Cacao flower visitation: Low pollen deposition, low fruit set and dominance of herbivores
Pollination of native cacao is surprisingly understudied, even though the process is crucial for the global chocolate production. In an understudied peruvian region, we found herbivores as dominant flower visitors, and low pollen deposition.Fruit set was low when flowers were pollinated naturally (2%), but also manually (7%). Our findings highlight the

Complex landscapes stabilize farm bird communities and their expected ecosystem services
Our results suggest that farmers can effectively manage their farms to harness ecosystem services from birds through farm diversification. Disservices provided by birds, however, appear to be most negatively impacted by landscape‐level complexity. Thus, greater incentives for farmers to increase semi‐natural cover at the landscape scale are likely ...
