A collaboration of American researchers demonstrated in a new study that the lifetime movements of trout in large river systems can be tracked by analyzing their earbones. These results may be used to develop a new method of studying the fish unobtrusively.
Details of the research were published in the latest issue... |

Studies on the origins of Homo sapiens have revealed that our species most likely appeared in tree-dotted savannas, somewhere in central-eastern Africa. But a new proposal says that our ancestors may have evolved on the banks of major rivers as well.
The fact that rivers played an important role in human history is... |

Scientists have recently determined that some of the world's most pristine and clean waterways may be at an elevated risk of suffering from the ill-effects of algal invasions. The reason for that is the fact that the waters are so clean, experts now indicate in a new study.In other words, the very fact that thes... |

One of the things the Swiss Alps are famous for is the impressive number of gorges they contain. These landscape features are monumental in scale and grandeur, and also very difficult for geologists to explain. A recent study proposes a new approach to explaining the gorges' existence. According to researchers b... |

Experts have determined a long time ago that the Amazon River, as one of the largest bodies of flowing water in the world, plays an important part in the world's water cycle. They therefore set out to investigate how the river's floods influence its volume and spread throughout the floodplains. The satellit... |

In recent years, Canadian officials have been happy to discover that their country has a large reserve of oil at its disposal, which means that the precious stuff no longer has to be carried from far away and imported at high prices. The only catch is that the oil they found was trapped inside tar sand. Extracting th... |

Scientists have determined that the current global-warming phenomenon will not lead to all the river deltas in the world being swamped. A multitude of factors will determine which of the landscape features will be destroyed or not, including the level of tectonic activity in plates around their locations, and the typ... |

Lakes are classified depending on how they formed and on the quality of the water (freshwater or saltwater). Only in the saltiest lakes there is no life. Lakes contain 4 times more freshwater than the rivers, but, if they are not continuously supplied with freshwater, they can disappear through dessication or accumul... |
