Patterns in Gray Wolf Pup Survival and Recruitment in Northern Minnesota
… dynamics. Because estimating gray wolf pup survival is challenging, our understanding of pup survival and the factors influencing survival and recruitment is limited. I used a combination of litter counts and video observations from a large remote camera array to estimate annual wolf pup …

Influences of social and habitat features on selection and use of breeding habitat and pup survival in South American fur seals
… seals in Peru; and I examined how mortality of pups was influenced by habitat features, female behavior, and the social environment on the beach.</p><p>Arctocephalus australis in Peru have declined gradually over the past decade, and declined dramatically (72%) due to low food availability …

Solitary, reproductive, and parental behavior of maned wolves (Chrysocyon brachyurus)
… testing many parental care theories. High pup mortality, often caused by females abandoning or cannibalizing newborns, plagued early captive breeding efforts. At the time, the custom at most zoos was to remove the male prior to birth for fear that he would harm pups or that his presence …

The use of monoclonal antibodies specific for rat relaxin to study the physiological roles of relaxin in pregnant rats
… exhibited prolonged delivery and reduced pup survival at birth compared to controls.

Cataract formation in young rats as a consequence of maternal diets containing excess phenylalanine and low in tryptophan and/or vitamin E
… amino acids resulted in decreased fertility, pup survival, and increased diuresis. Supplementation with vitamin E (40.0mg/lOOg) alone prevented these effects. Urinary excretions of keto acid (phenylpyruvate), nitrogen, urea, and creatinine were examined during the 7-l4th days of gestation. …

Roles of Group B Streptococcal membrane proteins in virulence and protection
… challenge. In addition to improving fetal survival in immunized dams, maternally-derived GBS-NN-specific antibodies were detected in full-term pups and contributed to improved pup survival following intranasal GBS challenge. Together, the insights gained from this thesis highlight the …

Role of infection and inflammation in a mouse model of preterm labour
… of anti‐inflammatory agents to delay delivery of pups and to improve their survival; and to investigate the role of specific immune cell populations in infection-induced preterm labour. To characterise the inflammatory and immune response to intrauterine infection, CD1 mice received an …

Genetic Dissection of Anthropogenic Impacts on a Declining Antarctic Fur Seal Population
… possibilities: selection acts during the pup life-history stage or the juvenile life-history stage. Studies of other pinnipeds have shown that the highest mortality occurs in the juvenile life-history stage after weaning, suggesting this is the most vulnerable period in many species and …
