Abstract
Usui, R. & Funck, C. 2018. Analysing food-derived interactions between tourists and sika deer (Cervus nippon) at Miyajima Island in Hiroshima, Japan: implications for the physical health of deer in an anthropogenic environment. J. Ecotourism 17(1): 67-78. DOI: 10.1080/14724049.2017.1421641
Sika deer (Cervus nippon) on Miyajima Island in Hiroshima, Japan, are accustomed to a human environment and close tourist-deer interactions occur. In 2008, city officials banned deer feeding in response to an increasing number of human-deer conflicts. Nevertheless, this regulation remains ineffective. In this study, food-derived interactions between tourists and deer were analyzed, and a faecal analysis was conducted to examine the effects of potentially beneficial bacteria on the digestive system of deer. Over 64 hours of observation, a total of 397 tourist-deer interactions were recorded. Most interactions involved tourists’ food purchases from street stalls (49.6 %). The initiator of each interaction was recorded for 267 events (67.3 %), and it was found that deer initiated nearly twice as many interactions as tourists (tourists: 93 events; deer: 174 events). However, feeding occurred in only 11.5 % of deer-initiated interactions, while feeding occurred in 50.5 % of tourist-initiated interactions. The analysis of gastrointestinal bacterial community compositions showed that deer in the tourism district possessed a lower portion of the order Lactobacellales than deer in the non-tourism district. This was presumably due to different food sources, indicating that the human-influenced environment, of which feeding is one element, could affect the physical health of the deer.

ノート
- 観光客とシカの相互作用を分析するとともに，糞を用いた細菌叢の分析を行った．
- 観察の結果，観光客から始まる相互作用と比べて，シカから始まる相互作用の方が頻度にして2倍多かった．ただし，観光客から始まった場合の方が餌の獲得の割合が高かった．
- 糞を用いた細菌叢の分析の結果，観光客がいない場所のシカに比べて，観光客がいる場所の個体では乳酸菌が少なかった．人間の影響がシカの健康に影響を与える可能性が示唆された．
