Rudimenthos: Revisiòn Darwin, Metagenòmica y la "Nueva Ecologìa"

.....
Éste es una breve revisión de metagenómcia y sus recientes avances en metagenómica y la aplicación de las herramientas de la biología molecular a la ecología. A nuestro entender, los enfoques metagenómicos representan una culminación del legado de Darwin como la aproximación al mundo natural visualizando individualmente a los organismos como el producto de su historia evolutiva delineada por su funcionamiento e interacción con su entorno abiótico y con otros organismos.

PhyloSeminar anuncia: Philippe Lemey speaking on Phylogenetic diffusion models

The next speaker will be Philippe Lemey speaking Friday, July 16
at noon PDT on "Phylogenetic diffusion models and their applications
in viral epidemiology."

Emerging infectious diseases continue to appear all over the world,
and importantly, they have also risen significantly over time after.
Having the potential to quickly adapt to new hosts and environments,
RNA viruses are prime candidates to emerge as global threats to human
health. Their rapid rate of evolution, however, also turns viral
genomes into valuable resources to reconstruct the spatial and
temporal processes that are shaping epidemic or endemic dynamics. In
this seminar, I will highlight recent developments in phylogenetic
diffusion models that tie together sequence evolution and geographic
history in a coherent statistical framework. Both discrete and
continuous phylogeographic models have recently been implemented in a
Bayesian statistical approach. I will position this approach among
other popular phylogeographic methods, and then focus on applications
in viral molecular epidemiology to demonstrate their use. Finally, I
will hint at future extensions that may provide entirely new
opportunities for phylogeographic hypothesis testing.

I hope you will be able to attend this exciting talk.

Marzo 29 en PhyloSeminar: Probabilistic analysis of gene families with respect with gene duplication, gene loss, and lateral gene transfer

On March 29th, phyloseminar.org will present Jens Lagergren speaking
on "Probabilistic analysis of gene families with respect with gene
duplication, gene loss, and lateral gene transfer."
NOTE: the seminar will begin at 10h PST, which is three hours earlier
than the previous seminars.
ABSTRACT
Incongruences between gene trees and corresponding species trees are
common. Gene duplication, gene loss, and lateral gene transfer are
three types of evolutionary events that can cause such incongruences.
I will first describe a probabilistic process that contains standard
models of nucleotide substitutions (i.e., such that underly
probabilistic methods for phylogenetic tree reconstruction) as well as
gene duplication and gene loss. This process takes place in a given
species tree and can be used to reconstruct a gene tree for a gene
family of interest and simultaneously reconcile the gene tree with the
species tree. I will describe the algorithms available for this model
and also describe how they perform on biological data compared to
competing methods. Finally, I will describe an extension of this model
that also contains lateral gene transfer and show how it performs on
synthetic data.


Hope to see you there!

Internship opportunity at the NHM, London

Taxonomy Trainee Scheme: Natural History Museum
As a response to the widely perceived decline in taxonomic and curatorial expertise, the Natural History Museum, London invites expressions of interest for taxonomy trainees. The aim is to enthuse and help train a number of people with a demonstrable interest in taxonomy and museum collections, by giving them an opportunity to learn taxonomic and curatorial skills under guidance from experienced staff in the environment of the Natural History Museum’s world famous specimen collections.
The traineeship will equip you with a range of basic taxonomic and curatorial skills and are suitable for individuals seeking further development in this discipline and who wish to experience this type of work.
This project is intended to be rolled out as a fee paying traineeship, but for the first year, as a trial, a small number of short-term (three month) traineeships will have the fee waived, and instead the Museum will provide daily allowances toward accommodation, subsistence and travel.
Traineeships will be available in the Departments of Botany, Entomology and Zoology. Dates of traineeships are negotiable with supervisors, but must take place between March and October 2010.
Successful applicants will have:

• a good general education to A-level or equivalent
• a demonstrable enthusiasm for natural history
• previous experience, however small, of handling animal or plant specimens
• attention to detail
• the ability to work with others
• the ability to work to deadlines
• a willingness to take on tasks with a positive attitude
• familiarity with standard computer software e.g. Word, Excel.

