Download or read book Prudent Females Effects of Food Availability and Predation Risk on Female Investment in Offspring written by Nicole Elizabeth Krauss and published by . This book was released on 2018 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life history theory posits a trade-off between investment in self and reproduction depending on environment. Because of their increased investment in prenatal offspring, females in particular may exercise prudence if environmental conditions are unfavorable. Changes in female investment can alter offspring phenotype, resulting in non-genetic plastic changes known as maternal effects, which can have lasting effects into adulthood. We asked how predation risk and food availability alter female investment in offspring in a migratory passerine bird, the black-throated blue warbler (Setophaga caerulescens ; BTBW). In chapter 1, we used an experimental approach to assess the effect of nest predation risk on female contributions to eggs. We found no difference in mass or yolk hormones between treatment and control eggs, suggesting that nest predation risk does not affect female investment during egg formation. In chapter 2, we explored how variation in food availability during egg formation may limit or alter prenatal investment in offspring. Surprisingly, we did not find a relationship between energetic investment in clutches and food availability but did find a negative relationship between two anabolic yolk androgens, testosterone and androstenedione, and food availability. The negative relationship between yolk androgens and food availability suggests that females may decrease androgens when food is ample to avoid the costs of maintaining high levels of androgens, and instead promote increased growth of their nestlings through increased feeding. In chapter 3, we used a 14-year data set to evaluate the effect of predation risk on female investment in prenatal and postnatal offspring, as well as offspring condition. These data included surveys of nest predators in a subset of BTBW territories, as well as clutch size, female feeding rates, nestling mass, and nestling age at fledge. We found no relationship between predation risk, female investment in offspring, and nestling phenotype. Together these chapters highlight the persistent investment in reproduction of female BTBWs, as they did not decrease investment in response to increased predation risk and had limited response to changes in food availability. This may be because the probability of successfully breeding in the future is too low to decrease current investment.
Download or read book The Oxford Handbook of Women and Competition written by Maryanne L. Fisher and published by Oxford University Press. This book was released on 2017-08-14 with total page 857 pages. Available in PDF, EPUB and Kindle. Book excerpt: While women are generally perceived to be less competitive than men, women compete in many ways and in a variety of situations. Women try to make themselves look more attractive to draw the attention of a desirable mate. They will use gossip as a form of informational warfare to influence reputations. They compete as mothers to gain access to resources that directly influence the health of their children. They use selfies posted on social media to manipulate others' perceptions. Women compete all of their lives: in the womb, through adolescence and adulthood, and into their elder years. The topic of women's competition has gained significant momentum over the years. Edited by Maryanne L. Fisher, The Oxford Handbook of Women and Competition provides readers with direct evidence of this growth and is one of the first scholarly volumes to focus specifically on this topic. Fisher and her team of contributors offer a definitive worldview of the current state of knowledge regarding competition among women today. Many of the chapters are grounded within an evolutionary framework, allowing for authors to investigate the adaptive nature of women's competitive behaviors, motivations, and cognition. Other chapters rely on alternative frameworks, with contributors also asserting that socio-cultural forces are the culprit shaping women's competitive drives. Additionally, several contributors focus their attention on issues faced by adolescent girls, and explore the developmental trajectories for young women through adulthood. Designed to serve as a source of inspiration for future research and direction, The Oxford Handbook of Women and Competition is a stand-out scholarly text focusing on the many competitive forces driving women today.

Download or read book The Evolution of Social Behaviour written by Michael Taborsky and published by Cambridge University Press. This book was released on 2021-08-26 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can the stunning diversity of social systems and behaviours seen in nature be explained? Drawing on social evolution theory, experimental evidence and studies conducted in the field, this book outlines the fundamental principles of social evolution underlying this phenomenal richness.To succeed in the competition for resources, organisms may either 'race' to be quicker than others, 'fight' for privileged access, or 'share' their efforts and gains. The authors show how the ecology and intrinsic attributes of organisms select for each of these strategies, and how a handful of straightforward concepts explain the evolution of successful decision rules in behavioural interactions, whether among members of the same or different species. With a broad focus ranging from microorganisms to humans, this is the first book to provide students and researchers with a comprehensive account of the evolution of sociality by natural selection.

Download or read book The Wood Pigeon written by R. K. Murton and published by Collins. This book was released on 2011-10-27 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Collins New Naturalist series is the longest-running and arguably the most influential natural history series in the world with over 100 volumes published in over 60 years. This edition is produced from an original copy by William Collins. While the mainstream New Naturalist volumes were initially intended to deal with broad subjects such as wild flowers, insects or National Parks, a parallel New Naturalist series of monographs on single species or related groups of species was also published between 1948 and 1971. There have been no additions since. Now, for the first time in over forty years, these best-selling volumes are available again. The New Naturalist monographs shared the same high standards of the main series and were envisioned as relatively short books of about 50,000 words, and in a smaller format than the main series. Artists Clifford and Rosemary Ellis were asked to design jackets for this series alongside the main series, which resulted in the same stunning, distinctive cover illustrations that had helped inspire an entire new generation of nature enthusiasts.
