Monitoring Population Size of Red Deer Cervus Elaphus: An Evaluation of Two Types of Census Data from Norway (2007, background): “Similarly, calf per hind ratios were not successful as a metric for recruitment in France (Bonenfant et al. 2005), which may also be related to the very low number of replications.”
Seasonal variation in diet composition and similarity of sympatric red deer Cervus elaphus and roe deer Capreolus capreolus (2008, background): “The climate is continental with oceanic influence, leading to mild winters and cool summers (mean January and July temperatures are 0.6 and 18.4xC, respectively; Bonenfant et al. 2005).”
Impact of Spatial and Temporal Variation in Calf Survival on the Growth of Elk Populations (2007, background): “We excluded sources that derived calf survival from annual calf:female ratios because this metric is a composite of fecundity and calf survival and may be confounded by changes in female age structure (Bonenfant et al. 2005).”
Effect of Enhanced Nutrition on Mule Deer Population Rate of Change (2009, background): “Others have demonstrated that young:adult female ratios can be poor measures of recruitment in ungulates and that pregnancy rates, fetal numbers, and juvenile survival rates should be estimated directly from marked animals (Bonenfant et al. 2005).”
Empirical Evidence of Density- Dependence in Populations of Large Herbivores (2009, background): “Results from several African species (kudu, impala, giraffe, and zebra) rely on count‐ratios (but see Bonenfant et al., 2005), which also assume a constant age‐structure.”
Life-History Characteristics of Mule Deer: Effects of Nutrition in a Variable Environment (2014, methodology): “24 Wildlife Monographs adult (>1 yr old) females ranged from 20.8 kg to 70.2 kg. Females that resided on the west side of the crest during summer (54.2 kg, SE¼ 0.40) were heavier than east-side females (50.0 kg, SE¼ 0.52; Table 10).”
