This book is the first comprehensive treatment of sex allocation from the standpoint of modern evolutionary theory. It shows how the determination of sex ratio, resource allocation to sperm versus egg within simultaneous hermaphroditism, and the evolution of sex reversal can he explained as examples of a single process. The genetical theory, developed mostly with graphical arguments, also specifies when hermaphroditism and dioecy are themselves evolutionary stable. The work balances theory with… 
Sex allocation in animals
The theory of sex allocation is treated as an example of the study of adaptation, the assumptions are analyzed, the structure of the theory ofsex ratio is displayed, and some generalizations of this theory are considered.
Tests of Sex Allocation Theory in Simultaneously Hermaphroditic Animals

Over 50 empirical studies, which have aimed at evaluating sex allocation theory in a diversity of simultaneous hermaphrodites spanning nine animal phyla, are summarized and the main questions that need to be addressed are identified and point to promising avenues for future research.
The application of sex allocation theory to heterostylous plants
Sex allocation theory predicts the evolutionarily stable sex ratio in dioecious species, the allocation of resources to male vs. female function in simultaneous hermaphrodites, and the time and order
Evolution and ecology of sex allocation
Lab experiments using the rodent malaria and field studies provide the first set of comprehensive data concerning the field sex ratios of 2 species of sea turtle nesting in the Mediterranean and an additional assessment of using indirect methods to measure sex ratios in the field, and whether the assumptions of sex allocation theory are appropriate to malaria parasites.
Experimental tests of sex allocation theory in a simultaneous hermaphrodite using phenotypic engineering
This thesis provides experimental evidence for two fundamental aspects of sex allocation theory, namely a saturating male fitness gain curve and the existence of a trade-off between male and female allocation in a copulating simultaneous hermaphrodite.
Sex allocation in functionally hermaphroditic plants: A review and critique
The need for better measures of allocation as well as better accounting of the many other possible factors that may determine individual (and population) allocation ratios is emphasized.

This work contrasts sex allocation theory to a different, emerging viewpoint, pollen presentation theory (PPT), which attempts to address variation in reproductive success by measuring and modeling the quantitative fates of pollen grains, and discusses recent work aimed at testing some key assumptions and predictions by functional and comparative studies in the genus Penstemon.
Models of sex ratio evolution
The models used in this work are of two general kinds: expected-future-fitness or tracer-gene models that ask how a given sex allocation will affect the future frequencies of neutral genes carried by the allocating parent, and explicit population-genetic models that consider the dynamics of alleles that determine alternative parental sex allocation phenotypes.
Recent studies of avian sex ratios
The theory and data required to predict sex allocation patterns (let alone sex ratio patterns) in vertebrates are complex and hard to obtain and the investigation of the role of constraint vs. adaptation in evolution is investigated.
Adaptive sex allocation in birds: the complexities of linking theory and practice.

It is argued that standard sex allocation models, very helpful in understanding sex allocation of invertebrates, do not sufficiently take the complexities of bird life histories and physiology into account and that experimental field and laboratory studies on sex allocation in birds are scarce.
