About the Edition

In this thesis I report on a series of studies that addresses features of multiple mating and sexual selection in guppies (Poecilia reticulata ) and birds in general.In chapter 3, I tested the genetic incompatibility hypothesis by asking whether female guppies can bias their use of sperm toward more compatible males. Despite the deleterious consequences of inbreeding, there was no evidence of inbreeding avoidance in pre-copulatory behaviors of females or males, or in sperm use by females. These results suggest that female guppies do not discriminate on the basis of genetic relatedness, against closely related males or their sperm and as such do not multiply mate to avoid the costs of inbreeding depression.In chapter 5, I examined several ecological and behavioural factors in relation to testes size; an index of the extent of extrapair mating. The results of this chapter suggest that traditional ecological and behavioral variables can account for a significant portion of the variation in sperm competition in birds.In chapter 2, I test the trade-up hypothesis which is a behavioural strategy that females could use to maximize the genetic benefits to their offspring. The hypothesis proposes that females should be more willing to accept a mate when the new male encountered is a superior genetic source than previous mates. I found that females responsiveness to second males was an increasing function of male ornamentation. Attractive second males also sired a greater proportion of the offspring. These results suggest that female guppies may utilize pre-copulatory mechanisms to maximize the genetic quality of their offspring.In chapter 4, I tested whether female guppies could potentially accrue direct benefits from mate choice by assessing whether the orange, carotenoid-based integument pigmentation of male guppies signals male functional fertility, that is, their ability to supply a large number of high quality sperm at copulation. Males with greater areas of carotenoid colouration had significantly larger sperm loads and more motile sperm relative to males with relatively little carotenoid colouration. However, I found no evidence that sperm traits were related to the intensity of carotenoid colouration.

Understanding of animal social and sexual evolution has seen a renaissance in recent years with discoveries of frequent infidelity in apparently monogamous species, the importance of sperm competition, active female mate choice, and eusocial behavior in animals outside the traditional social insect groups. Each of these findings has raised new questions, and suggested new . Researchers in evolutionary ecology that want an overview of the current state of the field, and graduate students that want an introduction the field, will find this book very valuable. This volume can also be used as a primary textbook or supplemental reading in both upper division and graduate courses/seminars in Evolutionary Ecology.

There are thousands of papers and innumerable reviews about mate choice. A sensible starting point is a handful of books that cover mate choice and allied topics.

Cronin covers the long history of the field since Darwin first coined the term “sexual selection.” Evolutionary behavioral ecology. Oxford: Oxford Univ. Press. The popular consensus on mate choice has long been that females select mates likely to pass good genes to offspring.

In Mate Choice, Gil Rosenthal overturns much of this conventional ing the first synthesis of the topic in more than three evolutionary ecology of mate choice. book, and drawing from a wide range of fields, including animal behavior, evolutionary biology, social psychology.

(). The Evolutionary Psychology of Human Mate Choice. Journal of Psychology & Human Sexuality: Vol. 18, No.pp. Cited by:   In Darwin's discussion of this model, we find the only occurrence of a clear explanation for the evolution of mate choice in his entire book (ref. 2, Part I, p ): “Such pairs would have an advantage in rearing offspring, more especially if the male had the power to defend the female during the pairing-season, as occurs with some of the Cited by:   Thus, mate choice by females can be viewed as the first step in the process of paternity choice.

The incorporation of female perspectives into postcopulatory sexual selection has generated theoretical models for the evolution of multiple mating by females that in some ways parallel the mechanisms of mate choice evolution in Box 1.

It is characterized by a “selective response by animals to particular stimuli” which can be observed as behavior. In other words, before an animal engages with a potential mate, they first evaluate various aspects of that mate which are indicative of quality—such as the resources or.

The Living Elephants is the authoritative resource for information on both Asian and African elephants. From the ancient origins of the proboscideans to the present-day crisis of the living elephants, this volume synthesizes the behavior, ecology and conservation of elephants, while covering also the history of human interactions with elephants, all within the theoretical 4/5(1).

The Graduate Aptitude Test in Engineering (GATE) Exam exam is going to be held on Febru 02, 08 in multiple sessions. A separate exam in “Ecology and Evolution (EY)” discipline is conducted for the students interested in the areas of ecology, evolution and conservation science. It is high time for the GATE Ecology and Evolution.

The evolution of male mate choice: males can be choosy too. Sexual selection can occur whenever there is non-random mating and/or fertilisation, and results from mate choice or intrasexual competition for evolutionary significance of sexual selection is firmly established, but there has been a resurgence of interest over recent decades based upon: (i).

Search for. 2. Darwin's aesthetic theory of mate choice. The most revolutionary and challenging feature of Charles Darwin's proposed mechanism of evolution by mate choice is that it was explicitly repeatedly wrote of mating preferences as an ‘aesthetic faculty’ and described them as ‘a taste for the beautiful’.

The importance of mate choice and sexual selection has been emphasized by the majority of evolutionary psychologists. This paper assesses three cases of work on mate choice and sexual selection in evolutionary psychology: David Buss on cross-cultural human mate preferences, Randy Thornhill and Steve Gangestad on the link between mate preferences and.

These 'biological markets' can be examined to gain a better understanding of the underlying principles of evolutionary ecology. In this volume scientists from different disciplines combine insights from economics, evolutionary biology and the social sciences to look at comparative aspects of economic behaviour in humans and other animals.5/5(1).

Mate choice in human reproductive ecology is the process by which individuals rationally partner with others. Mate choice practices, like many of the topics in human reproductive ecology, vary greatly between individuals and between cultures.

Culture heavily influences mate choice, but there are evolutionary concepts that underpin research into.

consequence of the evolutionary avoidance of interspecific resource competition termed ‘ecological character displacement’.

If a trait is used both for resource utilization and for mate choice, Konuma and Chiba () showed that body size separation becomes more pronounced in the presence of reproductive interference. Using different numbers.

My long term.(source: Nielsen Book Data) Summary Known for their importance in regulating the population densities of pests, parasitoids have proven recently to be valuable tools with which to test aspects of evolutionary theory. This analysis of the biology of parasitoids also examines their behaviour, ecology and great diversity.