If you wish to apply, please send a letter outlining you interests, qualities and reasons for applying to the following address not later than 15th March 2010. Please state which department you have a preference for (you may apply to all of them but please make clear how your interests fit with each department).

Taxonomy Traineeship Scheme
The Natural History Museum
Cromwell Road
London SW7 9BD
Email: s.tejani@nhm.ac.uk
The successful candidates will be involved in one of the following projects:
Taxonomy Traineeship Scheme:
1. Botany. Identification of type specimens in the Liverwort Herbarium This project involves tracing which specimens represent type material. It is very strongly taxonomy oriented and provides an opportunity to work in an internationally important botanical collection, learning the core skills of curation as well as specimen-based research.
2. Open Air Laboratory (OPAL) surveys. This is an opportunity to take part in a citizen science project. Some field work is involved and there may be limited week-end work.
3. Taxonomic and curatorial work in the Natural History Museum’s beetle collections. Beetles are the most diverse group of organisms on the planet, and the Natural History Museum’s collections are probably the most comprehensive in the world. The successful applicant will spend three months working on designated taxonomy and curatorial projects in the collections, learning essential skills from the Museum’s renowned team of coleopterists.
4. Taxonomic and curatorial work in the Natural History Museum’s Zoology Department. The Zoology Department's collections comprise 30 million specimens, 22 million of which are in spirit. The successful candidate will experience the diverse challenges of identifying and curating specimens from one, or several, zoological groups possibly including, but not necessarily limited to, fish, birds and lower invertebrates. Please state your preferences in your application.

Hoy en PhyloSeminar: Consistency properties of species tree inference algorithms under the multispecies coalescent

Noah Rosenberg
February 24th, 13h PST
http://phyloseminar.org/

Abstract:
The topologies of gene trees that evolve along the branches of a
species tree need not match the species tree topology. As a result of
this discordance, when gene tree evolution is assumed to follow a
"multispecies coalescent" model, simple phylogenetic algorithms can
exhibit peculiar statistical inconsistencies in inferring species
trees. This talk will examine the statistical consistency under the
multispecies coalescent of several algorithms - based on consensus
trees, ranked gene trees, and the "minimize deep coalescences"
algorithm. A summary will be presented of the known consistency
properties of the various algorithms.

ABSTRACT

A method for the direct use of aligned landmark data (2D or 3D coordinates of comparable points) in phylogenetic analysis is described. The approach is based on finding, for each of the landmark points, the ancestral positions that minimize the distance between the ancestor/descendant points along the tree. Doing so amounts to maximizing the degree to which similar positions of the landmarks in different taxa can be accounted for by common ancestry, i.e. parsimony. This method requires no transformation of the aligned data or the results: the data themselves are the x, y, z coordinates of the landmarks, and the output of mapping a character onto a given tree is the x, y, z coordinates for the hypothetical ancestors. In the special case of collinear points, the results are identical to those of optimization of (continuous) additive characters.

TreeVector: Scalable, Interactive, Phylogenetic Trees for the Web

Pethica R, Barker G, Kovacs T, Gough J, 2010. TreeVector: Scalable, Interactive, Phylogenetic Trees for the Web. PLoS ONE 5(1): e8934. doi:10.1371/journal.pone.0008934

We introduce TreeVector, a Scalable Vector Graphics–and Java-based method that allows trees to be integrated and viewed seamlessly in standard web browsers with no extra software required, and can be modified and linked using standard web technologies. There are now many bioinformatics servers and databases with a range of dynamic processes and updates to cope with the increasing volume of data. TreeVector is designed as a framework to integrate with these processes and produce user-customized phylogenies automatically. We also address the strengths of phylogenetic trees as part of a linked-in browsing process rather than an end graphic for print.
.......
TreeVector is a robust, open source software product for the biological community. Phylogenetic trees can be plotted from data files generated from popular software using the NEXUS format producing scalable vector graphics. TreeVector represents a significant advance on existing software, making use of standards and technologies which may not have been established when previous products were developed. Specifically TreeVector offers new levels of flexibility and interactiveness lending itself well to dynamic web-based implementations.
