The assignment of accurate species names is crucial, especially for those with confirmed agronomic potential such as highland papayas. The use of additional methodologies and data sets is recommended to establish well-supported boundaries among species of Vasconcellea. Accordingly, six chloroplast (trnL-trnF, rpl20-rps12, psbA-trnH intergenic spacers, matK and rbcL genes) and nuclear (ITS) markers were used to delimit species in the genus Vasconcellea using phylogeny and four DNA-based methods. Our results demonstrated congruence among different methodologies applied in this integrative study (i.e., morphology, multilocus phylogeny, genetic distance, coalescence methods). Genetic distance (ABGD, SPN), a coalescence method (BPP), and the multilocus phylogeny supported 22–25 different species of Vasconcellea, including the following five new species from northern Peru: V. badilloi sp. nov., V. carvalhoae sp. nov., V. chachapoyensis sp. nov., V. pentalobis sp. nov., and V. peruviensis sp. nov. Genetic markers that gave better resolution for distinguishing species were ITS and trnL-trnF. Phylogenetic diversity and DNA-species delimitation methods could be used to discover taxa within traditionally defined species.

Background and Objective: Electromagnetic fields coming from electric and electronic devices, mobile telephony antennas, or electrical installations are continuously growing and are in direct relation with population growth. In that sense, the purpose of this investigation was to determine what are the effects of artificial electromagnetic fields on the behavior and viability of bees through a global perspective . Materials and Methods: The methodology used in this research consisted of the review of literature obtained from platforms such as Scopus, EBSCO, IEEE, Wiley, Google Scholar and Taylor & Francis. Results: It was possible to review 36 studies on the field and to state that investigations on this topic have increased in 2019, at a compounded annual growth rate (CAGR) of 6.86% (in a period of 54 years). Poland and USA are the leading countries in the number and importance of investigations on this topic. Keywords were grouped on the basis of the advancement of the research (honeybee, animals, Apis mellifera and apoideos). Conclusion: The study of the effects of electromagnetic fields on bees makes it possible to understand its impact on the metabolism and viability of bees.

Lessonia spicata (Suhr) Santelices is the most ecologically and economically important kelp from Pacific South America. Here, we contribute to the bioinformatics and evolutionary systematics of the species by performing high throughput sequencing on L. spicata from Valparaiso, Chile. The L. spicata complete mitogenome is 37,097 base pairs (bp) in length and contains 66 genes (GenBank accession MK965907), the complete plastid genome is 130,305 bp and has 173 genes (accession MK965908), and the data assembled 7,630 bp of the nuclear ribosomal cistron (accession MK965909). The organellar genomes are similar in structure and content to others published from the Laminariales.

On March 16, 2020, a policy of quarantine and social isolation initiated in Peru imposed by the declaration of National Public Health Emergency for Severe Acute Respiratory Syndrome (SARS-CoV-2), which is affecting everyone. The research aimed to collect information that anticipates the impacts on the quantity and the need to distribute food for food security. From a global point of view, fiscal, monetary, and macro-financial policies corresponding to approximately 7% of the National GDP. These efforts will be insufficient if they are not complemented by adequate planning to supply the needs of Peru with at least 484,402.1 kilos of food per month, concerning agricultural products contained in the index basket and that need to be distributed in all regions of the country, such as rice, potatoes and at least 14 other products. In conclusion, measures in four aspects are urgent: technological, scientific, humanitarian, and planning, in addition to those implemented, to mitigate the impacts on food security, now and postpandemic, it is suggested that the issue should be treated from a transdisciplinary perspective.
