Ecology Letters (2011) Abstract Understanding the sensitivity of tundra vegetation to climate warming is critical forecasting future biodiversity and feedbacks climate. In situ experiments accelerate change on a small scale forecast responses local plant communities. Limitations this approach include apparent site‐specificity results uncertainty about power short‐term studies anticipate longer term change. We address these issues with synthesis 61 experimental studies, up 20 years duration,...
A mixing model derived from first principles describes the bulk density (BD) of intertidal wetland sediments as a function loss on ignition (LOI). The assumes that volume sediment equates to sum self-packing volumes organic and mineral components or BD = 1/[LOI/k1 + (1-LOI)/k2], where k1 k2 are densities pure inorganic components, respectively. explained 78% variability in total when fitted 5075 measurements drawn 33 wetlands distributed around conterminous United States. values were...
Warmer temperatures are accelerating the phenology of organisms around world. Temperature sensitivity might be greater in colder, higher latitude sites than warmer regions, part because small changes temperature constitute relative thermal balance at colder sites. To test this hypothesis, we examined up to 20 years data for 47 tundra plant species 18 high-latitude along a climatic gradient. Across all species, timing leaf emergence and flowering was more sensitive given increase summer...
As urban populations continue to grow through the 21st century, more people are projected be at risk of exposure climate change-induced extreme events. To investigate complexity floods, this study applied an interlinked social-ecological-technological systems (SETS) vulnerability framework by developing flood index for six US cities. Indicators were selected reflect and illustrate exposure, sensitivity, adaptive capacity flooding each three domains SETS. We quantified 18 indicators...
As rates of urbanization and climatic change soar, decision-makers are increasingly challenged to provide innovative solutions that simultaneously address climate impacts risks inclusively ensure quality life for urban residents. Cities have turned nature-based help these challenges. Nature-based solutions, through the provision ecosystem services, can yield numerous benefits people multiple challenges simultaneously. Yet, efforts mainstream impaired by complexity interacting social,...
The rapidly warming temperatures in high-latitude and alpine regions have the potential to alter phenology of Arctic plants, affecting processes ranging from food webs ecosystem trace gas fluxes. International Tundra Experiment (ITEX) was initiated 1990 evaluate effects expected rapid changes temperature on tundra plant phenology, growth community using experimental warming. Here, we used ITEX control data test phenological responses background variation across sites spanning latitudinal...
Abstract Tidal wetlands produce long-term soil organic carbon (C) stocks. Thus for accounting purposes, we need accurate and precise information on the magnitude spatial distribution of those We assembled analyzed an unprecedented core dataset, tested three strategies mapping stocks: applying average value from synthesis to mapped tidal wetlands, models fit using empirical data applied soil, vegetation salinity maps, relying independently generated maps. Soil stocks were far lower varied...
Hurricanes are recurring high-energy disturbances in coastal regions that change community structure and function of mangrove wetlands. However, most the studies assessing hurricane impacts on mangroves have focused negative effects without considering positive influence hurricane-induced sediment deposition associated nutrient fertilization productivity resilience. Here, we quantified how Hurricane Irma influenced soil pools, vertical accretion, plant phosphorus (P) uptake after its passage...
ABSTRACT Mangrove forests are typically considered resilient to natural disturbances, likely caused by the evolutionary adaptation of species‐specific traits. These ecosystems play a vital role in global carbon cycle and responsible for an outsized contribution burial enhanced sedimentation rates. Using eddy covariance data from two coastal mangrove Florida Coastal Everglades, we evaluated impact hurricanes have on forest structure function measuring recovery pre‐disturbance conditions...
More than half of the original Everglades extent formed a patterned peat mosaic elevated ridges, lower and more open sloughs, tree islands aligned parallel to dominant flow direction. This ecologically important landscape structure remained in dynamic equilibrium for millennia prior rapid degradation over past century response human manipulation hydrologic system. Restoration is one primary objectives restoration effort. Recent research has revealed that three main drivers regulated...
The authors summarize the main findings of Florida Coastal Everglades Long-Term Ecological Research (FCE-LTER) program in EMER, within context Comprehensive Restoration Plan (CERP), to understand how regional processes, mediated by water flow, control population and ecosystem dynamics across EMER landscape. Tree canopies with maximum height <3 m cover 49% particularly SE region. These scrub/dwarf mangroves are result a combination low soil phosphorus (P < 59 μg P g dw−1) calcareous marl...
Coastal wetlands store carbon dioxide (CO2) and emit CO2 methane (CH4) making them an important part of greenhouse gas (GHG) inventorying. In the contiguous United States (CONUS), a coastal wetland inventory was recently calculated by combining maps type change with soil, biomass, CH4 flux data from literature review. We assess uncertainty in this developing monitoring system to quantify confidence process itself prioritize future research. provide value-added analysis defining types scales...
Abstract Coastal wetlands are globally important sinks of organic carbon (C). However, to what extent wetland C cycling will be affected by accelerated sea‐level rise ( SLR ) and saltwater intrusion is unknown, especially in coastal peat marshes where water flow highly managed. Our objective was determine how the ecosystem balance influenced elevated salinity. For two years, we made monthly situ manipulations salinity freshwater FW brackish BW sites within Everglades National Park, Florida ,...
Policies concerning renewable energy transition are the primary responsibilities of individual states in United States. This article aims to provide a comprehensive evaluation state-level policies, focusing on identifying key factors driving successful transitions and offering actionable insights for policymakers. The research investigates: What critical indicators strategies contributing an effective at state level? To ensure meaningful comparisons, were selected based top bottom...
Abstract Coastal communities in the Southeast U.S.A. face increasing risks from storm surge, extreme rainfall, and rising sea levels, highlighting need for effective monitoring response systems. Ocean Observing Regional Association launched Water Level Network 2021 to address these challenges, partnering with academic, federal, nonprofit, commercial organizations install operate lower-cost, real-time water level stations. This initiative, focused on vulnerable flooding, enhances resilience...
