Foraging is fundamental to animal survival and reproduction, yet it is much more than a simple matter of finding food; it is a biological imperative. Animals must find and consume resources to succeed, and they make extraordinary efforts to do so. For instance, pythons rarely eat, but when they do, their meals are large—as much as 60 percent larger than their own bodies. The snake’s digestive system is normally dormant, but during digestion metabolic rates can increase fortyfold. A python digesting quietly on the forest floor has the metabolic rate of thoroughbred in a dead heat. This and related foraging processes have broad applications in ecology, cognitive science, anthropology, and ...
All of life is a game, and evolution by natural selection is no exception. The evolutionary game theory developed in this 2005 book provides the tools necessary for understanding many of nature's mysteries, including co-evolution, speciation, extinction and the major biological questions regarding fit of form and function, diversity, procession, and the distribution and abundance of life. Mathematics for the evolutionary game are developed based on Darwin's postulates leading to the concept of a fitness generating function (G-function). G-function is a tool that simplifies notation and plays an important role developing Darwinian dynamics that drive natural selection. Natural selection may result in special outcomes such as the evolutionarily stable strategy (ESS). An ESS maximum principle is formulated and its graphical representation as an adaptive landscape illuminates concepts such as adaptation, Fisher's Fundamental Theorem of Natural Selection, and the nature of life's evolutionary game.
This book examines how young people who struggle with life's worst conditions somehow manage to overcome adversity, identifying significant factors that contribute to their resilience. The book presents information and decision making skills students need to make good decisions in the face of adversity; learning strategies and teaching techniques that facilitate student acquisition of good decision making skills; vignettes and specific examples of what a resilient youth looks like; real-world portraits of school communities that support resilience; and specific guidelines for creating conditions for resilience in the classroom. There are nine chapters in two parts. Part 1, "Supporting Eviden...

God, Sex, Science, Gender: An Interdisciplinary Approach to Christian Ethics is a timely, wide-ranging attempt to rescue dialogues on human sexuality, sexual diversity, and gender from insular exchanges based primarily on biblical scholarship and denominational ideology. Too often, dialogues on sexuality and gender devolve into the repetition of party lines and defensive postures, without considering the interdisciplinary body of scholarly research on this complex subject. This volume expands beyond the usual parameters, opening the discussion to scholars in the humanities, social sciences, and natural sciences to foster the development of Christian sexual ethics for contemporary times. Essa...
Foraging is fundamental to animal survival and reproduction, yet it is much more than a simple matter of finding food; it is a biological imperative. Animals must find and consume resources to succeed, and they make extraordinary efforts to do so. The book discusses the mechanics of foraging, modern foraging theory, and foraging ecology. The fourteen essays cover all the relevant issues, including cognition, individual behaviour, caching behaviour, parental behaviour, antipredator behaviour, social behaviour, population and community ecology, herbivory, and conservation.
An in-depth analysis of the impact conservation behaviour can have to develop practical tools to safeguard against biodiversity extinction.
Cancer cells exist in an ever-changing “ecology” and are subject to evolutionary pressures just like any species in nature. This edited book explores the following themes: 1) how the dynamics of mutation, epigenetics, and gene expression noise are sources of genetic diversity; 2) how scarce resources influence cancer therapy resistance; 3) how predator-prey dynamics are mirrored in immune-cancer cross-talk; 4) how cancer cells parallel niche construction theory; 5) how changing fitness landscapes enable cancer growth; and 6) how cancer cells interact within the body. The book is a resource for understanding cancer as a disease of multicellularity grounded in evolutionary principles. By u...
