Abstract. Organisms cannot maximize all life functions and therefore must allocate resources to maximize reproductive fitness such that they produce the highest number of surviving offspring. The object of the experiment was to evaluate variation of fruit morphology to determine how Opuntia littoralis optimizes reproductive investment. The experiment focused on fruit volume, sugar concentration, number of seeds and average seed mass on two different aspects (polar-facing and equatorial-facing… 

Preliminary Report: Effects of black mustard allelopathy on the fitness and life history strategies of buffalo gourd in southern California

TLDR
It was found that C. foetidissima growing in close proximity to B. nigra had smaller fruit volume, a lower number of seeds per fruit, lower dry seed weight, and a higher number of Seeds per cubic centimeter, than C. cucurbita that grew outside of the allelopathic range of B. Nigra.

TLDR
This paper is an attempt to show that this and other existing hypotheses when taken singly are inadequate in some respect to account for all the data, that each holds for some particular set of con- ditions, and that each is but a part of the complete explanation.

Some Life-History Consequences of Modular Construction in Plants

TLDR
The nature and life-history consequences of modular construction in plants are discussed with particular reference to growth, reproduction and survival, and there are fundamental differences between the reproductive schedules of plants with a single shoot module and those with many shoot modules.

The Demographic Cost of Reproduction and Its Consequences in Balsam Fir (Abies balsamea)

TLDR
This article used serial correlation and a permutation test to detect growth costs of reproduction and show how these translate into demographic costs when relative tree size (and therefore growth) is critical to survival.
