Abstract
    In the northern Baltic a negative correlation has repeatedly been observed between the abundances of Pontoporeia (P. Affinis and P. Femorata) and Macoma baltica. The various views on the factors involved are discussed and predation on young Macoma by Pontoporeia, doubted in a recent paper by Ankar, is considered to offer the most likely explanation.
