Diguanosinetetraphosphate guanylohydrolase in Artemia salina
1. The diguanosinetetraphosphate guanylohydrolase (EC 3.6.1.17) of Artemia salina has been found to be located in the cytosol while its substrate, diguanosine tetraphosphate, is in the sediment. 2. Two spectrophotometric methods have been developed to study this enzyme.

ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...

An integral part of the technological preparation of artificial cultivation of brine shrimp in saline water is a set of preliminary experimental work to assess the quality of cysts. It has been shown that during the winter period, activation of Artemia cysts occurs from the initial hatching values of 5-10 % to 72-99 %.

Mitochondrial function predicts dominance status in brown trout
Read the free Plain Language Summary for this article on the Journal blog. Abstract In social hierarchies, winning contests confers better access to food, shelter and reproductive opportunities. Clear dominance relationships are often apparent even when opponents are matched for experience, age, size and other obvious characteristics.

Developmental environment and age shape macronutrient allocation to eggs and ejaculates
Read the free Plain Language Summary for this article on the Journal blog. Abstract Environmental conditions during development can have lasting effects on reproductive investment, but the sex‐ and age‐specific nature of such effects remains poorly understood.

Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

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 ...
