New Zealand Journal of Botany, Volume 64, Issue 3, September 2026.The Senecio matatini complex in New Zealand has a convoluted taxonomic and nomenclatural history that has not been fully resolved. This is largely due to the incomplete sampling of morphologically diverse but highly threatened limestone populations in the eastern South Island in previous genetic studies.

On Structural and Spectral Properties of Distance Magic Graphs [PDF]
A graph $G=(V,E)$ is said to be distance magic if there is a bijection $f$ from a vertex set of $G$ to the first $|V(G)|$ natural numbers such that for each vertex $v$, its weight given by $\sum_{u \in N(v)}f(u)$ is constant, where $N(v)$ is an open ...

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1476-1499, September 2026.Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Proposing a Framework to Center Justice in Ambitious Science Teaching
Science Education, Volume 110, Issue 5, Page 1302-1331, September 2026.ABSTRACT Though educators and researchers have developed shared theory and language for priorities necessary to disrupt the status quo toward more equitable science education, we lack a tool that organizes sets of teaching practices across an instructional unit to support enactment and rehearsal.

Distance Magic Cartesian Products of Graphs
A distance magic labeling of a graph G = (V,E) with |V | = n is a bijection ℓ : V → {1, . . . , n} such that the weight of every vertex v, computed as the sum of the labels on the vertices in the open neighborhood of v, is a constant.

Fine‐tuning ab initio XANES spectra calculations using the Bayesian optimization algorithm
Journal of Synchrotron Radiation, Volume 33, Issue 5, Page 1455-1466, September 2026.A Bayesian optimization technique is used to tune the FEFF and FDMNES packages and to improve matching between theoretical and experimental spectra. The tests were performed on monometallic Ni, Fe and Pd K‐edge XANES spectra using several different spectrum similarity metrics.Theoretical modeling of X‐ray absorption near‐edge structure (XANES) spectra ...

Spectral Characterization of the Hamming Graphs [PDF]
We show that the Hamming graph H(3; q) with diameter three is uniquely determined by its spectrum for q ¸ 36. Moreover, we show that for given integer D ¸ 2, any graph cospectral with the Hamming graph H(D; q) is locally the disjoint union of D copies of
