Culturally Hybrid Zones and School Literacy Practices

Signum: Estudos da Linguagem, 2021
Based on data generated for an ethnographic research carried out in 2018 - which aimed at comprehending how literacy practices developed in Portuguese lessons delivered to senioryear students of a public high school dialogue with literacy practices in

Salinity, not genetic incompatibilities, limits the establishment of the invasive hybrid cattail Typha × glauca in coastal wetlands

Ecology and Evolution, 2020
Hybrids of a single pair of parent species can be much more common in some geographical regions than in others. The reasons for this are not well understood, but could help explain processes such as species diversification or the range expansion of ...

Temporal and spatial dynamics of competitive parapatry in chewing lice

Ecology and Evolution, 2019
We synthesize observations from 1979 to 2016 of a contact zone involving two subspecies of pocket gophers (Thomomys bottae connectens and T. b. opulentus) and their respective chewing lice (Geomydoecus aurei and G.

Landscape resistance constrains hybridization across contact zones in a reproductively and morphologically polymorphic salamander

Scientific Reports, 2021
Explicitly accounting for phenotypic differentiation together with environmental heterogeneity is crucial to understand the evolutionary dynamics in hybrid zones.

Phylogeography and species limits in the red‐shouldered hawk (Buteo lineatus): Characterization of the Northern Florida Suture Zone in birds

Ecology and Evolution, 2019
The North American red‐shouldered hawk, Buteo lineatus, is comprised of two widely allopatric eastern and western populations with an additional well‐marked subspecies in the Florida peninsula.

Phenotypic variation across chromosomal hybrid zones of the common shrew (Sorex araneus) indicates reduced gene flow. [PDF]

PLoS ONE, 2013
Sorex araneus, the Common shrew, is a species with more than 70 karyotypic races, many of which form parapatric hybrid zones, making it a model for studying chromosomal speciation.

Tracing the footprints of a moving hybrid zone under a demographic history of speciation with gene flow

Evolutionary Applications, 2020
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 of genetic ...

speciation through asexuality in fish: postzygotic reproductive isolation may be completed in spite of fertility of hybrids

Frontiers in Marine Science, 2015
Speciation process often occurs in the face of hybridisation between forming species. Hybrid genomic constitution of many clonal organisms including fish, amphibians and reptiles also indicates tight linkage between hybridization, clonality and ...

Temporal stability of the hybrid zone between Calocitta magpie‐jays revealed through comparison of museum specimens and iNaturalist photos

Ecology and Evolution, 2023
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.

Four Species Linked by Three Hybrid Zones: Two Instances of Repeated Hybridization in One Species Group (Genus Liolaemus)

Frontiers in Ecology and Evolution, 2021
Hybridization is an evolutionary process that can generate diverse outcomes, such as reinforcing species boundaries, generating new species, or facilitating the introgression of locally-adapted alleles into new genomic backgrounds.
