| 3 | Linking molecular deadwood-inhabiting fungal diversity and community dynamics to ecosystem functions and processes in Central European forests显示文摘Fungi play vital roles in the decomposition of deadwood due to their secretion of various enzymes that break down plant cell-wall complexes.The compositions of woodinhabiting fungal(WIF)communities change over the course of the decomposition process as the remaining mass of wood decreases and both abiotic and biotic conditions of the wood significantly change.It is currently not resolved which substrate-related factors govern these changes in WIF communities and whether such changes influence the deadwood decomposition rate.Here we report a study on fungal richness and community structure in deadwood of Norway spruce and European beech in temperate forest ecosystems using 454 pyrosequencing.Our aims were to disentangle the factors that correspond to WIF community composition and to investigate the links between fungal richness,taxonomically-resolved fungal identity,and microbial-mediated ecosystem functions and processes by analyzing physico-chemical wood properties,lignin-modifying enzyme activities and wood decomposition rates.Unlike fungal richness,we found significant differences in community structure between deadwood of different tree species.The composition of WIF communities was related to the physico-chemical properties of the deadwood substrates.Decomposition rates and the activities of ligninmodifying enzymes were controlled by the succession of the fungal communities and competition scenarios rather than fungal OTU richness.Our results provide further insights into links between fungal community structure and microbialmediated ecosystem functions and processes. | Björn Hoppe Witoon Purahong Tesfaye Wubet Tiemo Kahl Jürgen Bauhus Tobias Arnstadt Martin Hofrichter François Buscot Dirk Krüger | 2016 | Fungal Diversity2016，，2： | 2 |
| 4 | Shot-noise limited, supercontinuum-based optical coherence tomography显示文摘We present the first demonstration of shot-noise limited supercontinuum-based spectral domain optical coherence tomography(SD-OCT)with an axial resolution of 5.9μm at a center wavelength of 1370 nm.Current supercontinuumbased SD-OCT systems cannot be operated in the shot-noise limited detection regime because of severe pulse-topulse relative intensity noise of the supercontinuum source.To overcome this disadvantage,we have developed a low-noise supercontinuum source based on an all-normal dispersion(ANDi)fiber,pumped by a femtosecond laser.The noise performance of our 90 MHz ANDi fiber-based supercontinuum source is compared to that of two commercial sources operating at 80 and 320 MHz repetition rate.We show that the low-noise of the ANDi fiber-based supercontinuum source improves the OCT images significantly in terms of both higher contrast,better sensitivity,and improved penetration.From SD-OCT imaging of skin,retina,and multilayer stacks we conclude that supercontinuumbased SD-OCT can enter the domain of shot-noise limited detection. | Shreesha Rao D.S.

| 5 | 西印度洋地区海草生态系统显示文摘海草是海洋被子植物,广泛分布在温带和热带的海岸带水域,是地球上水生生态系统中最具生产力的生物之一。在西印度洋地区大概有13种海草,这些海草覆盖了12000kg海岸线的近岸柔软海底广大区域。海草床一般分布在潮间带和潮下带,有时向下延伸至40m,并经常出现在珊瑚礁和红树林附近。由于具有很高的初级生产力和复杂的栖息环境,海草供养了许多底栖生物和浮游生物。许多鱼类和贝类,包括那些具有商业价值的种类都被吸引到海草栖息地,将海草作为其食物来源和避难场所,特别是在它们的幼年期。分布在西印度洋海草床附近广泛而丰富的鱼类资源就足以说明这一点。这些鱼分别属于天竺鲷科、亚科、玻甲鱼科、银鲈科、虾虎鱼科、隆头鱼科、裸颊鲷科、笛鲷科、单角亚科、鹦嘴鱼科、科、篮子鱼科、海龙科和Teraponidae科。因此,西印度洋地区的海草生态系统无论对当地还是整个地区的渔业发展都是非常有价值的资源。尽管如此,与其他地区相比,该地区有关海草资源的研究还十分缺乏,而且大多数研究也都集中在植物多样性和生态学上。本文主要阐述西印度洋地区海草床研究现状,特别强调鱼类和渔业。目前,该课题的大多数研究主要是在东非海岸开展的,如肯尼亚,坦桑尼亚,莫桑比克以及南非东部地区,而在索马里和西印度洋地区的岛屿国家(塞舌尔、科摩罗、法属留尼旺岛、毛里求斯、马达加斯加等)此类研究却很少,有关海草鱼类生态系统的论文也少有发表,而且大部分都是描述性的。因此,需要通过研究和实验获得有关描述模式和处理方法的科学知识。关于海草鱼类群落的定量研究,类似本文所介绍的案例研究在西印度洋地区是很少的,而这些研究对于渔业的管理前景而言是必不可少的。值得强调的是由于海岸人口的不断增长以及人类活动的侵扰给该地区海草床带来的压力与日俱增,如污染,海水富营养化,沉积作用,捕鱼以及无脊椎动物的采集等活动,而这些活动对于海草床的影响却鲜为人知。因此,需要开展广泛的研究,为西印度洋地区海草生态系统可持续管理提供有用的信息服务。 | Martin Gullstrm Maricela de la Torre Castro Salomo O.Bandeira Mats Bjrk Mattis Dahlberg Nils Kautsky Patrik Rnnbck Marcus C.hman 章任群 | 2002 | AMBIO-人类环境杂志2002，31，7： | 2 |
