Focus: Bats and Ecosystem Services 
 
Bats contribute more than most people know to the world's eco-systems and a healthy environment. Bats, in fact, are vital to the restoration and enrichment of our eco-systems, including rainforests and other key ecological habitats. Bats also contribute to human health and well-being by performing essential eco-services such as pollination, seed dispersal and insect control.  
 
A wealth of food and drinks, as well as medicines, come to us through the efforts of numerous bat species. The durian flower, for example, which yields a popular fruit worth more than $230 million annually in Southeast Asia, would not be able to produce its delicious fruit if flying foxes did not pollinate the lovely durian at dusk. 
 
Bats also pollinate wild varieties of bananas. Although seedless and currently not dependent on bats, the commercial bananas we enjoy today co-evolved with bats over thousands of years. Since a single disease could devastate a global banana crop, bats' role in pollinating and dispersing the seeds of this ubiquitous fruit remain important. In a nutshell, fruit bats could keep bananas from disappearing from your favorite market sometime in the near future.  
 
Many of the world's most valuable crop plants rely, as well, on bats: avocados, balsa wood, breadfruit, cashews, carobs, cloves, dates, figs, mangoes and peaches, to name just a few. More than 450 economically significant plant species are known to depend on bats - and the list in fact may be even longer. Bats pollinate and disperse the seeds of more than 110 plant species used to produce food and drinks and 72 plant species utilized to produce medicines. Bats also perform eco-services for 66 plant species that produce timber, 29 used to fabricate fiber and cordage, 25 needed to create dyes, 19 that make tannins and 11 that render animal feed.*

More than 1,200 species of bats comprise nearly a quarter of all mammals, and their ecological services are essential to human economies and the health of whole ecosystems worldwide. Guest author Dr Merlin Tuttle looks at the ecosystem services that bats provide us.
