Does allopreening control avian ectoparasites?
For birds, the first line of defence against ectoparasites is preening. The effectiveness of self-preening for ectoparasite control is well known. By contrast, the ectoparasite control function of allopreening-in which one birds preens another-has not been rigorously tested. We infested captive pigeons with identical numbers of parasitic lice, and then compared rates of allopreening to the abun...

متن کاملMetabolic sensing and the brain: who, what, where, and how?
Unique subpopulations of specialized metabolic sensing neurons reside in a distributed network throughout the brain and respond to alterations in ambient levels of various metabolic substrates by altering their activity. Variations in local brain substrate levels reflect their transport across the blood- and cerebrospinal-brain barriers as well as local production by astrocytes. There are a num...
متن کاملAvocado Quality Assurance: Who? Where? When? How?
Avocado quality control is dealt with as a total process, commencing with an understanding of the physiological attributes of the fruit itself, including respiration, ethylene production, transpiration and the effects of step-down temperatures and time on quality. Orchard factors that may affect fruit quality are discussed briefly. These include factors such as irrigation, nutrition, mulching, ...
