Mosquito landing rates on nesting American robins (Turdus migratorius).
We measured mosquito landing rates on adult and nestling American robins at nests with infrared cameras in Washington, D.C., and Maryland, United States. Mosquitoes landed on nesting robins almost exclusively between dusk and dawn. The mean number of mosquito landings per night was higher for adults (123.3 +/- SE 32.8) than nestlings (37.26 +/- 14.8). The fraction of mosquitoes landing at a nes...
متن کاملBehavioural tuning in a tropical amphibian along an altitudinal gradient.
Males of the coqui treefrog, Eleutherodactylus coqui, produce a distinct two-note 'co-qui' advertisement call from sunset to midnight throughout most of the year. Previous work established that both the spectrotemporal aspects of the call and the frequency of highest inner-ear sensitivity change with altitude above sea level. These variations are such that the frequency of the emitted co-note c...
متن کاملLeaf litter decomposition and microarthropod abundance along an altitudinal gradient
Mass loss rates of three types of leaf litter were measured along an altitudinal gradient at the Coweeta Hydrologic Laboratory, Macon County, North Carolina. Litterbags containing air dried litter from Quercus prinus L., Liriodendron tulipifera L., and Rhododendron maximum L. were placed in five plots along the gradient and sampled monthly. Microarthropods were extracted and sorted, and litter ...
متن کاملAsymmetrical local adaptation of maize landraces along an altitudinal gradient
Crop landraces are managed populations that evolve in response to gene flow and selection. Cross-pollination among fields, seed sharing by farmers, and selection by management and environmental conditions play roles in shaping crop characteristics. We used common gardens to explore the local adaptation of maize (Zea mays ssp. mays) landrace populations from Chiapas, Mexico to altitude. We sowed...
متن کاملWhich egg features predict egg rejection responses in American robins? Replicating Rothstein's (1982) study
Rothstein (Behavioral Ecology and Sociobiology, 11, 1982, 229) was one of the first comprehensive studies to examine how different egg features influence egg rejection behaviors of avian brood parasite-hosts. The methods and conclusions of Rothstein (1982) laid the foundation for subsequent experimental brood parasitism studies over the past thirty years, but its results have never been evaluat...
