lacunr: Efficient 3D lacunarity for voxelized LiDAR data from forested ecosystems

Methods in Ecology and Evolution, EarlyView.
Abstract Structural complexity has been considered a key driver of ecological phenomena in forested ecosystems. Geographic metrics that attempt to summarize the heterogeneity of complex 3‐dimensional (3D) spatial structures, such as fractal dimension and rugosity, provide insights into ecological processes such as biodiversity, productivity and ...

Effects of Anthropogenic Introduction of Substrates on Egg Camouflage and Nesting Success in Ground‐Nesting Birds

Animal Conservation, EarlyView.
We show that the introduction of artificial substrates, in this case, dredged materials to act as nesting substrate for ground‐nesting birds, reduced the effectiveness of egg camouflage for Kentish plovers compared to natural substrates. However, nesting success was not impacted, likely because the community of nest predators was diverse and used a ...

Enhancing stone provenance studies through software built with language model artificial intelligence (AI): An example of ancient Calabrian quarries (southern Italy)

Archaeometry, EarlyView.
Abstract This study represents the first attempt to develop archaeometric software that enables researchers without programming knowledge to address archaeometric challenges, specifically determining the provenance of rocks extracted from ancient quarries.

What can lithics tell us about food production during the transition to farming? Exploring harvesting practices and cultural changes during the neolithic in Southwest Asia: a view from Qminas (north‐western Syria)

Archaeometry, EarlyView.
Abstract This study examines the continuity and change in harvesting practices between the Late Pre‐Pottery Neolithic B (LPPNB) and the Early Pottery Neolithic at Qminas, north‐western Levant, through a traceological analysis of flint sickles. By combining qualitative traceological analysis with quantitative functional approaches, we demonstrate that ...
