phyloseminar.org – February 24th, 1pm (PST)

.

Do not forget to tune in to tomorrow’s phyloseminar where Noah Rosenberg will be speaking about consistency properties of species tree inference algorithms under the multispecies coalescent. February 24th at 1pm PST.

You can watch him live from the comfort of your computer, but you may want to take some minutes before the seminar to set up your computer and microwave some popcorn.

Weightlifting ants

"Oecophylla smaragdina can carry more than 100 times its own body weight while upside down on a smooth surface, thanks to its sticky feet." Image: Thomas Endlein, University of Cambridge via NewScientist

NewScientist posted photographs from the competition held by the UK’s Biotechnology and Biological Sciences Research Council to showcase images of their latest research. In a single iconic image, the first one shows the weight that an ant is capable of carrying and how strong the suction devices in her feet are.

I have blogged about these adhesive devices in the ant’s feets before (called arolia in leet speak, singular arolium), and the very first image I used back then happens to be from the same ant species in the image above.

Blogging at its rawness

Weirdbuglady stuffs a real animal for a change, and shows us the whole process with detail pictures.

Finger puppet!

I agree with her, preparing animals that have the skeleton on the outside is way easier and much more cleaner.

Phylogenetics through videoconferencing

Last night I attended a talk in Lisbon given by Ward Wheeler at the AMNH in New York City and moderated by Frederick Matsen from his home institution in Berkeley, California. The talk was the second on a series of talks in phylogenetics held via videoconferencing.

The idea behind phyloseminar.org is to hold regular live online seminars in phylogenetic methodology open to anyone around the globe. This is a challenge given the time zone differences of the possible participants, but it does makes the whole event fun: I watched it after dinner at 9:00pm; the presenter gave it at his 4:00pm; while the moderator was there after lunch at his 1:00pm. I saw at least one person among the audience that watched it from the future after breakfast in New Zealand the next day at 10:00am. › Continue reading

The Snodgrass Tapes

Here is a hidden treasure in the web.

Robert E. Snodgrass was an American entomologist who published extensively on arthropod anatomy and evolution during the first half of the twentieth century. He was as knowledgeable about arthropod morphology as he was a superb artist– you can see some of his illustrations decorating the banner of this blog. His name is synonymous with insect morphology: his 1935 textbook on the subject (reedited by Cornell University Press in 1993) is still the main reference for any modern course in entomology.

Snodgrass was a lecturer in the University of Maryland for most of his academic life. In 1960, two years before his death, he gave a series of three lectures that were recorded in audio tape. Fortunately for us Jeffrey W. Shultz, professor of entomology at Maryland, has digitized and made these lectures available through a nicely designed page called The Snodgrass Tapes. › Continue reading

Portuguese Evolutionary Biology Meeting- December 21st, 2009

Since I am in the neighborhood:

We are please to announce that the 5th Portuguese Evolutionary Biology Meeting will take place at Instituto Superior de Psicologia Aplicada (ISPA) in Lisbon on December 21st 2009. It is being organized by Unidade de Investigação em Eco-etologia and Centro de Biociências do ISPA (Rua Jardim do Tabaco, 34, Lisbon).

The Portuguese Evolutionary Biology Meetings aim to bring together Portuguese researchers and to promote Evolutionary Biology in Portugal. They are held in late December to allow researchers in foreign institutions to attend, given that many spend their Winter break in Portugal.

Eickwort’s Manual of Insect Morphology

George Campbell Eickwort (1949–1994)

The Department of Entomology at Cornell University saw a time of great research and teaching in insect morphology at the end of the Twentieth Century, most of which came from the efforts by two extraordinary systematists: William L. Brown Jr. and George Campbell Eickwort.

Three succinct reasons why scientists should communicate science to the general public

Raghavendra Gadagkar, social insects biologist, writes:

I believe that most working scientists should spend part of their time explaining and discussing their work with a larger audience. There are at least three important reasons for this. One is that science needs to become an integral and essential part of society and not be perceived as an outside force that is at loggerheads with society. Second, scientists need to recruit the best young minds to make up the next generation and that can only happen if we devote time to communicate with the general public. Third, I have no doubt it will help us appreciate our own work better.
