Attracting Predators without Falling Prey: Chemical Camouflage Protects Honeydew‐Producing Treehoppers from Ant Predation
A network of model 'keystone' food webs connected by dispersal was used to determine how environmental variability and dispersal affect compensatory dynamics (a kind of time-sharing agreement for resources) among competing species. Strong environmental variability ...
Strategic Aspects of Communication

Isolation of a pyrazine alarm pheromone component from the fire ant, Solenopsis invicta
Abstract Alarm pheromones in social insects are an essential part of a complex of pheromone interactions that contribute to the maintenance of colony integrity and sociality. The alarm pheromones of ants were among the first examples of animal pheromones identified, primarily ...

What does an ant genome look like?
Bits and pieces of an ongoing project to sequence the genome of the leafcutter ant Atta cephalotes have started going up on Genbank- Have a look!
Fire Ant Treatment Chemical Control
11 Mar 2010 ... Chemical insecticides (both “organic” and man-made or synthetic products) continue to be the main method of battling fire ants. Insecticides registered by the EPA are considered to pose minimal risk to the user and the ...

Researchers recreate attack-ant chemical
29 Oct 2009 ... UC BERKELEY (US)—A research team has synthesized chemical molecules that trigger normally friendly ants to turn on each other and attack, a finding that may lead to new tactics for controlling the spread of invasive ant ...
Chemical causes ant infighting
28 Oct 2009 ... Researchers have discovered a way to turn normally friendly ants against each other, by interfering with their chemical recognition.
Sequencing Effort to Chart Ants and Their Ecosystem
By sequencing genomes of all the major players, we can study the evolution of the system,” says Cameron Currie, ... “This information will ultimately allow evolutionary biologists to understand how the ants and microbes have adjusted ...
Which ants should we target for genome sequencing?
15 Jan 2009 ... A great deal has been learned about insect navigation in this desert ant. A genome project would allow researchers a very powerful toolkit for probing at a molecular level how ants process information. ...

The evolution of genome size in ants
Despite the economic and ecological importance of ants, genomic tools for this family (Formicidae) remain woefully scarce. Knowledge of genome size, for example, is a useful and necessary prerequisite for the development of many genomic ...
HHMI News: What Can Ants Teach Us About Aging and Behavior?
20 Nov 2008 ... One of the first goals of their collaboration is to work with other researchers to deliver the first complete sequence of an ant genome. The group plans to sequence the genomes of three ant species in all. ...
Chemical cues warn ants of invaders
5 Mar 2008 ... For Stephen Martin from the University of Sheffield, the lead author the study, ant chemical warfare and communication has been a career-long fascination. 'We started off looking at cuckoos - ants that lay their eggs in ...

An annotated cDNA library and microarray for large-scale gene-expression studies in the ant Solenopsis invicta
This could indicate that these gene categories are over- or underrepresented in the fire ant genome relative to the .... To permit functional genomic analysis for the fire ant we produced a cDNA microarray using all 22560 clones ...

Genome complexity and organization in the red imported fire ant Solenopsis invicta Buren.
Melting-temperature analysis showed that the GC content of the fire ant genomic DNA is 34.8%, similar to that of most eukaryotic organisms. The results reveal that the fire ant genome is much larger and more complex than those of a ...
The Royal Genome
"Very little is known about the ant genome," says Keller. But, he adds, ants offer a unique model system for studying aging because the range of life expectancy in ants isn't found elsewhere in nature. The primate equivalent to a ...

Ant chemical shows promise as treatment for Alzheimer's
The pheromone trail laid down by an Aphaenogaster rudis ant, to help the ant and its recruited nest mates find their way back to prey they plan to kill, contains a chemical now undergoing clinical trials as a possible Alzheimer's ...

Exploitation of an ant chemical alarm signal by the zodariid spider Habronestes bradleyi Walckenaer
Intraspecific signals are vulnerable to exploitation by predators that are not the targets of the signal. This cost has been documented for several acoustic, visual and chemical signals, but not for chemical alarm pheromones. We reveal a novel form of exploitation of an ant ...
