Las Champas and Bebe de La Troya sites show botanical macro remains that allow inquiring into the role of these vegetables in funerary practices and its implications within societies of Catamarca during the late period. Our aims are to characterize social practices involved in the presence of plant remains as grave goods, identifying cooking processing on these remains, trying in this way to go beyond the taxonomic identification. In both archaeological sites, plant macroremains and soil samples were analyzed with naked eye, stereo-binocular microscope, and transmitted light microscope. Archaeological plant samples were taxonomically identified based on diagnostic characters and post-harvest processing practices were detected following ethnoarchaeological features. At Las Champas site Cucurbita aff. maxima subsp. maxima and Chenopodium quinoa var. melanospermum seeds with processing features, together with a Lagenaria siceraria artifact were recovered. Grasses and cf. Zea mays microremains were present in soil samples. At Bebe de La Troya, Cucurbita aff. maxima subsp. maxima seeds and Prosopis sp. endocarps without processing features were identified. These results enable to suggest the presence of seeds, food and clothes as grave goods. These three ways of plant deposits show different intentional funerary practices as well as allow inquiring into culinary and agricultural aspects of later societies of Catamarca province.","PeriodicalId":39378,"journal":{"name":"Darwiniana","volume":"78 1","pages":"125-143"},"PeriodicalIF":0.0,"publicationDate":"2014-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84066677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four Petunia species that grow in Southern Brazil were studied: P. bonjardinensis, P. reitzii, P. integrifolia subsp. depauperata, and P. exserta. We presented a preliminary study on the genetic diversity of five populations of Petunia, using allozyme markers. For the genetic analyses, allozyme electrophoresis was carried out and eight enzyme systems were reliably scored. Standard measures of allozyme diversity were calculated. The highest genetic diversity and the highest fixation index was found in the two studied populations of P. bonjardinensis (P = 90, Â p = 2.2 and 1.9, e H ˆ = 0.33 and 0.30, F = 0.31 and 0.27); this species occurs in small isolated patches, that may restrict gene flow among populations. Petunia reitzii showed the second highest genetic diversity values (P = 78, Â p = 1.78, e H ˆ = 0.28), and Petunia integrifolia subsp. depauperata showed moderate values (P = 40, Â p = 1.4 and e H ˆ = 0.11). Petunia exserta did not show any polymorphic locus. Our results show the urgency of preserving the studied population of P. exserta that did not show any allozyme variation and occurs in a very particular and threatened habitat.","PeriodicalId":39378,"journal":{"name":"Darwiniana","volume":"41 1","pages":"220-226"},"PeriodicalIF":0.0,"publicationDate":"2013-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81008716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A morphological gap between both species is absent in some populations; in addition, intermediate forms have been recognized and described as hybrids. The aim of this work is to examine the genetic variation in populations of Escallonia alpina and E. rubra, and to analyze if there is a correspondence between genetic and morphological variability. We studied the morphology of 39 individuals belonging to five populations, which were also used to perform an AFLP analysis. We conducted ordination, clustering and Bayesian assignment analyses to investigate the relationship among individuals, we calculated genetic diversity indices and performed a Mantel test. As a result of the morphological analysis, two populations were assigned to each species, while the remaining population could not be assigned unequivocally to any of the two species, as the individuals exhibited an intermediate morphology. A strong correspondence between traditional morphological characters and the AFLP pattern was observed. Our preliminary morphological and molecular evidence support Escallonia alpina and E. rubra as two distinct species. The variability found in the intermediate population might be the result of inter-specific hybridization or incomplete lineage sorting.","PeriodicalId":39378,"journal":{"name":"Darwiniana","volume":"64 5 1","pages":"227-236"},"PeriodicalIF":0.0,"publicationDate":"2013-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79278928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
