I am switching over to pollination studies in temperate fruits; any good book suggestions @StephenBHeard @EntoProf @Ecol_Ent @EntsocAmerica

Well, @JeffOllerton's, of course, but you probably knew that.

More on the technical side

I'd ask Jeff what he recommends, for sure! Or look at what's cited in his book -agreed, it's a high-level summary.

A good starting point is the @IPBES assessment report on pollinators and pollination, which you can easily find online. Insect pollination of crops by John B. Free is the standard text though it's a little out of date now (1993). @naturealexk would be a good person to talk to.
