Study on restoration of benthic macrofaunal community in Xiatanwei artificial mangrove wetlands, Tong’an Bay [PDF]
, 2016 红树林生态系统处于海洋与陆地的动态交界面，是我国三大海岸带生态系统之一。底栖动物(包括大型、小型和微型底栖动物)是红树林生态系统的重要组成部分，同时也是该生态系统内物质循环、能量流动中积极的消费者和转移者。关于同安湾潮间带、潮下带和红树林湿地大型底栖动物群落生态的研究已有报道，但关于同安湾人工红树林湿地大型底栖动物群落恢复、演替和功能群方面的研究稀少，且关于红树林群落边缘大型底栖动物的群落效应的研究未见报道。 本研究选取同安湾下潭尾人工红树林湿地作为研究区域 ...

Lessons learned from screening potential other effective area‐based conservation measures
Conservation Biology, EarlyView.Abstract Other effective area‐based conservation measures (OECMs) are sites that deliver effective biodiversity outcomes irrespective of their management objectives. These areas are widely expected to play an important role in efforts to protect 30% of Earth by 2030.

Conservation Biology, EarlyView.Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Microphase separation of mixtures of two diblock copolymers(两嵌段共聚物共混体系的相分离研究)
Zhejiang Daxue xuebao. Lixue ban, 2009 用耗散粒子动力学方法(DPD)研究了由两种不同成分组成的两嵌段共聚物组成的混合体系在纳米尺度下的自组装行为.两种嵌段共聚物的聚合度相同,在稳定状态下,纯嵌段共聚物1呈层状有序结构,纯嵌段共聚物2呈无序或六角柱状结构.DPD研究表明,在两者混合体系中,随着嵌段共聚物2体积分数的增加,嵌段共聚物1只出现了层状的有序相,而嵌段共聚物2则呈现出从球状相到柱状相再到层状有序相的有趣变化,随着嵌段共聚物2对称性的增强,其形成的有序相所占的体积分数区域越小.同时,通过混合体系单体密度分布曲线和末端距分布情况 ...

Survival strategy of Calanus sinicus in the northwest of the South China Sea [PDF]
, 2015 中华哲水蚤（Calanussinicus）是我国近海生态系统的特征种之一，在我国浮游生物学和近海生态系统动力学研究中具有重要意义。本文基于2006~2007年在南海西北部进行的四个季节的航次调查，研究了中华哲水蚤的空间分布和季节变化，以广义可加模型为工具量化分析了影响中华哲水蚤丰度变化的重要环境因子，同时探讨了南海西北部中华哲水蚤的种群来源和生存策略问题。主要研究结果如下： （1）中华哲水蚤的丰度变化具有显著的季节差异。在北部湾调查区域，春季平均丰度为2.37±8.00ind/m3，占桡足类总丰度的6 ...
