| Mosses are poikilohydrous non-vascular plants, usually with some degree of desiccation tolerance. Dendroid mosses have conducting tissues that make them analogous to vascular plants. Functional studies on these mosses, however, are scarce. Dendroligotrichum dendroides is a dendroid moss that occurs in Chile in the understory of temperate forests where it can be exposed to summer drought. We studied desiccation tolerance and rehydration capacity on D. dendroides from two populations with contrasting precipitation. We sampled plants from the northern part of their distribution (Contulmo, Araucanía district; lower precipitation), and from a southern population in Katalapi (Los Lagos district; higher precipitation). We measured relative water content and... |

| Chilean vegetation has been described based on dominant trees and shrubs, giving little attention to less conspicuous plants such as pteridophytes sensu lato (ferns and lycophytes). These plants have different ecological demands and reproductive strategies than woody plants and are excellent tools to recognize vegetation zones. In the present study we analyze the distributional patterns of the 124 pteridophyte taxa occurring in continental Chile, regarding species richness and habitat preferences distribution. Using Jaccard’s similarity index and grouping analysis, we obtained 5 pteridophyte zones that are significantly different from each other. Species richness distribution showed unimodal pattern with latitude, increasing from 17º S toward... |
