发酵床对圈养山魈(Mandrillus sphinx)行为的影响
野生动物学报, 2018 2013年12月1日～2014年2月1日,以上海动物园繁殖场内的11只山魈(Mandrillus sphinx)为研究对象,分为2组做发酵床丰容对照实验,实验组山魈4只,对照组山魈7只,分析了发酵床垫料对圈养山魈活动行为比例的影响。发酵床的垫料分别由木屑、米糠、黄土组成,投放比例为5:4:1。结果表明,在有丰容设施时,山魈的休息行为和刻板行为明显减少,摄食和玩耍行为明显增加,与预期结果一致。在对丰容设施的利用上,增加的丰容垫料设施有效地促进了山魈对垫料的利用。实验组山魈的垫料活动行为包括探究、咀嚼 ...

Host location behavior of Aedes albopictus and Empoasca vitis: olfactory and visual effects on their orientation [PDF]
, 2015 在昆虫宿主定位行为中，嗅觉与视觉究竟哪个更为重要至今尚无定论。本研究选择福建地区广泛分布、并且具有重大危害的白纹伊蚊（Aedesalbopictus）和假眼小绿叶蝉（Empoascavitis）为研究对象，以干扰害虫对宿主生物的定向通讯行为为研究思路，整合形态学、分子生物学和行为学方法试图揭示嗅觉和视觉在昆虫宿主定位行为中的作用。以期深入理解昆虫的宿主定位行为机制并为害虫防治提供新思路。研究结果如下： （1）应用RACE技术获得白纹伊蚊嗅觉共受体基因（AalbOrco）全长编码序列 ...

Regulatory compliance and support for altered management of the exotic pet trade
Conservation Biology, EarlyView.Abstract Globally, the exotic pet trade has contributed to species invasion, disease, and animal welfare risks. Although scientists have advocated for increased trade regulation, the success of management and regulatory efforts depends on compliance by participants in the exotic pet trade. We used a regulatory compliance framework to investigate exotic

On the Reporting System of Administrative Illegal Activities——Based on the Relevant Experience of Taiwan [PDF]
, 2016 行政违法行为举报制度，是指行政机关依照相关法律法规，针对个人或组织对他人行政违法行为的举报，依法进行审查、受理和处理，并对举报人进行保护和奖励的制度集合。该制度设置的主要目的在于缓解当前行政机关面临的执法困境、提供公众参与社会管理的有效途径，其作为一项承载着众多希冀的制度，学者们对它的研究还比较少。本文旨在阐述行政违法行为举报制度的基本理论，并以台湾地区的相关经验为参照，分析该制度在大陆地区立法和实践中存在的问题，继而提出相应的解决思路。 文章分为引言、正文、结语三个部分，其中正文部分共分为三章 ...

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, EarlyView.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Research on the Influence of IWOM on the Purchase Intention of Urban White Collar Women——Take Online Clothing Purchase for Example [PDF]
, 2016 电子商务模式的不断深入逐渐改变了现代人的消费行为和消费习惯。中国电子商务研究中心调查显示，2015上半年中国电子商务交易额7.63万亿元，同比增长30.4%，其中网络零售市场交易规模达16140亿元，相比2014年上半年同比增长48.7%。相比于过去，人们如今更愿意在网络上搜寻需求的商品，消费者网络购买意愿的影响因素逐渐成为近几年研究的热点。国内外学者已有大量关于传统口碑影响下消费者购买意愿的研究成果，但在网络口碑这一环境下，有关消费者购买意愿影响因素的研究仍有空白。例如对口碑接收者的细分程度不够 ...

Informal supply chains of wild meat from rural Amazonia and food security in an urban center
Conservation Biology, EarlyView.Abstract Iquitos, the most populated city in the Peruvian Amazon, is a hub in the regional supply chain of wild meat and supplies urban consumers. Studies on wild meat consumption have focused primarily on markets, limiting the scope of species considered to those that are economically valuable and potential inferences from those data.

A more‐than‐human political ecology of Indonesian songbird trade
Conservation Biology, EarlyView.Abstract Since its inception, conservation science has considered wildlife trade a problem. In focusing on conservation outcomes, conservationists almost completely ignore the welfare of traded animals and plants and the harms they endure. We developed a political ecology approach that incorporates the interconnectedness of people with animals and ...
