“…Thus, nutrient deficiencies in trees are easily observed in pine needles, which increases the interest in nutrient cycling studies in these forests. Third, mature P. canariensis trees resist severe forest fires (Climent et al, 2004), burned stands being very comparable in terms of tree structure and age. The altitude of the study area is between 1200 and 1500 m, with mean annual rainfall of 600 mm and mean annual temperature of 16 • C (Climent et al, 2004).…”

Keywords:forest wildfire / ionic exchange membrane / SADIE / soil nutrient availability / spatial heterogeneity Abstract • Soil resources are heterogeneously distributed in terrestrial plant communities. This heterogeneity is important because it determines the availability of local soil resources. A forest fire may change the spatial distribution of soil nutrients, affecting nutrition and survival of colonizing plants. However, specific information on the effects of ecosystem disturbance on the spatial distribution of soil resources is scarce.• We hypothesized that, on a short-term basis, wildfire would change the spatial patterns of soil N and P availability. To test this hypothesis, we selected two Pinus canariensis forests burned in 2005 and 2000, respectively, and a third forest that was unburned since at least 1990 (unburned). We incubated ionic exchange membranes (IEMs) in replicated plots to estimate soil N and P availability and characterized the spatial pattern using SADIE (Spatial Analysis by Distance Indices).• Mineral N, NO 3 -N and PO 4 -P availability, and aggregation and cluster indices for all nutrients were higher in the 2005 wildfire plots than in the 2000 wildfire and unburned plots.• Our results suggest that surviving plants or new individuals becoming established in a burned area would find higher soil resources, but also higher small-scale heterogeneity in nutrients, which may have a major impact on the performance of individual plants and on the forest structure and dynamics.Mots-clés : feu de forêt / membrane d'échange ionique / SADIE / disponibilité des éléments nutritifs du sol / hétérogénéité spatiale Résumé -Un incendie modifie la configuration spatiale de la disponibilité des éléments nutritifs dans les sols de forêts de Pinus canariensis.• Les ressources du sol sont distribuées de manière hétérogène dans les communautés végétales terrestres.

“…This ability is especially useful in volcanic territories allowing the rapid colonisation of new areas originating from lava flows, which is indeed the case for the Canary Islands. Accordingly, Canarian pine stands described in some works as having high tree density but low regeneration might actually be young populations replacing old ones damaged by past disturbances (Höllermann 2000;Climent et al 2004).…”

“…It is well adapted to forest fires, although it is not clear whether its regeneration depends on the occurrence of forest fires. This species combines serotinous and non-serotinous cones, moreover, adults have an extraordinary sprouting capacity after fire, resulting in a mixture of stand resilience and individual resistance strategies (Climent et al 2004). The importance of serotinous cones in this species is lower compared with other Mediterranean obligate seeder pines adapted to fire-prone environments, like P. halepensis (less than 40 % vs. between 50 and 100 % of serotinous cones in P. canariensis and P. halepensis, respectively) (Climent et al 2004;Nathan et al 1999).…”

“…Abundant seed rain has also been detected in P. canariensis in the absence of fires (Garcia-del-Rey et al 2011), but the dynamics of seed rain, regardless of the cone type involved, has never been studied. Previous studies of Canarian pine forests have focused on post-fire regeneration and the influence of stand conditions at early stages (Höllermann 2000;Arévalo et al 2001;Peters et al 2001;Climent et al 2004;Otto et al 2010); however, long-term studies of successive regeneration have not been carried out.…”

In land plants, heteroblasty broadly refers to a drastic change in morphology during growth through ontogeny. Juniperus flaccida and Pinus cembroides are conifers of independent lineages known to exhibit leaf heteroblasty between the juvenile and adult life stage of development. Juvenile leaves of P. cembroides develop spirally on the main stem and appear decurrent, flattened, and needle‐like; whereas adult photosynthetic leaves are triangular or semi‐circular needle‐like, and grow in whorls on secondary or tertiary compact dwarf shoots. By comparison, J. flaccida juvenile leaves are decurrent and needle‐like, and adult leaves are compact, short, and scale‐like. Comparative analyses were performed to evaluate differences in anatomy and gene expression patterns between developmental phases in both species. RNA from 12 samples was sequenced and analyzed with available software. They were assembled de novo from the RNA‐Seq reads. Following assembly, 63,741 high‐quality transcripts were functionally annotated in P. cembroides and 69,448 in J. flaccida. Evaluation of the orthologous groups yielded 4140 shared gene families among the four references (adult and juvenile from each species). Activities related to cell division and development were more abundant in juveniles than adults in P. cembroides, and more abundant in adults than juveniles in J. flaccida. Overall, there were 509 up‐regulated and 81 down‐regulated genes in the juvenile condition of P. cembroides and 14 up‐regulated and 22 down‐regulated genes in J. flaccida. Gene interaction network analysis showed evidence of co‐expression and co‐localization of up‐regulated genes involved in cell wall and cuticle formation, development, and phenylpropanoid pathway, in juvenile P. cembroides leaves. Whereas in J. flaccida, differential expression and gene interaction patterns were detected in genes involved in photosynthesis and chloroplast biogenesis. Although J. flaccida and P. cembroides both exhibit leaf heteroblastic development, little overlap was detected, and unique genes and pathways were highlighted in this study.
