Estimating population size for Hawaiian monk seals using haulout data

Autor: Albert L. Harting, Thea C. Johanos, Jason D. Baker

Publikováno v: The Journal of Wildlife Management. 81:1202-1209

Obtaining a range-wide abundance estimate for the Hawaiian monk seal (Neomonachus schauinslandi; monk seal) has formerly not been possible because of data limitation at sites where the only available data are infrequent counts. We describe a new meth

Estimating Hawaiian monk seal range-wide abundance and associated uncertainty

Autor: Charles L. Littnan, Albert L. Harting, Thea C. Johanos, Jason D. Baker

Publikováno v: Endangered Species Research, Vol 31, Pp 317-324 (2016)

The type and quantity of survey data, and consequently, applicable methods for estimating abundance, vary throughout the range of the Endangered Hawaiian monk seal Neomonachus schauinslandi. Here we present a new approach to combine disparate data an

Benefits derived from opportunistic survival-enhancing interventions for the Hawaiian monk seal: the silver BB paradigm

Autor: Charles L. Littnan, Albert L. Harting, Thea C. Johanos

Publikováno v: Endangered Species Research, Vol 25, Iss 1, Pp 89-96 (2014)

The cumulative benefits derived from historic small-scale, opportunistic interventions for the Hawaiian monk seal Monachus schauinslandi were assessed using multiple methods. The analysis focused on interventions undertaken to enhance survival of ind

Body growth in Hawaiian monk seals

Autor: Charles L. Littnan, Thea C. Johanos, Tracy A. Wurth, Jason D. Baker

Publikováno v: Marine Mammal Science. 30:259-271

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. S

ESTIMATING CONTACT RATES OF HAWAIIAN MONK SEALS (NEOMONACHUS SCHAUINSLANDI) USING SOCIAL NETWORK ANALYSIS

Autor: Stacie J. Robinson, Michelle Barbieri, Thea C. Johanos, Albert L. Harting, Charles L. Littnan, Jason D. Baker

Publikováno v: Journal of wildlife diseases. 52(3)

Understanding disease transmission dynamics, which are in part mediated by rates and patterns of social contact, is fundamental to predicting the likelihood, rate of spread, impacts, and mitigation of disease outbreaks in wildlife populations. Contac

Translocation as a tool for conservation of the Hawaiian monk seal

Autor: J.R. Henderson, Thea C. Johanos, Brenda L. Becker, Jason D. Baker, Tracy A. Wurth, Charles L. Littnan

Publikováno v: Biological Conservation. 144:2692-2701

The deteriorating demographic status of the endangered Hawaiian monk seal has motivated renewed and expanded proposals for conservation action, including translocation of seals to improve survival. Over the past three decades, numerous monk seal tran
