Researchers analyzing stable isotopes (18O and D) in cave ice within the Lena Pillars Nature Park revealed distinct isotopic signatures that reflect regional climatic conditions. The study identified three primary clusters of isotopic composition: continental, arctic, and mixed, suggesting complex moisture source dynamics influencing precipitation patterns. This finding provides new insights into paleoclimatic reconstructions for Eastern Siberia, where cave ice serves as a valuable archive of past environmental conditions. The research employed high-resolution isotopic analysis to distinguish between local and distant atmospheric influences, offering a novel approach to interpreting proxy data in periglacial environments.

Stable isotope analysis reveals that seabirds and marine foods constitute a significant portion of the diet of St Kilda field mice, particularly during seabird breeding seasons. Mice sampled from Carn Mor, where the majority of the island's seabirds nest, exhibited distinct isotopic signatures compared to other locations, indicating a higher reliance on seabird-derived foods. This finding suggests that mice may be scavenging or predating seabirds or consuming their discarded food items, potentially impacting seabird populations. The study used δ13C and δ15N ratios from mouse blood and dietary items to examine foraging behavior across three years (2010–2012), employing isotope niche and mixing models to assess seasonal and spatial variations.

The 1906–07 fêtes de Carthage, staged at the recently excavated Roman theatre of Carthage, revealed archaeology's dual role as both a nostalgic celebration and a historicist tool during French colonization in Tunisia. These elaborate pageants, involving hundreds of actors and sumptuous period costumes, drew on archaeological findings to depict French colonizers as preservers of ancient culture while consigning colonial violence to the realm of performance. The 1907 pageant featured two specially commissioned plays, including one that juxtaposed a modern poet with a Carthaginian priestess at her excavated tomb site. This study demonstrates how archaeology, as an emerging science, helped police the boundary between past and present, serving a historicist sense of time that legitimized colonial narratives through the 'reality effect'—a technique that made staged performances appear authentic.

Research reveals five distinct stakeholder perspectives on large-scale marine protected areas (LSMPAs), highlighting the multi-dimensional nature of views among those directly engaged with these conservation tools. The study, involving forty stakeholders from five sites—including established LSMPAs like the Phoenix Islands Protected Area in Kiribati and proposed ones such as Rapa Nui (Easter Island)—identified three optimistic viewpoints ('Enthusiast,' 'Purist,' and 'Relativist') and two cautious ones ('Critic' and 'Skeptic'). These findings underscore the importance of nuanced consultation processes in LSMPA governance, offering insights that could improve stakeholder dialogue and decision-making. The study employed Q Methodology to capture diverse voices, contributing valuable perspectives to global debates on LSMPAs.
