The article traces the role and image of the wood and the tree in the culture of Ancient China as emerging from the transmitted literature of the Warring States period. Although this topic has already been touched upon in some previous studies, such as Mark Elvin's The Retreat of the Elephants, no comprehensive description based on at least nearly exhaustive systematization of respective data available to us in primary sources has been presented yet, especially for trees. In this paper, virtually all recorded modes of approaching the phenomena by the learned men of the Warring States are summarized and supplied with extensive reference to ancient texts. Apart from other issues, it clearly demonstrates that the skeptical stance to ancient Chinese love for nature and to the ecological ethos of traditional Chinese culture is highly justified., Lukáš Zádrapa., and Obsahuje bibliografii
Sazná nemoc kůry je méně známé onemocnění způsobené houbou Cryptostroma corticale (Ascomycota), s ostrůvkovitým výskytem v Evropě. Postihuje zejména javory kleny (Acer pseudoplatanus) a jejich hromadná vymírání byla zaznamenána u stromů oslabených stresem, především po nadprůměrně suchých a horkých letních měsících. Nedávný výskyt onemocnění v České republice podnítil studium druhu C. corticale a jeho rozšíření v Praze. Výsledek naší čtyřleté studie prokázal, že napadena je minimálně čtvrtina klenů v pražských parcích., Sooty bark disease is a less known disease caused by fungal species Cryptostroma corticale (Ascomycota), with patchy incidence in Europe. It mainly affects Sycamore (Acer pseudoplatanus), and its mass dieback was observed in trees weakened by stress, especially after the exceptionally dry and hot summer months. Recent record of the disease in the Czech Republic prompted the research of C. corticale and its occurrence in Prague. The results of our four-year study showed that at least 25 % of Sycamore trees in Prague parks are infected., and Ivana Kelnarová, Ondřej Koukol, Karel Černý.
