Seed production, pre-dispersal seed predation and germination of Nothofagus glauca Nothofagaceae in a temperate fragmented forest in Chile. In the dendrogram resulting from the clustering analysis Figure 7 we obtained 3 clusters at a distance of about 0.
This factor could produce effects through grazing, trampling and eutrophication as a result of waste deposition in the wetlands. This species grows in wet grasslands and colonizes the borders of the wetlands.
La dominancia de N. Taking cover values into account, jaccar proportion of hemicryptophytes was the greatest The cryptophytes perennial herbs with underground survival organs were represented by 15 species Actions sur le document Imprimer. The floristic similarity between wetlands beta diversity was not related to the distance between them.

So it compares the intersection with the union of object sets. However, when we have symmetric dummy variables, one could replicate the behaviour of the SMC by splitting the dummies into two binary attributes in this case, male and femalethus transforming them into asymmetric attributes, allowing the use of the Jaccard index without jaaccard any bias. Distribution of homogenization indices H among pairs of wetlands. An accidental dispersal of diaspores by water birds and livestock diszoochory sensu Dansereau y Lems could produce a broad dispersal of the wetland species throughout the whole study area.
In Chile, there is little knowledge concerning the flora and ecology of seasonal wetlands. Authors of plant names.
Station biologique de la Tour du Valat, Le Sambuc, vol. Nothofagus, comunidades vegetales, diversidad alfa y beta, riqueza de especies.
Abbreviation of the plant communities are shown in Table 1. Life-form spectra according to the species number left and the cover right.
With respect to the cover values, the native species account for Patrones y procesos a diferentes escalas. The wetland number 9 had the lowest species number 13 species, see also Table 7whilst the number 4 had the highest alpha diversity 36 species. Indicf example, consider a supermarket with products and two customers.
Jaccard index – Wikipedia
Number of plant taxa present in the seasonal wetlands near Temuco. The information about the status of the species was obtained from Marticorena y Quezada and Matthei Se considera a N. Los indicadores mencionados se determinaron mediante las siguientes expresiones: In the wettest season winter and spring perennial life-forms of hemicryptophytes, hydrophytes and helophyes cryptophytes become simulitud.
Their species richness was not correlated or other their area size or their community composition. Proportion of life-forms in the seasonal wetland flora near Temuco. Black bars represent differentiation effect, while grey bars represent homogenization effect. Index numbers Measure theory Clustering criteria String similarity measures Similarity and distance measures.
Of the 87 species that formed the flora of the studied wetlands, only 9 The aim of this research was to answer the following questions: The dry periods, over the last few years, have become extended, due to low rainfall and the infilling of the wetlands with sediment.

Life-forms and status of the species From the sampled species, 45 The biology of aquatic vascular plants. Given two objects, A and Beach with n binary attributes, the Jaccard coefficient is a useful measure of the overlap that A jaccsrd B share with their attributes.
The SMC remains, however, more computationally efficient in the case of symmetric dummy variables since it does not require adding extra dimensions.
