Dinoflagellate blooms are generally unpredictable, short, with low species diversity, and with little species succession. [73] The low species diversity can be due to multiple factors. One way a lack of diversity may occur in a bloom is through a reduction in predation and a decreased competition.
Some dinoflagellates have further switched to dinoflagellate histone-like proteins (HLPs) for packaging. [3] The version of DVNPs in dinoflagellates have a variable N-terminal tail with a nuclear localization signal. It also has many phosphorylation sites, a feature not seen in viral counterparts. The fixed C-terminal domain may have a helix ...
The marine dinoflagellate genus Gambierdiscus occurs globally in tropic and subtropic regions. It mainly grows attached to macroalgae and coralline turfalgae. Thus, it does not form visible surface blooms like many other harmful dinoflagellate species (red tides).
The term presently does not imply any specific relationship or classification of the organisms that possess flagella. However, several derivations of the term "flagellate" (such as " dinoflagellate " and " choanoflagellata ") are more formally characterized.
The etymology of this genus name comes from Greek, Dino comes from "deinos" (δεινός) [7] meaning terrible [8] and "physis" (φύσις) meaning nature.[9]The genus was first described in 1839 by Ehrenberg, which is why the holotype species of this genus is Dinophysis acuta Ehrenberg. [5]
Dinokaryota is a main grouping of dinoflagellates.They include all species where the nucleus remains a dinokaryon throughout the entire cell cycle, which is typically dominated by the haploid stage.
While humans wouldn’t be very happy to find that organisms were growing on their skin, particularly fungi, algae, and insects, it works out pretty well for sloths. Sloths may be hosting entire ...
Karenia brevis has an optimum temperature range of 22–28 °C (72–82 °F), [8] an optimum salinity range of 25-45 Practical Salinity Units (PSU), [9] has adapted to "low-irradiance environments," and can utilize both organic and inorganic nitrogen and phosphorus compounds to survive. [10]
