Attitude, Perception and Judgment changes in cope with very cold weather conditions: a qualitative study
Significant psychological changes in extremely cold regions are considered as natural human reactions. Antarctica has very cold conditions and is considered a natural laboratory for many studies in various fields. Survival, in this harsh environment, is unmanageable without human preconditions; Antarctica with a focus on resilience and psychological adjustment, an opportunity for the individual...
متن کاملSucrose helps regulate cold acclimation of Arabidopsis thaliana
A test was carried out to see if sucrose could regulate cold-acclimation-associated gene expression in Arabidopsis. In plants and excised leaves, sucrose caused an increase in GUS activity, as a reporter for the activity of the cold-responsive COR78 promoter. This increase was transient at 21 degrees C but lasted for at least 4 d at 4 degrees C in continuous darkness. However, at 4 degrees C wi...
متن کاملEvolution of mammals: lactation helps mothers to cope with unreliable food supplies.
Lactation is a ubiquitous feature of mammalian reproduction. Because lactating females can draw on their nutrient reserves for milk production, it offers mothers and their dependent young independence from fluctuations in their food supplies. However, converting food to reserves and milk is relatively inefficient at delivering nutrients to offspring. We use dynamic programming to contrast the p...
متن کاملEffects of cold narcosis on memory acquisition, consolidation and retrieval in honeybees (Apis mellifera).
In learning and memory studies on honeybees (Apis mellifera), cold-induced narcosis has been widely used to temporarily immobilize honeybees. In this study, we investigated the effects of cold narcosis on the associative memories in honeybees by using the proboscis extension response (PER) paradigm. Severe impairments in memory acquisition was found when cold narcosis was performed 30 min, inst...
متن کاملIntermodal blocking in honeybees.
Previous findings of intramodal but not of intermodal blocking in foraging honeybees prompted a new series of experiments with colours, odours, a proximal visual landmark, and a localized geomagnetic anomaly as stimuli. In Experiments 1-2, the landmark was blocked by both colour and odour. In Experiments 3-6, the anomaly was blocked by both colour and odour, but the anomaly failed to block eith...
