ABSTRACT<\/strong><\/p>\n

(Review of Dicranella<\/em> s<\/em>.l<\/em>. (Dicranellaceae) neotropical species). The America Tropical bryoflora is extremely rich, being the Andes northern and Brazilian southeastern the regions with the highest richness and endemism rates. For the Neotropic, there are areas and taxonomic groups that remains scarcely explored in relation to the how much they represent in the biodiversity worldwide. The Dicranella<\/em> (M\u00fcll. Hal.) Schimp. genus was traditionally classified in the Dicranaceae Schimp. family based mainly on morphological characters, however, with the increasement of molecular and phylogenetic studies, the parental relationships, evolution and position of this genus remains uncertain, requiring new circumscriptions. Currently, based on molecular and morphological data, the Dicranella<\/em> genus is included in the Dicranellaceae Stech. family and has approximately 158 species worldwide and 40 species for the Neotropic. However, despite the high number of recorded species, there is a lack of morphological and molecular data and no taxonomic revision to verify the genus validity, its related synonyms and its described species so far. Thus, with this project, we aim to present a taxonomic revision of the Dicranella<\/em> s<\/em>.l<\/em>. species through nomenclatural, morphological and molecular studies for the taxa registered in the Neotropic. Through of consulted bibliographies references, national and international herbaria loans, material type consultations and clustering<\/em> morphological analysis performed by the PAST software, we obtained a total of 634 specimens analyzed and a conclusion of 57 Dicranella<\/em> species occurring to the Neotropic. In addition, of the 57 species found in the neotropical region, 50 presented modifications in relation to their taxonomic and nomenclatural status, requiring 42 lectotypes and 14 probable holotypes involving the name of these species and some their related heterotypic synonyms. The Dicranella hilariana<\/em> (Mont.) Mitt. species, until then were considered cosmopolitan and with high morphological plasticity, through of nomenclatural and morphological analyzes of its material type, presented a reduced geographical distribution, as well as a definitive and standardized characterization of its morphological aspects. For Brazil, 14 Dicranella<\/em> species were considered, with eight endemic from Brazil, three new occurrences (D<\/em>. angustifolia<\/em>, D<\/em>. apolensis<\/em> and D<\/em>. harrisii<\/em>) for the country and more than 40 new occurrences recorded in the Brazilian states, since eight species were known only by the occurrence of their material type and all other species had their geographical distribution in the country increased. The Dicranella<\/em> species occurring in Brazil had preference to the terrestrial substrate (59%) and distribution in the Atlantic Forest phytogeographic domain (54%). A phylogeny, based on the plastidial marker rps4<\/em> and parsimony analysis, is presented herein for the first time in this thesis for the Dicranellaceae family and some Dicranella<\/em> taxa that occur in Brazil. As a result of this phylogenetic analysis, it was observed that the Dicranella<\/em> species which occur in Brazil do not belong to the same clade of Dicranella sensu stricto<\/em>, that is, they came out in a different clade from which the genus species type is inserted. Also based on the morphological and molecular analysis, in this work we proposed likely synonyms among some Dicranella<\/em> species, which could be represented such as the synonymization of D<\/em>. martiana<\/em> in D<\/em>. hilariana<\/em>, in addition the synonymization of D<\/em>. riograndensis<\/em> and D<\/em>. boliviana<\/em> to D<\/em>. pabstiana<\/em>. The achievement of this project allowed to fill some gaps knowledge about Dicranella<\/em> species occurring in the Neotropic, however, further studies are needed, primarily including other biological science areas such as Ecology, Palinology and Ontogeny to Dicranella<\/em> s<\/em>.l<\/em>. species.

