A Spatial Analysis of Serotine Bat (Eptesicus serotinus) Roost Location and Landscape Structure: A Case Study in Sussex, UK

Table 3

Comparison of habitat composition between roosts (𝑛=97) and controls (𝑛=100) using ring buffer analysis. Adjusted using Bonferroni correction for fifteen comparisons at each distance.
