Phylogeography and Adaptive Plumage Evolution in Central American Subspecies of the Slate-Throated Redstart (Myioborus miniatus)

Pérez-Emán, J. L., Mumme, R. L., Jablonski, P. G. The Slate-throated Redstart (Myioborus miniatus) is a common warbler of montane forests from northern Mexico to Argentina. We examined phylogenetic structure and plumage pattern in relation to subspecific taxonomy across the broad geographic range of this species. Phylogenetic analysis of two complete mitochondrial protein-coding genes

Unusual Pattern of Sex-Specific Mortality in Relation to Initial Brood Sex Composition in Black-billed Magpie (Pica pica)

Lee, S. I., Hwang, Y., Lee, J., & Choe, J. C. In sexually size-dimorphic species, brood sex composition may exert differential effects on sex-specific mortality. We investigated the sex-specific mortality and body condition in relation to brood sex composition in nestlings of the black-billed magpie Pica pica. Neither significantly sex-biased production at hatching nor

Parental Provisioning in Response to Natural Variation of Brood Size in the Black-Billed Magpie (Pica pica)

Lee, S. I., Choi, J., Jablonski, P. G., & Choe, J. C. Natural selection will favor parents who adjust their effort in relation to the fitness costs and benefits from the current brood. In this study, we investigated how magpie parents adjust provisioning effort based on the number of nestlings in the brood, by

The consequences of winter flock demography for genetic structure and inbreeding in Vinous-throated Parrtbills Paradoxornis webbianus

Lee, J. W., Simeoni, M., Burke, T., & Hatchwell, B. J. The adaptive significance of flocking behaviour has been intensively studied, especially among birds, but the demography and genetic structure of winter flocks is poorly understood, despite their importance for many biological processes. For three successive winters, we studied the demography and genetic structure

Natal dispersal and philopatry in a group-living but noncooperative passerine bird, the vinous-throated parrotbill

Lee, J. W., Lee, Y. K., & Hatchwell, B. J. Dispersal is a key factor affecting the dynamics and genetic structure of populations. Patterns of natal dispersal vary widely depending on the selection pressures that each species encounters, but the underlying factors determining this variation are poorly understood. We studied the pattern of natal

Parental provisioning behaviour in a flock-living passerine, the Vinous-throated Parrotbill Paradoxornis webbianus

Lee, J. W., Kim, H. Y., & Hatchwell, B. J. The amount of food delivered by parents to their chicks is affected by various life history traits as well as environmental and social factors, and this investment ultimately determines the current and future fitness of parents and their offspring. We studied parental provisioning behaviour

Male water striders attract predators to intimidate females into copulation

Han, C. S., & Jablonski, P. G. Despite recent advances in our understanding of sexual conflict and antagonistic coevolution between sexes, the role of interspecific interactions, such as predation, in these evolutionary processes remains unclear. In this paper, we present a new male mating strategy whereby a male water strider Gerris gracilicornis intimidates a

New methods to identify conserved microsatellite loci and develop primer sets of high cross-species utility

Dawson, D.A., Horsburgh, G.J., KÜPPER, C., Stewart, I.R., Ball, A.D., Durrant, K.L., Hansson, B., Bacon, I.D.A., Bird, S., Klein, A. and Krupa, A.P. We have developed a new approach to create microsatellite primer sets that have high utility across a wide range of species. The success of this method was demonstrated using birds. We

Size-assortative mating and sexual size dimorphism are predictable from simple mechanics of mate-grasping behavior

Han, C. S., Jablonski, P. G., Kim, B., & Park, F. C. A major challenge in evolutionary biology is to understand the typically complex interactions between diverse counter-balancing factors of Darwinian selection for size assortative mating and sexual size dimorphism. It appears that rarely a simple mechanism could provide a major explanation of these

Extrapair paternity in a flock-living passerine, the Vinous-throated Parrotbill Paradoxornis webbianus

Lee, J. W., Kim, M. S., Burke, T., & Hatchwell, B. J. Understanding the factors that affect the occurrence of extrapair paternity (EPP) is one of the central issues in sexual selection. We investigated genetic parentage and the ecological factors affecting patterns of EPP in the Vinous-throated Parrotbill, Paradoxornis webbianus, a flock-living species with
