Abstract

We studied the endolichenic fungal communities from saxicolous lichens occupying the cobbles at Nahal Boker, the central Negev Desert, Israel. Overall, 101 species belonging to 64 genera were isolated from 12 lichen species collected in three seasons from the south-facing slope (SFS) and north-facing slope (NFS) of the wadi. The endolichenic communities possessed a set of traits, which helped them to cope with harsh internal and external conditions. It included a prevalence of melanin-containing fungi with thick-walled and multicellular spores and a comparatively high contribution of thermotolerant species and species with meiospore-producing life cycle stage at the more microclimatically severe SFS. Species richness and isolate density of endolichenic communities was the highest in fruticose lichens with thick and wrinkled thalli, and the lowest in endolithic species possessing thin and smooth thalli. The communities from lichens formed a more diverse group than those from surrounding cobbles probably due to the influence of various species of lichens belonging to different growth forms.

以色列内盖夫沙漠中部Nahal Boker沙地地衣内生微真菌群落的组成和多样性

我们研究了以色列内盖夫沙漠中部Nahal Boker鹅卵石上的地衣内生真菌群落。从三季采集的12种地衣中，共分离出64属101种，分布于瓦迪河南岸和北岸。内生地衣群落具有一系列特征，这有助于它们应对恶劣的内部和外部条件。它包括具有厚壁和多细胞孢子的含黑色素真菌的流行，以及在更为小气候严重的SFS中，耐热物种和具有产生小孢子生命周期阶段的物种的贡献相对较高。内生地衣群落的物种丰富度和分离物密度在具有厚而褶皱铊的古生地衣中最高，而在具有薄而光滑铊的旧石器时代物种中最低。地衣的群落比周围鹅卵石的群落更为多样，这可能是由于不同生长形式的地衣物种的影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
