- Different taxonomic and functional indices complement the understanding of herb-layer community assembly patterns in a southern-limit temperate forest(2022) Ibañez-Gaston, R. (Ricardo); Valerio-Galán, M. (Mercedes); Gazol, A. (Antonio); Puy, J. (Javier)The efficient conservation of vulnerable ecosystems in the face of global change requires a complete understanding of how plant communities respond to various environmental factors. We aim to demonstrate that a combined use of different approaches, traits, and indices representing each of the taxonomic and functional characteristics of plant communities will give complementary information on the factors driving vegetation assembly patterns. We analyzed variation across an environmental gradient in taxonomic and functional composition, richness, and diversity of the herb-layer of a temperate beech-oak forest that was located in northern Spain. We measured species cover and four functional traits: leaf dry matter content (LDMC), specific leaf area (SLA), leaf size, and plant height. We found that light is the most limiting resource influencing herb-layer vegetation. Taxonomic changes in richness are followed by equivalent functional changes in the diversity of leaf size but by opposite responses in the richness of SLA. Each functional index is related to different environmental factors even within a single trait (particularly for LDMC and leaf size). To conclude, each characteristic of a plant community is influenced by different and even contrasting factors or processes. Combining different approaches, traits, and indices simultaneously will help us understand how plant communities work.

(Begoña)Analysing temporal patterns in plant communities is extremely important to quantify the extent and the consequences of ecological changes, especially considering the current biodiversity crisis. Long-term data collected through the regular sampling of permanent plots represent the most accurate resource to study ecological succession, analyse the stability of a community over time and understand the mechanisms driving vegetation change. We hereby present the LOng-Term Vegetation Sampling (LOTVS) initiative, a global collection of vegetation time-series derived from the regular monitoring of plant species in permanent plots. With 79 data sets from five continents and 7,789 vegetation time-series monitored for at least 6 years and mostly on an annual basis, LOTVS possibly represents the largest collection of temporally fine-grained vegetation time-series derived from permanent plots and made accessible to the research community. As such, it has an outstanding potential to support innovative research in the fields of vegetation science, plant ecology and temporal ecology.

- Estudio de la Flora Vascular de Ilundáin (Navarra).(Servicio de Publicaciones de la Universidad de Navarra, 2002) Ibañez-Gaston, R. (Ricardo); Azqueta, A. (Amaya)En este trabajo hemos realizado un estudio de la Flora Vascular presente en Ilundáin (Navarra) en una superficie aproximada de 1.35 km2. Para ello se han recolectado los ejemplares presentes en la zona durante un periodo de tres años (de 1998 a 2001) mediante la realización de herborizaciones de los distintos ambientes, diferenciados por la vegetación dominante de cada uno (robledal, hayedo, pinar, matorral,...) y en las distintas estaciones del año. Así se han recolectado 730 ejemplares pertenecientes a 294 taxones diferentes. Se ha creado un Catálogo Florístico de la zona bajo estudio donde cada taxon está acompañado por información referente a la nomenclatura (sinónimos y nombres vulgares), información biogeográfica (tipo corológico) e información ecológicofuncional (hábitats o ambientes en los que aparece, especies acompañantes, fenología, tipo biológico,...) así como todas las citas tomadas de cada uno de ellos.
- Forest growth responses to drought at short- and long-term scales in Spain: squeezing the stress memory from tree rings(2018) Ibañez-Gaston, R. (Ricardo); Granda, E. (Elena); Sanchez-Miranda, A. (Angela); Sangüesa-Barreda, G. (Gabriel); Camarero, J.J. (Julio J.); Cantero-Fariña, A. (Alejandro); Gazol, A. (Antonio); Sanchez-Salguero, R. (Raúl); Serra-Maluquer, X. (Xavier)Drought-triggered declines in forest productivity and associated die-off events have increased considerably due to climate warming in the last decades. There is an increasing interest in quantifying the resilience capacity of forests against climate warming and drought to uncover how different stands and tree species will resist and recover after more frequent and intense droughts. Trees form annual growth rings that represent an accurate record of how forest growth responded to past droughts. Here we use dendrochronology to quantify the radial growth of different forests subjected to contrasting climatic conditions in Spain during the last half century. Particularly, we considered four climatically contrasting areas where dominant forests showed clear signs of drought-induced dieback. Studied forests included wet sites dominated by silver fir (Abies alba) in the Pyrenees and beech (Fagus sylvatica) stands in northern Spain, and drought-prone sites dominated by Scots pine (Pinus sylvestris) in eastern Spain and black pine (Pinus nigra) in the semi-arid south-eastern Spain. We quantified the growth reduction caused by different droughts and assessed the short-and long-term resilience capacity of declining vs. non-declining trees in each forest. In all cases, drought induced a marked growth reduction regardless tree vigor. However, the capacity to recover after drought (resilience) at short- and long-term scales varied greatly between declining and non-declining individuals. ..

- Colonización espontánea de taludes de desmonte sobre margas en Navarra: establecimiento y fuente de diásporas.(Servicio de Publicaciones de la Universidad de Navarra, 2005) Ibañez-Gaston, R. (Ricardo); Etxeberria, M. (M.)Tras la hidrosiembra de taludes de desmonte sobre margas en localidades navarras con clima submediterráneo se implanta una cubierta vegetal de especies hidrosembradas que experimenta una rápida regresión, tal y como hemos observado en estudios previos. A pesar de ello, algunas especies autóctonas son capaces de colonizar estas superficies. Describimos la capacidad de colonización de estas últimas especies, cuyas diásporas proceden de la lluvia de semillas, para determinar si también les afecta la regresión observada en las especies hidrosembradas. También estudiamos su distribución espacial para determinar la fuente de diásporas. A pesar de la gran dificultad para colonizar los desmontes, las especies autóctonas no siguen el modelo regresivo que presentan las especies hidrosembradas en desmontes de similares características en Navarra. Por otro lado, la mayoría de las especies disminuyen su abundancia al aumentar la distancia a la zona superior del talud, donde se encuentra la vegetación que actúa como principal fuente de diásporas.
