Natalia G. Armando, Jorge A. Marfetán & Patricia J. Folgarait. The aim of this work is the morphological and molecular identification of five species of Trichoderma associated with leaf-cutting ant nests of the genera Acromyrmex present in Argentina. The species identified were T. lentiforme, T. inhamatum, T. virens, T. koningiopsis and T. aff. neotropicale resulting in the first record of T. lentiforme and T. inhamatum associated with leaf-cutting Acromyrmex ants, in particular with Acromyrmex lobicornis and Acromyrmex lundii for the first one and with A. lobicornis for the second one. Moreover, T. lentiforme represents the first record for Argentina. In this work we extend the measurements of the conidia and the conidiophore and contribute with additional of the distribution of the species of Trichoderma in this country. Photographs illustrating conidiophores, conidiogenous cells, conidia, and colony phenotype are provided for each species.","PeriodicalId":39378,"journal":{"name":"Darwiniana","volume":"70 1","pages":"72-82"},"PeriodicalIF":0.0,"publicationDate":"2017-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89932793","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}

Luzia Márcia de Araújo1, Adriano Valentin-Silva1, Geraldo W. Fernandes2 & Milene F. Vieira1 Studies on the reproductive biology of Dorstenia species are scarce. We analyzed the sexuality, floral biology, and diaspore dispersal of Dorstenia arifolia and D. bonijesu, including their breeding systems and pollinators, in natural populations from Minas Gerais state, southeastern Brazil. We report here, for the first time, the occurrence of both unisexual (male) and bisexual coenanthia on the same individuals of Dorstenia arifolia, while only bisexual coenanthia were observed in D. bonijesu. In both species all coenanthia were long-lived and bisexual coenanthia were protogynous. We observed the occurrence of self-compatibility and myophily in Dorstenia arifolia, a species which was pollinated by small Lauxaniidae flies. Those insects not only used pollen as food resource but they also used coenanthia as oviposition sites, which is the first report to the studied species. Dorstenia bonijesu produced seeds, even having no floral visitors, suggesting an apomictic mechanism, which is a new breeding system reported to the genus. Both studied species are autochorous, but D. bonijesu also exhibited a peculiar type of hydrochory. The novelties reported herein indicate the need of additional studies to improve the understanding of the reproductive attributes of Dorstenia species.","PeriodicalId":39378,"journal":{"name":"Darwiniana","volume":"290 1","pages":"83-92"},"PeriodicalIF":0.0,"publicationDate":"2017-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84167594","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}

Flores; Santiago A. Catalano & Guillermo M. Suárez The first comprehensive phylogenetic analysis of the Cryphaeaceae (Bryophyta), a pleurocarpic moss family, is conducted on the basis of morphological characters. The data set comprised 73 characters: 10 continuous and 63 discrete. Taxon sampling involved nine genera and 46 species of Cryphaeaceae, 32 species belonging to Cryphaea. Outgroup sampling included 23 species from 21 genera and 13 families of pleurocarpous mosses. The phylogenetic analyses were conducted using parsimony as the optimality criterion following an implied weighting approach. The results did not support the monophyly of Cryphaeaceae as it excluded Dendroalsia abietina from the family. The clade composed of the remaining genera (clade A) was diagnosed by a short seta (0.26-0.30 mm), costa present throughout the innermost perichaetial bract, conical operculum and appressed leaves in dry condition. The analyses furthermore recovered Cryphaea as paraphyletic and Dendrocryphaea as polyphyletic. Cryphaea included Schoenobryum concavifolium, Cyptodontopsis leveillei, and Dendrocryphaea lamyana which were thereby separated from the other species of Dendrocryphaea. Character mapping revealed that, as a consequence of the unexpected placement of crucial species, diagnosis should be considerably modified.","PeriodicalId":39378,"journal":{"name":"Darwiniana","volume":"66 1","pages":"51-64"},"PeriodicalIF":0.0,"publicationDate":"2017-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83123173","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}

M. Paula Quiroga1, Andrea C. Premoli2, Alfredo Grau3 & Lucio Malizia4 Congener species with incomplete reproductive barriers that coexist along environmental gradients may be prone to ecological divergence, in spite of the potential for hybridization in sympatry. We analyzed distribution patterns of isozymes, plastid, and nuclear DNA sequences at regional and local scales in three timber Cedrela species of the subtropics in the northern Argentina (Cedrela angustifolia, C. balansae, and C. saltensis), to test whether populations of distinct species have diverged in montane habitats in relation to their ecological characteristics. Cedrela balansae and C. angustifolia can be identified by diagnostic isozyme alleles. Nuclear ITS sequences yielded intraindividual polymorphism; ambiguous bases were shared between C. balansae and C. saltensis while those of C. angustifolia were part of its intraspecific polymorphism. Chloroplast DNA consisted mainly of a low-elevation haplotype present in C. balansae and C. saltensis and other found in C. angustifolia which in turn was shared locally by all species in sympatry. Multivariate UPGMA analysis of isozymes and Bayesian phylogeny of haplotype ITS yielded concordant patterns. Populations of C. angustifolia clustered in one group and were separated from the rest whereas those of C. saltensis and C. balansae were grouped together in one cluster. This indicates that stronger reproductive barriers exist between C. angustifolia and the low-elevation taxa C. saltensis and C. balansae which seem to maintain continuous gene flow. Nonetheless, under particular environmental settings, i.e., the three species hybridized sometime in the past and later became differentiated through ecological divergen","PeriodicalId":39378,"journal":{"name":"Darwiniana","volume":"4612 2 1","pages":"195-211"},"PeriodicalIF":0.0,"publicationDate":"2016-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76884637","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}
