TRANSCRIPT OF AUDIO
From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of June 22, 2015.
MUSIC – ~6 sec – Excerpt of “March of the Picnic Ants,” by No Strings Attached
This week, we feature a tune for a large group of insects whose image as hard workers fits their widespread impacts. Have a listen for about 35 seconds.
MUSIC – ~35 sec – Excerpt of “March of the Picnic Ants”
You’ve been listening to part of “March of the Picnic Ants,” by No Strings Attached, on the 1999 CD “In the Vinyl Tradition Volume II,” from Enessay Music. Ants are familiar for seemingly non-stop work, big nest mounds, social organization in colonies, and—of course—finding human food at picnics. Scientists categorize ants as a family within the insect group that also includes bees and wasps. The ant family includes an estimated 15,000 species worldwide and perhaps 1000 species in North America. Ants live in colonies in all kinds of land-based, or terrestrial, habitats, with colony workers possibly numbering in the thousands or even the millions in some cases. Ants’ diversity and numbers make them important factors in terrestrial food webs, nutrient recycling, and soil conditioning. But what about ants from a water perspective?
Land and water ecosystems are connected in many ways, so ants’ terrestrial impacts can eventually affect water bodies. While no known ants are aquatic, some species live in wetlands, and for dryland species, moisture and humidity can influence where ants nest and when they leave the nest. Finally, water is a key factor for at least two notorious ant pests: moisture-seeking carpenter ants often nest in damp wood or other materials in human buildings; and Red Imported Fire Ants—South American natives that now infest Virginia and several other southern states—survive flooding of their nests by joining together into water-resistant rafts.
Innumerable, unavoidable, socially networked—lots of things about ants are well-known. But with possibly several thousand species still lacking full scientific description, we don’t yet see the whole anthill. Thanks to No Strings Attached for permission to use this week’s music, and we close with a few more seconds of “March of the Picnic Ants.”
