Cyclonic Mesoscale Eddy Impact on Zooplankton Vertical Migration at Station ALOHA in the Coast of Hawaii

open access: yes, 2021
Light intensity over the course of a day sets the circadian rhythm for the vertical movement of microorganisms across the entire ocean. This research focused on the distribution of zooplankton at station ALOHA off the coast of Hawaii and examines the ...

Is DNA metabarcoding an option for formaldehyde‐preserved zooplankton time series?

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The recovery of amplifiable DNA from formaldehyde‐fixed (FF) zooplankton samples has long been considered problematic, but advances in degraded‐DNA retrieval have renewed interest in FF samples. To access the information stored in long‐term zooplankton time series, we evaluated methods for extracting amplifiable DNA from community samples ...

Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

Defining the “to” in end-to-end models [PDF]

open access: yes, 2009
Robust models relating climate change to fish production require an adequate description of planktonic intermediaries between phytoplankton and fish in end-to-end models.

Automatization of multistep sample preparation for microplastics monitoring in aquatic environments

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Microplastics (MP) have been found in every environmental compartment in urban and remote areas. Although their ubiquity is widely recognized, the lack of harmonized protocols for sampling, sample preparation, and particle identification/quantification hinders comparability among studies.

Zooplankton response to organic carbon level in lakes of differing trophic states

open access: yesKnowledge and Management of Aquatic Ecosystems, 2014
Water eutrophication is associated with an increase in the organic carbon content (both particulate and dissolved forms), which may affect the functioning of the zooplankton community.

The consumption of zooplankton by early life stages of fish in the North Sea [PDF]

open access: yes, 2007
Previous work has shown that during the 1970s, fish and carnivorous macrozooplankton together consumed ~22 gC m-2 year-1 of mesozooplankton, principally copepods.

Drivers of stability in plankton communities: dominance, asynchrony, and averaging effects across temporal, spatial and trophic scales

open access: yesOikos, EarlyView.
The origins of ecosystem stability have long intrigued ecologists. Recent theoretical advancements highlight three primary mechanisms driving stability: dominance, asynchrony and averaging. While plant community stability has been extensively studied, our understanding of marine community stability remains limited. Plankton, as key components of marine

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 ...
