Also, the bioturbation
patterns indicate deposition during a single short-lived sedimentary event, rather than deposition during a more extended period in nearshore facies as suggested by Domzalski et al.
The bleaching of bones also provides clear evidence of bioturbation
at the cave's entrance (sun impact).
'Like worms in a garden, tiny creatures on the seabed disturb, mix and recycle dead organic material-a process known as bioturbation
,' said Tim Lenton, Professor at Britain's University of Exeter.
Burrowing species such as the Common Wombat may play a key role in ecosystem processes in Australia through bioturbation
(Fleming et al.
Ad) suggest that subsequent reworking by moving water and bioturbation
has contributed to the present fabric composition of the soil.
The modeled effects include fragmentation, Bioturbation
, Aggregation, Macropore formation and foodweb effects on soil organic matter decomposition, 2) to optimize and validate the new model using: I) historical experimental data obtained during long-term research at sokolov post-mining ecosystems lter site, Ii) additional literature and original data collected during the project for modelling purposes; 3) to compare performance of the new anafore soil submodel with the previous version of anafore and the yasso model as an example of a simple model that predicts organic matter decomposition only based on litter quality and abiotic factors.
Influence of Campsurus notatus bioturbation
on oxygen profile and uptake in sediments of an Amazonian lake impacted by bauxite tailings.
The ventilating activity of burrowing polychaetes, clams and other invertebrates (bioturbation
) implies that oxygen is brought into the sediment while methane-containing water is pumped up into the water column.
The subfamily Scarabaeinae (Coleoptera: Scarabaeidae) includes dung beetles (DB), a globally distributed group of detritus-feeding insects, determinant of ecological functions such as nutrient recycling, secondary seed dispersal, bioturbation
, and natural control of cattle parasites (Nichols et al., 2008; Simmons & Ridsdill-Smith, 2011).
The impact of ant bioturbation
and foraging activities on surrounding soil properties.
note, one of the principal problems in studying human bioturbation
is that "the extent and geological significance of subsurface crustal modifications are commonly neglected: out of sight, out of mind.

and impact of feeding activity of Holothuria (Haldeima) atra and Stichopus chloronotus, two sediment feeding holothurians, at Lizard Island, Great Barrier Reef," Bulletin of Marine Science, vol.
