We present the characterization of the aquatic environment, riparian ecosystem and macroinvertebrate communities in 7 basins of the west slope of the Yanachaga Chemillén National Park (PNYCh). The CERA protocol, including the Andean Biotic Index (ABI), the Fluvial Habitat Index (IHF), the Andean Creek Index (Qbr-And) were estimated and the combination of these 3 indexes allowed to calculate the Ecological Status Index of Andean Rivers (ECOSTRIAND) at each sampling point. Additionally the FBI and BMWP-Col indexes were calculated. Sampling was carried out in the 7 basins, between 1800 and 2500 meters of altitude, including the upper basins inside the PNYCh, in the middle and lower basins, both in the buffer zone of the park. We found 179 taxa, 66 families and 14 orders in all basins evaluated. Within the PNYCh, the values of IHF and Qbr-And were optimal, but to go down basins, the indexes...

The district of Bagua Grande, province of Utcubamba, Amazonas region, faces a severe noise pollution problem due to its rapid population growth and the consequent increase in vehicular traffic. Factors such as excessive use of horns, the age of the vehicle fleet, and the lack of mufflers intensify the noise, impacting quality of life. The main objective of this research was to evaluate noise pollution in the district and compare sound pressure levels (SPL) with Supreme Decree No. 085-2003-PCM. The methodology used followed the National Protocol for Environmental Noise Monitoring (Supreme Decree No. 227-2013-MINAM). Monitoring was carried out between October and December 2020, during daytime hours (6:00 a.m. to 8:00 a.m. and 12:00 p.m. to 2:00 p.m.). Sixty points (40 urban and 20 commercial) were measured at a height of 1.5 m, totaling 180 measurements. The results concluded that there wa...

El Modelo IVE se ha diseñado para evaluar las condiciones ambientales de las emisiones de fuentes móviles que operan en las ciudades, a la fecha se viene aplicando exitosamente en megaciudades como los Ángeles, Santiago , Kajastán , Nairobi , entre otras , y en el 2003 se aplicó en forma exitosa en la Ciudad de los Reyes, Lima , para ello se realiza las coordinaciones institucionales con la Comisión Nacional de Aire Limpio para apoyar esta iniciativa que planteaban la Universidad de California Riverside y la Universidad de Chile. La metodología IVE se basa en protocolos establecidos como características de conducción, Partidas de vehículos (unidades VOCE), encuestas de flota y videos de los circuitos elegidos, que se cumplieron en forma rigurosa y técnica, lográndose una data valiosa para las simulaciones posteriores de los gases efecto invernadero, de los factores de emisió...

The IVE Model has been designed to evaluate environmental conditions of emissions from mobile sources operating in cities. So far, it is being succesfully applied in megacities such as Los Angeles, Santiago, Kajastan, Nairobi, among others, and in 2003 it was succesfully applied also in Lima, the City of Kings. For that purpose, institutional coordinations are made together with the Clean Air National Committee, in order to support this proposal set upon by Riverside University of California and Universidad de Chile. The IVE methodology is based on established protocols such as conduction characteristics, vehicles startings (VOCE units), fleet surveys and videos of the circuits chosen, which were carried out in a severe and technical way, thus obtaining valuable data for the following simulations of greenhouse gases, emission factors, the behaviour pattern of the whole of vehicles in the...

The white machín, Cebus albifrons, is a neotropical primate belonging to the Family Cebidae, Subfamily Cebinae. The aim of this study was to determine the ultrasound characteristics and the dimensions of the abdominal organs of the white-fronted capuchin in captivity. It was used four intact adult male specimens in captivity at the Huachipa Zoo and three captive specimens at the Parque de las Leyendas Board of Trustees Zoo (an adult male castrated, an adult female and a juvenile male), both institutions in the city of Lima, Peru. The specimens fasted for six hours; then physical and chemical restraint was carried out using the immobilization protocol established by each zoo. The Pie Medical 100 Falco Vet® ultrasound equipment with 7.5 MHz multifrequential convex transducer and ESAOTE MyLab One Vet with the 4-9 MHz SC312 microconvex transducer were used. The ultrasound images are displa...

La Ley Forestal y de Fauna Silvestre en el Perú, permite la caza de subsistencia de la fauna silvestre para autoconsumo y el comercio de pieles por las comunidades locales. Estas pieles son secadas en la modalidad de seco dulce y luego almacenadas en las viviendas de los pobladores hasta su comercialización. Por lo tanto, son altamente manipuladas y expuestas a efectos ambientales diversos. En el estudio se recolectó 300 muestras de pieles, procedentes de tres cuencas de ríos (Amazonas, Napo y Pacaya- Samiria) y se estandarizó un protocolo de extracción del ADN para pieles de Pecari, evaluándose dos métodos de extracción de ADN (Fenol– Cloroformo – Alcohol isoamilico y por columna). Se logró cuantificar el ADN con valores entre 164 y 3461 ng/µL obtenido por el Fenol– Cloroformo – Alcohol isoamilico. Asimismo, se estandarizó un protocolo de PCR para evaluar la eficienc...

Las actividades humanas están produciendo un exceso de gases de efecto invernadero que están potencialmente calentando el clima de la tierra. En tanto que los ecosistemas forestales están almacenando el Carbono de la atmósfera en la biomasa y el suelo. La siguiente investigación, “Evaluación del incremento volumétrico de cinco especies forestales y su almacenamiento de captura de carbono, Centro de Producción e Investigación Pabloyacu, Moyobamba – 2018”, tuvo como objetivo general la evaluación del incremento volumétrico de cinco especies forestales y su almacenamiento de captura de carbono; Eucalipto torrelliana, Eucalipto saligna, Bolaina, Pino chuncho y Tornillo, especies encontradas, en la plantación forestal perteneciente al Centro de Investigación se desarrolló metodológicamente en dos fases, la fase de campo, que se desarrolló por etapas, la etapa de identifi...
