Four harpactorine species of assassin bugs, Coronus contrarius Reuter, Rhynocoris annulatus （Linnaeus）, Rhynocoris rubrogularis （Horvath）, and Vachiria deserta （Becker）, are newly recorded from Iran.

The results showed that the distribution area of Korean musk deer (Moschus moschiferus parvipes) was sharply decreased from 1950s to 1999 in South Korea. Due to the road and forest road construction in the habitat of Korean musk deer, the musk deer habitats were fragmented and lost. And the illegal capture for economic benefits was the main reason of decreases in number of indi-viduals and habitats of this species. Forest roads in high elevation area were also used as the passages for illegal captures. For the conservation and protection of Korean musk deer, strict regulation of illegal capture is urgently needed.展开更多

In Nepal, it is distributed largely in isolated patches of alpine grasslands of 3,000-5,000 m elevation. Although it is reported from 27 northernmost districts of Nepal, the local distribution pattern of this species is largely unknown.Furthermore, the collection system and local management regime of this species are not well documented. We conducted a field survey at Dhorpatan Hunting Reserve(DHR) among the different stakeholders in January-June 2012 to assess collection sites, patterns and trends and to understand the management regime. We estimated that about 75 kg of Yarsagumba is collected every year from DHR and the amount has been declining since 2008. To manage the resource, locals have initiated regulating the collection by issuing permits, taxing to the collectors, and monitoring the activities of harvesters with the help of park authorities. The revenue generated at local level from the permits has been used for community developmental activities.展开更多

First, we set forth a basic ecological-economic model of a predator-prey-hunting system in which both the predator and prey have use(flow) and non-use(stock) value and when the predator can inflict transboundary damages. We then use new data from the US Mountain West to show how a particular feedback approach—linear parameter-varying(LPV) control—can be utilized in this context. Our LPV model is able to quantify the cost of managing disturbances that inevitably arise as a manager tries to keep the actual path of the system "close" to its optimum. The results suggest management strategies in mountain ecosystems that feature large, mammalian carnivores.展开更多

Thus the paper aims to examine rural tourism and hunting tourism in particular in order to evaluate their development as a lucrative type of investment, while considering the including promotional activities. Certain disadvantages and problems that Serbian hunting tourism has been facing as well as the directions for their solution are addressed in the paper.展开更多
