Turbid and tannin-stained waterways are difficult habitats to study and present problems with respect to the management of aquatic fauna, and especially of endangered and cryptic animals such as manatees Trichechus spp. Linnaeus. Throughout much of the range of the extant trichechid species (T. inunguis, T. manatus, and T. senegalensis), the scientific approaches that are used successfully to document the status of the Florida subspecies (T. m. latirostris) are not feasible, due either to constraints associated with habitat or to the high costs involved. We examined the use of side-scan sonar as a novel way to acoustically detect free-ranging West …

Host–parasite associations are assumed to be ecologically specialized, tightly coevolved systems driven by mutual modification in which host switching is a rare phenomenon. Ecological fitting, however, increases the probability of host switching, creating incongruences between host and parasite phylogenies, when (1) specialization on a particular host resource is a shared characteristic of distantly related parasites, and (2) the resource being tracked by the parasite is widespread among many host species. We investigated the effect of ecological fitting on structuring the platyhelminth communities of anurans from a temperate forest and grassland in the United States and tropical dry and wet forests …
