摘      要：Background:Land‑use change frequently affects faunistic populations and *** achieve successful conservation strategies,we need suitable information about species distribution and the causes of extinction *** amphibian species depend on riparian vegetation to complete their life *** 41%of amphibian species are globally threatened,and accurate estimations of population size,species richness and the identification of critical habitats are urgently needed *** evaluate the magnitude of changes in species richness and demography,estimations that include detection probability are *** this study,we employed multi‑species occupancy models to estimate detection probability and the effect of land cover type(i.e.,cropland,artificial pasture,secondary and mature forest)in a 500‑m radius on the occupancy probability and richness of diurnal amphibians in 60 riparian zones in the state of Michoacán in central ***,we evaluated the potential of the endemic salamander Ambystoma ordinarium as a flagship species for the conservation of other native amphibian ***:We registered a total of 20 amphibian species in the diurnal assemblage,of which 10 species are considered at risk of *** found that cropland was the most important land‑use type for explaining amphibian distribu‑tion in riparian zones,with negative effects on most amphibian *** found no differences in species richness between zones with and without *** riparian zones occupied by ***,however,we found a higher number of species at risk of ***:Our findings showed negative effects of croplands on the distribution of most amphibian *** riparian zones are important for the maintenance of native diurnal amphibian communities and *** can act as a flagship species for the conservation of threatened amphibian species.
