Human-mediated introgression and Varroa destructor shaped the genetic structure...
Henriques, Dora; Lopes, Ana; Low, Matthew; Pinto, M. AliceThe evolutionary trajectory of island populations can be rapidly altered by human-mediated migration, a process further exacerbated when immigrants introduce invasive parasites, creating new selective pressures. Using customised SNP panels constructed with genome-wide diagnostic loci, we describe the genetic changes in honey bee populations inhabiting the Azores archipelago. As part of a breeding initiative in ...
Origins, diversity, and adaptive evolution of DWV in the honey bees of the Azor...
Lopes, Ana Rita; Low, Matthew; Martín-Hernández, Raquel; Pinto, M. Alice; Miranda, Joachim R. deDeformed wing virus (DWV) is a honey bee virus, whose emergence from relative obscurity is driven by the recent host-switch, adaptation, and global dispersal of the ectoparasitic mite Varroa destructor (a highly efficient vector of DWV) to reproduction on honey bees (Apis mellifera). Our study examines how varroa affects the continuing evolution of DWV, using the Azores archipelago, where varroa is present on o...
Varroa destructor shapes the unique viral landscapes of the honey bee populatio...
Lopes, Ana Rita; Low, Matthew; Martín-Hernández, Raquel; Miranda, Joachim R. de; Pinto, M. AliceThe worldwide dispersal of the ectoparasitic mite Varroa destructor from its Asian origins has fundamentally transformed the relationship of the honey bee (Apis mellifera) with several of its viruses, via changes in transmission and/or host immunosuppression. The extent to which honey bee-virus relationships change after Varroa invasion is poorly understood for most viruses, in part because there are few places...
Lake Sinai virus in Azorean Honey bees: Understanding the impact of Varroa dest...
Lopes, Ana; Low, Matthew; Martín-Hernández, Raquel; Miranda, Joachim; Pinto, Maria AliceLake Sinai virus (LSV) is a pathogen affecting honey bees worldwide. It was first discovered in 2009 in Lake Sinai, USA, and manifests as a multi-strain virus. The Azores archipelago comprises islands with and without Varroa destructor, offering a unique setting for studying viral epidemiology. Building upon insights from the heterogeneous distribution of Deformed wing virus (DWV) strains, which was modulated b...
