Using age‐ratios to investigate the status of two Siberian Phylloscopus species in Europe

Ibis, EarlyView.
Distinguishing between vagrancy and regular migration has proved to be challenging as vagrants may, in theory, act as pioneers in the establishment of new migration routes. Because migratory songbirds tend to follow the same orientation and migration route throughout their lives, age assessment can help to distinguish individuals which have already ...

Similar Morphologies but Different Origins: Hybrid Status of Two More Semi-creeping Taxa of Melastoma

Frontiers in Plant Science, 2017
Inferring the origins of hybrid taxa based on morphology alone is difficult because morphologically similar hybrids can arise from hybridization between different populations of the same parental species or be produced by hybridization of different ...

Morphological differences between wild and game‐farm Mallards (Anas platyrhynchos) in North America

Ibis, EarlyView.
Large‐scale releases of domesticated, game‐farm Mallards Anas platyrhynchos to supplement wild populations have resulted in widespread introgressive hybridization that changed the genetic constitution of wild populations in eastern North America.

Genetic admixture despite ecological segregation in a North African sparrow hybrid zone (Aves, Passeriformes, Passer domesticus × Passer hispaniolensis)

Ecology and Evolution, 2019
Under different environmental conditions, hybridization between the same species might result in different patterns of genetic admixture. Particularly, species pairs with large distribution ranges and long evolutionary history may have experienced ...

Nuclear compensatory evolution driven by mito-nuclear incompatibilities [PDF]

Mitochondrial function relies on the coordinated expression of mitochondrial and nuclear genes, exhibiting remarkable resilience regardless the susceptibility of mitochondrial DNA (mtDNA) to accumulate harmful mutations. A suggested mechanism for preserving this mito-nuclear compatibility is the nuclear compensation, where deleterious mitochondrial ...

Single‐Step Breeding Value Estimations and Optimum Contribution Selection in Endangered Dual‐Purpose German Black Pied Cattle (DSN) Using a Breed Specific SNP Chip

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The aims of the present study were to perform single‐step genomic predictions in the dual‐purpose German Black Pied cattle (DSN) breed considering a DSN specific SNP chip (DSN_200 K), and to use the corresponding estimated breeding values (EBV) in ongoing optimum genetic contribution (OGC) selection.

Genomic Signatures of Ancient Vicariance in Host‐Specific Fungal Endophytes Across the Soltis Line in the Pacific Northwest

Journal of Biogeography, EarlyView.
ABSTRACT Aim Foliar fungal endophytes are a highly diverse component of most plants, both in terms of taxonomic composition and function. Investigating the biogeography of these microbial symbionts in well‐studied regions complements our understanding of the patterns and processes already inferred for animals and plants.
