Abstract:
Abstract Delayed mating is an effective strategy that can decrease the fecundity of a pest by reducing the time that females have to mate. This disruption does not completely inhibit mating and may lead to multiple matings. The effects of delayed mating with multiple partners on different indexes of mating in female and male Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae) were determined in this study. The delay in mating significantly decreased the number of matings and the mating success of both sexes and the male contribution to reproduction. Compared with the effect on female fecundity, the delayed mating with multiple partners had a greater effect on the male mate contribution to fecundity. The longevity of females and males increased significantly with a 72 h delay in mating. Linear regression analysis showed negative relationships between delayed mating and fecundity and number of matings in both sexes. Thus, delayed mating with multiple partners can disrupt the mating and reproductive potential of S. litura.

Abstract:
Conjugation on agar plates following mating trials can cause transconjugant numbers to be overestimated. Numbers of transconjugants detected after incubating donors and recipients together were compared with those observed when donors and recipients were incubated separately and then mixed immediately prior to plating on selective agar. Mating comparisons were conducted using broth, a soil slurry, and nonsterile soil. Nalidixic acid was added to selective agar plates to investigate its use as an inhibitor of plate mating. The number of transconjugants from broth matings did not significantly differ from the number of transconjugants produced by plate mating on selective media lacking nalidixic acid. Addition of nalidixic acid to selective media reduced the number of transconjugants from broth matings by 10-fold and the number of transconjugants from plate mating after incubation in broth by 100-fold. The number of transconjugants detected from mating experiments in soil slurries was significantly greater than the corresponding plate matings (p = 0.0073). Furthermore, the addition of nalidixic acid to selective agar eliminated all plate matings. In nonsterile soil matings, transconjugants were detected immediately after the inoculation of donors and recipients into soil only when nalidixic acid was absent from the medium. Key words: transconjugants, in situ conjugation, gene exchange in soil, plate matings.

Abstract:
Abstract In socially monogamous species with bi-parental care, males may face a trade-off between providing parental care and pursuing extra-pair matings. The “parenting-mating trade-off” hypothesis predicts that high-quality males—who have greater potential to gain extra-pair matings, for example, larger males usually win the competition for extra-pair mating—should reduce parental care and spend more time looking for extra-pair matings. However, the trade-off between parenting and mating efforts may be complicated by variation in the availability of extra-pair mating opportunities. By using field data of hair-crested drongos (Dicrurus hottentottus), a species exhibiting bi-parental incubation behavior, collected in central China from 2010 to 2017, we tested whether the potential negative relationship between male quality and paternal care was dependent on the number of nearby fertile females. We found that male drongos mainly seek extra-pair matings during the incubation period and high-quality individuals (males with longer tarsi) are more likely to sire extra-pair offspring. In agreement with the “parenting-mating trade-off” hypothesis, high-quality males incubated less by recessing longer between incubation bouts. However, this was only the case when sufficient fertile females nearby for extra-pair mating opportunities. Females compensated for reduced male care, but this was independent of male quality. This suggests that the reduction in care by high-quality males might be a direct response to extra-pair mating opportunities rather than facilitated by differential allocation of females. Our results indicate that individual quality and available mating opportunities may shape the optimal trade-off between parental care and seeking additional matings for males.

Abstract:
We study the evolution of male and female mating strategies and mate choice for female fecundity and male fertilization ability in a system where both sexes can mate with multiple partners, and where there is variation in individual quality (i.e. in the availability of resources individuals can allocate to matings, mate choice and production of gametes). We find that when the cost of mating differs between sexes, the sex with higher cost of mating is reluctant to accept matings and is often also choosy, while the other sex accepts all matings. With equal mating costs, the evolution of mating strategies depends on the strength of female sperm limitation, so that when sperm limitation is strong, males are often reluctant and choosy, whereas females tend to accept available matings. Male reluctance evolves because a male's benefit per mating diminishes rapidly as he mates too often, hence losing out in the process of sperm competition as he spends much of his resources on mating costs rather than ejaculate production. When sperm limitation is weaker, females become more reluctant and males are more eager to mate. The model thus suggests that reversed sex roles are plausible outcomes of polyandry and limited sperm production. Implications for empirical studies of mate choice are discussed.

