COI Barcoding Unveils Hidden Fish Diversity and Potential Cryptic Lineages in Inner Mongolia, China
Ecology and Evolution, Volume 16, Issue 10, October 2026.Using 1080 COI barcode sequences from 99 sites across Inner Mongolia, we uncovered 70 molecular OTUs (62 morphospecies), three cryptic lineages, and deep genetic splits within widespread species. Our results provide the first regional barcode reference while revealing both the power and the limitations of single‐locus barcoding for rapid diversity ...

On Approximately p-Wright Affine Functions in Ultrametric Spaces
Journal of Function Spaces and Applications, 2013 We prove some results for mappings taking values in ultrametric spaces and satisfying approximately a generalization of the equation of p-Wright affine functions. They are motivated by the notion of stability for functional equations.

Hearing the Serre Invariant of a Compact p‐Adic Analytic Manifold
Mathematische Nachrichten, Volume 299, Issue 10, Page 3126-3138, October 2026.ABSTRACT Using a previous novel way of defining kernel functions for Laplacian integral operators on a compact p$p$‐adic analytic manifold X$X$, one such operator Δ0s$\Delta _0^s$ with s∈R$s\in \mathbb {R}$ is applied to hearing the Serre invariant i(X)$i(X)$ by showing that a wavelet eigenvalue (with the wavelet having small support) is always ...

Journal of Biogeography, Volume 53, Issue 10, October 2026.ABSTRACT Aim The Neotropical region is the most biodiverse in the world, and several hypotheses have been proposed to explain this pattern. Among them, the most prominent are the hypotheses of biotic interchange between domains, climatic refugia during the Pleistocene and geomorphological changes during the Miocene, such as the reorganization of the ...

Journal of MathematicsThis paper aims to investigate new coincidence point theorems for self-maps under an extended rational contraction. Our approach uses the p-adic distance in partially ordered ultrametric spaces. Furthermore, to illustrate our major discoveries, we give a

Journal of Fish Biology, Volume 109, Issue 4, Page 2458-2474, October 2026.Abstract Maximum longevity varies widely among marine‐occurring fishes, but the form of its relationship with body size and the contribution of broad environmental gradients remain uncertain. We analysed 757 species, using maximum length as the primary size metric and completed mass only in sensitivity analyses.

Isometric embeddings of Polish ultrametric spaces [PDF]
, 2012 We characterize Polish ultrametric spaces all of whose isometric embeddings into the Polish ultrametric Urysohn space with the same set of distances are extensive, that is, they give rise to an embedding of their respective isometry groups.

Lipschitz‐free spaces over uniformly discrete metric spaces are 3‐Schur
Bulletin of the London Mathematical Society, Volume 58, Issue 10, October 2026.Abstract We prove that the Lipschitz‐free space over any uniformly discrete metric space has the 3‐Schur property.

Idempotent probability measures on ultrametric spaces [PDF]
, 2008 Following the construction due to Hartog and Vink we introduce a metric on the set of idempotent probability measures (Maslov measures) defined on an ultrametric space.

A Note on Ultrametric Spaces, Minimum Spanning Trees and the Topological Distance Algorithm
Information, 2020 We relate the definition of an ultrametric space to the topological distance algorithm—an algorithm defined in the context of peer-to-peer network applications.
