En la presente contribución se brinda una versión actualizada del 'Catálogo de las plantas vasculares del Cono Sur' de Sudamérica (Argentina, sur del Brasil, Chile, Paraguay y Uruguay), once años después de la publicación de su versión original. Actualización del Catálogo de las Plantas Vasculares del Cono Sur. In addition, two digital appendixes are included, one with the new version of the catalogue, the other with a summary of the flora for each country. Tables sumarizing the floristic information for the Southern Cone and for each country are included, distinguishing by higher groups, families and genera a comparison with the original version of the catalogue is conducted endemic families and genera are specified, as well as the introduced ones finally floristic relationships between the involved countries are evaluated. The number of species is 1238 higher than that registered for the original version, which shows the large number of floristic and taxonomic news published for the area, and the importance of keeping this information updated. This checklist includes nowadays 289 families, 2813 genera, and 18931 species. A summary of all Lycophyta, Monilophyta, Gimnospermae, and Angiospermae (Monocotyledoneae and Dictotyledoneae), updated to July 2019, is here presented.

#Jade dynasty 2019 update#

Ecological niche modelling analysis showed several overlap areas between species in the current model and a greater expansion of the distribution range of the invasive species in future climate change scenarios.Īn update of the 'Catalogue of the vascular plants of the Southern Cone' of South America (Argentina, southern Brazil, Chile, Paraguay, and Uruguay) is here summarized, eleven years after the publication of the original treatment. polymorphum presented a low association with abiotic factors, suggesting possible difficulties in adapting to future environmental changes. Morphological variability of the native T. repens responds to precipitation and temperature factors, which could explain its invasive behavior in a wide range of environments.

Our results showed that leaf morphology of T.

Morphological traits along abiotic and geographical gradients were analyzed, predictive distribution and current and future niches were modelled. A morphometric study was carried out using herbarium specimens that were then georeferenced to obtain environmental and distributional data. In this study, morphological variability patterns associated with abiotic factors were evaluated in Trifolium polymorphum, a native species distributed from southern Brazil to northern Patagonia, and Trifolium repens, a species introduced as an important forage crop and naturalized in diverse environments of southern South America. Previous studies compared native and alien invasive species in their ability to modify their morphology in reaction to climatic and edaphic factors however, taxonomically close species have been scarcely analyzed. The ability of a species to colonize new geographical areas is closely related to its morphological response to environmental gradients.
