- PublicationOpen AccessZonación briofítica de un talud de margas calcáreas en el río Ges (Girona)(Universidad de Murcia, Servicio de Publicaciones, 1984) Sanz i Magrané, M.M.; Facultad de BiologíaThis communnication synthesizes the bryophytic vegetation observed on subvertical banks by streams near VidrA, Ripolles, (Girona, 31TDG46). Fig. 1. The results reflect an apparent vertical distribution of species in response to variation of moisture and substratum.
- PublicationOpen AccessEl orden racomitrietalia heterostichi philippi 1956 en la Península Ibérica. Nota preliminar(Universidad de Murcia, Servicio de Publicaciones, 1984) Zafra, M.L.; Varo, J.; Facultad de BiologíaBriophitic communities belonging to Grimmio-Racomitrion heterostichi Marstaller 1982 and Racomitrion lanuginosi (Gams 1927) Preis 1937 are dealt with. Associations described in the european literature are recorded. Some other communities will be published after completing their study.
- PublicationOpen AccessEsporas de briófitos I(Universidad de Murcia, Servicio de Publicaciones, 1984) Mateu, Isabel; Puche, Felisa; Facultad de BiologíaThis is the first one of a serie of papers which objetive is to characterize bryophyte spore of more important and representative taxa of the Briological lberican Flora. Some taxa of genus Grimmia Hedw. and Orthotrichum Hedw. are included at this paper: Grimmia decipiens (K.F. Schultz.) Lindb., G. laevigata (Brid.) Brid., G. orbicularis Bruch. ex Wils., G. ovalis (Hedw.) Sm., G. pulvinata (Hedw.) Sm. var. africana (Hedw.) Hook., G. trichophylla Grev.,Orthotrichum affine Brid., O. anomalum Hedw., O. cupulatum Brid., O. diaphanum Brid., 0. pallens Bruch. ex Brid., 0. pumilum Sw., O. rupestre Schwaegr. var. franzonianum (De Not.) Vent. y O. striatum Hedw. For each one the spore dimensions are taken with optical microscope observations and are studied its shape and ornamentation with S.E.M.; size and ornamentation differences are signed.
- PublicationOpen AccessEstudio del ciclo reproductivo de algunas especies de musgos(Murcia : Universidad de Murcia, Servicio de Publicaciones, 1984) Lloret, F.; Pérez, R.; Facultad de BiologíaThe reproductive cycle of the mosses Polytrichum formosum Hedw., Bartramia pomiformis Hedw., Grimmia laevigata (Brid.) Brid. and Hedwigia ciliata (Hedw.) P. Beauv. has been investigated by scoring specimens from Montseny Mountains (Barcelona. Spain) (UTM: DG 46 26). Gametangial formation, fertilization, growth of the sporophytes and spore dispersa1 are correlated with seasonal variation of the environmental factors.
- PublicationOpen AccessEstudio del contenido de metales pesados en briófitos del área metropolitana de Barcelona(Universidad de Murcia, Servicio de Publicaciones, 1984) Perez i Obiol, Ramon; Facultad de BiologíaHighways with high intensity of traffic and other significant places of the Metropolitan Area of Barcelona were studied. We have sampled several moss species testing them by spectrophotometer of atomic absorption, determining concentrations of heavy metals and comparing different location results.
