The study employs a web/social media analysis strategy to examine tourists' feedback on Etna Park's naturalistic pathways, aiming to identify policy differences among stakeholders such as residents and Local Action Groups. Preliminary findings highlight disagreements across various viewpoints, which will inform future research aimed at fostering a positive relationship between nature-based tourism and the park's resilience. The goal is to recommend a coherent place storytelling that aligns projected and perceived images.

Fungi significantly contribute to the deterioration of cultural heritage, particularly under specific climatic conditions, through both physical and chemical mechanisms. A study on Fatehpur Sikri, a UNESCO World Heritage Site in India, identified six prevalent fungal species—Alternaria alternata, Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Cladosporium herbarum, and Rhizopus oryzae—that cause bio-deterioration on stone monuments. These fungi induce discoloration, bio-pitting, exfoliation, and other structural alterations through hyphal growth, acid secretion, enzyme release, and pigment production. The research highlights the irreversible damage these processes can inflict on historical artifacts, emphasizing the need for multidisciplinary collaboration among microbiologists, chemists, restorers, and conservators to mitigate such deterioration effectively.

Stable isotope analysis of fossil fauna tooth enamel from two Early Acheulean sites, Garba IVD (1.95 Ma) and Gombore IB (1.66 Ma), at Melka Kunture in Ethiopia's Upper Awash Valley reveals that all analyzed taxa were grazers consuming C4 plants, indicating extensive mountain grasslands during the Pleistocene. Oxygen isotope results further distinguish between semiaquatic and terrestrial habitats, aligning with faunal taxonomy and pollen data. While Garba IVD suggests a continuous open landscape, Gombore IB shows interruptions by forests and bushy vegetation, highlighting discrepancies in environmental reconstructions using different proxies. This study underscores the resilience of dietary strategies among Early Pleistocene taxa across varying elevations in eastern Africa.

Jabal Al-Qarah, a Miocene-era mesa within Saudi Arabia's UNESCO-listed Al-Ahsa Oasis, emerges as a globally significant geoheritage site despite its initial omission from cultural heritage recognition. This flat-topped hill, composed of calcareous sandstones and mudstones, showcases non-karstic cave systems formed by mechanical erosion and subsurface flows, offering critical insights into slope development in layered geological successions. The site also features dramatic mass movements, such as strata collapses triggered by the denudation of underlying weaker layers, further underscoring its scientific value. Beyond its geological significance, Jabal Al-Qarah holds potential for geotourism, adding to the oasis's cultural and scenic appeal.

Despite the highly fragmented landscape of Brazil's south-east Atlantic Forest, both jaguars and wild pigs exhibit connectivity among protected areas. While wild pigs, with their lower environmental requirements, show more connectivity opportunities, the study reveals that even threatened species like jaguars can traverse narrow corridors through protected areas of sustainable use and private reserves. This finding underscores the critical role these areas play in maintaining landscape integrity for both native and invasive species. The research employed expert opinion, Circuitscape analysis, and least-cost-path modeling to assess connectivity, highlighting a concerning dual-use of landscapes that benefits conservation efforts while also facilitating the spread of invasive species.
