The major histocompatibility complex (MHC) is central for self-/non–self-recognition and acquired immunity. The extreme polymorphism of MHC genes, promoted by parasite-mediated selection, contrasts with limited within-individual diversity. The prevailing explanation is a trade-off between increased pathogen recognition and the anti-autoimmune T cell receptor (TCR) depletion mechanism. However, the predicted inverse relationship between individual MHC diversity [...]

Publication in Journal of Human Evolution on arboreal locomotion in feathertail gliders (Acrobates pygmaeus)

A paper by Leszek Rychlik (Department of Systematic Zoology) and collaborators (from Aristotle University of Thessaloniki) about arboreal locomotion in the feathertail glider (Acrobates pygmaeus) appeared in the Journal of Human Evolution (Q1 in Anthropology). The authors demonstrate a strong preference of A. pygmaeus for small and horizontal substrates, avoidance of large and [...]

Publication in Molecular Ecology

Jacek Radwan, Magdalena Migalska and Alvaro Sebastian, in collaboration with colleagues from Institute of Nature Conservation PASand Lund University, in a paper published in Molecular Ecology, documented selection acting on major histocompatibility complex (MHC) genes in sedge warbler (Acrocephalus schoenobaenus). MHC proteins are crucial in pathogen recognition, it is still poorly under-stood how pathogen-mediated selection promotes and maintains MHC diversity, and especially [...]

Paper in Journal of Mammalogy on the influence of masting on the cross-habitat dispersal of competing rodents in Bieszczady Mts

In the Journal of Mammalogy (Q1 in Zoology), Rafał Zwolak, Michał Bogdziewicz and Leszek Rychlik (Department of Systematic Zoology), and collaborators from the Museum and Institute of Zoology PAS, published a paper on the influence of beech masting on the cross-habitat dispersal (from forests to meadows) of competing rodents in Bieszczady Mts. Authors tested 3 [...]

Article in Journal of Mammalogy on the role of venom in hunting and food hoarding by the Eurasian water shrew

In Journal of Mammalogy (Q1 in Zoology), Krzysztof Kowalski and Leszek Rychlik (Department of Systematic Zoology) published a paper on the role of venom in hunting larger prey and food hoarding by the Eurasian water shrew Neomys fodiens (Soricidae). Authors showed, among others, that N. fodiens required significantly less time than the [...]

Publication in Comparative Biochemistry and Physiology on the properties and composition of the toxins from parotoid glands of the the common toad Bufo bufo

In the journal Comparative Biochemistry and Physiology, Part C (Q1 in Zoology), Krzysztof Kowalski, Leszek Rychlik (Department of Systematic Zoology), and co-authors from the Institute of Experimental Biology, Paweł Marciniak and Grzegorz Rosiński (Department of Animal Physiology and Development) recently published a paper with the new results demonstrating strong cardio- and myotropic properties, and low [...]

One widely accepted fitness advantage of being a masting plant (instead of just producing seeds every year) is the predator satiation. According to this mechanism, masting helps to increase seed survival through starving predators in non-mast years (famine cause the predator population to go decrease in numbers), and sparse predators are easy satiated in mast [...]

Publication in Scientific Reports authored by members of our Institute: T-cell receptor (TCR) repertoire profiling in non-model species using high-throughput sequencing

High-throughput sequencing (HTS) prompted development of novel, refined methods of analyzing immunological repertoires (e.g. immunoglobulins, TCRs). So far, despite a decade of progress, these techniques were mainly used in research involving model species and humans. Recently, Magdalena Migalska, Alvaro Sebastian and Jacek Radwan (Evolutionary Biology Group) published an article in Scientific Reports describing first use of HTS in TCR repertoire sequencing [...]

Publication in Journal of Ecology

New study describing how apparent predation occurring between two sympatric oaks influence their recruitment rates was just published in Journal of Ecology. The Authors (Michał Bogdziewicz, Nathanael Lichti, Rafał Zwolak) wrote a short summary of their work: Numerous plants are dispersed by scatterhoarding animals such as corvids and rodents. These animals carry away and cache [...]

Publication in New Phytologist

The paper by Bogdziewicz et al. on the role of environmental constraints in mast seeding was published in the latest issue of New Phytologist. We wrote about the research in the past post (link). In the same issue, Tanentzap & Monks published a positive commentary on that research.
