Trace Elements and Temperature Combined to Regulate Zooplankton Community Structures in Mountain Streams

Biology
Zooplankton, as an important component of mountain river ecosystems, play a crucial role in the cycling of matter and the flow of energy. However, the depth and systematic research on the formation mechanisms and influencing factors of zooplankton ...

Dietary partitioning mediates species coexistence in the high seas area of northwest Pacific

Ecography, EarlyView.
Niche partitioning, manifesting along various axes of the ecological niche, is a fundamental mechanism mediating species coexistence in a system. However, the emergence of many species in marine ecosystems would face considerable constraints in achieving coexistence through spatiotemporal differentiation mechanisms under the framework of niche ...

Dynamics of zooplankton production parameters in the north-western Bering Sea in the present period

Известия ТИНРО, 2016
On the basis of plankton surveys, conducted in the north-western Bering Sea in 2010-2015, the production characteristics of zooplankton were calculated and analyzed.

The relative importance of regional and local factors in shaping zooplankton diversity in high-altitude tropical shallow lakes

Journal of Freshwater Ecology, 2020
In Brazil, although, high-altitude shallow lakes comprise large parts of conservation units and are considered highly important environments for biodiversity studies, little is known about the factors that regulate the zooplankton community.

Continental scale metagenomics reveals Microcystis‐induced synchrony among aquatic taxa is exacerbated by trophic cascades

Ecography, EarlyView.
Harmful Microcystis proliferation severely threatens aquatic ecosystems globally, but its impacts on food‐web stability remain poorly understood. Here, we analyzed 1309 metagenomic samples from freshwater ecosystems across China to investigate how Microcystis abundance affects synchrony among taxa in multi‐trophic food webs (from bacteriophages to ...

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.

Zooplankton Biomass in Ponds - Determination of Biovolume and Dry Weight

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2023
The aim of this study was to evaluate the possibility of using simple screening methods to determine zooplankton biomass in ponds. Among the applicable methods, we selected sedimentation determination of wet biomass and dry biomass determination.

Synergistic mechanisms foster declines in native fish community stability following the introduction of non‐native species

Ecography, EarlyView.
Non‐native species introductions profoundly alter freshwater communities, yet the mechanisms by which non‐native fishes affect native community stability remain unclear. Using a multi‐decadal dataset on fish community composition and abundance collected across France, we quantified native community stability and decomposed this metric into its main ...

The nutritional status of zooplankton in a tropical reservoir: effects of food quality and community structure

Brazilian Journal of Biology
The temporal variability of energetic reserves of zooplankton in the eutrophic Pampulha reservoir was investigated during two successive annual cycles. The effects of dominance of large filter-feeding cladocerans (Daphnia) and the occurrence of massive ...

Crustacean zooplankton dynamics in a natural riverine lake, Upper Mississippi River

Journal of Freshwater Ecology, 2017
Zooplankton communities in riverine systems are typically thought to be driven by abiotic forces. However, recent studies have shown that biological controls are capable of structuring these communities in large rivers and may become more influential as ...
