Multitrophic alpha and beta diversity of lake plankton across Canada

Oikos, EarlyView.
Anthropogenic environmental changes impact freshwater biodiversity globally. While biodiversity assessments in freshwater environments have traditionally focused on individual groups of organisms or trophic levels, considering patterns of ‘multitrophic biodiversity' across the food web provides a more comprehensive view of anthropogenic impacts and ...

The contribution of differential hatching success to the fitness of species and interspecific hybrids [PDF]

, 2007
Resting egg banks of microcrustaceans have been used to reconstruct the evolutionary and ecological history of species. However, recent studies provided evidence for a discrepancy between dormant propagules in the sediment and the planktonic population ...

Ciliated Epibionts Modify the Cardiac Stress Reaction to Perceived Predation in Daphnia

Microorganisms
When animals perceive an acute stressor like a predator, they typically undergo a suite of physiological changes that function to improve survival during the encounter, such as elevation in cardiac output, to supply more energy to muscles.

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

Environmental 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—

Diet quality determines interspecific parasite interactions in host populations [PDF]

, 2014
The widespread occurrence of multiple infections and the often vast range of nutritional resources for their hosts allow that interspecific parasite interactions in natural host populations might be determined by host diet quality. Nevertheless, the role

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

Environmental Toxicology, EarlyView.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...
