Wild insect diversity increases inter-annual stability in global crop pollinator communities

Deepa Senapathi, Jochen Fründ, Matthias Albrecht, Michael P. D. Garratt et autres

While an increasing number of studies indicate that the range, diversity and abundance of many wild pollinators has declined, the global area of pollinator-dependent crops has significantly increased over the last few decades. Crop pollination studies to date have mainly focused on …

A global synthesis reveals biodiversity-mediated benefits for crop production

Matteo Dainese, Emily A. Martin, Marcelo A. Aizen, Matthias Albrecht et autres

Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related ecosystem services can be maintained by a few dominant species or rely on high richness remains unclear. Using a global database from 89 studies …

Impacts of fire history in a semi-arid woodland savanna

Dave F. Joubert, Caroline Stolter, Kristin M. Krewenka, Elise N. Nghalipo et autres

Fire is known to be an important element shaping semi-arid ecosystems.Within SASSCAL we conducted several projects in the woodland savanna of the Waterberg Plateau Park to gain a better understanding of the impact of fi re on ecosystem properties and processes (soil …

Correction: Corrigendum: Delivery of crop pollination services is an insufficient argument for wild pollinator conservation

David Kleijn, Rachael Winfree, Ígnasi Bartomeus, Luísa G. Carvalheiro et autres

Nature Communications 6: Article number: 7414 (2015); Published: 16 June 2015; Updated: 18 February 2016. The authors inadvertently omitted Kimiora L. Ward, who managed and contributed data, from the author list. This has now been corrected in both the PDF and HTML …

EDITOR'S CHOICE: REVIEW: Trait matching of flower visitors and crops predicts fruit set better than trait diversity

Lucas A. Garibaldi, Ígnasi Bartomeus, Riccardo Bommarco, Alexandra‐Maria Klein et autres

Summary Understanding the relationships between trait diversity, species diversity and ecosystem functioning is essential for sustainable management. For functions comprising two trophic levels, trait matching between interacting partners should also drive functioning. However, the predictive ability of trait diversity and matching is …

Delivery of crop pollination services is an insufficient argument for wild pollinator conservation

David Kleijn, Rachael Winfree, Ígnasi Bartomeus, Luísa G. Carvalheiro et autres

There is compelling evidence that more diverse ecosystems deliver greater benefits to people, and these ecosystem services have become a key argument for biodiversity conservation. However, it is unclear how much biodiversity is needed to deliver ecosystem services in a cost-effective way. …

Contribution of insect pollinators to crop yield and quality varies with agricultural intensification

Ígnasi Bartomeus, Simon Geoffrey Potts, Ingolf Steffan‐Dewenter, Bernard E Vaissiere et autres

Background. Up to 75% of crop species benefit at least to some degree from animal pollination for fruit or seed set and yield. However, basic information on the level of pollinator dependence and pollinator contribution to yield is lacking for many crops. …

A global quantitative synthesis of local and landscape effects on wild bee pollinators in agroecosystems

Christina Marie Kennedy, Eric V. Lonsdorf, Maile C. Neel, Neal M. Williams et autres

Bees provide essential pollination services that are potentially affected both by local farm management and the surrounding landscape. To better understand these different factors, we modelled the relative effects of landscape composition (nesting and floral resources within foraging distances), landscape configuration (patch …

Wild Pollinators Enhance Fruit Set of Crops Regardless of Honey Bee Abundance

Lucas A. Garibaldi, Ingolf Steffan‐Dewenter, Rachael Winfree, Marcelo A. Aizen et autres

Honeybees Can't Do It Alone The majority of food crops require pollination to set fruit with the honeybee providing a pollination workhorse, with both feral and managed populations an integral component of crop management (see the Perspective by Tylianakis , published online …
