Monitoring climate changes and habitat degradation in threatened species without negative impact to the populations can pose a considerable challenge. A rare chance to test the morphological response of wing shape and size to environmental factors on the mountain Apollo (Parnassius apollo) collected from 1938 to 1968 at a single location – Strečno mountain pass, N Slovakia presented itself in a historical collection. The canonical variate analysis showed a significant shift from a narrower to broader forewing, with more extremes in either extra broad or narrow forewings in the post- 1960 population. Analysis of existing data was conducted to determine the possible factors affecting this change. Generally, the comparative statistics of temperature and precipitation to morphology of individuals and their fluctuating asymmetry showed no, or weak, correlations. Two extreme weather events (ECEs), identified using the historical weather data, show no correlation of wing morphology to these events. Although no strong correlations can be drawn in case of the available weather data and morphology, the results of this study can be connected to strong anthropogenic effects of a large-scale road development project taking place in the vicinity of the collection site starting in November 1959 causing changes in the available habitat and therefore a shift in the wing morphology.

(2017): First record of a new alien economically important thrips Dichromothrips corbetti (Priesner, 1936) (Thysanoptera: Thripidae) in Slovakia -short communication. Plant Protect. Sci., 53: 177-180.The first record of vanda thrips (Dichromothrips corbetti [Priesner, 1936], Thysanoptera, Thripidae) in Slovakia is presented. An economically important pest with heavy infestations on flowers of Phalaenopsis orchids was recorded as introduced most probably from North African plantations. Potential infiltration of this exotic species into Central European glasshouses refers to the globalisation of trade in biological commodities.

After the first record of the banded greenhouse thrips, Hercinothrips femoralis (Reuter, 1891) in Slovakia in 2008, a peculiar occurrence in an extreme subalpine environment of Podbanské (High Tatra Mts.), Slovakia, during the summer of the same year was observed. Since this species of exotic thrips is known to be almost sedentary, the mode of dispersal was hypothesized to be related to passive transport via weather currents. According to our observations of unintentional dispersal a test was conducted to research a previously unidentified introduction pathway of this species. Our preliminary results show that passive transport by humans plays a crucial role in the dispersal of H. femoralis.