AbstractThe egg release–mating comparison, heterospecific matings and mating success under two hybridization conditions – (i) mixing one sex per species and (ii) mixing both sexes from each species – were investigated to determine whether silver bream Blicca bjoerkna and common bream Abramis brama can hybridize in nature.The results revealed that non-matings in hybridization experiments of silver bream females × common bream males can be explained by territorial and aggressiveness activities observed in common bream. In common bream females × silver bream males, heterospecific matings were observed but their numbers were significantly lower than the spawning numbers, and in this experiment, a female mated with one to four heterospecific males. In mixing both sexes from both species, similar spawning – mating numbers were observed but heterospecific matings accounted for only 27% of the total matings, with 24% accounting for heterospecific matings between common bream females and silver bream males, directly or by opportunism. Mating success was characterized by the occurrence of fertilized eggs after matings.Natural hybridization occurred preferentially between common bream females and silver bream males.

Abstract:
Comparing the reproductive output of intra- and inter-population matings is the most common way to assess whether post-mating reproductive isolation is caused by genetic incompatibilities. Such genetic incompatibility can however, only assume that the quantity of the post-mating signals involved does not differ between intra- and inter-population matings. This assumption may not be true because sexual selection predicts reduced mating effort towards low-quality mates and in many circumstances, allopatric partners are low-quality mates. Post-mating efforts may, therefore, be reduced in inter- compared to intra-population matings. Here, I test this crucial assumption by studying variation in one post-mating trait, sperm number, in crosses of two parapatric grasshopper populations. In both populations, males transferred fewer sperm to allopatric than sympatric females. If such plasticity with respect to population is common in other post-mating traits, differences between inter- and intra-population crosses may be more frequently caused by differences in sperm number rather than gamete incompatibility. Additionally, I found that sperm numbers declined less rapidly in the female storage organ of allopatric than sympatric females but its rate differed markedly between populations. This is discussed with respect to female adaptations to male traits.

Abstract:
Abstract Random mating is the null model central to population genetics. One assumption behind random mating is that individuals mate an infinite number of times. This is obviously unrealistic. Here we show that when each female mates a finite number of times, the effective size of the population is substantially decreased.

Abstract:
AbstractStochastic simulation is used to compare different systems of mating to reduce rates of inbreeding in selection programmes with phenotypic or animal model best linear unbiased prediction (BLUP) evaluation. Compensatory mating (the mating between individuals from the largest selected families to individuals from the smallest) turns out to be proportionately about 0-30 more effective than minimum coancestry matings for situations with low rates of inbreeding, such as phenotypic selection or high population size, although the advantage is less apparent if common environmental effects are important. A modification of this system of mating is proposed which can be applied for overlapping generations, and this is shown to reduce rates of inbreeding proportionately by about 0-50 more than for discrete generations. Under high inbreeding, however, such as for BLUP selection and small population size, minimum coancestry matings, or even avoidance of sib matings are more effective. A procedure combining compensatory and minimum coancestry matings is also simulated and gives the largest reductions in the rate of inbreeding. The effects of these and other systems of mating on the rate of inbreeding are shown to occur through a reduction in the cumulative effect of selection and a deviation from Hardy-Weinberg proportions.

Abstract:
AbstractA chromatic mutation, dark body (mutants with a darker body than wild individuals), allowed us to test the effectiveness of the second mating in the bisexual species Trichogramma turkestanica Meyer, and of the first mating in the thelytokous species T. cordubensis Vargas and Cabello. Second mating in T. turkestanica was mostly efficient (i.e. followed by fertilization). Nevertheless, the latency before the second mating was longer as the time between second and first matings increased. The utilization of the spermatozoa from the second mating increased as the stock of spermatozoa from the first mating decreased. A long time in the presence of a male was necessary to obtain mating of the thelytokous females of T. cordubensis. Such fertilized females produced a low percentage (28%) of daughters from bisexual reproduction.

Abstract:
Assortative mating has been documented within the Gasterosteus aculeatus complex. The outcome of laboratory mating trials between individuals from allopatric populations of the blackspotted stickleback, Gasterosteus wheatlandi, is reported. A total of 70 intra- and inter-population mating trials between individuals from Massachusetts and Connecticut were conducted between 1984 and 1987. The results showed differences in the proportion of successful matings, measured as nests constructed, eggs deposited, and young produced. Although intrapopulation mating trials yielded the greatest proportion of nests, eggs, and young, mating did not proceed beyond nest construction between males from Massachusetts population and females from Connecticut population. These results suggest asymmetric reproductive isolation between this mating combination, as all other mating types produced offspring. Further research is necessary to resolve questions concerning differences in motivational states and reproductive behavioral cues.

