Letters: Bee conservation: Key role of managed bees

In their Perspective "Conserving honey bees does not help wildlife" (26 January, p. 392), J. Geldmann and J. P. González-Varo argue that because managed honey bees are an agricultural animal, their crop pollination does not fit the definition of an ecosystem service. This distinction, the authors suggest, is a key step to wild pollinator conservation. This argument highlights a fundamental misinterpretation of the ecology of ecosystem services: Services are delivered to beneficiaries through ecological processes and interactions, not by organisms alone.
