Any useful evolutionary theory of senescence must be able to explain variation within and among natural populations and species. This requires a careful characterization of age‐specific mortality rates in nature as well as the intrinsic and extrinsic factors that influence these rates. We perform this task for two populations of semelparous Pacific salmon. During the breeding season, estimated daily mortality rates increased from 0 to 0.2–0.5 (depending on the year) over the course of several… 
Predation by Bears Drives Senescence in Natural Populations of Salmon
TLDR
It is found that the degree of condition dependence in extrinsic mortality was very important in driving senescence: populations where bears selectively killed fish showing advancedsenescence were those that senesced least rapidly.
Does variation in the intensity and duration of predation drive evolutionary changes in senescence?
TLDR
The lack of divergence in ageing contradicts the prediction that elevated mortality rates drive evolutionary shifts in ageing and is better explained by considering the predictions of theoretical frameworks that incorporate feedbacks associated with increased mortality such as density- and condition-dependent processes.
Aging in sexual and obligately asexual clones of Daphnia from temporary ponds.
TLDR
It is concluded that divergent selection between habitats remains the best explanation for differences in aging between Daphnia species.
Micro-geographic shift between negligible and actuarial senescence in a wild snake.
TLDR
Results demonstrate that micro-geographic environmental variation can generate qualitative shifts in actuarial senescence patterns, and highlights that taking into account the within-species plasticity of age-dependent trajectories could prove useful in better understanding what determines the evolution of life-history age trajectories.
Temporal changes in blood variables during final maturation and senescence in male sockeye salmon Oncorhynchus nerka: reduced osmoregulatory ability can predict mortality.
TLDR
That major plasma ion levels started to decline 2-10 days before fish became moribund, and before other stress, metabolic or reproductive hormone variables started to change, suggests that a dysfunctional osmoregulatory system may initiate rapid senescence and influence other physiological changes which occur as O. nerka die on spawning grounds.
Senescence in natural populations of animals
TLDR
There is no reason why senescence cannot evolve to be manifest within the life expectancies of wild organisms under antagonistic pleiotropy or disposable soma explanations, and the recent emergence of long-term field studies presents irrefutable evidence thatsenescence is commonly detected in nature.
Age is not just a number—Mathematical model suggests senescence affects how fish populations respond to different fishing regimes
TLDR
The simulation results showed that the presence or absence of senescence affected how the population responded to the selection regime, and the change in biomass and number of fish in response to different fishery size‐selection patterns depended on the presence ofSenescence.
Size delays female senescence in a medium sized marsupial: The effects of maternal traits on annual fecundity in the northern brown bandicoot (Isoodon macrourus)
TLDR
Results provided support for the effects of senescence on annual fecundity in females, and highlighted the difficulty of measuring reproductive costs and the importance of understanding the combined effects of specific characteristics of an individual when interpreting reproductive strategies in iteroparous organisms.
Thermal exposure of adult Chinook salmon and steelhead: Diverse behavioral strategies in a large and warming river system
TLDR
This study paired radiotelemetry with archival temperature loggers to construct continuous, spatially-explicit thermal histories for 212 adult Chinook salmon and 200 adult steelhead migrating through 470 kilometers of the Columbia and Snake rivers en route to spawning sites in Idaho, Oregon, and Washington.

Comparative Studies of Senescence in Natural Populations of Guppies
TLDR
It is found that females from a natural low‐predation population have delayed senescence compared with the recently established population and hence that the differences among localities insenescence conform to theoretical predictions.
Altitudinal variation for senescence in Melanoplus grasshoppers
TLDR
It is suggested that high-elevation populations have evolved accelerated senescence as a direct or an indirect result of selection on reproductive schedules, which are potentially truncated by severe winter conditions at the elevated sites.
NATURAL GENETIC VARIATION OF LIFE SPAN, REPRODUCTION, AND JUVENILE GROWTH IN DAPHNIA
TLDR
Test the theory of senescence with natural populations of the Daphnia pulex‐pulicaria species complex, a group of freshwater zooplankton that spans an environmental gradient of habitat permanence, and observes negative genetic correlations between r and indices of life‐history timing, suggesting trade‐offs between early‐ and late‐life performance.
Adaptive variation in senescence: reproductive lifespan in a wild salmon population
TLDR
It is shown that early breeders (but not late breeders) are under strong selection for a long reproductive lifespan (RLS), which facilitates defence of their nests against disturbance by later females.
Effect of extrinsic mortality on the evolution of senescence in guppies
TLDR
It is reported here that guppies derived from natural populations do not have an earlier onset of senescence with respect to either mortality or reproduction but do withrespect to swimming performance, which assesses neuromuscular function.
The evolution of senescence in fish
The interaction between reproductive lifespan and protandry in seasonal breeders
TLDR
The model predicts that protandry and maximum reproductive lifespans should increase in environments characterized by high survival and by a low competitive cost of maintaining the somatic machinery necessary for survival, and shows that pronounced seasonal declines in reproductive lifespan are likely part of a male mating strategy to maximize mating opportunities.
Body size, arrival date, and reproductive success of pink salmon, Oncorhynchus gorbuscha
TLDR
Investigation in a naturally reproducing population of pink salmon in southeast Alaska indicated that both body size and arrival date affect potential reproductive success but complex interactions between these factors and predation are also very important.
Condition dependence and adaptation-by-time: breeding date
TLDR
Examination of a population of sockeye salmon found that adaptation-by-time may play an important role in life history evolution within some species, particularly those with breeding systems characterised by semelparity, capital breeding, and heritable breeding times.
PLEIOTROPY, NATURAL SELECTION, AND THE EVOLUTION OF SENESCENCE
TLDR
Natural selection will frequently maximize vigor in youth at the expense of vigor later on and thereby produce a declining vigor (senescence) during adult life, which explains much of what is known of phylogenetic variation in rates of senescence.
