“…in Ananas, Aechnea, Bilbergia and Nidularium (Grippa et aI., 2007;Wang and Qiu, 2006). This may be due to a difference in their habitat (terrestrial versus epiphytic), and is consistent with the presence of AM in the rest of the terrestrial species of the Pitcairnoidea, The absence, in our study, of AM in Bromeliodeae and the presence of DSE in Tillansioidea agree with the findings of others and may be associated with the evolution of a capacity to conquer the canopy and exist as epiphyte (Maffia et aI., 1993;Michelsen, 1993;Nadarajah and Nawawi, 1993).…”

Most plant roots are associated with glomalean fungi forming arbuscular rnycorrhizas (AM) and a wide range are also colonized by ascomycetous dark septate endophytes (DSE). Bromeliaceae species can be epiphytic, rupicolous or terrestrial but their mycorrhizal status is poorly studied. We examined the AM and DSE status of 5 epiphytic and 4 terrestrial Bromeliaceae from an arid area of Central Argentina. The terrestrial species were either dually associated (AM and DSE) or non-associated whereas the epiphytes were only DSE colonized. Terrestrial Brorneliaceae that formed AM-DSE associations were likely responding to the arid conditions of the area and the availability of AM fungal (AMF) spores in the soil. The terrestrial Bromelia ubaniana was not colonized either by AMF or DSE. This could reflect its root morphology and high number of root hairs. DSE are endosymbiotic in the stressful ecosystems experienced by canopy epiphytes in the studied environment. The different fungal associations are discussed in relation to the three Bromeliaceae subfamiles and we suggest that environmental features determine the type of association formed by species in this plant family.

Arbuscular mycorrhizal, Mucoromycotina and dark septate fungi in ferns and lycophytes with distribution in Mexico: a global review. Ferns and lycophytes are a group of vascular plants of interest to understand the evolution of mycorrhizal interactions; their preservation is of relevance for their multiple ecological relations. The record of different taxonomic groups of fungi associated with ferns and lycophytes is fragmentary, and the criteria for it identification is inconsistent, which hinders the understanding and determination of mycorrhizal status. The aim of this study was to determine the percentage of the species of ferns and lycophytes with distribution in Mexico, and with information of fungal interactions. A checklist of the presence of arbuscular mycorrhizal fungi (AMF), Mucoromycotina and dark septate fungi (DSF) associated with ferns and lycophytes was integrated through an exhaustive global literature search. In this study, mycorrhizal species was considered by the presence of arbuscules to differentiate with hyphal, vesicular and coils colonization. The study gathered a checklist of mycorrhizal occurrences of 27 families, 61 genus and 137 species of ferns and lycophytes, which covers 13.4 % of the species, 91 % of the genus and 77 % of the families distributed in Mexico. The 78.1 % of the species showed colonization, 56.2 % by AMF, 29.9 % by DSF and 0.72 % by Mucoromycotina fungi. From the total of the species, the higher presences of colonization were in terrestrial, epiphytic, saxicolous, and aquatic plants with 76.6 %, 33.3 %, 20 %, and 6.3 %, respectively. The families of ferns and lycophytes with the higher number of species colonized were Pteridaceae, Polypodiaceae, Aspleniaceae and Dryopteridaceae. The present study showed the widespread associations of AMF and DSF in ferns and lycophytes of Mexico. It is urgently needed to include ferns and lycophytes in studies focused on endomycorhizal interactions, since only 28 species (28 %) were studied in Mexican ecosystems. The majority of studies were focused on sporophytic face (80 %). Nonetheless, to understand the role that plays the mycorrhiza in the establishment of ferns and lycophytes, it is necessary to include the gametophytic face in ecological, molecular and physiological experimental studies. This information is important to implement conservation strategies, because a considerable number of ferns and lycophytes species, depend on these mycorrhizal associations for their growth and survival.

“…There are no previous reports on the mycorrhizal status of epiphytic plant species in semiarid Mediterranean conditions, since the only studies concerning AM symbiosis in epiphytic plants have been conducted in tropical environments. Early studies suggested that arbuscular mycorrhizas generally are absent or rare in tropical epiphytes (6,20,21). However, later reports found abundant mycorrhizal 7) showing a significant mycorrhizal presence in epiphytic life forms from tropical forests.…”

“…Some epiphytes have evolved adaptations that provide efficient access to and retention of nutrients, such as litter-trapping leaf arrangements, slow growth rates, absorbent trichomes, and mycorrhizas (3,4). The results of previous studies suggest that many plant species that are commonly mycorrhizal when they grow terrestrially are inconsistently mycorrhizal when they grow epiphytically (5,6). However, Rains et al (4) found abundant mycorrhizal structures on epiphytic roots indicating a significant mycorrhizal presence (arbuscular and ericoid mycorrhizas) in the canopy of a lower montane cloud forest in Costa Rica.…”

bIn semiarid Mediterranean ecosystems, epiphytic plant species are practically absent, and only some species of palm trees can support epiphytes growing in their lower crown area, such as Phoenix dactylifera L. (date palm). In this study, we focused on Sonchus tenerrimus L. plants growing as facultative epiphytes in P. dactylifera and its terrestrial forms growing in adjacent soils. Our aim was to determine the possible presence of arbuscular mycorrhizal fungi (AMF) in these peculiar habitats and to relate AMF communities with climatic variations. We investigated the AMF community composition of epiphytic and terrestrial S. tenerrimus plants along a temperature and precipitation gradient across 12 localities. Epiphytic roots were colonized by AMF, as determined by microscopic observation; all of the epiphytic and terrestrial samples analyzed showed AMF sequences from taxa belonging to the phylum Glomeromycota, which were grouped in 30 AMF operational taxonomic units. The AMF community composition was clearly different between epiphytic and terrestrial root samples, and this could be attributable to dispersal constraints and/or the contrasting environmental and ecophysiological conditions prevailing in each habitat. Across sites, the richness and diversity of terrestrial AMF communities was positively correlated with rainfall amount during the most recent growing season. In contrast, there was no significant correlation between climate variables and AMF richness and diversity for epiphytic AMF communities, which suggests that the composition of AMF communities in epiphytic habitats appears to be largely determined by the availability and dispersion of fungal propagules from adjacent terrestrial habitats. E piphytism is a characteristic life form of humid and perhumid tropical forest, especially those at middle and higher elevations denominated montane cloud forest. In Mediterranean ecosystems, epiphytic vegetation is restricted to some mesic habitats in temperate regions where ferns, lichens, and bryophytes are common as epiphytes on the trunks of living trees. In semiarid Mediterranean ecosystems, characterized by low irregular annual rainfall and high temperatures (mild winter temperatures and hot summer), epiphytic plant species are practically absent. Actually, under these semiarid environmental conditions, only some species of palm trees can support epiphytes growing in their lower crown area, such as Phoenix canariensis (1), which is restricted to gardens, or Phoenix dactylifera (date palm), which is widely cultivated and frequently naturalized (2). In date palms the armpits of cut leafs form a good mechanical support place for epiphyte establishment and growth and also constitute an enabling environment for the accumulation of water and organic matter. Although several plant species can eventually be found as facultative epiphytes (epiphytes that can inhabit the canopy or ground interchangeably (3), the most common species and almost always present growing on date palm trunks is Sonchus tenerrimus L., a wi...
