Nature-Based Solutions Benefit the Economic–Ecological Coordination of Pastoral Areas: An Outstanding Herdsman’s Experience in Xilin Gol, China

Grassland has always had a difficult economic–ecological relationship, as coordination between its ecological conservation and the sustainable development of animal husbandry is required. Nature-based Solutions (NbS), who make full use of the natural ecosystem services, have successfully solved some economic–ecological issues, but still have unclear implementation prospects for grassland management. The Xilin Gol grassland is one of the most typical pastoral areas in China; there is a village chief named Bateer, who has already used NbS for grassland management. To confirm whether the solutions employed by Bateer have been effective for both increasing economic profits and protecting grassland ecosystem, we interviewed him, and many other herdsmen, using questionnaires about their livelihood. Based on these questionnaires, we calculated and compared their income–cost ratios. Meanwhile, we analyzed the NDVI variations inside their rangelands through high-resolution remote sensing images. The results showed that the herdsmen in Bateer’s village had a much higher disposable income and income–cost ratio than others, and their rangelands also had a higher value and a more obvious increasing trend of NDVI. Bateer’s success proves that the NbS can also play a positive role in grassland management, which can provide a valuable guidance for economic–ecological coordination in pastoral areas.

A Review of Human-Elephant Ecological Relations in the Malay Peninsula: Adaptations for Coexistence

Understanding the relationship between humans and elephants is of particular interest for reducing conflict and encouraging coexistence. This paper reviews the ecological relationship between humans and Asian elephants (Elephas maximus) in the rainforests of the Malay Peninsula, examining the extent of differentiation of spatio-temporal and trophic niches. We highlight the strategies that people and elephants use to partition an overlapping fundamental niche. When elephants are present, forest-dwelling people often build above-the-ground shelters; and when people are present, elephants avoid open areas during the day. People are able to access several foods that are out of reach of elephants or inedible; for example, people use water to leach poisons from tubers of wild yams, use blowpipes to kill arboreal game, and climb trees to access honey. We discuss how the transition to agriculture affected the human–elephant relationship by increasing the potential for competition. We conclude that the traditional foraging cultures of the Malay Peninsula are compatible with wildlife conservation.

The Characteristics, Structural Level and Construction Path of Collaborative Ecosystem of Innovation and Entrepreneurship Education in Universities

Mass entrepreneurship and innovation education in colleges and universities is a systematic project promoted as a whole, which pays attention to the cooperation between different participants and the coupling between top-level design and landing implementation, showing a horizontal and vertical intertwined ecological relationship. Constructing the collaborative ecosystem of innovation and entrepreneurship education in colleges and universities is an important topic to promote the comprehensive reform of colleges and universities, a key way to stimulate the innovation and entrepreneurship vitality of the whole society, and the only way to implement the strategy of "strengthening the country through innovation". The research shows that the collaborative ecosystem of innovation and entrepreneurship education in colleges and universities has the characteristics of the openness of the system boundary, the non-equilibrium of the system state, the nonlinearity of the system dynamics and the fluctuation of the system movement, and includes subject collaboration level, system collaboration level and environmental collaboration level. In terms of the construction path, the research further believes that the construction path of the collaborative ecosystem of innovation and entrepreneurship education in colleges and universities includes three aspects: establishing the system structure, releasing the system power and ensuring the development of the system. Among them, the establishment of the system structure is the premise and the release of the system power is fundamental.

Ecological Linkages Between Snails and Litters In Mount Gandang Dewata, West Sulawesi

Mount Gandang Dewata in West Sulawesi was recently granted National Park status. Exploration of land snails in Taman Nasional Gandang Dewata (TNGD) has never been carried out. Therefore, a study of land snails in the National Park was conducted in April 2016 to examine the composition of land snails in different habitats, namely primary and secondary forests. Overall, 43 specimens (21 species from 8 families) were found from eight study sites. Snails are not found in steep areas, on moderate slopes 1-10 snails are found, and in flat areas 8-13 snails are found. The analysis was carried out by the principal components (PCA). According to the PCA, three groups of snails were formed. Environmental factors such as litter, altitude, humidity, calcium (Ca), nitrogen (N), and sodium (Na) are discussed in relation to snails. In this paper, litter factors are discussed in greater depth than other environmental factors. Snails and litter interact in an ecological relationship in the forest ecosystem of Mount Gandang Dewata.

Competition and Exploitation for Ecological Capital Embodied in International Trade: Evidence from China and its Trade Partners

In order to identify ecological relationships of participating countries in the transfer system of ecological capital embodied in global trade, this paper takes the international trade of China and its partners from 2002 to 2017 as a case, and uses the ecological footprint (EF) measured by the optimized product land-use matrix (PLUM) method to quantify ecological capital for the value of macro-ecological resources, then uses the ecological network analysis (ENA) method to construct a complete transfer network of trade-embodied ecological capital and uses a utility analysis to identify ecological relationships between trading countries. Our results show that: (1) Throughout the study period, competition relationships with 61% dominated in the network, and the countries that have a pair-wise competition relationship with China are mainly located in central and western Europe, northeastern Europe, North America, southern Asia and eastern Asia. (2) Indirect utility determines the dominant ecological relationship in system, and it mainly converts dominant ecological relationships from control to competition by transforming exploit into competition. (3) China is looking to creating a more mutually beneficial trading environment at the expense of its own interests. (4) A global crisis event is likely to result in the control of ecological capital in more countries, and in its aftermath, the world is likely to be in a highly competitive environment. Reducing ecological capital consumption by improving energy efficiency and optimizing the global trading environment into a trading system dominated by mutualism relationships can be effective ways for countries around the world to achieve sustainable development post-COVID-19 crisis.