Abstract:
Mating Call is a memoir set in the Pacific Northwest during the 1990s, in what Spin Magazine calls "Seattle's Golden Age." The story begins with my arrival in the West and a self-inflicted broken heart, a relationship I had severed due to "missing pieces." The quest is to find these pieces, and throughout the search the memoir analyzes love and relationships for Generation X. The quest takes seven years, during which the narrative explores Seattle's breweries and bedrooms, and the Northwest's rainforests and volcanoes, all the while investigating interpersonal chemistry, sex, and friendship. For all the searching, the missing pieces are actually discovered by accident, when happenstance deals my heart a second blow; the quest is over, and I return East.

Abstract:
In N. crassa, a specialized hypha, the trichogyne, grows out chemotropically from the ascogonium (female cell) towards a sex pheromone releasing male cell which is commonly a macroconidium of opposite mating type. Following macroconidium-trichogyne fusion, the male and female nuclei were formed to be arrested in nuclear division. The female nuclei became immobilized, rounded up and clumped together whilst all of the male nuclei from the macroconidium moved unidirectionally and sequentially towards the ascogonium with an ‘inchworm-like’, repeated elongation and condensation pattern of movement. Dynein, kinesins and myosins played a role in regulating perithecial formation and the behaviour of male and female nuclei during mating. The dynein subunits DYN2, DLC, DIC and DYN27, the kinesins NKIN2 and KAR3, and the myosin MYO2 encoded by the female influenced male nuclear behaviour whilst the dynein subunit RO-3, the kinesin KIP2 and the myosins MYO1 and MYO2 encoded by male influenced female nuclear behaviour. These results showed that motor proteins derived from the male and female cooperate to regulate the movement of male nuclei and that male-female nuclear recognition occurs immediately following macroconidium-trichogyne fusion. Disruption of microtubule and actin polymerization, and inhibition of myosin activity, inhibited perithecial development and perturbed male nuclear behaviour during mating. A new type of hypha produced by conidia, the conidial sex tube (CST), was discovered. It was found to be included by sex pheromone from the opposite mating type and to be regulated by red, green and blue light.

Abstract:
Die Forschung an der Hefe Saccharomyces cerevisiae – auch als Bäckerhefe bekannt – hat sich für die biologische Grundlagenforschung als unentbehrlich erwiesen und führte zu wichtigen Erkenntnissen in der Erforschung von Krankheiten wie Krebs. Am Beispiel der Paarung von Hefezellen werden in dieser Arbeit wesentliche Aspekte der eukaryotischen Zellbiologie untersucht. In der Haplophase des Lebenszyklus der Hefe, treten haploide Zellen als Paarungstyp MATa oder MATα auf. Diese Paarungstypen kommunizieren über Pheromone, die in ein extrazelluläres Medium abgesondert werden und von Zelloberflächenrezeptoren des komplementären Paarungstyps erkannt werden. Hefezellen wachsen in die Richtung eines möglichen Paarungspartners, da sie sich nicht aktiv bewegen können. Die Auswertung von empirischen Daten aus der Fluoreszenzmikroskopie und Rasterkraftmikroskopie (AFM) mit mathematischen Modellen ermöglichte die Rekonstruktion wesentlicher Prozesse der Hefepaarung: (i) Interzelluläre Kommunikation über die Sezernierung und Rezeption von Pheromonen, (ii) Aufbau der Zellpolarität als Reaktion auf die Pheromonantwort, (iii) Induktion und Mechanik der Zellformänderung. Folgende Modelle wurden dazu entwickelt: (i) Die interzelluläre Kommunikation wurde unter Verwendung von zellulären Automaten mit Hilfe von Reaktions-Diffusions (RD) Gleichungen modelliert. Das Modell zeigte, dass die gegenseitige Stimulierung und erhöhte Pheromonabsonderung zu einer verbesserten Abstimmung in der Paarung in der Zellpopulation führt. (ii) Ein Turing- und ein Phasenseparations- Mechanismus wurden als Modelle zum Aufbau der Zellpolarität verwendet. Volumen-Oberflächen gekoppelte RD Gleichungen wurden analytisch und numerisch mit der Finite-Elemente-Methode (FEM) untersucht. (iii) Die Zellwandveränderung wurde mit klassischer Kontinuumsmechanik und der FEM Methode modelliert. Dies ermöglichte eine Beschreibung der reversiblen elastischen und der irreversiblen plastischen Verformungen der Zellwand.
Research on the yeast Saccharomyces cerevisiae – also known as baker’s yeast – has been essential not only for fostering basic biological knowledge but even more so for contributing towards understanding diseases such as cancer. In this thesis, general biological phenomena occurring in eukaryotic cells are investigated, exemplified by the mating process of yeast. In the haploid phase of their life cycle, yeast cells occur as mating type MATa or MATα, both of which communicate via pheromones that are secreted in an extracellular medium and can be sensed by cell-surface receptors of the complementary mating type. In order to mate, yeast cells grow towards a potential mating partner, since they are not able to actively move. Mathematical models on the basis of fluorescence and atomic force microscopy (AFM) data were developed. The key aspects of the yeast mating process that I examined were (i) intercellular communication of cells via pheromones, (ii) the initial symmetry break and implementation of cell polarity, and (iii) subsequent morphogenetic changes. The methods used and findings were as follows: (i) Pheromone secretion and sensing motifs were modelled using cellular automata models based on reaction-diffusion (RD) equations. My models show that mutual stimulation and increased pheromone secretion between cells improves mating efficiency in cell populations. (ii) To explain yeast mating decisions, two possible model types for cell polarity were tested: a Turing-type and a phase-separation mechanism. Bulk-surface RD equations were investigated analytically and numerically using the finite element method (FEM). Typical cell shapes were reconstructed in 2D and 3D. (iii) The cell wall was modelled using classical continuum mechanics that allows for reversible elastic and irreversible plastic cell wall deformation. Mathematical modelling demonstrated that all three processes investigated are precisely orchestrated and interlocked during yeast mating.

