Molecular phylogeny and trait evolution of Madeiran land snails: radiation of the Geomitrini (Stylommatophora: Helicoidea: Geomitridae)

Cladistics, Volume 36, Issue 6, Page 594-616, December 2020., 2020
Abstract The Geomitrini is the most species‐rich group of land snails in the Madeiran Archipelago. The phylogeny of the group is reconstructed based on mitochondrial and nuclear genetic markers. The timing of diversification, the colonisation history of the islands of the Madeiran Archipelago and the evolution of characters of the dart apparatus are ...

How to Tailor My Process‐Based Hydrological Model? Dynamic Identifiability Analysis of Flexible Model Structures

Water Resources Research, Volume 56, Issue 8, August 2020., 2020
Abstract In the field of hydrological modeling, many alternative representations of natural processes exist. Choosing specific process formulations when building a hydrological model is therefore associated with a high degree of ambiguity and subjectivity.

An integrative approach to the taxonomy and systematics within the genus Montenegrina Boettger, 1877 (Mollusca, Gastropoda, Clausiliidae)

Journal of Zoological Systematics and Evolutionary Research, Volume 58, Issue 3, Page 691-808, August 2020., 2020
Taxonomy and systematics of Montenegrina are revised based on genital anatomical investigation combined with shell morphology and DNA sequence data. This represents a new approach to the family Clausiliidae. Montenegrina revealed astonishing variability in genital morphology.

Optimization of Nordsieck's Method for the Numerical Integration of Ordinary Differential Equations [PDF]

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1984
AbstractStability and accuracy of Nordsieck's integration method can be improved by choosing the zero‐positions of the extraneous roots of the characteristic equation in a suitable way. Optimum zero‐positions have been found by minimizing the lower bound of the interval of absolute stability and the coefficient of the truncation error.

Patterns and processes in a non‐adaptive radiation: Alopia (Gastropoda, Clausiliidae) in the Bucegi Mountains

Zoologica Scripta, Volume 49, Issue 3, Page 280-294, May 2020., 2020
Abstract We studied the door‐snail genus Alopia in the Southern Carpathians in Romania to better understand non‐adaptive radiations and the processes that determine their course. Alopia in the Bucegi Mountains offers the opportunity to study all stages of a radiation within a few kilometres.

NORDSIECK FORMS OF STIFFLY-STABLE ADAMS-TYPE CYCLIC METHODS THAT ARE INSENSITIVE TO STEP-SIZE CHANGES

, 1992
In this paper we determine a matrix S and a vector l for stiffly-stable Adams-type cyclic methods that are insensitive to step size changes by using the definition of equivalent methods, (see, e.g. [l]), in the Nordsieck notation.

Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

Journal of Quaternary Science, Volume 41, Issue 2, Page 333-360, February 2026.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.

Integrating Aegean Last Interglacial faunas into the Mediterranean palaeobiogeographic framework: New evidence from Karpathos (Greece)

Journal of Quaternary Science, Volume 41, Issue 1, Page 80-98, January 2026.
ABSTRACT The Last Interglacial (LIG) or Marine Isotope Stage (MIS) 5e, spanning 129 to 116 kyrs ago, is recognised as one of the warmest periods in the Quaternary, with global sea surface temperatures (SSTs) 1°C–2°C higher than today, sea levels 5–10 m above the current level and biogeographical range expansion of specific tropical species into the ...
