We showed that in addition to the spatial attributes of woodlots (that is, their area, isolation, and shape), local habitat is an important predictor of woodlot bird species richness. The overall richness of bird species increased with vegetation height and the richness of woody plant species and decreased with the cover of an invasive tree, the Black Locust Robinia pseudoaccacia. On the contrary, the richness of farmland bird species was positively related to the diversity of woodlot microhabitats, which reflects mainly enrichment by non-forest habitats such as grassland or sparse shrubs.

Our results indicate that the current practices implemented by the EU’s CAP subsidy system favour widespread forest bird species, but not the farmland birds that are more threatened in Europe, for which a microhabitat heterogeneity should instead be maximized.

The study was carried out in cooperation with Charles University in Prague, Czech Republic.

In this article, we explain how environmental heterogeneity influences niche breadth evolution, which may in turn affect the ability of pests to persist in agricultural systems.

In this study, dispersal strategies of two phytophagous eriophyoid mite species: Aceria tosichella (wheat curl mite, WCM) and Abacarus hystrix (cereal rust mite, CRM) were investigated. We estimated their dispersal success using different dispersal agents: wind and vectors. Results showed that both species dispersed mainly with wind currents whereas phoretic dispersal was rather accidental, as the majority of eriophyoid mite species do not possess clear morphological or behavioural adaptations for phoresy. Additionally, WCM was found to have a higher dispersal success than CRM. Thus, this study contributes to our understanding of the high invasive potential of WCM.

How can species persist when their habitat disappears? Theoretically, in seasonal environments, habitat sinks (where population growth is zero or negative) could serve as temporal stepping-stones (refuges) for specialists, but this possibility has not been demonstrated to date. By combining laboratory experiments and field surveys, we demonstrated the importance of sink habitats for population persistence in temporally varying environments. Together, our results emphasize the relevance of source-sink dynamics in shaping species’ ecological niches. They also have significant implications for explaining patterns of host use by specialists, and the persistence of agricultural pests when their preferred host plants are absent.

A recent paper, co-authored by Wiktoria Szydło, reported the full genomes of two European Wheat streak mosaic virus isolates, provided their molecular and biological characteristics and transmissibility by wheat curl mite (lineage MT-8), the only known vector of the virus. Although widely present in Europe, the virus transmissibility was formally checked for the first time with a local population of mites and local virus isolates. The study of genetic diversity of the WSMV populations and the occurrence of recombination events within the virus population should be considered in future disease management strategies, as well as local virus isolates should be incorporated into studies on the virus-vector relationship.

A new paper, co-authored by Lechosław Kuczyński from our Lab, was published in Limnology and Oceanography. The authors investigated thermal adaptation of Daphnia from lakes that had been artificially warmed for six decades and served as a whole ecosystem model of future temperature increase. Daphnia from heated lakes evolved larger body size, which is contradictory to general expectations and theory. Authors suggest that large size is adaptive during warmer and iceless winters when daphnids overwinter in active form.

In our recent paper we evaluated temperature-dependent development and survival of an invasive wheat curl mite Aceria tosichella at a wide range of temperatures. The results allow for predicting and monitoring the mite population growth rate. They also provide information promoting more efficient and effective manipulation of mite laboratory colonies and testing a wide array of ecological and evolutionary hypotheses.
