Boreas, EarlyView.Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Dynamic colour change predicts movement behaviour in a diadromous fish
Journal of Fish Biology, EarlyView.Abstract Dynamic changes in colour and pattern facilitate key behavioural functions in animals, particularly camouflage for predator avoidance. However, the benefits of colour change depend on the environmental and behavioural contexts. We tested how colour change interacts with movement behaviour in a freshwater fish by filming individuals in an open ...
