Comparing the Effects of Microplastics From Conventional Cigarette Butts and Heated Tobacco Device: The Role of UV‐Induced Aging

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Despite the widespread presence of cigarette butts in the environment, the potential toxicological effects posed by microplastics (MPs) derived from them remain poorly understood. In this study, we compared the effects of MPs from conventional cigarette butts (cellulose acetate) and heated tobacco devices (cellulose acetate and polylactic acid

Terrestrial Isopods as Biotic Generators of Microplastics Following Chronic Exposure to Weathered Low‐Density Polyethylene

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Terrestrial detritivores such as isopods and springtails play a vital role in cycling nutrients through soil ecosystems. Microplastics (MPs, < 5 mm) are increasingly recognized as contaminants of terrestrial soils, yet little is known about whether soil invertebrates themselves are impacted by consuming these plastics or if they can generate ...

Temperature-dependent effect of filamentous cyanobacteria on Daphnia magna life history traits

open access: yesJournal of Limnology, 2011
Filamentous cyanobacteria are unsuitable food for Daphnia due to their poor manageability, poor nutritional value and, in some cases, toxicity. As the strength of harmful effects of cyanobacteria on filter-feeding zooplankton is temperature dependent ...

Multiscale Effects of Environmentally Relevant Mixtures Containing Two Estrogenic Endocrine Disruptors, Chlordecone and Propylparaben, in Hydra vulgaris Pallas, 1766

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study investigates the chronic effects of chlordecone (CLD) and propylparaben (PP), two pro‐estrogenic endocrine disruptors, on Hydra vulgaris Pallas, 1766 using a multiscale approach over a 14‐day exposure period. Environmentally relevant concentrations of CLD (0.5, 5, 20 μg L−1) and PP (0.01, 0.05, 0.40 μg L−1) were tested individually ...

The ‘big houses‐big cars dilemma’: How do we reconcile the prevalence of positive correlations among life history traits?

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Life history theory assumes that there are negative correlations among different components of the life history—investing more in reproduction now means taking resources away from growth, maintenance or the ability to reproduce in the future.

Daphnia body size and population dynamics under predation by invertebrate and fish predators in Lago Maggiore: an approach based on contribution analysis

open access: yesJournal of Limnology, 2008
Predation on Daphnia is size-specific: while zooplanktivorous fish select large, ovigerous females, carrying larger clutches, predation by invertebrates, particularly Cladocera, is generally regarded as acting mainly on young, small, non-ovigerous ...
