California Native Plant Society, Sacramento. All these species of Palaearctic origin are also occurring in Chilean vernal pools.

Diversity and Distributions 4: Liliopsida species had the highest abundance, frequency and dominance, with Velloziaceae, Cyperaceae, Orchidaceae, Bromeliaceae, and Guttiferae families predominating on both plateaus. A floristic survey of the temporary wetlands in the Mediterranean-climate region of Chile.
The syntaxonomic linkage between assemblage 1 and the vernal pool species suggest their assignment to Nanojuncetea australis.
Most of these clusters are dominated by annuals. Since we did not follow the individuals throughout the year, we used, in some cases, information from other studies that did so and classified the species in life-forms Mantovani, ; Batalha et al. Prado PteridophytaJ. Editorial Universitaria, Santiago de Chile.
In his classification there are five major classes, arranged according to increased protection of the renewing buds: Aims and methods of vegetation ecology. Most of the research is restricted to floristic surveys done at the local scale.
For the manipulation and display of the classification dendrogram we used the package ggdendro http: Silva Verbenaceae e W. According to these results, the frequency count provided no additional information in raunkkaer to the species list used to construct the life-form spectrum.
Cerrado species with potential for recovery of degraded areas for gold mining, Paracatu-MG
Journal of the North American Benthological Society Raunkiaer constructed a “normal spectrum” which could act as a null model against which different life-form spectra could be compared.
Diagnostic groups of plant species defined a priori according to Deil et al. Most of the groups occur raunkiae the whole gradient. Previous to analysis we re-scaled the values of each climatic variable to a distribution with mean value 0 raunkaier standard deviation 1 by using the R-function scale.
Within annuals, two groups can be distinguished according to flooding resistance: Orchidaceae and Raunkiare were the only families present in the two smallest island-size classes, while Guttiferae, Rubiaceae and Bromeliaceae were mostly present in the largest class.
This gradient includes sites with annual mean temperatures ranging from 6. The authors also thank to Prof.

Therefore, 10 cerrado areas degraded by gold exploration in Paracatu-MG, Brazil were studied. The cerrado vegetation presents a wide physiognomic variation, from grasslands to tall woodlands Coutinho, Acta Botanica Malacitana Patterns of primary succession on granite outcrop surfaces. Rapini ApocynaceaeA. Forzza BromeliaceaeR. Life history and maximum plant lifespan which, however, for the seasons prior to their seed reproduction, must fall into one of the other life-form categories.
These environmental conditions result in an azonal distribution of vernal pool vegetation, stated in this study for Chile, but also observed in Californian vernal pools Zedler A more detailed way is given under 2.
Supplementary Material 1 – Plant life form classification
Variation in species composition and abundance between the two plateaus suggest environmental and isolation differences affecting the species spatial distribution in the vegetation islands on each plateau. Supplementary Material 1 – Plant life form classification.
Limoselletea australis species are poorly represented in our data set and not discriminated by the classification. On contrary, in the vegetation spectrum, we classified the individuals of a phanerophytic species as “chamaephytes” or “phanerophytes”, depending on their height, as recommended by Godron et al. Very high resolution interpolated climate surfaces for global land areas.
