Overlooked components of lipid metabolism: Odd-chain polyunsaturated fatty acids in photosynthetic microorganisms. [PDF]

J Phycol
Abstract This mini‐review examines odd‐carbon polyunsaturated fatty acids (odd‐PUFAs), a rare but biologically significant group of fatty acids in photosynthetic microorganisms. Odd‐PUFAs are straight‐chain fatty acids containing an odd number of carbon atoms and two or more methylene‐interrupted double bonds. They typically account for less than 1% of

Molecular approaches for identification and quantification of harmful dinoflagellates [PDF]

, 2017
In recent years, harmful algal blooms caused by dinoflagellates have become increasingly common in coastal waters throughout the world, causing negative impacts on human health, ecosystem quality and also affecting economic and commercial activities ...

Dinoflagellate–Bacteria Interactions: Physiology, Ecology, and Evolution

Biology
Dinoflagellates and heterotrophic bacteria are two major micro-organism groups within marine ecosystems. Their coexistence has led to a co-evolutionary relationship characterized by intricate interactions that not only alter their individual behaviors ...

Circadian Rhythms in Dinoflagellates: What Is the Purpose of Synthesis and Destruction of Proteins?

Microorganisms, 2013
There is a prominent circadian rhythm of bioluminescence in many species of light-emitting dinoflagellates. In Lingulodinium polyedrum a daily synthesis and destruction of proteins is used to regulate activity.

Responses of primary producers, anoxia, and chemical feedback to Late Glacial climate change: Insights from a paired lake approach

Journal of Quaternary Science, EarlyView.
Abstract Worldwide, lacustrine ecosystems are threatened by eutrophication and deoxygenation. Both processes are driven by the combined effects of human activities and climate change. Understanding the pre‐anthropogenic nexus between warming, eutrophication, deoxygenation, and related feedback is essential to determine how lakes respond to rapid ...

Physiological and molecular responses of bivalves to toxic dinoflagellates [PDF]

Invertebrate Survival Journal, 2012
Dinoflagellates and other microalgae can produce a wide spectrum of toxic molecules, which are the main responsible of shellfish poisoning syndromes. During seasonal harmful algal blooms (HABs), many filter-feeding marine invertebrates, including bivalve

Anti-Bacterial Adhesion Activity of Tropical Microalgae Extracts

Molecules, 2018
The evolution of regulations concerning biocidal products aimed towards an increased protection of the environment (e.g., EU Regulation No 528/2012) requires the development of new non-toxic anti-fouling (AF) systems.

Flow cytometric phytoplankton concentration and optical properties across instruments and laboratories

Limnology and Oceanography: Methods, EarlyView.
Abstract Flow cytometry measures the optical properties of individual cells and has become essential for enumerating and characterizing marine phytoplankton. Yet systematic comparison of measurements across instruments remains limited, hampering data comparison across laboratories and long‐term time series.

Comparison of particle properties and biovolume estimates from FlowCam and microscopy for kettle hole phytoplankton communities

Limnology and Oceanography: Methods, EarlyView.
Abstract The integration of high‐throughput image–based flow cytometry into routine phytoplankton assessment requires rigorous evaluation against established microscopy techniques. As method agreement is often site‐ and species‐specific, case‐by‐case validation is essential to successfully adopt emerging methods.
