Principal Component Analysis further distinguished between the provenances, leveraging variability in Mg, Mn, Sr, and Y elements. Notably, luminescence intensity ratios also varied among regions, aiding in provenance discrimination. The study's findings imply that Afghan lapis lazuli was the most probable source for the archaeological materials examined.

Eleven plant species from Kahuzi-Biega National Park, Democratic Republic of Congo, exhibit seed oil yields comparable to or exceeding those of major food crops like soybean and olive. Notably, Podocarpus usambarensis demonstrates a high unsaponifiable matter content, suggesting potential cosmetic applications, while five oils display melting points typical of edible oils. The study extracted oils using ethyl ether in a Soxhlet apparatus and analyzed physicochemical properties such as specific gravity (ranging from 0.8050 to 0.9854), melting point (-12 to 32°C), saponification values (182.5–260.9 mg KOH/g), acidity index (1.74–5.31 mg KOH/g), and unsaponifiable matter (0.54–2.25%). These findings highlight the park's biodiversity as a valuable resource for both nutritional and medicinal uses, reinforcing its ecological significance.

A groundbreaking study reveals that the Elephanta Caves, renowned for their religious artistry and architecture, also exhibit geological features akin to those formed by endogenous expansion in basaltic lava flows, such as pahoehoe flows in Hawaii and Iceland. Despite differences in flow volumes and environmental conditions, the caves' morphologies and internal structures mirror those of volcanic formations, suggesting a shared geological process. This finding highlights the dual significance of Elephanta Caves as both a cultural and geological landmark. The research employs field observations and computational analysis to uncover these parallels, offering new insights into the interplay between human craftsmanship and natural processes.

Extreme rainfall exacerbates fissure propagation and structural instability in grotto roofs, as demonstrated by a study on the Dazu Rock Carvings. The research reveals that rainfall-induced water pressure and humidity increase tensile stress on roof plates, accelerating deformation caused by surrounding rock settlement and tensile-shear failure. A cavity on the southern side further destabilizes the structure, with rainfall intensifying sidewall instability near this feature. To address these challenges, a reinforcement strategy leverages the bearing capacity of overlying rock layers to support the roof while minimizing interference with internal sculptures. The study combines Rayleigh wave imaging, theoretical analysis, numerical simulation, and multi-dimensional on-site monitoring to clarify damage evolution and guide targeted conservation measures.

National parks on the Qinghai–Tibet Plateau exhibit a distinct spatial distribution pattern characterized by higher density and agglomeration in the southwest, particularly along the Pamir-Himalaya region, with fewer and more dispersed parks in the northeast. This study analyzed 51 national parks across eight countries, covering 28% of the plateau's area, revealing two development phases: initial growth followed by continuous prosperity. Using Geographic Concentration Index and Kernel Density Index, researchers found that while park quantity decreases from southwest to northeast, construction scale increases, likely influenced by policy. The findings highlight critical ecological nodes and biodiversity hotspots, offering actionable insights for policymakers to balance conservation efforts across the region.

Subsistence hunting by sedentarised Baka communities, even when spatially managed with no-take zones, significantly alters the abundance and composition of wildlife assemblages in tropical forests. While species richness remains relatively stable, the study found marked reductions in carnivores, seed dispersers, and granivores compared to non-hunted reference areas within the Dja Faunal Reserve. This suggests that spatial hunting management may not fully mitigate ecological impacts on key functional groups, raising concerns about the sustainability of Indigenous livelihoods and forest ecosystems. The research employed extensive camera trap surveys across 10 Baka hunting zones to assess species occupancy, abundance, and community dynamics.
