Narrowly defined taxa on a global scale: The phylogeny and taxonomy of the genera Catriona and Tenellia (Nudibranchia, Trinchesiidae) favours fine-scale taxonomic differentiation and dissolution of the "lumpers & splitters" dilemma. [PDF]

Evol Appl, 2023
Abstract By applying morphological and molecular data on two genera of the nudibranch molluscs it is shown that the tension between taxonomic practice and evolutionary processes persists. A review of the related genera Catriona and Tenellia is used to demonstrate that the fine‐scale taxonomic differentiation is an important tool in the integration of ...

On quasi-consistent integration by Nordsieck methods

Journal of Computational and Applied Mathematics, 2008
Quasi-consistent numerical integration of ordinary differential equations (ODEs) \(x'(t)=g(t,x(t))\) is available since 1976, but few use in practical applications has been done, mainly because of difficulties in the implementation such as the problem of quasi-consistent integration in a non-equidistant grid.

Multivalue Collocation Methods for Ordinary and Fractional Differential Equations

Mathematics, 2022
The present paper illustrates some classes of multivalue methods for the numerical solution of ordinary and fractional differential equations. In particular, it focuses on two-step and mixed collocation methods, Nordsieck GLM collocation methods for ...

Impacts of Uncontrolled Operator Splitting Methods on Parameter Identification, Prediction Uncertainty, and Subsurface Flux Representation in Conceptual Hydrological Models

Water Resources Research, Volume 59, Issue 7, July 2023., 2023
Abstract The proper numerical representation of physical processes in mechanistic hydrological models is essential to produce robust predictions. A common problem with numerical schemes in hydrological models is that multiple concurrent fluxes are calculated sequentially.

Reassessing North Eastern Atlantic‐Mediterranean species of Trapania (Mollusca, Nudibranchia)

Zoologica Scripta, Volume 51, Issue 4, Page 447-459, July 2022., 2022
Abstract Trapania is the second largest genus belonging to the family Goniodorididae, of which most of the species are reported from Indo‐Pacific waters. To date, there are nine species of Trapania distributed along the temperate coasts of the East Atlantic Ocean and Mediterranean Sea: Trapania fusca, Trapania graeffei, Trapania hispalensis, Trapania ...

Phylogeny of the land snail Levantina reveals long‐distance dispersal in the Middle East

Zoologica Scripta, Volume 51, Issue 2, Page 161-172, March 2022., 2022
Abstract Populations of rock‐dwelling snails are often isolated from each other due to outcrops of suitable rock forming islands separated by uninhabitable habitats. By chance, some snail taxa were able to rapidly extend their distribution ranges or colonise distant areas.

The role of Anatolia in the origin of the Caucasus biodiversity hotspot illustrated by land snails in the genus Oxychilus

Cladistics, Volume 38, Issue 1, Page 83-102, February 2022., 2022
Abstract Several taxa that are distributed in the Caucasus and/or the adjacent Pontic Mountains also have representatives in the East Mediterranean region. These disjunctions could have been caused by long‐distance dispersal or be the result of extinctions in Central Anatolia caused by the aridification of the Anatolian Plateau during the Pliocene.
