Ethiopian wolves discovered consuming nectar as pollinators

In Ethiopia, the behavior of Ethiopian wolves (Canis simensis) has captured the attention of researchers as they exhibit an unexpected activity of consuming nectar from various flowering plants, particularly the red-hot poker plant (Kniphofia foliosa). This behavior was documented by a team from the Ethiopian wolf conservation program during a study in May and June of 2023, where they observed wolves from three different packs engaging in this nectar-feeding behavior for the first time in a scientific context. Typically, these wolves are carnivorous, primarily preying on rodents, making this sweet-tooth behavior a noteworthy deviation from their usual diet. During the study, researchers noted that while some wolves visited a small number of flowers, two individuals indulged in over twenty flowers in a single foraging session. This high frequency of visits suggests that nectar foraging might be a prevalent activity among Ethiopian wolves and hints at their potential role as pollinators in the highland ecosystem. The implications of this nectar-feeding behavior raise intriguing questions about the interactions between carnivorous mammals and flowering plants, suggesting a potential for therophily, or pollination by non-flying mammals, to be more widespread than previously acknowledged. However, it is worth noting that the researchers expressed uncertainty regarding the effectiveness of Ethiopian wolves as pollinators, considering the damaging method some wolves display while extracting nectar, which can involve biting into the flowers. While the wolves may acquire pollen on their muzzles from the flowers, whether this translates into effective pollination remains an open question. This research, published on November 19, 2023, in the journal Ecology, indicates that the role of large carnivores in the ecosystem may involve more complexity than traditionally understood, making this an exciting avenue for future research. The broader ecological implications are significant since up to 87% of flowering plants depend on various pollinators for their reproductive success. The newly discovered interaction between Ethiopian wolves and the red-hot poker flowers emphasizes the need for further investigation into how animal behavior influences plant pollination, particularly in unique environments like the Ethiopian highlands where species interactions may differ from those in lower altitudes. Other species, including various birds and insects, also feed on the nectar of these flowers, providing a diverse pollination landscape, yet the interaction of large carnivores like wolves introduces an unexpected dynamic that could alter the understanding of ecosystem functions in these habitats.