Distribution and Influence on the Microbial Ecological Relationship of Antibiotic Resistance Genes in Soil at a Watershed Scale

Antibiotic resistance genes (ARGs) are ubiquitous in the environment, with previous studies mainly focusing on the terrestrial ecosystem, which is prone to higher antibiotic application. However, the characteristics, distribution pattern, and driving factors of soil ARGs at the macro scale are still unclear. In this study, the soil ARGs, antibiotics, mobile genetic elements (MGEs), soil properties, toxic metals, polycyclic aromatic hydrocarbons (PAHs), and bacterial community in the Taipu River Basin were analyzed to investigate the distribution and dissemination of ARGs at a watershed scale. The results revealed that ARGs were widespread in the soils along the Taipu River, and that ARG profiles varied greatly with different types of land use, but showed regional similarities. The characteristics were mainly determined by antibiotic input and the ARG transmission mediated by MGEs. The order of the contribution of environmental factors to ARG distribution was toxic metals > PAHs > soil properties. Toxic metal pollution was coupled with ARGs through MGE mediation, while PAHs and soil properties were most likely to affect the ARG distribution by shifting the bacterial community. The microbial–ecological relationship changed significantly with the enrichment of ARGs, and its impact may extend to the watershed scale. Transposon IS1247 can be used as an indicator of the ARGs impact on the microbial ecological relationship in the soils of the Taipu River Basin.

The Change of Catalase Enzyme Activity in Soils by The Land Use

Analysing the factors driving the population size and activities of soil microorganisms is important for understanding the soil ecosystem’s structure and functioning. For this purpose, the soil enzymes are used as an indicator of soil microbial activity and soil fertility. Although there are many studies on the distribution and activities of various soil enzymes in soils under monoculture or crop alternation conditions, there are only few studies examining the ecological relationship in natural ecosystems, especially by using enzymes. In this study, it was aimed to determine the effect of different land uses on the catalase enzyme activity in soil. For this purpose, the catalase enzyme activities in soil samples taken from 0-5cm and 5-10cm depths in agricultural, forest, and pasture lands in north and south exposures were determined and the effects of different land use, exposure, and soil depth conditions on the enzyme activities were investigated. At the end of the study, it was determined that the catalase enzyme activity significantly differed by the land use and the highest level of catalase enzyme activity in both south and north exposures and at both depth levels was found in forest soils, whereas the lowest level of activity was found in agricultural lands in north exposure and pasture soils in south exposure.

Examining foreign language teaching and learning in Nepal: an ecological perspective

In recent years, in Nepal, while some languages of the nation are on the verge of extinction, some foreign languages (such as Japanese, Korean, Chinese) are emerging as new attractions among the youths and adults and are widely taught in the marketplaces through the private sector initiative. Against this backdrop, in this article, we have examined the current foreign language teaching and learning situation drawing on qualitative empirical data obtained from the institutes involved in foreign language instruction in a city in Gandaki Province of Nepal. The data were collected from a survey in forty institutes, ten individual interviews and five focus group discussions. Drawing on the data, an ecological model was adopted, which focused on dynamic interaction, co-existence, and competition among languages, and findings were discussed in line with these aspects of ecological understanding. Findings revealed that learning foreign languages has been established as a conduit towards economic gains and opportunities for employment and education, which has largely been contributory towards reshaping the ecological relationship among the foreign languages in Nepal.

Symbiosis in the Cambrian: enteropneust tubes from the Burgess Shale co-inhabited by commensal polychaetes

The in situ preservation of animal behaviour in the fossil record is exceedingly rare, but can lead to unique macroecological and macroevolutionary insights, especially regarding early representatives of major animal clades. We describe a new complex ecological relationship from the middle Cambrian Burgess Shale (Raymond Quarry, Canada). More than 30 organic tubes were recorded with multiple enteropneust and polychaete worms preserved within them. Based on the tubicolous nature of fossil enteropneusts, we suggest that they were the tube builders while the co-preserved polychaetes were commensals. These findings mark, to our knowledge, the first record of commensalism within Annelida and Hemichordata in the entire fossil record. The finding of multiple enteropneusts sharing common tubes suggests that either the tubes represent reproductive structures built by larger adults, and the enteropneusts commonly preserved within are juveniles, or these enteropneusts were living as a pseudo-colony without obligate attachment to each other, and the tube was built collaboratively. While neither hypothesis can be ruled out, gregarious behaviour was clearly an early trait of both hemichordates and annelids. Further, commensal symbioses in the Cambrian may be more common than currently recognized.
