In the leafhoppers of the genus Aphrodes are mate recognition and location of the female based exclusively on highly divergent male advertisement calls and similar female replies. Male calls composed of similar elements played only a limited role in mate recognition. In a species pair in which females responded well to each other’s male calls, the generally higher responsiveness of A. aestuarina females to male calls of A. bicincta did not translate into higher mating success in this heterospecific cross.

Reliable delimitation and identification of species is central not only to systematics, but also to studies of biodiversity, ecology and pest management. We studied Aphrodes individuals collected from the U.K. and Slovenia in order to provide a more comprehensive analysis of this genus using multiple criteria. The results of the study showed that combined behavioural, morphological and molecular approaches are very valuable for distinguishing taxonomically challenging groups of insects, such as genus Aphrodes.

The Ural Owl lost much of its distribution in Europe. To date, no genetic information has been available for ongoing conservation and breeding programmes. Genetic analyses intend to deliver data for establishing sustainable management strategies. Mitochondrial and nuclear markers were used to evaluate the morphologically based concept of two subspecies (Strix u. liturata and Strix u. macroura).

Food consumption rate, respiration rates in the air and water, the difference between energy consumption and respiration costs at a given temperature and intensity of electron transport sysem activity (ETS) of Orconectes limosus and Pacifastacus leniusculus were determined over a temperature range of 5 – 30 °C. The significant correlation between ETS activity and PGS indicates that they respond similarly to temperature change.

This chapter describes vibratory communication of stink bugs, emphasising advantages and disadvantages of their choice to use narrow-frequency channel. The vibratory signals are characterised by dominant component around 100 Hz, a different number of higher harmonics generally not exceeding 1,000 Hz and different degrees of frequency modulation, and are tuned with plants as their main communication media.
