This paper explores an important issue, namely rural tourism, by analyzing the supply and demand of tourism in three rural regions (Gura Humorului, Câmpulung Moldovenesc, and Dorna) in Bucovina, Suceava County, as an alternative economic development for rural areas. The statistical data on tourist traffic in the three regions of Suceava County were taken from the website of the National Institute of Statistics of Romania and analyzed over a period of 10 years (2014–2023). The analysis of the total number of tourist accommodation facilities recorded increases of over 200% in all three regions analyzed. Dynamic analysis of the accommodation capacity in operation, the number of tourists and overnight stays, and the average length of stay was carried out by calculating the absolute and relative indicators with fixed and chained base and average indicators. Despite the increase in the number of tourists and overnight stays, the average length of stay remains relatively low. The calculation of the net utilization rate of the accommodation capacity in operation shows an efficient use of the accommodation facilities in the three regions analyzed. The importance of the research and the originality of this research are closely related to understanding the dynamics of tourism in the rural regions analyzed for the formation of future strategies for sustainable rural development in Bucovina.

Rural tourism in Bucovina, Romania thrives due to its unspoiled natural landscapes, preserved rural traditions, and rich ethnographic heritage, including folk architecture, crafts, and festivals. The region is renowned for its uniquely painted monasteries, part of the UNESCO World Heritage, blending history, tradition, and spirituality. This study analyzes Bucovina as a rural tourism destination, focusing on three key areas: Gura Humorului, Câmpulung Moldovenesc, and Dorna. It evaluates the region’s appeal through tourism market indicators over a 10-year period (2014-2023). Findings highlight the sector’s strong development potential, evidenced by a significant increase in accommodation facilities, lodging capacity, tourist arrivals and overnights. Rural tourism positively impacts sustainable development by preserving traditions, enhancing social life, and supporting local crafts. Despite the increase in arrivals and overnight stays, the average length of stay remains relatively low. However, Bucovina’s rural tourism continues to expand, offering a sustainable model that balances cultural heritage with economic growth. This study is crucial for understanding the region’s tourism dynamics and informing future strategies for sustainable rural development.

This study evaluated 20 barley (Hordeum vulgare L.) genotypes under well-watered and drought-induced conditions to investigate physiological and anatomical adaptations contributing to drought tolerance. Conducted using a randomized complete block design (RCBD) with three replications, the experiment quantified six key traits: Cell Membrane Thermostability (CMT), Total Chlorophyll Content (TCC), Stomata Size (SS), Stomata Frequency (SF), Leaf Venation (LV), and Epidermal Cell Size (ECS). Significant genotypic (p < 0.01), environmental (p < 0.05 or p < 0.01), and genotype × environment interaction effects (p < 0.05) were observed for all traits, highlighting both genetic diversity and environmental influence on drought responses. Under drought, mean CMT and TCC decreased from 59.85 to 54.70 and from 60.11 to 50.90, respectively, while ECS increased from 2591.80 to 2689.15, indicating adaptive anatomical reconfiguration. Principal Component Analysis explained 96.42% and 97.17% of the total variation under normal and drought conditions, respectively, underscoring robust multivariate trait discrimination. Genotypes G8, G13, and G17 consistently outperformed others, exhibiting superior CMT (60.62, 60.56, 60.55), TCC (56.66, 56.43, 56.63), and ECS (2780.32 each), along with optimal stomatal and venation traits, indicating enhanced physiological resilience. Conversely, G7, G11, and G19 exhibited inferior performance across all traits. These findings affirm the utility of integrative physiological and anatomical trait analysis in identifying drought-resilient barley genotypes and provide a strong empirical basis for their incorporation into breeding programs aimed at climate adaptation and yield stability.

The Siberian sturgeon (Acipenser baerii, Brandt, 1869) is a potamodromous freshwater species with major ecological and commercial importance. Natural populations across the main Siberian River basins have declined so severely that the species is now classified as Critically Endangered on the IUCN Red List. This narrative analysis synthesizes current scientific knowledge regarding the ecology, reproductive biology, conservation status, and nutritional value of products derived from A. baerii, with the aim of providing an integrated perspective on this species, which has recently been introduced into Romanian aquaculture and occupies the interface between biodiversity and human consumption needs. The species’ remarkable ecological and morphological plasticity, which underlies its wide natural distribution in the Ob, Irtysh, Yenisei, and Lena River basins, has also made it the dominant species in global sturgeon aquaculture, commercially farmed in Europe, Asia, and South America. Reproductive management in farming systems relies on hormonal induction, non-invasive maturity assessment, and controlled hatchery practices, while emerging no-kill technologies enable repeated caviar harvesting without sacrificing the female, improving both ethical standards and economic efficiency. From a nutritional standpoint, A. baerii yields two high-value products: caviar, a rich source of the long-chain polyunsaturated fatty acids EPA and DHA, whose dietary intake has been associated with cardiovascular and neurodevelopmental benefits in the broader nutrition literature, and meat, characterized by high-biological-value protein, a favorable amino acid profile, and significant omega-3 content. By-products such as skin, swim bladders, glands, and cartilage contribute to the higher-value utilization of the species within the circular bioeconomy. Still, notable gaps remain in genetics and sex determination methods, in early life behavioral ecology, and in cryopreservation protocols. Future work should also look at more sustainable feed formulations and new value-added products.

Tourism is an activity that contributes positively to economic growth. Although tourism should be supported because of its benefits for a region’s development, it can place a strain on the environment. Integrating the principles of sustainable development into tourism is essential to ensuring its long-term viability while protecting natural and cultural resources. The purpose of this study is to determine the extent of tourism pressure, its trends, and its impact on sustainable development in three major rural tourist regions of Romania, namely Humor, Câmpulung Moldovenesc, and Dorna, located in the historical province of Bucovina, Suceava County. An analysis of the trends in the three evaluation indicators (density, duration, and pressure level) at the rural region level (Humor Region, Câmpulung Moldovenesc Region, and Dorna Region) is warranted, as these regions are the main centers of attraction and development for rural tourism in Suceava County. Between 2001 and 2023, the density indicator (arrivals/km²) showed significant increases in all three rural regions analyzed—over 6000% in Humor, 2200% in Dorna, and 2000% in Câmpulung Moldovenesc, significantly amplifying the pressure on these three areas; the duration indicator (overnight stays/km²) recorded considerable increases of over 7400% in Humor, 2400% in Dorna, and 2250% in Câmpulung Moldovenesc, proving to be a much more severe pressure indicator than the density indicator; and the pressure level indicator (arrivals/resident population) increased substantially, by over 8000% in Humor, 2100% in Dorna, and 2000% in Câmpulung Moldovenesc, indicating profound sociocultural pressure on the rural communities analyzed. The importance of this research and the originality of this study are closely linked to an understanding of the evolution and intensity of tourism pressure in the three regions analyzed, with a view to informing future strategies for sustainable rural development. An analysis of the environmental pressure caused by tourism in the three regions of Bucovina for the period 2001–2023 reflects a shift from a localized and negligible impact to an increasingly significant pressure. Currently, the regions face the challenge of balancing rapid economic development with the critical need to preserve their unique heritage. Identifying increases in tourist pressure can facilitate the implementation of effective mitigation measures, which are essential for ensuring the sustainability of tourism-related activities in the most popular tourist regions of Bucovina.
