Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

Benthic Microalgae Respond More Strongly to Warming and Salinity Than Zooplankton. [PDF]

open access: yesEcol Evol
The effects of multiple simultaneous stressors on different trophic levels are poorly known. Warming changed the composition of both benthic diatom and zooplankton communities, but the interaction of warming and decreasing salinity affected only benthic diatoms. ABSTRACT The effects of elevated temperature are pronounced in high latitudes where warming

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

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

open access: yesEnvironmental 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.

Zooplankton Community Stability and Environmental Filtering in a Shallow Eutrophic Lake. [PDF]

open access: yesEcol Evol
Anthropogenic pressures led to zooplankton shift to small‐bodied dominance, not structural reorganization. Integrated management is crucial for long‐term resilience. ABSTRACT Zooplankton are key regulators of trophic interactions and nutrient cycling in shallow eutrophic lakes and are sensitive indicators of ecological responses to anthropogenic ...

Zooplankton fecal pellets as a vector transporting microplastics and associated toxins to the deep ocean

open access: yes, 2022
Toxins within the fecal pellets of zooplankton were measured along a transect from Hawaii to San Diego, passing through the southern edge of the Great Pacific Garbage Patch.

Nutrient enrichment destabilizes aquatic food webs through synchronization within and across trophic levels

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nutrient enrichment destabilizes ecosystems globally, but the mechanistic pathways underlying this effect in multi‐trophic communities remain unclear. To address this knowledge gap, we applied biodiversity–stability theory to multi‐trophic communities by partitioning ...

Capturing quantitative zooplankton information in the sea: Performance test of laser optical plankton counter and video plankton recorder in a Calanus finmarchicus dominated summer situation [PDF]

open access: yes, 2012
We compared two optical plankton counters, the Laser Optical Plankton Counter (LOPC) and the Video Plankton Recorder (VPR) for their abundance estimates of Calanus finmarchicus during an early summer situation (June 2008) in two North Norwegian fjords ...

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

open access: yesJournal 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.
