Habitat dynamics of flagship species for conservation prioritization in southern Europe

open access: yesConservation Biology, Volume 39, Issue 4, August 2025.
Abstract Biodiversity loss is accelerating due to human actions, and decision‐making for conservation needs to be streamlined. Ex situ biodiversity modeling and monitoring based on satellite time‐series data could be an affordable and cost‐efficient tool for improving the prioritization of conservation areas.

Intraspecific variation and detectability of iridescence in the dorsal coloration of a wall lizard

open access: yesJournal of Zoology, Volume 326, Issue 3, Page 239-255, July 2025.
Wall lizards (genus Podarcis) show substantial intraspecific colour variation and iridescence, which may interact and affect overall colour appearance. Here, we set out to study iridescence in Podarcis liolepis in two localities in which lizards are known to differ in dorsal coloration. Our results show that P.

Analysis of the High-Frequency Content in Human QRS Complexes by the Continuous Wavelet Transform: An Automatized Analysis for the Prediction of Sudden Cardiac Death

open access: yesSensors, 2018
Background: Fragmentation and delayed potentials in the QRS signal of patients have been postulated as risk markers for Sudden Cardiac Death (SCD). The analysis of the high-frequency spectral content may be useful for quantification.

Towards a global understanding of tree mortality

open access: yesNew Phytologist, Volume 245, Issue 6, Page 2377-2392, March 2025.
Summary Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground‐based long‐term forest monitoring with large‐scale remote sensing.

Physiological thermal niches, elevational ranges and thermal stress in dendrobatid frogs: An integrated approach

open access: yesJournal of Biogeography, Volume 51, Issue 10, Page 1880-1893, October 2024.
Abstract Aim We investigated the relationship between thermal physiology, elevational distribution and thermal stress among nine closely related dendrobatid frogs during their aquatic stage by employing an integrated approach, combining thermal physiology, environmental temperature modelling and predictive assessments of current and future exposure to ...

Cuestiones abiertas en la modelización del riesgo operacional en los acuerdos de Basilea: El umbral de pérdidas y la distribución de severidad

open access: yesRevista Galega de Economía, 2014
El cálculo de los requerimientos de capital por riesgo operacional en los Acuerdos de Basilea es un tema aún abierto en la práctica bancaria. En este artículo, a partir de una base de datos de pérdidas de una caja de ahorros española, se analiza el impacto sobre el capital económico de dos elementos considerados críticos en la modelización del
