on translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
15 صفحه اولDistribution and dynamics of two ferns: Dennstaedtia punctilobula (Dennstaedtiaceae) and Thelypteris noveboracensis (Thelypteridaceae) in a Northeast mixed hardwoods-hemlock forest.
Dennstaedtia punctilobula and Thelypteris noveboracensis are two native species that often arrest forest succession and reduce understory diversity. As part of a project to examine the feedback between forest understory and canopy dynamics, we studied the patterns of distribution and dynamics of these two fern species in an oak-transition hardwoods-hemlock forest. Dennstaedtia was least abundan...
متن کاملNew combinations in Neotropical Thelypteridaceae
288 new combinations of Neotropical Thelypteridaceae taxa are proposed in order to recognize monophyletic genera, based on the results of the most recent molecular phylogeny of the family, as well as the morphological uniformity of characters for each genus. The new nomenclatural combinations correspond to 186 Amauropelta taxa, 77 species of Goniopteris, and 25 Steiropteris taxa. A key to all n...
متن کاملPhylogeny of Marsileaceous Ferns and Relationships of the Fossil Hydropteris pinnata Reconsidered.
Recent phylogenetic studies have provided compelling evidence that confirms the once disputed hypothesis of monophyly for heterosporous leptosporangiate ferns (Marsileaceae and Salviniaceae). Hypotheses for relationships among the three genera of Marsileaceae (Marsilea, Regnellidium, and Pilularia), however, have continued to be in conflict. The phylogeny of Marsileaceae is investigated here us...
متن کاملThe inXuence of life form on carbon and nitrogen relationships in tropical rainforest ferns
Tropical ferns are characterized by a high diversity of plant life forms, yet there have been few largescale studies on the functional ecology of these diVerent forms. We examined epiphytic, hemiepiphytic, and terrestrial ferns, and asked whether there are diVerences in the mineral nutrition and water relations across diVerent growth forms of a diverse assemblage of species. We measured speciWc...
