Winter body condition of moose (Alces alces) in a declining population in northeastern Minnesota.

Assessments of the condition of moose (Alces alces) may be particularly informative to understanding the dynamics of populations and other influential factors. During February-March 2003 to 2005, we assessed the nutritional condition of 79 moose (39 females, 40 males) in northeastern Minnesota by body condition scoring (BCS(F), scale of 0-10); 67 of these by were assessed by ultrasonographic measurements of rump fat (Maxfat), which was used to estimate ingesta-free body fat (IFBF) in all but two of the females. Scores of the BCS(F) were related (r(2)=0.
