Use of model organisms in aging research is problematic because our ability to extrapolate
across the tree of life is not clear. On one hand, there are conserved pathways that regulate …

An increasing number of studies have shown that senescence, the functional decline in traits
and increased risk of mortality with increasing age, occurs in organisms in wild populations …

Among‐individual variation in vital rates, such as mortality and birth rates, exists in nearly all
populations. Recent studies suggest that this individual heterogeneity produces substantial …

Plants hold all records in longevity. Their aging is a complex process. In the presented
review, we analyzed published data on various aspects of plant aging with focus on any …

Age‐dependence of the demographic rates survival, fecundity and individual growth is a
fundamental aspect of population biological theory. Knowledge about plant ageing can also …

Demographic rates in plants are usually assumed to be more stage or size dependent than
age dependent, and aging is therefore not considered in demographic models. However …

Trade‐offs between reproduction, growth and survival arise from limited resource availability
in plants. Environmental stress is expected to exacerbate these negative correlations, but no …

Whole‐plant senescence, defined as a decrease in individual fitness as an organism grows
older, has often been assumed to not occur in plants; however, it has now been detected in …

Comparative studies have demonstrated extensive variation in age trajectories of mortality
and fecundity, both within and among species, with many taxa exhibiting a general pattern of …

Relative to mammals and birds, little is known about the mortality trajectories of perennial
plants, as there are few long-term demographic studies following multiple yearly cohorts …
