| Summary: | Based on the collected data set (758 observations for the period 2007-2021) on the dates of the
nuptial flight for 73 species of ants, an analysis of possible time shifts due to global climate
changes has been carried out. It was found that for Eastern Europe and Asia, for most species
of ants, the dates of nuptial flight were shifted by at least two weeks earlier in comparison with
the data for Western Europe. In a cold climate, there are significant changes, towards earlier
dates, in the phenology of nuptial flight for two species: Lasius flavus (P<0.05) and Polyergus
rufescens (P<0.01). The corresponding rates of change are 3.9 and 6.25 days per year. In other
types of climate, no significant changes in the phenology of the nuptial flight were found.
Taking into account the boundaries of future climatic zones in temperate and arid zones, such
changes were recorded for several species. Solenopsis fugax in temperate climates shows a
tendency to delay flight at a rate of 6 days per year (P<0.05). Within the predicted boundaries
of the arid climate, the flight phenology delay was recorded for Lasius niger (5.8 days per year;
P<0.01) and Messor sp. (4.4 days per year; P<0.05). At the same time, for Polyergus rufescens,
there is a tendency to an earlier flight at a rate of eight days per year (P<0.05). No connection
was found between the date of nuptial flight and the geographic distance between populations
(or locations). |
