Multi‐Tool Marine Metabarcoding Bioassessment for Baselining and Monitoring Species and Communities in Kelp Habitats

Molecular Ecology Resources, EarlyView.
ABSTRACT The astonishing biological diversity found in Californian kelp forests requires efficient and robust monitoring tools to better understand ecological trends and mitigate against loss or disruption of ecosystem services due to human pressure and climate changes.

Energy Flows in the Vistula Lagoon of the Baltic Sea [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2012
Energies of the Vistula Lagoon ecosystem is estimated based on observations made by authors in the northern Vistula Lagoon literature data. The pelagic and bottom communities are represented by euryhaline species: phytoplankton - 412, zooplankton - 74 ...

The evolution of reproduction in Ediacaran–Cambrian metazoans

Biological Reviews, EarlyView.
ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

Evaluation of Bega River Water Quality Using Biotic Indices

Scientific Papers Animal Science and Biotechnologies, 2023
The main purpose of the topic is to research ecological indices resulting from the analysis of zoo-benthos communities in order to use them combined as a method of diagnosing the water quality of the Bega River in the area of Timisoara.

The role of structuring benthos for juvenile flatfish [PDF]

Journal of Sea Research, 2013
article i nfo Within coastal nurseries, the distribution of juvenile flatfish may depend on small-scale habitat variability. The presence of ecosystem engineers is known to have important impacts in coastal sediments. Lanice conchilega is a well-known marine ecosystem engineer of shallow soft bottom ecosystems, shaping the macrobenthic community and ...

Large‐scale depth‐related seasonal distribution patterns of a benthic‐feeding sea duck in two contrasting marine systems

Ibis, EarlyView.
Moulting and overwintering Common Scoter Melanitta nigra aggregate in largely undisturbed, shallow‐water marine areas, preying upon sessile benthic organisms (mainly bivalves), which do not reproduce during this period of exploitation. Assuming even prey distribution, we predict that Common Scoters would aggregate to moult in shallowest waters with ...

Influence of Trophic Relations in the Shelf Communities on Benthos: Trophic Structure and the Effects of Grazing Pressure [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2013
Influence of the plankton and nekton on the benthos, which form total shelf community is considered. Trophic structure of benthos of different parts of the World Ocean shelves has been reviewed and made its classification.

Biotic Mechanisms Strengthen Functional and Phylogenetic Convergence of Reef Fish Assemblages at Higher Latitudes

Journal of Biogeography, EarlyView.
ABSTRACT Aim How communities of organisms come together has long fascinated scientists, with renewed interest in using functional and evolutionary patterns to infer mechanisms of community assembly. Ecological theory predicts that biotic interactions could lead to either divergence in the event of niche partitioning or convergence through the exclusion

The biological pump effects of phytoplankton on the occurrence and benthic bioaccumulation of hydrophobic organic contaminants (HOCs) in a hypereutrophic lake

Ecotoxicology and Environmental Safety, 2021
The distribution of hydrophobic organic contaminants (HOCs) in eutrophic ecosystems has been widely studied, but how phytoplankton blooms affect their occurrence and benthic bioaccumulation is poorly understood. To fill this knowledge gap, the biological

A very picky eater: Species‐level prey selection in the endangered Rhone streber [Zingel asper (L. 1758)]

Journal of Fish Biology, EarlyView.
Abstract Prey preferences are important drivers of predator–prey interactions and trophic network structure. We present a species‐level selection analysis for the endangered Zingel asper (L. 1758) and its prey within the Baetis (Ephemeroptera) genus.
