La presente investigación tuvo como objetivo analizar el estado actual, flora asociada, intervención antropogénica y zonificación del bosque de Polylepis en el Departamento de Moquegua, distrito de San Cristóbal C.P.M. de Muylaque. Se establecieron parcelas de 25 x 20 m. (0,05 ha.); ubicado al azar para luego levantar información del estado actual del bosque. En una área de 796 Has; La estructura poblacional predomina los latizales con 239 individuos (39%), muy seguida de los individuos adultos con 217 individuos (35%) y con menor cantidad los brinzales con 164 individuos (26%). Se encontraron un total de 73 especies distribuidas en 28 familias, constituidas por especies herbáceas y arbustivas, las más representativas son P. lucida, F. orthophylla, A. spinosissima, A. adenophylloides, S. boliviensis, S. neoviscosus, G. longistyla, S. ichu, F. ortophylla, Poa annua, Stipa obtusa,...

The objective of this research was to quantify the contents of aboveground biomass and carbon of Polylepis spp. “queñoa”, in a relict forest of the Muylaque countryside community in the department of Moquegua between 3,700 and 4,300 m.a.s.l. Under a forest inventory, dasometric parameters (stem diameter, crown diameter, total tree height) were recorded in 20 × 20 m plots, following MINAM (Peruvian Ministry of the Environment) guidelines, to then calculate biomass through the application of an allometric equation for Polylepis and the conversion factor obtained from samples of 20 individuals with the photometric method to find the stored carbon. The laboratory results showed that the conversion factor from biomass to stored carbon was 0.58. In addition, using the information per plot in the forest inventory and applying the allometric equation, the expansion factor per hectare a...

Shepherds intentionally burn certain high Andean grasslands to stimulate the regrowth of grass. Nevertheless, this practice results in the generation of Polycyclic Aromatic Hydrocarbons (PAHs), which contaminate and can leach into the soil and be absorbed by plants. Ultimately, this adversely affects the livestock graze on these contaminated plants. The objective of this study was to evaluate the presence of 15 PAHs at the surface, 10, 20, and 30 cm depth, immediately and three months after burning natural grasses in Somoa, Carumas-Peru, during the year 2021. UHPLC-FLD determined PAHs, and the QuEChERS method was used to extract the PAHs from soil samples. Twelve of the 15 PAHs listed by the USEPA were found. The highest concentration was found at the surface, followed by the 10, 20, and 30 cm (759,63, 157,99, 85,86, and 68,04 ng g−1, respectively). On the other hand, Acenaphthene pres...
