Oak forests are an important part of temperate European ecosystems, where they are actively improving biodiversity, carbon storage, and ecological stability. However, current concerns such as climatic changes, and especially rising temperatures and changing precipitation patterns, are impacting their resilience. In this context, our study intends to evaluate the impact of climatic variability on temperate oak forests, focusing on the influence of temperature and precipitation. This covers different sites that have different environmental conditions. By using both a bibliometric approach and a systematic analysis of publications that have studied the influence of climate change on oak forests, our study has identified specific species and site responses to climate stressors. Furthermore, we have also evaluated trends in drought sensitivity. All these aspects have allowed us to understand and suggest improvements for the impact of climate change on the resilience and productivity of oak ecosystems. We have analyzed a total number of 346 publications that target the impact of climate change on oak forests. The articles were published between 1976 and 2024, with the majority originating from the USA, Spain, Germany, and France. These studies were published in leading journals from Forestry, Environmental Sciences, and Plant Sciences, among which the most cited journals were Forest Ecology and Management, the Journal of Biogeography, and Global Change Biology. As for the keywords, the most frequent ones were climate change, drought, growth, forest, and oak. However, we have observed a trend towards drought sensitivity, which indicates the intensification of climate changes on oak ecosystems. Moreover, this trend was more present in central and southern regions, which further highlights the impact of regional conditions. As such, certain local factors (soil properties, microclimate) were also taken into account in our study. Our literature review focused on the following aspects: Oak species affected by climate change; Impact of drought on oak forests; Influence of climate change on mixed forests containing oaks; Effects of climate change on other components of oak ecosystems; Radial growth of oaks in response to climate change; Decline of oak forests due to climate change. Our results indicate that oak forests decline in a process caused by multiple factors, with climate change being both a stressor and a catalyst. Across the globe, increasing temperatures and declining precipitation affect these ecosystems in their growth, functions, and resistance to pathogens. This can only lead to an increased forest decline. As such, our results indicate the need to implement forest management plans that take into account local conditions, species, and climate sensitivity. This approach is crucial in improving the adaptivity of oak forests and mitigating the impact of future climate extremes.

The knowledge, perception, and behavior of young people toward ecotourism are important for the sustainable development of this sector. The purpose of this research is to evaluate and analyze the knowledge of young Romanian students about ecotourism and the main ecotourism destinations in Romania, their behavior in relation to the practice of this form of sustainable tourism at the local level in the last 2 years (2020 and 2021), and people’s use of the Internet for planning holidays and digital applications while traveling in nature. A quantitative research was conducted based on a self-administered questionnaire, structured in 13 sections on ecotourism, to which were added the sociodemographic data of the respondents. The conclusions of the research are that young people know well the main ecotourism destinations in Romania; they choose them according to the beauty of the landscape, multitude of outdoor activities, and the hospitality of the hosts. In the last 2 years of the pandemic, young people have visited several times the main existing ecotourism destinations locally, with an average vacation duration of 1–3 days. The Internet remains the main source of information, and in the field, they use mobile applications that allow the download of digital maps and recognize different plant species. By integrating various activities in nature, in close connection with the local culture, ecotourism can contribute to the sustainable use of local tourism resources. This study provides a detailed and realistic picture of the knowledge and the type of ecotourism experience that young people want. The implications are theoretical and managerial, highlighting the importance of assessing the preferences of young ecotourists, as a basis for developing ecotourism strategies, sustainable use of local tourism resources, and management of protected areas.

