Climate change continues to reshape our natural ecosystems, and its impact on tree populations is a topic of great concern. Recent study (link: https://onlinelibrary.wiley.com/doi/full/10.1111/gcb.16730) led by Michal Bogdziewicz investigating the response of European beech (Fagus sylvatica) to climate warming has uncovered intriguing insights into the complex relationship between tree reproduction, climate change, and forest dynamics.

In a recent paper (link) Jon Parrett and co-authors from our Institute and Ghent University provided genomic evidence from mites with sexually selected weapon  that this costly trait captures genome-wide variation and facilitates the purging of genetic load from populations.

Leszek Rychlik and co-authors (mainly from the University of Lisbon, Portugal) tested average differences in behaviour as well as the inter-individual variation in behaviour in rural and urban populations of shrews belonging to two species differing in life history and time since synurbanization: the fast-paced Sorex araneus and the slow-paced Crocidura russula. As predicted, [...]

Leszek Rychlik and co-authors from Portugal assessed the use of an external heat source (basking) in the thermoregulatory strategies of three shrew species. Shrews were tested in a terrarium where they had access to a heat rock which could be turned off (cold) or on (heated). In accordance with authors' predictions, Crocidura russula (the [...]

High polymorphism of major histocompatibility complex (MHC) genes that encode proteins crucial for adaptive immunity of vertebrates have been long hypothesized to be maintained by negative frequency-dependent selection resulting from adaptation of parasites to common MHC types, but supporting evidence is scarce. In our new paper in Molecular Ecology (Migalska et al. 2022, http://doi.org/10.1111/mec.16486) we find [...]

In the article published in Proceedings of the Royal Society B, https://doi.org/10.1098/rspb.2022.0212 dr Magdalena Herdegen-Radwan (Department of Behavioural Ecology) presents empirical suport for the role of associative learning in originating sexual preferences. Sexual preferences of guppy females changed following food-conditoning on different colours, supporting the emergence of an association between the colour of the stimulus [...]
