Ante la falta de herramientas de evaluación de la calidad ecológica en sistemas fluviales lóticos del área andina situados por debajo de los 2000 m.s.n.m., el objetivo principal de este estudio fue desarrollar un índice para la valoración de este tipo de ríos, situados además como el Utcubamba en un valle interandino englobado en el ecosistema de bosques tropicales estacionalmente secos. Se realizaron salidas durante dos temporadas hidroclimatológicas, época de lluvia tempranas en octubre de 2014 y época seca en agosto de 2015. Se establecieron 43 puntos de muestreo a lo largo del cauce principal y tributarios más importantes desde su nacimiento a su desembocadura. Se contabilizaron 63 familias distribuidas en siete clases y 20 órdenes. Asimismo se determinaron 19 parámetros fisicoquímicos y microbiológicos, cuyos valores obtenidos se emplearon para la búsqueda de las fu...

            The veterinary use of medicinal plants practiced by the population of two cattle regions in the montane forests of northern Peru were compared. The objectives of the study were: (1) to collect information on veterinary uses and medicinal plants typical of two cattle regions in the Amazonas Department: Leimebamba and Molinopampa districts; (2) evaluate the influence of socioeconomic factors on veterinary knowledge about medicinal plants; (3) understand the transmission of traditional knowledge between age groups (18-30, 31-40, 41-50, 51-60, >60 years). Semi-structured interviews were carried out (n=120), complementing ethnobotanical questions on socioeconomic aspects. The weight of the socioeconomic factors in the knowledge about medicinal plants and veterinary uses of each basin was done through a multidimensional scal...

Cattle ranching is a fundamental economic activity in northern Peru, where proper management of water resources is crucial. This study, a pioneer in the region, evaluated water quality and its suitability for human consumption, vegetable irrigation, and livestock production. It is also the first study to document the presence of metals and metalloids in vulnerable areas because they are located at the headwaters of river watersheds. The spatiotemporal evaluation of physicochemical parameters, metals, and metalloids was performed in five micro-watersheds (Cabildo, Timbambo, Pomacochas, Atuen, and Ventilla) from water samples collected in the dry season (October 2017) and wet season (March 2018). The parameters were analyzed using microwave plasma atomic emission spectrometry. The results were contrasted with international and Peruvian quality standards related to dairy cow production. The...
