Influence of Age and Exposure Pathway on Copper and Cadmium Mixture Toxicity: A Study on Daphnia magna

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

The Effects of the Glutinicus Supplementation on Performance, Eggshell and Egg Yolk Color of Layers [PDF]

open access: yesJournal of Animal Science and Technology, 2004
An experiment was conducted to determine the effects of dietary supplementation of the yeast Rhodotorula glutinis(Glutinicus) on the performance and egg quality of layers. A total of 360 ISA Brown layers at 72 weeks old were assigned to one of the following 6 diets: control, 25 ppm β-carotene, 0.5%, 1%, 2% and 4% Glutinicus supplemented diets.

Increased energetic cost of movement reduces reproductive output in zebrafish at different temperatures and water flow rates

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Locomotion consumes a large proportion of individual energy budgets and may impose energetic constraints on other fitness‐related traits particularly under variable environmental conditions.

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.
