Phylogeny of the fern genus Melpomene (polypodiaceae) inferred from morphology and chloroplast DNA analysis


Lehnert, M; Kessler, M; Schmidt-Lebuhn, A N; Klimas, S A; Fehlberg, S D; Ranker, T A (2009). Phylogeny of the fern genus Melpomene (polypodiaceae) inferred from morphology and chloroplast DNA analysis. Systematic Botany, 34(1):17-27.

Abstract

Guided by systematic studies on Melpomene, we tested the monophyly of the genus by analyzing sequences of cpDNA (atpβ, rbcL) and morphological characters for 24 of the 29 recognized species. The atpβ data did not yield any resolution of the investigated group. The other data sets each supported the monophyly of the genus, as did all data combined, and indicate it to be sister to the Lellingeria apiculata group as proposed in previous studies. While the morphologically distinct M. leptostoma and M. gracilis are basal lineages with long branch lengths, most of the relationships within the core genus are weakly supported and have very short branch lengths. This indicates a recent radiation of the genus in the northern Andes, its center of diversity, apparently under the influence of the fast up lift of the mountain range and of glacial fluctuations of the vegetation zones, with subsequent dispersals to the Guyana Highlands, the Brazilian shield, and Africa.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
