New paper out! A nice collaboration.
We explore how olfactory brain structures and receptors evolved across this remarkable group, Heliconiini butterflies.

Evolution of the olfactory system during the radiation of Heliconiini butterflies

Abstract. Sensory system evolution plays a crucial role in shaping species’ interactions with their environment, yet the extent to which olfactory system d

Today´s Guardian has an article about our study on butterfly colors, where we compare butterfly colors in native forest to those in eucalyptus plantations. This is study is a partnership between labs from Denmark, Spain, and Brazil.
www.theguardian.com/environment/...

As forests are cut down, butterflies are losing their colours

The insects’ brilliant hues evolved in lush ecosystems to help them survive. Now they are becoming more muted to adapt to degraded landscapes – and they are not the only things dulling down

Amazing effort! Very cool indeed! And what a cover!

One of the many things I appreciated while a student in the US was the NPR system. KUT had so many amazing programs and people. Sometimes I tune in their online streaming just to fill the saudade I have. There is nothing similar to it in Brazil.

Cool. Thanks for the info. We are training students to help with the monitoring. Too many species to account for, but at least the Parides species is easy to identify. Best of luck with your endeavor. Cheers!

Hi Alan, how often do you walk your transect? I started doing transects this year here in Rio. Our goal is to monitor an endangered butterfly, Parides ascanius. Lots of other butterfly too in the transect, but very very few of our focal species so far. Waiting for spring to kick in.

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

Excellent initiative! I grew up thinking Greenland was huge and larger than the whole of South America.

Besides Trumpf deranged interference in my country, I am down to a new low. I have sent a manuscript for review to (so far) 11 potential reviewers (7 declined; 4 did not respond). I am now bothering a 12th potential reviewer... Any fellow assistant editors out there have had this happening before?

With everything else going on, I'm not sure people realize that Trump's latest tariff on Brazil took things to a new (lower) level

Hi, Alison. There’s a postdoctoral associate in my lab that works with ants AND has done a book for kids. Want to talk to her?

Are you originally from a non-U.S. country interested in doing a postdoc in my lab? We study the evolution of butterfly vision and coloration. The Human Frontier Science Program postdoctoral fellowship Letter of Intent deadline is May 7. Please contact me if interested. www.hfsp.org/funding/hfsp...

Enjoy this great short (9 min) film on the work of Constanti Stefanescu, co-ordinator of the Catalan Butterfly Monitoring Scheme. Such schemes are not only important for the butterfly counts, but also as a social network bringing butterflies to the people.

First visit to a protected area that hosts the endangered butterfly Parides ascanius (Fluminense swallowtail). A small enclave in the heart of highly urbanized West Rio. Its host plant is the trilobed vine depicted here. The other vine is a passionflower plant. Tiger moth is a beautiful Poliopastea.

With some 20,000 species- four times the total diversity of mammals- ants have developed an enormous variety of forms.

This is the soldier of Pheidole absurda, from Texas.

Photo of an angular orange ant in top view, standing on a pure white surface. The ant’s head is rectangular, shiny like glass, and nearly as long as the rest of the body.
