A significant habitat loss of 67.2% is projected for the Sichuan snub-nosed monkey (Rhinopithecus roxellana) in Hubei Province, China, by the 2050s due to climate change. The study identifies critical refugia areas totaling 286 km² within Shennongjia National Park and Badong Natural Reserve, which could sustain the population despite future climate shifts. Using bioclimatic models, circuit theory, and least-cost corridors, researchers mapped potential dispersal paths for the species to move between current and future suitable habitats. This assessment underscores the importance of prioritizing conservation efforts in these refugia and connecting corridors to maintain habitat connectivity and ensure the survival of this endangered primate under changing climatic conditions.

A comparative analysis of cultural customs between the Ancient Mediterranean World (AMW) and the Shona people of Zimbabwe reveals potential similarities that challenge long-standing theories about the builders of Great Zimbabwe National Monument (GZNM). Contrary to claims linking its construction to ancient Mediterranean communities or biblical figures, this study suggests that indigenous knowledge systems (IKS) may provide a more plausible identity for the monument's architects. By examining cultural parallels, researchers aim to contribute new insights into the debate surrounding GZNM's origins, offering a perspective rooted in local traditions rather than external narratives.

Research reveals that Jørn Utzon's 1958 acquisition of the <em>Yingzao fashi</em> (Chinese Building Standards) significantly influenced the design and construction of the Sydney Opera House, serving as both a conceptual inspiration and practical guide. The study, based on primary sources from The Utzon Archives, State Library of New South Wales, and Utzon's family collection—alongside interviews with his team—demonstrates that the <em>Yingzao fashi</em>'s illustrations shaped the Opera House's aesthetic ideals and structural characteristics before Utzon’s resignation in 1966. This finding sheds new light on the cultural and technical foundations of one of the world's most iconic architectural marvels.
