Abstract
An important step in research planning is the choice of methodology. This is especially important for territories which are difficult to access such as in the Arctic, where successive repetitions of field works require significant resources. The methodology utilizing the local fauna has been used over the past twenty years. It provides comparable data on the structure of fauna and species richness for different territories. The purpose of the present study was to assess the “local fauna method” with respect to fauna studies of ground beetles in the Arctic forest-tundra zone. The research was conducted from June 18 2017 to August 30 2017 within the Polar Urals (10 km from the Harp settlement in the Yamalo-Nenets Autonomous Okrug, which is a state of Russia). Carabids were sampled by using pitfall traps on 20 sites. This article will also include the results of our previous research concerning the structure of some local faunas from the forest-tundra zone of Nenets Autonomous Okrug (settlements Nes’, Oma, Khorey-Ver). The results of this study demonstrate the following: 1) the local fauna of the Polar Urals has 85 species of ground beetles from 25 genera, which is 77% of species lists of carabids for a 70-year period of research within the Polar Urals; 2) the local fauna of the Polar Urals has 29% similarity of list species with local faunas from the European part of the Arctic, with similar compositions of zoogeographical groups and life forms; 3) in one research period there was 90% detection of carabids species in the forest-tundra local fauna using the sampling method of pitfall traps within a period of 40 days, conducted at 15 sites, with the predominance of southern types of plant communities (meadows, forests).
Highlights
Studies of ground beetle faunas (Coleoptera, Carabidae) in the Polar Urals have been systematically conducted over the last 60 years (Stebaev 1959, Olshvang 1980, Korobeinikov 1984, Zinovyev and Olshvang 2003, Uzhakina and Dolgin 2007)
The greatest presence was exemplified by Palearctic species - 56.5%; the Northern Holarctic faunal type accounted for 31.8%; the Euro-Siberian faunal type accounted for 8.2%; and the European faunal type accounted for 3.5%
The aforementioned “local fauna method” was used, and to our knowledge this was the first time, in the forest-tundra of the Polar Urals and within one vegetation season this allowed the collecting of 77% of the regional carabid fauna
Summary
Studies of ground beetle faunas (Coleoptera, Carabidae) in the Polar Urals have been systematically conducted over the last 60 years (Stebaev 1959, Olshvang 1980, Korobeinikov 1984, Zinovyev and Olshvang 2003, Uzhakina and Dolgin 2007). Using the local fauna approach it is possible to obtain comparable data on species richness and fauna structures of soil invertebrates with the determination of the maximum species compositions for a certain territory. This method was used for studying ground beetle local fauna of semi-deserts in the Volga Region (Makarov and Matalin 2009) and the European sector of the Russian Arctic (Filippov and Shuvalov 2005, Filippov 2008, Markov 2011, Zubriy and Filippov 2015). The main aim of the present research was to study the ground beetle local fauna of the Polar Urals forest-tundra zone and to estimate the effectiveness of species richness determination
