Species richness and intraspecific variation interactively shape marine diatom community functioning

Limnology and Oceanography Letters
Biodiversity generally increases productivity in ecosystems; however, this is mediated by the specific functional traits that come with biodiversity loss or gain and how these traits interact with environmental conditions.

Destruction of Plankton using Cavitating Jet

Journal of Fluid Science and Technology, 2008
This paper presents the experimental result of the destruction of plankton using a cavitating jet generated by a two-dimensional nozzle. The destruction rate of plankton increased with the jet velocity and it reached almost 100% when the nozzle velocity ...

Seasonal patterns of phytoplankton photoacclimation in a dimictic oligotrophic lake over 5 yr: Implications for chlorophyll as an estimate of biomass

Limnology and Oceanography, EarlyView.
Abstract Chlorophyll a is commonly used as a surrogate for algal biomass in lakes and oceans even though phytoplankton can readily adjust intracellular chlorophyll concentration to changes in the environment through a cellular process termed photoacclimation.

Bioluminescent Plankton

Those that are lucky enough to have seen a bioluminescent beach say it is a fantastic spectacle, like few on Earth. The sparks of blue or green light that accompany the water in the winding breaking of the waves captivate young and old alike. I, unfortunately, have never seen it, although I have seen occasional sparks in the night water, and I have ...

Temporal evolution of plankton and particles distribution across a mesoscale front during the spring bloom

Limnology and Oceanography, EarlyView.
Abstract The effect of mesoscale features on the distribution of planktonic organisms are well documented. Yet, the interaction between these spatial features and the temporal scale, which can result in sudden increases of the planktonic biomass, is less known and not described at high resolution.

Plankton: the paradox and the power law [PDF]

arXiv, 2017
Two basic features of assemblages of unicellular plankton: (1) their high biodiversity and (2) the power-law structure of their abundance, can be explained by an allometric scaling of cell growth and mortality with respect to cell size. To show this, we describe a numerical study of a size-structured, multispecies, population-dynamic model; the model ...

Planktons In Aquaculture

, 2023
Abstract Plankton play a crucial role in aquaculture systems, serving as a fundamental component of the aquatic food chain and providing a source of nutrition for many farmed organisms. Plankton, including both phytoplankton (microscopic plants) and zooplankton (microscopic animals), serve as primary producers in aquatic ecosystems.

Concurrent DNA meta‐barcoding and plankton imaging reveal novel parasitic infection and competition in a diatom

Limnology and Oceanography, EarlyView.
Abstract Little is known about diatom parasitism in marine systems. Guinardia delicatula, a biomass‐dominant diatom on the Northeast US Shelf (NES), is regularly parasitized by the protistan nanoflagellate, Cryothecomonas aestivalis in this region. While G.

Active Displacement of a Unique Diatom–Ciliate Symbiotic Association

Fluids
Adaptive movement in response to individual interactions represents a fundamental evolutionary solution found by both unicellular organisms and metazoans to avoid predators, search for resources or conspecifics for mating, and engage in other ...
