2007). In Australian dry forests and in different vegetation types of Tasmania, vascular plant selleck kinase inhibitor diversity was used as a potential surrogate for bryophyte and lichen diversity, respectively moss and macrofungus diversity (Pharo et al. 1999; McMullan-Fisher 2008). In this paper, we explore alpha and beta diversity of epiphytic and terrestrial ferns, bryophytes and macrolichens in two montane rain forest of southern Ecuador, and assess the surrogacy value of each group. This is the first study on diversity and distribution patterns

of ferns, bryophytes and lichens in tropical rain forest that separates between terrestrial and epiphytic taxa. Materials and methods Study sites We studied primary upper montane forests on ridges and slopes at 2400–2650 m at three sites: Reserva Biológica San Francisco (RBSF), mountain pass El Tiro, and Tapichalaca Reserve, all situated in the surroundings of Podocarpus National Park in southeastern Ecuador (Fig. 1). RBSF is situated on the southern slope of the San Francisco river valley N of the Cordillera El Consuelo.

Ranging between 1800 and 3140 m, RBSF preserves ca. 1000 ha of montane rain forest and páramo Selleck ABT-737 (Beck et al. 2008). On ridges and upper slopes at 2150–2650 m the shrubby upper montane forest is largely dominated by a single tree species, Purdiaea nutans (Clethraceae) (Gradstein et al. 2008). Mountain Pass El Tiro is situated at ca. 2800 m elevation along the Loja-Zamora road, 15 km W of the RBSF and on the border of Loja and Zamora-Chinchipe provinces, on the crest of the cordillera. Slopes at El Tiro have a very rugged profile with many small ravines overgrown by low-statured, shrubby cloud forest with a wind-sheared canopy. The woody vegetation is diverse. Cerro

Tapichalaca Reserve is situated at ca. 2000–3400 m elevation along the Loja-Zumba road in the Cordillera Real, about 90 km s of the town of Loja and just S of Podocarpus National Park. The area supports montane cloud forest and páramo (Simpson 2004). The woody vegetation is quite diverse 3-oxoacyl-(acyl-carrier-protein) reductase in terms of species composition. Fig. 1 Map of the study region and location of study sites The climate at all three sites is cool and perhumid, with annual precipitation ranging from ca. 3000 mm at El Tiro to ca. 4000 mm at Tapichalaca and over 5000 mm at RBSF (Richter, 2003). Temperature maxima occasionally rise up to 25°C and air humidity drops down to 25% at all three locations between mid October and mid December, when monsoon-induced north-western air streams interrupt the semi-permanent easterly air flow. Soils at all three study sites are poor, acidic cambisols and gleysols (pH 4.6–4.1) (Gradstein et al. 2008). Sampling methods Field research on the distribution of ferns, bryophytes, and macrolichens was carried out from July 2003 to January 2003 and from August 2004 to January 2004. Ten plots (20 m × 20 m; six on ridges, four on slopes) were sampled at RBSF and nine plots (three on ridges, six on slopes) each at Tapichalaca and El Tiro.
