Potential Adaptive Introgression From Dogs in Iberian Grey Wolves (Canis lupus). [PDF]

Mol Ecol
ABSTRACT Invading species along with increased anthropogenization may lead to hybridization events between wild species and closely related domesticates. As a consequence, wild species may carry introgressed alleles from domestic species, which is generally assumed to yield adverse effects in wild populations.

Evidence of introgression amid phylogenetic conflict in Brachyotum, a plant radiation from the Tropical Andes. [PDF]

Am J Bot
Abstract Premise The species‐rich flora of Tropical Andes underwent multiple rapid and recent diversifications, yet resolving their evolutionary histories remains challenging despite increasing phylogenomic data. Here, we examined phylogenomic conflict in Brachyotum (Melastomataceae) to identify sources preventing its resolution.

Simulating the efficacy of wolf-dog hybridization management with individual-based modeling. [PDF]

Conserv Biol
In the photo, an introgressed adult wolf–dog in the Northern Apennines, Italy, not far from the city of Bologna. Part of a research program, this male has been sterilized and released back in its own pack with a Global Positioning Collar. Abstract Introgressive hybridization between wolves and dogs is a conservation concern due to its potentially ...

Ancient hybridization and phylogenetic discordance: Exploring evolutionary complexity in Asteraceae. [PDF]

Appl Plant Sci
Abstract Premise Conflicting phylogenetic signals are common in plant phylogenomics and often reflect evolutionary histories shaped by processes like hybridization, incomplete lineage sorting, and whole‐genome duplication (WGD). We aimed to identify and assess these complex processes in the hyper‐diverse family Asteraceae to offer insight into the ...

Publication and use of genetic tools in conservation management applications—A systematic review

Journal of Applied Ecology, Volume 60, Issue 8, Page 1522-1536, August 2023., 2023
Conservation genetics tools must be brought to the forefront of conservation policy and management. Users should support the use of systems and accessible databases to increase the uptake of genetics tools for conservation in applied management decisions for wildlife, reducing barriers to disseminating the results to other end users and interested ...

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 ...

Challenges and a call to action for protecting European red wood ants

Conservation Biology, Volume 36, Issue 6, December 2022., 2022
Abstract Red wood ants (RWAs) are a group of keystone species widespread in temperate and boreal forests of the Northern Hemisphere. Despite this, there is increasing evidence of local declines and extinctions. We reviewed the current protection status of RWAs throughout Europe and their International Union for the Conservation of Nature (IUCN) threat ...

Individual‐based simulations of genome evolution with ancestry: The GenomeAdmixR R package

Methods in Ecology and Evolution, Volume 12, Issue 8, Page 1346-1357, August 2021., 2021
Abstract Hybridization between populations or species results in a mosaic of the two parental genomes. This and other types of genome admixture have received increasing attention for their implications in speciation, human evolution, Evolve and Resequence (E&R) and genetic mapping.

Safeguarding the genetic integrity of native pollinators requires stronger regulations on commercial lines

Ecological Solutions and Evidence, Volume 1, Issue 1, July 2020., 2020
Wild and commercial bumblebees from different subspecies are hybridizing. This genetic introgression is widespread and threatens local adaptations. Stronger regulations are needed to safeguard pollinators' genetic diversity. Abstract Every year more than 1 million commercial bumblebee colonies are deployed in greenhouses worldwide for their pollination
