Root productivity of riverine and scrub mangroves from the Shark River Slough and Taylor Slough, Everglades National Park (FCE LTER), Florida, USA, March 2024 - April 2024
Root productivity of riverine and scrub mangroves in the Florida Everglades: Mangrove root productivity in the shallow root zone (0-45 cm depth) was estimated at all Shark River (SRS-4, SRS-5, SRS-6, SRS-7) and Taylor River (TS/Ph-6, TS/Ph-7) sites in March-April 2024. Root productivity was estimated with the ingrowth core technique using the same sampling protocol previously published for the study area (Castañeda-Moya et al. 2011). Ingrowth cores (10.2 cm diameter x 45 cm length) were made of synthetic material (3 mm mesh) and filled with root-free commercial sphagnum peat moss. This material has similar soil properties (i.e., bulk density, organic matter content, total C and N) as mangrove peat in our study sites as previously reported by Castañeda-Moya et al. (2011). Ingrowth cores were installed in holes made out with a PVC coring device (10.2 cm diameter x 45 cm length). At each site, 8 ingrowth cores were deployed vertically into the soil to a depth of 45 cm and retrieved one year later (March-April 2024). After collection, ingrowth cores were processed individually and initially rinsed with water through a 1-mm screen mesh to remove soil particles and peat moss material. Live roots were separated manually based on their buoyancy, turgor, and color (Castañeda-Moya et al. 2011; Cormier et al. 2015; Medina-Calderon et al. 2021). Live roots were further sorted into three size diameter classes including fine (<2 mm), small (2-5 mm), and coarse (5-20 mm). Roots greater than 20 mm in diameter were not included in this study due to sampling limitations (i.e., core area). All root samples were oven-dried at 60°C to a constant mass and weighed. Root growth within each ingrowth core following one year of incubation was used to estimate annual root productivity (g m⁻² yr⁻¹) in the shallow root zone across all mangrove sites. All data collection and processing were funded by FCE-LTER. Data collection is complete. References: Castañeda-Moya, E., R.R. Twilley, V.H. Rivera-
Water Temperature measured at Shark River, Everglades National Park (FCE) from October 2007 to August 2008
American alligators (Alligator mississippiensis) are top predators in the Florida Coastal Everglades (FCE), but their movement patterns and role in the ecosystem are largely unknown. Proposed restoration and management efforts in the Everglades are likely to influence both alligator movements and the spatiotemporal patterns of their effects on ecosystem and community dynamics, making studies of the factors influencing alligator movements important at this time. In October 2007, we initiated a study of alligators in the Shark River Slough of Everglades National Park using two tracking techniques that have yet to be used on crocodilians: GPS tracking and passive acoustic telemetry. GPS units attached to two alligators have provided 120 positions over a two month period while acoustic transmitters attached to 12 alligators have been detected 34,000 times on an array of 8 monitoring stations within the river system. GPS positions are more accurate than acoustic monitoring and can provide data over the entire range an alligator might move, but acoustic transmitters provide more temporally detailed information on movements within a monitoring array and over a longer duration (potentially years rather than months). Our preliminary results show that alligators may remain in localized areas for weeks at a time, but make long-distance moves from the mouth of the river system to the marsh-mangrove ecotone and likely into the marsh. In general, most alligators moved upstream as freshwater inputs decreased, but some individuals remained near the river mouth even when salinities were high. Ultimately, by characterizing alligator movements in relation to spatiotemporal variation in environmental factors we will be able to predict how alligator distributions and populations will respond to planned increases in freshwater flow. Furthermore, movement data combined with dietary and stable isotopic studies may shed light on the possible role of alligators in the redistribution of nutri
Water Temperature, Salinity and other physical measurements taken at Shark River, Everglades National Park (FCE LTER) from February 2010 to March 2014
In early 2010 we established three new permanent water quality monitoring stations in the Shark River Estuary. These stations expanded FCE's spatial coverage in terms of salinity and also established the first continuous dissolved oxygen monitoring in the estuary.
Water Temperature measured at Shark River, Everglades National Park (FCE) from July 2007 to June 2011
Between 2007 and 2011 we placed HOBO continuous water temperature loggers at 17 locations in the Shark River Estuary for various lengths of times. These stations expanded FCE's spatial coverage in terms of temperature monitoring in the estuary.
