“…Given their small size and external attachment, the use of accelerometers should reduce the potential for injury (Green, Haulena et al, 2009) and reduce the potential for influencing the animal's behavior and related energy expenditure (but see Chivers, Hatch, & Elliott, 2016;Maresh et al, 2014;Vandenabeele et al, 2014;Walker & Boveng, 1995;Wilson, 2011). As a result, DBA is increasingly being used as a proxy for energy expenditure in free-ranging animals (Bishop et al, 2015;Bryce, Wilmers, & Williams, 2017;Enstipp et al, 2016;Grémillet et al, 2018;Halsey & White, 2010;Hicks et al, 2018;Scharf, LaPoint, Wikelski, & Safi, 2016;Udyawer, Simpfendorfer, Heupel, & Clark, 2017;Wang, Smith, & Wilmers, 2017;Williams et al, 2016Wilmers et al, 2017;Wilson et al, 2012). However, DBA may underestimate changes in energy expenditure as a result of changes in basal metabolism, thermoregulation, specific dynamic action (heat increment of feeding), reproduction, or growth Green, Halsey et al, 2009;Halsey, Shepard et al, 2011;Figure 1).…”
