What acceleration data from wildlife collars and animal body mass tell us about seed dispersal

open access: yesAnimal Biotelemetry, 2023
Background The seeds of many plant species can be dispersed over long distances in animal fur (epizoochory). Quantifying epizoochory in the wild is, however, challenging, since it is difficult to measure the retention times of seeds in fur.
