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 ...

Effect of suspended solids on interaction between filter-feeding fish Aristichthys nobilis and zooplankton in a shallow lake using a mesocosm experiment

Journal of Freshwater Ecology, 2017
Suspended solids (SS) resulting from sediment resuspension (SR) can impact ecosystems through direct and indirect effects on freshwater organisms and their interactions.

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.

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 ...

Resource Availability Modulates Effects of Fluorine Free Firefighting Foams

Environmental Toxicology, EarlyView.
ABSTRACT Fluorine‐free foam (F3) alternatives that lack per‐ and polyfluoroalkyl substances (PFAS) are rapidly being adopted for firefighting operations and will be entering ecosystems. Despite this, little is known about their impact on freshwater communities.

Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

Environmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

Statistical Mechanics of Zooplankton

PLOS ONE, 2015
Statistical mechanics provides the link between microscopic properties of many-particle systems and macroscopic properties such as pressure and temperature. Observations of similar "microscopic" quantities exist for the motion of zooplankton, as well as many species of other social animals.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Impact of seasonal changes in zooplankton biodiversity in Ukkadam Lake, Coimbatore, Tamil Nadu, India, and potential future implications of climate change

Journal of Basic and Applied Zoology, 2018
Background Zooplankton biodiversity serves as an ecological indicator of aquatic environment due to their rapid response according to environmental changes. At the present study, impact of seasonal changes on zooplankton biodiversity was conducted in the

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...
