Using our newly proposed MSCA (Multivariate Similarity Clustering Analysis) method, 7,591 species of modern terrestrial mammals belonging to 1,374 genera in 162 families and 2,378 species of mammals in the Wallace era before 1876 are quantitatively analyzed, and almost the same clustering results are obtained, with clear levels and reasonable clustering, which conform to the principles of geography, statistics, ecology and biology. It not only affirms and supports the reasonable kernel of Wallace’s scheme, but also puts forward suggestions that should be revised and improved. The large or small differences between the clustering results and the mammalian geographical zoning schemes of contemporary scholars are caused by different analysis methods, and they are highly consistent with the analysis results of chordates, angiosperms and insects in the world analyzed by the same method. Once again, it confirms the homogeneity of the global biological distribution pattern of major groups, and the possibility of building a unified biogeographic zoning system in the world.","PeriodicalId":58493,"journal":{"name":"环境科学与工程:B","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44520730","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}

A total of 132 laying quails were arranged in a completely randomized design with 3 treatments and 4 replicates, each replicate being 9 female quails and 2 male quails at 59 days of age. The experimental treatments were as follows: control fed the basal diet (KPCS), E125C75 including KPCS supplemented with 125 mg vitE/kg feed combined with 75 mg vitC/kg feed and E125C125 including KPCS supplemented 125 mg vitE/kg feed combined with 125 mg vitC/kg feed. Research results showed that the highest WG (Weight Gain) was in E125C125 (30.32 g) and lowest in E125C75 (17.37 g). There were no statistically significant differences between treatments in terms of laying rate, feed conversion ratio, egg mass and egg weight. However, hatching rate and bodyweight of quails at 1 day of age were significantly different between treatments, the highest was E125C125 (74.37% and 7.43 g), followed by E125C75 (70.02% and 7.03 g) and the lowest was control (65.89% and 6.82 g). It can be concluded that E125C125 not only improved laying rate but also increased hatching rate and bodyweight of quail chick.","PeriodicalId":58493,"journal":{"name":"环境科学与工程:B","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47606298","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}

However, because people ignore the impact of the moon’s activity on the earth’s climate change on a small scale, they are baffled and helpless when they face the severe problem of global warming. Therefore, the author analyzed various factors affecting global climate change, and found that due to the retreat of polar glaciers, the moon gradually approached the earth. The moon can not only pour more airflow out of the polar vortex, blow out larger ozone holes in the stratosphere, and blow away more clouds in the troposphere, exposing a wider space, letting the sun shine strongly, thus warming these places, but also pull on more clouds, making many places covered by the clouds originally be exposed to stronger sunlight, thus becoming warmer. In addition, the author also found that the proximity of the moon to the earth will also cause changes in the earth’s environment. Therefore, the author clearly put forward reasonable countermeasures to prevent global warming and environmental change.","PeriodicalId":58493,"journal":{"name":"环境科学与工程:B","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46109072","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}

Tabenken is one of the three areas in the continental sectors of the CVL (Cameroon Volcanic Line) where coal occurs in between a granitic basement and volcanic outpours. Samples of coal from this seam were studied to determine the organic matter richness, maturity, depositional environment and its age through organic geochemical techniques such as Rock-Eval pyrolysis and palynological studies. HI (Hydrogen Index) obtained is less than 200 mgHC/gTOC for most of the samples indicating Type III kerogen for these samples (gas prone) and terrestrial source of the original peat-forming organic matter. One sample presents a HI of 462 mgHC/gTOC indicating organic matter type II, prone to producing oil. Palynological studies reveal the presence of hydrogen-rich AOM (Amorphous Organic Matter) indicating preservation under dysoxic-anoxic conditions. High values of TOC ranging from 0.29 to 1.98 are suggestive of AOM of terrestrial origin. The remarkable absence of pollen suggestive of deposition before the Pennsylvanian during which the earliest forms of flowering plants first appeared displays a relative abundance of spores in the organic residue suggestive of deposition from the mid-Ordovician. Careful interpretation of palynological data suggests the coal was laid down from the mid-Ordovician to the Pennsylvanian age.","PeriodicalId":58493,"journal":{"name":"环境科学与工程:B","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41518054","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}
