Fireline production rate of handcrews in wildfires of the Spanish Mediterranean region
(CSIRO, 2023)Background. Handcrews dig handlines to bare mineral soil for fire containment. Increasing the amount of firefighting resources is insufficient to mitigate wildfire damage or decrease the number of large fires. Aims. This ... -
Fitotoxicidad del fosfonato en brinzales de encina Quercus ilex L. subsp. ballota (Desf.) Samp.
(Ministerio de Medio Ambiente, Medio Rural y Marino, 2007)El fosfonato es un fertilizante foliar que ha sido utilizado con éxito en el control de P. cinnamomi en varias especies forestales. Aunque se considera que los fosfonatos tienen un bajo nivel de toxicidad, se han observado ... -
Forest plantations in Manabí (Ecuador): assessment of fragmentation and connectivity to support dry tropical forests conservation
(MDPI, 2023)In many tropical regions, national forests plantation programs have been promoted. Those plantations frequently contribute to habitat changes. However, the associated effects of forest plantations on habitat fragmentation ... -
Fragmentation and Connectivity in dehesa Ecosystems Associated with Cerambyx spp. Dispersion and Control: A Graph-Theory Approach
(MDPI, 2024)Xylophagous insects play a crucial role in forest ecosystems, contributing to population dynamics. The “Cerambyx complex” (CC) constitutes an emerging pest in Mediterranean oak woodlands. We studied the fragmentation and ... -
Fuel Modelling Characterisation Using Low-Density LiDAR in the Mediterranean: An Application to a Natural Protected Area
(MDPI, 2021)Fuel structure and characteristics are important to better understand and predict wildfire behaviour. The aim of the present study was to develop a methodology for characterising fuel models using low-density and free LiDAR ... -
Getting Ahead of the Wildfire Problem: Quantifying and Mapping Management Challenges and Opportunities
(MDPI, 2016)Wildfire is a global phenomenon that plays a vital role in regulating and maintaining many natural and human-influenced ecosystems but that also poses considerable risks to human populations and infrastructure. Fire ... -
Global ecosystem thresholds driven by aridity
(American Association for the Advancement of Science, 2020)Aridity, increasing worldwide due to climate change, affects the structure and functioning of dryland ecosystems. Whether aridification leads to gradual (vs. abrupt) and systemic (vs. specific) ecosystem changes is largely ... -
Global monitoring of soil multifunctionality in drylands using satellite imagery and field data
(Zoological Society of London, 2023)Models derived from satellite image data are needed to monitor the status of terrestrial ecosystems across large spatial scales. However, a remote sensing-based approach to quantify soil multifunctionality at the global ... -
Growth and physiological sapling responses of eleven Quercus ilex ecotypes under identical environmental conditions
(Elsevier, 2018)Studies with holm oak indicate that genetic variation may result in substantial differences in drought tolerance among its ecotypes. However, few trials have studied this variation under common environmental conditions. ... -

Humanismo y transdisciplinariedad en la era de la enseñanza virtual
(Universidad de Córdoba, Vicerrectorado de Innovación y Calidad Docente, 2005)Recent social changes have led to the information era involving dramatic changes in the education. In this sense, internet is more than a learning tool in the e-society. Teachers have to adapt to the new paradigm to assume ... -
Hyperspectral and multispectral satellite sensors for mapping chlorophyll content in a Mediterranean Pinus sylvestris L. plantation
(Science Direct, 2014)A new generation of narrow-band hyperspectral remote sensing data offers an alternative to broad-band multispectral data for the estimation of vegetation chlorophyll content. This paper examines the potential of some of ... -
Improvement of Remote Sensing-Based Assessment of Defoliation of Pinus spp. Caused by Thaumetopoea pityocampa Denis and Schiffermüller and Related Environmental Drivers in Southeastern Spain
(MDPI, 2019)This study used Landsat temporal series to describe defoliation levels due to the Pine Processionary Moth (PPM) in Pinus forests of southeastern Andalusia (Spain), utilizing Google Earth Engine. A combination of remotely ... -
Improvements of Fire Fuels Attributes Maps by Integrating Field Inventories, Low Density ALS, and Satellite Data in Complex Mediterranean Forests
(MDPI, 2023)One of the most determining factors in forest fire behaviour is to characterize forest fuel attributes. We investigated a complex Mediterranean forest type—mountainous Abies pinsapo–Pinus–Quercus–Juniperus with distinct ... -
In situ measurement of Scots pine needle PRI
(BMC, 2017)Background: The Photochemical Reflectance Index (PRI) calculated from narrow-band spectral reflectance data is a vegetation index which is increasingly used as an indicator of photosynthetic activity. The leaf-level link ... -
Incidencia de la podredumbre radical causada por "Phytophthora cinnamomi" en masas de "Quercus" en Andalucía
(Ministerio de Agricultura, Pesca y Alimentación: Centro de Publicaciones Agrarias, Pesqueras y Alimentarias, 2003)Entre los factores bióticos implicados en la Seca de los Quercus destaca la podredumbre radical causada por Phytophthora cinnamomi. En este trabajo se ha estudiado la incidencia de P. cinnamomi en masas de Quercus afectadas ... -
Influencia del cultivo de Lupinus luteus L. en la densidad de inóculo de Phytophthora cinnamomi en suelos de dehesa
(Sociedad Española para el Estudio de los Pastos, 2009)Phytophthora cinnamomi es un patógeno que causa podredumbre radical en el arbolado de la dehesa y también en Lupinus luteus, cultivo frecuente en dehesas de Andalucía occidental. En dehesas que mostraban distintas situaciones ... -

Integración del patrimonio natural y redes de infraestructura verde como mejora de los bienes públicos del olivar con orientación turístico-recreativa
(UCOPress, 2022)El paisaje del olivar tradicional viene sufriendo distintos riesgos agravados por la actual crisis del sector, su simplificación, abandono, o arranque, y sus efectos en la población local y en su valor natural hacen necesario ... -
Integrating dendrochronological and LiDAR data to improve management of Pinus canariensis forests under different thinning and climatic scenarios
(MDPI, 2024)Thinning focused on achieving growth and diameter management objectives has typically led to stands with reduced climate sensitivity compared to unthinned stands. We integrated dendrochronological with Airborne Laser Scanner ...
