Evolutionary Ecology of Freshwater Animals: Concepts and ...
Evolution of iteroparity and indeterminate growth In a seminal paper, Cole (1954)
suggested that for a semelparous species, the gain in the rate of increase from
switching to iteroparity is equal to increasing the average semelparous clutch ...

Ecology: Principles and Applications
Theoretical ecologists have tried to predict which species should be semelparous
and which iteroparous. Unfortunately, as is often the case. it is easier to produce
such theoretical models than to obtain the data to test them. One study which ...

Introduction to Plant Population Biology
One might expect that the huge crops of seed produced by semelparous
perennials would compete with one another as seedlings and that this might alter
the shape of the fecundity curve towards iteroparity (Young & Augspurger 1991),
but ...

The Princeton Guide to Ecology
Now let us set FA to 0.9 (90% of adults survive a year) and BI and BS to 0.5 and
2.5, respectively (the semelparous organism produces on average two more
offspring per year than does the iteroparous organism). If D1⁄4 0, all years are the
...

The Biology of Moral Systems
the semelparous organism will tend to a greater degree to maintain its vigor, or
prevent any senescence, until reproduction actually occurs. This is so because
the iteroparous organism undergoes a gradual reduction in the proportion of its ...

Life History Evolution in Plants
Botanists often use the terms "monocarpic" and "polycarpic" rather than "
semelparous" and "iteroparous", respectively (Harper 1977, Willson 1983). In
modular plants it is not easy to define what -"breeding once" and "breeding
repeatedly" ...

American Shad (Alosa sapidissima), most populations and species of Pacific
Salmon (Oncorhynchus spp., excluding nonmigratory Cutthroat and Rainbow
trout), ...

Evolutionary Biology of Aging
The great exception to the general rarity of aging in the wild is the dramatic
deterioration exhibited by semelparous organisms after their single bout of
reproduction. (Semelparous refers to organisms that reproduce only once during
their ...
