Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT Monitoring pregnancy rates can provide vital information regarding a population's viability and trajectory. This study combined drone‐based photogrammetry with biopsy darting to determine if the Scaled Mass Index (SMI) estimated from aerial images can be used to identify pregnant, free‐ranging St.

The influence of ex‐tropical cyclones on marine terrace retreat
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.Ex‐tropical cyclones can damage the integrity of marine terrace structures and contribute to erosion, but they are sometimes too infrequent to explain the longer term erosion rates of coastlines. Abstract High magnitude events, like Ex‐Tropical Cyclones, are likely to change in their trajectory, magnitude, and frequency under future climate change ...

Laser bathymetry on rough riverbed channels: State‐of‐the‐art and future prospects
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.This literature review found that topo‐bathymetric LiDAR has been successfully used to capture the structures of rough riverbeds and detect large boulders. While all of the studies that were reviewed used sensors that were operated from fixed‐wing aircraft, few studies have yet tested UAV‐borne sensors on rough riverbeds, despite the potential offered ...

Observations of coastal cliff landslide runout in southern California from 21 years of data
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.Runout distance from coastal cliff landslides along the coast of northern San Diego County, California USA between 2001 and 2023 were mapped and quantified. Results indicated cliff height influenced runout distance, and that 98% of maximum runout distances were less than half the cliff height.

Hydrodynamic and ecological effects of engineered logjams: Insights from field observations
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.Drone imaging, LSPIV and electrofishing data quantified restoration effects of engineered logjam at the Emme River (Switzerland). Placement and discharge shaped flow: Side jams created longer wakes, centre jams stronger mixing; and lower discharge intensified gap velocities, whereas wake length remained stable.

Climatic, lithologic and topographic control on alpine rock fracturing and talus evolution
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.Investigating Holocene rockwall–talus systems in an Alpine valley revealed that lithologic and topographic conditions in concert with climatic‐driven stresses and time since deglaciation result in rockwall fracture patterns that control rockfall size, erosion rates and the characteristics and evolution of talus.
