Ecosystems of the Deep Oceans
Age distribution of reproductive effort Background In his classic paper linking life-
history traits with population growth, Cole (1954) focused on the demographic
advantages and disadvantages of one-time reproduction (semelparity) and ...

Longevity, Senescence, and the Genome
Of particular interest to the genetic basis for semelparity are phenotypes of
conditional semelparity. A striking example is that of the American shad Alosa
sapidissima; shad are clupeiforms, a different order than salmon (Table 2.3). The
most ...

The Behavior and Ecology of Pacific Salmon and Trout
Semelparity Not only do salmon migrate to sea and come back to their natal
stream to spawn but death inevitably follows reproduction in many Pacific salmon
species. This life-history pattern, termed semelparity, transfers millions of
kilograms ...

Plant Reproductive Ecology : Patterns and Strategies: ...
In theory, semelparity is favored by conditions under which the probability of
reproductive success at a given time is high, and iteroparity is favored when the
chance of reproductive success is low." Thus, the semelparous organism may be
at ...

Mammalogy: Adaptation, Diversity, Ecology
SEMELPARITY. VERSUS. ITEROPARITY. As we pointed out in chapter 22, some
organisms, such as annual plants, insects, and the Pacific salmon, reproduce
only once during their entire lifetimes. These “big bang” breeders are called ...

Physiological Ecology of Pacific Salmon
The property of semelparity remains somewhat perplexing. What are its
advantages? Why does it persist in all the species? How did it evolve? The last of
these questions is perhaps the hardest, and the second might be recast as "How
can ...

Semelparity and Iteroparity
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Semelparity and Iteroparity refer to the reproductive strategy of an organism.

Encyclopedia of Ecology, Five-Volume Set: Online version
Early work predicted that greater temporal variation in adult survival relative to
juvenile survival favored the evolution of semelparity, although more recently it
has been demonstrated that this also depends on the age structure of the
population ...
9
The Other Insect Societies
Tallamy and Brown's idea might be termed the semelparity hypothesis: semel-
parous rather than iteroparous insects are more likely to evolve parental (in
particular maternal) care since limited possibilities of future reproduction lowers
the ...

Evolution Illuminated : Salmon and Their Relatives: Salmon ...
Further reflection, however, suggests that such considerations do not explain the
origin of semelparity in this group. In the first place, anadromous rainbow trout or
"steelhead" (O. mykiss), cohabit the same river systems and, in some cases, ...
