TL;DR: This chapter reviews evidence for rapid evolutionary diversification of EFI genes, correlated evolution of sex-specific EFI traits, and the relationship between genetic compatibility, male–female interactions, and patterns of sperm precedence.
Abstract: Publisher Summary The mechanisms of sexual reproduction are expected to be complex and evolutionarily dynamic in internally fertilizing species, where numerous biochemical, physiological, morphological, and behavioral mechanisms mediate insemination, sperm migration, sperm storage, the maintenance of sperm viability, and sperm modification, all of which must be properly executed before fertilization can begin. This situation provides the opportunity for postcopulatory sexual selection, which is predicted to further enhance complexity and diversification in genes contributing to differential male fertilization success and female control over paternity. It is becoming increasingly clear that sperm and ejaculate constituents evolve in response to selection pressures imposed by the female reproductive tract. Ejaculate–female interactions (EFIs) can determine whether or not a reproductive attempt is successful and can influence the outcome of sperm competition within populations. Evolutionary diversification of EFIs may further determine the extent of reproductive isolation and gene introgression between closely related species. This chapter aims to illustrate the pervasiveness of EFIs by discussing different types and what is known about their underlying mechanisms, and it considers the evolutionary significance of EFIs. Furthermore the chapter reviews evidence for rapid evolutionary diversification of EFI genes, correlated evolution of sex-specific EFI traits, and the relationship between genetic compatibility, male–female interactions, and patterns of sperm precedence.

TL;DR: It is suggested that while females are facultatively polyandrous, copula duration, sperm transfer and male accessory gland secretions act in succession to inhibit female receptivity.

TL;DR: The internal female genitalia are diverse in Sepsidae and diagnostic for all species, and fast-evolving structures like the ventral receptacle and dorsal sclerite are likely involved in post-copulatory sexual selection.
Abstract: The species-specificity of male genitalia has been well documented in many insect groups and sexual selection has been proposed as the evolutionary force driving the often rapid, morphological divergence. The internal female genitalia, in sharp contrast, remain poorly studied. Here, we present the first comparative study of the internal reproductive system of Sepsidae. We test the species-specificity of the female genitalia by comparing recently diverged sister taxa. We also compare the rate of change in female morphological characters with the rate of fast-evolving, molecular and behavioral characters. We describe the ectodermal parts of the female reproductive tract for 41 species representing 21 of the 37 described genera and define 19 morphological characters with discontinuous variation found in eight structures that are part of the reproductive tract. Using a well-resolved molecular phylogeny based on 10 genes, we reconstruct the evolution of these characters across the family [120 steps; Consistency Index (CI): 0.41]. Two structures, in particular, evolve faster than the rest. The first is the ventral receptacle, which is a secondary sperm storage organ. It accounts for more than half of all the evolutionary changes observed (7 characters; 61 steps; CI: 0.46). It is morphologically diverse across genera, can be bi-lobed or multi-chambered (up to 80 chambers), and is strongly sclerotized in one clade. The second structure is the dorsal sclerite, which is present in all sepsids except Orygma luctuosum and Ortalischema albitarse. It is associated with the opening of the spermathecal ducts and is often distinct even among sister species (4 characters; 16 steps; CI: 0.56). We find the internal female genitalia are diverse in Sepsidae and diagnostic for all species. In particular, fast-evolving structures like the ventral receptacle and dorsal sclerite are likely involved in post-copulatory sexual selection. In comparison to behavioral and molecular data, the female structures are evolving 2/3 as fast as the non-constant third positions of the COI barcoding gene. They display less convergent evolution in characters (CI = 0.54) than the third positions or sepsid mating behavior (CI COI = 0.36; CIBEHAV = 0.45).

TL;DR: It is suggested that the use of both organs by females results in sperm economy, which adaptively prolongs the intervals between copulations, and both the spermathecae and the fertilization chamber are active sperm storage organs.

TL;DR: A growing body of evidence has begun to reveal flaws in the traditional assumption of female passivity and lack of discrimination after copulation has begun as discussed by the authors, and evidence from various fields indicates that such selectivity by females may be the norm rather than the exception.
Abstract: A growing body of evidence has begun to reveal flaws in the traditional assumption of female passivity and lack of discrimination after copulation has begun. William Eberhard has compiled an impressive array of research on the ability of females to shape the outcome of mating. He describes studies of many different cryptic mechanisms by which a female can accept a male for copulation but nevertheless reject him as a father. Evidence from various fields indicates that such selectivity by females may be the norm rather than the exception. Because most post-copulatory competition between males for paternity is played out within the bodies of females, female behaviour, morphology, and physiology probably often influence male success in these contests. Eberhard draws examples from a diversity of organisms, ranging from ctenophores to scorpions, nematodes to frogs, and crickets to humans. Cryptic female choice establishes a new bridge between sexual selection theory and reproductive physiology, in particular the physiological effects of male seminal products on female reproductive processes, such as sperm transport, oviposition, and remating. Eberhard interweaves his review of previous s

Abstract: This text presents the chemical and physical principles of fixation, staining and histochemistry. It assumes a basic level of chemical and biological knowledge, and requires little mathematical skill. The relations of chemical structures and reactions to fixation, tissue processing, staining, enzyme location, immunohistochemistry and other procedures are explained. For this edition the author has updated the text with the latest techniques and developments within the field, whilst retaining the details of the classic techniques still in use.
