Results of Long-Term Monitoring of the Genus Carabus (Coleoptera: Carabidae) in the Barguzinsky Range (Northern Baikal Region)

A study of the long-term abundance of ground beetles of the genus Carabus over a 30-year period has been made. The ratios of climatic factors that have a corrective effect on the level of their numbers are established. The level of precipitation, the duration of the frost-free period, and the ground temperature on the soil surface are the most important meteorological parameters in the life of genus Carabus. Air temperature affects it through the duration of the biological summer, indirectly limited by the timing of the onset of spring and autumn. The gradation cycles of long-term series determined by intrapopulation and climatic processes are determined. It consists of short (2–4 summers) and long (7–10 summers) periods. Within the framework of phase portraits, the mechanism of action of regulatory factors on the process of numbers long-term dynamics are considered. Stable and prodromal types of the number dynamics of long-term series are established. Fluctuations in the abundance of ground beetles of the genus Carabus did not go beyond the framework of the stationary process during the studied period.
