Researchers analyzed a globular pot from the Pucara de Volcán site using 3D modeling via close-range photogrammetry and techniques like Morphological Residue Model (MRM) and Virtual Reflectance Transformation Imaging Visualization (V-RTI). These methods enhanced surface micro-topography visibility, identifying key macro-traces such as sub-circular depressions and horizontal pressure lines that correspond to paddling. The study also suggests coiling was used for the pot's collar. While the findings highlight the potential of digital techniques in pottery analysis, their accuracy depends on the precision of 3D models.

Severe climate change in the fourteenth century led to catastrophic flooding and drought at Angkor, disrupting its water management system and contributing to the site's decline. This study reveals that mega-monsoons eroded central canals and deposited sand, reducing Greater Angkor's resilience to subsequent droughts—a critical factor in its transformation from a thriving urban complex to an early modern settlement form by the sixteenth century. The research traces Angkor's evolution from two low-density towns (Bhavapura and Hariharalaya) into a multicentric city, with development expanding westward, southward, and northward before stabilizing in the thirteenth century.

Camera traps (CTs) can significantly overestimate animal populations if their effects on behavior are not accounted for. In Taï National Park, Côte d’Ivoire, researchers found that four species—Maxwell’s duiker, Jentink’s duiker, pygmy hippopotamus, and Western chimpanzee—responded differently to CTs, with reactions varying by distance, time of day, and initial installation period. Maxwell’s duiker showed minimal reactivity (~0.11%), while others exhibited high reaction rates (up to 52.96% for pygmy hippopotamus), potentially tripling population estimates if ignored. The study highlights the need to consider species-specific behaviors when using CTs for density sampling, emphasizing the importance of minimizing human impact around traps.
