Meiofauna Communities in Artificial Mangrove Wetland inTong’an Bay [PDF]
, 2015 红树林是热带亚热带海岸潮间带受周期性潮水浸淹，以红树植物为主体的常绿灌木或乔木组成的木本生物群落，是连接陆地和海洋的特殊森林。我国对红树林湿地的植物研究较多，对底栖动物研究较少；对红树林湿地大型底栖动物研究较多，对小型和微型底栖动物研究较少，特别是对人工红树林湿地小型底栖动物的研究更少。 本研究于2014年2月、5月、8月和11月，在同安湾的下潭尾和白兔山人工红树林湿地进行了4个季度小型底栖动物定量取样，系统的研究了小型底栖动物的类群组成、丰度、生物量和多样性等，并分析了自由生活海洋线虫的种类组成、丰度、

Wildlife Letters, EarlyView.Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Study on the seasonal dynamics of small mammals in Jinhua City(金华城区小型兽类数量季节消长的研究)
Zhejiang Daxue xuebao. Lixue ban, 2002 自1997年1月至1999年12月,选择金华城区的居民区、宾馆、粮库和工厂等4种生境5个调查点,每月以夹夜法对小型兽类数量的季节消长进行研究.结果表明,金华城区褐家鼠(Rattus norvegicus)的捕获率为0.58%、黑线姬鼠(Apodemus agrarius)0.26%、臭鼩鼱(Suncus murinus)0.24%、黄胸鼠(Rattus flavipectus)0.12%、小家鼠(Mus musculus)0.05%;捕获率的季节消长呈现以6月和9月为高峰的双峰型曲线 ...

Distribution Pattern of Taxonomic Diversity of Fish Community in Four Typical Mangrove Areas, China [PDF]
, 2016 红树林区不仅能为许多海生和陆生生物提供栖息地和食物，还是许多鱼类的育幼场和产卵场，因此红树林区生物多样性成为当今生态学研究热点之一。过去对红树林区鱼类群落的研究多采用传统生物多样性指数，然而传统生物多样性指数在实际运用过程具有过多注重物种丰富度、未考虑物种在分类学上的差异等缺陷。分类多样性指数既考虑了群落中物种数量和均匀程度，也考虑了物种分类地位和生态学上的差异，更全面更有说服力。 为全面了解中国红树林区鱼类物种多样性分布格局，本研究选取福建漳江口、广西茅尾海、广西山口、海南东寨港四个典型的红树林区 ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Zhejiang Daxue xuebao. Lixue ban, 2007 对天台大雷山4个不同生境（常绿阔叶林、灌丛、竹林和杉木林）夏蜡梅群体的果实、种子形态变异及其与环境因子的相关性进行了研究.测量的果实和种子12项形态学指标表明，果实和种子的性状以灌丛生境最优、其次是竹林生境、最差的是常绿阔叶林生境.表型性状在群体间和群体内都存在着一定程度的变异，其中群体间的变异系数的平均值从61.71（每果种子数）到7.51（种子厚）.夏蜡梅种子形态较果实形态穗定.单因素方差分析显示，夏蜡梅果实和种子形态在不同生境间差异显著，其中80%以上的变异来源于生境内 ...
