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 ...

An Integrated Research on Marine Biodiversity Conservation at the core of Regional Ocean Governance [PDF]
海洋生态系统是人类赖以生存和发展的重要物质和文化基础。随着人类社会经济活动的范围和强度不断拓展和加深,全球海洋生物多样性及其持续向人类提供生态系统服务的功能面临着日益严峻的破坏和威胁。如何加强和完善海洋生态系统养护和管理,实现海洋生物多样性可持续保护和发展,是全球共同面临的重要课题,同时也考验着人类在自然-社会生态系统互动中形成怎样的关系和响应策略问题。海洋生物多样性保护作为人类共同关切事项所具有的公共产品属性要求全球、区域和国家多层面采取集体行动来共同应对。在此背景下 ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

The Study of Original Ecological Landscape Regeneration Design Under theVisual of the Land Art——Xiamen Huandao Road [PDF]
目前,全球正面临着经历一场声势浩大并将持续下去的生态变革。人类时刻关注着环境问题(生态污染、全球变暖等)、社会问题(人性冷漠、交流障碍等)、文化问题(信仰缺失、文化断层等)与能源危机等现实问题。而在生态变革之中,真正的挑战是将现有资源进行修复与再生,以便更好的分配与使用。在信息爆炸的当下,各界人士针对生态问题给出了相应的解决方案,重塑生态系统、人文景观的再造与再生循环系统设计作为主要的三种方案,在实践中收到积极的效果。近年来,艺术家也参与到这一时代洪流中,摒弃无作为的个人创作,承担起更多的社会责任 ...

Harnessing social media data to track species range shifts
Abstract Biodiversity monitoring programs and citizen science data remain heavily biased toward the Global North. Especially in megadiverse countries with limited biodiversity records, incorporating social media data can help address existing data gaps.

利用生态足迹的理论与方法,对陕西关中渭河盆地,1986~2002年的生态足迹、生态承载力、生态盈余/亏损进行了测算。提出了生态压力指数的概念,建立了生态压力指数测算模型以及生态足迹、生态承载力、生态盈余及生态安全度变化预测模型,并对本地区万元GDP的生态足迹需求进行了测评。研究结果表明:①本地区生态承载力呈减少趋势;②生态足迹均呈现增加趋势;③1986~2002年生态压力指数从0.75增长为1.20,增长幅度为0.45,增长幅度较大;④关中盆地已严重超载,处于不安全状态 ...

Response of stable states of simple marine plankton ecosystems to warming [PDF]
温度是影响海洋浮游生态系统结构和功能的关键环境因子。从上个世纪初以来,受到人类排放温室气体的影响,全球海洋平均温度明显升高。但温度影响浮游生态系统变化和浮游生物生物量变动的机制还不明确。本文采用理论模型与实验生态相结合的方法探究温度对简单浮游生态系统稳态的影响,并一同考虑营养盐的输入,得到如下主要结果: 1.建立描绘以亚心形扁藻(PlatymonasSubcordiformis,绿藻)为被捕食者、海洋尖尾藻(Oxyrrhismarina,甲藻 ...