The intersection of sports and natural forests and green spaces represents an emerging interdisciplinary field with implications for public health, environmental science, and sustainable land management and refers to the variety of cultural ecosystem services demanded by people from ecosystems. This manuscript presents a systematic bibliometric and thematic analysis of 148 publications for the period 1993–2024 identified through Web of Science and Scopus, aiming to evaluate the current state of research on sports activities conducted in natural forest environments. Findings indicated a marked increase in scientific interest of this topic over the past two decades, with key contributions from countries such as England, Germany, China, and the United States. Researchers most frequently examined sports such as hiking, trail running, mountain biking, and orienteering for their capacity to provide physiological and psychological benefits, reduce stress, and enhance mental well-being. The literature analysis highlights ecological concerns, particularly those associated with habitat disturbance, biodiversity loss, and conflicts between recreation and conservation. Six principal research themes were identified: sports in urban forests, sports tourism, hunting and fishing, recreational sports, health benefits, and environmental impacts. Keyword and co-authorship analyses revealed a multidisciplinary knowledge base with evolving thematic focuses. In conclusion, the need for integrated approaches that incorporate ecological impact assessment, stakeholder perspectives, and adaptive forest governance to ensure sustainable recreational use of natural forest ecosystems is underlined.

The aim of this paper is to evaluate some villages in the mountain area of Sibiu County, Romania, as “smart” tourist villages. The research was carried out in two stages: Stage 1 was collection of information on (a) food products registered in different national and international quality schemes and (b) the number of tourist structures by type, comfort category, and accommodation capacity. Stage 2 was a case study conducted among 32 rural tourism entrepreneurs from 3 villages in Mărginimea Sibiului, using a questionnaire with 22 items on the criteria for evaluation of “smart” villages. The answers were systematized, statistically processed, and interpreted. The main results are as follows: (a) Concerning products, producers, and gastronomic points (PGL) registered, there are 9 products in the quality scheme “mountain product”, 10 producers on the platform “Gusturisibiene”, 1 producer of “telemea de Sibiu”, a registered product with protected geographical indication, and 2 PGL. (b) The number of officially registered tourist structures is 93, of which 72% are agritourism guesthouses. (c) The results for the evaluation of villages as “smart” are that 78.2% of locals use the internet, 74% own at least one smart device, 60.16% of energy used is renewable. There are low values of water and air pollution; there are local job and business opportunities (93.75%); future local development activities will target agriculture with all its sectors and agritourism; public administrations have implemented 7 types of activities to increase the attractiveness of localities; and quality of life, services, and social life aspects are perceived to be at high standards.

Dendrochronology, the study of tree-ring growth patterns, is a powerful tool for reconstructing past human–environment interactions. This review examines its role within archaeology, focusing on how tree-ring studies contribute to dating wooden artifacts, reconstructing past climates, and understanding timber use in historical buildings and cultural heritage. To explore these applications, we conducted a bibliometric analysis of studies indexed in Web of Science. Our results reveal a marked increase in dendrochronological research over the past 15 years, alongside a broadening of its impact across related fields such as anthropology and environmental sciences. We classify the literature into major thematic areas, including methodological developments, historical and environmental disruptions, art and architecture, mining history, and the ancient timber trade. By highlighting both the advantages and limitations of dendrochronology—such as issues of reference coverage, the need for non-destructive sampling, and the importance of interdisciplinary collaboration—we show how this approach extends beyond archaeology to illuminate wider cultural and environmental contexts. Ultimately, our findings demonstrate the significance of dendrochronology not only for understanding ancient civilizations and cultural heritage, but also for tracing the complex interactions between humans and natural resources across time.

Climate change is becoming more acute, including in terms of individual perception. Forest, as an ecosystem, has a special role to play in mitigating climate change, protecting the soil, water and air. There are forests of scientific interest, preservation of the Eco fund and forest Geno fund, as well as recreational forests, so that the ecological functions are fulfilled in the optimum. Also, alongside the social function, green energy generation is one of the main attributes of the forest. In addition to preserving biodiversity, the forestry administration has as objectives the provision of the necessary resources for the short, medium and long-term development of local communities. Forest management that harmoniously combines ecological, economic and social functions cannot be sustained, at least in the information age, without relying on information technology. This article aims to address the issue of information technology in the forest administration, identifying needs and providing viable, high quality, open source solutions.
