Ant colony

An ant colony, also called a formicary. is the basic family unit around which ants organize their lifecycle. Ant colonies are eusocial, and are very much like those found in other social Hymenoptera, though the various groups of these developed sociality independently through convergent evolution. The typical colony consists of one or more egg-laying queens, a large number of sterile females ("workers") and, seasonally, a large number of winged sexual males and females. Periodically, swarms of the winged sexuals (known as alates) depart the nest in great nuptial flights. The males die shortly thereafter, along with most of the females. A small percentage of the females survive to initiate new nests.

Supercolonies

Until 2000, the largest known ant supercolony was on the Ishikari coast of Hokkaidō, Japan. The colony was estimated to contain 306 million worker ants and one million queen ants living in 45,000 nests interconnected by underground passages over an area of 2.7 km² (670 acres). In 2000, an enormous supercolony of Argentine ants was found in Southern Europe (report published in 2002). Of 33 ant populations nested along the 6,004-kilometre (3,731 mi) stretch along the Mediterranean and Atlantic coasts in Southern Europe, 30 belonged to one supercolony with estimated millions of nests and billions of workers, interspersed with three populations of another supercolony. The researchers claim that this case of unicoloniality cannot be explained by loss of their genetic diversity due to the genetic bottleneck of the imported ants. In 2009, it was demonstrated that the largest Japanese, Californian and European Argentine ant supercolonies were in fact part of a single global "megacolony".

Fire ant

Fire ant is the common name for several species of ants in the genus Solenopsis. They are, however, only a minority in the genus, which includes over 200 species of Solenopsis worldwide. Solenopsis are stinging ants and most of their common names reflect this, for example, ginger ants and tropical fire ants. Many species also are called red ants because of their light brown colour, though species of ants in many other genera are similarly named for similar reasons. Examples include Myrmica rubra and Pogonomyrmex barbatus.

None of these names applies in all countries nor to all species of Solenopsis, nor only to Solenopsis species; for example the colloquial names for several species of weaver ants in the genus Oecophylla in Southeast Asia include "fire ants" because of their red color and painful sting; the two genera, however, are not closely related. Also, Wasmannia auropunctata is commonly called the "little fire ant."

Appearance

The bodies of mature fire ants, like the bodies of all typical mature insects, are divided into three sections: the head, the thorax, and the abdomen, with three pairs of legs and a pair of antennae. Fire ants of those species invasive in the United States can be distinguished from other ants locally present, by their copper brown head and body with a darker abdomen. The worker ants are blackish to reddish, and their size varies from 2 to 6 mm (0.079 to 0.236 in). In an established nest these different sizes of ants all are present at the same time.

Mystery meat navigation

Mystery meat navigation (also known as MMN) is a disparaging term coined in 1998 by Vincent Flanders, author and designer of the website Web Pages That Suck, to describe a web page where the destination of the link is not visible until the user points their cursor at it. Such interfaces lack a user-centered design, emphasizing aesthetic appearance, white space, and the concealment of relevant information over basic practicality and functionality.

The epithet "mystery meat" refers to the meat products often served in American public school cafeterias whose forms have been so thoroughly reprocessed that their exact types can no longer be identified by their appearances: like them, the methods of MMN are clear to the producer but baffling to the consumer.

Flanders originally and temporarily described the phenomenon as Saturnic navigation in reference to the Saturn Corporation, whose company website epitomized this phenomenon. Flanders writes, "The typical form of MMN is represented by menus composed of unrevealing icons that are replaced with explicative text only when the mouse cursor hovers over them".

Colony

In politics and history, a colony is a territory under the immediate political control of a state, distinct from the home territory of the sovereign. For colonies in antiquity, city-states would often found their own colonies. Some colonies were historically countries, while others were territories without definite statehood from their inception.

The Metropolitan state is the state that owns the colony. In Ancient Greece, the city that founded a colony was known as the metropolis. "Mother country" is a reference to the metropolitan state from the point of view of citizens who live in its colony. There is a United Nations list of Non-Self-Governing Territories.

Unlike a puppet state or satellite state, a colony has no independent international representation, and its top-level administration is under direct control of the metropolitan state.

The term informal colony is used by some historians to refer to a country under the de facto control of another state, although this term is often contentious.

Deborah M. Gordon

Deborah M. Gordon (born December 30, 1955) is a biologist at Stanford University.

Major research

Gordon studies ant colony behavior and ecology, with a particular focus on red harvester ants. She focuses on the developing behavior of colonies, even as individual ants change functions within their own lifetimes.

Gordon's fieldwork includes a long-term study of ant colonies in Arizona. She is the author of numerous articles and papers as well as the book Ants at Work for the general public, and she was profiled in the New York Times Magazine in 1999.

Education

Gordon received a PhD in zoology from Duke in 1983, an MSc in Biology from Stanford in 1977 and Bachelors from Oberlin College, where she majored in French.

She was a Junior Fellow of the Harvard Society of Fellows.

Awards and recognition

In 1993 Gordon was named a Stanford MacNamara Fellow. In 1995 Gordon received an award for teaching excellence from the Phi Beta Kappa Northern California Association. In 2001 Gordon was awarded a Guggenheim fellowship from the John Simon Guggenheim Memorial Foundation. In 2003, Gordon was invited to speak at a TED conference. She is also an adviser to the Microbes Mind Forum.
