Composition and structure of island communities
is one of the main problems in ecological science
(Chernov, 2008). Island taxa of bumblebees are char
acterized by a number of specific features (Bolotov
et al., 2013). The structure of bumblebee communities
on the Russian islands has not been studied suffi
ciently. There are data on the bumblebee fauna of the
Solovetsky Islands (Bolotov et al., 2013), as well as of
Kolguyev (Kolosova and Potapov, 2011) and Wrangel
(Berezin, 1992) islands.
The aim of this work is to analyze the structure and
species diversity of bumblebee taxocenes in some eco
system types of Kunashir Island and Southern Sakha
lin. There are no publications covering this issue,
despite that the bumblebee fauna on the islands of the
Russian Far East has been studied in detail (Sakagami
and Ishikawa, 1969; Krivolutskaya, 1973; Ito and Sak
agami, 1980; Lelej and Kupianskaya, 2000; Prosh
chalykin, 2003; Proshchalykin et al., 2004, 2012).
What is more, the abundance of certain bumblebee
species has been approximately estimated (Krivo
lutskaya, 1973; Ito and Sakagami, 1980), and trends in
the distribution of bumblebees on the islands (Ito and
Sakagami, 1980; Lelej and Kupianskaya, 2000) and
their trophic relationships (Lelej and Kupianskaya,
2000) have been considered.
MATERIAL AND METHODS
The study was performed in July 14–27, 2011 in
the course of the complex expedition to Sakhalin and
Kunashir for the purposes of federal research projects.
One of them was to estimate the state of certain com
ponents in geothermal and zonal island ecosystems.
Bumblebees were sampled in five habitat types
(Table 1). Sample size varied from 114 to 304 bumble
bees (a total of 841 ind.). In addition, 65 ind. were col
lected on Kunashir Island in tall grass meadows at the
Stolbovskie hot springs (
This sample was not used for statistical calculations
because of its small size.
Plant species were identified using the keys by
Voroshilov (1982) and Alekseeva (1983). Bumblebee
species were identified in the basis of tables by Kupy
anskaya (1995) and Japanese researchers (Sakagami
and Ishikawa, 1969; Ito and Sakagami, 1980).
Subgeneric and species taxonomy of bumblebees is
mainly given according to the catalogs of the world
fauna (Williams, 2012), except for that of
. Williams (2012) considers that these
are not true species but rather island races of wide
B. (Megabombus) consobrinus
B. (Bombus) cryptarum
(Fabricius, 1775), respec
tively. Nevertheless, we regard
as separate species, and this opinion is shared
by many taxonomists (Ito and Sakagami, 1980; Lelej
and Kupianskaya, 2000; Proshchalykin, 2003; Prosh
chalykin et al., 2004, 2012).
The relative abundance of bumblebees was esti
mated based on the proportion (%) of corresponding
individuals in the samples (Pesenko, 1982). In order to
estimate the species diversity, Shannon’s index (based
on the natural logarithm) and Berger–Parker domi
nance index were used (Magurran, 1992). Parameters

—The structure of bumblebee communities has been studied in some ecosystems of Kunashir Island
and Southern Sakhalin. The island taxocenes include five to eight bumblebee species.

species develop more rapidly than in areas without geothermal heating.
