Participantes del taller de Winclada, Xalapa 2015

Hoy nos reunimos en la Sala de videoconferencias del Edificio A para el taller de Winclada. El Dr. Nixon amablemente aceptó impartir este taller como parte de su viista al INECOL para una Conferencia magistral.

Todos muy puntuales a las 9 am nos dimos a la tarea de repasar métodos de analisis filogenéticos con las varias operaciones implementadas en "Winclada-Asado v. Xalapa", tal como Kevin la denominó aqui esta mañana. Con esta version super nueva, se pueden enviar tareas desde WinClada a TNT, MrBayes y raxML!
Aqui una foto de algunos de los participantes!




Agradecemos a todos los que ayudaron en la organización de este Taller, la Dra. Gabriela Heredia, Celia Lozano, Joaquin Cázares, Juan Chavez, Noe Carmona, Martha Bonilla, Dolores Gonzalez, Carolina Solis y Eleuterio Velasco.

Taller de WINCLADA, Ago 18, 2015, en Xalapa

Taller de WINCLADA

Fecha: Agosto 18, 2015.

Instructor: Dr. Kevin Nixon, Cornell University,

Organizador: Dr. Efrain De Luna, INECOL, Xalapa, México

Lugar: INECOL, Xalapa. Salon de Usos Multiples, Edificio A, segundo Nivel. Biodiversidad y Sistematica,

Horario: 9 am a 3 pm.


Kevin Nixon of the L. H. Bailey Hortorium at Cornell University in Ithaca, New York has written WINCLADA.
Winclada is a full-featured menu and mouse driven WINDOWS program for phylogenetic analysis.
1) Reads Hennig86, NONA, DADA, CLADOS, and most NEXUS format files that contain cladistic data matrices.
2) Allows the user to edit and manipulate data matrices, both morphological and molecular.
3) Displays, manipulates, and prints cladograms (phylogenetic trees). The latest versions also have a print preview function that allows the user to position trees on a page. Several tree styles are supported.
4) Winclada has the standard types of tree manipulation functions, such branch move and collapse, and recalculates tree lengths automatically under the currently selected optimization parameters (e.g., show only unambiguously supported nodes, fast optimization, slow optimization). Character changes can be mapped as colored hashmarks and labeled both by character number or name and states.
5) Winclada can be set up to directly spawn the programs NONA, PIWE, and HENNIG86. Nona is currently the fastest available program for parsimony analysis. NONA is available by download from the WIlli Hennig Society Web site.

A Falsification of the Citation Impediment in the Taxonomic Literature

Current science evaluation still relies on citation performance, despite criticisms of purely bibliometric research assessments. Biological taxonomy suffers from a drain of knowledge and manpower, with poor citation performance commonly held as one reason for this impediment. But is there really such a citation impediment in taxonomy? We compared the citation numbers of 306 taxonomic and 2,291 non-taxonomic research articles (2009-2012) on mosses, orchids, ciliates, ants, and snakes, using Web of Science and correcting for journal visibility. For three of the five taxa, significant differences were absent in citation numbers between taxonomic and non-taxonomic papers. This was also true for all taxa combined, although taxonomic papers received more citations than non-taxonomic ones. Our results show that, contrary to common belief, taxonomic contributions do not generally reduce a journal’s citation performance and might even increase it. The scope of many journals rarely featuring taxonomy would allow editors to encourage a larger number of taxonomic submissions. Moreover, between 1993 and 2012, taxonomic publications accumulated faster than those from all biological fields. However, less than half of the taxonomic studies were published in journals in Web of Science. Thus, editors of highly visible journals inviting taxonomic contributions could benefit from taxonomy’s strong momentum. The taxonomic output could increase even more than at its current growth rate if (i) taxonomists currently publishing on other topics returned to taxonomy and (ii) non-taxonomists identifying the need for taxonomic acts started publishing these, possibly in collaboration with taxonomists. Finally, considering the high number of taxonomic papers attracted by the journal Zootaxa, we expect that the taxonomic community would indeed use increased chances of publishing in Web of Science indexed journals. We conclude that taxonomy’s standing in the present citation-focussed scientific landscape could easily improve – if the community becomes aware that there is no citation impediment in taxonomy.
