Global camera trap synthesis highlights the importance of protected areas in maintaining mammal diversity

open access: yesConservation Letters, Volume 15, Issue 2, March/April 2022., 2022
Abstract The establishment of protected areas (PAs) is a central strategy for global biodiversity conservation. While the role of PAs in protecting habitat has been highlighted, their effectiveness at protecting mammal communities remains unclear. We analyzed a global dataset from over 8671 camera traps in 23 countries on four continents that detected ...

Evaluating elicited judgments of turtle captures for data‐limited fisheries management

open access: yesConservation Science and Practice, Volume 2, Issue 5, May 2020., 2020
Abstract We compare judgments of green turtle (Chelonia mydas) captures elicited from local gillnet skippers and not‐for‐profit conservation organization employees operating in a small‐scale fishery in Peru, to capture rates calculated from a voluntary at‐sea observer program operating out of the same fishery.

Spatial Variation of Acidic Sodic Soils in High‐Andean Environments and Theoretical Estimation of Gypsum Requirement

open access: yesSoil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT High‐Andean forage systems are characterized by extensive management of cultivated forages, primarily through rotation of forage oats (Avena sativa) and alfalfa (Medicago sativa), under marginal edaphoclimatic conditions. Within this context, soil sodicity severely constrains the productivity of these systems in the districts of Ayaviri and ...

Spatial Assessment of Heavy Metal Contamination in Agricultural Soils of the Lower Chancay–Huaral Valley, Peru

open access: yesApplied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Soil contamination by heavy metals (HMs) poses a potential threat to agricultural productivity and food security, particularly in rapidly developing coastal regions. This study evaluates the spatial distribution and contamination levels of cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn), and manganese (Mn) in agricultural soils from the Huaral, Chancay,

Soil Organic Carbon Variability in Tropical Cropping Systems: Interactions With Texture, pH, Macronutrients, and Organic Matter

open access: yesInternational Journal of Agronomy, Volume 2026, Issue 1, 2026.
Soil organic carbon (SOC) plays a crucial role in mitigating climate change and enhancing soil fertility. Its storage and dynamics are particularly significant in agricultural ecosystems of the Peruvian Amazon, where the expansion of agriculture and livestock farming may disrupt the regional carbon balance.

Biochar‐Amended Soils: A Water‐Saving Strategy for Quinoa Cultivation in the Andes

open access: yesJournal of Sustainable Agriculture and Environment, Volume 4, Issue 1, March 2025.
ABSTRACT Introduction Previous studies showed that biochar amended soils significantly enhanced the growth and yield of quinoa under water limitations. So it becomes an emerging agronomic strategy to consider for sustainable quinoa production. Biochar can specifically be considered for the area particularly receiving low annual rainfall and more ...

Modeling the current and future habitat suitability of Neltuma pallida in the dry forest of northern Peru under climate change scenarios to 2100

open access: yesEcology and Evolution, Volume 14, Issue 8, August 2024.
The objective of this research was to evaluate the current and future distribution and conservation status of Neltuma pallida in the Peruvian dry forest under climate change scenarios over the last few years. The findings indicated that the likely range of habitats for N. pallida was shaped by factors such as the average temperature of wettest quarter,
