Interacting with wildlife tourism increases activity of white sharks.

ABSTRACT: Anthropogenic activities are dramatically changing marine ecosystems. Wildlife tourism is one of the fastest growing sectors of the tourism industry and has the potential to modify the natural environment and behaviour of the species it targets. Here, we used a novel method to assess the effects of wildlife tourism on the activity of white sharks (Carcharodon carcharias). High frequency three-axis acceleration loggers were deployed on ten white sharks for a total of ~9 days. A combination of multivariate and univariate analysis revealed that the increased number of strong accelerations and vertical movements when sharks are interacting with cage-diving operators result in an overall dynamic body acceleration (ODBA) ~61% higher compared with other times when sharks are present in the area where cage-diving occurs. Since ODBA is considered a proxy of metabolic rate, interacting with cage-divers is probably more costly than are normal behaviours of white sharks at the Neptune Islands. However, the overall impact of cage-diving might be small if interactions with individual sharks are infrequent. This study suggests wildlife tourism changes the instantaneous activity levels of white sharks, and calls for an understanding of the frequency of shark-tourism interactions to appreciate the net impact of ecotourism on this species' fitness.

Project description:This study investigated the attitudes of the people living in three adjacent communities close to the Bomfobiri wildlife sanctuary in Ghana concerning the observation of the cultural, seasonal closures of hunting. The cognitive and motivational approaches to attitude theory in wildlife management guided, under the phenomenology method, the collection of qualitative data on the importance of the seasonal closure of hunting and its implementation challenges. This inquiry was deemed crucial to improving the disjointed relationship between park management and local communities that often make wildlife conservation and tourism difficult at the Bomfobiri Wildlife Sanctuary. Forty-five key wildlife stakeholders, including park officers, traditional authorities, elderly residents, and bushmeat traders, were purposively selected with some interviewed personally and others engaged in focus group discussions. Despite a more significant number of stakeholders admitting the importance of the seasonal closure of hunting, some challenges impeded its implementation. These included the absence of alternative arrangements to support hunters during the period for the annual closure of hunting; lack of proper sensitisation and education on the hunting ban; absence of transparency in the equitable sharing of proceeds from wildlife tourism at the Bomfobiri Wildlife Sanctuary among park officers (Government) and the traditional authorities; the booming bushmeat business and the fear of losing customers after the fallow period; and purported corruption on the part of park officers, threatening the observation of the seasonal closure of hunting. The study has offered proactive suggestions to the Wildlife Division of the Forestry Commission and mainly to park management at the Bomfobiri Wildlife Sanctuary on how to address these challenges and improve wildlife management and sustainable wildlife tourism potentials in Ghana. Paramount among them is the tactful provision of alternative sources of livelihood and the establishment of enterprises in non-timber forest products as sources of income for hunters during the seasonal hunting ban.
