Despite the interventions from government and Non Governmental Organization to reduce or divert the attention of rural people from the wild by providing alternative livelihood, the level of hunting either remains the same or kept on increasing. However, there is need to categorize and understand the types of hunters in different locality for better design and management of whatever alternative to be provided. The study assessed hunters’ types and their income made from hunting in Afi, Mbe and the Okwango Division of the National park and the rate of poaching activities. The snowball sampling was adopted for gathering data. A descriptive and inferential statistical tool was used to analyze the data collected. The respondents were interviewed with a view to obtaining information on the regularity of their hunting activities, the income made per month and reasons why they hunt and also their views on best alternative. Results revealed that majority of the respondent fall within the age of less than or equal to 40 years with primary and secondary school qualification in which are married with 3 - 12 children. Consequent to this fact hunting activities is effective and prevailing. It further revealed that despite numerous conservation efforts in these areas, poaching activities still prevail owing to the fact that the income made from poaching is much better than the alternative provided for hunters. Furthermore, the assessment also revealed that there are different types of hunters and this makes their income varies greatly. Thus, there are fulltime or core hunters (36.9%), occasional hunters (58.3%), Holiday hunters (2.9%) and social hunters (1.9%). It is therefore paramount to have a better view and understanding of the target group (Poachers) for better alternative and implementation.展开更多

This is how the colonization of the Arctic began. The domestic dog appeared in this region about 25 - 30 thousand years ago as a result of the severe climatic conditions in which both hunting tribes and the ancestors of the domestic dog had to live. A wolf is a predator, an able hunter. Therefore, most likely wolves were originally trained to hunt with humans—the leaders of the hunting pack. Thus, in northeast Asia, there was a direct relationship between man’s colonization of the Arctic, the appearance of the hunting dog, and a decrease in the number of mammoth, bison, and other large animals in the region, as a result of hunting when whole herds were killed.展开更多

Methods: PCR was executed on DNA extracted from 77 tick pools to detect Anaplasma phagocytophilum, Bartonella spp., Borrelia burgdorferi sensu lato, Coxiella burnetii and Rickettsia spp. Results: A total of 432 ticks were collected: 30(6.94%) Haemaphysalis punctata, 72(16.7%) Dermacentor marginatus and 330(76.38%) Ixodes ricinus. For each animal one or two pools of 3 ticks of the same species was constituted. Seventy-seven tick pools were examined by PCR: 58(75.32%) resulted infected and among them 14(18.18%) showed co-infections. In particular, 29(37.66%) pools were positive for Bartonella spp., 23(29.87%) for Anaplasma phagocytophilum, 16(20.78%) for Rickettsia spp., and 5(6.49%) for Borrelia burgdorferi s.l. All samples were negative for Coxiella burnetii. Conclusions: The results demonstrate the presence of several zoonotic tick-borne pathogens in the studied area, and underline the risk of exposure to infections for hunters not only during the outdoor activity, but also when they manipulate hunted animals infested by infected ticks.展开更多
