Nutrient and carbonate chemistry patterns associated with Karenia brevis blooms in three West Florida Shelf estuaries 2020-2023

Frontiers in Marine Science
Ocean acidification (OA) driven by eutrophication, riverine discharge, and other threats from local population growth that affect the inorganic carbonate system is already affecting the eastern Gulf of Mexico.

An effective algaecide for the targeted destruction of Karenia brevis

Harmful Algae
We address the targeted destruction of Karenia brevis using the algaecide calcium peroxide, in tandem with the flocculation and sinking of the species. The specific aspect of the approach is the incorporation of the algaecide within the floc to rapidly kill K. brevis, thus minimizing escape of cells from the floc and reentry to the water column.

Warming effects on marine microzooplankton and mixoplankton: Physiological responses, community reorganization, and implications for a warming ocean

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Microzooplankton and mixoplankton are key regulators of marine food webs, yet their responses to ocean warming and thermal extremes remain incompletely integrated across physiological, community, and ecosystem scales. This synthesis examines how temperature shapes the physiology, trophic strategies, and community dynamics of these protistan ...

Phylogeny‐based generic delimitations of the diverse leafhopper tribe Gyponini, including the establishment of a new tribe of Iassinae (Hemiptera: Cicadellidae)

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
Phylogenetic relationships among 97.6% of Gyponini genera and 97.4% of subgenera were inferred using morphological and multilocus molecular data. Analyses support the monophyly of Gyponini, transfer Hoplojassini to Hylicinae and establish Chilenanini trib. nov. within Iassinae.

Comparative analysis of three brevetoxin-associated bottlenose dolphin (Tursiops truncatus) mortality events in the Florida Panhandle region (USA).

PLoS ONE, 2012
In the Florida Panhandle region, bottlenose dolphins (Tursiops truncatus) have been highly susceptible to large-scale unusual mortality events (UMEs) that may have been the result of exposure to blooms of the dinoflagellate Karenia brevis and its ...

The degradation of Karenia brevis toxins utilizing ozonated seawater

Harmful Algae, 2003
Abstract Florida red tides impose both an economic and health impact on the state. The purpose of this research was to examine the effectiveness of ozone to reduce the numbers of Florida red tide organism ( Karenia brevis Davis) and its associated toxins in an artificial seawater environment.

Fusing Multi‐ and Hyperspectral Satellite Data for Harmful Algal Bloom Monitoring With Self‐Supervised and Hierarchical Deep Learning

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract We present a self‐supervised machine learning framework for detecting and mapping the severity and speciation of harmful algal blooms (HABs) using multi‐sensor satellite data. By fusing reflectance data from operational polar‐orbiting satellite‐based instruments (VIIRS, MODIS, OLCI, and OCI) with TROPOMI solar‐induced fluorescence (SIF), our ...

Chimeric Plastid Proteome in the Florida “Red Tide” Dinoflagellate Karenia brevis

Molecular Biology and Evolution, 2006
Current understanding of the plastid proteome comes almost exclusively from studies of plants and red algae. The proteome in these taxa has a relatively simple origin via integration of proteins from a single cyanobacterial primary endosymbiont and the host.

Chronic and punctuated changes in subtropical reef fish assemblages

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Understanding temporal changes in marine biodiversity is crucial for managing and conserving reef ecosystems in the face of global environmental shifts. Although biodiversity changes at global and regional scales often differ, the role of subtropical systems in these patterns has been relatively understudied until recently.
