“…We used the nomenclature proposed by Müller [ 37 ] for moss species and that by Hässel de Menéndez and Rubies [ 38 ] for liverworts. To establish the global distribution pattern (GDP) analyses of each species, we followed the proposal of León et al [ 39 ], which is essentially an adaptation of the patterns proposed by Seki [ 40 ] and Villagrán et al [ 41 ]. According to these approaches, species can be classified as: (i) disjunct with South America, South Africa and Europe; (ii) endemic; (iii) pantropical-type Podocarpus ; (iv) austral-Antarctic; (v) cosmopolitan; and (vi) bipolar.…”

Forest canopy-cover composition and landscape influence on bryophyte communities in Nothofagus forests of southern Patagonia

et al. 2020

Bryophytes (liverworts, mosses and hornworts) are one of the most diverse plant groups worldwide but one of the least studied in temperate forests from an ecological perspective. In comparison to vascular plants, bryophytes have a broader distribution and a longer altitudinal gradient, and their influence on the landscape is poorly understood. The objective was to evaluate environmental drivers that can influence bryophyte cover, richness, diversity, and nestedness in different forest canopy compositions in two typical landscapes across the natural distribution of bryophytes in Tierra del Fuego (Argentina). Three natural Nothofagus forest types (pure deciduous, pure evergreen, and mixed deciduous-evergreen) in two landscapes (coasts < 100 m.a.s.l. and mountains > 400 m.a.s.l.) were selected (N = 60 plots). In each plot, we established one transect (10 m length) to measure bryophyte cover (point-intercept method). Data were evaluated using generalized linear mixed models and multivariate analyses. The studied environmental drivers were mainly explained by the microclimate, with higher effective annual precipitation and relative air humidity in the coastal forests and higher soil moisture in the mountain forests. Greater liverwort richness was found in evergreen forests at the mountain (9 species) than at the coastal, while mosses showed higher richness in mixed deciduous-evergreen forests at the coastal (11 species) than at the mountain. However, the expected richness according to the rarefaction/extrapolation curves suggested that it is possible to record additional species, except for liverworts in pure deciduous forests on the coasts. Similarities and differences among the studied forest types and among plots of the same forest type and landscape were detected. These differences in the studied indexes (similarity that varied between 0 and 1) ranged from 0.09–0.48 for liverworts and 0.05–0.65 for mosses. Moreover, these results indicated that pure evergreen and mixed deciduous-evergreen forests presented higher moss cover (10.7% and 10.0%, respectively), mainly in the mountains than on the coast. These outputs highlight the need to explore differences at greater altitudinal ranges to achieve sustainability objectives conservation planning for bryophytes in southernmost forests.

“…La verificación de las especies se comparó con ejemplares de herbario (SGO, Chile y BA, Argentina) y el material estudiado se depositó en el Herbario del Museo Nacional de Historia Natural (SGO). Se determinó el patrón de distribución global y nacional (local) de las especies, considerando la bibliografía utilizada para la determinación de las especies, además de las propuestas establecidas por , , Villagrán et al (2005) y León et al (2014).…”

“…Los resultados expuestos resaltan la alta riqueza de especies briófitas en humedales de la zona austral del país y con rasgos biogeográficos de alto endemismo del cono sur de Sudamérica, patrón que converge con los antecedentes de aumento de especies y endemismo de briófitas hacia el sur del país (Shaw et al 2005, Rozzi et al 2008, León et al 2014, Villagrán 2018.…”

Notas sobre la variación de briófitas entre un bosque pantanoso de Amomyrtus luma y una pradera antropogénica húmeda de Juncus procerus

Las briófitas utilizan hábitats con particulares condiciones microclimáticas, respecto a humedad, temperatura y luminosidad (León-Vargas et al. 2006, Stewart & Mallik 2006). También utilizan diferentes sustratos para establecerse, tales como madera en descomposición, superficies rocosas sombrías, suelo mineral y corteza de árboles; debido a diferencias en el pH, la exposición de la superficie (respecto al sol o viento) y la humedad (Fenton et al. 2015). Los disturbios que modifican el microhábitat de establecimiento pueden ejercer cambios en la presencia o ausencia de briófitas, tanto en bosques (Frego 2007, Fenton et al. 2015) como en humedales (Stapanian et al. 2016), lo que puede estar influido por sus rasgos funcionales (Baldwin & Bradfield 2007, Fenton et al. 2015). Los bosques pantanosos son humedales, en los que su fisonomía está determinada por la presencia de especies arbóreas y arbustivas, que crecen sobre suelos generalmente inundados por agua y pobremente aireados (Ramírez et al. 1996, Correa-Araneda et al. 2011). En Chile, se ha descrito la existencia de bosques pantanosos desde la región de Coquimbo hasta la de Magallanes (Pisano 1977, Ramírez Notas sobre la variación de briófitas entre un bosque pantanoso de Amomyrtus luma y una pradera antropogénica húmeda de Juncus procerus Notes on the variation of bryophytes between a swamp forest dominated by Amomyrtus luma and an anthropogenic wet prairie of Juncus procerus
