Sunday Night Movie: Acacia Ants and Ant Acacias

I could do without the patronizing narration, but National Geographic’s footage of Pseudomyrmex acacia-ants is worth your time:

In New Zealand, Argentine Ants Collapse

Argentine Ants have spent the past century following commerce around the world, aggressively subsuming the territories of native ants. However, a study by Meghan Cooling et al out today in Biology Letters reports a dent in the Argentine ant empire: Argentine ants had disappeared from 40 per cent of our sampling sites. In many other [...]

Native trees help an invasive ant push north

Pest insects can be unpredictable, arriving in unexpected places yet failing to show up in regions where they ought to thrive. The famously defensive Africanized honey bees, for example, took more than a decade to move into Florida after establishing in nearby Texas. Argentine ants (Linepithema humile) are a subtropical species from flood plains in the [...]

As you surmised, those little orange balls are an egg-mimicking fungus. It is related to free-living soil fungi, [...]

Surfing around the bookstores this morning I see that the much-anticipated Ant Ecology book is out. At $129.00 it’s not something the casual reader is liable to pick up. Nonetheless, Ant Ecology is a beautiful volume reviewing the state of the field, and scientists who work on ants should probably own a copy. Or at [...]

The other ant-fungi

If I were to mention an ant-fungus mutualism- that is, an ecological partnership between an ant and a fungus that benefits both- most biologically literate people might think of the famed leafcutter ants and the edible mycelia they cultivate.  But that is just one example. Several other fungi have entered into productive relationships with ants, [...]
