Timing of reproduction in birds is important for reproductive success and is known to depend on environmental cues such as day length and food availability. However, in equatorial regions, where day length is nearly constant, other factors such as rainfall and temperature are thought to determine timing of reproduction. Rainfall can vary at small spatial and temporal scales, providing a highly ...

The essential root oils of the Pimpinella saxifraga subspecies eusaxifraga, alpestris and nigra were investigated by means of capillary GC and spectroscopic methods. A total of 48 components was identified. Characteristic constituents of all oils are pseudoisoeugenol derivatives, sesquiterpenoids and trinor-sesquiterpene hydrocarbons, but the qualitative and quantitative patterns of the individ...

A comparative analysis of the habitats of Baldellia ranunculoides (subsp. ranunculoides and subsp. repens) and Baldellia alpestris (Alismataceae) was carried out across central and western Europe. Soil samples from 43 populations were analyzed and the composition of accompanying vegetation was analyzed by canonical correspondence and indicator species analysis. Significant differences in the ha...

The phylogeography and molecular taxonomy of the Alpine newt, Ichthyosaura alpestris, has been intensively studied in past. However, previous studies did not include a comprehensive sampling from Carpathian Basin, possibly key region evolution species. We used 1251 bp long fragment mitochondrial genome to infer species’ evolutionary history central-eastern Europe by assigning isolated Basin pop...

Abstract Theory suggests that spatial segregation of similar, co-occurring species may be driven by alternative innate life history and dispersal strategies, it operates through catastrophic events. An inventory the evolutionary closely related small-bodied newts Lissotriton helveticus L. vulgaris in northwest France demonstrated species’ partitioning, with dominating two pond-rich historically...
