Comparison between fluorometry and microscopy‐based phytoplankton assessments in the Laurentian Great Lakes

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Photosynthetic pigment fluorescence is commonly used in limnology and oceanography as a proxy for phytoplankton biomass. Fluorometry has been used to detect subsurface algal blooms, characterize dynamics of the deep chlorophyll layer, and to provide greater vertical resolution to phytoplankton monitoring.

Collaborative Sampling and Imaging of Phytoplankton Communities by Two Long‐Range Autonomous Underwater Vehicles Using Acoustic Tracking and Messaging

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.

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

open access: yesInvertebrate 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

open access: yesMolecules, 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.

Climate change promotes parasitism in a coral symbiosis. [PDF]

open access: yes, 2018
Coastal oceans are increasingly eutrophic, warm and acidic through the addition of anthropogenic nitrogen and carbon, respectively. Among the most sensitive taxa to these changes are scleractinian corals, which engineer the most biodiverse ecosystems on ...

Plate tectonics in the microscopy realm: Molecular insights into morphological variability of Peridinium willei (Peridiniales, Dinophyceae)

open access: yesTAXON, EarlyView.
Abstract Freshwater Peridinium willei (Peridiniaceae) is globally distributed, but reports linking its morphologies with DNA sequence data remain scarce. The taxonomy of the species, and its infraspecific taxa, remain ambiguous due to the lack of DNA sequence data for the original and type material.

Interaction patterns and assembly mechanisms of dinoflagellates and diatoms in a coastal bay suffering from long-term eutrophication

open access: yesmSphere
Dinoflagellates and diatoms are highly prevalent and ecologically important phytoplankton in coastal waters, greatly contributing to primary productivity in marine ecosystems.

Shoreline and deglaciation chronology in southeast Norway

open access: yesBoreas, EarlyView.
The postglacial relative sea level history is reconstructed in four areas of mid‐ and inner Oslofjorden in southeast Norway. The reconstructions are based on radiocarbon‐dated raised shoreline levels from 42 sites, mainly isolation basins, and limiting ages from four lakes above the marine limit.

Metatranscriptome Profiling Indicates Size-Dependent Differentiation in Plastic and Conserved Community Traits and Functional Diversification in Dinoflagellate Communities

open access: yesFrontiers in Marine Science, 2018
Communities of microscopic dinoflagellates are omnipresent in aquatic ecosystems. Consequently, their traits drive community processes with profound effects on global biogeochemistry.

Comparison of the Functional and Numerical Responses of Resistant versus Non-resistant Populations of the Copepod Acartia Hudsonica Fed the Toxic Dinoflagellate Alexandrium Tamarense [PDF]

open access: yes, 2007
The functional and numerical responses of grazers are key pieces of information in predicting and modeling predator–prey interactions. It has been demonstrated that exposure to toxic algae can lead to evolved resistance in grazer populations.
