Estimados amigos y colegas evolucionistas,
me complace anunciarles que el próximo mes de Enero se celebrará la segunda edición del "Taller Latinoamericano de Evolución Molecular". Tendrá lugar del 17 al 28 de Enero de 2011 en las instalaciones del Centro de Ciencias Genómicas y de la Licenciatura en Ciencias Genómicas del Campus Morelos (Cuernavaca, México) de la UNAM, .
Se trata de un Taller intensivo y GRATUITO dirigido a alumnos de posgrado e investigadores de cualquier institución académica, con alternancia de sesiones teóricas y prácticas (ver programa del TLEM 2011). El taller cubrirá desde aspectos bioinformáticos tales como búsqueda de secuencias homólogas en bases de datos públicas, parseo de archivos de secuencias con Perl y alineamiento múltiple de las mismas, revisando a fondo métodos de inferencia filogenética (distancias, parsimonia, máxima verosimilitud, inferencia bayesiana), de evolución molecular (fechación de clados, selección a nivel molecular) y de genética de poblaciones.
El taller estará impartido por destacados especialistas mexicanos en el área (profesores del TLEM 2011). Contaremos además con la participación de dos destacados investigadores invitados, el Dr. Sergei Kosakovsky Pond (UCSD, USA; desarrollador de HyPhy) y el Dr. Julio Rozas (Universidad de Barcelona, España; desarrollador de DNAsp).
Podrán inscribirse al curso alumnos de doctorado de cualquiera de los Programas de Posgrado de la UNAM o de otras instituciones nacionales o extranjeras, siempre y cuando puedan demostrar que tengan conocimientos básicos del área. Se expedirá un certificado de asistencia a todos los participantes. Este taller es acreditable como actividad académica semestral en los programas de posgrado de la UNAM.
El pre-registro se abrirá el día 5 de Noviembre de 2010 y se cerrará el 5 de Diciembre, efectuándose a través de la página de pre-registro del TLEM 2011.
Queremos agradecer el apoyo económico recibido por parte del Programa de Posgrado en Ciencias Biomédicas de la UNAM y del Programa de Posgrado en Ciencias Biológicas de la UNAM, para traer a los profesores invitados. Asimismo agradecemos el generoso y entusiasta apoyo al TLEM 2011 recibido por parte de los Drs. David René Romero Camarena y Rafael Palacios del Centro de Ciencias Genómicas y de la Licenciatura en Ciencias Genómicas de la UNAM, y por parte del Dr. César Domínguez del Instituto de Ecología de la UNAM.
A los lectores de "noticias en filogenetica.org" les agradezco la difusión de este mensaje entre sus colegas y estudiantes.
Reciban un cordial saludo desde Cuernavaca, México, esperando verles por aquí el próximo mes de Enero.

Course summary
This joint Wellcome Trust-EMBL-EBI advanced course aims to provide researchers with the theoretical knowledge and practical skills required to carry out molecular evolutionary analysis on their own data, as well as on data drawn from sequence databases. The course will combine basic assumptions and ideas fundamental to the field with discussion of cutting-edge methodologies, and is therefore relevant to researchers with a range of different experience levels.
Topics
- interpretation of molecular phylogenetic trees and sequence alignments
- genomics resources, sequence searching and sequence alignments
- phylogeny reconstruction and models
- hypothesis testing in phylogenetics
- coalescent model and inference from population data.
Course organisers
- Nick Goldman (European Bioinformatics Institute, Hinxton, UK)
- Ziheng Yang (University College London, UK)
- Aidan Budd (European Molecular Biology Laboratory, Heidelberg, Germany)
- Alexandros Stamatakis (Heidelberg Institute for Theoretical Studies)
One-semester fellowships for graduate students at NESCent
Graduate Fellowships
The National Evolutionary Synthesis Center is now seeking to include graduate traineeship to our portfolio in facilitating broadly synthetic research to address fundamental questions in evolutionary science. We are offering one-semester fellowships for graduate students to pursue research either with a NESCent sabbatical scholar, working group, or postdoctoral fellow. The research should be in line with the goals of the sabbatical scholar and/or working group and may include integrating datasets, developing databases, performing analyses, programming and software development, etc. Support will not be provided to collect or generate new data. When relevant, graduate students are expected to be full members of working group. Ultimately we expect the graduate student to lead and author aspects of the research.

A response to recent proposals for integrative taxonomy

Abstract:
Several proposals have been launched under the new concept `integrative taxonomy' to frame the future development of species discovery and description. We consider that some of those proposals have failed to be truly integrative, by not acknowledging the limitations of operational definitions of species, by defending some kinds of evidence as universally superior, by considering taxonomy to be irreconcilable with population genetics, or by ignoring that the heterogeneity of evolutionary processes often precludes full character congruence in species. Here we defend a taxonomy where species exist, but not in any particular way everyone might want them to exist; a taxonomy open to data and methods from population biology, phylogeography and phylogenetics, as well as any other discipline providing evidence about the origin and evolution of species. This new taxonomy embraces all the consequences of considering species as lineages of reproductive populations, encouraging the use of as many lines of evidence as possible, but without negating that a single line may also be the only one providing evidence for a particular species. Species cannot only be those reproductive populations showing broad character congruence and/or reproductive isolation, due to the different degrees of character congruence, as well as of reproductive isolation, that result from the heterogeneity of evolutionary processes causing lineage splitting and divergence. Also, any kind of character - and not only those established by tradition or fashion - is potentially relevant as evidence of lineage divergence. To conciliate the authors who only see species supported by broad character congruence as good species hypotheses, we explain how a hypothesis can gain corroboration using single or multiple lines of evidence, even in cases of discordance with other lines of evidence. Finally, we propose guidelines to identify the expected degree of stability (preliminary, unstable, and stable) of species hypotheses. © 2010 The Linnean Society of London, Biological Journal of the Linnean Society, 2010, 101, 747-756.
