Dispersion of Bumblebee Bombus Semenoviellus Skorikov (Hymenoptera, Apidae) in Poland

Abstract

<jats:title>Abstract</jats:title><jats:p>The aim of the study is to present all distribution sites of <jats:italic>Bombus semenoviellus</jats:italic> in Poland reported between 1988 and 2019. The increase of species dispersion was concluded, especially in the central part of the country, as well as the occurrence in the high Karkonosze and Tatry mountains. This is likely the effect of progressing climate change, as well as the increase in climate continentalism in Europe. Differences between summer and winter temperatures favour the spread of this Siberian bumblebee species throughout the continent. Many specimens were found on plants originating from its central and west Asia. Those plants also occur in eastern and central Europe which could have helped this bumblebee spread west throughout Europe. <jats:italic>B. semenoviellus</jats:italic> will increase its range towards Western Europe. Based on observations so far, it is not possible to determine its invasive features and increased competitiveness for food and nesting places in relation to other bumblebee species.</jats:p>

Effects of Open and Forest Habitats on Distribution and Diversity of Bumblebees (Bombus) in the Małopolska Upland (Southern Poland): Case Study

“…This study conducted in Poland indicates new locations of bumblebees and their dispersal, especially in the southern part of the country. Michołap et al [ 50 ] suggested that the increase of continentalism in Europe could also be likely to affect the current status of bumblebee species expansiveness, while the biodiversity of plants occurring in Central and Eastern Europe may help these species spread throughout Europe.…”
