This article refers to the rich vegetation on the rocky slopes along the Achensee (Tyrol, Northern calcareous Alps, Karwendelalpen) described by Professor Anton Kerner 150 years ago. The vegetation today is much less diverse, the subalpine species abundant in the last centuries are absent while the species of mixed mountainous forest prevail. The abundance of the Heather (Calluna vulgaris), which was not mentioned by A. Kerner, may indicate acidification due to acid rain. And the retreat of subalpine species may indicate the on going change to a warmer climate. and Jarmila Kubíková.
A large outbreak of haemolytic uraemic syndrome and bloody diarrhoea caused by the pathogenic E. coli strain in Germany in 2011 has increased attention to foodborne diseases – bacterial infections linked to the consumption of fresh produce. Since the early 1990s, evidence is emerging that en - teropathogenic bacteria have the ability to grow and persist on crop plants for prolonged periods of time, including until harvest, and to be the carrier of illness. and Václav Kůdela.
Havel’s perception of nature does not in - volve a scientific interest in its mystery and beauty, he suspected science of ultimately aiming to just utilize the nature. Nature is above all the endangered victim of the man’s unscrupulousness and exploitation. Hence Havel highlights landscape rather than nature in his texts. When he talks about nature protection, he also includes landscapes, villages and settlements, he often speaks about lapses with regard to present-day urbanism, and about human pride towards the environment. In contrast, he advocates reverence and respect for „nature, land and the historical heritage“. and Jan Sokol.
The existence of pollination syndromes and the degree of specialization in these systems are still discussed. Three examples from the tropical mountain communities in the Bamenda Highlands (Cameroon) show that a detailed knowledge of plants and their visitors and pollinator behavioral studies are necessary before evolutionary hypotheses can be formulated., Michael Bartoš, Eliška Padyšáková, Štěpán Janeček., and 7 barev. fot.
