Ilustrar de forma sencilla y práctica la identificación taxonómica de especies forestales con diámetro a la altura del pecho (DAP) ≥ a 10 cm del arboreto “El Huayo”. Los contenidos descritos en este libro, permitirán un mejor conocimiento de la biodiversidad amazónica y será insumo para estudios científicos, así como estudiar la estructura, composición y función del bosque, las relaciones ecológicas existentes, además de las prácticas de los docentes y estudiantes de pre y post grado que permitirá un mejoramiento de la calidad de la enseñanza en la Universidad Nacional de la Amazonía Peruana.

Se evaluó la supervivencia e insectos plaga de especies forestales y frutales en Puerto Almendra, Loreto, Perú. Se obtuvieron plántulas y estacas de 15 especies forestales y de 04 especies frutales, a partir de poblaciones naturales y huertos familiares; estas fueron instaladas en parcelas de 25 x 25 m, 25 individuos por especie. Las estacas de Spondias purpurea tuvieron mayor supervivencia (84%), Spondias mombin y Spondias dulcis alcanzaron 36% y 24% respectivamente. Las plantas provenientes de semillas botánicas con muy buena supervivencia (80‑100%) fueron Copaifera paupera, Dipteryx odorata, Carapa guianensis, Swietenia macrophylla, Hura crepitans, Chorisia integrifolia, Spondias mombin, Guazuma ulmifolia, Pleurothyrium parviflorum, Amburana cearensis. Con buena supervivencia (60‑79%) se encuentran Cedrelinga cateniformis, Cedrela odorata y Genipa americana. En la categor�...

Survival and insect pests of forest and fruit species in Puerto Almendra, Loreto, Peru were evaluated. Seedlings and cuttings of 15 forest species and 04 fruit species were obtained from natural populations and home gardens; these were installed in plots of 25 x 25 m, 25 individuals per species. Spondias purpurea cuttings had the highest survival (84%), Spondias mombin and Spondias dulcis reached 36% and 24% respectively. Plants from botanical seeds with Very good survival (80‑100%) were Copaifera paupera, Dipteryx odorata, Carapa guianensis, Swietenia macrophylla, Hura crepitans, Chorisia integrifolia, S. mombin, Guazuma ulmifolia, Pleurothyrium parviflorum and Amburana cearensis. With Good survival (60‑79%) are Cedrelinga cateniformis, Cedrela odorata, Genipa americana. In the category Regular (40‑59%) are Caryodendron orinocense y Calycophyllum spruceanum. In the category Bad (&...

The use of soil to implement several management systems, such as agriculture, livestock farming and agroforestry activities contribute to the depletion of the soil and the forest, reducing or increasing the levels of soil chemical attributes, such as calcium, magnesium, potassium, and phosphorus and increase or decrease of active (pH) or exchangeable (Aluminum) acidity. This study aimed to evaluate macronutrients (calcium - Ca2+, magnesium - Mg2+, potassium - K+ and phosphorus - P), as well as aluminum - Al3+ and soil pH, under use systems: agroforestry system - SAFs and pasture - PA, comparing them to Primary Forest - PF, in the Rosenthal community in Itacoatiara-AM, Brazil. The soils were sampled in layers 0-10 cm and 10-20 cm deep, with samples composed of six single samples each. The distribution of nutrient contents (Ca2+, Mg2+, K+ , and P) considering the 0-10 and 10-20 cm layers s...
