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.

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

open access: yesIntegrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

Development and Reproduction of Nesidiocoris tenuis Reuter (Heteroptera: Miridae): The Effect of Temperature, Origin and Food

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Nymphal development took longer at 25°C than 30°C, and the Greek N. tenuis population developed more slowly than the commercial population. Nymphs clearly preferred E. kuehniella eggs over Artemia sp. cysts when both were offered equally. Egg production increased at 30°C, while female longevity declined.
