Impact of Nature In its broadest sense, nature refers to the physical world around us and its components, including the atmosphere, oceans, landforms, and wildlife. It encompasses the diversity of flora and fauna, geological features, and the intricacies of weather patterns. In its most basic fo...
Ecosystems in this region are isolated by the Atacama Trench, the Humboldt Current System, and an extreme oxygen minimum zone. This isolation has produced a unique biodiversity that is marked by one of the highest levels of marine endemism on Earth. These areas also provide important habitats ...
This study examines the spatial variability of transport within the inner-shelf south of Martha's Vineyard Massachusetts, its time and space dependence, and its importance to the total volume exchanged between the nearshore and the coastal ocean. The exchange of water across the inner shelf is ...

which has greatly advanced because of the rapid progress in DNA sequencing technologies, concerns the distribution of microor- ganisms across space, and aims to identify under- lying mechanisms, which generate variation in community composition (that is, beta diversity) (Martiny et al., 2006). ...
