A new description was made only in 1916, by Edward Green, an American agronomist who was the superintendent of the Governmental Cotton Service of Brazil, in 1913, on a hill in the municipality of Caicó, State of Rio Grande do Norte (RN Green, 1916). mustelinum but, as there has never been any other report of the species there, it may be a case of incorrect botanical classification. Besides the materials collected by Gardner, Watt refers to another specimen collected in Colombia, by Hutton, in 1853 in La Paila, which he believed to be G. mustelinum was made by Gardner in 1838, who collected seeds and other plant materials in the municipality of Crato, state of Ceará (CE), whose exsiccatae were described by Watt (1907). mustelinum, and the other of white fiber on the margins of the Contas River, where Brazilian native cotton was later localized ( Menezes et al., 2014a). To our knowledge, the first written report about native Brazilian cotton was made by Accioli Bettencourt (1798), who describes the presence of two wild cotton trees, one of brown fiber, probably G. It is sexually compatible with cultivated cotton species therefore, it can be used in cotton breeding and is an important genetic resource ( Pereira et al., 2012). There is no evidence, not even archeological, of domestication and use of G. The species is endemic to Brazil, restricted to the Northeast region of the country, where semi-arid conditions predominate. mustelinum), one of the five allotetraploid species of the genus.
Gene flow is unlikely to be a threat, and communication may foster significantly in in situ preservation.īrazil is the center of origin of Gossypium mustelinum (G. Historical data show that the preserved populations are in regions where sympatry has not occurred in the last 47 years. New climatic modeling shows that new populations can still be found in the Pernambuco semi-arid area, despite the lack of herbarium and germplasm bank information. Endemic to Northeast Brazil, it was known only to grow in semi-arid areas, but expeditions in 2011, 2016, and 2018 localized plants in preservation areas on the coast of Northeast Brazil (in the States of Paraiba and Pernambuco), as predicted before by niche simulations. It is tetraploid and may cross with cultivated cotton.
The native Brazilian cotton Gossypium mustelinum has never been planted.

The openModeller Desktop application is available with Brazillian Portuguese and English translations. The map browser allows you to pan and zoom on the model's map image. The report includes all the details of which algorithm was used, which parameters for the algorithm were changed, which layers were used, the model duration and so on. Clicking on an item in the experiment tree shows a detailed report for that model. Once an experiment is completed the experiment browser presents the list of algorithm profiles and the species names in a tree view. The experiment designer allows you to set up an experiment consisting of multiple species and algorithm profiles. Algorithm profiles let you store the custom parameters you use for running models in a reusable way. Having layers organised in named sets removes the tedium of repeatedly having to select layers from the file system for different model runs. This is for creating named collections of layers for use in modelling experiments.
