Salinity-induced chemical, mechanical, and behavioral changes in marine microalgae

چکیده
Abstract This study examines how salinity reduction triggers the response of three marine microalgae at molecular and unicellular levels in terms chemical, mechanical, behavioral changes. At lowest salinity, all microalgal species exhibited an increase membrane sterols behaved stiffer. The glycocalyx-coated Dunaliella tertiolecta was surrounded by a thick actin layer showed highest physiological activity, negatively affecting cell motility indicating formation palmella stage. lipid content hydrophobicity were largely preserved over wide range confirming euryhaline nature . with calcite-encrusted theca Tetraselmis suecica cells examined. 19, T. growth, flagellar detachment speed, activity associated dense network extracellular polymeric substances, decrease lipids, which could indicate develepment cyst organosilicate encrusted Cylindrotheca closterium appeared to be tolerant. It hydrophobically lower whereas becoming hydrophilic higher might related change released biopolymers. highlighted interplay between chemistry mechanics that determines functional behavior shows surface properties serve as stress markers for biota under climate change.

The effect of lamotrigin on stress-induced behavioral and biochemical changes in mice
Stress may cause special behavioral and biochemical changes. Kindling is presumed to be the underlying mechanism for such changes. Lamotrigin, an anti-kindling agent which blocks glutamate release through inhibiting sodium channels may reverse these behavioral changes. The aim of this study was to explore the effects of lamotrigin in management of behavioral and biochemical changes caused by st...

متن کاملSpearfishing-induced behavioral changes of an unharvested species inside and outside a marine protected area
By prohibiting fishing, marine protected areas (MPAs) provide a refuge for harvested species. Humans are often perceived as predators by prey and therefore respond fearfully to humans. Thus, fish responses to humans inside and outside of an MPA can provide insights into their perception of humans as a predatory threat. Previous studies have found differences in the distance that harvested speci...
متن کاملCadmium-induced behavioral changes in growing rats.
Sixty growing male albino rats of the ITRC bred colony, weighing 150-160 g (2 months old) , served as subjects. They were housed in stainless steel cages, in groups of ten and maintained on a 12:12 photoperiod (lights on 06.00-18.00 hr) in a temperature controlled (22 •} 2.0•‹) room. Hind Lever Laboratory chow and water were provided ad lib. The animals were divided into two equal groups and th...
