0165), being significantly (10%) lower during Sedation/Entangled than in the Disentangled phase (Z  =  −2.7230, P = 0.0065; Fig. 8). There was no significant difference between ODBA in dive descents between Disentangled and Recovery phases (Z  =  −1.2603, P = 0.2076). During ascents, ODBA did not differ significantly between phases (χ2 = 2.8613, P = 0.2392; Fig. 8). Mean drag forces (N) of gear removed from Eg 3911 were consistently though not significantly

greater at all speeds with buoys attached (Table 4). Sinkline drag forces were intermediate between gear-only and gear-and-buoy configurations (Table 4). Mean drag forces showed no significant difference between surface and 2 m anchor points for gear-only (P = 0.4595), gear-and-buoys (P = 0.4888) or sinkline (P = 0.4965) configurations (Devore 2008). The mean theoretical drag coefficient of a nonentangled right whale (Cd,n) of Eg 3911′s dimensions, swimming at 0.75–2.9 m/s ranged from MG-132 manufacturer 3.7 × 10−3 to 2.9 × 10−3, respectively (mean ± SD; Cd,n = 3.2 × 10−3 ± 0.0003; Fig. 9). The

drag coefficient for each entangled gear scenario was calculated by applying Equation (6) (Cd = DT/(1/2)ρU2Awγkg). Though drag coefficients for Eg 3911 entangled in all gear configurations differed based on the value of k (Fig. 10), the most conservative estimates with k = 3 (Cd,e,go = 3.4 × 10−3 ± 0.0003, Cd,e,gb = 3.7 × 10−3 ± 0.0003, Cd,e,sl = 3.8 × 10−3 ± 0.0004) were significantly greater than in the nonentangled case (Wilcoxon signed rank, P = 0.0156, 0.0312, 0.0078, respectively). Having http://www.selleckchem.com/products/midostaurin-pkc412.html made low (Kleiber) and high (3 ×  Kleiber) estimates selleck compound of BMR, and using two values of k (1 and 3), we present drag and power requirements as the lower (k = 1, BMR = Kleiber) and upper (k = 3, BMR = 3 ×  Kleiber) bounds of the model results. Drag forces on Eg 3911 while not entangled ranged from 37.2 N to 1,263 N at 0.75–2.9 m/s. The associated total power requirements in the nonentangled condition (Eq. 11) ranged from 2,791 W to 16,140 W (Fig 10). Locomotory power requirements ranged from 191 W to 25,021 W. Drag forces on Eg 3911 entangled in various gear configurations are summarized

in Table 5. Across all gear configurations, mean entangled drag values ranged from 62.1 N to 2,421 N. Increases in total power input over the normal (nonentangled) condition ranged from 4.1% to 58.8% for the gear-only configuration, 4.9% to 82.5% for the sinkline configuration, and 4.8% to 120.9% for the gear-and-buoy configuration (Fig. 9). Locomotory power requirements increased on average 70.5% (SD 9.5) for the gear-only configuration, 91.0% (22.5) for the sinkline configuration, and 101.9% (31.9) for the gear-and-buoy configuration (total range 60.0%–164.6%). Alternatively, to maintain the same power output over the range of swimming speeds, an individual entangled in gear-only, sinkline, and gear-and-buoy configurations would need to decrease swimming speed by 16.2% (SD 1.5), 19.2% (3.0), or 20.5% (3.9), respectively (total range 14.5%–27.7%).
