Balancing Breeding for Growth and Fecundity in Radiata Pine (Pinus radiata D. Don) Breeding Programme

open access: yesEvolutionary Applications, 2021
Tree breeding has focused on increasing stem volume growth with a cost to fecundity. However, fecundity is important in maintaining the fitness in natural stands and facilitating cross‐pollination to advance breeding populations.

Macroevolutionary Trade-Offs and Trends in Life History Traits of Cephalopods Through a Comparative Phylogenetic Approach

open access: yesFrontiers in Marine Science, 2021
One of the major mechanisms responsible for the animals’ fitness dynamics is fecundity. Fecundity as a trait does not evolve independently, and rather interacts with other traits such as body and egg size.

The end of fertility: age, fecundity and fecundability in women [PDF]

open access: yesJournal of Biosocial Science, 1994
SummaryOnset of capacity for childbearing in women is dated biologically by menarche, although actual onset may be delayed. The end of childbearing is less understood but recent demographic and biological research on fertility at older ages is clarifying the end of fertility.The demographic view of declining fertility with age is based on age-specific ...

Experimental selection reveals a trade-off between fecundity and lifespan in the coliphage Qß [PDF]

open access: yesOpen Biology, 2013
Understanding virus evolution is key for improving ways to counteract virus-borne diseases. Results from comparative analyses have previously suggested a trade-off between fecundity and lifespan for viruses that infect the bacterium Escherichia coli (i.e.
