Phytoplankton diversity and assessment of trophic state in Futian Mangroves in Shenzhen [PDF]
, 2010 通过监测深圳福田红树林水体浮游植物,掌握浮游植物多样性组成和时空分布特征,并利用浮游植物群落多样性指数结合生物量、数量,对水体营养状态进行评价。结果表明,浮游植物种类少,数量大。硅藻分布广泛,在种类和数量上占主导地位,优势种为微小小环藻(CyClOTEllA CASPIA)和诺氏海链藻(THAlASSIOSIrA nOrdEnSkI ldI)等,一些耐污染的藻类,如小颤藻(OSCIllATOrIA MInIMA)、裸藻(EuglEnASPP.)在特定季节成为一些站位的优势种。浮游植物种类组成时空变化显著,

Integrative Conservation, Volume 4, Issue 4, Page 569-583, December 2025.Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...

Species composition and seasonal variation of netz-phytoplankton in the eastern marginal China seas [PDF]
, 2015 为揭示中国东部陆架边缘海浮游植物群落季节变化规律,根据2006年6–7月、2007年1–2月、2007年11月和2009年4–5月在中国东部陆架边缘海域(25.00°–39.00°n,118.00°–129.00°E)进行的综合采样调查,对调查海域网采浮游植物(网孔直径77μM)的物种多样性和分布特征进行了研究。4个航次共鉴定出浮游植物4门70属257种(不包括未定名种),其中硅藻是主要功能群,其次是甲藻,主要的优势种为骨条藻(SkElETOnEMA SPP.)、细弱海链藻(THAlASSIOSIrA ...

Characterizing China's Illegal Trade in Avifauna on Social Media 中国社交媒体上非法鸟类贸易的特征分析
Integrative Conservation, Volume 4, Issue 4, Page 616-626, December 2025.Worldwide, illegal wildlife trade is an increasing threat to species conservation. Here, we used the social media data to characterize China's illegal online trade in avifauna for conservation implications. Our results found that 178 avian species have been posted online for illegal trading. ABSTRACT The illegal wildlife trade poses a growing threat to

Comparative study on community ecology of transition zone along Eucalyptus citriodora to Acacia confusa forest stands [PDF]
, 2011 近年来，外来树种桉树在我国大量种植，产生了巨大的经济效益，但同时，其速生性、较强的化感作用等特性，也带来一些负面的环境问题，评估桉树种植的环境生态影响成为当前林业生态研究的热点。目前大量的研究集中在桉树群落生态学上，而关于桉树与乡土树种过渡带的群落生态学的综合比较研究未见报道。 为此，本文针对无居民海岛柠檬桉（Eucalyptuscitriodora）林与台湾相思（Acaciaconfusa）林过渡带三种林分林下层植被群落生态、林分凋落物及其分解动态进行了研究 ...
