The objective of this research was to determine the physicochemical, nutritional and morphological characteristics of five varieties of native fruits from the central Andean region and the northern Peruvian jungle: goldenberry (Physalis peruviana), sanky (Corryocactus brevistylus), cocona (Solanum sessiliflorum), yellow pitahaya (Selenicereus megalanthus) and camu camu (Myrciaria dubia). The fruits were washed, peeled, pulped, fleshed, and lyophilized, to determine, using standardized analytical methods, the nutrient content, such as vitamin C, fiber, soluble solids. The goldenberry, sanky and camu camu fruits presented the highest vitamin C content (43.0, 57.1 and 2,780 mg per 100g of fresh weight, respectively), while cocona and pitahaya had 4.54 and 8.0 mg per 100g of fresh weight, respectively. The goldenberry and pitahaya (26.85 and 9.75%) yielded the highest content of reducing sugars. At the same time, goldenberry and cocona reported the highest fiber values (4.9 and 2.5%, respectively). Regarding the content of soluble solids (°Brix), pitahaya and goldenberry showed the highest values (16.2 and 13.3 respectively). In conclusion, the results obtained show that the native fruits studied represent an important source of nutrients that can be beneficial for human health.","PeriodicalId":41861,"journal":{"name":"Revista Investigaciones Altoandinas-Journal of High Andean Research","volume":"23 1","pages":"17-25"},"PeriodicalIF":0.5,"publicationDate":"2021-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44137845","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}

On the other hand, whey is a residual effluent from the dairy industry generally eliminated in sewage, however, due to its high organic load it can be used to produce different biofertilizers. The objective of this study was to evaluate the effect on the production of the corn crop when applying a biofertilizer obtained by anaerobic fermentation of whey and bovine manure. The study was conducted between October 2018 and February 2019, in the experimental area of the Calaspam association, located in Majes, Arequipa-Peru. A complete randomized block experimental design was used in a 2×4 factorial scheme composed by three biofertilizer treatments (6.9 and 12 LBF/water) and a control treatment with three replicates applied with an average flow rate of 1.5 Lha-1. Morphological, post-harvest and economic indicators were determined, as well as the chlorophyll content. Results indicate that biofertilizer treatments improved the indicators studied. The third treatment shows higher values in all the indicators compared to the other treatments, being the values of yield (79,29±7,33 103 kgha-1) and marginal return rate (85,73%) the most outstanding. It is concluded that the biofertilizer obtained from bovine manure and whey has a positive effect on corn production and its application is economically viable.","PeriodicalId":41861,"journal":{"name":"Revista Investigaciones Altoandinas-Journal of High Andean Research","volume":"64 1","pages":"26-36"},"PeriodicalIF":0.5,"publicationDate":"2021-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84116826","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}

It has undergone dynamic demographictransformations that have led to the colonization of vast areas, through a process of world expansion that has turned it into a cosmopolitanbird. Various factors such as its large size, long-distance flight capacity, its omnivore condition, its opportunistic nature, its remarkableability to adapt to new environments; as well as deforestation and the establishment of grasslands for cattle on a large scale, havecontributed to the expansion of its distribution range. In the present work a historical review of the colonization of the cattle heron iscarried out since its arrival to America. Here we would see how geographic and environmental factors have contributed to the distributionof its populations in different ecosystems ranging from the marine coasts up to 4,400 meters high in the Andes of South America. Aswell, this work highlights the importance of meteorological and genetical tools that provide information about the routes that the specieshas followed in conquering new areas.","PeriodicalId":41861,"journal":{"name":"Revista Investigaciones Altoandinas-Journal of High Andean Research","volume":"22 1","pages":"352–361-352–361"},"PeriodicalIF":0.5,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46454122","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 objective was to determine the citizens’ preference in reducing, recycling,reusing, recovering (4R) and their willingness to pay (DAP) for the elimination of urban waste from the classification level. Theinformation was collected through 406 surveys of heads of households by multiple-stage random sampling, complemented by in-depthinterviews; the method of choice experiments (EE) was used to determine the preference of the public user, using thelogitandmixlogitmodel to estimate the probability of the DAP. The results indicate that 68.72% of users do not recycle any waste, but are predisposedto do so. Of these, 28.72% have a preference for RR (waste collection) with the practice of “4R” for segregation purposes; 28.26% forDR (waste disposal) in sanitary landfill instead of open dumps; 26.08% bet on CR (zero waste) with implication of waste reduction; and16.94% choose Status quo of emotional state of the moment as undecided. In sum, 83.06% of citizens have the DAP in exchange foracceptable human health and socio-environmental well-being. It is concluded that the users of Puerto Maldonado have the willingness topay 122 soles per year, in exchange for the elimination of urban waste, being a leading part of sustainability.","PeriodicalId":41861,"journal":{"name":"Revista Investigaciones Altoandinas-Journal of High Andean Research","volume":"22 1","pages":"329–337-329–337"},"PeriodicalIF":0.5,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48616384","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}
