DOI: 10.1002/ajb2.16043
Abstract: PREMISE OF THE STUDY The successful establishment of polyploid species is hypothesized to be promoted by niche differentiation from the parental species, or by range shifts during climate oscillations. However, few studies have considered both… read more here.

Habitat-based isolating barriers are not strong in the speciation of ecologically divergent squirrels (Tamiasciurus douglasii and T. hudsonicus)

DOI: 10.1007/s00265-020-2814-5
Abstract: Adaptations to different environments between closely related species can be important drivers of reproductive isolation during speciation due to either habitat isolation between species or reduced fitness in hybrids that possess suboptimal adaptations. Hybrid zones… 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: 10.1038/s41437-022-00498-1
Abstract: Investigating the origin of parthenogenesis through interspecific hybridization can provide insight into how meiosis may be altered by genetic incompatibilities, which is fundamental for our understanding of the formation of reproductive barriers. Yet the genetic… read more here.

DOI: 10.1038/s41598-022-08635-w
Abstract: Interspecies hybrids can express phenotypic traits far outside the range of parental species. The atypical traits of hybrids provide insight into differences in the factors that regulate the expression of these traits in the parental… read more here.

DOI: 10.1086/721445
Abstract: Pigments such as melanin are most often associated with the surface of an organism, providing functions such as coloration and protection from UV radiation. However, the internal organs of some species also contain melanin. Internal… read more here.

DOI: 10.1093/sysbio/syad009
Abstract: Phylogenetic analysis of polyploid hybrid species has long posed a formidable challenge as it requires the ability to distinguish between alleles of different ancestral origins in order to disentangle their individual evolutionary history. This problem… read more here.

DOI: 10.1186/s12862-020-01690-9
Abstract: Background The majority of parthenogenetic vertebrates derive from hybridization between sexually reproducing species, but the exact number of hybridization events ancestral to currently extant clonal lineages is difficult to determine. Usually, we do not know… read more here.
