Evolution and plasticity of morph-specific integration in the bull-headed dung beetle Onthophagus taurus

Patrick T. Rohner, Anna Macagno & Armin Moczek
Developmental and evolutionary processes underlying phenotypic variation frequently target several traits simultaneously, thereby causing covariation, or integration, among phenotypes. While phenotypic integration can be neutral, correlational selection can drive adaptive covariation. Especially the evolution and development of exaggerated secondary sexual traits may require the adjustment of other traits that support, compensate for, or otherwise function in a concerted manner. Although phenotypic integration is ubiquitous, the interplay between genetic, developmental, and ecological conditions in shaping integration...

Local adaptation from afar: migratory bird populations diverge in the initiation of reproductive timing while wintering in sympatry

Sarah Wanamaker, Devraj Singh, Allison Byrd, Tara Smiley & Ellen Ketterson
The initiation of reproduction in many seasonally breeding animals is controlled by photoperiod and tends to be clinal: populations at higher latitudes breed later than those at lower latitudes, often reflecting a higher photoperiodic threshold. Migratory animals presumably time reproduction to match conditions at their breeding grounds at least in part by cues perceived on their wintering grounds. We asked how closely related dark-eyed junco (Junco hyemalis) populations that overwinter in sympatry but breed in...

The macroecology and evolution of avian competence for Borrelia burgdorferi

Daniel Becker & Barbara Han
Aim: Predicting novel reservoirs of zoonotic pathogens would be improved by identifying inter-specific drivers of host competence, the ability to transmit pathogens to new hosts or vectors. Tick-borne pathogens can provide a useful model system, as larvae become infected only when feeding on a competent host during their first bloodmeal. For tick-borne diseases, competence has been best studied for Borrelia burgdorferi sensu lato (Bbsl), which causes Lyme borreliosis. Major reservoirs include several small mammal species,...
