When it comes to predicting the abundance of a species, body size appears to be a fundamental and repeatable predictor, with smaller organisms occurring in greater numbers than larger ones. The caveat, known as Bermann’s Rule, is that in polar regions larger bodied organisms predominate. Other factors that influence species abundance include light availability, food availability, competition and predation.
