V únoru 1986 jsem fotografoval motýlí faunu Malajského poloostrova, západně od vrchoviny Cameron Highlands (asi 600 m n. m.). Pořídil jsem i několik snímků otakárka Lamproptera meges. Tento motýl v letu připomíná spíše vážku nebo šídlo, z čehož plyne jeho výhoda ve smyslu Batesova typu mimikry. Rozpětí má kolem 5 cm, ale zadní křídla vybíhají v 4 cm dlouhé ostruhy (obr. 1). Vnější polovina předních křídel je průsvitná a za letu neviditelná, podobně jako křídla hmyzu, který motýl napodobuje. Obývá lesní porosty v bezprostřední blízkosti tekoucí vody. Pravidelně usedá na vlhké bahno nebo písek a saje vodu obsahující sodné ionty a různé látky nutné pro výživu. and Our unintentional picture shows a Malaysian papilionid periodically every 4–6 seconds expelling water from its anus.
The article first outlines the three major phases of Islamization of Bengal, focusing particulary on the phase of mass Islamization of rural native population, which was characterized by strong tendencies to syncretism with local religious traditions. This syncretistic environment is then described in more detail with special emphasis on the Naths, Vaisnava Sahajiya, and their generally Tantric-yogicbackground. The literature that emerged from this environment is further introduced as a vehicle of mediation between the Perso-Arabic Islamic tradition and Bengalic cultural milieu. As this milieu was conspicuously Tantric in character, the article pays special attention to esoteric Islamic texts, which reveal considerable popularity of various Tantric-yogic notions and bodily techniques among Bengali Muslims., Kristýna Himmerová., and Obsahuje seznam literatury
In 2018, during a rescue archaeological excavation taking place in one of the gardens of Staré Město near Uherské Hradiště, 23 early medieval graves containing skeletal remains of 26 individuals were detected. The site is situated on the northern border of the well-known Great Moravian burial ground ‘Na Valách’. In a large number of the newly excavated graves, greater or lesser deviations from the usual funeral rite were recorded. While the established burial rite in Great Moravian society means the deceased lies on their back in the supine position with extended extremities and head towards the west, here we found skeletons in very different orientations, lying in a prone or crouched position, or, at least, with unusual positions of their upper or lower limbs. Additionally, some of the graves contained incomplete or no skeletons. There is also one double burial and a triple burial, and several graves in superpositions. In nine graves, objects of material culture were found, the most important of them come from the rider’s grave 20/2018. The presented study aims to interpret the burial contexts using the bioarchaeological approach, which is, however, affected by the quality of the preserved finds, especially skeletal remains.
Although it has been generally reported that carnivorous plants of the genus Nepenthes are not very selective about their prey, the new studies have shown that the genus is under a strong selective pressure to specialize in certain prey. Moreover, novel nutrient sequestration strategies have recently been described, including leaf litter and faeces utilization. Thus the genus Nepenthes is a new and illustrative example of adaptive radiation with regard to nitrogen sequestration strategy. and Andrej Pavlovič.
