Genomic footprints of recovery in the European bison

Tom Druet, Kamil Oleński, Laurence Flori, Amandine Bertrand, Wanda Olech, Malgorzata Tokarska, Stanislaw Kaminski & Mathieu Gautier
After extinction in the wild in the beginning of the twentieth century, the European bison has been successfully recovered in two distinct genetic lines from only twelve and seven captive founders. We here aimed at characterizing the levels of realized inbreeding in these two restored lines to provide empirical insights into the genomic footprints left by population recovery from a small number of founders. To that end, we genotyped 183 European bison born over the...

From refugia to contact: pine processionary moth hybrid zone in a complex biogeographic setting

Kahraman İpekdal, Christian Burban, Laure Sauné, Andrea Battisti & Carole Kerdelhué
Contact zones occur at the crossroad between specific dispersal routes and are facilitated by biogeographic discontinuities. Here we focused on two Lepidoptera sister species that come in contact near the Turkish Straits System (TSS). We aimed to infer their phylogeographic histories in the Eastern Mediterranean and finely analyse their co-occurrence and hybridisation patterns in this biogeographical context. We used molecular mitochondrial and nuclear markers to study 224 individuals from 42 localities. We used discordances between...

Associational resistance to both insect and pathogen damage in mixed forests is modulated by tree neighbour identity and drought

Elsa Field, Bastien Castagneyrol, Melanie Gibbs, Hervé Jactel, Nadia Barsoum, Karsten Schonrogge & Andrew Hector
Tree health declines can be caused by interactions between pests and pathogens and many studies have shown a reduction in their damage in mixed species forests compared to monocultures. Yet few authors have considered tree diversity effects on both groups simultaneously. Moreover, it is unclear whether diversity effects on tree pests and pathogens are robust to changes in abiotic conditions, such as drought. We addressed tree diversity effects on foliar insect herbivory, oak powdery mildew...

Drivers of longitudinal telomere dynamics in the long-lived bat species, Myotis myotis

Nicole Foley, Eric Petit, Thomas Brazier, John Finarelli, Graham Hughes, Frederic Touzalin, Sebastien Puechmaille & Emma Teeling
Age related telomere shortening is considered a hallmark of the ageing process. However, a recent cross-sectional ageing study of relative telomere length (rTL) in bats failed to detect a relationship between rTL and age in the long-lived genus Myotis (M. myotis and M. bechsteinii), suggesting some other factors are responsible for driving telomere dynamics in these species. Here, we test if longitudinal rTL data show signatures of age-associated telomere attrition in M. myotis and differentiate...

Disentangling the assembly mechanisms of ant cuticular bacterial communities of two Amazonian ant species sharing a common arboreal nest

Caroline Birer, Corrie S. Moreau, Niklas Tysklind, Lucie Zinger & Christophe Duplais
Bacteria living on the cuticle of ants are generally studied for their protective role against pathogens, especially in the clade of fungus-growing ants. However, little is known of the diversity of cuticular bacteria in other ant host species, as well as of the mechanisms leading to the composition of these communities. Here, we used 16S rRNA gene amplicon sequencing to study the influence of host species, species interactions, and the pool of bacteria from the...

Pedigree-free quantitative genetic approach provides evidence for heritability of movement tactics in wild roe deer

Laura Gervais, Aidan.J Mark Hewison, Nicolas Morellet, Maria Bernard, Joël Merlet, Bruno Cargnelutti, Yannick Chaval, Benoit Pujol & Erwan QUEMERE
Assessing the evolutionary potential of animal populations in the wild is crucial to understanding how they may respond to selection mediated by rapid environmental change (e.g. habitat loss and fragmentation). A growing number of studies have investigated the adaptive role of behaviour, but assessments of its genetic basis in a natural setting remain scarce. We combined intensive biologging technology with genome-wide data and a pedigree-free quantitative genetic approach to quantify repeatability, heritability and evolvability for...
