(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Henbane Hyoscyamus niger is a truly exceptional plant. Few species in our flora are as enveloped with mysticism and magic as henbane. The species is monocarpic with both annual and biennial forms. Biennial plants grow a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Sets of presence records used to model species’ distributions typically consist of observations collected opportunistically rather than systematically. As a result, sampling probability is geographically uneven, which may ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Nine samples from the Alum Shale of Slemmestad, Oslo Region, were processed for conodonts. The limestone-rich interval extending from the mid Cambrian Paradoxides paradoxissimus trilobite Zone to the Lower Ordovician ...
