Figure 5From: Quantitative analysis of changes in movement behaviour within and outside habitat in a specialist butterflyDistributions of turning angle. Distribution of move length for movements within habitat and in the matrix in the two landscapes, showing that movements were straighter (smaller turning angles) in the matrix. Black: observed (kernel density estimate using h = 0.5*h0, i.e. a kind of moving average: [53] p. 24 ff). Grey curve: fitted von Mises (i.e. circular normal) distribution with mean m and concentration K.Back to article page
