buy canada goose jacket Fabio vila, from the Universidad Distrital in Bogota, Colombia, visited for a month (18 October 19 November). He identified, evaluated, and circumscribed the species of the neotropical genus Lasiocephalus Willd. ex Schltdl., within the Senecioneae group of Compositae. Since the last reinstatement by Cuatrecasas in 1974, the genus has been without new advances in its systematic. In this way, he is supporting in the taxonomy of the genus for further advances in its phylogeny. His previous research was canada goose outlet 2015 conducted at the Charles University in the Czech Republic. During his stay, vila canada goose outlet in vancouver revised about 400 specimens and the type collections of canada goose shop uk four species of Lasiocephalus. In his revision, he proposed the synonyms by locating two names published in official canada goose outlet the former work of Cuatrecasas: L. caldasensis and L. mochensis, in L. involucratus canada goose outlet los angeles and L. loeseneri, respectively. Thus, he could confirm canada goose outlet online uk the identity of 12 species for Colombia and circumscribe the genus to 20 names in the tropics. He canada goose outlet boston also corrected the older names, since the group was taxonomically canada goose outlet parka considered within Senecio. In addition, he achieved to recognize the morphologic variation of the complex L. otophorus, under infra specific categories by Cuatrecasas. vila’s research will contribute to the canada goose outlet trillium parka black phylogeographic studies in that species in the Andean Range. Finally, the Cuatrecasas Fellowship has made it possible to review all the variation of the genus from Venezuela to Bolivia, and supported the last canada goose outlet location steps for a next issue of the Flora of Colombia. buy canada goose jacket
canada goose factory sale The leaf morphotype GD5 from the Guaduas Formation of canada goose outlet us the Late canada goose outlet florida Cretaceous of Columbia is the focus of Camila Martnez Aguilln research. canada goose factory sale
canada goose coats The research of Camila Martnez Aguilln, from the Universidad de los Andes, Colombia, focuses on dating of plant phylogenies based on the fossil record and molecular data, biogeographical reconstructions and the diversification canada goose outlet black friday sale processes in the Neotropics. Her Master’s thesis focuses on the identification of a leaf morphotype called GD5 from the Guaduas Formation canada goose outlet ottawa of the Late Cretaceous of Colombia, based on morphological and anatomical characters. During her visit to the Smithsonian, Martnez Aguilln focuses on the canada goose outlet price identification of leaf morphotypes and a broad revision of the overall morphology of angiosperms that present a canada goose outlet belgium similar canada goose outlet real morphology as the morphotype GD5 (below). Some of the genera that she revised belong to Menispermaceae, Aristolochiaceae, Fabaceae, Euphorbiaceae and Piperaceae. Once the revision of the cleared leaves was completed, she concluded that the Piperaceae shared more characters with the fossil than any of the other families. paleobotanical collection. Martnez Aguilln then made a wide revision of the order Piperales, including other genera of canada goose outlet legit the families Aristolochiaceae, Hydnoraceae and Saururaceae. Within Piperaceae canada goose outlet hong kong she evaluated the genera Zippelia, Manekia and Verhuellia. Given that Piper is a pantropical genus with around 2,000 species, she decided to describe the leaf architecture of the genus, based on approximately 320 species previously sampled to construct the molecular phylogeny. She started the evaluation of the genus Piper with the paleotropical clades and then she continued with the less representative clades. He analyzed more than 600 collections of Dalechampia from the Neotropics and 57 specimens from Colombia. Overall, he has studied 320 collection of Dalechapia for Colombia from 13 different herbaria, with the material from US corresponding to 15.2 percent canada goose outlet michigan of the total sample, which covers a large time span contributing greatly to his work. Through the study of general collections and types he was been able to clarify numerous species concepts and understand their distributional patterns and morphological variation. Maya Lastra was able to uncover collections representing undescribed species and verify new synonymy and range extensions. He also benefited from using the large collections of literature housed in the Botany Library. canada goose coats
canada goose, from Universidad Icesi, Cali, Colombia, conducted research on the “Geographic Differentiation of Piper Species Complexes along the Choc Region and Central America.” She examined herbarium canada goose outlet uk specimens, including several type specimens, as well as consulted the library and made copies of protologs of all species and their synonyms. She compiled a database with all specimens belonging to the Piper trianae (Piperaceae) complex. The database canada goose outlet london includes geographic information canada goose factory outlet vancouver for 350 entries of which the data will be used to produce distribution maps and predicted localities that need to be visited for a through sampling. A portion of leaf tissue was taken from selected specimens (with permission) to include in future molecular phylogenetic analyses. Many species of this complex are only known from the type collection. In particular a number of them correspond to collections made by Jos Cuatrecasas during his expeditions in Valle del Cauca, Colombia. Type specimens of nine of the 16 species of the complex are at US. Ottonia and Enckea. She was able to identify at least two new species, one from Ecuador (a very distinct taxon of the Peltobryon clade with peltate leaves) and another from Guyana, belonging to the Ottonia clade. canada goose
canada goose uk shop From 16 September to 2 October, Ana Isabel Vsquez Vlez, from Universidad del Valle, Cali, Valle del Cauca, Colombia, studied 70 species canada goose outlet vip of Pilea Lindl. (Urticaceae), 25 of which are distributed in Central America and 45 in South America. These included 91 types, 29 of which are from Central America and 62 from South America, including 31 from Colombia. She built a database recording numerous morphological characters that are useful in the classification of the genus. These include length of masculine and feminine inflorescences, flower size, canada goose outlet number of tepals, size of flower clusters, fruit size; size and shape of leaf cystoliths; stipule size; and presence or absence of pubescence. In total, she was able to study and identify about 200 specimens of Neotropical Pilea. canada goose uk shop
canadian goose jacket The dissertation objectives of Jos D. Ziga, from the Rancho Santa Ana Botanic Garden and Claremont Graduate University, include phylogenetic studies within Sabiaceae and Meliosma, as well as taxonomic work on Neotropical Meliosma. The Cuatrecasas Fellowship allowed him to study the morphological variation of vegetative and reproductive characters in Meliosma, with focus on subgenus Meliosma sect. Lorenzanea, and to study the type collections of Sabiaceae. Ziga studied over 30 type specimens of Neotropical Meliosma and three belonging to Ophiocaryon species. Notes and measurements on reproductive and vegetative morphological features were made for each specimen. When present, flowers were rehydrated and dissected with a light microscope (with https://www.canadagoosejacketsoutsale.com previous consent from herbarium staff) to document with detail floral morphological characters that are of taxonomic importance in these two genera. He gathered label data from type specimens and canada goose jacket outlet uk general collection specimens. This data is already being used to inform future field work. He also annotated the specimens of Central American Meliosma canadian goose jacket.
