Abstract
Aims: Integrating ecological niche models (ENMs) into phylogeographic studies, enables identifying the evolutionary processes and can be used to confirm species delimitation, particularly in species complex. The current study examined the divergence of two lineages of Eurasian green woodpecker complex (Picus viridis and P. innominatus), which were recently genetically proposed to the species level, using ecological niche modeling (ENM).
Materials & Methods: The ENMs were built using 1346 occurrence points, and environmental layers including 19 bioclimatic variables as well as elevation and land cover for past and present timescales. Niche identity, background tests and principal component analyses (PCA) were then performed to compare their ecological niches and explain ecological differentiation.
Findings: Results of identity and background tests and PCA revealed the lineages occupy unique and distinctive niches, and supported recently proposed genetically distinct species. Regarding the environmental variables, PCA results revealed that precipitation has a more important role in the separation of P. viridis and P. innominatus.
Conclusion: This study, in addition to provide an ecological support for recent molecular classifications, revealed niche conservatism had a more important role in the evolution of the two lineages of Eurasian green woodpecker complex.

Abstract
Based on all collected literature dealing with the fauna of springtails in Vojvodina Province (Republic of Serbia), a list of species was created and taxonomically revised according to the latest system of Collembola taxonomy. In total, the check list of springtails of Vojvodina includes 125 species in 58 genera from 16 families and 3 orders. The most abundant order is Entomobryomorpha (55%), followed by Poduromorpha (24%) and Symphypleona (21%). According to the general distribution of the species themselves, the presented list has the following composition: 27.2% of the recorded species are European, the same number are Palearctic, 24% of the species on the list are Holarctic, 18.4% are cosmopolitan, and 3.2% are endemic to Serbia (mostly related to type localities). The species Drepanura deliblatica Loksa & Bogojević, 1970, Sinella jugoslavica Loksa & Bogojević, 1970, Deuterosminthurus quadrangulatus (Loksa & Bogojevic, 1970) and Fasciosminthurus angulipunctatus (Loksa & Bogojevic, 1970) are strictly protected species in the Republic of Serbia. This paper is a contribution to the knowledge of the Collembola fauna of Europe and represents a step towards the formation of a checklist of springtails of the Republic of Serbia.
