Effects of habitat loss on migratory shorebird community structure at stopover sites: A case study in the Yellow River Delta, China

open access: yesFrontiers in Marine Science, 2022
Coastal wetlands in China provide important stopover sites for migratory shorebird species. The loss of natural wetlands caused by land reclamation over the past few decades poses a major threat to shorebird populations.

Functional Calculus on Non-Homogeneous Operators on Nilpotent Groups [PDF]

open access: yes, 2020
We study the functional calculus associated with a hypoelliptic left-invariant differential operator $\mathcal{L}$ on a connected and simply connected nilpotent Lie group $G$ with the aid of the corresponding \emph{Rockland} operator $\mathcal{L}_0$ on ...

Moment Functions on Groups [PDF]

open access: yesResults in Mathematics, 2021
AbstractIn this paper generalized moment functions are considered. They are closely related to the well-known functions of binomial type which have been investigated on various abstract structures. The main purpose of this work is to prove characterization theorems for generalized moment functions on commutative groups.

Summer aspect of phytoplankton communities in some Montenegrin lakes: Are there changes after more than two decades? [PDF]

open access: yesArchives of Biological Sciences, 2012
Qualitative and quantitative phytoplankton compositions of 10 Montenegrin lakes were investigated in the summer of 2007. The obtained results were compared with a previous study-period that was undertaken two decades ago.
