In the two cases, hare intercourse additionally the percentage of hares’ decide to try was basically unrelated in order to the body updates index

We used standardized regression coefficients to assess the effect size of the predictor variables on the three response variables. Continuous predictor variables were standardized and scaled by dividing their mean by two standard deviations (Gelman, 2008 ). sFMR and the total number of predators were log₁₀ transformed to normalize a right-skewed distribution. Multicollinearity of continuous predictor variables was not an issue because the variance inflation factor (VIF) of all continuous predictor variables remained below 1.5 for all models. We tested the linearity between the predictors and the response variables using a generalized additive mixed model (package gamm4 version 0.2-6). The predictors had an effective degree of freedom (edf) close to 1 and were therefore linearly related to the response variables. Model selection was performed by using the “drop1” protocol of Zuur et al. ( 2009 ) and the Akaike information criteria (AIC). The fit of the models was assessed using plots of model residuals.

For the metabolic rate models on body condition, the final model gratis app incontri trans included sFMR, age class, and days since the start of the data collection, whereas for predator number models, the final model only included number of predators and age class (Table 1). The sum of the field metabolic rate of predators (sFMR) was negatively related to the body condition index of hares (Marginal R 2 = .61) (Table 1). Adult hares had a 21.8% higher body condition index than subadult (p < .001), whereas the body condition index of hares increased during the research period from autumn–winter) (p = .017). For the number of predators' models, while age class was correlated to body condition, the number of predators was not (Table 1).

For metabolic activities and you will predator number models into the lbs of adrenal gland, the last model provided the brand new predator index and hare gender (Dining table dos)

• a designs are based on measurements of 66 hares into the 13 search renting amassed during a period of 34 weeks.
• b Body updates directory (human body size/hindfoot size; Murray, 2002 ), sFMR = sum of the field metabolism, Many years = subadult or mature, Time = weeks just like the start of the study collection, tNP = final number of predators. The following parameters were decrease out of finally model step 1: percentage of hares decide to try and gender out-of hares; final design dos: part of hares try, intercourse away from hares, and months since start of the research range.
• c Variables are standard by 2 SD (Gelman, 2008 ).
• d * = p < .05, *** = p < .001.
• e Subadult is resource classification.

The total field metabolism from predators (sFMR) was undoubtedly about the weight of one’s adrenals (Limited R dos = .14) (Table 2). The full level of predators, although not, is actually not related toward weight of hare adrenals (Desk dos). On the other hand, adrenals of women was indeed 0.04 ± 0.017 grams ( ± SE) big than that people from the model having sFMR, but not about design on the total number from predators. In both cases, the newest portion of hares sample, years classification, and you may days given that analysis was indeed obtained is not related on weight of adrenal glands.

For both metabolic models and predator number habits with the weight of the adrenal gland, the very last model included the fresh predator list and you may hare gender (Desk dos)

• a designs are based on size of hares inside thirteen hunting renting compiled over a period of 34 days.
• b sFMR = sum of profession metabolic rate, Intercourse = person, tNP = total number away from predators. The following details were fell off latest Patterns step one and 2: portion of hares’ decide to try, decades group, and you will weeks given that start of the studies collection.
