“…The non-pathogenic Woesearchaeota may benefit from released metabolites of the killed bacteria by specializing in substrates not used by the pathogens, thereby avoiding direct competition with other Woesarchaeota species. Such co-operative interactions among DPANN would be consistent with the Black Queen hypothesis [ 57 ], favored by the physically stable Lake A ecosystem [ 58 , 59 ]. High-resolution microscopy with specific probes could be used to test whether this cooperative metabolism was based on physical proximity, which would provide competition-free ecological niches for DPANN archaea in highly competitive, resource-limited environments.…”

DPANN archaea account for half of the archaeal diversity of the biosphere, but with few cultivated representatives, their metabolic potential and environmental functions are poorly understood. The extreme geochemical and environmental conditions in meromictic ice-capped Lake A, in the Canadian High Arctic, provided an isolated, stratified model ecosystem to resolve the distribution and metabolism of uncultured aquatic DPANN archaea living across extreme redox and salinity gradients, from freshwater oxygenated conditions, to saline, anoxic, sulfidic waters. We recovered 28 metagenome-assembled genomes (MAGs) of DPANN archaea that provided genetic insights into their ecological function. Thiosulfate oxidation potential was detected in aerobic Woesearchaeota, whereas diverse metabolic functions were identified in anaerobic DPANN archaea, including degradation and fermentation of cellular compounds, and sulfide and polysulfide reduction. We also found evidence for “vampiristic” metabolism in several MAGs, with genes coding for pore-forming toxins, peptidoglycan degradation, and RNA scavenging. The vampiristic MAGs co-occurred with other DPANNs having complementary metabolic capacities, leading to the possibility that DPANN form interspecific consortia that recycle microbial carbon, nutrients and complex molecules through a DPANN archaeal shunt, adding hidden novel complexity to anaerobic microbial food webs.

“…Coordinating the relationships among tourist destinations has become the focus of sustainable regional tourism. Cooperation enhances regional tourism competitiveness [1][2][3][4][5]. Regional tourism cooperation indicates that most tourist destinations do not exist in isolation and often depend on each other.…”

“…Factors influencing cooperation have not been systematically considered from the perspectives of the competitiveness of tourism destinations and the relationships among tourism destinations. Only when tourist destinations are competitive can they cooperate to achieve integrated development and maximized benefits [1][2][3][4][5]. Although there have been previous studies on the competi-tiveness measurement of tourism destinations, there is a lack of relevant research regarding the construction and characteristics of cooperation networks based on the GM and the competitiveness values of tourism destinations.…”

Cooperation among tourist attractions has encouraged a new form of competition among tourist destinations. Regional tourism cooperation can create win–win scenarios for participating tourist destinations, such as complementary advantages and improved comprehensive competitiveness. This study constructed a competitiveness measurement model and evaluated the competitiveness of tourist attractions. The index variables were set to modify and establish the gravity models (GMs). The cooperation network was established using Ucinet 6.0 software, and the competitive value of the tourist attractions and the structure characteristics of the network were analyzed. The results indicate that the competitiveness of tourist attractions in Jiangsu Province and Zhejiang Province is strong, while that of attractions in Anhui Province and Shanghai is weak. Tourist attractions in Shanghai, Suzhou, and Hangzhou have strong gravity for cooperation. Furthermore, the density of the cooperation network is high. The core members of the network are mainly distributed in the eastern region of the YRD and play a core role in the tourism cooperation therein. The cooperation network can be divided into four subgroups at level 2 and seven subgroups at level 3. The conclusions of this study can help the government formulate more targeted regional tourism cooperation policies.

“…Under certain conditions and intervention, competition will eventually be transformed into cooperation [12]. From a biological perspective, Herring pointed out that it is an evolution from competition to cooperation in an ecosystem [13]. Yang believes that there will be a certain amount of competition before companies cooperate [14].…”

“…Therefore, we believe that tourist attractions should be in a competitive environment before cooperation, and they should have a certain level of competitiveness [20]. In essence, tourism destinations possess certain attractions and competitiveness through their own development, and in order to seek greater competitive advantages, they, along with other destinations, jointly launch a stable, harmonious, mutually beneficial, and dynamic balance of space cooperation [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23].…”

With the development of global economic integration and the gradual formation of unified tourism markets, strengthening regional tourism cooperation has become an internal requirement of regional tourism development but also a new way of sustainably developing tourism. This study selected the key factors affecting the cooperation of tourist attractions, including the competitiveness of tourist attractions and the relationships among tourist attractions, and established an evaluation index system and mathematical model of tourist attractions’ cooperation. Furthermore, the level of cooperation was evaluated. According to the value of the cooperation level, the spatial characteristics of the cooperation level were analyzed using a geographic information systems analytical method, which can better reflect the competitiveness, relationships, and overall cooperation level of tourist attractions. The results showed that the tourism competitiveness of tourist attractions was generally strong and their internal relations relatively close, and the overall tourism cooperation level was high. However, a two-dimensional four-quadrant map revealed that there were still great differences in tourism competitiveness among tourist attractions and their internal relations. Twenty-three tourist attractions exhibited weak tourism competitiveness and sparse relationships with other tourist attractions. The tourism competitiveness of tourist attractions and their internal relations and tourism cooperation level showed positive spatial autocorrelation and spatial agglomeration characteristics. The spatial differentiation of an “inverted U-shape” indicated that the cooperation level, tourism competitiveness, and mutual relations of tourist attractions were not balanced and that a stable and gradual spatial transformation had not been achieved. This study can provide valuable insights for the government to formulate policies and measures for regional tourism cooperation, carry out regional joint marketing, and help tourism enterprises design tourist routes.
