It is not like in the Americas or Africa, where the animals one is researching are at least somewhat easier to find, and (funds permitting) researchers just have to follow the wild boar herds in a helicopter and shoot tranquilizer darts to get hold of them.
不像在美洲、非洲大陸，找研究對象起碼比較容易，在經費許可下，工作人員可以在直升機上追著動物群打麻醉槍。
