“…Numerous authors have postulated that introgression provides a significant avenue for the interspecific transfer of genetic adaptations (1,2,(9)(10)(11)(12)(13)(14). Introgression has also been reported to result in the origin and establishment of new races, varieties, subspecies, or species (2,(15)(16)(17)(18)(19)(20). Although introgression may have occurred in these examples, it is difficult to prove and alternative hypotheses, such as convergence or joint retention of the ancestral condition (symplesiomorphy), are possible.…”

Plant communities in the terrestrial-aquatic transition zone in the paramo of Chingaza, Colombia. High Andean paramo ecosystems are an important water resource for many towns, and major cities in this region. The aquatic and wetland vegetation of different paramo lakes, pond, swamps and bogs was studied according to the classical phytosociological approach, which is based on homogenous stands, but excludes any border phenomena or transitional zone. The present research aimed at determining the aquatic and wetland veg-

“…The vegetation period is restricted by cool temperatures in winter and by submersion in summer (Deil 2005). Littorelletea species are able to grow permanently submerged as mentioned for example for Lilaeopsis macloviana by Affolter (1985). These species belong to the "long growing amphibious fluctuation tolerators" sensu Casanova & Brock (2000).…”

Hierarchical clustering was applied in order to get co-occurrence assemblages. These sets were compared with diagnostic groups defined a priori, life forms and their status in South America (introduced vs native species). In order to detect geographic and climatic distribution patterns of the assemblages, we extracted climatic summary variables from the WorldClim database and performed a principal component analysis (PCA). We detected seven species assemblages with a significant correspondence to diagnostic groups defined a priori (P < 0.01), though their association is relatively low (Cramér's V = 0.49). Native species dominate over adventive ones in each assemblage suggesting low risk of outcompetition by introduced species adapted to these habitats. The annual life form is over represented in most of the cooccurrence groups. Despite the huge temperature and precipitation gradient in the studied transect, plant assemblages are occurring almost along the whole range, supporting the hypothesis of azonality (low dependence on macro-climate). Assemblages defined in this work can be potentially used for further supervised classification strategies in order to define plant community types within vernal pool vegetation.
