Soft-Sediment Communities
arine sediments constitute one of the largest habitat types on Earth, covering roughly 80% of the ocean bottom (Lenihan and Micheli 2001; Nybakken and Bertness 2005). As a result, to truly understand the processes that shape communities on our planet, it is critical to understand the underpinnings of this habitat. In fact, much effort has been focused on studying this habitat (especially in nea...
متن کاملImportance of predatory infauna in marine soft-sediment communities
Ambrose (1984a) suggested that a 3-way interactive model should be applied to marine infaunal communities having the levels of epibenttuc predators, predatory infauna and nonpredatory infauna. It is shown that the 3-level interactive model incorporates the implicit, unstated assumption that epibenthlc predators preferentially prey on predatory infauna. A review of the literature reveals that th...
متن کاملCompetition and Predation in Marine Soft-sediment Communities
One of the major goals of community ecology is to understand how interactions among the resident organisms affect their distribution and abundance. For terrestrial and rocky intertidal communities competition and predation clearly can play pivotal roles in community organization (28, 47, 84). The importance of biological processes in organizing marine soft-sediment communities is not as well un...
متن کاملSoft quasicrystals – Why are they stable ?
In the last two years we have witnessed the exciting experimental discovery of soft matter with nontrivial quasiperiodic long-range order – a new form of matter termed a soft quasicrystal. Two groups have independently discovered such order in soft matter: Zeng et al. in a system of dendrimer liquid crystals; and Takano et al. in a system of ABC star-shaped polymers. These newly discovered soft...
متن کاملConsequences of Thymidine Catabolism for Estimates of Bacterial Production: An Example from a Coastal Marine Sediment
Radioactively labeled thymidine (TdR) has been used extensively to measure bacterial production in aquatic environments, but critical assumptions of the TdR technique often have gone untested. In this study of a coastal marine sediment, the metabolic fate of methyl [3H]TdR and methyl [14C]TdR was at variance with the assumptions necessary for determining bacterial production. Only 2% of incorpo...
