New perspectives on trophic guilds of arthropodivorous bats in North

In the absence of field data that document these various proposed criteria for guild assignments, placement of many bat species into guilds has been done according to phylogenetic affinity (Denzinger and Schnitzler 2013). Features used for this are based mainly on morphological traits and echolocati ...
