Population and herbarium genomics provide a comprehensive framework for a revision of Microcoleus (Cyanobacteria)

open access: yesJournal of Phycology, Volume 62, Issue 2, Page 454-476, April 2026.
Abstract Microcoleus is a cosmopolitan, filamentous cyanobacterium and a key component of biological soil crusts—complex microbial communities essential for primary production in diverse terrestrial environments. Here, we performed a taxonomic revision of several species of Microcoleus based on a large population genomic dataset.

New partial skeleton of Homo habilis from the upper Burgi Member, Koobi Fora Formation, Ileret, Kenya

open access: yesThe Anatomical Record, Volume 309, Issue 3, Page 485-545, March 2026.
Abstract KNM‐ER 64061 is a partial skeleton from the upper Burgi Member of the Koobi Fora Formation (2.02–2.06 Ma) associated taphonomically and geochemically with a nearly complete mandibular dentition (KNM‐ER 64060) attributed to Homo habilis.

Is Diagnosability an Indicator of Speciation? Response to "Why One Century of Phenetics Is Enough"

open access: yes, 2014
Recently (Heller et al. 2013; H&A), we commented on a revision of the bovid taxonomy, which proposes a doubling in the number of recognized species (Groves and Grubb 2011; G&G). The subsequent response by Cotterill et al. (2014; C&A) contains a number of

Geographical Variation in Skull Morphology of a Wild Rodent (Orientallactaga sibirica) Across Environmental Gradients

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
The greatest morphological differences are observed between the northeastern regions of China and the Qinghai‐Tibet regions. Elevation and temperature are the primary climatic factors causing morphological variation. Compared to the current period, the future suitable habitat area for Five‐toed jerboa is expected to decrease and shift toward higher ...

Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

open access: yesNordic Journal of Botany, Volume 2026, Issue 3, March 2026.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Open data phylometabolomics reveals turnover‐dominated chemical divergence and clade‐specific physicochemical regimes across angiosperms

open access: yesThe Plant Journal, Volume 125, Issue 6, March 2026.
Significance Statement Using an open, reproducible phylometabolomics pipeline (LOTUS + standardized taxonomy; ~77 000 occurrences), we show that angiosperm chemodiversity diverges primarily by turnover (replacement), not nested accumulation. Despite this dynamism, major clades occupy distinct physicochemical regimes, revealing conserved constraints ...

Population Structure and Genetic Diversity Analyses Reveal Isolation That May Imperil the Northernmost Colony of the Endangered Australian Sea Lion

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Rapid warming of marine environments is threatening ecosystems, especially species at the edge of their range. This study analysed the genetic structure and diversity of Australian sea lion populations and found the northernmost population to be highly isolated with extremely low genetic variation.

Seed fossil record of Solanaceae revisited

open access: yesTAXON, Volume 75, Issue 1, February 2026.
Abstract The fossil record for Solanaceae has a complex taxonomic history, with many species originally described in the family being subsequently shown to belong in other plant families. In this work, we present an in‐depth analysis of the nightshade seed fossil record, which corresponds to the largest amount of fossil material for the family.

Age of innovation: Progress in systematic botany in the 20th century

open access: yesTAXON, Volume 75, Issue 1, February 2026.
Abstract Systematic botany can be regarded as the oldest of the botanical sciences, having originated with the ancient Greeks. Although much progress has been achieved in systematic botany over nearly two millennia, in the 20th century, many significant innovations took place in revealing processes of evolution, principles and methods of classification,
