The survey covered seven Local Government Areas and three ecological zones (lowland forest, freshwater swamp and short mangrove). The surveyed areas were Ikwerre LGA (Isiokpo), Emohua (Rumuji and Ndele), Okrika (Fiberesima Polo, ATC sandfill, Greame Ama), Khana- Ogoni (Bori, Kaani 1), Ogba-Egbema-Ndoni (Omoku), Ahoada East (Ahoada main town, Ikata) and Obio-Akpor (Agbada, Rumuagholu, Rumuesara). The habitats included farmlands, fallow areas, swamps, streams and inundated areas, bush paths, human settlements and forested areas. Visual encounter and acoustic survey methods were used. Nineteen amphibian species were encountered including members of the Arthroleptidae, Bufonidae, Dicroglossidae, Ranidae, Hyperoliidae, Ptychadenidae and Pipidae. Freshwater swamps and short mangrove ecological zones (characterized by human settlements and farmlands) had the lowest diversity of two and five amphibian species, respectively. The highest diversity comprised of eighteen different amphibian species was recorded in forested habitats of the lowland forest/freshwater swamp ecological zone. 569 individuals were collected from lowland forest/freshwater swamp ecological zone; 215 from lowland forest; 60 from short mangrove; and 28 from freshwater swamp ecological zone. Shannon diversity was highest in the lowland/freshwater swamp ecological zone (H=2.12) and lowest in the freshwater swamp zone (H=0.52). It is concluded that a forested habitat comprised of the combination of lowland forest and freshwater swamp ecosystems hosts a greater diversity of amphibian species.","PeriodicalId":102565,"journal":{"name":"Journal La Lifesci","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131507573","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}

Manure fertilizer called biosolid fertilizer. Biosolid fertilizer can increase crop yields and supply nutrients for plants. The use of biosolids for vegetables is considered very good economically. The potential for this biosolid fertilizer is very large applied to vegetable crops to increase vegetable productivity in Bengkulu province. The purpose of this study is to analyze what factors influence the intention to consume vegetables derived from biosolid fertilizer. The study was conducted in several traditional markets in the city of Bengkulu. The traditional markets are Pasar Minggu and Panorama Market. The research location was chosen purposively because the two markets are centers of vegetable sales in the city of Bengkulu. The study was conducted on June 2019. The data collected was analyzed quantitatively (Partial least square) and descriptive approach. The results obtained are Attitude toward the behavior significantly influences the intention to consume vegetables from biosolid fertilizer with a T-count value of 2.170.

Generality determines the basic nature of things, and individuality reveals the differences between things. According to the principle of dialectical materialism, the genes of organisms are divided into two types: General genes and individual genes. Genes shared by all biological individuals are called general genes, and genes unique to each individual organism are called individual gene. And use this classification method to discuss the three basic laws of genetics, heterosis theory and mutual affinity, and population genetics and biological evolution. It is concluded three basic laws of genetics are only relative to individual genes, unit traits controlled by general genes are not restricted by three basic laws of genetics, and the proportion of individual gene and general gene between parents has a decisive influence on the mutual affinity of parents and heterosis of hybrid generation, and the gradual process of the evolution of life from simple to complex, from low-level to high-level, is achieved by that the mutations to generate firstly new individual genes, and then the favorable individual genes are generalized, which the individuality genes are transformed into general genes that the individual characters can be transformed into the common characteristics of the population, and the process of natural selection is just to fix the favorable individual genes, make the traits controlled by them change into the general characteristics of this population, and to eliminate the unfavorable genes, and eliminate the unfavorable traits..","PeriodicalId":102565,"journal":{"name":"Journal La Lifesci","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128279990","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}

Choosing from a wide range of risk management tools can help farmers manage uncertainties and adapt to climate change. However, the choice of adoption of these risk management tools are greatly influenced by a number of factors. An empirical study was conducted to estimate the factors influencing the adoption choice of agricultural risk management tools by farmers in Akwa Ibom State, Nigeria. Multistage sampling procedure was employed to select the representative farmers for the study. Information were elicited from farmers using questionnaires. Factors influencing the adoption of crop diversification, insurance and contract farming were analyzed using multinomial logit approach. Empirical results revealed that the decision to adopt crop diversification and insurance were inversely and significantly affected by age of the farmers. Results further showed that farmers decision to adopt crop diversification and contract farming as risk management tools were positively and significantly influenced by the size of farmland at (p<0.05). Findings also showed that access to weather information and frequency of extension contact significantly influenced farmers decision to adopt crop insurance and crop diversification respectively at 10% level. Result indicates that farmers decision to adopt crop diversification as a risk management tool was positively affected by frequency of extension contact. Promoting efficient and effective extension service delivery, access to weather and climate information and human capital development would be sensible policy options.","PeriodicalId":102565,"journal":{"name":"Journal La Lifesci","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130468161","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}
