WHAT MOLECULES CAN TELL US ABOUT POPULATIONS: CHOOSING ANDUSING A MOLECULAR MARKER
TLDR
This work evaluates the application of several major techniques (protein electrophoresis, nuclear and mitochondrial RFLPs, minisatellite and microsatellite VNTRs, RAPDs, and DNA sequencing) to an array of questions regarding individual identification, exclusion and assignment of parentage, and various levels of population structure. Expand
Worldwide Phylogenetic Relationship of Avian Poxviruses
TLDR
This study provides a broad and comprehensive phylogenetic analysis of the Avipoxvirus genus, an ecologically and environmentally important viral group, to formulate a genome sequencing strategy that will clarify avipoxVirus taxonomy. Expand
CORRELATIONAL SELECTION LEADS TO GENETIC INTEGRATION OF BODY SIZE AND AN ATTRACTIVE PLUMAGE TRAIT IN DARK‐EYED JUNCOS
TLDR
This is the first study to show both genetic correlations between sexually selected traits and currently acting correlational sexual selection, and it is suggested that correlationalSexual selection frequently may be an important mechanism for maintaining the honesty of sexual signals. Expand
Testosterone affects reproductive success by influencing extra–pair fertilizations in male dark–eyed juncos (Aves: Junco hyemalis)
TLDR
This first hormonal manipulation of an avian phenotype shown to have influenced male RS through EPFs suggests that testosterone may have mediated the evolution of inter– and intraspecific differences in allocation of reproductive effort to mate attraction and parental care. Expand
Disease ecology in the Galápagos Hawk (Buteo galapagoensis): host genetic diversity, parasite load and natural antibodies
TLDR
This is the first study linking inbreeding, innate immunity and parasite load in an endemic, in situ wildlife population and provides a clear framework for assessment of disease risk in a Galápagos endemic. Expand
Plasmodium blood parasite found in endangered Galapagos penguins (Spheniscus mendiculus)
TLDR
Phylogenetic analyses place this parasite, recovered from endangered Galapagos penguins (Spheniscus mendiculus), within the genus Plas modium, and suggest a close relationship to some of the most dangerous lineages of Plasmodium that have been known to cause severe mortality and morbidity in captive penguin populations. Expand
Flexible social structure of a desert rodent, Rhombomys opimus: philopatry, kinship, and ecological constraints
TLDR
It is concluded that great gerbils are facultatively social and may be adaptive in unpredictable desert conditions because they live solitarily under conditions of limited food and high mortality that disrupt social behavior and group formation. Expand
Physiological Effects on Demography: A Long‐Term Experimental Study of Testosterone’s Effects on Fitness
TLDR
The higher fitness of testosterone‐treated males in the absence of a comparable natural phenotype suggests that the natural phenotype may be constrained and the negative social effects on offspring and mates suggest that these effects might prevent high‐testosterone phenotypes from spreading in the population. Expand
Parasites reduce attractiveness and reproductive success in male grain beetles
TLDR
Female preference for odours produced by male grain beetles, Tenebrio molitor, that were either infected by a tapeworm, Hymenolepis diminuta, or uninfected, is measured, indicating parasitic infection inflicts multiple costs to males. Expand
Phylogeography of the Galápagos hawk (Buteo galapagoensis): a recent arrival to the Galápagos Islands.
TLDR
The recent arrival, genetic isolation, and phenotypic differentiation among populations suggest that the Galápagos hawk, a rather new species itself, is in the earliest stages of further divergence. Expand
