Livelihood resilience: The role of social‐ecological filters in a Globally Important Agricultural Heritage System of southern Chile

open access: yesPeople and Nature, Volume 7, Issue 8, Page 1889-1904, August 2025.
Abstract The global agrifood system faces significant threats due to rapid and interconnected social‐ecological changes, including climate change, land‐use shifts, demographic changes and emerging diseases. Small‐scale farmers are among the most vulnerable groups to these changes due to their direct dependence on their environment.

Claw growth rates in a subset of adult, indoor, domestic cats (Felis catus)

open access: yesVeterinary Dermatology, Volume 36, Issue 3, Page 362-367, June 2025.
Background – Keratinised tissues, such as nails and claws, accumulate hormones over time; the claws' hormone concentrations are being explored as potential biomarkers. Timelines for hormone deposition can be established if claw growth rates are known. Hormone concentration within cat claws has been recently evaluated, yet the growth rates of cat claws ...

ABOUT THE BEST LINEAR UNBIASED PREDICTOR (BLUP) AND ASSOCIATED RESTRICTIONS SOBRE LA CONSTRUCCIÓN DEL MEJOR PREDICTOR LINEAL INSESGADO (BLUP) Y RESTRICCIONES ASOCIADAS

open access: yesRevista Colombiana de Estadística, 2007
The mixed linear model is characterized using the classic linear model of Gauss-Markov. The multipliers of Lagrange are a tool to obtain the best lineal predictors (BLUP), we shown the results of Searle (1997), where some sums of the best linear unbiased
