Linear infrastructures such as railways and roads can be barriers to the movements of individuals and, hence, may have strong impacts on populations. We tested the barrier effect of a high-speed railway for Pyronia tithonus, a butterfly species showing homing behaviour when displaced. We captured, marked and displaced 152 individuals in two different locations. One-third of the butterflies were released at a capture plot, one-third on the other side of the railway (in a similar habitat) and one… CONTINUE READING
