A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

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

Sedimentology, EarlyView.
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

Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

Sedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Temognatha sundholmi Lang sp. nov. (Coleoptera: Buprestidae), a New Species From the Great Victoria Desert and New Host Plants: An Investigation Using DNA Barcoding With Implications for Taxonomy of Temognatha and Melobasis

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT A new species of jewel beetle, Temognatha sundholmi Lang, sp. nov., is described from the Great Victoria Desert in South Australia. A broader investigation, using mtDNA COI ‘barcode’ sequences from 178 specimens representing 54 buprestid species, places the new species with Temognatha flavocincta (Gory & Laporte, 1838) in the informal ...

A spatial analysis workflow to derive landscape‐scale conservation management information from GPS‐monitored grazing livestock

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
This study presents a spatial analysis workflow for using satellite telemetry data to understand livestock movement and habitat selection in conservation grazing contexts, using GPS‐tracked cattle on the Purbeck Heaths National Nature Reserve as a case study.

Improving Biodiversity Surveillance in Arid Systems With Environmental DNA: Detection of Sceloporus Lizards in Texas

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
eDNA detection rate did not significantly differ among individuals and was not statistically associated with incubation time. However, the number of positive detections was doubled in samples extracted following CTAB extraction methods. ABSTRACT Arid lands account for over 40% of the terrestrial habitat on Earth yet rank among the least studied ...

Permanent nearshore sediment loss and inevitable retreat of cohesive bluff‐backed beaches

Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
Net volume in survey control areas at the dune‐backed beach (PB) and bluff‐backed beach (LD) is shown between surveys (‘interval’), where the first point is the difference between 2012 and 2020 JABLTCX LiDAR surveys. Cumulative totals are shown as square markers. Water levels during the same dates are shown in grey.
