Investors and Exploiters in Ecology and Economics - Principles and Applications

Philipp Heeb

Overview

In the natural world, some agents (investors) employ strategies that provide resources, services, or information, while others (exploiters) gain advantages through these efforts. This behavior coexists and can be observed in many species and at many levels. For example, bacteria depend on the existence of biofilms to synthesize constituent proteins ; cancerous cells employ angiogenesis to feed a tumor ; and parents forgo vaccinating their children yet benefit from herd immunity. Two independent research traditions have developed to analyze this behavior—one couched in evolutionary theory championed by behavioral ecologists, the other in social science concepts advocated by economists. In this book experts from economics, evolutionary biology, behavioral ecology, public health, and anthropology look for commonalities in understanding and approach.

The contributors consider parasitic strategies in ecological and economic terms ; the governance of natural resources, with insights from “producer-scrounger models,” forest management, and game theory ; human health, discussing therapeutic opportunities, public health economics, and the integration of perspectives ; and behavioral, social, and institutional consequences of exploitation strategies.

CP - Réchauffement climatique : la flore microbienne en danger ?

Julien Cote, Joël White

Les effets néfastes du changement climatique sur les espèces du microbiote intestinal1 d’un lézard viennent d’être mis en évidence par des chercheurs du laboratoire Évolution et diversité biologique de Toulouse (CNRS/Université Toulouse III - Paul Sabatier/ENSFEA/IRD), de la Station d’écologie théorique et expérimentale (CNRS/Université Toulouse III - Paul Sabatier) et de l’Université d’Exeter (Grande-Bretagne)2. Cette nouvelle étude à paraître dans la revue Nature Ecology & Evolution démontre l’urgence de mieux comprendre l’impact du climat sur les relations entre espèces afin de les protéger plus efficacement.
