Some new evidence using fractional integration about trends, breaks and persistence in polar amplification

open access: yesScientific Reports
This paper uses fractional integration methods to obtain new evidence on polar amplification. The adopted modelling framework is very general since it allows the differencing parameter to take any real value, including fractional ones, and provides ...

Biogeography and diversification patterns in the Irano‐Turanian biodiversity hotspots inferred from a molecular phylogeny of the subendemic Iris subgenus Scorpiris (Iridaceae)

open access: yesNordic Journal of Botany, EarlyView.
The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,