RESUMO<\/strong><\/p>\n

(Revis\u00e3o das esp\u00e9cies neotropicais de Dicranella<\/em> s.l<\/em>. (Dicranellaceae)). A brioflora da Am\u00e9rica Tropical \u00e9 extremamente rica, sendo o norte dos Andes e o sudeste do Brasil as regi\u00f5es com as maiores taxas de riqueza e endemismo. Para o Neotr\u00f3pico, ainda existem \u00e1reas e grupos taxon\u00f4micos pouco explorados em rela\u00e7\u00e3o ao quanto elas representam em biodiversidade mundial. O g\u00eanero Dicranella<\/em> (M\u00fcll. Hal.) Schimp. estava tradicionalmente classificado na fam\u00edlia Dicranaceae Schimp. baseando-se principalmente em caracteres morfol\u00f3gicos, no entanto, com o surgimento dos estudos moleculares e filogen\u00e9ticos, as rela\u00e7\u00f5es de parentesco, evolu\u00e7\u00e3o e posi\u00e7\u00e3o desse g\u00eanero permanecem incertas, necessitando de novas circunscri\u00e7\u00f5es. Atualmente, com base em dados moleculares e morfol\u00f3gicos, o g\u00eanero Dicranella<\/em> est\u00e1 inclu\u00eddo na fam\u00edlia Dicranellaceae Stech. e apresenta aproximadamente 158 esp\u00e9cies existentes no mundo e 40 esp\u00e9cies no Neotr\u00f3pico. Contudo, apesar do elevado n\u00famero de esp\u00e9cies registradas, ainda existe uma elevada car\u00eancia de dados morfol\u00f3gicos e moleculares e nenhuma revis\u00e3o taxon\u00f4mica que verifique a validade do g\u00eanero, de seus sin\u00f4nimos relacionados e de suas esp\u00e9cies descritas at\u00e9 o momento. Dessa maneira, com este projeto, temos como proposta de trabalho apresentar uma revis\u00e3o taxon\u00f4mica das esp\u00e9cies de Dicranella<\/em> s<\/em>.l<\/em>. por meio de estudos nomenclaturais, morfol\u00f3gicos e moleculares para os t\u00e1xons registrados no Neotr\u00f3pico. A partir de refer\u00eancias bibliogr\u00e1ficas consultadas, empr\u00e9stimos de herb\u00e1rios nacionais e internacionais, consultas de materiais tipo, an\u00e1lises morfol\u00f3gicas de agrupamento realizadas pelo software PAST, tivemos como resultados um total de 634 esp\u00e9cimes analisados e uma conclus\u00e3o de 57 esp\u00e9cies de Dicranella<\/em> ocorrentes no Neotr\u00f3pico. Al\u00e9m disso, das 57 esp\u00e9cies encontradas na regi\u00e3o neotropical, 50 apresentaram modifica\u00e7\u00f5es em rela\u00e7\u00e3o ao seu status<\/em> taxon\u00f4mico e nomenclatural, sendo necess\u00e1rio designar 42 lect\u00f3tipos e 14 prov\u00e1veis hol\u00f3tipos envolvendo o nome dessas esp\u00e9cies e de alguns sin\u00f4nimos heterot\u00edpicos relacionados. A esp\u00e9cie Dicranella hilariana<\/em> (Mont.) Mitt, at\u00e9 ent\u00e3o considerada cosmopolita e com ampla plasticidade morfol\u00f3gica, a partir de an\u00e1lises nomenclaturais e morfol\u00f3gicas de seu material tipo, apresentou uma distribui\u00e7\u00e3o geogr\u00e1fica reduzida, bem como uma caracteriza\u00e7\u00e3o definitiva e padronizada de seus aspectos morfol\u00f3gicos. Para o Brasil foram consideradas 14 esp\u00e9cies de Dicranella<\/em>, sendo oito end\u00eamicas do Brasil, tr\u00eas novas ocorr\u00eancias (D<\/em>. angustifolia, D<\/em>. apolensis <\/em>e D. harrisii<\/em>) para o pa\u00eds e mais de 40 novas ocorr\u00eancias registradas nos estados brasileiros, j\u00e1 que oito esp\u00e9cies eram conhecidas apenas pela ocorr\u00eancia de seu material tipo e todas as demais esp\u00e9cies tiveram sua distribui\u00e7\u00e3o geogr\u00e1fica no pa\u00eds aumentada. As esp\u00e9cies de Dicranella<\/em> ocorrentes no Brasil tiveram como prefer\u00eancia o h\u00e1bito terr\u00edcola (59%) e distribui\u00e7\u00e3o no dom\u00ednio fitogeogr\u00e1fico da Mata Atl\u00e2ntica (54%). Uma filogenia, com base no marcador plastidial rps4<\/em> e an\u00e1lises de parcim\u00f4nia, \u00e9 apresentada pela primeira vez nessa tese para a fam\u00edlia Dicranellaceae e alguns t\u00e1xons de Dicranella<\/em> ocorrentes no Brasil. Como resultado dessa an\u00e1lise filogen\u00e9tica, foi poss\u00edvel observar que as esp\u00e9cies de Dicranella<\/em> que ocorrem no Brasil n\u00e3o pertencem ao mesmo clado de Dicranella<\/em> sensu stricto<\/em>, ou seja, sa\u00edram em um clado diferente do qual a esp\u00e9cie tipo do g\u00eanero est\u00e1 inserida. Tamb\u00e9m baseado nas an\u00e1lises morfol\u00f3gicas e moleculares, neste trabalho n\u00f3s propusemos poss\u00edveis sinonimiza\u00e7\u00f5es entre algumas esp\u00e9cies de Dicranella<\/em>, podendo ser citadas como exemplo a sinonimiza\u00e7\u00e3o de D<\/em>. martiana<\/em> em D<\/em>. hilariana<\/em>, al\u00e9m das sinonimiza\u00e7\u00f5es de D<\/em>. riograndensis<\/em> e D<\/em>. boliviana<\/em> em D<\/em>. pabstiana<\/em>. A realiza\u00e7\u00e3o desse projeto permitiu preencher algumas lacunas de conhecimento das esp\u00e9cies de Dicranella<\/em> ocorrente no Neotr\u00f3pico, por\u00e9m, mais estudos aprofundados s\u00e3o necess\u00e1rios, de prefer\u00eancia abrangendo tamb\u00e9m outras \u00e1reas da ci\u00eancia biol\u00f3gica como a Ecologia, Palinologia e Ontogenia das esp\u00e9cies de Dicranella<\/em> s<\/em>.l<\/em>.
