Techniques for cetacean-habitat modeling
Jessica V. Redfern,Megan C. Ferguson,Elizabeth A. Becker,K. D. Hyrenbach,Caroline P. Good,Jay Barlow,Kristin Kaschner,Mark F. Baumgartner,Karin A. Forney,Lisa T. Ballance,Per Fauchald,Patrick N. Halpin,T. Hamazaki,Andrew J. Pershing,Song S. Qian,Andrew J. Read,Stephen B. Reilly,Leigh G. Torres,Francisco E. Werner +18 more
TL;DR: A review of the development of cetacean-habitat models, organized according to the primary steps involved in the modeling process, can be found in this paper, where the authors discuss the purposes for which CetACH models are developed, scale issues in marine ecosystems, CETCA and habitat data collection, descriptive and statistical modeling techniques, model selection, and model evaluation.
Surface‐water constraints on herbivore foraging in the kruger national park, south africa
TL;DR: Logistic regression is used to analyze 13 years of aerial census data collected in the Kruger National Park, South Africa, and suggests that the trade-off between nutritional requirements and surface-water constraints that species face varies according to the species' water dependence, size, and gut morphology.
Assessing the Risk of Ships Striking Large Whales in Marine Spatial Planning
Jessica V. Redfern,Megan F. McKenna,Thomas J. Moore,John Calambokidis,Monica L. DeAngelis,Elizabeth A. Becker,Jay Barlow,Karin A. Forney,Paul C. Fiedler,Susan J. Chivers +9 more
TL;DR: This work assessed the risk of ships striking humpback, blue, and fin whales in alternative shipping routes derived from patterns of shipping traffic off Southern California, and developed whale-habitat models that assumed ship-strike risk was proportional to the number of whales predicted to occur within each route.

Habitat-based spatial models of cetacean density in the eastern Pacific Ocean
Karin A. Forney,Megan C. Ferguson,Elizabeth A. Becker,Paul C. Fiedler,Jessica V. Redfern,Jay Barlow,L. Ignacio Vilchis,Lisa T. Ballance +7 more
TL;DR: In this paper, the authors present species−habitat models that estimate finer scale cetacean densities within the eastern Pacific Ocean, based on 15 large-scale shipboard surveys conducted in the temperate and tropical eastern Pacific.
Surface water availability and the management of herbivore distributions in an African savanna ecosystem
TL;DR: In this article, the authors used a case study in the Kruger National Park, South Africa, to assess the contribution of perennial and ephemeral water sources to surface water availability in the dry season.
