Body size is an essential variable in many behavioural and physiological studies. Previous methods for body size estimation present two conflicting drawbacks. They either (1) consider variation in only one dimension through linear measurements or (2) they are time and resource consuming, hard to apply in field conditions and/or stressful to the animal. We present a method for estimating body size, an ellipsoid approximation, which requires simple linear measurements and incorporates variation in three dimensions. The method is tested on two species of teleost fish and one species of insect. The amount of variance in mass explained by the proposed method exceeds that of previous reported methods, including the most accurate ones, that usually require expensive digitising procedures and/or stressful handling. |
