“…Las estaciones de crecimiento más largas y más cálidas aumentan el secuestro de carbono (White et al, 2009), pero también aumentan la evapotranspiración y el estrés por la sequía (zhang et al, 2009) y pueden aumentar la incidencia de incendios forestales (Westerling et al, 2006). A nivel especifico, el adelanto de la estación de crecimiento del pinsapo ha sido detectado por otros autores trabajando con técnicas de fenomorfología (Pérez-Latorre & Cabezudo, 2012). Se ha observado que el pinsapo es especialmente sensible a la falta de agua durante la primavera (Linares et al, 2011b).…”

“…Es un árbol de porte piramidal que puede alcanzar hasta los 30 m de altura, con un tronco de hasta 1 m de diámetro, si bien en condiciones naturales no suele sobrepasar los 20 m (López, 2007). Florece entre abril y mayo y forma las piñas entre junio y octubre, un periodo relativamente largo, quizás como respuesta a la sequía estival, diseminando las semillas a continuación (Pérez-Latorre & Cabezudo, 2012). Desde el punto de vista ecofisiológico, las principales diferencias con respecto al otro abeto que habita en la península Ibérica, Abies alba, son su mejor adaptación a la sequía y su menor tolerancia al frío (Peguero-Pina et al, 2011;Sancho-Knapik et al, 2014).…”

El pinsapo es una reliquia botánica del Terciario que persiste en un singular ecosistema de montaña. Es una especie endémica e insólita en el paisaje andaluz, por lo que se halla muy protegida y es objeto de una estrategia de conservación activa que pretende mitigar los efectos negativos del cambio global. En este artículo utilizamos 180 imágenes del sensor MODIS para desarrollar un análisis interanual y de tendencia estacional del NDVI promedio mensual, desde 2002 hasta 2016, de las superficies cubiertas por pinsapos. De acuerdo con los resultados obtenidos, se ha producido un incremento generalizado del NDVI en las masas forestales con presencia del pinsapo. La tendencia fue significativa en casi todos los tipos de formaciones y grados de cobertura. Esto sugiere una regeneración de los pinsapares en el marco de la estrategia de conservación activa. Sin embargo, detectamos un adelanto del Green up, hecho que podría estar relacionado con el calentamiento global.

Coping with low light under high atmospheric dryness: shade acclimation in a Mediterranean conifer (Abies pinsapo Boiss.)

et al. 2014

Plant species living in the understory increase carbon (C) allocation toward leaf production for maximizing light capture at the expense of roots and stems, with negative consequences for the whole-plant hydraulic conductance. Moreover, under some conditions, the high atmospheric evaporative demand occurring in Mediterranean areas may be not well buffered by the canopy, which might be the case for relict conifer Abies pinsapo Boiss. growing in the forest understory. We hypothesized that acclimation to combined understory shade and high atmospheric dryness can be achieved through the adjustment of water losses to cope with the restriction in water transport. The results reveal high structural plasticity in A. pinsapo that allows light harvesting of this species to maximize light capture in the forest understory, and maintain a positive C balance under low light conditions. However, growth in the understory resulted in reduced leaf-specific conductivity, up to approximately four to five times, implying decreased plant capacity to supply water to the leaves. In order to cope with the high atmospheric evaporative demand in the understory, there is an adjustment of the stomatal conductance to the hydraulic conductivity by means of a reduction in the stomatal density in understory individuals, which is due to the almost complete lack of stomata in the adaxial side of the needles. To the extent of our knowledge, such a drastic phenotypic response found in a conifer when growing under shaded conditions had not been previously reported.

“…The high diversity of growth forms in Mediterranean ecosystems is a demonstration of this, although specific patterns showing a certain synchrony with climate have been detected (Kummerow 1983, Orshan 1989, Montserrat-Martí et al 2004). In the Mediterranean Basin, a great deal of phenological studies in the Iberian Peninsula has established a general time of occurrence of the different phenophases in flora (Castro-Díez and Montserrat-Martí 1998, Navarro and Cabezudo 1998, Monserrat-Martí and Pérez-Rontomé 2002, Pérez-Latorre and Cabezudo 2002, Palacio 2006, Pérez-Latorre et al 2007, 2009, Milla et al 2010, Pérez-Latorre and Cabezudo 2012.…”

“…These characteristics suggest that serpentine habitats are very selective and drive the way in which taxa evolve (Brooks , Roberts and Proctor , Kruckeberg ). In fact, only a small part of the taxa of regional floras is adapted to growing under these conditions, some showing certain adaptations at a morphological‐functional level such as serpentinomorphoses (Pichi Sermolli , Jenny ) or having more ‘stress‐tolerant’ traits than non‐serpentine communities (Fernandez‐Going et al , Adamidis et al ). In some cases, it has been found that isolation of the population can lead to changes in the time of flowering (Macnair and Gardner ), which may be genetically associated with early reproduction under drought conditions or represent a plastic phenotypic response to a decrease of soil water availability (Hughes et al 2001, Brady et al , Wright et al ).…”

Phenological phases have been studied in Mediterranean serpentine shrubland vegetation in the south of the Iberian Peninsula to obtain a phenological characterization of the serpentine flora and to make a comparison between endemic serpentine and non‐serpentine plants in different years and altitudes. For this purpose, data were taken in the serpentine ecosystem of Sierra Bermeja (Andalusia, Spain) establishing two plots on two altitudinal bioclimatic belts and during two different years. A total of 28 persistent taxa were studied, including both serpentinophytes, their magnesicolous allies and non‐serpentinophytes, to detect possible differences between serpentine and non‐endemic taxa. Phenological calendars and phenological patterns (phenophasic indexes) were obtained. The species showed phenophasic patterns similar to those of other studied Mediterranean flora: a phenological pause coinciding with summer and most species behaving as summer semi‐deciduous with seasonal dimorphism. There were no statistically significant differences in phenology and in phenological indexes due to altitude or serpentine affinity. The best represented active phenophasic period of the species was 9–11 months of activity although showing the summer phenological pause. Species with low index of reproductive/vegetative activity of the species predominated, employing more time/resources for vegetative functions, and with synchronous phenophases, where flowering and growth coincide. The phenophasic period of serpentinophytes and magnesicolous taxa pointed to a certain delay in the period of flowering with respect to the group of non‐serpentinophytes, a result which could have important implications for reproduction.
