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 surrounding areas and ecoregions, except for five NPAs. Of the 41 NPAs, nine were non-effective (EI≤3), 31 moderately effective (3
Habitat Suitability Distribution of Genus Gynoxys Cass. (Asteraceae): An Approach to Conservation and Ecological Restoration of the Andean Flora in Peru.

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.
Human-wildlife interaction, conflict, and coexistence: Bibliometric analysis from Scopus (1987–2023)
(Malque Publishing, 2025-07-18) Guzman Valqui, Betty Karina; Silva López, Jhonsy O.; Rojas Briceño, Nilton B.
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 the field, although newer specialized journals are gaining visibility. Predominant research topics include carnivore–livestock conflicts and species conservation. However, new areas of interest are emerging, including urban wildlife interactions and the sociocultural aspects of coexistence. This study offers an updated overview of the evolution of HWCICx research and highlights the need for integrated natural and social science approaches to develop sustainable models of coexistence.
Manejo integrado de mosca blanca en el cultivo de palto en Moquegua
(Instituto Nacional de Innovación Agraria (INIA), 2025-12-30) Guerrero Tafur, Lorenzo; Espinoza Rojas, Merlyn; Guzman Valqui, Betty Karina
Las moscas blancas (Familia: Aleyrodidae) de las especies Aleuropleurocelus sp. y Paraleyrodes sp., son las principales plagas que afectan al cultivo de palto en Moquegua. Son insectos pequeños, de apenas 1 a 3 mm de tamaño, los adultos tienen el cuerpo y las alas cubiertas por un polvillo ceroso de color blanco, que puede estar protegiendo los huevos o estados inmaduros. La hembra pone los huevos en el envés de las hojas. Dependiendo de la especie, el clima y la planta de la cual se alimentan, puede poner desde 48 hasta 500 huevos. Su ciclo de vida es corto, en promedio 28 días (Ortega-Arenas y Carapia-Ruiz, 2020 citando a Butler 1982; Byrne et al. 1990; Gill 1990; Byrne y Bellows 1991), lo que favorece su rápida reproducción y dispersión en los cultivos de palto.
Manejo integrado de queresas en el cultivo de limón sutil en Moquegua
(Instituto Nacional de Innovación Agraria (INIA), 2025-12-30) Guerrero Tafur, Lorenzo; Espinoza Rojas, Merlyn; Guzman Valqui, Betty Karina
El limón sutil (Citrus aurantifolia) es una variedad de lima ácida muy apreciada en la gastronomía peruana. Se reconoce por sus frutos pequeños, de cáscara delgada, pulpa jugosa, muy ácida y con un aroma intenso. En la región Moquegua aún no hay grandes extensiones cultivadas, pero en los últimos años su producción se ha venido incrementando. Este cultivo tiene un gran potencial, ya que puede convertirse en una alternativa rentable, tanto para el mercado nacional como para el internacional. En la Estación Experimental Agraria Moquegua se ha instalado una parcela demostrativa de limón sutil con el objetivo de mostrar el manejo adecuado de este cultivo y promover su producción. Con la finalidad de fortalecer la iniciativa productiva de los agricultores locales, se pone a disposición los principios básicos para el manejo integrado de las queresas que afectan a este cultivo en la región. Este manejo se basa en el uso de métodos combinados, compatibles, rentables y respetuosos con el ambiente.
