Planktonic diatoms from sediment traps in Omura Bay, western Japan with implications for ecological and taphonomic studies of coastal marine environments

Diatom fluxes in a tropical, oligotrophic lake dominated by large-sized phytoplankton

“…The theoretical sedimentation rate of Cyclotella alchichicana has been calculated at about 4 m day -1 , considering 15 days to sink from the surface to the bottom of the lake. In the deepest traps, C. alchichicana still showed chloroplast content that indicated a fast sinking rate as suggested by other authors (e.g., Sommer, 1984;Lange et al, 1994;Kato et al, 2003).…”

Application of sediment traps in global change research in mountain lakes

“…This suggests that fragmentation and dissolution of fossil Cladocera occurs in the boundary zone between lake water and the surface sediments. Kato et al (2003) reported that most marine diatom frustles are lost at the surface sediments. Ryves et al (2003) and Battarbee et al (2005) also found high loss of diatoms at the mud-water interface.…”

“…Various numerical approaches have been applied to evaluate ecological compatibility of fossil assemblage to a living community of deep marine and lacustrine environments (Kato et al 2003;Park et al 2003). Some authors have also tried to understand time averaging processes of freshwater diatoms in smaller lakes in Europe (e.g., Cameron 1995).…”

“…Until recently, majority of taphonomic investigations are focused on terrestrial and marine biota (Morlan and Matthews 1983;Kato Et Al. 2003;Fuji and Matsuoka 2006).…”

1000 years of climate variability in central Asia: assessing the evidence using Lake Baikal (Russia) diatom assemblages and the application of a diatom-inferred model of snow cover on the lake

“…Comparisons between plankton and traps (open and sequencing) throughout the water column in the deep southern basin (1400+ m depth) suggest that, although death assemblages become progressively more dissolved as they descend through the water column, only c.10% of valves are lost here. While taxa are unequally affected by dissolution, with Nitzschia acicularis and finer Synedra acus varieties especially prone to losses in the water column, it is only at the sediment surface/water interface that major dissolution occurs, similar to the marine environment (e.g., see Treppke et al, 1996;Kato et al, 2003). In the southern basin, differences both within diatom assemblages, including all sample types from plankton, traps, and surface sediments (0-1400+ m), and within the surface sediments alone (950-1400 m depth) were not related to depth (Ryves et al, 2003).…”
