Drought increase since the mid-20th century in the northern South American Altiplano revealed by a 389-year precipitation record

Autor: M. S. Morales, D. B. Crispín-DelaCruz, C. Álvarez, D. A. Christie, M. E. Ferrero, L. Andreu-Hayles, R. Villalba, A. Guerra, G. Ticse-Otarola, E. C. Rodríguez-Ramírez, R. LLocclla-Martínez, J. Sanchez-Ferrer, E. J. Requena-Rojas

Publikováno v: Climate of the Past, Vol 19, Pp 457-476 (2023)

Given the short span of instrumental precipitation records in the South American Altiplano, longer-term hydroclimatic records are needed to understand the nature of climate variability and to improve the predictability of precipitation, a key natural

Autor: L. Mereles, M. L. Castelló, P. Piris, R. Villalba, E. Coronel, S. Caballero, J. López, A. Suárez, M. D. Ortolá, C. Figueras, E. A. Gómez

Publikováno v: Biology and Life Sciences Forum, Vol 25, Iss 1, p 18 (2023)

Knowledge of the physicochemical characteristics of organic moringa leaves, such as the color, the moisture control and water activity (aw) for biological control, as its basic composition, provides valuable starting data for its improvement and qual

Mistol-Based Vegan Beverages for a Healthy Diet

Autor: R. Villalba, J. Belotto, E. Coronel, A. Suárez, S. Caballero, L. Mereles

Publikováno v: Biology and Life Sciences Forum, Vol 25, Iss 1, p 9 (2023)

The fruit of Sarcomphalus mistol (Griseb.) is from the Great American Chaco, an important wild food resource. However, its composition and potential uses are unknown to a large part of the population. In this work, two mistol and peanuts-based produc

Forest carbon sink neutralized by pervasive growth-lifespan trade-offs

Autor: R. J. W. Brienen, L. Caldwell, L. Duchesne, S. Voelker, J. Barichivich, M. Baliva, G. Ceccantini, A. Di Filippo, S. Helama, G. M. Locosselli, L. Lopez, G. Piovesan, J. Schöngart, R. Villalba, E. Gloor

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-10 (2020)

The universality of the trade-off between early growth and lifespan in trees and its implications are disputed. Analysing a global tree ring dataset and performing data-driven simulations, the authors demonstrate the pervasiveness of the trade-off an

Targeted Inhibition of Select Extracellular Signal-regulated Kinases 1 and 2 Functions Mitigates Pathological Features of Asthma in Mice

Autor: Sushrut D. Shah, Ajay P. Nayak, Pawan Sharma, Dominic R. Villalba, Sankar Addya, Weiliang Huang, Paul Shapiro, Maureen A. Kane, Deepak A. Deshpande

Publikováno v: American Journal of Respiratory Cell and Molecular Biology. 68:23-38

ERK1/2 (extracellular signal-regulated kinases 1 and 2) regulate the activity of various transcription factors that contribute to asthma pathogenesis. Although an attractive drug target, broadly inhibiting ERK1/2 is challenging because of unwanted ce

Modelling tree ring cellulose δ18O variations in two temperature-sensitive tree species from North and South America

Autor: A. Lavergne, F. Gennaretti, C. Risi, V. Daux, E. Boucher, M. M. Savard, M. Naulier, R. Villalba, C. Bégin, J. Guiot

Publikováno v: Climate of the Past, Vol 13, Pp 1515-1526 (2017)

Oxygen isotopes in tree rings (δ18OTR) are widely used to reconstruct past climates. However, the complexity of climatic and biological processes controlling isotopic fractionation is not yet fully understood. Here, we use the MAIDENiso model to
