In this study, we describe an inexpensive and rapid method of using video analysis and identity tracking to measure the effects of tag weight on insect movement. In a laboratory experiment, we assessed the tag weight and associated context-dependent effects on movement, choosing temperature as a factor known to affect insect movement and behavior....

In the period 2012–2015, an extensive mapping of the distribution of the Orthoptera in five regions of the Czech Republic (Jihočeský, Karlovarský, Středočeský, Vysočina and Ústecký regions) was carried out. The selected regions cover 43 % of the Czech Republic. The mapping unit used was a standardized square map of the grid mapping, in which the ha...

Tracking animals using transmitters is a busy research branch in zoology. In this paper, we study the effect of a temperature and transmitter’s weight on a field cricket’s movement. We recorded the movement of 180 field crickets with a 4K camera and the captured movies were analyzed by a novel tracking algorithm based on a soft-computing technique...

We introduce a problem of tracking small animals, especially insects. To solve this problem, we focus on visual tracking in recorded movies, propose our pattern tracking mechanism based on F-transform, and implement a user-friendly software to handle the movies. The tracking core is compared with five state-of-the-art tracking algorithms: KCF, MIL,...

Inundation zones of rivers are risky environments for terrestrial animals because of the regular or irregular occurrence of floods. Although animals in these zones have evolved several strategies to survive floods, behavioural anti‐flooding strategies have seldom been studied but could play an important role in their life history strategies. We pre...

For ectothermic animals, selection of a suitable microhabitat is affected by a combination of abiotic and biotic factors. Also important is the trade-off between those microhabitats with optimal microclimatic conditions and food availability vs. those with the lowest level of competition and lowest risk of predation. Central European species of gro...

According to a study of type specimens of Discotettix adenanii Mahmood, Idris & Salmah, 2007 and copious specimens of D. belzebuth (Serville, 1838) collected in different parts of Borneo, we found that all species-specific morphological characters of D. adenanii, according to its original description, fall into the morphological variability of D. b...

The ecological requirements and biology of the Tetrigidae are almost unknown. The aim of the present work is to contribute to the knowledge of Tetrix bolivari, one of the least studied species of European Tetrigidae, by investigating its seasonal and daily activity, food biology, and vibratory communication. Adults of T. bolivari were found from Ma...
