Overview
Animal aging is the progressive set of biological changes that occur in animals over their lifespan, leading to a gradual decline in physiological function and resilience. It involves changes at the molecular, cellular, and organ levels, including altered metabolism, reduced tissue repair, and increasing susceptibility to disease. Patterns of aging vary widely across species, with differences in lifespan, the pace of decline, and the visible signs of senescence such as reduced activity, changes in coat or appearance, and declining reproductive capacity. The comparative study of these patterns across animals helps researchers understand the cellular mechanisms and evolutionary basis of aging and why different species age at very different rates. As a journal devoted to Zoological Research, this title publishes peer-reviewed, open-access work on animal biology, including physiology, development, and life history across diverse species. This page gathers literature relevant to animal aging, supporting readers seeking primary research on how animals change with age, the biological processes that drive senescence, and the comparative differences in aging observed across the animal kingdom.
