Premigratory fat metabolism in hummingbirds： A Rumsfeldian approach: 《Current Zoology》2013年第3期371-380,共10页Raul K. SUAREZ; I am deeply grateful to EW. Hochachka, C.L. Gass, K.C. Welch, Jr., J.R.B. Lighton, C. Martinez del Rio and O. Mathieu-Costello for their contributions to the research that led to the ideas presented and questions raised in this paper. Research on which this article is based was funded by the U.S. National Science Foundation （IOB 0517694）.; Hummingbird migration is a remarkable feat, given the small body sizes of migratory species, their high metabolic rates during flight and the long distances traveled using fat to fuel the effort. Equally remarkable is...; 关键词：Lipid synthesis Metabolic rate Metabolic regulation Muscle energy metabolism Sugar oxidation

Memory for location and visual cues in white-eared hummingbirds Hylocharis leucotis被引量：1: 《Current Zoology》2011年第4期468-476,共9页Guillermo PEREZ Carlos LARA Jose VICCON-PALE Martha SIGNORET-POILLON; In nature hummingbirds face floral resources whose availability, quality and quantity can vary spatially and temporally. Thus, they must constantly make foraging decisions about which patches, plants and flowers to vi...; 关键词：Visual cues LOCATION White-eared hummingbird FORAGING

Wing, tail, and vocal contributions to the complex acoustic signals of courting Calliope hummingbirds被引量：1: 《Current Zoology》2011年第2期187-196,共10页Christopher James CLARK; Acknowledgments I thank S. Weinstein, A. Varma, and T. Feo for assistance in the field; L. Benedict and T. Libby for use of equipment, J. Brown for accommodations, and G. Weston-Murphy for assistance with the wind tunnel. Walter Nussbaumer kindly allowed use of a photo. The manuscript was improved by comments from T. Feo and two anonymous reviewers. The research was supported by the MVZ and National Science Foundation IOS-090353 to R. Prum.; Multi-component signals contain multiple signal parts expressed in the same physical modality. One way to identify individual components is if they are produced by different physical mechanisms. Here, I studied the me...; 关键词：Calliope Hummingbird COURTSHIP MULTICOMPONENT Signal Sonation Wind Tunnel
