Myrmecology

In the comments, Eric Eaton makes an observation: Iâm left wondering (just a little) why Alex has such a beef with Dr. Wilson. This is not the first post taking a jab at Wilson, so while Alex makes an excellent point, Iâm also sensing some underlying issues hereâ¦. Eric is right there's an issue.  It is one many myrmecologists, especially systematists, have been tip-toeing around for a while now. The short version is that Wilson is no longer at the leading edge of myrmecology.  As he has fallen out of step with the practicing research community, his public ant commentary is increasingly at…
Another year passes.  The economy is in the toilet.  Violence spreads in the middle east.  In these trying times, one question must weigh on the minds of concerned citizens: "What's happening in world of ant science?" Of course.  Here are the myrmecological highlights of 2008: The Demise of the Standard Ant.  That is the title of a review by Juergen Heinze, but the idea that our basic conception of how ant colonies work is overly simplistic receives plenty of additional support from the research community.   For instance, Smith et al document the complexity of caste determination in…
Let's take a lesson from the Swiss.  They deem myrmecologists of such great national importance that one once adorned the face of the country's highest currency.  Auguste-Henri Forel and his beloved ants were featured on the 1000 Franc note from 1976 to 1995. Ponder that for a moment. A country reknowned for finance.  Put an ant man.  On their top note.  For two decades. For those interested in more Forel, Antweb has a photo from Forel's extensive collection.  Antbase holds Forel's myrmecological publications.  And if you're one of those weirdos who finds sex more interesting than…
Last week the Howard Hughes Medical Institute announced that they will be funding Danny Reinberg, Shelley Berger, and Juergen Liebig to sequence three ant genomes.  Their interest is research on aging, hoping that solving the puzzle of why genetically identical ant nestmates can either live for a year as a worker or twenty as a queen will unlock some clues to aging in our own species.   I think that's a stretch, but whatever.  We myrmecologists will be able to probe the ant genomes for plenty of other worthwhile reasons. Three species were chosen to represent varying levels of caste…
Atta cephalotes carrying leaves, Ecuador Molecular Phylogenetics and Evolution this morning has the first detailed molecular phylogeny of the leafcutting ant genus Atta.  MaurÃcio Bacci et al sequenced several mitochondrial genes and the nuclear gene EF-1a from 13 of the 15 described species-level taxa, using them to infer the evolutionary history of the genus. This is an important paper.  Atta is the classic leafcutter ant of the new world tropics and a model system for co-evolution among the ants, the fungi they cultivate, and a suite of microbes that either parasitize or protect the…
Neivamyrmex army ants attacking a pavement ant, California I see this morning that Daniel Kronauer has published a review of army ant biology in Myrmecological News.  The paper, among other topics, attempts to straighten out some key terminology: AenEcDo army ant: a connotation free abbreviation that is introduced here to avoid the term "true" army ant. It collectively refers to species in the three subfamilies Aenictinae, Ecitoninae, and Dorylinae and is strictly taxonomically defined. Army ant: any ant species with the army ant adaptive syndrome. Army ant adaptive syndrome: a life-history…
Iridomyrmex reburrus Highlights from the recent technical literature: Savanna ants more resistant to fire than forest ants. Parr & Andersen. 2008. Fire resilience of ant assemblages in long-unburnt savanna of northern Australia. Austral Ecology. doi: 10.1111/j.1442-9993.2008.01848 Abstract: Tropical savannas and rainforests contrast in their flammability and the fire resilience of their associated species. While savanna species generally exhibit high resilience to burning, there is much debate about the fire resilience of forest-associated species, and the persistence of forest patches…
Atta texana queen and worker Ant queens are those individuals in a nest that lay the eggs.  They're pretty important, of course, as without reproduction the colony dwindles and disappears. Understandably, ant-keepers have an interest in making sure their pet colonies have queens.  Conversely, pest control folks trying to get rid of ant colonies need to be sure that they've eliminated queens.  Whether your interest is live ants or dead ants, I'll give some pointers in this post for recognizing queens. In many species the difference between workers and queens is obvious.  Consider the…
A century ago, William Morton Wheeler inked this iconic illustration of the striking polymorphism displayed among members of an ant colony. You may have seen it; Andrew Bourke and Nigel Franks used it as the cover for their 1995 text Social Evolution in Ants. I always assumed Wheeler's figure depicted some exotic tropical marauder ant, a voracious jungle species with massive soldiers for slicing up hapless prey. I don't read captions carefully enough, I guess, because I learned recently that this charismatic creature is actually a local harvester ant, Pheidole tepicana. Not only that, but…
Yesterday I received the sad news that Roy Snelling, one of the most significant figures in modern myrmecology, has passed on. He was on an expedition in Kenya and apparently suffered a heart attack in his sleep. Roy's prolific career as a curator at the Natural History Museum of Los Angeles County produced dozens of studies on the taxonomy of bees, wasps, and especially ants. Among other accomplishments, his works are the primary reference for the honeypot ants of North America, numerous groups of carpenter ants, and the entire Chilean myrmecofauna. Roy was a devoted desert rat, an…
