The present paper includes the results of a year-round pitfall trapping survey of ground beetles in the region of Lake Elton, Volgograd Area, Russia. The main objectives of the project lie in studying the local fauna of
This is the first sampling-event dataset of a year-round pitfall trapping survey (from May 2006 until May 2007) of ground-beetle communities and the demographic structure of local populations of particular species in the Lake Elton region, Volgograd Area, Russia.
The fauna of ground beetles (
Pitfall traps were set in ten model habitats: six zonal, characteristic of this particular biogeographic area and four azonal, present in a variety of biogeographic areas.

The demographic structure of the local populations of particular ground beetle species was studied in ten model habitats described above. Plastic pitfall traps of 0.5 l capacity and 95 mm upper diameter containing 4% formalin as a fixative were used. In each habitat, ten traps were arranged along a transect at 10 m intervals. Due to the high daily air temperature and low air humidity, the fixative content was increased to 3/4 of the trap’s volume. The traps were set from 10 May 2006 until 10 May 2007 and were checked at 10-day intervals on the 10th, 20th and 30th(31st) day of each month with the exception of the period with negative temperatures, from 1 November 2006 until 31 March 2007 (
Based on gonad condition, as well as on the degree of wear-and-tear of the mandibles, claws and cuticle, six physiological states were distinguished in the adults of both sexes: teneral, immature, mature of the parental and ancestral generations and spent of the parental and ancestral generations (
The life cycle of particular species was reconstructed according to the chorological series in each local population. In ‘spring breeders’, such chronological series are represented by: immature of parental generation after hibernation → mature of parental generation → spent of the parental generation → teneral of a new generation → immature of the new generation prior to hibernation (Figure 1 in

We sampled carabids from 10 May 2006 until 10 May 2007, checking the traps at 10-day intervals, with the exception of the period with negative temperatures.
