Nature –84 PubMed CrossRef Google Scholar   For pinnipeds, sea otters (Enhydra lutris), and some coastal cetaceans, the physical alteration of the littoral, including the mere presence of humans and their associated infrastructures, may be a significant detrimental factor. Noise pollution is a particular source of concern because many marine mammals rely on sound emission and detection

      Background Habitat modifications resulting from human transportation and power-generation infrastructure (e.g., roads, dams, bridges) can impede movement and alter natural migration patterns of aquatic animal populations, which may negatively affect survival and population viability. Full or partial barriers are especially problematic for migratory species whose life histories hinge on habitat ?id=/   A paper in the May issue of The Condor [(2)–, ] describes a repeatable and statistically robust approach to monitoring burrow nesting seabirds in the Salish Sea and the California Current that can be applied at single- or multi-island scales. The approach can be applied to both relatively common and important members of the
