Las diferencias observadas entre especies fueron altamente significativas y sugieren que las particularidades ecológicas de cada una, especialmente en relación con el hábito y la amplitud de nicho, determinan la variación del SLA y el LDMC. Por otro lado, aunque se observaron diferencias ligeramente significativas entre poblaciones de montaña y de colina, la baja potencia del análisis hizo que los resultados no fueran concluyentes.

Therefore we examined the aerial and terrestrial adventitious roots of Epipremnum aureum for the endophytic association and the soils for GAM spores. The aerial roots of E. aureum were free from fungal structures, whereas the terrestrial roots were colonized by GAM, fine root endophyte (FRE), and DSE fungi. The major portion of the terrestrial roots was colonized by FRE fungi followed by GAM and DSE fungi. The colonization pattern was a complex of Arum-Paris and intermediate types. Spores of Acaulospora, Funneliformis, Rhizophagus, Rhizophagus and Sclerocystis were isolated from the root zone soils. The results show that E. aureum can establish symbiosis with a wide range of endophytic fungi and FRE symbiosis is reported for the first time in aroids.","PeriodicalId":39509,"journal":{"name":"Botanica Complutensis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44423931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plates have been cultured in chambers with nutritive agar at 25ºC and 12 hours photoperiod. The germination was registered every three days, and the main vegetative and reproductive development was checked throughout the observational period. The germination rate reached a maximum of 58%. The spore germination followed a Vittaria pattern meanwhile prothallial development followed an Adiantum type.

In this work, we have studied this taxon at both the morphological and the anatomical level, as well as its ecology and geographical distribution. We found differences between C. opaca s.s. and B. deplanchei in the morphology of the sterile and fertile fronds, in several morphoanatomical features such as trichome shape, length, and distribution, and length and/or shape of different structures of sporangia and spores. The distribution of both taxa was also different, but they are sympatric at some localities. The differences identified in this study support the recognition of both taxa, and the combination of Cranfillia deplanchei (Baker) Vázquez Ferreira & Gabriel y Galán, which we propose here.

Habitat together with morphology of megaspores were used as diagnostic features.

Intermediate individuals have been found in the Western Central System. The differentiation within the I. velata group appears to be the result of gradual genetic divergence after isolation. Palaeobotanical data confirm the presence of I. velata subsp. asturicense in Late Glacial lake sediments in northwestern Spain. Cluster classification of the soft-water vegetation with Isoetes velata subsp. asturicense revealed two main groups in the Spanish Central System. A single association, the Sparganio angustifolii-Callitrichetum fontqueri which includes Iberian Atlantic stands of Sparganium angustifolium and Isoetes velata subsp. asturicense, is here recognized.
