Functional Identity Drives Directional Shifts in Freshwater Plankton Biomass-Size Relationships. [PDF]

Ecol Lett
Normalized biomass size spectra (NBSS) for four plankton functional groups across 588 Canadian lakes. Colours correspond to each functional group; points represent the mean normalized biomass for each size bin aggregated across all lakes, ranging from 0.1 to 3.5 μm.

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

Marine 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 ...

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

Marine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

Zooplankton Structure and Potential Food Web Interactions in the Plankton of a Subtropical Chain-of-Lakes

The Scientific World Journal, 2002
This study evaluates the taxonomic and size structure of macro-zooplankton and its potential role in controlling phytoplankton in the Kissimmee Chain-of-Lakes, six shallow interconnected lakes in Florida, U.S.

Long-term dynamics of forage base and food supply for nekton in the upper epipelagic layer of the western Bering Sea. Part 1. Composition and abundance of zooplankton and small-sized nekton

Известия ТИНРО, 2022
An updated concept for the state, dynamics, and production of plankton communities in the upper epipelagic layer of the western Bering Sea is presented based on the timeseries for 1986–2020.

Ecological optimization of biomass and lipid production by microalgae [PDF]

, 2012
Microalgae have higher growth rates and higher lipid content than terrestrial plants and the yield per unit area is even higher by several orders of magnitude.

Diel vertical migration of Arctic zooplankton during the polar night [PDF]

, 2009
High-latitude environments show extreme seasonal variation in physical and biological variables. The classic paradigm of Arctic marine ecosystems holds that most biological processes slow down or cease during the polar night.

Influence of environmental factors on the formation of zooplankton communities in a large lake system in Uzbekistan [PDF]

E3S Web of Conferences, 2023
Currently, the Aidar-Arnasai Lake System (AALS) is of great environmental and commercial importance for Uzbekistan. The article discusses the influence of mineralisation, temperature and diversity of biotopes on the change in the species composition in ...

Short-term fish predation destroys resilience of zooplankton communities and prevents recovery of phytoplankton control by zooplankton grazing.

PLoS ONE, 2019
Planktivorous fish predation directly affects zooplankton biomass, community and size structure, and may indirectly induce a trophic cascade to phytoplankton.
