During coastal wetland restoration, foundation plant species are critical in creating habitat, modulating ecosystem functions, and supporting ecological communities. Following initial hydrologic can help stabilize sediments jump‐start development. Different species, however, have different traits environmental tolerances. To understand how these tolerances impact restoration trajectories, there is a need for comparative studies among species. In subtropical tropical climates, practitioners...
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...
<title>Abstract</title> Tidal wetlands are hotspots of soil accumulation due to high sedimentation rates and low oxygen concentrations that inhibit organic matter decomposition1. Accordingly, tidal can sequester “blue carbon” at much higher than other ecosystems2,3 helping offset human emissions. Organic carbon burial is tightly linked the cycling nitrogen, which a key pollutant limiting nutrient for many ecosystems4–6. Yet, current global rate nitrogen” how it may respond future change...
Abstract Coastal wetlands, including seagrass meadows, emergent marshes, mangroves, and temperate tidal swamps, can efficiently sequester store large quantities of sediment organic carbon (SOC). However, SOC stocks may vary by ecosystem type along environmental or climate gradients at different scales. Quantifying such variability is needed to improve blue accounting, conservation effectiveness, restoration planning. We analyzed in 1,284 cores >6,500 km the Pacific coast North America...
Abstract Plant‐mediated processes determine carbon (C) cycling and storage in many ecosystems; how plant‐associated may be altered by climate‐induced changes environmental drivers is therefore an essential question for understanding global C cycling. In this study, we hypothesize that alterations associated with near‐term climate change can exert strong control on ecosystem investigations along extended hydrologic gradient give mechanistic insight into We utilize a mesocosm approach to...
Abstract Extensive global estuarine wetland losses have prompted intensive focus on restoration of these habitats. In California, substantial tracts freshwater, brackish and tidal wetlands been lost. Given the anthropogenic footprint development urbanization in this region, must rely conversion existing habitat types rather than adding new wetlands. These restorations can cause conflicts among stakeholders species that win or lose depending identified priorities. Suisun Marsh San Francisco...
Abstract Disturbances are a key component of ecological processes in coastal ecosystems. Investigating factors that affect tidal marsh accretion and elevation change is important, largely due to accelerating sea‐level rise the economic value wetlands. Sediment accumulation rates, change, flooding were examined at five marshes along riverine‐tidal gradient northern San Francisco Bay‐Delta, California, USA during an Atmospheric River storm event 2017 using Surface Elevation Tables (SETs),...
Abstract Stress gradients influence many ecosystem processes and properties, including recovery from resistance to disturbance. While recent analytical approaches have advanced multivariate metrics of resilience that allow quantification conceptual models identification thresholds state change, these are not often translated landscape scales. Using natural restored salt marshes in Louisiana, USA, we quantified plant community along flooding stress gradients. n ‐dimensional hypervolumes...
<title>Abstract</title> Ongoing climate change is leading to shifting vegetation patterns in coastal areas worldwide. One such shift the ability of tropical species establish and survive farther north than they would have past. A well-studied example this tropicalization expansion mangroves at marsh-mangrove ecotone, thought be controlled by a decrease extreme freeze events SE USA. However, accurate mangrove distribution data their poleward limit region currently lacking. Here, we report...
Abstract Understanding patterns of biodiversity is a key goal ecology and especially pressing in the current human‐caused crisis. In wetland ecosystems, human impacts are centered around hydrologic manipulation including common practice diking impoundment. Constraining how management influences plant across spatial scales will provide information on best to modify actions preserve ecosystem function managed wetlands. Here, we compare diversity species presence, abundance, community...
Abstract Coastal wetlands are hotspots of carbon sequestration, and their conservation restoration can help to mitigate climate change. However, there remains uncertainty on when where coastal wetland most effectively act as natural solutions (NCS). Here, we synthesize current understanding illustrate the requirements for benefit climate, discuss potential paths forward that address key uncertainties impeding implementation. To be effective NCS, projects will accrue cooling benefits would...
The central notion of the accident proneness concept is that people exposed to equivalent hazards do not have an equal number accidents. If were equally prone, one would expect accidents be distributed according chance. Using data collected at Shell Oil Company's Manufacturing Complex in Deer Park, Texas, present study explored for major (OSHA recordable) and minor by comparing observed distribution a chance distribution. database contains information on 7131 which occurred between 1981...
Understanding the drivers of variability in plant diversity from local to landscape spatial scales is a challenge ecological systems. Environmental gradients exist at several and can be nested hierarchically, influencing patterns complex ways. As community dynamics influence ecosystem function, understanding across space paramount for predicting potential shifts function global change. Determining which stress vegetation composition crucial inform management restoration tidal marshes...
