The Charolais breed has successfully adapted to the Amazonian conditions of Ecuador. The implementation of reproductive and molecular biotechnologies has positioned this breed as the most genetically significant for improvement programs in the region. The objective of this study was to estimate genetic parameters for age at first calving (AFC) under Normal and survival models. Data included animals born between 2010 and 2021, with calving records spanning from 2012 to 2024. The total number of records was 700 after editing. Sire and animal models were considered for the analysis of AFC. The mean AFC was 3.44 years with a standard deviation of 1.19 years. Contemporary group had a significant effect on AFC, but type of cross and multiple ovulation and embryo transfer status had no impact. Under normality assumptions, heritability estimates ranged from 0.17 to 0.21 for sire and animal models, respectively. On the other hand, for the Weibull survival model heritability ranged from 0.45 to 0.74 for sire and animal model, respectively. Estimates for the sire and animal models under Normal assumptions were similar to those reported in literature and thus suggest appropriate model fit. This constitutes an additional step into routine genetic evaluation in Ecuadorian beef cattle. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026.

This quasi-experimental study aimed to evaluate the effectiveness of collaborative teaching strategies mediated by digital technologies among online university students. The research was conducted with a sample of 256 participants, divided into an experimental group and a control group. While both groups used technological resources, only the experimental group engaged in structured collaborative strategies using tools such as Genially, Kahoot, Canva, Padlet, and Wordwall, within the framework of the Cátedra Integradora course. The results revealed a significant improvement in the academic performance of the experimental group, with an average increase of 27.4%, compared to 13.2% in the control group. Furthermore, the teacher's perception highlighted higher levels of student engagement, motivation, and collaboration among those who actively participated in the strategies. These findings demonstrate that the intentional use of educational technologies with a collaborative focus fosters active, participatory, and meaningful learning, while also strengthening socio-emotional skills and improving academic achievement in virtual higher education settings. © 2025 IEEE.

Macrophotography is proving to be an educational tool for capturing details of the objects photographed, particularly to reveal the amazing variety of colors and shapes that characterize moths. In this sense, it is a tool that can well promote entomotourism in the community of Chonta Punta, located in the province of Napo—Ecuador for older people. Moth activity was documented during 17 nightly monitoring sessions at three randomly selected locations in the Yachana Foundation, Agua Santa. 4497 images were taken, and 395 species were identified. The usefulness of macrophotography in revealing useful information about insects was documented and supported by a systematic literature review. The literature review revealed that primary forests harbor moth species absent from eucalyptus plantations. Reporting on these insects demonstrates their potential as attractions within entomotourism, as well as their role as indicators of forest health. The country has untapped potential to turn moth diversity into a tourist attraction. Examples such as the butterfly farms in Mindo, just 2 h from Quito, are clear evidence of the interest butterflies generate among visitors. In addition, experiences such as visiting bioluminescent worms in New Zealand present insects as an attraction. In the context of this research, macrophotography is positioned as an indispensable tool for the identification of insects, allowing a detailed study of their morphology and unique characteristics, as a basis for the development of cultural and tourist proposals around these insects.

Painting since ancient times has been part of the indigenous people as a form of expression and a path of development, a creative activity that, like all the others, fluctuates between the net aesthetic impulse and the tacit demand of the market. The painting values the indigenous tradition and seeks to repair the abuses of its population, which has suffered, rejection and ignorance by society, both politically, socially, economically, and culturally over time. The pioneers in indigenist paintings were indigenous people from the Tigua area, among others. For the development of this work, a review of the bibliography is considered, through consultations conducted in the databases of scientific articles focused on the indigenous painting of Ecuador. The results have shown, among other things, the particularities of indigenist painting, they have found that in Ecuador, from the second half of the 20th century, artists such as Eduardo Kingman and Oswaldo Guayasamín appear, and later representatives such as Heriberto Chango, make that indigenous painting be seen in a different way, Roberto Gómez, who uses a pseudonym “CAPAC”, as a recognition of the vindication of culture, ancestral knowledge and of his remote ancestors, in the same way Cristóbal Ortega Maila, Ramón Piaguaje, an artist Amazonian, Naekat Tiwip Chamik, from the Shuar culture. From that vision a current of indigenous painters was born who have taken over the art of painting as a form of representation of their knowledge of nature. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Classic pastries in Ecuadorian cuisine are a rich blend of Indigenous, Spanish, and African influences. Among the most beloved desserts are colada morada, a thick, fruit- and purple-corn-based drink, and guaguas de pan, sweet bread rolls shaped like babies and traditionally enjoyed on All Souls’ Day. Other popular treats include empanadas de viento, light, fried pastries filled with cheese or sprinkled with sugar, and tres leches cake, a moist, sponge cake soaked in a blend of three different kinds of milk. Ecuadorian pastries frequently feature panela (unrefined cane sugar) and chocolate as key ingredients. The quality of food perceived by consumers is essential, profoundly influencing satisfaction and the overall culinary experience. This encompasses taste, presentation, freshness, nutritional value, safety, and the broader gastronomic ambiance
