Dominance of Fructose-Associated Fructobacillus in the Gut Microbiome of Bumblebees (Bombus terrestris) Inhabiting Natural Forest Meadows

Bumblebees are key pollinators in agricultural landscapes. However, little is known about how gut microbial communities respond to anthropogenic changes. We used commercially produced colonies of buff-tailed bumblebees (Bombus terrestris) placed in three habitats. Whole guts (midgut, hindgut, and rectum) of B. terrestris specimens were dissected from the body and analyzed using 16S phylogenetic community analysis. We observed significantly different bacterial community composition between the agricultural landscapes (apple orchards and oilseed rape (Brassica napus) fields) and forest meadows, whereas differences in gut communities between the orchards and oilseed rape fields were nonsignificant. Bee-specific bacterial genera such as Lactobacillus, Snodgrassella, and Gilliamella dominated gut communities of B. terrestris specimens. In contrast, the guts of B. terrestris from forest meadows were dominated by fructose-associated Fructobacillus spp. Bacterial communities of workers were the most diverse. At the same time, those of males and young queens were less diverse, possibly reflecting greater exposure to the colony’s inner environment compared to the environment outside the colony, as well as bumblebee age. Our results suggest that habitat quality, exposure to environmental microbes, nectar quality and accessibility, and land use significantly affect gut bacterial composition in B. terrestris.

Agricultural Transformation and Its Impact on Ecosystem Services and Human Well-Being in Peri-Urban Areas: The Case of Xi’an, China

There is a gap in understanding the relationships between the transformation of agricultural landscapes, ecosystem services and human well-being in the peri-urban fringe of major cities worldwide. In this paper, we use semi-structured interviews, perception surveys, social surveys and field mapping to examine linkages between agricultural and landscape transition, ecosystem services and human well-being in five sample villages in Xi’an metropolitan zone, China. The results indicate that: (1) Agricultural change has increased landscape fragmentation, with a shift from grain to more profitable horticulture and nursery production. The farming system is more diversified and exhibits a multifunctional character. (2) This transformation has had a significant impact on the character of the agroecosystem. (3) The agricultural transformation towards greater multifunctionality has increased the supply of ecosystem services, including tourism-related activities, potentially improving human well-being. (4) Different combinations of activities in the sample villages were evaluated with respect to a well-being index, indicating the importance of combining horticulture and tourism. (5) Linkages identified between agricultural transformation, ecosystem services and human well-being may have significant implications for potential approaches within future studies.

Perception of the Values of the Biocultural Landscape Types of Slovakia by the Population

The perception of the landscape by society is becoming an integral part of many studies in terms of the quality of the living environment, sport and recreation and building and developing social relationships. To evaluate the perception and appreciation of individual landscape types by society, we used an online questionnaire as a form of sociological survey. We used the statistical method of non-metric multidimensional scaling NMDS in R package to determine the variability of responses in relation to respondents. The relationship between demographic factors and landscape perception and landscape type preferences was evaluated. The results of multidimensional scaling show a strong relationship between young men and a preference for recreation over agro-tourism. The middle generation with university education looks more frequently for cultural monuments. University-educated middle-aged men perceive the natural landscape as degraded and endangered, and middle-aged men with secondary education understand the need for the protection of traditional agricultural landscapes. It is important to integrate people’s preferences and needs into the landscape planning and decision-making processes, so that they can contribute to the creation of development plans and other strategic documents.

The Assessment of the Tourism Potential of the Tagus International Nature Reserve Landscapes Using Methods Based on the Opinion of the Demand

There are different methodologies to assess landscape preferences, however there is no consensual methodology that can be replicated to identify their tourism potential. Recent studies have focused on agricultural landscape preferences due to their cultural characteristics. Although agricultural activity conflicts with the management models of natural protected areas, traditional models and sustainable practices reveal opportunities to boost tourism in this area, both for their aesthetic value, and for the opportunity to preserve biodiversity and maintain “lively landscapes”. The present study focuses on a double approach to collect data to measure the preferences for landscape typologies to realize outdoor/recreative activities in Tagus International Nature Reserve (TINR), among them, agricultural landscapes, such as the agro-silvopastural system “Dehesa/Montado” or olive grove. The preference of the landscapes were evaluated through photographs with pairwise comparison and without photographs observation, in which 174 respondents were consulted with. The different methodologies applied allowed for the extraction of different results, which led to the assumption that in fact there is no single methodology to assess preferences. However, the application of the analytic hierarchy process (AHP) methodology with photographical pairwise comparison allowed for the extraction of more robust results when considering attractions with tourism typologies, revealing that “Cultural tourism/Rural mixed” and “Agritourism” were the most valued. This information is pertinent to support TINR managers and local tourism promoters to plan and structure products and services based on button-up methodologies.

Biodiversity Conservation Potential of Forests and Trees On Farms In the Agricultural–Forest Mosaic Landscape of Catacamas, Honduras

Biodiversity decline in the tropics requires the implementation of comprehensive landscape management where agricultural systems are necessarily an integral element of biodiversity conservation. This study evaluates the potential for biodiversity conservation within an intensive livestock-agricultural-forest mosaic landscape in Catacamas, Honduras. Tree sampling was performed in 448 plots set up within different forest and agricultural land uses: secondary forests, agroforestry coffee plantations, agriculture, pastures, live fences and riparian forest. All trees with a minimum diameter at breast height of 10 cm were identified and measured. We characterized their tree structure and diversity, and compared tree diversity between the different uses. The results indicate a high degree of tree species diversity: 375 species identified, belonging to 74 families among the 15,096 trees inventoried across 84.2 hectares, including many rare species (40% of the species registered three individuals or fewer). Biodiversity indices for agroforestry coffee were found equivalent to those for natural secondary forests in the Catacamas landscape. Combining biodiversity conservation and agricultural production is possible in human-pressured tropical landscapes through tree cover maintenance. Enrichment practices combining local producers and technical knowledge may improve tree diversity in agricultural landscapes by prioritizing a mix of forest and introduced tree species (rare and with multiple uses).
