An international research team led by the universities of Göttingen and Hohenheim in Germany has gained new insights into how the interaction of birds, bees and bats significantly increases the quantity and quality of macadamia nuts. Furthermore, the effectiveness of their ecosystem services—pollination and biological pest control—depends on the altitude of the area and whether it provides natural habitats.
