Tutkimuksessa selvitettiin emohaukien koon vaikutusta m\u00e4din ja poikasten laatuun. Tarkoitusta varten pyydystettiin yhteens\u00e4 26 emo- ja 12 koirashaukea kolmesta pienest\u00e4 etel\u00e4suomalaisesta mets\u00e4j\u00e4rvest\u00e4. Naaraat olivat 22,3-94,5 cm:n ja koiraat 40,0-45,0 cm:n pituisia.

M\u00e4ti haudottiin sihtisaaveissa kontrolloiduissa olosuhteissa. Kuoriutuneista poikasista mitattiin pituus ja kuivamassa, sek\u00e4 13 naaraalta otettiin 50 poikasen er\u00e4 n\u00e4lkiintymiskokeeseen. Emokalan pituudella ja vastakuoriutuneiden poikasten keskim\u00e4\u00e4r\u00e4isell\u00e4 kuivamassalla oli positiivinen tilastollisesti merkitsev\u00e4 riippuvuus.

Emokalan pituuden ja m\u00e4tijyv\u00e4n keskim\u00e4\u00e4r\u00e4isen kuivamassan v\u00e4linen riippuvuus oli yksihuippuinen.
