Aim: Zoobenthos are important components of local biodiversity, food webs, and biogeochemical circulation processes, and are important water quality indicators. Despite their recognized importance, current research on freshwater macrozoobenthic fauna in forested inland water bodies (reservoirs, lakes, streams) in China is lacking. To better understand macrozoobenthic communities and their ecosystem services in these habitats, we choose a typical subtropical forest reserve, the Chebaling National Nature Reserve for investigation. Methods: We conducted a two-year (2019-2020) systematic field survey across nine sampling sites of different substrates in the Chebaling National Nature Reserve, Guangdong Province. These sites encompassed experimental, buffer, and core zones, and elevations stretched from 345 m to 751 m. The surveyed habitats included forested rivers, mountain streams, ponds, reservoirs, paddy fields, and ditches, which contained substrates comprising rock, gravel, sand, hardened riverbed, and silt. We applied multiple methods to survey the various habitats, including dip netting in shallow water, brushes and tweezers to isolate attached species under rocks, and baits and shrimp cages to capture species in deep water. During field surveys, we measured species composition and their population levels. We then analyzed metrics of species composition, spatial distribution, environmental indicators, and ecosystem function. Results: In total, we identified 57 species of macrobenthic fauna (belonging to 4 phylum, 6 classes, 18 orders, and 38 families) in the reserve. Eighty percent of species were arthropods, and 90% of arthropods were aquatic insects and their nymphs. We recorded 22 species and 8 families of nymphs in Odonata (dragonflies and damselflies), which constituted 38% of all captured species. Nymphs of EPT (Ephemeroptera, Plecoptera, and Trichoptera) species•生物编目• © 易祖盛等: 广东车八岭国家级自然保护区大型底栖动物多样性 681 https://www.biodiversity-science.net 生物编目 constituted 22% of all species. We commonly recorded Semisulcospira libertina in various flowing water bodies, along with a considerable population of pristine water indicator species in the low-altitude experimental area. Conclusion: Macrozoobenthic fauna in Chebaling National Nature Reserve comprised species typical of subtropical forest freshwater ecosystems. Large proportions of species that favored flowing water conditions were recorded in sites with various water bodies and elevations, and were even recorded in disturbed sites (i.e., in both experimental areas and artificial water bodies). Most species were water quality indicators that reflected the major water forms and overall quality of the reserve. The high diversity of aquatic predatory insects we recorded indicates that there is a sufficient amount of small prey in the ecosystem. Furthermore, our results suggest that the diverse and abundant macrozoobenthos can serve as considerable source of prey to predators in the reserve. Overall, our results provide data to inventory zoobenthic species and perform...

Birds share lands with humans at a substantial scale and affect crops. Yet, at a global scale, systematic evaluations of human–bird coexistence in croplands are scarce. Here, we compiled and used meta-analysis approaches to synthesize multiple global datasets of ecological and social dimensions to understand this complex coexistence system. Our result shows that birds usually increase woody, but not herbaceous, crop production, implying that crop loss mitigation efforts are critical for a better coexistence. We reveal that many nonlethal technical measures are more effective in reducing crop loss, e.g., using scaring devices and changing sow practices, than other available methods. Besides, we find that stakeholders from low-income countries are more likely to perceive the crop losses caused by birds and are less positive toward birds than those from high-income ones. Based on our evidence, we identified potential regional clusters, particularly in tropical areas, for implementing win-win coexistence strategies. Overall, we provide an evidence-based knowledge flow and solutions for stakeholders to integrate the conservation and management of birds in croplands.

Not only great tourism development value, but also huge risk for developing of uninhabited island. Scientific and reasonable planning and especially the choice of major tourism projects is one of the key factors of its success or not. Based on Qinzhou, the fuzzy selection model and clearing evaluation index system was used based on AHP, which determining the weights of different projects. Eight uninhabited islands were taken as the example to calculate the suitability of different project development in each island. The evaluation results is consistent with the guidance for the development and utilization of islands with no residents list by the State Oceanic Administration released in 2011, which show the research methods of China's uninhabited of the island development planning and management has certain theoretical significance and application value.

Abstract. It is one of the important methods to promote the sustainable development of tourism to fully tap the marine culture, enrich the modern leisure tourism. Danjia live in Qinzhou for many years and form a unique cultural. From the clothing, ship, shed of Danjia, this article analyzes its cultural factors firstly. Then it analyses the historical and cultural value; appreciation of the aesthetic value such as food, clothing, living room, festival ritual customs etc; experience value such as making and tasting seafood delicacy, making Danjia jewellery, visiting the temple, taking part in dragon-boat race on the sea and their wedding. Finally, it points out some suggestions for developing marine tourism of Danjia culture, such as respecting for nature and promoting sustainable development; planning rationally and building a good ecological tourism area; optimizing management mechanism, strengthening supervision and so on.

Taken the Seventy-two Paths in Qinzhou as example, the ecological carrying capacity of the tourism planning of uninhabited islands group was studied in the Northern Gulf of Southern China. Based on ecological footprint model, uninhabited islands consumption model of tourism ecological footprint was the established, from the view of the restaurant, accommodation, traffic, entertainment, sightseeing and shopping. And then, the ecological deficit was calculated through the evaluation of the tourism carrying capacity of uninhabited islands. The results showed that, (1) according to the planning, 5319.03 ha of total ecological footprint was required to meet the needs of the expected tourists; (2) to provide ecological footprint planning area are 788.56ha, the ecological deficit is 4530.47ha, and the ecological deficit is 5.75 times to provided by the local ecological footprint. It cannot bear the demands of ecological footprint, and a large number of external inputs were needed to maintain the ecological equilibrium Seventy-two Paths. Consumption model of tourism ecological footprint of uninhabited island could provide some reference to the development of uninhabited island in Southern China. At the same time, the model could enrich the theory and application of ecological carrying capacity.
