Genomic architecture of phenotypic divergence between two hybridizing plant species along an elevational gradient (2016)
Journal Article
Brennan, A., Hiscock, S., & Abbott, R. (2016). Genomic architecture of phenotypic divergence between two hybridizing plant species along an elevational gradient. AoB PLANTS, 8, Article plw022. https://doi.org/10.1093/aobpla/plw022

Knowledge of the genetic basis of phenotypic divergence between species and how such divergence is caused and maintained is crucial to an understanding of speciation and the generation of biodiversity. The hybrid zone between Senecio aethnensis and S... Read More about Genomic architecture of phenotypic divergence between two hybridizing plant species along an elevational gradient.

Hybridization due to changing species distributions: adding problems or solutions to conservation of biodiversity during global change? (2015)
Journal Article
Brennan, A. C., Woodward, G., Seehausen, O., Munoz-Fuentes, V., Moritz, C., Guelmami, A., …Edelaar, P. (2015). Hybridization due to changing species distributions: adding problems or solutions to conservation of biodiversity during global change?. Evolutionary Ecology Research, 16(6), 475-491

Background: Due to increasing global change, the rate of hybridization appears to be increasing. Question: Is hybridization adding problems or solutions to the effects of global change on biodiversity? Methods: We divided ourselves into two independe...

Altitudinal gradients, plant hybrid zones and evolutionary novelty (2014)
Journal Article
Abbott, R., & Brennan, A. (2014). Altitudinal gradients, plant hybrid zones and evolutionary novelty. Philosophical Transactions of the Royal Society B: Biological Sciences, 369(1648), Article 20130346. https://doi.org/10.1098/rstb.2013.0346

Altitudinal gradients are characterized by steep changes of the physical and biotic environment that present challenges to plant adaptation throughout large parts of the world. Hybrid zones may form where related species inhabit different neighbourin... Read More about Altitudinal gradients, plant hybrid zones and evolutionary novelty.

Interspecific crossing and genetic mapping reveal intrinsic genomic incompatibility between two Senecio species that form a hybrid zone on Mount Etna, Sicily (2014)
Journal Article
Brennan, A., Hiscock, S., & Abbott, R. (2014). Interspecific crossing and genetic mapping reveal intrinsic genomic incompatibility between two Senecio species that form a hybrid zone on Mount Etna, Sicily. Heredity, 113, 195-204. https://doi.org/10.1038/hdy.2014.14

Studies of hybridizing species can reveal much about the genetic basis and maintenance of species divergence in the face of gene flow. Here we report a genetic segregation and linkage analysis conducted on F2 progeny of a reciprocal cross between Sen...

The genetic structure of Arabidopsis thaliana in the south-western Mediterranean range reveals a shared history between North Africa and southern Europe (2014)
Journal Article
Brennan, A., Méndez-Vigo, B., Haddioui, A., Martínez-Zapater, J., Picó, F., & Alonso-Blanco, C. (2014). The genetic structure of Arabidopsis thaliana in the south-western Mediterranean range reveals a shared history between North Africa and southern Europe. BMC Plant Biology, 14, Article 17. https://doi.org/10.1186/1471-2229-14-17

Background Deciphering the genetic structure of Arabidopsis thaliana diversity across its geographic range provides the bases for elucidating the demographic history of this model plant. Despite the unique A. thaliana genomic resources currently avai...
