Linking palaeo‐wildfire to depositional environmental and ecological dynamics of an Early–Middle Pennsylvanian fluvial‐tidal transition zone—Palynology and pyrolysis evidence

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
The Pennsylvanian landscape in the Forest City basin was characterised by low‐lying lycopod tree and fern swamp forests with persistently high groundwater tables and adjacent fluvial channel, floodplain and upland environments. The occurrence of abundant charcoal within a specific thin interval in the Cherokee Group indicates substantial wildfire ...

Different Methodologies Result in Opposite Patterns of Diversification Rates in Flowering Plants Across Latitudes

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Variation in mean net diversification rate (MNDR) of angiosperms in geographic units across latitude and between tropical and temperate latitudes. ABSTRACT There are two major groups of methods estimating diversification rates: One group depends on well resolved phylogenies and the other is phylogeny‐free.

Natural Areas and Reference Collections for Environmental Education in Some Arkansas Schools [PDF]

open access: yes, 1973
A survey of 20 school campuses throughout Arkansas showed that most lack natural areas for outdoor environmental education. For most Arkansas schools no checklists of local plants are available, and there are no reference collections at the schools ...

Development of a Target Enrichment Probe Set for Conifer (REMcon)

open access: yesBiology
Conifers are an ecologically and economically important seed plant group that can provide significant insights into the evolution of land plants. Molecular phylogenetics has developed as an important approach in evolutionary studies, although there have ...

Molecular basis and biological relevance of bacterial and plant pinoresinol/lariciresinol reductase specificities

open access: yesProtein Science, Volume 35, Issue 2, February 2026.
Abstract A bacterial pinoresinol/lariciresinol reductase (PLR) homolog named NrPinZ was obtained from a Novosphingobium rhizosphaerae sp. LY bacterial strain, with NrPinZ being part of its 5‐step biochemical system catabolizing pinoresinol into coniferyl aldehyde and vanillin.

A natural barrier: tick‐repellent potential of a spruce‐derived volatile blend against Hyalomma excavatum and Ixodes ricinus

open access: yesPest Management Science, Volume 82, Issue 2, Page 1481-1491, February 2026.
Both active and passive questing ticks, Hyalomma excavatum and Ixodes ricinus, were assessed for behavioural responses to two novel plant‐derived repellent volatile organic compound blends. Both tick species were repelled by the products, and both novo blends were significantly more repellent than currently available commercial products.
