Not yet winter break for me

Friday, December 18th, 2009 | Administrative, Comparative Anatomy | Comments Off on Not yet winter break for me

Forget the Friday winter break parties at the workplace, I’m stuck at home preparing slides for a short talk I’ll be giving on Monday. I’m not complaining though. This is the Portuguese meeting on evolutionary biology I mentioned earlier. The odd date (the 21st of December for the past four years) is to accommodate all the nationals pursuing Ph.D.s and postdocs abroad that come home during the holidays.

The meeting is organized by young researches, and this year will be specially interesting because there will be a discussion about creating a national society of evolutionary biologists.

I will be talking about the evolution of mouthparts within ants, covering some fascinating new discoveries that I haven’t share here yet but will blog about some time in the near future. In the mean time, here are a couple of my slides.

Archetype turns one year old

Thursday, November 19th, 2009 | Administrative, Metablogging | 11 Comments

roberto kellerI have now been keeping this blog for as long as it takes the Earth to makes a full revolution around the Sun. And for some strange cultural reason, this entitles me to reflect about it.

It has been a highly enjoyable experience so far. My readership has grown beyond my modest expectations, currently averaging about 100 visitors a day. I have gotten the most traffic whenever one of the much more popular bloggers direct readers to this site– this has been specially so everytime I get the Myrmecos bump, but there are a few other people to thank.

When I started, I decided that if I could post at least once a week I would be satisfied (so far the case). › Continue reading


Blogging will resume in early September

Archetype is about to get even quieter.

Grant proposals have been dealt with (more or less), and next week I will be in Turin, Italy, for the congress of the European Society for Evolutionary Biology. I just don’t want to won’t have time to blog during the congress, unfortunately.

But do not fear, for I leave you with a very tough quiz. Let see if someone knows what’s depicted below. A couple of tips:

– It is one of the few sclerites (skeletal pieces) in adult workers that is completely internal.

– It comes in pairs (left one pictured).

The answer will be revealed upon my return.

Nominate Archetype for The Open Laboratory 2009

Tuesday, July 21st, 2009 | Administrative | 7 Comments

Do you like any particular post(s) from this blog? If so, I will be very grateful if you submit them for consideration to the 2009 edition of the science anthology The Open Laboratory: The Best Writing on Science Blogs by using the form accessible through the link below or the (smaller) one in the right margin.

And if I make it into the final cut due to your submission, you will receive a T-shirt… no, wait, a button… no, hmm… well I’ll think of something involving tiny ants magnified to huge proportions using an electron gun.

Running title: Obligatory why-I’m-not-posting post

Friday, July 17th, 2009 | Administrative | 4 Comments

To draft the apologetic post bloggers should follow the following structure and instructions. You may add further headings if necessary.

1.1. Post overview (Address your readers in a clear and concise way. Maximum 280 characters)

Regular readers of this blog know that I am a slow blogger to start with. I am comfortable with this style of blogging and hope you appreciate the effort I put into my posts. That said, you may have noticed a change from slow to plain sluggish in the past couple of weeks.

1.2. Post explanation (Describe your excuse for not posting. Maximum 380 characters)

I have some large grant application deadlines coming fast my way (that is, as opposed to my manuscript deadlines that are long gone). These are crucial deadlines– success or failure in securing research funding will determine if I keep posting about insect morphology and evolution or if the topic of this blog changes to something like Archetype: insect taxonomy on a budget.

1.3. Relevance of your blog (In detail describe why your readers should keep subscribing to your feed. Maximum 60 characters)

Wha… 60 characters, are you serious! That is not enough to

1.4. Future prospects (Make up a promise in order to incite false hope among your readers. Maximum 220 characters)

I’ll keep posting any interesting things that come by and, as a break for myself, I promise will definitely assemble one regular morphological post with lots of nice images during the next few days. Stay tuned.
