Reintroducing a regionally extinct butterfly? Genetic, climatic and microbiological data can make it possible
Science is full of SHEroes whose passion, work and creativity inspired Evolutionary Biologists of today.
As part of our commitment with society, the Institute of Evolutionary Biology (IBE, CSIC-UPF) wants to give credit and visibility to the achievements of female scientists in evolution.
To that aim, we launched the campaign #WhoisyourSHEro to share stories of women who had an impact in our researchers' scientific career through our social media and website.
The campaign keeps on moving as more and more women in evolution are inspiring the IBE community.
You can join the conversation through social media under the hashtag #WhoisyourSHEro.
With the collaboration of the Spanish Foundation for Science and Technology - Ministry of Science and Innovation.

Reintroducing a regionally extinct butterfly? Genetic, climatic and microbiological data can make it possible
Reintroducing a regionally extinct butterfly? Genetic, climatic and microbiological data can make it possible
A program to reintroduce in Hungary the butterfly Melanargia russiae (Esper’s marbled white), extirpated from the country over 100 years ago, was recently approved. Research shows that populations from eastern Ukraine are the most suitable as source population for the reintroduction.
Materials stored in museum collections can provide unique opportunities to document historical genetic diversity and help direct conservation, as shown in research published in the journal Conservation Biology with IBE researchers Vlad Dinca and Roger Vila as first and corresponding authors.
Mitochondrial DNA data from over 100-year-old museum specimens from extinct Melanargia russiae (Esper’s marbled white) extinct Hungarian populations were analysed. Results were compared with a comprehensive genetic data set that included representatives from across the distribution of Melanargia russiae. This analysis made it possible for the researchers to ascertain the extant populations that were genetically most similar to the Hungarian sites targeted for reintroduction.
Scientists then assessed which areas with extant populations were climatically more similar to the Hungarian sites targeted for reintroduction, and finally screened specimens for the presence of the widespread bacterial endosymbiont Wolbachia.
The paper concludes that the populations used for reintroduction to Hungary should belong to the Eurasian lineage; preferably from eastern Ukraine (since they are genetically close and living in areas with the highest climatic similarity).
Conservation aims to prevent loss of species, their genetic diversity and habitats. Increasingly, the introduction of species that are locally or globally extinct in the wild is being taken, these efforts having had varying success. In 2016, a plan focusing on the reintroduction of Melanargia russiae in Hungary was approved by the nature conservation authorities.
