do you use echolocation forearms what is the fa and fc of a bat what does fc of bat echolocation mean how to predict echolocation what type of range is the echolocation range for bats why is fa a useful parameter in the study of echolocation how to predict echolocation ranges in bats what model does echolocation use to predict bat numbers why do bats echolocation calls vary significantly what is the range for an echolocation bat why is the forearm variability of a bat important if the range of bat echolocation is not verified, then what does the regression model show? do bats have an echolocation range how to predict bat echolocation frequency which parameter does a linear regression model use to predict a bat what is the r code for echolocation how to estimate bat echolocation which is the difference between fa and fc range in lm model do bats have different call frequency ranges what is the difference between an echolocation range and a normal echolocation range
