AB  - Deep phylogeographic structure in mitochondrial DNA not reflected in morphological variation has been uncovered in a number of species over the past few decades. However, inferred phylogeographic structure based solely on mitochondrial DNA can be misleading and might not reflect the true history of evolutionary lineages. Consequently, such cases should be further investigated based on genome-wide data. One of these examples is provided by the Middle Spotted Woodpecker Dendrocoptes medius, a non-migratory habitat specialist associated with old deciduous forests of the Western Palaearctic. It displays strong genetic divergence in mitochondrial DNA between Asian and European populations despite there being only slight variation in morphology between them. Here, we found a clear genomic divergence between Asian and European populations that is consistent with mitochondrial divergence patterns. As revealed by isolation by distance analyses, this differentiation in two lineages was not merely an effect of geography. Genomic population structure indicates that both the Asian and European lineages might each have been separated in more than one refugium during the last glacial maximum. The Middle Spotted Woodpecker might represent a case of cryptic diversity throughout its distribution range, as has been previously found for other taxa across the tree of life. However, we also found footprints of gene flow from the Asian into the European populations, suggesting at least limited introgression upon secondary contact. The processes and mechanisms that might prevent lineage fusion between the morphologically cryptic but genetically divergent lineages of the Middle Spotted Woodpecker need to be further investigated especially in the area of potential secondary contact.

AB  - Hewitt’s paradigm for effects of Pleistocene glaciations on European
populations assumes their isolation in peninsular refugia during glacial
maxima, followed by re-colonization of broader Europe during interstadials.
This paradigm is well supported by studies of poorly dispersing taxa, but
highly dispersive birds have not been included. To test this paradigm, we
use the dunnock (Prunella modularis), a Western Palaearctic endemic whose
range includes all major European refugia. MtDNA gene tree, multilocus
species tree and species delimitation analyses indicate the presence of three
distinct lineages: one in the Iberian refugium, one in the Caucasus refugium,
and one comprising the Italian and Balkan refugia and broader Europe. Our
gene flow analysis suggests isolation of both the Iberian and Caucasus
lineages but extensive exchange between Italy, the Balkans and broader
Europe. Demographic stability could not be rejected for any refugial population, except the very recent expansion in the Caucasus. By contrast,
northern European populations may have experienced two expansion
periods. Iberia and Caucasus had much smaller historical populations than
other populations. Although our results support the paradigm, in general,
they also suggest that in highly dispersive taxa, isolation of neighbouring
refugia was incomplete, resulting in large super-refugial populations.

AB  - Deforestation, urban development, and global climate change can lead to dramatic changes of ecological communities and increase
prevalence of infectious diseases at higher latitudes and altitudes. Identification of factors responsible for the prevalence of parasites is
of crucial importance to understand the dynamics of parasite distribution in a changing environment. Mountain areas are especially
suitable for studies of factors governing parasite distribution and prevalence due to heterogeneity of landscapes, climatic regimes, and
other biotic and abiotic conditions.We examined 903 avian blood smears collected in mountains of Transcaucasia for prevalence of
Haemoproteus and Plasmodium.We found that the haemoparasites prevalence differed among bird species and localities, highlighting
the environmental components affecting disease distribution. The prevalence of both Haemoproteus and Plasmodium was
significantly higher in males, adults, and migratory species than in females, juveniles, and resident species. Geographic
Information System (GIS) and linear regression analyses revealed that elevation and monthly average precipitation were strongly
correlated with proportion of infected birds with Plasmodium, indicating that the prevalence increased with increase of monthly
average temperature and elevation. Birds from forested and high grassed areas were also more infected with avian haemosporidia.
Our study provides baseline data for modelling of parasites distribution under global climate change scenarios, which is of great
importance for monitoring and management of communities and environment for conservation and human health.
