description | One third of species of Eastern Ukraine’s
mayfly fauna develop in coldwater watercourses of Donetsk
Elevated Area. Ten species develop in rhithral streams of
area and only two in crenal ones. A number of species are
presented in area by the populations isolated from main
parts of them areals (Alainites muticus, Serratella ignita).
Areal of Ecdyonurus dispar gratificus is limited by the
area under investigation, where the larvae of this species
inhabit pure rhithral watercourses mainly. Larvae of the
species which inhabit rhithral zone of region’s streams,
are attributed to four types of ecomorphs and take part in
formation of different types of the communities. Larvae of
each species demonstrate their own stational preferences,
which depend on their ecomorphological characteristics.
Quantitative ratio of mayflies’ larvae of different species
and their types of ecomorphs change considerably during
the year. Competition between the species which prefer the
same microstations is reduced due to displaced life cycles.
In the result, the maximums of biomass and population size
of these species are almost never observed simultaneously.
Considering that the anthropogenic changes and pollution
of rhithral zone of model watercourses is almost absent,
their mayfly species composition, the change of quantitative
ratio of different species’ larvae during a year, the features
of stational distribution and the structure of communities
could be considered as model ones in indicative researches
on the rhithral zone of Donetsk Elevated area |
