Microbial eukaryote diversity in the marine oxygen minimum zone off northern Chile
Molecular surveys are revealing diverse eukaryotic assemblages in oxygen-limited ocean waters. These communities may play pivotal ecological roles through autotrophy, feeding, and a wide range of symbiotic associations with prokaryotes. We used 18S rRNA gene sequencing to provide the first snapshot of pelagic microeukaryotic community structure in two cellular size fractions (0.2-1.6 μm, >1.6 μ...
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 کاملContrasting macrobenthic activities differentially affect nematode density and diversity in a shallow subtidal marine sediment
By bioturbating and bio-irrigating the sea floor, macrobenthic organisms transport organic matter and oxygen from the surface to deeper layers, thereby extending the habitat suitable for smaller infauna. Next to these engineering activities, competition, disturbance and predation may also affect the spatial distribution of these smaller organisms. In a controlled laboratory experiment, we studi...
متن کاملSoft-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...
