“…The stable isotope values in the bare plot of the exposed site in Horsens pointed to a content of more than 50% of terrestrial OM, suggesting that this bare site may not be comparable to its corresponding vegetated site. Considering previous studies nearby our exposed study site in Horsens, this terrestrial organic material could be gyttja deposits, OC‐rich and fine sediments deposited before the sea level rise during the late Pleistocene in low‐energy environments, formed from the partial decay of vegetation remains, and usually protected by eelgrass meadows above them (Skriver et al 2018). The proportion of eelgrass‐derived OM was higher in most vegetated plots as expected.…”

The ability of seagrass meadows to filter nutrients and capture and store CO 2 and nutrients in the form of organic carbon (OC) and nitrogen (N) in their sediments may help to mitigate local eutrophication as well as climate change via meadow restoration and protection. This study assesses OC and N sediment stocks (top 50 cm) and sequestration rates within Danish eelgrass meadows. At four locations, eelgrass-vegetated and nearby unvegetated plots were studied in protected and exposed areas. The average OC and N sediment 50 cm stocks were 2.6 AE 0.3 kg OC m À2 and 0.23 AE 0.01 kg N m À2 , including vegetated and unvegetated plots. In general, OC and N stocks did not differ significantly between eelgrass meadows and unvegetated sediments. Lack of accumulation of excess 210 Pb suggested sediment erosion or low rates of sediment accumulation at most sites. OC accumulation rates ranged from 6 to 134 g m À2 yr À1 and N from 0.7 to 14 g m À2 yr À1 . Generalized additive models showed that ≥ 80% of the variation in sediment OC and N stocks was explained by sediment grain size, organic matter source, and hydrodynamic exposure. Long cores, dated with 210 Pb, showed declining OC and N densities toward present time, suggesting long-term declines in eelgrass OC and N pools. Estimates of potential nation-wide OC and N accumulation in eelgrass sediments show that they could annually capture up to 0.7% AE 0.5% of CO 2 emissions and 6.9% AE 5.2% of the total terrestrial N load.

“…As for the two submerged environments they are not exposed to light or oxygen, but have an ample supply of sulphate and the results indicate a substantial sulphate reduction is ongoing in the most organic sediment layers ( S3 Fig ). Regarding the difference between the two submerged environments the gyttja environment is a well-known archaeological site [ 51 , 52 ], where the archaeology is preserved in the organic gyttja layers. The site is known to be under erosion [ 53 ] and the gyttja layers are relatively thin.…”

Bone biodeterioration—The effect of marine and terrestrial depositional environments on early diagenesis and bone bacterial community

Bacteria play an important role in the degradation of bone material. However, much remains to be learnt about the structure of their communities in degrading bone, and how the depositional environment influences their diversity throughout the exposure period. We genetically profiled the bacterial community in an experimental series of pig bone fragments (femur and humeri) deposited at different well-defined environments in Denmark. The bacterial community in the bone fragments and surrounding depositional environment were studied over one year, and correlated with the bioerosion damage patterns observed microscopically in the bones. We observed that the bacterial communities within the bones were heavily influenced by the local microbial community, and that the general bone microbial diversity increases with time after exposure. We found the presence of several known collagenase producing bacterial groups, and also observed increases in the relative abundance of several of these in bones with tunneling. We anticipate that future analyses using shotgun metagenomics on this and similar datasets will be able to provide insights into mechanisms of microbiome driven bone degradation.

Gelişimin sağlanabilmesi açısından bu alandaki incelenip, ülkemizdeki çalışmalara katkılarının olup olamayacağı tartışmalarının yapılmasının faydalı olabileceği düşünülmektedir (Astrup et al, 2020;Benjamin, 2010;Bicket & Tizzard, 2015;Donahue et al, 2019;Fischer et al, 2007;Hansson et al, 2018;Lodolo & Ben-Avraham, 2015;Momber, 2000;Skriver et al, 2018;Vos et al, 2015;Ward et al, 2019;Westley, 2015;Westley et al, 2011).
