Identification of Major Planktonic Sulfur Oxidizers in Stratified Freshwater Lake
Planktonic sulfur oxidizers are important constituents of ecosystems in stratified water bodies, and contribute to sulfide detoxification. In contrast to marine environments, taxonomic identities of major planktonic sulfur oxidizers in freshwater lakes still remain largely unknown. Bacterioplankton community structure was analyzed in a stratified freshwater lake, Lake Mizugaki in Japan. In the ...
متن کاملHidden diversity in the freshwater planktonic diatom Asterionella formosa.
Many freshwater and marine algal species are described as having cosmopolitan distributions. Whether these widely distributed morphologically similar algae also share a similar gene pool remains often unclear. In the context of island biogeography theory, stronger spatial isolation deemed typical of freshwater lakes should restrict gene flow and lead to higher genetic differentiation among lake...
متن کاملCoaggregation between freshwater bacteria within biofilm and planktonic communities.
The coaggregation ability of bacteria isolated from a freshwater biofilm was compared to those derived from the coexisting planktonic population. Twenty-nine morphologically distinct bacterial strains were isolated from a 6-month-old biofilm, established in a glass tank under high-shear conditions, and 15 distinct strains were isolated from the associated re-circulating water. All 44 strains we...
متن کاملTwo new genera and three new species of freshwater crabs (Crustacea: Pseudothelphusidae: Potamocarcinini) from Chiapas, Mexico.
Two new genera, Sylvathelphusa n. gen. and Tzotzilthelphusa n. gen., and three new species, Sylvathelphusa kalebi n. sp., S. cavernicola n. sp. and Tzotzilthelphusa villarosalensis n. sp., of the tribe Potamocarcinini, family Pseudothelphusidae, are described from Chiapas, Mexico. Sylvathelphusa n. gen. is characterized by a male gonopod with the marginal plate between the caudal and mesial sur...
متن کاملSeasonal patterns of bacterivory by flagellates, ciliates, rotifers, and cladocerans in a freshwater planktonic community
Bacterivory in eutrophic Lake Oglethorpe, Georgia, was determined by direct observation of tracer particle uptake by all members of the planktonic community. Heterotrophic flagellates dominated grazing at all times, accounting for 49-8 1% of grazing on an areal basis and up to 98% of grazing at some depths. Pigmented (mixotrophic) flagellates were major grazers during winter and spring blooms, ...