Community structure of aquatic vertebrates and macroinvertebrates in relation to hydrologic variables in the Shark River Slough, Everglades National Park, Florida USA: Ongoing since 2012
The purpose of this project is to characterize the community structure of aquatic fauna (macroinvertebrates and fishes) and floating mats (including periphyton) across the heterogenous landscape of the NE Shark River Slough in Everglades NP. The community structure (abundance, biomass, and species composition) of floating mat, emergent vascular plants, fishes, and macroinvertebrates, and the spatial distribution of the latter in relation to hydrology, are among the key performance measures targeted for monitoring. The aim of our study is to provide a baseline characterization of these parameters so that the impact of future management activities (e.g., Modified Water Deliveries and Comprehensive Everglades Restoration Plan) can be assessed. The study area is sampled during the late wet season (September through November) to capture data when all sites are innundated with water and aquatic animal standing stocks are typically at their maximum. We document landscape-scale patterns in the NE Shark River Slough from this comprehensive sampling.
Inventory of soil prokaryotic microbiome (via 16S based on rRNA gene amplicons) in freshwater and brackish water marshes following saltwater intrusion along Shark River Slough boundary, Everglades National Park (FCE LTER), Florida, USA, September 2018
Global sea-level rise is transforming coastal ecosystems, especially freshwater wetlands, in part due to increased episodic or chronic saltwater exposure, leading to shifts in microbial communities and related ecological services. Soil prokaryotes play a fundamental role in regulating important biogeochemical processes in coastal wetland ecosystem. Yet, it is still difficult to predict how soil prokaryotic communities respond to the saltwater exposure because of poorly understood prokaryotic sensitivity within complex wetland soil microbial communities, as well as the high heterogeneity of wetland soils and saltwater exposure. To address this, a four-year experimental simulation of saltwater intrusion in a pristine freshwater site and a previously saltwater-impacted site was conducted. The saltwater addition started in October 2014 on a monthly basis and continued through October 2018. The dataset contains amplicon sequencing date of 16S rRNA gene obtained from saltwater-exposed soils and unmanipulated native soils in both sites (collected in September 2018). The 2018 data are published in Zhao et al. 2023. A detailed list of sequence data and their accession numbers in GenBank is provided, and data collection is complete.

Inventory of soil prokaryotic and fungal microbiome (via 16S rRNA gene amplicons and ITS sequencing) from Shark River Slough and Taylor Slough, Everglades National Park (FCE LTER), Florida, USA, February 2019 - October 2020
Global sea-level rise is transforming coastal ecosystems, especially freshwater wetlands, in part due to increased saltwater exposure, leading to change in soil microbial communities and many important biogeochemical processes. Given the high spatial and temporal heterogeneity in coastal wetlands, especially in tropical or subtropical climates characterized by seasonal temperature, precipitation, and tidal fluctuations, it remains unclear which environmental factors influence the compositions of soil microbial communities in wetlands affected by varying degrees of sea-water intrusion. To address this, a two-year survey was conducted on microbial community structure in submerged surface soils from 14 wetland sites across the Florida Everglades, representing three major ecosystem types, i.e. freshwater marshes, mangrove forests, and seagrass meadows. Bulk surface soil samples of each site were collected from February 2019 to October 2020 to cover dry and wet seasons. In addition to bulk soil samples, soil cores were collected from each site in August 2020 to assess vertical gradients of microbial communities. The dataset contains amplicon sequencing data of 16S rRNA gene (both bulk soil and soil cores) and ITS gene (only the bulk soil). The 2019 to 2020 data are published in Zhao et al. 2023.

An updated survey of freshwater fishes within Letchworth State Park and surrounding areas of the Genesee River
<p>The goal of this study was to gather information about freshwater fishes in Letchworth State Park (42.615275°N, -77.992825°W), a portion of New York State-owned land located in the Genesee River watershed that lacks known data about its fish diversity. The fish collection took place between 2017 and 2019 in the Genesse River upstream and downstream of the falls using gill, hoop, and seine netting and electrofishing. This was the first attempt at a comprehensive survey of this portion of the river, which allowed for a baseline to be established regarding fish biodiversity in the region. The updated total number of species found in this portion of the Genesee River was 25, 22 of which were newly identified downstream of the falls, in Letchworth State Park. We encourage further collection and continuation of this survey with consistent sampling techniques to promote ongoing field surveys and fish collection that inform freshwater fish diversity in stream ecosystems across the globe.</p>
