This Erratum concerns the following article:
Skalski, J. R., Clawson, M. V. and Millspaugh, J. J. 2012. Model evaluation in statistical population reconstruction. — Wildlife Biology 18: 225–234.
In this paper a data set was inadvertently mislabeled as marten, rather than the correct label of fisher. Below are the passages that need to be corrected. First the published passages are given, then the corrected passages are given. The exact words which need to be changed are underlined.
On page 229 second paragraph: In an SPR model of an American marten (Martes americana) population in the upper peninsula of Michigan with 11 age classes and 12 years of data (Skalski et al. 2011), deletions of 2 and 4 of the most recent years of harvest data has little effect on historical population trends (Figure 3).
Also on page 229, the figure caption for Figure 3: Figure 3. Annual abundance trends from SPR of American martens in Michigan, USA, with varying numbers of current years of age-at-harvest data removed. The numbers of years removed is indicated by the different lines.
In an SPR model of a fisher (Martes pennanti) population in the Upper Peninsula of Michigan with 11 age classes and 12 years of data (Clawson 2010), deletions of 2 and 4 of the most recent years of harvest data has little effect on historical population trends (Figure 3).
Figure 3. Annual abundance trends from SPR of fishers in Michigan, USA, with varying numbers of current years of age-at-harvest data removed. The numbers of years removed is indicated by the diÿerent lines.
In reference to Fig. 3, both in the text and in the caption for Fig. 3, the data are erroneously labeled as being from a marten population, when in fact the data came from a fisher population. Additionally, the reference Skalski et al. (2011) was incorrect because it only referenced a publication related to marten not fishers. Instead, Clawson (2010) should be cited. Clawson (2010) is cited elsewhere in the original publication and is therefore already included in the original list of references. Skalski et al. (2011) is also cited elsewhere in the paper and therefore does not need to be removed from the original list of references.
Given the data in Skalski et al. (2012) served as an example of model evaluation, changing the label of marten to fisher does not change the interpretation or intended message of any part of the paper. Additionally, all other examples in the paper are correct.