Abstract:
A recent line of research grounded in evolutionary theory has shown that exposure to women's fertility cues affects men's mating cognition and behavior. This area of research has not yet been examined in relation to alcohol. As alcohol has also been shown to facilitate the formation of sexual connections for males, establishing the intersection between these two lines of research seems necessary to understand the impetus behind human behavior. Ninety-eight male participants were primed with either the scent of a fertile woman or the scent of nonfertile woman and then completed measures assessing their level of attraction to pictures of women, beer consumption, approach behavior, and alcohol expectancies. Results of the study indicated that males' mating behaviors are affected by women's ovulatory cues, as men exposed to an ovulation prime drank significantly more and exhibited significantly more approach behavior than men exposed to a control prime. Furthermore, an interaction was found between sexual enhancement expectancies and prime condition on beer consumption, which indicated that there was no effect for sexual enhancement expectancies for those in the control prime condition, but for those in the ovulation prime condition, increased drinking was associated with higher sexual facilitation expectancies. These findings were consistent with previous research and support evolutionary theories of mating behavior while taking an integrative approach in trying to explain factors behind human behavior.

Abstract:
Abstract This paper presents an algorithm for generating tolerance chains from the mating relations between components of assemblies. The algorithm is developed upon a feature-based assembly modeling strategy that represents each component in close relation to its mating features, dimensions and tolerances. The mating relations within an assembly are described by a mating graph. Tolerance chains together with their dimensions and tolerances are generated automatically by searching through a mating graph for matching mating features. A prototype program package based on the presented algorithm has been developed, and several examples of various complexity have been tested with success.

Abstract:
A hybrid method combining a genetic algorithms based containment algorithm with a complex mating algorithm is presented. The approach uses mating between a pair of objects as means to accelerate the packaging process. In this study, mating between two objects has been defined as positioning one object relative to others by merging common features that are assigned through mating conditions between them. A constrained move set is derived from the mating condition that allows the transformation of a component in each mating pair to be fully or partially constrained with respect to the other. By using mating in the packaging, the number of components to be placed can be reduced significantly and overall speed of the packaging process can also be improved. The hybrid method uses a genetic algorithm to search mating pairs and global positions of selected objects. The mating pair is mated first by a simple mating condition which is derived from geometric features of mating objects. If a proper mating is not obtained, the complex mating algorithm finds an optimal mating condition using Quasi-Newton method.

Abstract:
Abstract A new method is being developed to automatically generate an optimal solution of the two-dimensional layout problem. Finding the optimal solution of a layout design problem, especially that of irregular shapes, is quite difficult and requires an extensive amount of computation mainly due to the combinatorial nature of the problem. In this work, each object is categorized into either a mating or a non-mating group based on its concavity features. Each mating object is then decomposed into sets of convex objects and its mating conditions are then checked with other mating objects. Based on mating conditions, two or more objects are mated to form a mating pair. After the mating pool of possible candidate mating pairs is generated, the genetic algorithm generates an optimal packing sequence of the mating group as well as the non-mating group. Then, local positional arrangement of each object in the sequence is determined to get a final solution.

