Kudlanka nábožná (Mantis religiosa) je příklad teplomilného druhu, který v posledních letech začal expandovat i do severnějších oblastí Evropy. Na základě studia mitochondriálních markerů se ukázalo, že v rámci Evropy kudlanky náleží do tří odlišných genetických linií. Tyto linie (západoevropská, středoevropská a východoevropská) se postupně po poslední době ledové šířily na sever z různých glaciálních refugií. Tuto teorii také podporují paleoklimatická data a distribuční modely možného šíření kudlanek po poslední době ledové., The Praying Mantis (Mantis religiosa) is an example of a thermophilic species, which has recently been expanding northwards across Europe. Based on the study of mitochondrial genes, it has been shown, that the European M. religiosa belong to three different genetic lineages (West-, Central- and East-European). These lineages have been gradually spreading northwards from different glacial refugias after the last glacial period. This theory has also been supported using paleoclimatic data and distribution models of the potential spread of M. religiosa after the last glacial period., and Jakub Vitáček, Petr Janšta.
Emp-AKH is a member of the large adipokinetic hormone (AKH) family of peptides. This peptide family appears to occur in the corpora cardiaca of all insect species and its members are involved in regulating substrate mobilisation. The secondary structure of Emp-AKH has been studied in the presence of sodium dodecyl sulfate micelles by comparing data obtained from Nuclear Magnetic Resonance and molecular dynamics simulations. The lowest energy conformer obtained in this study has a turn consisting of residues 5-8 and a tail consisting of the first five residues., Igor Z. Zubrzycki, Gerd Gäde, and Lit
The aim of this review is to explain the functional significance of mantis peering behaviour from an entomological perspective. First the morphological and optical features of the mantis compound eye that are important for spatial vision are described. The possibility that praying-mantises use binocular retinal disparity (stereopsis) and other alternative visual cues for determining distance in prey capture, are discussed. The primary focus of the review is the importance of peering movements for estimating the distance to stationary objects. Here the following aspects are examined: (1) Direct evidence via object manipulation experiments of absolute distance estimation with the aid of self-induced retinal image motion; (2) the mechanism of absolute distance estimation (with the interaction of visual and proprioceptive information); (3) the range of absolute and relative distance estimation; (4) the influence of target object features on distance estimation; and (5) the relationship between peering behaviour and habitat structures, based on results of studies on three species of mantis., Karl Kral., and Obsahuje seznam literatury
