    The objective of the research was to evaluate the effect of geographic altitude on the carbon stock in two physiographic units of the Reserved Forest of the Universidad Nacional Agraria de la Selva, Tingo Maria-Huanuco. The methodology used was the field manual for the remeasurement and establishment of plots of the Amazon Forest Inventory Network (RAINFOR), for which 2 hectares were permanently established (one hectare in low and high hills) in which the diameter (greater than or equal to 10 cm) and the height of the trees were measured. Finally, the density of the wood was obtained from previous studies. The pantropical model formula was used to estimate the carbon stock. The results show that geographic altitude significantly affects carbon stock (p < 0.05) in low and high-hill forests, concluding that this may be due to differences in meteorological variables such as precipitation, temperature, and humidity.

    In Peru, scientific journals are in constant growth, as they seek to make visible the scientific work of licensed public universities. In this sense, the objective of this research was to evaluate the historical evolution and future perspectives of scientific journals in Peru. The research was carried out by reviewing the official web pages of each institution, taking into account the official list of universities authorized by the Superintendencia Nacional de Educación Superior Universitaria (SUNEDU). We reviewed journals that are included in the Sistema Regional de Información en Línea para Revistas Científicas de América Latina, el Caribe, España y Portugal (Latindex Catálogo 2.0), SciELO, Web of Science (WOS) and Scopus. Data analysis was performed by tabulation in Excel and Minitab 19. We found 205 scientific journals, 51 are indexed in at least one database (Latindex Catálogo 2.0, SciELO, WOS, or Scopus) and 154 in no database, which means that the editorial teams have an arduous task. Only four journals are indexed in Scopus (three belong to the Universidad Nacional Mayor de San Marcos and one to the Universidad Nacional de Trujillo). It is concluded that the evolution of the journals is a function of their Google Scholar H index. Likewise, support for public universities should be increased to promote the indexing of scientific journals to generate greater visibility of research at regional, national, and international levels of public universities in Peru. In this sense, future perspectives include incentive policies for researchers who publish in local journals.
