中国鹤类现状及其保护对策

中国有9种鹤类,其中灰鹤（Grus grus）、黑颈鹤（Grus nigricollis）、丹顶鹤（Grus japonensis）、白枕鹤（Grus vipio）、赤颈鹤（Grus antigone）、蓑羽鹤（Anthropoides virgo）在中国进行繁殖。中国政府为保护鹤类采取了大量有效措施。本文在结合当前鹤类数量和保护现状的基础上,对中国鹤类的保护对策进行探讨。

Phylogeny of the Genus Cladonia s.lat. (Cladoniaceae, Ascomycetes) Inferred from Molecular, Morphological, and Chemical Data

Phylogenetic relationships within the genus Cladonia , including Cladina (Cladoniaceae, Lecanoromycetes), were reconstructed based upon simultaneous analyses of DNA sequences and morphological and chemical data. We used sequences from the internal transcribed spacer 1 (ITS1), the 5.8 rDNA gene, and the internal transcribed spacer 2 (ITS2) of the nuclear rDNA gene cluster, and partial sequences from the protein-coding β-tubulin gene. The analyses included 235 specimens of 168 taxa representing all currently recognized sections of Cladonia and Cladina and the outgroup genera Cladia, Pycnothelia , and Ramalea . Analyses were performed using optimization alignment with three different parameter values. The results of all analyses support the inclusion of Cladina in Cladonia . The current sectional division of Cladonia was not supported, and a new provisional classification for the genus is proposed.     

Polysaccharides of lichenized fungi of three Cladina spp.: significance as chemotypes

The chemical structures of nigerans, an alpha-glucan, laminarans, a beta-glucan, galactoglucomannans and galactomannoglucans of three species of Cladina, namely C. arbuscula, C. confusa and C. substenius, were determined and compared. According to chemical and spectroscopic analyses, the glucans investigated to date, which have been isolated in 15 Cladonia species, as well as the galactomannoglucans and galactoglucomannans, have similar principal structures. This suggests that, in terms of polysaccharide structure, Cladonia and Cladina genera do not show differences. DNA studies support this idea and it is proposed that Cladina be reduced to a synonym under Cladonia.     

Cladonia azorica in the British Isles

Abstract:Cladonia azorica is widespread in western Great Britain, mainly as the grey colour-form lacking usnic acid. Cladonia azorica is distinguished from the related species C. portentosa and C. mediterranea by the presence of fumarprotocetraric acid, and from C. ciliata by a number of characters including the presence of perlatolic acid. The structure of the pycnidial wall may have some taxonomic significance in Cladonia subgenus Cladina.

Net photosynthetic recovery in subarctic lichens with contrasting water relations

Summary The rates of net photosynthetic recovery after wetting for six subarctic lichens were related to their drying rates under laboratory conditions. Net photosynthetic recovery was described by the three parameters of the Von-Bertalanffy equation: T _o and K, related to the rates of resaturation respiration and gross photosynthetic recovery, and P _max, the photosynthetic maximum attained at full recovery. The time to full photosynthetic recovery ranged from 143 to 510 min and was positively correlated with the drying rate of the thallus. In order from most to least rapid recovery, the species are Coelocaulon divergens, Cetraria cucullata, Alectoria ochroleuca, Cladina stellaris, Nephroma arcticum, and Cladonia sulphurina.In nature the high evaporative resistance or low waterholding capacity characterizing fast-drying species will result in short, frequent cycles of wetting and drying which induce carbon losses. In such situations a rapid photosynthetic recovery should be adaptive since it increases photosynthetic carbon gain during a period of metabolic activity. We hypothesize that fast-drying species achieve their rapid photosynthetic recovery by an increased desiccation-tolerance which has a metabolic cost associated with it. In slowdrying species a rapid recovery is not favored by natural selection since these species can take advantage of longer photosynthetic activity periods and are exposed less frequently to deleterious wetting and drying cycles. Future studies of lichen distribution and productivity should take into account the recovery phenomena.
