Enhancing Rock Strength Prediction and Features Selection by Coupling Well Log Data and Deep Learning Approaches in Reservoir Geomechanics

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 11, Page 4724-4738, 10 August 2026.
ABSTRACT Accurate rock strength parameters play a vital role in petroleum and mining operations for sustainable drilling activities, and wellbore stability analysis. This study investigates the applicability of deep learning techniques for assessing data‐driven models, and to conduct parametric sensitivity examination for feature attributes ranking to ...

Biogeography and diversification patterns in the Irano‐Turanian biodiversity hotspots inferred from a molecular phylogeny of the subendemic Iris subgenus Scorpiris (Iridaceae)

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)

Phylogenomic analysis of Madagascar's baobabs reveals admixed populations and supports resurrection of a previously described species

TAXON, Volume 75, Issue 4, August 2026.
Abstract Baobab trees (Adansonia) are iconic members of Madagascar's biota that serve as emblems for the island's unique biodiversity. Despite this recognition, many questions remain regarding evolutionary relationships and species limits within the genus.

Museomic phylogenomics of Orthosiinae (Apocynaceae) integrating targeted sequencing and morphology

TAXON, Volume 75, Issue 4, August 2026.
Abstract Museum collections offer valuable resources for phylogenetic research, especially in taxonomically challenging groups. Here, we present a phylogenetic study of the South American Apocynaceae subtribe Orthosiinae, based on sequencing 835 nuclear genes and chloroplast genomes from ~120 species using a family‐specific probe set and multiple ...

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.
