No evidence for widespread island extinctions after Pleistocene hominin arrival
(Journal article; Peer reviewed, 2021)The arrival of modern humans into previously unoccupied island ecosystems is closely linked to widespread extinction, and a key reason cited for Pleistocene megafauna extinction is anthropogenic overhunting. A common ... -

Numbers of Horned Lark Eremophila alpestris are increasing at high alpine and arctic breeding sites in Norway
(Journal article; Peer reviewed, 2022)Strong declines in number of breeding Horned Larks Eremophila alpestris were reported from several Fennoscandian breeding grounds in the 1960s and 1970s. Counts from the species’ high alpine breeding grounds at Hardangervidda, ... -
Ocean current connectivity propelling the secondary spread of a marine invasive comb jelly across western Eurasia
(Peer reviewed; Journal article, 2018-07-24)Aim: Invasive species are of increasing global concern. Nevertheless, the mechanisms driving further distribution after the initial establishment of non‐native species remain largely unresolved, especially in marine systems. ... -
