Abstract Mangroves sequester large quantities of carbon (C) that become significant sources greenhouse gases when disturbed through land‐use change. Thus, they are great value to incorporate into climate change adaptation and mitigation strategies. In response, a global network mangrove plots was established provide policy‐relevant ecological data relating interactions C stocks with climatic, tidal, plant community, geomorphic factors. from 190 sites were sampled across five continents...
An experiment in >1000 river and riparian sites found spatial patterns controls of carbon processing at the global scale.
Mangroves' ability to store carbon (C) has long been recognized, but little is known about whether planted mangroves can C as efficiently naturally established (i.e., intact) stands and in which time frame. Through Bayesian logistic models compiled from 40 years of data built 684 mangrove worldwide, we found that biomass stock culminated at 71 73% intact ~20 after planting. Furthermore, prioritizing mixed-species planting including
Concentrations, bioavailability, and export of dissolved organic matter (DOM), particulate (POM), nutrients from the Wailuku River, Hawai'i, U.S.A., were examined under base‐ stormflow conditions. During storms, DOM POM concentrations increased approximately by factors 2 11, respectively, whereas NO 3 − decreased a third. The carbon (OC) pool was dominated OC (DOC) during baseflow conditions, DOC contributed equally storms. nitrogen (N) conditions N (PON) Dissolved (DON) comprised similar...
Abstract Globally, mangrove forests represents only 0.7% of world's tropical forested area but are highly threatened due to susceptibility climate change, sea level rise, and increasing pressures from human population growth in coastal regions. Our study was carried out the Bhitarkanika Conservation Area ( BCA ), second‐largest eastern India. We assessed total ecosystem carbon (C) stocks at four land use types representing varying degree disturbances. Ranked order impacts, these sites...
Mangrove forests play an important role in climate change adaptation and mitigation by maintaining coastline elevations relative to sea level rise, protecting coastal infrastructure from storm damage, storing substantial quantities of carbon (C) live detrital pools. Determining the efficacy mangroves achieving goals can be complicated difficulty quantifying C inputs (i.e., differentiating newer younger trees older residual pools), assessments rarely consider potential offsets CO2 storage...
Rivers and streams contribute to global carbon cycling by decomposing immense quantities of terrestrial plant matter. However, decomposition rates are highly variable large-scale patterns drivers this process remain poorly understood. Using a cellulose-based assay reflect the primary constituent detritus, we generated predictive model (81% variance explained) for cellulose across 514 globally distributed streams. A large number variables were important predicting decomposition, highlighting...
Abstract Since cuspate coastlines are especially sensitive to changes in wave climate, they serve as potential indicators of initial responses changing conditions. Previous work demonstrates that Cape Hatteras and Lookout, North Carolina, which largely unaffected by shoreline stabilization efforts, have become increasingly asymmetric over the past 30 years, consistent with model predictions for coastline response increases Atlantic Ocean summer heights resulting distribution wave‐approach...
West Papua's Bintuni Bay is Indonesia's largest contiguous mangrove block, only second to the world's in Sundarbans, Bangladesh. As almost 40% of these mangroves are designated production forest, we assessed effects commercial logging on forest structure, biomass recovery, and soil carbon stocks burial five-year intervals, up 25 years post-harvest. Through remote sensing field surveys, found that canopy structure species diversity were gradually enhanced following recovery. Carbon pools...
Coastal regions are highly susceptible to the effects of global warming, including rising atmospheric and sea surface temperatures, increased cyclone frequency, level rise. Thus, it is imperative examine coastal vulnerability minimize impact multiple hazards protect resources, such as mangroves. Particularly in India studying zones Andaman Nicobar Islands which fall seismic zone V critical for conservation efforts. We conducted analysis impacted by 2004 earthquake, causing varying degrees...
River flow can impact which sources of particulate organic matter (POM) fuel estuarine food webs. Here, we used stable carbon (C) and nitrogen (N) isotope analyses to compare how contributions different POM (terrestrial, estuarine, marine) the diets zooplankton juvenile fishes differed between low high river conditions, as well spatially across a tropical estuary, Hilo Bay, Hawaii, USA. Diets were affected by but magnitude change in basal resources depended on location station estuary...
Poeciliids, one of the most invasive species worldwide, are found on almost every continent and have been identified as an “invasive concern” in United States, New Zealand, Australia. Despite their global prevalence, few studies quantified impacts tropical stream ecosystem structure, function, biodiversity. Utilizing Hawaiian streams model ecosystems, we documented how ecological native abundance differed between poeciliid‐free poeciliid‐invaded streams. Stream nutrient yields, benthic...
Potential shifts in rainfall driven by climate change are anticipated to affect watershed processes (e.g., soil moisture, runoff, stream flow), yet few model systems exist the tropics test hypotheses about how these may respond shifts. We used a sequence of nine watersheds on Hawaii Island spanning 3000 mm (7500-4500 mm) mean annual (MAR) investigate effects short-term (24-h) and long-term three fecal indicator bacteria (FIB) (enterococci, total coliforms, ). All sample sites were native...
Mangrove forests are the dominant ecosystems on tropical and subtropical coasts, subjected to widespread degradation land conversion, such as aquaculture. To restore mangrove cover, seedlings were planted in coastal fringes abandoned ponds. Most restoration reports focused seedling survival growth rates. However, physiological conditions of seedlings, terms photosynthetic characteristics under field has seldom been studied. from restored ‘planted’ (5- ,8-, 15-, 30-yr old) recolonized 20-yr...
