Course techniques design
( 2013 ), we developed a six-state movement behavior model for bearded seals, where movement behavior states and associated movement parameters were estimated from seven data streams. These data streams included step length , bearing (?letter,t), the proportion of time spent diving >4 m below the surface , the proportion of dry time , the number of dives to the sea floor (i.e., “benthic dives”; eletter,t), the average proportion of sea ice cover , and the average proportion of land cover for each 6-h time step t = 1, …, Tn and individual n = 1, …, N. Our goal was to identify and estimate activity budgets to six distinct movement behavior states, zletter,t ? , in which I denotes “hauled out on ice,” S indicates “sleep at water,” L denotes “hauled out on house,” M denotes “mid-drinking water foraging,” B denotes “benthic foraging,” and you will T indicates “transportation,” in accordance with the joint suggestions around the all the research channels. Because a good heuristic instance of how the movement process model functions, imagine a certain 6-h date step presented a short step duration, little time spent plunge below cuatro yards, 100% inactive day, and no dives for the ocean flooring; when the water ice security try >0% and you may belongings shelter are 0%, it’s possible to relatively anticipate the animal is actually hauled on ice during this period step (state We; Dining table 1).
Notes
- This type of research channels incorporated lateral trajectory (“action size” and “directional persistence”), the brand new proportion of time spent diving below 4 meters (“dive”), the latest ratio of your energy spent dead (“dry”), together with number of benthic dives (“benthic”) throughout for every six-h big date action. The brand new model integrated environment study towards the ratio regarding ocean ice and you will land safeguards within the twenty-five ?
