The method to determine CQ was the test for creative thinking - drawing production (TCT-DP). The results showed that 3% of the students were at A level, 15% are B level, 23% are C level, 44% are D level, 7% are E level, 6% are F level and 2% are G level. Some factors related to family characteristics that reduce the risk of low CQ and increase the posibility of high CQ were: stable occupation of parents, number of children in the family, strict mother, supportive parents when children make mistakes. Factors about children's activities that helped increase their creativity include: volunteer to be a class official, enroll in extracurricular clubs, participating in the artistic activities and enjoy artistic activities.","PeriodicalId":17007,"journal":{"name":"Journal of Science Natural Science","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82458709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Vietnam, this genus has eight species, including five that are in uncertain taxonomy status. In the present study, we described one species of Pareuchiloglanis based on collections from the Da River basin in Phong Tho district, Lai Chau province. Pareuchiloglanis sp. can be distinguished from congeners by the following unique combination of characters: D. i,6; A. i,4; P1. i,14-16 (primarily i,16); C. i,6-8,6-8,i (primarily i,8,8,i); interorbital distanceeye diameter 2.4-3.4; caudal peduncle length 17.1-21.5; caudal pedunle depth 6.0-7.0% SL; length of adipose basedorsal to adipose distance averaged 1.8; head length 19.2-24.3; anal-fin origin closer to the anus than to the caudal-fin base; adipose-fin base posterior to the tip of pelvic-fin rays; the pelvic-fin insertion located opposite to the fourth dorsal fin-ray element; maxillary barbel extending just beyond base of first pectoral-fin element; and yellow patches on dorsal surface (a broader pair on the last doral-fin ray, as large as two thirds length of pelvic-fin). Morphological analysis showed that Pareuchiloglanis sp. are closed to two species in the same surveyed area, P. tamduongensis and P. songdaensis. This paper also indicated morphological differences between Pareuchiloglanis sp. and other species that have yellow patches on dorsal surface. This species record implied the potential of biodiversity of Pareuchiloglanis in the headwaters of the Red River. These findings provide worthy data for further studies on taxonomy of this genus in northern Vietnam.","PeriodicalId":17007,"journal":{"name":"Journal of Science Natural Science","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81497566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Habitat type with standing or less flowing water such as ponds, lakes and lagoons; SC3. Habitat types such as water rice fields or aquatic plants; SC4. Habitat of standing water or puddles on the edge or inside the rice field; and SC5; and other Habitats include terrestrial, drifting with water, hiding in earthen caves near aquatic habitats.

Species’s distribution depends on many factors, the most important of which is soil structure. Derris trifoliata grows well on clay loam soil or sandy loam soil. Firm ground is less favorable for true mangrove species, so the abundance found along sea-dykes, coastal areas and aquaculture lagoons is much higher than in mangrove core zone. On sandy soil or light sandy loam soil, when sand percentage is high, plants grow poorly with very low density. Study results show that Derris trifoliata can grow on many different types of substrates, but mostly on soil with sand percentage from 39 to 50%, clay from 39 to 45% and limon about 10%. Derris trifoliata grows near sea dykes and aquaculture lagoons, the nearer it is towards sea, the lower abundance and density is. Other ecological factors such as humus content, total nitrogen, C:N ratio, and salinity also affect the distribution of Derris trifoliata but to a lesser extent. In places with high density of Derris trifoliata, although the amount of humus in the soil is not much, the average nitrogen content is high because Derris trifoliata belongs to Fabaceae family, nodules lumps formed on their roots by Rhizobium can fix nitrogen from atmospheric nitrogen.","PeriodicalId":17007,"journal":{"name":"Journal of Science Natural Science","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72814089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study systematically presents ecosystem services based on literature review of published papers, and project reports. It reveals that ecosystem services from mangrove forests are diverse and different among localities. Amongst the three types of ecosystem services, the regulating is the most concerned (accounting for 40% of reviewed literatures), followed by the provisioning (accounting for 39%) and the cultural (accounting for 21%). There are more available data on ecosystem services from mangrove forests in the North and South of Vietnam than that in the Central (24 - 26 vs. 18%). Differences in studies on ecosystem services contribute to the lack of synchronicity in biodiversity conservation and sustainable development of this typical ecosystem in Viet Nam. Also, the present paper details three types of ecosystem services, compared levels of exploitation, and use of ecosystem services from mangroves in different regions. These results are scientific fundamentals for conservation, exploitation, and sustainable utilization of this ecosystem in the eco-social development. In addition, the present study introduces several options for further studies, exploitation of ecosystem services from mangroves in Vietnam, focusing on the connectivity, the stakeholder participation and remote sensing application.","PeriodicalId":17007,"journal":{"name":"Journal of Science Natural Science","volume":"79 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77668037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
