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.

It elaborates we must adhere to stabilize and improve the rural basic management systems, give farmers more fully right to protect the land, develop rural land contract management rights transfer, and promote agricultural innovation and industrial organization.展开更多

Objective needs have driven local governments＇ exploration of different modes of financialization, providing samples we can analyze in connection with the next steps in institutional development. The financialization of agricultural land arises naturally from its nature as an asset. Whether one acknowledges the land＇s social security function does not affect its financialization. In institutional rebuilding, the particular character of mortgages on agricultural land should be considered. The mortgage-holder must be a financial organization, not a natural person or an ordinary finn. The person mortgaging the right to operate the land under the contract responsibility system need not have a stable non-agricultural occupation or stable source of income, or the consent of the party issuing the contract. Registration constitutes public notification of the setting up of a mortgage and is also the condition whereby it comes into effect. The mortgage cannot be realized by means of discounting, but compulsory management can be used to subcontractor let the relevant agricultural land. The debt can then be liquidated from this income and the land returned to the mortgagor.展开更多

Additionally, these effects may be indirectly extended to higher trophic levels throughout the entire community. Quercus castanea is an oak species with characteristics of foundation species beyond pre- senting a wide geographical distribution and being a dominant element of Mexican temperate forests. In this study, we analyzed the influence of population （He） and individual （HL） genetic diversity of Q. castanea on its canopy endophagous insect community and associated parasitoids. Specifically, we studied the composition, richness （S） and density of leaf-mining moths （Lepidoptera： Tischeridae, Citheraniidae）, gall-forming wasps （Hymenoptera： Cynipidae）, and canopy parasitoids of Q. castanea. We sampled 120 trees belonging to six populations （20/site） through the previously recognized gradi- ent of genetic diversity. In total, 22 endophagous insect species belonging to three orders （Hymenoptera, Lepidoptera, and Diptera） and 20 parasitoid species belonging to 13 families were identified. In general, we observed that the individual genetic diversity of the host plant （HL） has a significant positive effect on the S and density of the canopy endophagous insect communities. In contrast, He has a significant negative effect on the S of endophagous insects. Additionally, indirect effects of HL were observed, affecting the S and density of parasitoid insects. Our results suggest that genetic variation in foundation species can be one of the most important factors governing the dynamics of tritrophic interactions that involve oaks, herbivores, and parasitoids.展开更多
文摘This paper presents the importance of the development of Serbian rural regions, and analyzes their marketing management potentials. 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.
