Encuesta: Que árboles prefiere?

La primera encuesta de este año es sobre sus preferencias en la selección de arboles óptmos para la reconstrucción filogenética.

Al igual que en la encuesta anterior, pueden elegir más de una respuesta. La lista de opciones y los resultados estarán disponibles hasta Abril en la columna de la derecha. En la lista de opciones he incluido los criterios más conocidos para tener una idea de las preferencias entre la comunidad.

Escriban aquí sus comentarios y sugerencias. Especialmente útil sería saber cuales son los criterios de selección si alguien vota por las opciones "Otro criterio?".

Gracias por participar!

XXth International Seaweed Symposium, Mexico

Ensenada, BC, Mexico

February 2010

You are most cordially invited to the XXth International Seaweed Symposium to be held in Mexico.

The International Seaweed Symposium (ISS) is held every three years under the auspices of the International Seaweed Association (ISA). It is the foremost international meeting on seaweed research and utilization. Scientific research plays a fundamental role in developing seaweed products and industries. The ISS provides a forum for scientists, technologists, industry and resource managers to present their latest research results and develop new synergies.

Scientific Program

The Scientific Program includes plenary sessions, mini symposia, contributed oral or poster presentations, workshops, mid-symposium excursions and pre- and post-symposium tours. Several mini symposia and workshops are planned on topics such as:

1) Genetic engineering of seaweeds;

2) Seaweed cultivation techniques;

3) Marine hydrocolloids;

4) Bioactive compounds;

5) Where are we on systematic of algae;

6) Climate change in seaweeds;

7) Seaweeds for biofuels;

8) Artificial seaweed beds;

9) Seaweed extracts and their applications to higher plants;

10) Nutraceuticals/Cosmeceuticals;

11) Environmental services;

12) Seaweeds for food;

13) Management of natural commercial beds;

14) Implications of large scale cultivation;

15) Invasive species;

16) Kappa cultivation;

17) Seaweeds in integrated aquaculture;

If you would like to participate on any of these topics or propose a new one, please contact us at: contact@xxseaweedsymposium.org

Evolution 150

EVOLUTION 150
WORKSHOP on "Evolutionary Biology: Evolution 150",
celebrating the 150th anniversary of the publication of Darwin's The Origin of the Species,
Cuenca, Spain
15th - 19th March 2009

The British Council in Spain in collaboration with the Spanish Council for Scientific Research (CSIC) is organising a series of scientific workshops to provide opportunities for researchers from the UK and Spain to meet face-to-face for the exchange of ideas, knowledge and information on priority topics and to explore future areas of research and collaboration. The next workshop in this series, entitled Evolution 150, will cover the broad field of evolutionary biology and marks the 150th anniversary of the publication of "The Origin of Species".

For further details and an application form contact Rafael Zardoya rafaz@mncn.csic.es or Peter Holland peter.holland@zoo.ox.ac.uk

Early to mid career researchers wishing to participate should send a completed application form and CV to belen.fortea@britishcouncil.es before December 15, 2008.

Curso "Sistemática e Identificação de Abelhas Neotropicais"
Laboratorio de Biologia Comparada de Hymenoptera
Universidade Federal do Paraná (UFPR)

A UFPR representa um centro de excelência no estudo da sistemática de abelhas na América Latina com profissionais e estudantes trabalhando em diferentes grupos taxonômicos. Tendo em vista a grande necessidade de apoio taxonômico aos trabalhos de ecologia e biologia de abelhas, o curso visa atualizar os participantes na classificação e uso de chaves de identificações. O curso irá permitir ao aluno reconhecer os principais grupos de abelhas da região Neotropical.

Os principais objetivos do curso são: familiarização com a terminologia morfológica específica; uso de chaves taxonômicas para identificação dos principais gêneros; exposição de aspectos da sistemática, biogeografia, biologia, e ecologia; discussão de aspectos metodológicos para amostragem, coleta e preparação dos diferentes grupos de abelhas.

O curso terá lugar no Departamento de Zoologia da Universidade Federal do Paraná, localizado no Centro Politécnico, Jardim das Américas, em Curitiba. O período será de 9 a 14 de fevereiro de 2009.

Principia Taxonomica en CD

Por cortesía de J. Llorente, he recibido un CD conteniendo la colección de libros de Papavero & Llorente: Principia Taxonomica.
Esta versión electrónica de los nueve volúmenes originalmente publicados entre 1993 y 2006 viene en un formato atractivo y muy fácil de navegar. Es una excelente introducción a la historia, fundamentos lógicos, filosóficos y metodológicos de las escuelas de taxonomía biológica.

WHY DOES A METHOD THAT FAILS CONTINUE TO BE USED?

ABSTRACT

As a critical framework for addressing a diversity of evolutionary and ecological questions, any method that provides accurate and detailed phylogeographic inference would be embraced. What is difficult to understand is the continued use of a method that not only fails, but also has never been shown to work—nested clade analysis is applied widely even though the conditions under which the method will provide reliable results have not yet been demonstrated. This contradiction between performance and popularity is even more perplexing given the recent methodological and computational advances for making historical inferences, which include estimating population genetic parameters and testing different biogeographic scenarios. Here I briefly review the history of criticisms and rebuttals that focus specifically on the high rate of incorrect phylogeographic inference of nested-clade analysis, with the goal of understanding what drives its unfettered popularity. In this case, the appeal of what nested-clade analysis claims to do—not what the method actually achieves—appears to explain its paradoxical status as a favorite method that fails. What a method promises, as opposed to how it performs, must be considered separately when evaluating whether the method represents a valuable tool for historical inference.
