Integrative 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 ...

Acta Zoologica, EarlyView.ABSTRACT The study of genes involved in sexual differentiation, as Vasa and Sox9, is of great importance, as they serve as specific markers for the germline and the male differentiation pathway, respectively. This study characterized using immunofluorescence the expression of the Vasa and Sox9 genes and laminin during gonadal differentiation in larvae ...

Journal of the Marine Biological Association of the United Kingdom, 2006 Field surveys were conducted in order to collect information on the occurrence of wild Artemia populations in hypersaline environments such as salt lakes, lagoons and salty rivers. The mating behaviour of Artemia populations and the presence or absence of males were carefully recorded. Sampling involved the use of plankton nets.

The Effect of Familiarity Among Social Partners on the Jumping Behavior of Amazon Mollies
Ethology, EarlyView.Pairs of familiar or nonfamiliar clonal Amazon mollies were tested in individual bowls, from which they could only escape from by jumping. Familiar pairs remained together significantly more than non‐familiar ones. Other behavioral aspects, such as timing and direction of jumps was not affected by familiarity.

Impact of β-Carotene Enrichment on Carotenoid Composition and Gene Expression in Artemia Metanauplii [PDF]
Background: Carotenoids play essential nutritional and physiological roles in aquatic animals. Since aquatic species cannot synthesize carotenoids de novo, they must obtain these compounds from their diet to meet the physiological and adaptive ...

Journal of Applied Entomology, EarlyView.ABSTRACT The use of alternative food has become an integral component of biocontrol, allowing the introduction and establishment of predators into a crop before pest invasion and sustaining populations even when pest densities are low. The addition of alternative food also has a positive long‐term effect in decreasing the densities of the pest.
