Methods in Ecology and Evolution, EarlyView.Abstract Molecular identification of insect food webs can accurately reveal complex trophic interactions and serve as a foundation for understanding ecosystem functioning and advancing biodiversity conservation. This process typically involves DNA library construction, high‐throughput sequencing and subsequent steps, including data assembly, annotation,

A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

A Research on Model of Community Participation in Ecotourism of Marine Park ——A Case Study on Zengcuoan and Huangcuo [PDF]
, 2015 滨海生态旅游是滨海旅游可持续发展的一种方式，是以旅游目的地生态、经济与社会和谐共生为目标的发展。为了保证这一目标的有效持续进行，我国目前已在原来海洋特别保护区的基础上建设以“生态旅游”为主导功能的国家海洋公园制度。无论是对滨海生态旅游的发展还是国家海洋公园的建设管理，社区参与都是其可持续发展的重要内容。社区参与有助于MPAs生态资源环境的保护，沿岸传统风俗文化的维护，是滨海旅游目的的可持续发展的有效方式。国外在生态旅游开发管理和海洋保护区建设管理方面都积累了较为丰富的经验 ...

The collective application of shorebird tracking data to conservation
Conservation Biology, EarlyView.Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Ecological Studies of Marine Virus and its Viral Lysate [PDF]
, 2015 病毒是海洋生态系统中数量最多、多样性最为丰富的一类生命形式，具有极为重要的生态地位。为了深入认识海洋浮游病毒及其裂解浮游细菌释放的裂解产物的生态效应，本论文首先研究了西太平洋典型寡营养海区的浮游病毒对浮游细菌的致死效应；接着研究病毒裂解产物如何在不同营养水平（寡营养和富营养）特征的海洋水体中影响浮游细菌的生长、群落组成等生态特性。此外，本论文以海洋生态系统中一类生态地位非常重要的浮游细菌-玫瑰杆菌（Roseobacter）为研究对象，对其裂解性病毒进行了分离纯化和鉴定 ...

Differences in characteristics between naturalized threatened plants and other threatened plants
Conservation Biology, EarlyView.Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.

生态承载力与生态系统生产总值耦合的生态系统服务评估—以福建省长汀县为例
Shuitu Baochi Xuebao, 2021 生态系统质量是区域探索生态优先、绿色发展为导向的高质量发展的重要基础。开展区域生态系统服务评估可获取国土空间生态本底特征，为生态系统保护格局构建提供现状底图，明确生态系统修复重点、国土空间优化提供导向。以长汀县为例，基于地区生态典型性、区域生物量差异及公众支付意愿与能力构建特色评价指标，采用生态承载力与生态系统生产总值耦合研究方法，对长汀县生态系统服务进行县域、镇域、村域及系统斑块等多尺度评估。结果表明：长汀县生态系统服务等级空间分布符合区划规律，大致呈中间低、四周高的特征；尺度细化使结果分布异质性更强，

Phytoplankton community structure and microbial loop during giant jellyfish blooms in the Yellow Sea [PDF]
, 2015 大型水母暴发已是全球性的海洋生态灾害，作为东亚海域水母高发区，黄海的水母暴发已经对生态系统造成了显著影响，然而水母暴发对浮游生态系统影响或生态效应尚不清楚。本论文通过现场大面调查和培养实验等研究手段，利用高效液相色谱、流式细胞仪等多种分析方法，在水母暴发年份对我国黄海大型水母沙海蜇(Nemopilemanomurai)暴发区的浮游植物及微食物环各主要组分相互关系展开研究。根据2011年~2014年航次调查研究和实验生态研究数据，取得以下主要结果： 1 ...
