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

open access: yesCommunications 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 ...

Fresh-water dinoflagellates of Maryland [PDF]

open access: yes, 1947
Collections were made in the summer of 1942 and again at different times in 1946 and 1947. Some collections were not sufficient in numbers to allow for proper identification, so the present paper does not give a complete list.

[Corrigendum to] Effects of small-scale turbulence on lower trophic levels under different nutrient conditions [vol 32, pg 197, 2010] [PDF]

open access: yes, 2009
Small-scale turbulence affects the pelagic food web and energy flow in marine systems and the impact is related to nutrient conditions and the assemblage of organisms present.

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

open access: yesScientia 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.

Insights into a dinoflagellate genome through expressed sequence tag analysis [PDF]

open access: yes, 2005
BACKGROUND: Dinoflagellates are important marine primary producers and grazers and cause toxic "red tides". These taxa are characterized by many unique features such as immense genomes, the absence of nucleosomes, and photosynthetic organelles (plastids)

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

open access: yesDiversity
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]

open access: yesPLoS 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.

Pigment and fatty acid profiling reveal differences in epiphytic microphytes among tropical Thalassodendron ciliatum meadows

open access: yes, 2020
Tropical seagrasses support abundant and diverse epiphytic microalgae that form the base of seagrass food webs. To help better understand the influence of structural variability of tropical seagrass meadows on associated microalgal epiphytes, we ...

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

open access: yes, 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 ...

Integrating functional diversity, food web processes, and biogeochemical carbon fluxes into a conceptual approach for modeling the upper ocean in a high-CO2 world [PDF]

open access: yes, 2005
Marine food webs influence climate by channeling carbon below the permanent pycnocline, where it can be sequestered. Because most of the organic matter exported from the euphotic zone is remineralized within the "upper ocean" (i.e., the water column ...
