Behavioral compatibility and reproductive outcomes in two distant populations of captive brown-headed cowbirds (Molothrus ater).
Increased understanding of geographic variation in courtship behavior in animal species can provide insight into the ways behavior may influence evolutionary change. Here, the relationship of geographic variation in courtship behavior to reproductive outcomes was tested in two distant and behaviorally distinct populations of brown-headed cowbirds, Molothrus ater, by comparing rates of copulatio...
متن کاملReproductive compatibility of prairie and montane populations of Dermacentor andersoni.
Genetic analysis of prairie and montane populations of Dermacentor andersoni (Stiles) originating from Alberta (AB) and British Columbia (BC), Canada, respectively, indicated limited gene flow (Nm <1) and a large amount of genetic differentiation (Fst = 0.49) between the populations. The prairie population also had a greater level of genetic diversity. Mating experiments indicated that females ...
متن کاملAnalysis of Soil Populations of Aspergillus flavus Link. from Pistachio Orchards in Iran for Vegetative Compatibility
One hundred-thirty soil isolates of A. flavus were collected from commercial pistachio orchards in two main production regions including Rafsanjan (Kerman Province, south-eastern of Iran) and Damghan (Semnan Province, central north of Iran) and assayed for vegetative compatibility groups (VCGs). The sixteen and twenty VCGs were identified for 41 and 37 nit-mutant producing isolates of A. flavus...
متن کاملOld stellar populations in distant radio galaxies
I describe the current status of our attempts to determine the age of the oldest known stellar populations at high redshift, in the red mJy radio galaxies 53W091 (z = 1.55) and 53W069 (z = 1.43). During the past year the original conclusion of Dunlop et al. (1996) that 53W091 is > 3 Gyr old has been questioned from two, basically orthogonal directions. First, reports that the near-infrared ligh...
متن کاملReproductive effort in viscous populations.
Here I study a kin selection model of reproductive effort, the allocation of resources to fecundity versus survival, in a patch-structured population. Breeding females remain in the same patch for life. Offspring have costly, partial long-distance dispersal and compete for breeding sites, which become vacant upon the death of previous occupants. The main result is that the evolutionarily stable...
