Following the recent discovery of rodent pollination in the Pagoda lily, Whiteheadia bifolia (Hyacinthaceae) in South Africa, now the Cape rock elephant-shrew, Elephantulus edwardii (Macroscelidea, Afrotheria) is reported as an additional pollinator. Elephant-shrews, live-trapped near W. bifolia plants, were released in two terraria, containing the plants. The animals licked nectar with their long and slender tongues while being dusted with pollen and touching the stigmas of the flowers with their long and flexible noses. The captured elephant-shrews had W. bifolia pollen in their faeces, likely as a result of grooming their fur as they visited the flowers without eating or destroying them. The animals mostly preferred nectar over other food. This is the first record of pollination and nectar consumption in the primarily insectivorous E. edwardii, contributing to the very sparse knowledge about the behaviour of this unique clade of African mammals, as well as pollination by small mammals.
继最近在南非发现白叶塔黄(风信子科)存在啮齿动物传粉现象后,现在又有报道称,南非岩象鼩(非洲兽总目,象鼩目)也是一种传粉者。在靠近白叶塔黄植株处活捉的象鼩被放入两个装有该植物的饲养箱中。这些动物用又长又细的舌头舔食花蜜,身上沾满花粉,并用又长又灵活的鼻子触碰花朵的柱头。捕获的象鼩粪便中含有白叶塔黄的花粉,这可能是它们在拜访花朵时梳理毛发的结果,它们并未食用或破坏花朵。这些动物大多更喜欢花蜜而非其他食物。这是主要食虫的南非岩象鼩传粉和取食花蜜的首次记录,有助于填补关于这种独特的非洲哺乳动物类群行为以及小型哺乳动物传粉方面非常稀少的知识空白。
