Body growth in Hawaiian monk seals
Body length and axillary girth measurements of more than 600 free-ranging Hawaiian monk seals from 1 to 20 yr old were analyzed. Comparison of fitted von Bertalanffy growth models confirmed there is no evidence of sexual dimorphism in this species. Substantial differences in growth patterns were detected among seven subpopulations representing the species entire geographic range. The age at whi...

متن کاملTestosterone response to a gonadotrophin-releasing hormone agonist in Hawaiian monk seals (Monachus schauinslandi).
Adult male Hawaiian monk seals were administered a gonadotrophin-releasing hormone (GnRH) agonist to determine its effectiveness in reducing the testicular production of testosterone. Blood samples were collected from four treated seals and two control seals at weekly intervals for 10 weeks and again at the beginning of the following breeding season. The GnRH-agonist had an initial, brief, stim...
متن کاملInitial Defecation Time and Rate of Passage of Digesta in Adult Hawaiian Monk Seals , Monachus schauinslandi
In an effort to gain a better understanding of the digestive physiology of the Hawaiian monk seal, Monachus schauinslandi, we measured the initial defecation time and rate of digesta passage using chromic oxide (Cr2O3) and frozen corn kernels as markers. IDT ranged from 9.5 to 19 h (mean 14 + 4.8 h), which was a longer period of time than that reported for any other pinniped. Rate of digesta pa...
متن کاملAn integrated approach for assessing translocation as an effective conservation tool for Hawaiian monk seals
For threatened and endangered species, translocations have been widely used to mitigate multiple sources of mortality that threaten population recovery. Although numerous Hawaiian monk seals Neomonachus schauinslandi have been translocated for a variety of purposes, few monk seal translocations have addressed the problem of prey limitation. To assess the efficacy of using translocations to miti...
