DOI: 10.1002/ajb2.16067
Abstract: Abstract Premise Genetic variation influences the potential for evolution to rescue populations from impacts of environmental change. Most studies of genetic variation in fitness‐related traits focus on either vegetative or floral traits, with few on… read more here.

DOI: 10.1002/ece3.7768
Abstract: Abstract The saltmarsh sparrow Ammospiza caudacuta and Nelson's sparrow A. nelsoni differ in ecological niche, mating behavior, and plumage, but they hybridize where their breeding distributions overlap. In this advanced hybrid zone, past interbreeding and… read more here.

DOI: 10.1002/ece3.9700
Abstract: Abstract Natural hybridization of plants can result in many outcomes with several evolutionary consequences, such as hybrid speciation and introgression. Natural hybrid zones can arise in mountain systems as a result of fluctuating climate during… read more here.

DOI: 10.1002/ece3.9863
Abstract: Abstract Hybrid zones are natural experiments for the study of avian evolution. Hybrid zones can be dynamic, moving as species adjust to new climates and habitats, with unknown implications for species and speciation. There are… read more here.

DOI: 10.1016/j.cub.2017.11.029
Abstract: Climate change has been implicated as driving shifts of hybridizing species' range limits [1, 2]. Whether and how much hybrid zones move depends on the relative fitness of hybridzing species under changing conditions [3, 4].… read more here.

DOI: 10.1016/j.jcz.2021.07.001
Abstract: Abstract Diploid Odontophrynus cordobae and tetraploid Odontophrynus americanus coexist in syntopy in central Argentina, and recently a hybrid zone between them with numerous triploid individuals has been reported. Furthermore, hybrid polyploids with odd numbers of… read more here.

DOI: 10.1093/aob/mcy072
Abstract: Background and Aims Clines in traits across hybrid zones reflect a balance between natural selection and gene flow. Changes over time in average values for traits, and especially the shapes of their clines, are rarely… read more here.

DOI: 10.1111/eva.12795
Abstract: A lack of optimal gene combinations, as well as low levels of genetic diversity, is often associated with the formation of species range margins. Conservation efforts rely on predictive modelling using abiotic variables and assessments… read more here.
