Boreas, EarlyView.Glacier evolution and environmental changes in the northern Jan‐Mayen from the early deglaciation and well into the Holocene are discussed. Results are based on a large chronological dataset (TCN and radiocarbon dates), integrated with field data on glacial landforms and sediments, including the use of GPR.

Automated delineation and morphometry of unclassified subglacial bedforms
Boreas, EarlyView.We present an automated tool for mapping and analysing subglacial bedforms using volumetric obscurance, without classification. Tested on ArcticDEM data, the method produces bedform outlines with 75% correspondence compared to manually digitized maps.

Boreas, EarlyView.This study presents a detailed investigation of the Velika Vrbica loess‐palaeosol sequence, situated in the Wallachian Basin of northeastern Serbia, with the aim to reconstruct palaeoenvironmental changes spanning Marine Isotope Stages (MIS) 3 to 1. Using optically stimulated luminescence (OSL) dating, low field magnetic susceptibility (χlf), and mass ...

Physically Based Real‐Time Rendering of Eclipses
Computer Graphics Forum, EarlyView.Abstract We present a novel approach for simulating eclipses, incorporating effects of light scattering and refraction in the occluder's atmosphere. Our approach not only simulates the eclipse shadow, but also allows for watching the Sun being eclipsed by the occluder.

Terrain descriptors for landscape synthesis, analysis and simulation
Computer Graphics Forum, EarlyView.Abstract Synthetic landscape generation is an active research area within Computer Graphics. Algorithms for terrain synthesis and ecosystem simulations often rely on simple descriptors such as slope, light accessibility, and drainage area. Typically, the results are assessed from a perceptual standpoint, focusing primarily on visual plausibility. Other

Ten relevant questions for applying biodiversity offsetting in the Pantanal wetland
Conservation Science and Practice, EarlyView.Here, we formulated 10 questions that discuss and illustrate how offsetting can be applied to maintain wetland integrity, economic fairness, and biodiversity conservation in the Pantanal and Upper Paraguay River basin (UPRB) We provided examples of offsetting implementation opportunities, analyze spatial compliance deficits, and illustrate requirements

Successful first rehabilitation and release of an endangered Ethiopian wolf
Conservation Science and Practice, EarlyView.Wildlife rehabilitation is widely practiced to help injured animals recover and return to the wild, particularly benefiting endangered species that have small local populations. Here, we report the first case of a rehabilitated Ethiopian wolf that was successfully released back in the Simien Mountains.

Warm or bright – Temperature and light microhabitat use in insect pollinators
Ecological Entomology, EarlyView.We investigated how bumblebee species foraging on a unique flower resource in a heterogeneous habitat might coexist thanks to differential use of light and temperature microhabitats. Our study suggests that temperature acts as a first filter of the local species pool and that, for a given temperature, the present species partition along a light ...

Ibis, EarlyView.Moulting and overwintering Common Scoter Melanitta nigra aggregate in largely undisturbed, shallow‐water marine areas, preying upon sessile benthic organisms (mainly bivalves), which do not reproduce during this period of exploitation. Assuming even prey distribution, we predict that Common Scoters would aggregate to moult in shallowest waters with ...
