The 4th Marcin Antczak Award for the most inspiring ornithological paper published in 2017 goes to Jakub Szymkowiak from our Lab!
The Award commemorates Marcin Antczak, who was an excellent field ornithologist, but also our good friend. He tragically died in car accident on his way to the field on 2nd May 2014, in his 37th year of life.
Our recent paper published in Bird Conservation International is the first attempt to estimate the size of the Polish breeding population of the highly vulnerable farmland raptor: the Montagu’s Harrier. By combining multiple sources of data we estimated the Polish Montagu’s Harrier population at almost 3,400 breeding pairs, thus constituting 20% of the European Union population. Furthermore, we showed that public-gathered data obtained by volunteer-based citizen-science projects offer great potential for regular surveys to obtain large-scale estimates of population size.
The paper is part of Natalia’s PhD thesis. Congratulations!

The article about genetic and host differentiation within the complex of phytophagous species belonging to Abacarus genus, authored by members of our Lab, was published in Experimental and Applied Acarology. The molecular analyses indicate that there may be at least several new species within the complex, that are awaiting formal description. One of them, Abacarus plumiger inhabiting smooth brome, has been described in this article.

An article co-authored by Anna Skoracka, Lechosław Kuczyński, Agnieszka Majer and Wiktoria Szydło, about the genetic structure within species complex of phytophagous mite, Aceria tosichella, was published in BMC Evolutionary Biology.
Mites belonging to the complex Aceria tosichella (wheat curl mite, WCM) are major pests of the world’s grain industry and our aim was to identify the factors behind its extensive diversification. We demonstrated unusually deep lineage diversification within the taxon. Using time-calibrated phylogenetic reconstruction we showed that lineage diversification pre-dates the influence of agricultural practices, and lineages started to radiate in the mid‑Miocene when major radiation of C4 grasses is known to have occurred. Furthermore, we showed that host generalization coincided with the expansion of the world’s grasslands in Pliocene. The genetic structure and evolutionary history of WCM lineages indicate their great colonization potential.

Review papers, co-authored by Anna Skoracka, about relationships between the mite Aceria tosichella, its main host: wheat, and the viruses that the mite transmits were published in Molecular Plant Pathology and Frontiers in Plant Science
The mite Aceria tosichella (wheat curl mite, WCM) in the interaction with the virus causes considerable yield losses worldwide. The challenge of effectively managing this pest-virus complex is exacerbated by the existence of divergent WCM lineages that differ in host colonization and virus transmission abilities. In these publications, there is highlighted research progress in mite ecology and virus epidemiology that affects management and development of cereal cultivars with WCM- and virus-resistance genes. The potential application of molecular methods (e.g., transcriptomics, epigenetics, and whole-genome sequencing) are proposed to understand the chemical and cellular interface between the wheat plant and WCM-viruses complexes.
The publications were prepared in cooperation with the University of Nebraska-Lincoln, USA and Crop Research Institute, Czech Republic.

An article, co-authored by Lechosław Kuczyński, was published in the latest issue of Journal of Evolutionary Biology.
Using data collected in a secondary contact zone of two hybridizing songbirds: the Common Nightingale (Luscinia megarhynchos) and the Thrush Nightingale (Luscinia luscinia), we looked for associations between habitat use and bill morphology. In line with our previous results (https://doi.org/10.1111/1365-2656.12808), we found that the two nightingale species differ in habitat use in allotopic but not in syntopic sites. Moreover, birds from allotopic sites showed higher interspecific divergence in relative bill size compared to birds from syntopic sites. Our results are consistent with the view that interspecific competition in nightingales has resulted in partial habitat segregation in sympatry and that the habitat‐specific food supply has in turn very likely led to bill size divergence.
The study was done in cooperation with the Charles University in Prague, Czech Republic.
