Abstract. Tidal wetlands, such as tidal marshes and mangroves, are hotspots for carbon sequestration. The preservation of organic matter (OM) is a critical process by which wetlands exert influence over the global cycle at same time gain elevation to keep pace with sea-level rise (SLR). present study assessed effects temperature relative sea level on decomposition rate stabilization OM in worldwide, utilizing commercially available standardized litter. While per se were minor, we show strong...
Abstract Salt marshes and other blue carbon ecosystems have been increasingly recognized for their (C)‐sink function. Yet, an improved assessment of organic ( OC ) stocks C‐sequestration rates is still required to include C in C‐crediting programs. Particularly, factors inducing variability the permanence sequestration allochthonous contributions soil require understanding. This study evaluates potential long‐term semi‐natural salt European Wadden Sea WS ), conducting deep (1.3 m) down‐core...
Abstract The breakdown of plant material fuels soil functioning and biodiversity. Currently, process understanding global decomposition patterns the drivers such are hampered by lack coherent large‐scale datasets. We buried 36,000 individual litterbags (tea bags) worldwide found an overall negative correlation between initial mass‐loss rates stabilization factors plant‐derived carbon, using Tea Bag Index (TBI). factor quantifies degree to which easy‐to‐degrade components accumulate during...
Abstract Tidal wetlands have been increasingly recognized as long‐term carbon sinks in recent years. Work on sequestration and decomposition processes tidal focused so far mainly effects of global‐change factors such sea‐level rise increasing temperatures. However, little is known about land use, livestock grazing, organic matter ultimately sequestration. The present work aims at understanding the mechanisms by which large herbivores can affect wetlands. This was achieved studying both...
In addition to the well-studied impacts of defecation and defoliation, large herbivores also affect plant arthropod communities through trampling, associated soil compaction. Soil compaction can be expected particularly important on wet, fine-textured soils. Therefore, we established a full factorial experiment defoliation (monthly mowing) (using rammer, annually) clay-rich salt marsh at Dutch coast, aiming disentangle importance these two factors. Additionally, compared effects physical...
Abstract. Salt marshes play an important role in the global carbon cycle due to large amount of organic stored their soils. Soil formation these coastal wetland ecosystems is strongly controlled by plant primary production and initial decomposition rates belowground biomass litter. This study used a field warming experiment investigate response litter breakdown rising temperature (+1.5 +3.0 ∘C) across whole-soil profiles (0–60 cm soil depth) entire intertidal flooding gradient ranging from...
Abstract Salt marshes occur globally across climatic and coastal settings, providing key linkages between terrestrial marine ecosystems. However, salt marsh science lacks a unifying conceptual framework; consequently, historically well‐studied locations have been used as normative benchmarks. To allow for more effective comparisons the diversity of marshes, we developed an integrative framework. We review ecosystem‐relevant drivers from global to local spatial scales, integrate these...
Saltmarshes are widely thought to sequester carbon at rates significantly exceeding those found in terrestrial environments. This ability arises from the in-situ production of plant biomass and effective trapping storage both autochthonous allochthonous organic carbon. The role saltmarshes play climate change mitigation, through accumulating 'blue' carbon, depends on rate which accumulates within sediments rapidity with is remineralised. It has been hypothesised that accumulation rates,...
Abstract Tidal wetlands are effective carbon sinks, mitigating climate change through the long‐term removal of atmospheric CO 2 . Studies along surface‐elevation and thus flooding‐frequency gradients in tidal often used to understand effects accelerated sea‐level rise on sequestration, a process that is primarily determined by balance primary production microbial decomposition. It has been hypothesized rates decomposition would increase with elevation associated increases soil oxygen...
There is interest in using saltmarsh restoration, and that of other so-call blue carbon ecosystems, as a natural climate solution owing to the ability these wetlands sequester store high amounts organic their sediments. Given this, it important consider if restored saltmarshes come function same way natural, established habitats type, determine permanence origin stored sediments.Several existing UK have not had stocks sequestration rates assessed. Furthermore, numerous studies do exist...
Abstract. The persistence of tidal wetland ecosystems like salt marshes is threatened by human interventions and climate change. In particular, the threat accelerated sea level rise (SLR) has increasingly gained attention scientific community recently. However, studies investigating effect SLR on plants vertical marsh accretion are usually restricted to species or do not consider phenotypic plasticity genetic diversity. To investigate response genotypes within same salt-marsh SLR, we used...
Abstract Questions What are the main drivers of vegetation succession and encroachment Elymus athericus (Link) Kerguélen in ungrazed Wadden Sea salt marshes? Is (a) elevation, a proxy for tidal inundation thus abiotic conditions, limiting expanse . Does sedimentation increase spread by (b) leading to surface elevation change or does it (c) add nitrogen thereby allows grow lower elevation? Location Salt marsh at Sönke‐Nissen‐Koog, National Park Schleswig‐Holstein, Germany. Methods The...
Abstract Although tidal marshes are known for their coastal defense function during storm surges, the impact of extreme wave forcing on marsh development is poorly understood. Seedling survival in first season after germination, which may involve exposure to events, crucial natural establishment and human restoration marshes. We hypothesize that species‐specific plant traits plays a significant role seedlings response induced stress, i.e., through stem bending uprooting. To test this...
