Tracking hatchery and wild Atlantic salmon (Salmo salar) smolt during river exit and early marine migration to assess survival, predation risk and migration speed

open access: yesJournal of Fish Biology, EarlyView.
Abstract Significant declines in Atlantic salmon (Salmo salar) populations across their range have prompted an increased use of hatchery supplementation programmes to support population recovery. However, concerns persist regarding the effectiveness of these programmes due to limited understanding of how hatchery‐reared salmon perform post‐release in ...

Morpho‐structural analysis of impact craters on Pluto: Implications for the study of complex craters

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We used Pluto's global digital elevation model to automatically perform a morphometric analysis of impact craters. Triangular irregular networks (TINs) were generated for each crater, providing a detailed representation of crater topography and enabling more accurate morpho‐structural analysis. A dedicated toolkit generated radial profiles for

Comparing Multiscale Object-Based Image Analysis and Deep Learning for High-Resolution Classification of Ice Wedge Polygon Tundra

open access: yesCanadian Journal of Remote Sensing
Rising Arctic temperatures are making polygonal tundra increasingly vulnerable, primarily due to high ground ice contents. These landscapes form through soil-hydrology interactions, leading to ice wedge formation and degradation. Understanding the future

Cross‐ploidy hybridisation in Alpine woodrushes is associated with ecological additivity and scale‐dependent niche divergence

open access: yesNew Phytologist, EarlyView.
Genetic differentiation among the study species. Summary Hybridisation and whole‐genome duplication (WGD) are widespread in plants, yet their ecological consequences remain challenging to predict. In allopolyploids, where both processes coincide, ecological divergence is typically evaluated against a null hypothesis of ecological additivity.

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

open access: yesSedimentology, 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 ...

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin

open access: yesSedimentology, EarlyView.
ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.

Multi‐Omics Profiling Reveals Immunomodulatory and Pro‐Regenerative Effects of a Graphene Oxide–Collagen Scaffold in Massive Rotator Cuff Tears

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
A graphene oxide/collagen scaffold is developed for chronic massive rotator cuff tear repair. The scaffold improves compressive stability, supports reparative mesenchymal differentiation, and modulates the immune microenvironment. In chronic MRCT models, it reduces muscle degeneration, enhances tendon–bone regeneration, and improves functional recovery,

Hyperparameter Optimization for Large-Scale Remote Sensing Image Analysis Tasks: A Case Study Based on Permafrost Landform Detection Using Deep Learning

open access: yesIEEE Access
Climate change pressure on the Arctic permafrost is rising alarmingly, creating a decisive need to produce Pan-Arctic scale permafrost landform and thaw disturbance information from remote sensing (RS) data.

Mapping Arctic Coastal Ecosystems with High Resolution Optical Satellite Imagery Using a Hybrid Classification Approach

open access: yesCanadian Journal of Remote Sensing, 2017
Most mapping methods for Arctic land cover are pixel-based techniques for low resolution data, and have limitations in mapping land cover heterogeneity over complex Arctic polygonal tundra terrain.

Clinical Management of Helicobacter Infection in Captive Baboons (Papio anubis and Papio hamadryas), and Isolation and Molecular Characterization of Three Novel Helicobacter Species

open access: yesJournal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Background Helicobacter spp. are gastric or enterohepatic bacteria that can be commensal, opportunistic, or pathogenic. Few studies have evaluated Helicobacter spp. in baboons. Methods Twenty‐seven captive baboons were surveyed for Helicobacter spp. by fecal PCR, and a subset evaluated by culture.
