Based on the direct relationship between edge effect intensity and the protection of the core of the class from external factors (Riguete et al., 2013), the explanatory variables used to illustrate the intensity of edge effect were greater protection of fragment core, to explain lower edge effect intensity, and lower protection of fragment core, to explain higher edge effect intensity.
Edge Effect on the Bark-gleaning Insectivore Foraging Guild: The RDA biplot diagram indicated that the bark-gleaning insectivores were influenced by trees with diameters of 20-40 cm and >60 cm, as well as relative humidity.
We then evaluated how the strength of these relations (edge effects) varied across primary sessions.
The maximum contact pressure for a profile optimized for no edge effect is 573 MPa, which is only 7% above the ideal contact pressure distribution.

The perimeter-area relationship qualifies the edge effect: the higher the value of this metric, the greater the edge effect in the fragment.
Using the naive density estimate, our result of 27 ind./ha is likely to be severely overestimated (Dice 1938, Tanaka 1980, Wilson & Anderson 1985, Juskaitis 2006), but compared to published results that also do not account for the "edge effect", and therefore also possibly severely overestimated, our result is still 1.7 times higher than the highest densities reported: 16 adults/ha in Lithuania (Juskaitis 2006) and 15.6 adults/ha in England (Bright & Morris 1990) (for a review of common dormouse densities, see Juskaitis 2014).
Few studies have been conducted with regards to the edge effect of roads under construction.
