A preliminary floristic inventory is provided for the Huaripampa and Santa Cruz streams in the Santa Cruz, Huaripampa and Llanganuco route at the Huascarán National Park, located among the Provinces of Huaylas and Yungay, Deparment of Ancash, Peru. This circuit presents a high concurrence of national and foreigner tourists. It is notable for its landscape scenery, its biological structure and its proximity to the mountains Alpamayo, Artesonraju, Yanapaccha, Pisco, Huascarán and Huandoy. The floristic listing of flowering plants includes 43 families, 98 genera, 139 species and 11 morphospecies that have been identified.

La presente investigación tuvo por objetivo determinar la relación existente entre el clima social escolar y la procrastinación en estudiantes de secundaria de dos instituciones educativas estatales de Trujillo. El diseño de investigación fue no experimental, de tipo transversal correlacional. La muestra estuvo conformada de 400 estudiantes de secundaria de 2do al 5to año, con un rango de edad entre 12 y 17 años. Los instrumentos utilizados fueron la Escala de Clima social escolar (CES) y la Escala de Procrastinación Académica (EPA). Los resultados fueron obtenidos mediante el coeficiente de correlación no paramétrica Rho de Spearman, hallándose relación entre las dimensiones de la variable clima social escolar y la dimensión Autorregulación académica de la variable procrastinación (rs=.15), siendo esta directamente proporcional, además se encontró una relación invers...

Polylepis woodlands are a vital resource for preserving biodiversity and hydrological functions, which will be altered by climate change and challenge the sustainability of local human communities. However, these highaltitude Andean ecosystems are becoming increasingly vulnerable due to anthropogenic pressure including fragmentation, deforestation and the increase in livestock. Predicting the distribution of native woodlands has become increasingly important to counteract the negative effects of climate change through reforestation and conservation. The objective of this study was to develop and analyze the distribution models of two species that form extensive woodlands along the Andes, namely Polylepis sericea and P. weberbaueri. This study utilized the program Maxent, climate and remotely sensed environmental layers at 1 km resolution. The predicted distribution model for P. sericea i...