Abstract:
Abstract It is desirable to provide computer-based tools to assist designers and manufacturing engineers in the difficult task of geometric reasoning to achieve fast product development and flexible manufacturing. In the domain of assembly reasoning and planning, numerous methods have been developed to analyze a user-specified assembly configuration of parts. Fewer efforts have been made to systematically obtain the assembly configuration itself from underlying information. As a step in this direction, we present an assembly mating reasoning method that determines feasible assembly configurations directly from part geometry. Our method recognizes form features from the boundary representations of the components, then treats the form features as assembly features and identifies mating relations between them. Assembly configurations are constructed by using Boolean operations on the components to simulate the assembly process. A heuristic backtracking search is used to traverse the space of feasible component assembly operations. The result of the search is an enumeration of feasible assembly configurations.

Abstract:
The research problem. Understanding of insect reproduction has been critical to the design of insect pest control strategies including disruptions of mate-finding, courtship and sperm transfer by male insects. It is well known that males transfer proteins to females during mating that profoundly affect female reproductive physiology, but little is known about the molecular basis of female mating response and no attempts have yet been made to interfere with female post-mating responses that directly bear on the efficacy of fertilization. The female reproductive tract provides a crucial environment for the events of fertilization yet thus far those events and the role of the female tract in influencing them are poorly understood. For this project, we have chosen to focus on the lower reproductive tract because it is the site of two processes critical to reproduction: sperm management (storage, maintenance, and release from storage) and fertilization. E,fforts during this project period centered on the elucidation of mating responses in the female lower reproductive tract The central goals of this project were: 1. To identify mating-responsive genes in the female lower reproductive tract using DNA microarray technology. 2. In parallel, to identify mating-responsive genes in these tissues using proteomic assays (2D gels and LC-MS/MS techniques). 3. To integrate proteomic and genomic analyses of reproductive tract gene expression to identify significant genes for functional analysis. Our main achievements were: 1. Identification of mating-responsive genes in the female lower reproductive tract. We identified 539 mating-responsive genes using genomic and proteomic approaches. This analysis revealed a shift from gene silencing to gene activation soon after mating and a peak in differential gene expression at 6 hours post-mating. In addition, comparison of the two datasets revealed an expression pattern consistent with the model that important reproductive proteins are pre-programmed for synthesis prior to mating. This work was published in Mack et al. (2006). Validation experiments using real-time PCR techniques suggest that microarray assays provide a conservativestimate of the true transcriptional activity in reproductive tissues. 2.lntegration of proteomics and genomics data sets. We compared the expression profiles from DNA microarray data with the proteins identified in our proteomic experiments. Although comparing the two data sets poses analyical challenges, it provides a more complete view of gene expression as well as insights into how specific genes may be regulated. This work was published in Mack et al. (2006). 3. Development of primary reproductive tract cell cultures. We developed primary cell cultures of dispersed reproductive tract cell types and determined conditions for organ culture of the entire reproductive tract. This work will allow us to rapidly screen mating-responsive genes for a variety of reproductive-tract specifi c functions. Scientific and agricultural significance. Together, these studies have defined the genetic response to mating in a part of the female reproductive tract that is critical for successful fertllization and have identified alarge set of mating-responsive genes. This work is the first to combine both genomic and proteomic approaches in determining female mating response in these tissues and has provided important insights into insect reproductive behavior.

Abstract:
t The pink bollworm, Pectinophoragossypiellais a key pest of cotton world-wide. In Israel mating disruption sex pheromone is used in all cotton fields and recent repeated outbreaks of the pest populations has suggested a change in the population sex pheromone characteristics. The research goals were to (1) determine the change in pheromone characteristic of PBW females after long experience to Mating Disruption (MD), (2) to test the male’s antennae response (EAG) to pheromone characteristics of laboratory, naive females, and of field collected, MD experienced females, (3) to analyse the biosynthetic pathway for possible enzyme variations, (4) to determine the male behavioural response to the pheromone blend involved in the resistance to MD. The experiments revealed that (1) MD experienced females produced pheromone blend with higher ZZ ratio than lab reared (MD naive females) that typically produced ZZ:EE ratio of 1:1. (2) Male’s origin did not affect its response to pheromone characteristics of lab or field females. (3) A transcriptome study demonstrated many gene-encode enzymes in the biosynthetic pathway, but some of the transcripts were produced in differing levels in the MD resistant populations. (4) Male origin (field or lab) influenced males’ choice of mate with strong preference to females sharing the same origin. However, when MD was applied, males of both populations were more attracted to females originated form failed MD treated fields. We conclude that in MD failed fields a change in the population mean of the ratio of the pheromone components had occurred. Males in these fields had changed their search “image” accordingly while keeping the wide range of response to all pheromone characteristics. The change in the pheromone blend is due to different level of pheromone related enzyme production.
