Proportion of green areas occupied by the red fox as confirmed by snow tracking, attributed to four habitat types in Warsaw, in subsequent study periods: (a) 1976–1978 (Goszczyński J., unpbl. data), (b) 2004–2012 and (c) 2016–2019. A full circle indicates actual proportion and an empty circle indicates expected proportion of colonized areas attributed to a certain habitat type, bars depict lower and upper bound of the confidence interval.
