using DNA sequencing and performed a fatty acid ...

Seasonal patterns and interannual variability of phytoplankton in Lake Stechlin
, 2004 The paper presents results of detailed phytoplankton investigations in Lake Stechlin between 1994 and 2003. The analysis includes the picoplankton fraction (dominated by Cyanobium sp.) that regularly appears as a deep-layer chlorophyll maximum (DCM ...

Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus
New Phytologist, EarlyView.Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...
