摘      要：Enhanced vegetation index(EVI)data can be used to identify and define the space in which ungulates practice parturition and encounter *** study explores the use of EVI data to identify landscapes linked to ungulate parturition and predation events across space,time,and environmental *** a case study,we used the moose population(Alces alces)of northern Minnesota in the *** remotely sensed EVI data rasters and global positioning system collar data,we quantified how vegetation phenology and moose movement shaped the births and predation of 52 moose calves from 2013 to 2020 on or adjacent to the Grand Portage Indian *** known sources of predation were American black bears(Ursus americanus,n=22)and gray wolves(Canis lupus,n=28).Satellite-derived data summarizing seasonal landscape features at the local level revealed that landscape heterogeneity use by moose can help to quantitatively identify landscapes of parturition and predation in space and time across large *** phenology proved to be differentiable between adult moose ranges,sites of cow parturition,and sites of calf *** characteristics of each moose group were consistent and tractable based on environment,suggesting that sites of parturition and predation of moose are predictable in space and *** is possible that moose selected specific landscapes for parturition despite risk of increased predation of their calves,which could be an example of anecological trap.This analytical framework can be employed to identify areas for future ungulate research on the impacts of landscape on parturition and predation dynamics.
