Default Pollinator diversity improves fruit set in coffee.

This pdf is from 2008 but still valid. New information has been coming out recently and I am looking to post a few more papers on pollinator diversity and site management accessments. This is a good read to start with.

Pollination is an ecological process that provides important services to humans. Pollination service in agroecosystems depends on several factors, including the land management systems used by farmers.

Here we focused on the effects of insect pollinator diversity on coffee fruit production along a gradient of management systems in central Veracruz, Mexico.
The gradient ranged from low environmental impact management systems (the native forest is not completely removed) to high environmental impact management systems (the native forest is completely removed). We hypothesized that pollinator diversity should be higher in low-impact systems.

Then, if fruit production is positively related to
pollinator diversity, plantations with low-impact management systems should display higher fruit production than plantations with high-impact management systems. We used observational and experimental data to test this hypothesis.

Our results indicated that low-impact management systems
have higher species richness and relative diversity (measured with the Shannon-Wiener diversity index) of pollinators than high-impact management systems.

In all cases, fruit production was positively related with species richness and diversity of pollinators. Moreover, fruit production was higher in low-impact than in high-impact management systems.

These results suggest that the diversity of insect pollinators
can be influenced by the management system applied by farmers, and that such effects may have strong consequences on coffee fruit production.

Great find, Gloria. Thank you for sharing it.

This is the kind of evidence that can help convince people who do not support our goals for preserving biodiversity* for simple altruistic reasons.

* In my mind, I mean "highly functioning, non-degraded habitats of indigenous plants and animals" not just a mix of various plants.
