摘      要：Eye position varies significantly among taxonomic levels,and this variation is often shaped by ecological and behavioral *** position is often positively associated with interorbital distance where species with broad visualfields possess a large distance between the left and right *** pressures underlying the evolution of the eye position are especially studied in birds and ***,selective pressures underlying the evo-lution of anuran eye position which can be indicated by interorbital distance keep ***,we investigated the effects of ecological(*** type,light availability)and behavioral factors(*** pattern,foraging mobility,and defensive strategy)on variations in interorbital distance among 260 anuran species in *** results showed that variations of the interorbital distance can be significantly predicted by the activity ***-turnal species had larger interorbital distance than both nocturnal and diurnal *** also found that foraging mobility and defensive strategy markedly affected variation of interorbital *** having slower foraging mobility and possessing poison glands had larger interorbital distance than species having faster foraging mobility and possessing non-position *** availability tended to be associated with variation of interorbital distance,indicating that species living in weak light tended to possess larger interorbital ***,variations of the interorbital space were not associated with habitat type in ***findings suggest that anuran behaviors play key roles in shaping visualfields and eye position,thus affecting the evolution of interorbital distance.
