Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae). [PDF]

Mol Ecol
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

Anthropogenic or Natural Dispersal: Case of the Spiny-Tailed Iguanas (<i>Ctenosaura</i>) on Clarion Island, Mexico. [PDF]

Ecol Evol
Species can colonize oceanic islands by both natural and human‐assisted dispersal and human‐caused species introductions have had catastrophic effects on ecosystems around the world. The Spiny‐tailed Iguanas inhabiting Clarion Island were previously considered introduced. Molecular data and analyses support iguanas' arrival on Clarion Island by natural

Chromosomal Inversion Associated With Diet Differences in Common Quails Sharing Wintering Grounds. [PDF]

Ecol Evol
A large chromosomal inversion in common quails (Coturnix coturnix) is associated with phenotypic traits. In a wintering population in southern Spain, we found all three karyotypes coexisting but showing differences in migratory behavior and diet, as exemplified by the isotopic signature.

Meristic co-evolution and genomic co-localization of lateral line scales and vertebrae in Central American cichlid fishes. [PDF]

Ecol Evol
We dissect the co‐evolution and genetic architecture of lateral line scale counts and vertebrae numbers in Neotropical Heroine cichlids. Our phylogenetic comparative analyses recovered a positive correlation between these two traits. Furthermore, our qualitative traits locus (QTL) analyses identified significant genomic co‐localized associations for ...

The importance of cryptic diversity in the conservation of wide‐ranging species: The red‐footed tortoise Chelonoidis carbonarius in Colombia

Molecular Ecology, Volume 32, Issue 16, Page 4531-4545, August 2023., 2023
Abstract Wide‐ranging species are seldom considered conservation priorities, yet they have the potential to harbour genetically deeply differentiated units across environments or ecological barriers, including some that warrant taxonomic recognition. Documenting such cryptic genetic diversity is especially important for wide‐ranging species that are in

Replicate contact zones suggest a limited role of plumage in reproductive isolation among subspecies of the variable seedeater (Sporophila corvina)

Molecular Ecology, Volume 32, Issue 13, Page 3586-3604, July 2023., 2023
Abstract After establishing secondary contact, recently diverged populations may remain reproductively isolated or may hybridize to a varying extent depending on factors such as hybrid fitness and the strength of assortative mating. Here, we used genomic and phenotypic data from three independent contact zones between subspecies of the variable ...

Estimativa da variabilidade genética em linhagens de tilápia do Nilo (Oreochromis niloticus) com a técnica de RAPD - DOI: 10.4025/actascianimsci.v27i1.1236

Acta Scientiarum: Animal Sciences, 2008
A variabilidade genética é essencial para que se possa obter melhoramento genético e, portanto, é de grande importância a sua estimação. Desta forma, o objetivo do presente experimento foi estimar, pela técnica Random Amplified Polymorphic DNA (RAPD), a ...

MARCADORES RAPD NA ANÁLISE DA DIVERGÊNCIA GENÉTICA ENTRE RAÇAS DE BOVINOS E NÚMERO DE LOCOS NECESSÁRIOS PARA A ESTABILIDADE DA DIVERGÊNCIA ESTIMADA

Ciência Animal Brasileira, 2006
Diversos marcadores moleculares vêm auxiliando tanto geneticistas como melhoristas na detecção da variabilidade genética das populações. O incremento na capacidade computacional tem permitido também a otimização dos delineamentos, reduzindo os custos e o
