Socio-ecological preditors of moose body condition across a latitudinal gradient in Sweden
Factors predicting moose body condition in Sweden were investigated by means of dressed weight from shot animals and combining a range of potential explanatory variables from public national databases. There were significant differences between regions, sexes and age-classes with considerable variat...
