Statistical filtering to aid in the sorting of phytoplankton: The effects of image library size and phytoplankton shape

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The demand for efficient image sorting methods has increased due to technological advancements that enable more intensive phytoplankton monitoring. Both statistical and machine learning algorithms can misidentify algal taxa in taxonomically diverse samples, in which phytoplankton morphology and image traits can vary.

How The Environmental RNA Signature of Nitrate Reductase Can Be Used as a Predictor for Phytoplankton Distribution [PDF]

open access: yes, 2021
With anthropogenic climate change altering the ocean, it is critical to understand what variables control phytoplankton distribution so we can predict how distributions will be altered as result of climate change.

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

open access: yesMarine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

IDENTIFICATION OF RELEVANT TIME-SCALES IN NONEQUILIBRIUM COMMUNITY DYNAMICS - CONCLUSIONS FROM PHYTOPLANKTON SURVEYS [PDF]

open access: yes, 1994
This paper is a reflection on J.B. Wilson's (1990) publication which presents an attempt to understand the development of terrestrial plant communities of New Zealand against twelve different explanations of Hutchinson's Paradox.

Temperature orchestrates phytoplankton community and environment in mountain stream for enhancing resource use efficiency

open access: yesFrontiers in Marine Science
Warming is a key factor influencing the function of the structure and function of phytoplankton communities. However, the impacts of temperature on phytoplankton resource use efficiency (RUE) in mountain rivers remain poorly understood.

Effects of preservatives and poisons on the elemental and isotopic composition of freshwater particulate organic matter

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Sediment traps, often used in tandem with preservatives or poisons, are widely used for the collection of particulate organic matter (POM), providing insight into the source to sink mechanisms that shape major biogeochemical cycles and sedimentary carbon sequestration.
