| adaptive line transect sampling. | adaptive line transect sampling offers the potential of improved population density estimation efficiency over conventional line transect sampling when populations are spatially clustered. in adaptive sampling, survey effort is increased when areas of high animal density are located, thereby increasing the number of observations. its disadvantage is that the survey effort required is not known in advance. we develop an adaptive line transect methodology that, by varying the degree of adaptation, ... | 2002 | 12495140 |
| a bayesian uncertainty analysis of cetacean demography and bycatch mortality using age-at-death data. | wildlife ecologists and managers are challenged to make the most of sparse information for understanding demography of many species, especially those that are long lived and difficult to observe. for many odontocete (dolphin, porpoise, toothed whale) populations, only fertility and age-at-death data are feasibly obtainable. we describe a bayesian approach for using fertilities and two types of age-at-death data (i.e., age structure of deaths from all mortality sources and age structure of anthro ... | 2008 | 19263888 |
| human exposures to marine brucella isolated from a harbor porpoise - maine, 2012. | on february 10, 2012, the maine center for disease control and prevention (maine cdc) was notified of a positive brucella culture from a harbor porpoise (phocoena phocoena) found on the coast of southern maine. maine cdc, in consultation with cdc, initiated an investigation of potential occupational exposures of staff members at university a and at diagnostic laboratories known to have handled samples from the porpoise. this report describes the results of that investigation. in humans, brucello ... | 2012 | 22739776 |
