Delivery of crop pollination services is an insufficient argument for wild pollinator conservation
It is shown that, while the contribution of wild bees to crop production is significant, service delivery is restricted to a limited subset of all known bee species, suggesting that cost-effective management strategies to promote crop pollination should target a different set of species than management Strategies to promote threatened bees.
Creating patches of native flowers facilitates crop pollination in large agricultural fields: mango as a case study
The results show that the presence of small patches of native flowers within large farms can increase pollinator-dependent crop production if combined with preservation of remaining fragments of natural habitat and judicious use of pesticides.
Natural and within-farmland biodiversity enhances crop productivity.
It was found that the presence of weeds allowed pollinators to persist within sunflower fields, maximizing the benefits of the remaining patches of natural habitat to productivity of this large-scale crop.
Valuing Insect Pollination Services with Cost of Replacement
Replacement costs are presented as a more accurate value estimate of insect pollination as an ecosystem service, and pollination services are valued significantly higher than current market prices for commercial pollination, although lower than traditional proportional estimates.
Mutually beneficial pollinator diversity and crop yield outcomes in small and large farms
This study quantifies to what degree enhancing pollinator density and richness can improve yields on 344 fields from 33 pollinator-dependent crop systems in small and large farms from Africa, Asia, and Latin America.
Putting plant resistance traits on the map: a test of the idea that plants are better defended at lower latitudes.
The results do not support the hypothesis that tropical plants have higher levels of resistance traits than do plants from higher latitudes, and if anything, plants haveHigher resistance toward the poles.
Correlations between physical and chemical defences in plants: tradeoffs, syndromes, or just many different ways to skin a herbivorous cat?
It is suggested that a lack of consistent defence syndromes may be adaptive, resulting from selective pressure to deploy a different combination of defences to coexisting species.
Pollination services decline with distance from natural habitat even in biodiversity‐rich areas
This study provides one of the first examples of marked pollination limitation in farms surrounded by well-protected natural habitat and contributes to a growing body of studies that reveal that making farmland more suitable for pollinators benefits both agriculture and nature conservation.
Gall‐forming insect species richness along a non‐scleromorphic vegetation rainfall gradient in South Africa: The importance of plant community composition
Plant community composition should be considered when attempting to explain gall-forming insect species richness patterns, as galling insects may preferentially select those plant species with characteristics such as chemical toxicity, mechanical strength, degree of lignification or longevity that can be manipulated to benefit the galler.
