Shared variability of body shape ... describing the correlation and covariance among these interdependence traits in terms of the two interpretable common factor(size and shape) in both sexes. Varijabilnost osobina telesne razvijenosti odraslih mošusnih pataka D. M. Ogah Rezime U ovom istraživanju su analizirani telesna masa i šest osobina telesne razvijenosti – dužina tela, obim grudi, dužina bataka, dužina piska, ukupna dužina noge i krila, na uzorku od 150 nigerijskih autohtonih mošusnih pataka, ženskog i muškog pola, u uzrastu od dvadeset nedelja, koje su gajene u polu-intenzivnim uslovima/sistemu. Ciljevi ispitivanja su bili da se ocene osnovni izvori podeljene varijabilnosti između osobina telsne razvijenosti, da se odrede faktori koji opisuju ove karakteristike i kvanitifikuju razlike između polova u morfometrijskoj veličini i obliku tela odraslih mošusnih pataka. Varijacije u deskriptivnoj statistici su zabeležene između ženki i mužjaka kod skoro svih osobina osim dužine piska. Jačina korelacije se takođe razlikovala između polova. Konformacija tela je pod uticajem zajedničkog i jedinstvenih faktora, u opsegu od 0.671 za dužinu piska do 0.987 dužinu tela. References BAEZA E, MARCHE G., WACRENIER N.
