Microclimf: Fast modelling of microclimate across real landscapes in R

Methods in Ecology and Evolution, EarlyView.
Abstract Many ecological studies require climate data, but readily available datasets are poor surrogates for the conditions that organisms experience in nature. Understanding the climatic conditions experienced by organisms requires modelling microclimate rather than relying on coarse, station‐based climate data.

Validating a low‐cost alternative to body surface area estimation: Implications for energy budgets and scaling relationships of ectotherms

Methods in Ecology and Evolution, EarlyView.
Abstract The surface area of organisms is a key parameter in ecological and evolutionary applications. For example, surface area‐dependent traits such as rates of cutaneous water loss and of heat absorbed are relevant for predicting animal desiccation rates and body temperatures.

COPIS: A robust and versatile robotic imaging system for the 3D digitization of natural history specimens with photogrammetry

Methods in Ecology and Evolution, EarlyView.
Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

Animal Conservation, EarlyView.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

Archaeometry, EarlyView.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.

Mapping Palaeolithic Imprints: Spatial Analysis of Hand Stencils in El Castillo Cave (Spain) Through Geomatic Techniques

Archaeometry, EarlyView.
ABSTRACT We present the application of a new quantitative approach to space study in Palaeolithic cave art. Using GIS, we analysed the distribution and position of hand stencils in El Castillo cave to track the gestures and behaviours of Palaeolithic societies.

Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)

Boreas, EarlyView.
Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity.

Flow‐pattern evolution of the Scandinavian Ice Sheet indicated by the subglacial lineation record over Norway, Sweden and Finland

Boreas, EarlyView.
We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

Computer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Accuracy (Trueness and Precision) of the Calibrated Intraoral Scan Protocol: An In Vitro Comparison of Three Scan Calibrator Designs In an Edentulous Implant Model

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives To introduce a universal scan calibrator (SC) and to evaluate its accuracy in the calibrated intraoral scan protocol (CISP) by comparison with two previously published SCs. Materials and Methods Three SCs were evaluated on an edentulous implant model containing six scan bodies (SBs) positioned at the screw‐retained abutment (SRA ...
