Snad každý, kdo se vypraví do zemí jihovýchodní a východní Asie nebo sleduje cestopisné pořady v televizi, se setká s množstvím buddhistických památek, mezi nimiž dominují zpravidla sochy sedících, stojících či ležících Buddhů. Co však tato zobrazení vlastně znamenají, k čemu odkazují a kde vůbec vznikla jejich první podoba? Článek se pokusí odpovědět na některé z těchto otázek a na příkladu čtyř důležitých motivů z gandhárského sochařství ukáže, jak vypadala nejranější zobrazení scén ze života Buddhy a co se z nich můžeme dozvědět., The article concerns the iconography of early Buddhist art. It focuses on four of the most important events in Siddhartha Gautama's life, the Great departure, the Enlightenment, the First sermon, and Mahaparinirvana, as portrayed on the Gandharan reliefs. The typers of representation of the Buddha and Bodhisattva in the anthropomorphous form, which had developed in the region of ancient Gandhara during the reign of the Kushanas, influenced Buddhist art in other Asian countries., Kateřina Svobodová., and Obsahuje bibliografii
Cucolepis gen. n. is erected as monotypic for Cucolepis cincta sp. n., a new species of cyclophyllidean cestode of the family Paruterinidae. The new species is described from the squirrel cuckoo, Piaya cayana Lesson (Aves: Cuculiformes), taken from two localities in Paraguay in 1984 and 1985. This new genus is most similar to the genus Triaenorhina Spasskii et Shumilo, 1965 in terms of the hook morphology and large epiphyseal structures extending from both the handle and guard, but differs in several aspects of the strobilar morphology, such as the shape of the cirrus sac, genital atrium, uterus and paruterine organ. The strobilar morphology of the new genus strongly resembles that of the genus Francobona Georgiev et Kornyushin, 1994, especially the shape of the cirrus sac and genital atrium, yet Francobona spp. lack the developed epiphyseal structures observed in species of Cucolepis and Triaenorhina. Previous records and the nature of parasite-host associations between cuculiform birds and their cestode parasites are discussed.
A new species of parasitic nematode, Cucullanus oceaniensis sp. n., is described from the intestine of the giant mottled eel Anguilla marmorata (type host) from Futuna Island (Wallis and Futuna Islands, Polynesia) and from A. marmorata and Anguilla sp. (cf. obscura) from Fiji Islands (Melanesia, South Pacific). The main distinguishing characteristics are the length of spicules (668-1,020 µm), situation of deirids (slightly anterior to the oesophago-intestinal junction) and the excretory pore (some distance posterior to the end of oesophagus), and the arrangement of caudal papillae in the male. It is the third known species of Cucullanus from Oceania and the first one reported from freshwater eels in the region of South Pacific. Cucullanus faliexae Morand et Rigby, 1998 is considered a junior synonym of Cucullanus australiensis Baylis, 1927.
A new nematode species, Cucullanus pargi sp. n., is described from the intestine and pyloric caeca of the grey snapper, Lutjanus griseus (Linnaeus), off the southern Quintana Roo coast, Mexico. This species shows similar morphological features as cucullanids occurring in marine and brackish-water fishes; however, it differs from all other species in the length of spicules, arrangement and number of caudal papillae, position of the excretory pore and deirids. Cucullanus pargi is the third species of this genus described from fishes in Mexico and the second one from Mexican marine fishes.
Forty-four genotypes from the rice germplasm were identified under photoinhibition/photooxidation and shade conditions and divided into four basic types: (1) cultivars tolerant to both photooxidation and shading, (2) cultivars tolerant to photooxidation but sensitive to shading, (3) cultivars tolerant to shading but sensitive to photooxidation, and (4) cultivars sensitive to both photooxidation and shading. Photosynthetic characteristics of a cultivar tolerant (cv. Wuyugeng 3) and a cultivar sensitive (cv. Xiangxian) to photooxidation and shading were compared. The photochemical efficiency (Fv/Fm) of photosystem 2 (PS2) and the content of PS2-D1 protein in the tolerant cultivar Wuyugeng 3 decreased less under photooxidative conditions as compared with Xiangxian. Under similar conditions, superoxide dismutase was induced rapidly to a higher activity and the active oxygen (O-) built up to a lower level in Wuyugeng 3 than in Xiangxian. Net photosynthetic rate (PN) decreased by 23 % in Wuyugeng 3 vs. 64 % in Xiangxian. Shading (80 %) during the booting stage caused only small decreases (7-13 %) in ribulose-1,5-bisphosphate carboxylase activity and PN in Wuyugeng 3 but severe decreases (57-64 %) were observed in Xiangxian which corresponded to the decreases in grain yield of the two cultivars (38 and 73 %, respectively). We described a simple and effective screening method and physiological basis for breeding crops for enhanced tolerance to both high and low irradiance. and Demao Jiao, Xia Li.
