野生动物资源犯罪是资源类犯罪中为数较多的组成部分,其危害性日益彰显。为对有力打击此类犯罪提供较为完备的法律保障,完善野生动物资源刑事法律责任制度成为严厉打击此类犯罪行为,有效保护野生动物资源所必须。我国制定关于野生动物保护的法律、法规起步较晚,基础较差。通过对中俄野生动物资源刑事责任法律制度的比较,并借鉴俄罗斯联邦刑法典中对野生动物资源犯罪的规定之优点,完善中国刑法对此类犯罪刑事责任制度的相关规定,应增设有关罪名,对现有罪名罪状进行补充修改,完善加重责任条款。  相似文献

The CRAVED model has been used to understand theft variation in a whole host of hot products, including wildlife. Past research, however, has only applied the model at either the theft or illicit market stage to understand why particular products are stolen in high numbers. The CRAVED model has yet to be applied to the trafficking stage of hot products smuggled between illicit markets and, therefore, its applicability at this particular stage remains unknown. Using secondary data from the Los Pozos wildlife market in Santa Cruz, Bolivia, this study applies the CRAVED model to explain why parrot species are trafficked between illicit markets in Bolivia. This research finds that species that are more “available” and less “valuable” are more likely to be trafficked between illicit markets, suggesting that variation at the trafficking stage of the parrot trade can be explained by nearly the same CRAVED concepts as they do at the poaching stage. This study also finds that one-quarter of parrots in the Los Pozos market are trafficked to other cities, of which 99% are to the city of Cochabamba. These findings suggest that shutting down illicit markets and patrolling major roadways between cities can substantially reduce the illegal parrot trade.  相似文献

Lesions of the digestive tract due to barotrauma resulting from compressed air application are not common, are rarely lethal, and largely affect the sigmoid and descending colon. Moreover, their pathogenic mechanism is a topic of discussion because these lesions have multiple characteristics. Here, the authors describe an autoptic case of death from lesions of the ascending and transverse segments, with perforations and bleeding suffusions as well as ischemic areas covered the colonic wall that was extremely thinned, congested, and hemorrhagic, with considerable flattening leading to disappearance of the mucosal folds and with numerous petechial hemorrhages. The pathological framework of lung congestion made it possible to identify the mechanism responsible for this death as depletion of the heart's pumping function, which contributed significantly to the acute respiratory failure due to respiratory distress as well as to reduced mobility of the diaphragm due to intestinal distension. Acute heart failure played an important role in this death.  相似文献

The current study analyses seizures made at US ports of entry between 2003 and 2013, with the aim to identify concentrations of illegal wildlife imports into the United States. Findings show that 94% of species seized belong to six groups – mammals, molluscs, birds, reptiles, fish and coral – with mammals and reptiles making up more than half of all seizure incidents. Additionally, most seized wildlife is imported as leather products, medicinal products and as meat. The majority of seizures emanate from six countries, and illegal wildlife is primarily brought to the US via airline baggage. Temporal trends of wildlife seizures point to increases in the seizures of all groups of species, with the exception of birds. Based on these findings, we recommend using situational crime prevention techniques at US ports of entry to reduce opportunities that enable this trade.  相似文献

ABSTRACT

The foundation of current legal protection for animals in China is based on the principle of “rational utilization.” This utilitarian attitude supports the exploitation of animals through the legal means of resource management. However, through a process of public education and the construction of recent legislation, attitudes toward animals are rapidly changing in China. After the introduction of the concept of animal welfare in China in 1989, preliminary socioeconomic events such as early laboratory animal science, animal cruelty reports, pet ownership, engagement in international trade, and the severe acute respiratory syndrom (SARS) epidemic helped spur a trend away from a purely utilitarian attitude toward more positive associations with animals among members of the Chinese public. This phenomenon will be analyzed through the actions of non-governmental organizations, the media, academia, and international business to influence education and the development of legislation to promote animal protection practices. In addition, recent events will be used to illustrate political realities in China that impede the full promotion of animal welfare protection.  相似文献

实验性轻度病毒性心肌炎的组织病理学观察   总被引:2,自引:0,他引:2  
为探索轻度病毒性心肌炎的法医病理学诊断方法,以适量 Coxsackie B3病毒感染 Balb/c小鼠造成小鼠轻度病毒性心肌炎,对病鼠的心、肝、脾、肺、肾进行常规病理学检查。结果发现,心肌炎小鼠的各器官出现不同程度的病理改变。实验提示,病毒性心肌炎是一类多器官病变的疾病;对多器官进行病理学观察和综合分析是轻度病毒性心肌炎的组织病理学诊断的有效方法之一。  相似文献

中国畜牧业可持续发展面临动物疫病多发复发、动物生产性能和产品质量安全性下降、人畜共患病的传染造成人员伤亡和社会的恐慌、大量减少畜禽产品消费并严重降低产品价格等问题的制约。这些制约问题发生的原因为:不当低价政策压缩养殖生产的赢利度,加上落后的动物福利观念,使农民只能低水平生产,长期忽视养殖硬件、环境和环保建设。该文认为,通过加强硬件投入和开展福利养殖,可阻止动物疫病流行、提高动物生产性能和产品质量安全性、最终提高社会消费信心。并就促进中国畜牧业可持续发展的经济政策、人文观念和养殖生产条件方式等方面提出系列措施和建议。  相似文献

Parrots are amongst the most beautiful and intelligent bird species in the world. They have been coveted as pets for centuries, particularly in the neo-tropics where they are heavily populated. Unfortunately, this has led to dramatic increases in parrot poaching over the last few decades, making parrots the most threatened bird species in the world. Despite laws against parrot poaching throughout the neo-tropics, the illegal trade continues while parrot populations further decline. This article reviews the literature on the players in the illegal parrot trade (i.e. poachers, itinerant fences, and market sellers), how poaching is largely committed, and which species are more at risk of becoming poached.  相似文献

Abstract

This paper focuses on the ability of local communities to make effective use of private legal tools as a means of assuring sustainable wildlife use. Using recent legal developments in Kenya as a case study, the paper examines a series of contracts entered into between local communities in the Samburu District and tour operators wishing to bring wildlife “photo safaris”; onto Samburu lands. These contracts, typically referred to as “Eco‐tourism contracts,”; are designed simply to allow tour operators to lead tour groups through community property without trespass. The authors argue that to achieve their true potential, these contracts must be treated, in essence, as “wildlife easements,”; or “eco‐easements,”; that can become publicly‐recorded mutual conservation commitments, and as such must incorporate conservation principles with a focus on environmental impact and wildlife management. Moreover, these contracts must be linked both conceptually and financially to the communities’ governance structure and to its broader conservation efforts.  相似文献
