    Creator:
    Talent, Larry Gene
    Abstract:
    In 1976 and 1977 I examined three broad problems associated with the recruitment of young mallards, Anas platyrhynchos, in the Prairie Pothole Region of North Dakota. The three problems studied were: the effects of interspecific nest parasitism on production; the chronology and magnitude of total-brood loss during the brood-rearing period;...

    Abstract:
    A study of the phyletic relationships among five species of tragopans and an outgroup, the Blood Pheasant (Ithaginis cruentus), was conducted from 1987 to 1991. Biochemical, behavioral, and external morphologic characteristics were compared. A cladistic approach was used to compare the behavioral, biochemical, and external morphologic data collectively, as different...

  • A comparative study of prenatal behavior ontogeny in altricial and precocial murid rodents

    Creator:
    Robinson, Scott R., 1952-
    Abstract:
    Using techniques that permit the direct observation of fetuses in vivo, prenatal behavioral development was compared among four species in the rodent family Muridae: the Norway rat (Rattus norvegicus), Mongolian gerbil (Meriones unguiculatus), cotton rat (Sigmodon hispidus), and spiny mouse (Acomys cahirinus). Rattus and Meriones bear altricial offspring, as do...
