Вплив географічних факторів на таксономічне багатство ґрунтової фауни колембол [Impact of geographical factors on the taxonomic richness of soil springtails fauna]
Journal Title: Праці Наукового товариства ім. Шевченка - Year 2016, Vol 46, Issue
Abstract
The study tested impact of such geographic factors as area, latitude, longitude, and altitude on the taxonomic richness of the soil fauna of Collembola applying correlation and ordination analyses. As a result, it was found that species richness of regional collembolan faunas on average can be increased in 1.3 times by increasing the area per 1000 km2. Moreover, moving from south to north on each degree of latitude, the species richness of collembolan fauna reducing in average on 3.7 species, while moving from west to east on each degree of longitude – reducing in average on 3 species. However, this correlation is not linear. The rate of decreasing of Collembola species richness per each degree of latitude at the level of local faunas in the high latitudes is in average 3 times higher than in the low latitudes (macroregional scale). In the micro- and mesoregional scales of study we did not find reliable correlation of species richness with variables of latitude and longitude. Therefore, we suggested that withdecreasing of territorial scale, a larger impact on species richness of local fauna of Collembola represent climatic, edaphic, biotic and historical factors rather than geographical.
