国外保护野生动物法规简介

open access: yes野生动物学报, 1989
一、国外保护野生动物的立法为了保护野生动物,世界上许多国家制定了保护野生动物的综合性法律,如:罗马尼亚、蒙古、联邦德国颁布“狩猎法”,苏联颁布“动物界保护和利用法”,泰国颁布“野生动物保存保护法”,匈牙利颁布“森林和野生动物法”,日本颁布“鸟兽保护和狩猎法”,澳大利亚颁布“国家公园和野生动物法”。有的国家还制定了一部分野生动物或特定野生动物的专门法律,如:美国制定有“濒危物种法”,“海洋哺乳动物保护法”、“迁徙鸟类保护法”、“海豹保护法”、“鲸类保护法”、“秃鹰和金鹰保护法”,澳大利亚制定“鲸类保护法”

Research on Ammonia Emission Inventory in Fujian Province [PDF]

open access: yes, 2016
近年来,随着福建地区经济快速发展,城市化进度不断加快,环境与经济发展的矛盾日益突出,大气灰霾污染频繁发生,空气质量和能见度下降。氨是大气霾污染生成的促进剂,对大气污染有着直接和间接的影响。本研究建立了福建省人为源氨排放清单,分析氨的排放特征和时空分布,预测未来氨排放水平,探讨氨排放与氨监测和颗粒物离子的关系,为该地区空气质量改善提供了重要的基础数据。 首先,本研究以2013年为基准年,基于排放因子法建立了福建省人为源氨排放清单。研究显示,2013年福建地区人为源氨总排放量是25.24万吨 ...

Detecting mass mortality events in wildlife populations

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Reports in the literature of mass mortality events (MMEs) involving diverse animal taxa are increasing. Yet, many likely go unobserved due to imperfect detection and infrequent sampling. MMEs involving small, cryptic species, for instance, can be difficult to detect even during the event, and degradation and scavenging of carcasses can make ...

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

Extent of threats to marine fish from the online aquarium trade in the United States

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
The global marine aquarium hobby is a multibillion‐dollar industry, largely driven by demand from the United States. Much of this trade occurs online. We web scraped 4 major US‐based e‐commerce platforms selling marine aquarium fish to determine the retail price and source (wild capture, aquaculture, or both) of 13 families of ray‐finned marine fish ...
