Abstract:
Easy maintenance, controlled mating and short generation time make Cardiocondyla obscurior an interesting model for social insect aging research. Using this ant we have begun to study the proximate genomic relationship between mating and aging. Although mating in general has a positive effect and results in fertile queens with long life but drastically reduced metabolic rates, mating can also dramatically reduce queen fitness. Here we review a decade of research on factors affecting queen aging rate and contrast these findings with studies on honeybees and solitary aging models. We conclude by giving a brief outlook of what is to be expected from this model in coming years.

Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
