Performance of hybrid diffuse reflectance spectroscopy (HDRS‐ISO 23698) methodology for assessment of sunscreen protection in the ALT‐SPF Consortium validation study

open access: yesInternational Journal of Cosmetic Science, Volume 47, Issue S1, Page 53-77, September 2025.
Hybrid Diffuse Reflectance Spectroscopy (HDRS), now ISO 23698, demonstrated bioequivalence to gold‐standard SPF, UVA‐PF, and CW methods, achieving similar accuracy with improved variability after training. This new non‐erythemal approach enables safe non‐invasive sunscreen performance assessment on human skin, expanding possibilities for evaluating ...

Ruminant feces used as inoculum for the in vitro gas production technique Heces de rumiantes como fuente de inóculo para la técnica in vitro de producción de gases Fezes de ruminantes como fonte de inoculo para a técnica in vitro de produção de gases

open access: yesRevista Colombiana de Ciencias Pecuarias, 2012
Background: ruminal feed fermentation can be studied through in vitro gas production. However, this technique requires fistulated animals from which to obtain the inoculum, which limits its use. Objective: the objective of this experiment was to evaluate

Validation of Body Condition Scoring as a Screening Test for Low Body Condition and Obesity in Common Marmosets (Callithrix jacchus)

open access: yesAmerican Journal of Primatology, Volume 87, Issue 8, August 2025.
We tested the performance of body condition scoring (BCS) as a screening tool for detecting low body condition and obesity in marmosets, by comparing its results against measurements of body composition performed with quantitative magnetic resonance.

Estimating abundance of aggregated populations with drones while accounting for multiple sources of errors: A case study on the mass nesting of Giant South American River Turtles

open access: yesJournal of Applied Ecology, Volume 62, Issue 8, Page 2036-2047, August 2025.
The developed approach can be applied to several contexts to efficiently survey spatially aggregated populations using drone‐derived orthomosaics, and to understand phenology at these aggregation sites. We provide general recommendations for planning surveys and discuss implementations of our approach using other types of marking methods and model ...

Incorporating citizen science into IUCN Red List assessments

open access: yesConservation Biology, Volume 39, Issue 2, April 2025.
Abstract Many citizen scientists are highly motivated to help address the current extinction crisis. Their work is making valuable contributions to protecting species by raising awareness, identifying species occurrences, assessing population trends, and informing direct management actions, such as captive breeding.
