Eels grow in the fresh waters of rivers and lakes but reproduce in the oceans. Several species are known, all very similar to each other, both in the Atlantic and in the Pacific, capable of moving for thousands of kilometers, with migration systems that are among the most complex that […]
Mammals are animal species that have evolved from pre-existing reptiles in the terrestrial environment, undergoing extraordinary adaptive radiation [1]. But the lands are surrounded by seas, extremely productive ecosystems [2], and biodiversity that is unmatched on land. Thus some groups of them have started, in remote geological eras, a process […]

The visual and behavioral characteristics of the Common kingfisher have certainly not gone unnoticed and so, since ever, popular imagination has given these birds virtues and magical powers that certainly did not help their conservation, making them the object of hunting and easy hunting techniques: a viscous substance placed near […]
Migration is a completely dynamic phenomenon that over time has evolved in parallel with changing environmental and climatic conditions in particular. To maintain its character of survival strategy, the adaptive changes that migration must face are therefore continuous. As a result, the different species must optimize their movement strategies in […]
Among the reflections arabesqued by the sun on the water as soon as you notice a flash of blue that darting trilling before. In vain you pursue him … already has vanished behind the reeds: it was Martino, he was the king fisherman. From his behavior, from the colors of […]
