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.
Nutrient data from the Peat Collapse-Saltwater Intrusion Field Experiment from brackish and freshwater sites within Everglades National Park, Florida (FCE LTER), collected from October 2014 to September 2016
With sea level rise increasing, saltwater intrusion into low-lying coastal wetlands is likely to occur. We simulated saltwater intrusion into an Everglades marsh through monthly additions of elevated salinity water. Monthly porewater nutrients were taken at 15 cm depth from a brackish and a freshwater marsh. Porewater physicochemistry was measured 24 hours after dosing. Collection occurred from Oct 2014 - Sep 2016. The collected water was then analyzed for temperature, conductivity, salinity, pH, alkalinity, chloride, DOC, NH4, SO4, TDN, SRP, TDP, and sulfide. These data are published in Wilson, B.J., Servais, S., Mazzei, V., Davis, S.E., Kelly, S., Gaiser, E., Kominoski, J.S., Richards, J., Rudnick, D., Sklar, F., Stachelek, J., and Troxler, T.G. Salinity pulses interact with seasonal dry-down to increase ecosystem carbon loss in marshes of the Florida Everglades. 2018. Ecological Applications 28:2092-2018.

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.
Decomposition rates of four litter types along coastal gradients in Everglades National Park (FCE LTER), Florida, USA: 2020-2021
Leaf litter, of variable quality, was deployed along freshwater-to-marine gradients to investigate the drivers of litter breakdown in the Florida Coastal Everglades. Sea-level rise provides both stressors and subsidies to microbial communities that break down litter, and is also causing shifts in the vegetation producing litter, changing the initial quality of litter being deposited in coastal wetlands. The goal of this project was to understand the complex relationship between marine stressors and subsidies, by performing a reciprocal transplant of litter. Litter from each major vegetation species along the freshwater to marine gradient were deployed at sites in freshwater, the ecotone, mangrove forest, and in Florida Bay. This reciprocal transplant of different qualities of leaf litter into novel environments across a gradient of salinity and phosphorus will give insights into the effects of litter carbon quality, littery chemistry, microbial productivity of decomposers, and environmental chemistry as drivers of the breakdown of leaf litter.
A database of soil type and soil depth across Everglades National Park, Florida, USA
This dataset contains record of soil type and soil depth across Everglades National Park. This data was obtained through published literature, unpublished field data, and inter-agency collaboration. Data come from either soil cores to bedrock or refusal (as specified by data source), cores that did not reach bedrock, a soil probe to determine depth, or the depth of installed surface elevation tables. Soil type was classified either along a gradient of organic matter content when data was available: mineral (<40%), intermediate (40-70%), or organic (<70%). When data on organic matter content wasn’t available but qualitative descriptions of soil type were, the type unit of soil was classified as either organic or mineral based on the descriptive lithology. When lithologic descriptions were provided and indicated the soil profile was not entirely one soil type (e.g. peat), depth of peat within core was recorded. When data source had specific coordinates, those coordinates were used. For older studies that only provided a figure showing the location of each estimate at a broad scale, location was estimated by georeferencing the figure in ArcMap, and dropping a point at each location. Records were cross-referenced with a recent vegetation map developed by the National Park Service in order to obtained vegetation community at each location (Ruiz et al. 2017).
Fatty acid data among habitats and between seasons in Everglades National Park, Florida, USA, 2018-2019
Fatty acid profiles to represent the aquatic food web of the freshwater habitats from wet and dry seasons of the Everglades, Florida, USA. This dataset provides fatty acid profiles for a range of food-web members from basal resources (vascular plants, benthic flocculent matter, periphyton), aquatic invertebrates, amphibians, and fishes (including non-native and invasive species). Each sample is a composite of six individuals on average. Samples were collected from multiple habitats across sites in Shark River Slough and Taylor Slough in the wet (2018) and dry (2019) seasons. In some cases, in order to have enough tissue to make a composite sample, the composite was made at a higher level then at a habitat within a site. For example, some composites are from the same slough-season-habitat and combined from multiple sites. The goal was to capture as much of the aquatic food web in the wet and dry seasons as possible to build fatty-acid derived food-web snap shots, not necessarily to quantify variation at various levels of different factors (e.g., habitat and site). However, common species are relatively well replicated among factor levels. Data collection is complete.
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. A detailed list of sequence data and their accession numbers in GenBank is provided, and data collection is complete. This data package is an inventory of sequence read archive (SRA) entries available through GenBank BioProject PRJNA804243 (https://www.ncbi.nlm.nih.gov/bioproject/?term=PRJNA804243), PRJNA804246 (https://www.ncbi.nlm.nih.gov/bioproject/?term=PRJNA804246), and PRJNA804228 (https://www.ncbi.nlm.nih.gov/bioproject/?term=PRJNA804228).

