There are many native fruits in Peru containing essential nutrients for health and that have not been fully studied. 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.

Corn (Zea Mays) is the most cultivated cereal in the world and this is a staple food for human beings that is why in recent years they are looking for alternatives to improve their production. 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.

The cattle heron is native of the tropical and subtropical areas of Africa and Asia, from where it arrived on the northeast coast of SouthAmerica in 1877 and extended its distribution range to Central America and North America. 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.

The objective of the present study was to evaluate the etiolated adventitious shoot regeneration for the development of anin vitropropagation protocol of threeRubussp. cultivars. Zygotic embryos were extracted from botanical seeds ofRubussp. cultivars andplaced in establishment culture medium. After 90 days ofin vitroculture, the seedlings were conditioned to obtain the basal stemsegments and placed in growth and development culture media, they were then subjected to periods of darkness for etiolated adventitiousshoot regeneration. Afterwards, the nodal segments were transferred to rooting culture media. Results showed that the regeneration ofadventitious shoots fromRubussp. cultivars was on average eight days. Likewise, the sectioned nodal segments of the adventitious shootsinduced roots when the medium contained the combination of the auxins NAA and IBA. The regeneration of etiolated adventitious shootsin the three cultivars ofRubussp. allowed to obtain elongated shoots in a short time and without the use of growth regulators, facilitatingthein vitropropagation of this species

Information on the thermal preference of bats goes back to studies carried out since the middle of the 20th century, mainly in NorthAmerica and Europe. Here we present information on the thermal preference of six bat species in the cloud forests of the HistoricSanctuary of Machu Picchu (Cusco, Peru). The data were obtained in field using a thermographic camera and an infrared thermometer.Our results show the intervals and averages of the selected temperatures, as well as the differences between sexes of each species. Thisinformation constitutes the first effort in Peru to understand the temperature ranges that natural and artificial bat refuges should have.

Mountain regions face decisive challenges, not only for their sustainable development but also fortheir very reproduction. These challenges have to do with the increasingly serious impact of climate and environmental change, the impact of socioeconomic and cultural globalization on mountain populations and the ecosystems they inhabit, and the effects of urbanization on mountain agriculture. Based on these premises, this article introduces the notion of “montology” by investigating, on the one hand, the historical development of the term and, on the other, by presenting the essential principles of a perspective committed to building a real transdisciplinarity in mountain studies. Finally, through the example of urbanization and its impact on Andean agriculture, we intend to highlight the need to adopt a montological perspective in order to contribute to the analysis of human environmental problems and to the sustainable development of the region.

Currently, there are no studies on the cultivation of quinoa (Chenopodium quinoa) in Peru related to the reaction ofMeloidogynespp. Thisstudy aimed to evaluate the reaction of five quinoa cultivars (‘Salcedo INIA’, ‘Choclito’, ‘Huariponcho’, ‘Negra Collana’, and ‘Kcancolla’)toMeloidogyne arenaria, Meloidogyne incognita,andMeloidogyne hapla. The experiment was carried out using a completely randomizeddesign, with five quinoa cultivars and three species ofMeloidogynespp. with six repetitions. Quinoa plants were kept in a mesh house andplaced in polyethylene bags with 3,000 dm³ of sterile soil inoculated with 5,000 eggs + juveniles (J2). After 90 days of inoculation, thenumber of nematodes per gram of root, number of galls, and the reproduction factor (final population/initial population) were determined.All quinoa cultivars were susceptible toM. incognitaand resistant toM. arenariaandM. hapla,except for ‘Negra Collana’, which wassusceptible toM. arenaria, and ‘Salcedo INIA’ and ‘Huariponcho’, susceptible toM. hapla.

The study was carried out at the La Raya Experimental Center of the National University of the Altiplano of Puno at an altitude of 4200m,with the aim of evaluating the effect of additional post-ovulation copulations on embryonic survival. Huacaya alpacas were used withpostpartum sexual rest greater than 20 days, with a preovulatory follicle greater than 7 mm, verified by ultrasound. For the controlledmating, 5 males from the breeding group were used. After breeding, 26 to 35 hours post-mating, ovulation was verified, selecting 47alpacas that ovulated, and distributed to the experimental groups: G1 (n = 16) with no additional mating, G2 (n = 15) received anadditional mating 24 hours post-ovulation, and G3 (n = 16) two additional mating 48 hours post-ovulation. On days 14 and 24 aftercopulation, the presence of the corpus luteum and embryonic vesicle was verified by ultrasound and receptivity of the female to the male.Results show a higher percentage of embryo survival trend in alpacas that received additional mating at 24 and 48 h post-ovulation thanthose that received only one ovulatory mating, showing at 14 days post-copulation an embryonic survival of 93.3% and 87.5%, in G2and G3 respectively, compared to G1 with 75%, and at 24 days post-copulation 86.7% and 87.5% in G2 and G3 respectively, comparedto G1 (62,5%). Although no significant differences were observed between groups (P>0.05), the difference is observed in the simplecorrespondence analysis between groups.

The management of urban waste in the Provincial Municipality of Tambopata induces the environmental deterioration of the soil, water,and biodiversity along with the proliferation of diseases. 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.
