In order to understand the evolution of complex
societies, researchers are sequencing the genomes of social insects,
including several species of ants. A team, led by Arizona State
University organismal and systems biology professor Juergen Gadau,
sequenced one of the genomes and set out to decipher which genes might
be responsible for defining which ants work and which ants reproduce in a
red harvester ant colony. Find out more in this news release.

Yellow jackets are wasps, and though they seem
eager to inflict pain, they do have some important redeeming qualities.
They kill harmful garden pests and are among the most social insects on
the planet, along with their stinging cousins, the ants and the social
bees. Find out more in this Science Nation video.

The Division of Environmental Biology (DEB) of
the Biological Sciences Directorate supports fundamental research on
populations, species, communities and ecosystems. Scientific emphases
range across many evolutionary and ecological patterns and processes at
all spatial and temporal scales.
In Joshua King’s lab, researchers study
natural history, community assembly and species invasions at multiple
scales in natural and human-altered landscapes. The overarching themes
of the research program are to understand how insects impact ecosystem
functions and the mechanisms that drive species invasions associated
with land-use changes.
Walter R. Tschinkel is the Robert O. Lawton
Distinguished Research Professor of Biological Science at Florida State
University. He is one of the leading entomologists and myrmecologists (a
branch of entomology that focuses on ants) studying the behavior of
ants and the structure of their colonies.
A recent study found that genes involved in
creating different sexes, life stages and castes of fire ants and
honeybees evolved more rapidly than genes not involved in these
processes.
