En la presente investigación se ha evaluado la calidad del agua de la cuenca del río Utcubamba en base a parámetros biológicos como es el uso de Diatomeas (bacillariophyceae). Para ello, se realizaron dos muestreos, en época seca (octubre 2014) y húmeda (marzo 2015), en 43 estaciones de muestreo ubicadas a lo largo de la cuenca del río, situadas entre 386 (9386480N y 770597E) y 2834 (9244491N y 191314E) m.s.n.m. dividiendo la cuenca en alta, media y baja de acuerdo al piso altitudinal donde se encuentran. Para dicha evaluación se usó como herramienta principal el Índice de diversidad de Shannon & Wienner (H') para Diatomeas. Los resultados de la aplicación de los Índice de diversidad de Shannon & Wienner (H') indican que en la cuenca del río Utcubamba el agua presenta una Contaminación Moderada para el tramo alto de la misma, y una Contaminación Leve en los tramos medio y ...

Representar la mayor cantidad de valores de los ecosistemas en términos económicos siempre ha sido un desafío para los métodos valorativos, considerando sus limitaciones inherentes. Choice Experiment (CE) y Analytic Hierarchy Process (AHP) son técnicas que destacan por su capacidad para representar preferencias teóricas e individuales sobre los atributos de los ecosistemas. En esta investigación se integró ambas técnicas con el objetivo de asignar valor económico (VE) a la mayor cantidad posible de servicios ecosistémicos (SE) de los Bosques Secos del Marañón (BSM). Para este propósito, se utilizó CE para estimar la disposición a pagar (DAP) de cuatro SE de la ecorregión BSM, recursos genéticos, provisión de agua, ecoturismo y formación del suelo. CE fue ejecutado mediante tarjetas de elección a 285 jefes de hogar en la provincia de Cutervo, departamento de Cajamarca...

Human interactions with wildlife range from conflict (negative) to coexistence (positive or neutral). The scientific interest in this topic is increasing rapidly, although the terminology used varies among authors. This study presents a bibliometric analysis of literature on human–wildlife interaction, conflict, and coexistence (HWCICx) from 1987 to October 2023 using Scopus data analyzed with VOSviewer and the Bibliometrix package in R. An exponential rise in publications was identified between 1995 and 2022, confirming HWCICx as an emerging yet robust research field. The United States and the United Kingdom lead in publication volume and international collaboration, whereas researchers from Asia and Latin America show growing involvement. Journals specializing in ecology, conservation, and wildlife, such as Biological Conservation, Oryx, and Human–Wildlife Interactions, dominate th...

Peruvian Amazonian Forests (PAF), vital for biodiversity, climate, and human well-being, lost 2.92M ha during 2001-2022, mainly due to anthropogenic activities. This prompted strategies to conserve and protect the PAF, such as land use and natural resource restrictions, with natural protected areas (NPAs) being the main strategy. This study evaluated the effectiveness of 41 NPAs in containing deforestation in the PAF by analyzing national spatial data. An Effectiveness Index (EI) was constructed by adding five standardized parameters: (1) the percentage of deforested area (DA%) and (2) its annual rate of change (DAr) between 2000 and 2022 inside each NPA, (3) the difference in DAr between NPAs and their surrounding areas, (4) their corresponding ecoregions, and (5) the entire PAF. In 2000, the DA% was 7.15% of the PAF, increasing to 10.88% in 2022. NPAs showed lower DAr than their surrou...

The study used species distribution models (MaxEnt) to analyze the ecological suitability of the genus Gynoxys in Peru. Bioclimatic, edaphic and topographic variables were integrated to predict areas with high development potential. Potential distribution maps were generated, and model validation showed outstanding performance (AUC > 0.9). The results indicated that variables such as minimum temperature in the warmest season and soil moisture are determinants in the distribution of the Discoide, Gynoxys and Praegynoxys clades. It is concluded that the conservation of the genus requires protection strategies to ensure the sustainability of these montane ecosystems.
