Transcriptome Analysis of Scrippsiella trochoidea CCMP 3099 Reveals Physiological Changes Related to Nitrate Depletion

Cooper, J. T., Sinclair, G. A., & Wawrik, B. (2016, May 9). Frontiers in Microbiology.

By: J. Cooper *, G. Sinclair n & B. Wawrik *

author keywords: transcriptome; Scrippsiella trochoidea; harmful algae; nutrient limitation; nitrogen; dinoflagellates; phytoplankton; algal physiology
topics (OpenAlex): Microbial Community Ecology and Physiology; Wastewater Treatment and Nitrogen Removal; Protist diversity and phylogeny
TL;DR: Surprisingly, the transcriptome also contained transcripts potentially related to secondary metabolite production, including a homolog to the Short Isoform Saxitoxin gene (sxtA) from Alexandrium fundyense, which was significantly up-regulated under N-depletion. (via Semantic Scholar)

2015 article

Deep-water seed populations for red tide blooms in the Gulf of Mexico

Waters, L. G., Wolcott, T. G., Kamykowski, D., & Sinclair, G. (2015, April 13). Marine Ecology Progress Series.

By: L. Waters  n, T. Wolcott n, D. Kamykowski n & G. Sinclair n

author keywords: Harmful algal blooms; Benthic orientation; Karenia brevis; Nutrient limitation; Biomimetic; Lagrangian drifter
topics (OpenAlex): Marine and coastal plant biology; Marine and coastal ecosystems; Coastal wetland ecosystem dynamics
TL;DR: Measurements of nutrients and light from the water column in a potential bloom- forming region of the WFS were higher than the model-generated requirements for growth, suggesting that coastal nutrient distributions could support a coastal population offshore. (via Semantic Scholar)

2009 article

LIPID CLASS, CAROTENOID, AND TOXIN DYNAMICS OF KARENIA BREVIS (DINOPHYCEAE) DURING DIEL VERTICAL MIGRATION1

Schaeffer, B. A., Kamykowski, D., McKay, L., Sinclair, G., & Milligan, E. (2009, February 1). Journal of Phycology.

By: B. Schaeffer n, D. Kamykowski n, L. McKay n, G. Sinclair n & E. Milligan n

author keywords: behavior; brevetoxins; dinoflagellate; epoxidation state; lipids
topics (OpenAlex): Photosynthetic Processes and Mechanisms; Biocrusts and Microbial Ecology; Algal biology and biofuel production
TL;DR: K. brevis may mobilize its toxins into the surrounding environment by reducing lipid concentrations, such as sterols, limiting competition, or toxins are released because lipids are decreased in high light, reducing any protective mechanism against their own toxins. (via Semantic Scholar)

2007 article

A COMPARISON OF PHOTORESPONSE AMONG TEN DIFFERENT KARENIA BREVIS (DINOPHYCEAE) ISOLATES1

Schaeffer, B. A., Kamykowski, D., McKay, L., Sinclair, G., & Milligan, E. J. (2007, July 30). Journal of Phycology.

By: B. Schaeffer n, D. Kamykowski n, L. McKay n, G. Sinclair n & E. Milligan n

author keywords: carbon; cell division rate; culture; dinoflagellate; F-v/F-m; Karenia brevis; P-E curve; photoinhibition
topics (OpenAlex): Marine and coastal ecosystems; Marine Toxins and Detection Methods; Isotope Analysis in Ecology
TL;DR: PAM‐FL techniques used to investigate P–E curves, quantum yield of PSII (Fv/Fm), and chl from 10 K showed that K. brevis was more than capable of utilizing and surviving in light conditions that may be present on cloudless days off Florida. (via Semantic Scholar)

Comparison of swimming speed and photophysiological responses to different external conditions among three Karenia brevis strains

McKay, L., Kamykowski, D., Milligan, E., Schaeffer, B., & Sinclair, G. (2006, February 11). Harmful Algae.

By: L. McKay  n, D. Kamykowski n, E. Milligan n, B. Schaeffer n & G. Sinclair n

author keywords: behavior; dinoflagellate; intraspecies comparison; Karenia brevis
topics (OpenAlex): Marine and coastal ecosystems; Aquatic Ecosystems and Phytoplankton Dynamics; Microbial Community Ecology and Physiology
TL;DR: The results suggest that cells may partition energy selectively depending on the needs of the cell, and a generalized species response to light and temperature ranges. (via Semantic Scholar)

Nitrate uptake by Karenia brevis. I. Influences of prior environmental exposure and biochemical state on diel uptake of nitrate

Sinclair, G. A., Kamykowski, D., Milligan, E., & Schaeffer, B. (2006, December 20). Marine Ecology Progress Series.

By: G. Sinclair n, D. Kamykowski n, E. Milligan n & B. Schaeffer n

author keywords: Karenia brevis; dinoflagellate; physiology; nocturnal uptake; vertical migration
topics (OpenAlex): Marine and coastal ecosystems; Microbial Community Ecology and Physiology; Aquatic Ecosystems and Phytoplankton Dynamics
TL;DR: Testing how the physiology of K. brevis contributed to the acquisition of nitrate by evaluating how nitrate uptake changed with prior environmental exposure found enhanced nocturnal uptake compared to cells continuously exposed to nitrate-replete conditions. (via Semantic Scholar)

Nitrate uptake by Karenia brevis. II. Behavior and uptake physiology in a nitrate-depleted mesocosm with a bottom nutrient source

Sinclair, G. A., Kamykowski, D., Milligan, E., & Schaeffer, B. (2006, December 20). Marine Ecology Progress Series.

By: G. Sinclair n, D. Kamykowski n, E. Milligan n & B. Schaeffer n

author keywords: Karenia brevis; dinoflagellate; physiology; nocturnal uptake; vertical migration; sediment
topics (OpenAlex): Marine and coastal ecosystems; Aquatic Ecosystems and Phytoplankton Dynamics; Microbial Community Ecology and Physiology
TL;DR: Both migration, as indicated by diel aggregation patterns, and cell physiology indicate that descent to regions of higher nutrient concentrations were sufficient to main- tain average growth rates of 0.3 div d -1 . (via Semantic Scholar)
