All pieces together now? A phylogenomic analysis and tribe‐level classification of the heterogeneous family Plantaginaceae

TAXON, Volume 75, Issue 4, August 2026.
Abstract The plant family Plantaginaceae comprises approximately 2100 species in 106 genera, representing around 1% of all eudicots. The current circumscription of the family has been established in recent decades based on insights from DNA‐based phylogenetic analyses, which have united genera previously considered unrelated.

Are Modern Droughts Unprecedented?

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract Global drought variability of past centuries remains poorly understood due to sparse instrumental records and limited paleoclimate reconstructions. Yet, quantifying long‐term forced and unforced variability is key for assessing the extremeness of modern (2000–2024) drought events.

Classification of Precipitable Water Vapor Regimes Revealed by Clustering of GNSS Radio Occultation and ERA5 Data

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Precipitable water vapor (PWV) is an essential parameter for the study of weather and climate behavior. This work presents a novel regional classification of PWV regimes based on clustering techniques applied to Global Navigation Satellite System radio occultation‐derived and ERA5 reanalysis data with and without seasonal removal.

Supervised Machine Learning Approach to Iron Meteorite Classification Using Random Forest: A Predictive Model to Classify Ungrouped Irons

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Iron meteorites provide insight into the formation processes of planetary cores from the early Solar System. Through further classifying individual irons into specific groups, which are assumed to represent a common parent body, greater information can be yielded into the formation processes of those bodies.

Intensified Oxygen Minimum Zone in Response to Both Insolation Maxima and Carbon Dioxide‐Driven Warmth in the Tropical North Atlantic

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract Oxygen (O2) is essential for almost all life on Earth, but O2 concentrations are rapidly declining in the oceans under global warming, stressing marine ecosystems and biogeochemical cycles. Numerical model simulations suggest greatly expanded North Atlantic Oxygen Minimum Zones (OMZs) under warm Pliocene conditions, but sparse data limit ...

Geolocation with a magnetic sensor

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2395-2407, August 2026.
Abstract Many migratory animals use spatial variation in the Earth's magnetic field for orientation and navigation. This raises the possibility of exploiting these same cues to geolocate and track migratory animals throughout their annual journeys. Magnetic‐based geolocation could be particularly valuable for small aerial and aquatic species, for which

Competition and payments to African chiefs on the Gold Coast during the slave trade, 1679‒1704

The Economic History Review, Volume 79, Issue 3, Page 1052-1081, August 2026.
Abstract The manuscript records of the Royal African Company show that the Company paid African chiefs for access to trade along the caravan routes on the Gold Coast in the seventeenth century. This paper documents and examines these payments. Using an event study, I establish that after the Glorious Revolution in 1688 when the Company's monopoly in ...

Telomere Length at Recruitment Predicts Lifespan and Lifetime Reproductive Success in the Barn Swallow (Hirundo rustica)

Molecular Ecology, Volume 35, Issue 15, August 2026.
ABSTRACT Identifying molecular mechanisms linked to variation in lifespan, reproductive output and sexually selected traits is key to understanding life‐history evolution in wild populations. Telomere length (TL) and attrition (ΔTL) have been proposed as biomarkers of somatic state and maintenance (survival).

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

Sedimentology, Volume 73, Issue 5, Page 1892-1910, August 2026.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In
