A tribute to Claude Shannon (1916-2001) and a plea for more rigorous use of species richness, species diversity and the 'Shannon-Wiener' Index
In the literature, the terms species richness and species diversity are sometimes used interchangeably. We suggest that at the very least, authors should define what they mean by either term. Of the…

A relatively simple ANN architecture enabled a 97% correct simultaneous identification of both males and females of all the 18 species in an independent test, which is promising for a wider application of ANN in the practice of Thysanoptera identification.
Physical attractiveness influences reproductive success of modern men
Examination of associations between men’s reproductive success and physical attractiveness from retrospective data obtained from married, divorced, and single samples of Slovakian men found that facially more attractive and taller men were more likely to engage in marriage.
Health Is Associated With Antiparasite Behavior and Fear of Disease-Relevant Animals in Humans
The results support the idea that disgust and fear of disease-relevant objects are adaptive emotions that prevent contact with contagious objects, especially in individuals with low perceived health.
Paternity cues and mating opportunities: what makes fathers good?
Human males provide facultative paternal investment to their offspring; that is, the male care is not necessary for the survival of his offspring. It is expected that the degree of male investment…
An updated identification key to the pseudoscorpions (Arachnida: Pseudoscorpiones) of the Czech Republic and Slovakia
An illustrated dichotomous key is provided for the identification of adults of the pseudoscorpion species found in the Czech Republic and Slovakia, based on morphological and morphometric characters.…
Cues of pregnancy decrease female physical attractiveness for males
The results suggest that putatively pregnant females are less attractive due to the costs of selecting an infertile partner, or due to male unwillingness to invest in biologically unrelated children.
The Thrips (Thysanoptera) of Slovakia
The contribution presents the first national check-list of thrips (Insecta: Thysanoptera) of Slovakia accompanied with ecological and zoogeographical characteristics.
Thrips (Thysanoptera) in nests of the tree sparrow, Passer montanus (L.)
As part of the ornithological research on the breeding biology of the tree sparrow (Passer montanus) in the Jurský sur National Nature Reserve (SW Slovakia), many specimens of the nidicolous fauna…
The most northern record of the alien composite thrips Microcephalothrips abdominalis in Europe – short communication
The climate change induced introduction in synergy with biological commodity trade globalisation may support the ability of exotic elements to establish adequate populations with suitable fitness in mild climate ecosystems dispersing from artificially heated interiors.
