Plankton are not passive tracers: Plankton in a turbulent environment [PDF]

open access: yesJournal of Geophysical Research: Oceans, 2006
Spectral analysis was performed on a series of oceanographic transects collected using an optical plankton counter and conductivity‐temperature‐depth probe. The “physical” time series (i.e., temperature) power spectra showed a single passive scaling relationship across the entire range of sampling scales (1–8192 s) that was expected from turbulence ...

Genomic evidence for global ocean plankton biogeography shaped by large-scale current systems

open access: yesbioRxiv, 2019
Biogeographical studies have traditionally focused on readily visible organisms, but recent technological advances are enabling analyses of the large-scale distribution of microscopic organisms, whose biogeographical patterns have long been debated1,2 ...

Deep Learning Classification of Lake Zooplankton

open access: yesFrontiers in Microbiology, 2021
Plankton are effective indicators of environmental change and ecosystem health in freshwater habitats, but collection of plankton data using manual microscopic methods is extremely labor-intensive and expensive.

The Effects of Alewife on the Zooplankton Community in Townhouse Pond [PDF]

open access: yes, 2009
The purpose of this study was to determine what plankton species was more dominant in Townhouse Pond and what effects predation has on the food web. Plankton size is important when determining pelagic food web structure.

[Corrigendum to] Effects of small-scale turbulence on lower trophic levels under different nutrient conditions [vol 32, pg 197, 2010] [PDF]

open access: yes, 2009
Small-scale turbulence affects the pelagic food web and energy flow in marine systems and the impact is related to nutrient conditions and the assemblage of organisms present.

Current practice in plankton metabarcoding: optimization and error management

open access: yesJournal of Plankton Research, 2019
High-throughput sequencing of a targeted genetic marker is being widely used to analyze biodiversity across taxa and environments. Amid a multitude of exciting findings, scientists have also identified and addressed technical and biological limitations ...

Community‐Level Responses to Iron Availability in Open Ocean Plankton Ecosystems

open access: yesGlobal Biogeochemical Cycles, 2019
Predicting responses of plankton to variations in essential nutrients is hampered by limited in situ measurements, a poor understanding of community composition, and the lack of reference gene catalogs for key taxa.

Fifty years of limnological data on Lake Stechlin, a temperate clearwater lake

open access: yesScientific Data
We present 50 years of monitoring data on water quality of Lake Stechlin, a deep, dimictic hardwater lake in northeastern Germany known for its exceptionally clear water.

Some aspects of the ecology of the limnoplankton, with special reference to the phytoplankton. [Translation from: Svensk Botanisk Tidskrift 13(2) 129-163, 1919.] [PDF]

open access: yes, 1919
This paper tries to develop more generally some fundamental bases for the ecological study of freshwater plankton. A special attention is given to the phytoplankton associations which can be separated out and made into groups according to their ...

Combined effects of a parasite, QPX, and the harmful-alga, Prorocentrum minimum on northern quahogs, Mercenaria mercenaria [PDF]

open access: yes, 2010
Northern quahogs, Mercenaria mercenaria (L.), frequently are infected with the parasite Quahog Parasite Unknown (QPX, Labyrintohomorpha, Thraustochytriales), which can cause morbidity and mortality of the quahogs.
