In environments where food resources are spatially variable and temporarily impoverished, consumers that encounter habitat patches with different food density should focus their foraging initially where food density is highest before they move to patches where food density is lower.Increasing missed opportunity costs should drive individuals progre
The decline in the eastern North American population of the monarch butterfly population since the late 1990s has been attributed to the loss of milkweed during the summer breeding season and the consequent reduction in the size of the spidertattooz.com summer population that migrates to central Mexico to overwinter (milkweed limitation hypothesis)
In ITER, the helium (He) impurity produced by the deuterium-tritium reaction will bombard the tungsten (W) divertor armor at the strike points.Consequently, strong interaction occurs therein that both impact the performance of the plasmas and the lifetime of the divertor.Despite an ever-increasing understanding of this interaction, some experimenta
In cystic fibrosis (CF), defective biogenesis and activity of the cystic fibrosis transmembrane conductance regulator (CFTR) leads to airway dehydration and impaired mucociliary clearance, resulting in chronic airway infection and inflammation.The most common CFTR mutation, F508del, results in a processing defect in which the protein is retained sp
