Prokaryotic and Eukaryotic Community Succession and Potential Parasitic Interactions During Two Alexandrium pacificum Blooms in Aotearoa New Zealand

Toxins
Harmful algal blooms (HABs), caused by the dinoflagellate Alexandrium pacificum, are increasingly frequent in the Marlborough Sounds, an important aquaculture region in Aotearoa New Zealand.

Toxic and non-toxic dinoflagellates host distinct bacterial communities in their phycospheres

Communications Earth & Environment, 2023
Dinoflagellates encompass highly abundant and diverse toxin-producing species among marine phytoplankton. Previous works suggested that some bacterial taxa may affect toxins production in dinoflagellates, however, little is known about impact of toxic ...

Differences in the chemical composition of organic-walled dinoflagellate resting cysts from phototrophic and heterotrophic dinoflagellates [PDF]

, 2013
Dinoflagellates constitute a large proportion of the planktonic biomass from marine to freshwater environments. Some species produce a preservable organic-walled resting cyst (dinocyst) during the sexual phase of their life cycle that is an important ...

Comparative analysis of canonical and noncanonical rhodopsins in Amphidinium carterae and Karlodinium veneficum

Journal of Phycology, EarlyView.
Abstract Rhodopsins are ancient and versatile light‐sensitive proteins, widely distributed across microbial life. In dinoflagellates, however, their diversity and function remain poorly understood, owing to the lineage's extreme genomic divergence. Here, we surveyed the rhodopsin complements of two dinoflagellates, Amphidinium carterae and Karlodinium ...

Variability of planktonic and epiphytic vibrios in a coastal environment affected by Ostreopsis blooms

Scientia Marina, 2016
Vibrios include several pathogenic bacteria that occur in aquatic environments. The presence of Vibrio has been assessed in many ecosystems by culture-based techniques.

The feeding ecology of some zooplankters that are important prey items of larval fish [PDF]

, 1984
Diets of 76 species of fish larvae from most oceans of the world were inventoried on the basis of information in 40 published studies. Although certaln geographlc, size- and taxon-specific patterns were apparent, certain zooplankton taxa appeared in the ...

Palynomorphs of brackish and marine species in cores from the freshwater Lake Sapanca, NW Turkey [PDF]

, 2010
Lake Sapanca, which is located on the Sakarya–Sapanca–İzmit corridor in NW Turkey, is a freshwater lake with numerous fish farms in its catchment. Palynological analyses including non-pollen palynomorphs of a short (38.5 cm) and a longer sediment core ...

Unveiling the phylogenetic position of the type species of the syndinean genus Amoebophrya and broad divergence of the A. ceratii complex

Journal of Phycology, EarlyView.
Abstract The syndinean genus Amoebophrya comprises endoparasitic dinoflagellates that infect various marine protists. Since the description of the type species, A. sticholonchae, a parasite of the radiolarian Sticholonche zanclea, an additional six Amoebophrya species have been formally described.

Transformation of Phytoplankton Communities in the High Arctic: Ecological Properties of Species

Diversity
During the 84th cruise of the R/V Akademik Mstislav Keldysh in August 2021, patterns of phytoplankton composition transformation were revealed along a northward gradient. The study involved three transects in the Fram Strait and adjacent Arctic waters: a

Description of two species of early branching dinoflagellates, Psammosa pacifica n. g., n. sp. and P. atlantica n. sp. [PDF]

PLoS ONE, 2012
In alveolate evolution, dinoflagellates have developed many unique features, including the cell that has epicone and hypocone, the undulating transverse flagellum. However, it remains unclear how these features evolved.
