Insects are a group of animals that contribute significantly to the proper functioning of different ecosystems on the planet. They provide services such as pollinating crops, recycling nutrients and controlling pests. Many scientific publications and reports have studied the current global decline of insects. This decline can severely affect other groups of animals including birds, reptiles, amphibians, fish, and small mammals that utilize insects as a source of food. This will have a great impact on the trophic cascade and an eventual adverse effect on the overall ecosystem. This book provides insights into the possible reasons behind the decline of insects as well as potential measures that might mitigate this decline. It contains eleven chapters written by different experts. The book is useful for a wide range of readers including entomologists, ecologists, botanists, environmentalists, and amateurs who love collecting and preserving insects.

Ils ne causeraient que des problèmes. Collisions routières, dégâts agricoles, raids urbains, transmission de virus...En somme, ils ne seraient rien d'autre qu'une menace. Pourtant, les sangliers ont longtemps été le symbole de la "nature sauvage", un noble gibier, la bête noire des forêts. Que leur avons nous fait ? Et que font-ils de nous ? Les sangliers sont parmi nous. Ce sont des acteurs à part entière des plaines et des montagnes comme des villes et de leurs banlieues. Ils se caractérisent par leur mobilité, leur capacité d'adaptation, leur imprévisibilité. lls résistent à la domination et contrarient nos actions. Les sangliers nous déroutent. Mêlant expériences naturalistes, connaissances écologiques et cynégétiques, cet ouvrage invite à une immersion littéraire et scientifique dans la vie commune des sangliers. Avec eux, demandons-nous comment cohabiter avec ce vivant qui, bien souvent, nous dépasse.

Les progrès fulgurants de la paléogénétique - l'analyse de l'ADN contenu dans les ossements anciens - permettent de reconstituer les flux migratoires qui ont façonné l'Europe au cours du temps. Dans ce livre, Johannes Krause et Thomas Trappe retracent le voyage de nos gènes et racontent ainsi celui des peuples qui ont fait notre continent. Nous sommes les descendants de trois grandes vagues d'immigration. Nous leur devons beaucoup : langues, structures sociales, arts et techniques, domestication des plantes et des animaux, héritages génétiques venus d'humains aujourd'hui disparus (néandertaliens et dénisoviens). Mais également des maladies comme la peste et d'autres pathogènes, compagnons de route d'une épopée qui a commencé lorsque Sapiens s'est aventuré hors d'Afrique, il y a 200 000 ans. Ce récit radicalement nouveau de notre histoire commune parle aussi du besoin irrépressible de l'homme de conquérir le monde et de franchir les obstacles. Les auteurs montrent que les problèmes qui nous préoccupent aujourd'hui, catastrophe climatique, épidémies mortelles, conflits ethniques, crise des réfugiés, etc., nous les avons déjà affrontés, et surmontés, par le passé.

"Les gènes sont une fascinante machine à remonter le temps depuis que nous savons faire "parler" non seulement l'ADN des Sapiens actuels, mais aussi celui de nos lointains ancêtres. En nous faisant partager les derniers résultats des laboratoires comme ses péripéties sur le terrain, Evelyne Heyer dévoile un récit qui semblait à jamais inaccessible : celui de l'aventure humaine. Dans cette grande fresque, vous cheminerez aux côtés de cousins disparus tels Néandertal et Denisova, ou du mystérieux peuple des steppes qui aurait imposé les langues indo-européennes. Au gré des migrations et des mélanges, vous suivrez les juifs de Boukhara, les armées de Gengis Khan. Vous embarquerez avec des esclaves africains depuis leurs pays d'origine, que révèlent les tests génétiques. Une odyssée qui éclaire aujourd'hui nos différences et façonnera demain notre avenir."
