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...
Coastal wetlands are globally important stores of carbon (C). However, accelerated sea-level rise (SLR), increased saltwater intrusion, and modified freshwater discharge can contribute to the collapse peat marshes, converting coastal peatlands into open water. Applying results from multiple experiments sawgrass (Cladium jamaicense)-dominated brackish water marshes in Florida Everglades, we developed a system-level mechanistic elevation model (EvPEM). We applied simulate net ecosystem C...
Coastal mangrove forests provide numerous ecosystem services, which can be disrupted by natural disturbances, mainly hurricanes. Canopy height (CH) is a key parameter for estimating carbon storage. Airborne Light Detection and Ranging (LiDAR) widely viewed as the most accurate method CH but data are often limited in spatial coverage not readily available rapid impact assessment after hurricane events. Hence, we evaluated use of systematically acquired space-based Synthetic Aperture Radar...
We investigated how mangrove-island micro-elevation (i.e., habitat: center vs edge) affects tree physiology in a scrub mangrove forest of the southeastern Everglades. measured leaf gas exchange rates Rhizophora mangle L. trees monthly during 2019, hypothesizing that CO2 assimilation (Anet) and stomatal conductance (gsw) would decline with increasing water levels salinity, expecting more considerable differences at edges than centers, where physiological stress is greatest. Water varied...
Over the last century, direct human modification has been a major driver of coastal wetland degradation, resulting in widespread losses vegetation and transition to open water. High-resolution satellite imagery is widely available for monitoring changes present-day wetlands; however, understanding rates loss over century depends on use historical panchromatic aerial photographs. In this study, we compared manual image thresholding an automated machine learning (ML) method detecting water...
Abstract Emergent marsh and open water have been identified as alternate stable states in tidal marshes with large, relative differences hydrogeomorphic conditions. In the Florida coastal Everglades, concern has raised regarding loss of non-tidal, peat via dieback emergent vegetation collapse. To aid identification states, our objective was to characterize variability biologic conditions using a field survey long-term monitoring hydrologic geomorphic across range vegetated (emergent,...
Abstract A paradigm in carbon cycling science predicts that sea-level rise will enhance accumulation an apparent negative carbon-climate feedback1,2. However, ecosystems exposed to combinations of stressors and subsidies – such as saltwater intrusion may adapt, transition alternative state, or experience a decline functions, storage, thereby altering their response trajectories environmental changes3,4. Climate change is increasing salinity coastal worldwide yet the effects on ecosystem...
It was during my first ESA meeting in New Orleans, Louisiana, USA, the hot and humid summer of 2018, that I (Anjali Boyd) chose as professional society decided to seek a leadership position within society. Prior attending ESA, had attended numerous national international conferences. However, two things stood out about ESA: diversity ecological disciplines/topics people at conference. By end week (unofficially) joined sections: Student Section Black Ecologists Section. Within few weeks...
