Donde habitan los dioses: una aproximación a los apus más altos del Tawantinsuyu
(Pontificia Universidad Católica del Perú, 2025-10-28) Vitry Di Bello, Christian
Mountains have been worshipped by various cultures throughout the world, but documented case studies of ritual climbing are scarce. In the Andes, the Inca made offerings to more than 200 mountains from the fourteenth to the sixteenth centuries, 34 of which have an elevation of more than 6000 masl. This paper reviews Inca high mountain archaeology in these extreme summits, which hold the record for the highest-altitude archaeological evidence found throughout the world. The role of the Apus as tirakuna —living landscape beings with ritual and social agency— is explored through an analysis of material remains, ethnohistorical sources and recent approaches to Andean ontology. Major mountains like Llullaillaco, Aconcagua, and Mercedario are here studied incorporating technical, logistic and symbolic dimensions. This study presents an interpretation that reconstructs the planned, systematic and animate nature of these pre-Columbian practices, thus restating the very notion of mountaineering Andean-style.

Las plumas en los rituales inkas de Tambo Viejo
(Pontificia Universidad Católica del Perú, 2025-09-17) Valdez, Lidio M.; Bettcher, Katrina J.; Serván, R. Fernando; Zárate, Florentino
The Inka state was well aware that the natural world we live in coexists with an invisible, supernatural world inhabited by divine beings who—from their standpoint—influenced human life. In order to establish and maintain good relations with these beings, the Inkas found it convenient to organise ritual ceremonies and to make various offerings. The gods corresponded to this show of goodwill by sending rains that made good harvests possible. The goods offered as presents were the best available and these included multicoloured bird feathers. This paper presents the archaeological excavations undertaken at the Inka provincial centre of Tambo Viejo, where tropical bird feathers have been found amidst several of the offerings placed inside storehouses. Here we discuss the ritual use of these items throughout the Inka period, and the special significance of their discovery amongst these goods items outside the capital city of Tawantinsuyu.

Impulsores y barreras en biotecnologías que incorporan fauna salvaje a la transición agroalimentaria
(Pontificia Universidad Católica del Perú, 2025-11-07) Imio, Juan Carlos; Lisón, Fulgencio; Fonseca Prieto, Francisca
The civilizational urgency to transition towards a sustainable agri-food system is promoting the development of agricultural methods and technologies that replace external chemical-based energy inputs. This research identifies the main drivers and perceived barriers among stakeholders regarding BATsignal, a biotechnological package that integrates bat ecosystem services into the operational framework of the agri-food system. The study employs the theoretical framework of socio-technical transitions to sustainability, using the Multi-Level Perspective (MLP) to address the complexity of this radical agricultural innovation. The research follows a qualitative case study design with a sample of 75 participants whose perceptions and experiences were gathered through semi-structured interviews and focus groups. The results revealed that the majority of stakeholders (farm owners, workers, professionals, agricultural scientists, and civil society members) support the incorporation of BATsignal into crop production. This acceptance is based on the multiple socio-cultural, economic, environmental, and health benefits perceived by the interviewees regarding the substitution of certain agrochemical inputs with bat-provided ecosystem services. However, the global media association of bats with the initial outbreak of the COVID-19 pandemic poses a challenge to the advancement of BATsignal from the socio-technical landscape. Finally, we argue that sustainable innovations that capitalize on the biological activity of wild-classified animals have opportunities within the agri-food transition, provided they detach from the practices and expectations of the dominant agro-industrial socio-technical regime.

Diversidad biológica y conservación de los parques y jardines peruanos: un análisis bibliométrico
(Pontificia Universidad Católica del Perú, 2025-10-28) Aponte, Héctor; Corrales, Mara; Aliaga-Barrera, Diego; Martin, Jean Luc
The biological diversity of parks and gardens provides different ecosystem services in the city. In order to protect it, it is important to have an idea of how much we know. The objective of this study was to bibliometrically analyze all the information on biological diversity and its conservation in Peruvian parks and gardens. For this, an information search was carried out in Scopus, Scielo, Science Direct and Google Scholar databases following the PRISMA methods; subsequently, the temporal trends of these publications were analyzed, as well as the thematic areas published, summarizing the information found. As a result, ninety scientific articles were identified, published between 2002 and 2024. The highest publication output occurred within the last nine years (p<0.05 for the Kruskal-Wallis test), with the most productive years being 2018, 2021, and 2023. Additionally, 57% of the documents were published in Peruvian journals. The most studied thematic areas were «Public spaces and conservation» and «Ornithology» and (with 32 and 18 articles respectively). Sixty-seven clusters were found among authors, of which only 4 have joint works (including only 10% of authors), suggesting an independent and sporadic advance of the research groups dedicated to the study of urban ecosystems. The need to continue studies in urban environments is discussed, particularly emphasizing those less studied thematic areas (in this case, herpetology and autoecology). Likewise, the need to establish policies for conserving biological diversity in these ecosystems is discussed; examples of good practices at the national and international levels are provided.

Análisis de la migración del río Ucayali y su influencia en los territorios de las comunidades del distrito Jenaro Herrera, Loreto, Perú
(Pontificia Universidad Católica del Perú, 2025-10-16) Caldas Carrillo, Corina Isabel; Palacios-Vega, Juan José; Escobedo Torres, Roger; Dávila Díaz, Ander; del Castillo Torres, Dennis
In the Supay-Sahua sector of the Jenaro Herrera District, the lateral migration of the Ucayali River has been eroding the banks of the Supay lagoon and during the 2022 flood it affected riparian forests and crops. Therefore, this research analyzes the fluvial dynamics and annual migration of the meander curves of the Ucayali River with satellite images from the period 1985-2021 and proposes a future scenario through temporal regression analysis and with fluvial geomorphological analysis. potential fluvial processes. The results indicate that lateral migration of the Ucayali River is increasing in the meanders surrounding the Supay and Sahua lagoons. The Supay meander curve with a migration of 36.4 m/y could erode the shore of the Supay lagoon affecting 137 ha riparian forests and crops in the Once de Agosto and Nuevo Pumacahua communities in the medium term. Likewise, the Lobillo meander curve with a progressive migration of 86.5 m/a is heading towards Laguna Sahua, and in an estimated period of 21 years it could modify the alluvial plain with potential losses of 1013 ha of riparian forests, crops and resettlement for the Once de Agosto community. The changes in the landscape would affect local transportation.
