| Summary: | Thirty-eight grasshopper species were
showed for environs of the Dosang station (Astrakhan
Region, Russia), 22 species inhabit sand desert, 29 species
inhabit the valley of Volga and Akhtuba Rivers. Features
of their phenology, habitat preference and acoustic
communication were investigated. Features of separation
of ecological niches and factors determining reproductive
isolation of grasshoppers were analyzed. It is shown that
species inhabiting the same biotope could have overlap
of food and microhabitat niches, but they have different
acoustic niches. In some cases, interspecific competition
for the acoustic dimension of the biotope is an important
factor limiting biotopical distribution of grasshoppers.
At the same time grasshoppers occupy part of potential
acoustic niches only in all of the studied biotopes. Thus the
acoustic dimension of the biotope is unfilled. It is shown that
the phenology and habitat preferences play an important
role in the reproductive isolation of grasshoppers having
the same or overlapping acoustic niches |
