Glucocorticoids(GCs)are involved in the regulation of an animal's energetic state.Under stressful situations,they are part of the neuroendocrine response to cope with environmental challenges.Animals react to aversive...

Scatterhoarding rodents favor higher predation risks for cache sites:The potential for predators to influence the seed dispersal process被引量：5
《Integrative Zoology》2015年第3期257-266,共10页Michael A.STEELE Ghislain ROMPRÉ Jeffrey A.STRATFORD Hongmao ZHANG Matthew SUCHOCKI Shealyn MARINO 
We thank J.Healey and P.Lello for assistance with fieldwork and N.Lichti,R.K.Swihart and S.Agosta for earlier discussions on the potential for predators to impact patterns of cache placement by scatterhoarders and,in turn,the seed dispersal process.This study was in part supported by a Bullard Fellowship from Harvard Forest,Harvard University(to MAS),Wilkes University mentoring Fund,the U.S.National Science Foundation(DEB-12540642594)to MAS and the Howard Hughes Medical Institute to Wilkes University.
Scatterhoarding rodents often place caches in the open where pilferage rates are reduced,suggesting that they tradeoff higher risks of predation for more secure cache sites.We tested this hypothesis in two study syste...

Do black-furred animals compensate for high solar absorption with smaller hairs？ A test with a polymorphic squirrel species
《Current Zoology》2011年第6期731-736,共6页Melanie A. FRATTO Andrew K. DAVIS 
In polymorphic mammalian species that display multiple color forms, those with dark, or melanic pelage would be prone to overheating, especially if they live in warm climates, because their fur absorbs solar energy at...
