Download or read book Phylogeny and Floral Host Relationships of Callandrena (Hymenoptera : Andrenidae : Andrena) written by Leah laPerle Larkin and published by . This book was released on 2002 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Callandrena, a subgenus of 80 described species of bees in the genus Andrena (Hymenoptera: Andrenidae) is shown, via phylogenetic analysis of both mitochondrial and nuclear DNA sequence data, to be polyphyletic. The characters previously uniting this group have likely arisen by convergent evolution among unrelated lineages that have independently specialized on flowers of the Asteraceae for pollen consumption. At this time, we cannot definitively state whether there are two or three clades of bees formerly ascribed to Callandrena, nor whether one clade may belong to the European subgenus Chrysandrena as has been proposed, so we do not erect a new subgenus of Andrena at this time. The limits of Callandrena sensu stricto are provisionally delimited based on a single morphological character. The phylogenetic relationships of the two groups relative to other Andrena subgenera are discussed in Chapter 2. In Chapter 3, Clade B, as defined for Callandrena in Chapter 2, is used to investigate the evolution of pollen host choice. Diet breadth is determined by analysis of pollen loads of at least 20 individual females per species. The choice of host and degree of specificity are then mapped onto the molecular phylogeny to investigate the evolution of these traits. Oligolecty appears to be the ancestral state in Andrena; polylecty has evolved several times; and reversals to oligolecty within these lineages have also occurred. Within the oligolectic lineage studied, host shifts were not uncommon. During the course of this study, a number of undescribed species were collected. Five are described in Chapter 4.

Download or read book A Revision of the Bee Genus Augochlora Smith (Hymenoptera; Apoidea) in Southern South America written by Anderson Lepeco and published by . This book was released on 2020 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Lecidea Ach. in its broad sense, is one of the largest and most heterogeneous genus of lichenized fungi with a worldwide distribution and with diversity hotspots located in the temperate and polar regions. The genus belongs to a crust-like microlichen group and inhabits many different substrates (e.g., bark, rock, wood, soil, mosses). Lecidea does not form a coherent systematic entity, and previous studies have revealed it as a polyphyletic assemblage with species spread across various families within the Lecanoromycetes. The present study is a modern taxonomic revision of southern South America non-saxicolous lecideoid lichens based on morphological, anatomical and chemical characters. A total of 27 species belonging to ten genera are recognized. The current study reveals a substantial, previously hidden, diversity of lichens in Valdivian temperate and Magellanic subpolar forests; increasing the number of known lecideoid lichens in the studied area. Many new regional records are also reported including six species new to South America (Bryobilimbia hypnorum, Hertelidea botryosa, H. eucalypti, Japewiella tavaresiana, Placynthiella oligotropha, and Ramboldia brunneocarpa). The following species are here described as new to science: Bryobilimbia flakusii Rodr. Flakus sp. nov. (Argentina), B. pallida Rodr. Flakus sp. nov. (Argentina, Chile), Hertelidea printzenii Rodr. Flakus sp. nov. (Argentina), H. stipitata Rodr. Flakus sp. nov. (Argentina, Chile), "Lecidea" vobisii Rodr. Flakus sp. nov. (Argentina), and Ramboldia australis Rodr. Flakus sp. nov. (Argentina, Chile). All species are described and illustrated in detail, and an identification key to the species is provided. In addition, as a result of a revision of available type material, a list of 48 additional species excluded from this study, including brief remarks on their taxonomical affiliations, is provided"--Page 3.
