Morphodynamic adjustment in a watershed affected by megafires: Deadman River, British Columbia, Canada

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
The Deadman River watershed (British Columbia, Canada) was severely impacted by the Sparks Lake Fire in 2021. Timelapse photogrammetry reveals sharp post‐fire channel widening and increase in migration rate. Through multispectral remote‐sensing analysis, these morphodynamic changes are related to burn severity affecting the watershed.

Tracing river dynamics: Multi‐temporal planform evolution and morphological change analyses in a meandering reach using high‐resolution satellite imagery and UAV data

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
High‐resolution satellite imagery and UAV data enabled detailed morphometric parameter calculation, meander classification and multi‐epoch change detection for the Atrak River's meandering channel. Our results reveal rapid, episodic migration and a nearly tenfold surge in bank erosion triggered by the 2019 extreme flood, with persistent instability at ...

Decision Of EO Parameters Based On Direct Georeferencing Using SmartBase

open access: yesJournal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, 2013
Recently, it is a pretty well known way to compute GPS/INS using Continuously Operating Reference Station (CORS) and Network-based RTK for obtaining Exterior Orientation (EO) parameters of aerial photogrammetry. In this study, it is way to compute Exterior Orientation (EO) parameters using ground base stations, using Continuously Operating Reference ...

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

open access: yesOikos, Volume 2026, Issue 8, August 2026.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

New canopy legume species highlight liana gap sampling across Amazonian and Atlantic rain forests

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract Lianas are a key component of the Neotropical flora, accounting for 10% of angiosperm richness and playing important ecological roles. However, the canopy preference of some species often leads to their underrepresentation in herbarium collections, thereby exacerbating Linnaean, Darwinian, and Wallacean shortfalls. The papilionoid legume genus

Phylogenetics of Clusia sect. Criuva (Clusiaceae) unveils a new species, reinstates an old name and clarifies sectional circumscription

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract Clusia sect. Criuva has long been a taxonomic catch‐all, particularly in the final decades of the 20th century, when misapplications conflated eastern Brazilian taxa with species from the Guiana Shield. We combine herbarium‐based genome skimming, targeted fieldwork, and critical examination of historical literature and types to reassess ...

Direct Georeferencing in Aerial Photogrammetric Mapping

open access: yes, 2002
Aerial photogrammetric mapping is a well-established industry. Its methods have been evolving progressively but not explosively over many decades. Entrenched, reliable procedures have been developed to overcome pitfalls along the processing chain, allowing the delivery of high quality mapping products.

Nonlinear Kinematic Depth Inversion Coupled With a Spectral Wave Model

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract We present a bidirectional coupling between a nonlinear kinematic depth inversion method and a phase‐averaged spectral wave model to evaluate the influence of wave nonlinearity over gently sloping nearshore bathymetry. Time‐resolved wave imagery provides spatially varying frequency–wavenumber fields, whereas the simulated significant wave ...

Egg‐Carrying and Cheliceral Comb in Ibaloniinae Harvestmen From the Solomon Islands (Opiliones: Podoctidae)

open access: yesAustral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Four new species of Ibaloniinae harvestmen are described from the Solomon Islands, Melanesia. Based on the original diagnosis of Euibalonius Roewer, 1915, and description of E. maculatus (Roewer, 1915), this material appeared related to that genus. However, examination of syntype photographs of the type species E.
