    Exp Gerontol 36:687-94. 2001
    ..The results show that senescence in the natural environment is caused by an increased vulnerability of older individuals to environmental stress. Under the protected environmental conditions of the greenhouse senescence was negligible...

    ..Moreover, this analysis suggests that increasing size after reproductive maturity may allow this plant species to escape from demographic senescence...

    Ecology 90:1427-33. 2009
    ..Neither size nor quantity of reproduction could explain this variation in mortality across cohorts. These results demonstrate demographic senescence in a natural population of plants...

    Richard P Shefferson
    Department of Biology, University of Virginia, Charlottesville, Virginia 22904, USA

    ..Such environmental influences, particularly on early life size, may result in small but important indirect effects on fitness...

    Oecologia 136:141-7. 2003
    ..This pattern did not continue into 3-year-old plants. A possible explanation for this is that selective mortality allows only generally robust plants, and consequently the most resistant plants, to survive to the oldest ages...

    ..More generally, our models contribute to understanding of the evolutionary and demographic forces that mold the age-trajectories of mortality, fertility and growth...
