Bird censuses in Peru began in the early twentieth century with seabird censuses carried out by the Compañía Peruana del Guano and later by IMARPE. Between 1992 and 2016 annual censuses were carried out, in 61 wetlands, in 12 departments of Peru, recording a total of 151 species between resident and migratory. The censuses constitute a great contribution to the knowledge of waterbird species and to the synergies between institutions and ornithologists who, through volunteering, compile important information for species conservation and wetland management in the Andean slopes. The taxonomic composition of the species, the importance of censuses, the migration routes of birds from the Nearctic, southern and high Andean regions, and the protected areas in the conservation of wetlands and biodiversity are analyzed. The aim of this paper is to carry out a historical analysis of the censuses and their contribution to the knowledge of waterbirds carried out in the last three decades with special reference to the conservation of wetlands in the Andean slopes in Peru.

In recent decades, the increase in stress levels of university students has been seen as a serious threat. Due to this problem, the present investigation has been focused on studying how time management is linked to academic stress in university students. This research study of a basic/substantive non-experimental type and correlational level has been developed under a quantitative approach with a cross section. The sample consisted of 328 students of both genders, selected from a public university in the city of Lima. Two standardized tools were adapted for data collection. Two questionnaires were also applied: time management and academic stress. The results showed that there was an inverse correlation between time management and academic stress (Spearman's Rho = .413), as well as for the dimensions of academic stress: stressors (- .405), symptoms (-, 387) and coping (, 286). It was concluded that the inverse relationships between the parameters studied will be reflected in the values obtained. Furthermore, possible measures to mitigate the casuistry around academic stress are also discussed.

Decades ago, technology was seen as something futuristic, today we are facing a new learning reality: virtuality. This systematic review article aims to determine the importance of providing answers to the existing inequality in many of the homes where a student is found without internet and without technological tools that lead to the new paradigms of learning based on computational means. research, a descriptive systematic review and qualitative approach was used, which is achieved using the methodology of searching for information from the articles, with the Prism method, obtaining the information in the different repositories in which these investigations are deposited, such as Scopus, Scielo, Redaly or World wid Escience. Significant learning shows the relevance and significance of studying educational inequalities and the skills acquired by few students according to their economy.
