Symposium on Metabolism, Life History and Aging to be held at the SICB 2010 Conference (January 3 - 10, Seattle, WA)

实验室模式生物，如实验室大鼠，已经证明了新陈代谢和衰老之间的明确联系，众所周知，生殖和衰老的进化可以由代谢因素驱动。然而，无论是从理论上还是从机械的角度来看，关于采取特定的生活史策略如何影响面临不同能量需求的人群的衰老和寿命，鲜为人知。例如，在恶劣的气候条件下，将精力投入到早期成长和成熟中，从而获得短暂的寿命，是不是更好？这次研讨会将汇集一个国际生物老年学家小组，他们在不同生物组织(分子到种群)的不同水平上研究各种脊椎动物和无脊椎动物生物，以讨论和综合生活史、进化及其代谢后果的研究。研讨会的参与者包括来自三个不同国家、处于不同职业阶段的男性和女性。预计这些从不同角度研究衰老的科学家的互动将促进未来的合作。

Laboratory model organisms, such as the lab rat, have demonstrated a clear link between metabolism and aging, and it is well known that the evolution of reproduction and aging can be driven by metabolic factors. Nevertheless, there is little known, from either a theoretical or a mechanistic viewpoint, about how the adoption of specific life history strategies can shape aging and life span in populations facing different energetic demands. For example, in harsh climates, is it better to invest energy into early growth and maturation and, as a consequence, have a short life-span? This symposium will bring together an international group of biogerontologists who work on a variety of vertebrate and invertebrate organisms at different levels of biological organization (molecules to populations) in order to discuss and synthesize studies of life history evolution and its metabolic consequences. The symposium participants include men and women from three different countries and who are at different career stages. It is anticipated that the interaction of these scientists, who study aging from different perspectives, will foster future collaborations.
