On the Reconstruction of the Ownership System of Aquatic Wild Animals [PDF]
, 2009 我国现行立法对水生野生动物所有权规定,存在着内涵不明确,外延不周延,立法规范与实践相背离等方面的问题。国外的立法实践可为我国的立法完善提供参考思路;突破传统的物权客体理论需要理念革新;明确界定水生野生动物的所有权具有重要的制度价值。我国对水生野生动物的所有权结构应具有多元性;权利主体的权利行使方式应有所限制。There are many problems on current provisions of ownership system of aquatic wild animals,for its ...

Assessing limits of sustainable seed harvest in wild plant populations
Conservation Biology, EarlyView.Abstract Seed harvesting from wild plant populations is key for ecological restoration, but it may threaten the persistence of the source populations. Consequently, several countries have set guidelines limiting the proportions of harvestable seeds. However, these guidelines are inconsistent and lack a solid empirical basis.

Research on the hunting right [PDF]
, 2013 狩猎自人类的诞生以来，一直是人类生产活动的一种主要方式。到了现代社会，由于生产力的发展，狩猎由生产活动转变为一种商业和娱乐活动。而如何在狩猎活动与野生动物保护之间寻求平衡点成为理论界与实践界面临的一个难题，为此，各国都是努力建构各自的狩猎权法律制度，力求协调好这一矛盾。目前，我国在狩猎权方面的立法仍很不完善，问题较多，也影响到了我国狩猎活动的开展，因此，我国急需完善的狩猎权法律制度。 本论文包含前言，正文，结论三个部分，其中正文分为三章。 本文的第一章为“狩猎权概念之分析”。本章从狩猎权概念的定义 ...

Finding floral and faunal species richness optima among active fire regimes
Conservation Biology, EarlyView.Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

盗割死鲸,该当何罪?——以江苏省“3·16”搁浅抹香鲸事件为例 [PDF]
, 2015 盗割者私闯警戒线盗割近100公斤死鲸肉。私闯警戒线已构成违法行为,盗割死鲸已构成盗窃罪,且违反了动物防疫的法律规定。但从法理上分析,按照法不强人所难和遵循先例的理念并从考虑法经济学上考虑应对其减轻处罚。我国亟待出台《动物福利法 ...

Conservation Biology, EarlyView.Abstract Urgency to save species from extinction has prompted increased investment in law enforcement in protected areas. To date, such law enforcement has largely focused on increasing costs and reducing opportunities for offending. However, these resource‐intensive approaches are not always effective and can contribute to conflict between people and ...

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots
Conservation Biology, EarlyView.Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

Integrative Conservation, Volume 4, Issue 2, Page 205-217, June 2025.Zoo visits significantly influence wildlife preferences, enhancing fondness for a wider range of species and fostering affinity for less popular taxa. The interplay between enclosure and interpretive characteristics proved crucial in driving these changes, highlighting ways to optimize zoo conservation education. ABSTRACT Preferences for animal species

Distribution and Risk Assessment of Perfluorinated Compounds in Jiulong River Watershed-Estuary System [PDF]
, 2016 九龙江是闽南和闽西地区重要的饮用水源和工农业用水水源，但近年来九龙江污染日趋严重，河流生态系统承受着巨大的压力，其中持久性有机污染物(POPs)因其难降解性、生物富集性和高致毒性备受人们关注。全氟化合物(PFCs)是一类碳链上氢原子全部被氟原子取代的有机化合物，由于其良好的疏水、疏油特性，已被广泛应用于多种工业和民用产品中，与人类生产生活密切相关。由于PFCs稳定性极强，目前已在包括水、土壤、大气等环境介质及生物体中大量检出。毒理学研究表明，部分PFCs具有致癌性、肝毒性、神经毒性、生殖毒性、免疫毒性等，
