Five New Bess Beetles Discovered in Colombia, Bolivia, and Peru

Five New Bess Beetles Discovered in Colombia, Bolivia, and Peru

Paxillus-amati
Beetles in the family Passalidae are one of the few groups of beetles that are subsocial — the adults actually care for their young and nest in decaying logs. Male and female adults pre-chew the wood and feed it to the larvae, which otherwise would not be able to digest it. They can even communicate audibly by rubbing their wings and their abdomens together — an act known as stridulation, which is often associated with crickets and other insects. Even the larvae are able to stridulate.
Five new passalid beetle species from South America were recently found and described in an article published in the Annals of the Entomological Society of America.

Workshop "The use of Phylogenies in the study of Macroevolution - 3rd edition", Barcelona

Registration is open for the course "THE USE OF PHYLOGENIES IN THE STUDY OF MACROEVOLUTION - 3rd edition"

Dates: Septiembre 28 - October 2, 2015.

Instructor: Dr. Juan López Cantalapiedra (Museo de Ciencias Naturales, CSIC, Spain).

This course is aimed at postgraduate students, postdoctoral reserachers and established academics, and can be validated by 4 ECTS at European Universities.

Webpage and registration: http://www.transmittingscience.org/courses/evol/phylogeny-and-macroevolution/ or writing to courses@transmittingscience.org

First, this course will introduce participants to the use, modification and representation of phylogenetic trees. Then, we will focus on the use of phylogenetic information to reconstruct ancestral characters and biogeographic histories, learning how to apply Phylogenetic Comparative Methods. This course will also tackle trait evolution modeling and the assessment of phylogenetic signal. Finally, we will learn about the shape of phylogenetic trees and its evolutionary causes and how to estimate the rates of diversification throughout the evolutionary history of groups. Participants are encouraged to bring their data sets to use in the practical class.
Important note: Please bear in mind that this course is not about reconstructing (building) phylogenetic trees.

Software: Mesquite, FigTree, BayesTraits (using BayesTraits Wrapper in R), RASP and R (ape, TreeSim, TreePar, Geiger, OUwie, BioGeoBEARS).

Place:  Facilities of the CRIP at  Els Hostalets de Pierola, Barcelona (Spain).

Organized by: Transmitting Science, the Centre de Restauració i Interpretació Paleontologic and the Institut Catalá de Paleontologia Miquel Crusafont.

El sitio web Filogenetica.org: llegará a los diez años?


Lo que empezó en el 2006 como una curiosidad por aprender a desplegar un sitio web y la inquietud de proporcionar un servicio de información sobre recursos para filogenética, que es lo que ha llegado a ser este sitio web?
Las circunstancias han cambiado. Ahora es muy fácil encontrar la información en internet. Por eso, amables lectores, les pregunto: vale la pena seguir con este servicio? Llegará este sitio web a su décimo año?
