"Sensors for ecology"

Ecological sciences deal with the way organisms interact with one another and their
environment. Using sensors to measure various physical and biological characteristics has been a common activity since long ago. However the advent of more accurate technologies and increasing computing capacities demand a better combination of information collected by sensors on multiple spatial, temporal and biological scales.
This book provides an overview of current sensors for ecology and makes a strong case for deploying integrated sensor platforms. By covering technological challenges
as well as the variety of practical ecological applications, this text is meant to be an invaluable resource for students, researchers and engineers in ecological sciences.
This book benefited from the Centre National de la Recherche Scientifique (CNRS) funds, and includes 16 contributions by leading experts in french laboratories.

Animal certifié conforme, Déchiffrer nos relations avec le vivant

Dans une nature menacée et menaçante, une solidarité de destins ne cesse de s’affirmer entre les hommes et les animaux : protéger ne suffit plus, il faut conserver et gérer.(Sous la direction de Bernadette Lizet et Jacqueline Milliet).

Les onze essais réunis dans cet ouvrage émanent de terrains de recherche qui
touchent à nos relations actuelles avec les animaux, complexes, empreintes
d’émotions, sous tension. Ces rapports sont désormais encadrés par un appareil
de règles et de normes juridiques, éthiques et morales, qui visent à élaborer
partout de nouveaux codes de « bonnes pratiques » pour assurer une coexistence
durable. Mais l’utopie d’une relation pacifique se heurte à de multiples
résistances.

L’homme peut-il s’adapter à lui-même ?

L’homme a rendu le monde nettement plus vivable pour lui-même en y augmentant son espérance de vie, en facilitant ses accès au garde-manger, à la fontaine municipale, au médecin de famille, à la pompe à essence, au train ou à… ses redoutables courriels. Ce faisant il a, d’un même geste, multiplié par cent sa facture énergétique comme sa production de carbone et de polluants, pillé les ressources halieutiques, érodé les terres arables, homogénéisé le vivant et, peut-être, mangé son pain blanc.

Long Term Socio-Ecological Research

The authors in this volume make a case for LTSER’s potential in providing insights, knowledge and experience necessary for a sustainability transition. This expertly edited selection of contributions from Europe and North America reviews the development of LTSER since its inception and assesses its current state, which has evolved to recognize the value of formulating solutions to the host of ecological threats we face. Through many case studies, this book gives the reader a greater sense of where we are and what still needs to be done to engage in and make meaning from long-term, place-based and cross-disciplinary engagements with socio-ecological systems.

How species interact - Altering the standard view of trophic ecology

Understanding the functioning of ecosystems requires the understanding of the interactions between consumer species and their resources. How do these interactions affect the variations of population abundances ? How do population abundances determine the impact of predators on their prey ? The view defended in this book is that the "null model" that most ecologists tend to use is inappropriate because it assumes that the amount of prey consumed by each predator is insensitive to the number of conspecifics. The authors argue that the amount of prey available per predator, rather than the absolute abundance of prey, is the basic determinant of the dynamics of predation. This so-called ratio dependence is shown to be a much more reasonable "null model."
