La finalidad de estas plantaciones era bienintencionada: fijar las dunas, crear puestos de trabajo, y generar un ambiente forestal agradable. En ese marco ambiental se realizaron las plantaciones de pino.

Por ello se aconseja visitar pronto las zonas afectadas con el fin de detectar puntos donde es posible que esto ocurra, y en su caso, poder aplicar medidas para evitarlo. Estas zonas sensibles suelen estar asociadas a pendientes pronunciadas, suelos poco pedregosos, texturas arenosas, bancales abandonados, etc..

In early August, a lightning-ignited fire burned about ha of the municipalities of Llutxent, Gandia and Pinet in Valencia, Spain : the Llutxent fire [1]. The area includes a small and isolated patch cork oak Quercus suber ; Fig.

    The Pinet forest ca. The area is not the most optima for cork oak because of the climate relatively dry for the species and the soils not too acidic. Cork oak is a very good postfire resprouter from epicormic stem buds [3,4,5]. However, given that this population is in the edge of their environmental conditions, and the rainfall of the last year was below the long-term average, there were concerns about their postfire regeneration. Happily 1 month after the fire there were some oak resprouting epicormically [1], and two month after the fire, basically all individuals were resprouting Fig.

    Because some plants may die after their initial vigorous resprouting [6], we should keep monitoring the resprouting of this population, but it seems that the population is saved. The fire temporally reduced the shrublands and killed most pines of the forest, and thus it could be an opportunity for managers to increase the cork population size using local acorns. Cork oak Quercus suber in the Iberian peninsula. Light grey is the species distribution; dark grey is the data from forest inventories; crosses are small isolated populations.

One of the unifying approaches in ecology is to search for common strategies, that is, to group species sharing mechanisms and responses to environmental factors and disturbances. Plant strategies to persist in fire-prone ecosystems and the traits involved are now quite well known [1].

    However, less is known about fire strategies in animals, despite many fire-prone ecosystems harbor a very rich fauna [2]. This difference in knowledge is probably due to the intrinsic differences between plants immobile and animals mobile [2]. However, there is a demand for unifying plant an animals paradigms in order to better asses biodiversity in fire-prone ecosystems [3]. In a recent paper [4] I am providing an unifying framework by emphasizing the similarities between plants and animals in relation to the mechanisms for living in fire-prone ecosystems.

    To do so, I propose a very simple fire strategy scheme that should be valid for both plants and animals Table 1. The advantage of having a unified framework of fire strategies include: 1 we can learn how species respond to fire from a great diversity of life forms; 2 animal and plant ecologists can benefit from shared expertise in fire responses some common strategies in plants may be overlooked in animals, or vice-versa ; 3 we could better predict changes in plant-animal interactions with fire regime changes, and 4 we could better assess and generalize the effects of fire on biodiversity.

    I hope this framework would facilitate finding knowledge gaps and directing future research for gaining a better understanding of the role of fire on biodiversity. Table 1. Generalized mechanisms of species response to fire strategy , their fire dynamics and persistence scale, and the prevalence for animals and plants in fire prone ecosystems low, moderate, and high. The rhea Rhea americana has a cryptic coloration in postfire environments, when sitting in the ground, the neck cannot be differentiated from a burned stem.

    You show them by replacing fear with a sense of wonder. See also: A fire ecology lesson from the Florida scrub. In early August a wildfire ignited by a lightning burned about ha, affecting mainly the municipalities of Lutxent, Gandia and Pinet in Valencia, Spain. One month later I visited the area, and below are the main plant species that were already resprouting. There were also many seedling germination from the seedbank, but they were too small to identify. The area affected by the fire include a small marginal population of Quercus suber cork oak; el surar de Pinet that we had studied few years ago [2].

    This oak was also resprouting epicormically. Urginea maritima, 1 month Scilla autumnalis, 1 month Smilax aspera Daphne gnidium Quercus coccifera Pistacia lentiscus Globularia alypum Phillyrea angustifolia Erica scoparia Pteridium aquilinum Quercus suber Fraxinus ornus Chamaerops humils Lonicera implexa Thymus piperella.

    La finalidad de todo ser vio es reproducirse, y en el caso de las plantas esto incluye que las semillas germinen en un ambiente favorable para su crecimiento. Pero hay otras que aprovechan los espacios abiertos por incendios! Este es el caso del pino carrasco Pinus halepensis , tan abundante en nuestro territorio.

    Fire may disrupt plant-animal interactions. In antagonistic interactions, this disruption may benefit one of the interacting species; for instance, the reduction of a seed predator after fire can benefit the host plant [1]. The question is what happen in mutualistic interactions?

    Does fire disrupt mutualistic interactions generating negative consequences for the interacting species? The Mediterranean dwarf palm Chamaerops humilis is a small dioecious palm native to the coastal shrublands of the western Mediterranean Basin. It has a specialized nursery pollination system involving the weevil Derelomus chamaeropis Curculionidae. The plant resprouts quickly after fires from apical buds and produces flowers the following spring [2].

    Given the specialized nursery pollination systems, this plant is a good candidate to have their pollination disrupted by fire. In a recent study [3] we found that after fire, their pollinator the weevil , was strongly reduced, but the fruit set remained unchanged. We documented a second beetle, a sap beetle Meligethinus pallidulus , Nitidulidae , that were not affected by fire and acted as an effective pollinator in a non-nursery pollination system.

    The temporary replacement by a sap beetle at burnt sites — an effective pollinator that had gone unnoticed until now — provided postfire reproductive resilience. That is, fire does not disrupt pollination in this specialized plant-insect system. The dwarf palm Chamaerops humilis is well adapted to recurrent shrubland fires i. It resprouts quickly after fire from surviving apical buds; it has rhizomes from where new stems can emerge after disturbance I suppose this is why Humboldt mentioned this species as a social palm [2] ; and its pollination is not jeopardized by fire.
