Ecosystem connectivity tends to increase the resilience and function of ecosystems responding stressors. Coastal sequester disproportionately large amounts carbon, but rapid exchange water, nutrients, sediment makes them vulnerable sea level rise coastal erosion. Individual components landscape (i.e., marsh, forest, bay) have contrasting responses rise, making it difficult forecast response integrated carbon sink. Here we couple a spatially-explicit geomorphic model with point-based...
Abstract The expansion of shrubs across the Arctic tundra may fundamentally modify land–atmosphere interactions. However, it remains unclear how shrub pattern is linked with key environmental drivers, such as climate change and fire disturbance. Here we used 40+ years high‐resolution (~1.0 m) aerial satellite imagery to estimate shrub‐cover in 114 study sites four burned unburned upland (ice‐poor) lowland (ice‐rich) ecosystems northern Alaska. Validated data from additional fires, our...
Abstract Saltmarsh is a major contributor to global blue carbon (C) sink. However, plant invasion and anthropic activities have greatly altered its distribution C function in the last decades. We used remote sensing data synthesis investigate how four decades of land reclamation affect spatiotemporal variation Yancheng saltmarshes, largest coastal ecosystem eastern China. revealed that exotic cordgrass, Spartina alterniflora , increased regional storage, mainly by seaward expansion cordgrass...
Abstract Ghost forests consisting of dead trees adjacent to marshes are striking indicators climate change, and marsh migration into retreating coastal is a primary mechanism for survival in the face global sea‐level rise. Models transgression typically assume inundation static topography instantaneous conversion forest with rising seas. In contrast, here we use four decades satellite observations show that many low‐elevation along US mid‐Atlantic coast have survived despite undergoing...
Abstract Consumers can directly (e.g., consumption) and indirectly trophic cascades) influence carbon cycling in blue ecosystems. Previous work found that large grazers have nuanced effects on stocks, yet, small, bioturbating‐grazers, which remove plant biomass alter sediment properties, remain an understudied driver of cycling. We used field‐derived remote sensing data to quantify how the purple marsh crab, Sesarma reticulatum , influenced flux, recovery salt marshes. caused a 40%–70% loss...
Ecogeomorphic theory predicts that plant-sediment feedbacks regulate carbon storage in coastal vegetated ecosystems. Yet, grazers, which remove plant biomass and alter sediment properties, remain an understudied driver of cycling. We used field-derived remote sensing data to examine how consumer fronts the keystone grazer, Sesarma reticulatum , mediate storage, flux, recovery salt marshes. observed accelerating rates front migration led a decrease stocks by 40-70%. Despite latitudinal...
Burn severity influences various biophysical and biogeochemical processes, it is projected to increase in the coming decades across high-latitude ecosystems. However, impact of burn on thermokarst (e.g., land subsidence after ground ice melting) not well understood. We used time-series image analysis assess effects content processes Noatak National Preserve, northwestern Alaska. To extend temporal depth for illustrating fire-thermokarst linkages, we evaluated eight existing fire indices...
