With infrared spectroscopy, we studied the bulk electronic properties of the topological antiferromagnet MnBi2Te4 with TN ≃ 25 K. With the support of band-structure calculations, we assign the intra- and interband excitations and determine the band gap of Eg ≈ 0.17 eV. We also obtain evidence for two types of conduction bands with light and very heavy carriers. The multiband free-carrier...

Ranking alien species based on their risks of causing environmental impacts : A global assessment of alien ungulates

Volery, Lara ; Jatavallabhula, Divija ; Scillitani, Laura ; Bertolino, Sandro ; Bacher, Sven

In: Global Change Biology, 2021, vol. 27, no. 5, p. 1003-1016

For an efficient allocation of the limited resources to alien species management, the most damaging species should be prioritized. Comparing alien species based on their impacts is not straightforward, as the same species can cause different types and magnitudes of impacts when introduced to different contexts, making it difficult to summarize its overall impact. The Environmental Impact...

Understanding uncertainty in the Impact Classification for Alien Taxa (ICAT) assessments

Probert, Anna F. ; Volery, Lara ; Kumschick, Sabrina ; Vimercati, Giovanni ; Bacher, Sven

In: NeoBiota, 2020, vol. 62, p. 387–405

The Environmental Impact Classification for Alien Taxa (EICAT) and the Socio- Economic Impact Classification of Alien Taxa (SEICAT) have been proposed to provide unified methods for classifying alien species according to their magnitude of impacts. EICAT and SEICAT (herein “ICAT” when refered together) were designed to facilitate the comparison between taxa and invasion contexts by using a...
