Chapter Three – Host–Parasite Interactions and the Evolution of Immune Defense

Parasites and pathogens are ubiquitous and act as an important selection pressure on animals. Here, drawing primarily on our own research, mostly on insects, we illustrate how host-parasite interactions have played a role in the evolution of a range of phenomena, including animal coloration, social behavior, foraging ecology, sexual selection, and life-history tradeoffs, as well as how variation in host behavior and ecology can drive variation in parasitism risk and host allocation of resources to immunity and other antiparasite defenses. We conclude by identifying key areas for future study.

A “Child’s Rights Perspective”: The “Right” of Children and Young People to Participate in Health Care Research

As all human beings are consumers of health care provision across the life span and in receipt of care delivered by accountable health care professionals, all should have the right to be involved in shaping the future of their own health care. Rights-based participation, when applied successfully, has the potential to inform and influence the delivery of child health care, the child’s experience of health care, plus children’s nursing education (Coyne & Gallagher, 2011). The “right” of every child and young person to participate in research that relates to their own health care is also sustained by the author’s lead position as a Senior Lecturer in Higher Education for pre-registration children’s nursing in Northern Ireland and the appreciation of their voice when practicing as a registered children’s nurse and ward sister. The report provides an insight into seminal work on human and child rights; the historical context of children in Western society, and the evolution of children’s nursing amid the child’s right to participate in shaping their own health care.
