In Poland, Anoplotrupes stercorosus (Scriba) and Trypocopris vernalis (L.), are very common throughout the whole country and belong to the most numerous representatives of the Geotrupidae family. Research on the habitat selectivity of Anoplotrupes stercorosus (Scriba) and Trypocopris vernalis (L.) was conducted in the years 2004-2006 in the Wipsowo Forest Inspectorate (Regional Forest Department in Olsztyn). The dung beetles were collected using Barber traps installed in a clearcut comprising, 2, 3, 5, 8, and 16 year old thickets and tree-stands aged 30, 45, 60, 80, 100 and 135 years. According to phytosociology these tree-stands are a plant community of fresh continental pine forest (Peucedano-Pinetum), while typologically all sites are within the fresh coniferous forest. During the course of this research 29197 individual dung beetles were captured, including 23137 individuals of A. stercorosus and 6060 individuals of T. vernalis. Both species were caught at each research site. At nearly all sites A. stercorosus dominated. Only within the clearcut area were the number of T. vernalis was higher than at other sites. Very many individuals of T. vernalis were present in the clearcut area but their numbers decreased gradually with increasing tree-stand age. An opposite situation was noted for A. stercorosus. There was an interesting statistically-significant decrease in the abundance of both species in the middle-aged tree-stands - 30, 45 and 60-year-old. Analysing the seasonal dynamics revealed one peak in the population of T. vernalis in July, whereas there were two peaks in the population of A. stercorosus: a small peak in July and a much larger peak in September. There was a significant negative correlation between the numbers of T. vernalis and tree-stand age (p<0.05, r =-0.57), and a significant positive correlation between the A. stercorosus population size and tree-stand age (p<0.05, r = 0.48)


Dung beetles (Coleoptera: Geotrupidae) are an extremely important element of many ecosystems. Their activity allows the incorporation of mineral compounds trapped in faeces into the nutrient cycle. Seasonality and habitat preferences are the most important factors shaping the beetle communities inhabiting dung. The present study compares beetle communities inhabiting moose dung Alces alces L. in various forest ecosystems quantitatively and qualitatively. Due to the beetle seasonality, field work was performed from the beginning of March until the end of October 2017 in three habitats: coniferous forest, oak-hornbeam forest and alder forest. The dung beetles were collected using three Barber traps on each site baited with moose dung (80 g ± 10 g) and the traps were emptied as well as rebaited every 15 days. Altogether, 2330 specimen of dung beetles representing three species were collected: Anoplotrupes stercorosus (2088), Trypocopris vernalis (154) and Geotrupes stercorarius (88). These three species were found in all of the studied habitats. The largest total number of individuals was captured in the alder forest (1132 individuals), followed by the broadleaved forest (712) and the smallest number was captured in the coniferous forest (486). In terms of individuals caught, each species was statistically significantly different between the habitats. The largest number of A. stercorosus was captured in the alder forest, followed by the broadleaved forest and the smallest number was caught in the coniferous forest. however, the reverse was observed in the case of T. vernalis and G. stercorarius, where the most individuals were caught in the coniferous forest, and fewer in the broadleaved and alder forests. This is most likely due to the various habitat preferences of each individual species. Furthermore, the seasonal dynamics of this beetle family showed some differences between habitats. These differences most probably resulted from different microclimatic and humidity conditions.