Leaf litter, soil, and periphyton gene expression along freshwater to marine gradients in Everglades National Park (FCE LTER), Florida, USA, January 2021 and April 2021
We collected leaf litter, periphyton, and soil along freshwater to marine gradients at SRS-2, SRS-4, SRS-6, TS/PH-2, TS/Ph-3, TS/Ph-7a, and TS/Ph-10. Samples were collected in January and April of 2021 to understand how microbial communities respond to and influence the breakdown of organic matter along freshwater to marine transects. Data collection for this project is complete. For each site and litter pair we collected a subset of 2-3 g wet mass of litter, a grab sample of soil, and a grab sample of periphyton for each site. All subsamples were preserved at -20°C until extraction, which took place up to a year after initial collection. Samples were sent to Novogene (Novogene Co. Ltd., Beijing, China) for the total RNA extraction followed by metatranscriptome sequencing. We selected n = 12 genes/gene families encoding for focal enzymes to investigate which are important to the breakdown of organic matter: Dioxygenases (associated with aerobic respiration), Sulfatases (associated with the release of sulfates from complex molecules), sulfite reductases (associated with sulfite reduction), methyl coenzyme M reductase and formylmethanofuran (associated with methanogenesis), nitrite reductases (associated with nitrite reduction), cellobiosidase, glucosidase, and xylosidase (associated with cellulose breakdown), phenol oxidase (associated with lignin breakdown), acid phosphatase (associated with phosphate acquisition in acidic environments), and alkaline phosphatase (associated with phosphate acquisition in basic environments). For each gene/family of interest, we searched all annotated transcripts for all entries corresponding to that gene/family and combined all values for a total expression. We selected n = 6 monophyletic microbial functional groups, representing sulfate reducers, sulfate oxidizers, methane oxidizers, methanogens, nitrite oxidizers, and ammonia oxidizers associated with sulfate and methane cycling. We filtered all annotated transcripts for all specie
Holocene insect fossil data for Indian Peaks Wilderness and Rocky Mountain National Park, 1985 and 1993.
Insect fossil assemblages were analyzed from the Indian Peaks Wilderness and Rocky Mountain National Park. Assemblages span the last 10,000 years revealing climate change and the response of both insects and vegetation in the montane to upper subalpine zones. The Longs Peak Inn Bog site (LPIB) yielded insect assemblages ranging in age from recent to 3500 yr BP. This insect fossil record suggests climatic cooling at about 1800 yr BP and between 250 and 300 yr BP (AD 1700-1850). The bog may experience colder microclimates than the surrounding forests, yielding insect assemblages reflective of the colder, local microclimate. Also, alpine and upper subalpine insects may have been washed into the catchment basin of the bog from nearby slopes. Assemblages from four additional Front Range sites suggested a climatic optimum between 9000 and 7000 BP. Faunal evidence indicates a tree-limit decline at 4500 BP. Declining forest-tundra insect ratios, combined with the conifer macrofossil record, suggest a climatic deterioration from 4500 to 3100 BP followed by a rapid amelioration, from 3000 to 2000 BP. A gradual decline in the forest-tundra ratios occurred after 2000 BP, reaching 1:1 ratios at or before 1000 BP.
The use of ancient DNA from sediment as a viable measure of Quaternary biodiversity within the Brecon Beacons National Park: a preliminary study
<p>Contains 3 files.</p> <ul> <li>One spreadsheet containing processed sequences -SM1_results_spreadsheets</li> <li>The other two containing Read 1 and Read 2 of the raw sequences (fastq).</li> </ul> <p>Abstract</p> <p>A major challenge in the study of Quaternary environments is the variable preservation of paleoenvironmental evidence at many locations. Using ancient DNA from sediment cores (sedaDNA) allows the reconstruction of past biodiversity patterns at locations where traditional techniques often only reveal a partial picture. To test the feasibility of this approach, we analysed a sediment core from a peat bog, Traeth Mawr, in the Brecon Beacons National Park. Plant DNA was extracted and subjected to DNA metabarcoding, combining the use of universal PCR primers with Next-Generation Sequencing, to analyse a 7-143bp segment of the chloroplast <em>trn</em>L gene in five temporally separated sections of the core. Pollen analyses, from sections of the core, provide a comparison between the sedaDNA results and more traditional methods for studying the paleoenvironment. Partial reconstruction of past environmental variation was possible with the recovery of 113,682 DNA sequences representing six plant families, adding complementary results to traditional pollen analysis. This study is the first in the UK to successfully report the sequencing of ancient plant DNA from terrestrial sediments (currently a peat bog) using a DNA metabarcoding approach and exemplifies a promising area of research for addressing a range of questions about Quaternary environmental change.</p>
