Terrain Synthesis and Authoring based on Iso‐Contours

open access: yesComputer Graphics Forum, EarlyView.
Abstract Digital terrains are central to realistic landscape depiction, yet authoring tools must balance perceptual realism with intuitive artistic control. We propose a compact vector‐based representation that models terrain as nested iso‐contours, inspired by geomorphology and cartography.

Survey on differential estimators for 3d point clouds

open access: yesComputer Graphics Forum, EarlyView.
Abstract Recent advancements in 3D scanning technologies, including LiDAR and photogrammetry, have enabled the precise digital replication of real‐world objects. These methods are widely used in fields such as GIS, robotics, and cultural heritage. However, the point clouds generated by such scans are often noisy and unstructured, posing challenges for ...

A review of participatory mapping in conservation science and practice

open access: yesConservation Science and Practice, EarlyView.
There has been a recent increase and diversification in the use of participatory mapping in the field of conservation, however, methodological standards remain both disjointed and confounding. We conducted a comprehensive review of the conservation participatory mapping literature and synthesized geographical, temporal, and topical trends across a ...

Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges

open access: yesInsect Conservation and Diversity, EarlyView.
Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

Sediment addition to address tidal marsh elevation deficits caused by farm impoundments: a Delaware Bay, New Jersey, United States case study

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Dredge material use is emerging as an important technique for restoring marshes threatened by historic mismanagement and sea‐level rise, yet optimal methods to maximize ecological benefit remain under development. The Delaware Estuary is in urgent need of restoration, as historic agricultural conversion caused substantial and ...

Beyond barriers: fish assemblage recovery following dam removal on the Cuyahoga River, a Lake Erie tributary

open access: yesRestoration Ecology, EarlyView.
Dam removals are increasing globally, yet ecological outcomes vary widely because biological recovery depends on post‐removal connectivity and access to source populations. We evaluated how multiple dam removals and remaining fragmentation influenced fish assemblage recovery in the Cuyahoga River (OH, United States), a historically polluted Great Lakes

Modern microbial landscape: Aerial mapping of microbially induced sedimentary structures forming in a coastal sabkha

open access: yesSedimentology, EarlyView.
ABSTRACT Microbially induced sedimentary structures (MISS) are considered important for understanding primitive life on Earth and for guiding the search for life on other planets. These structures are regarded as macroscopic fossils of early communities of unicellular organisms that did not produce skeletons or shells. In this study, field observations
