Drivers of algal abundance in edge of ranch and internal ditches on a south-central Florida ranch, 2023.
Although algae blooms are historically common in Lake Okeechobee and surrounding waterways, blooms in recent years have covered much of the lake’s surface and have contained toxin-producing groups of algae, rendering them harmful algae blooms (HABs). South Florida Water Management District and other entities have taken strides to manage interior waterways before nutrient-rich freshwater reaches downstream estuaries along the coasts. Because ranching is the largest land use by area in the Lake Okeechobee watershed, ranches may be able to improve HAB mitigation strategies by holding water, and therefore nutrients, in private wetlands and ditches. Our study assesses water quality within 19 ditch sites on Buck Island Ranch (BIR), a working cattle ranch in south-central Florida. Sites were sampled monthly for nutrient concentration, temperature, conductivity, pH, dissolved oxygen, turbidity, site characteristics, and chlorophyll a concentration as an indicator of algal biomass. We analyzed relationships between chlorophyll a, nutrient concentrations, and biophysical parameters to establish possible drivers of algal abundance in the ditches. We expected higher chlorophyll a concentrations during periods of higher nutrient concentrations and higher light availability. Higher chlorophyll a concentrations were also expected in the internal ranch ditches, as these sites bordered pastures that have been historically fertilized. Results suggested that ditch location, total nitrogen and total phosphorus explained the most variations of chlorophyll a concentrations in ranch ditches. Our research indicates that nutrient fluxes contribute to general algae growth within cattle ranches in the Lake Okeechobee watershed, potentially contributing to downstream water quality affects. Future research could demonstrate the effects of ranch management on specific types of algae blooms, distinguishing between diatoms, harmful algae, and other algal groups.
Survival and growth of south Florida slash pines in four seasonal ponds at Archbold Biological Station, 1992-2001
These data summarize survival and plant size (height, basal diameter) for south Florida slash pine (Pinus elliottii var. densa) in four seasonal ponds at Archbold Biological Station from 1992-2001. Plants were seedlings, saplings, or small trees. The seasonal ponds were favorable for growth (0.1-0.6 m in height per year) and annual survival (usually over 80%) in the absence of fire or major flooding events. Flooding episodes during most of the study ranged from 3-11 months each year. Mortality increased with flooding intensity and decreased with plant size. Growth rates were not affected by flooding. Near the end of the study, two fires killed 72% of these pines (low intensity, prescribed) and 100% of these pines (intense wildfire). The study suggests that most seasonal ponds do not support large south Florida slash pine individuals despite generally favorable conditions, because of periodic flooding and fire.
Demography of the rare herb, Polygala lewtonii (Polygalaceae), with multiple fires on the Lake Wales Ridge in south-central Florida from 2001-2017 (ongoing)
Demographic data on 5,060 individually marked plants of the endemic State and federally listed Polygala lewtonii (Lewton's milkwort; Polygalaceae) were collected from December 2001 to December 2017 at the Lake Wales Ridge National Wildlife Refuge Carter Creek in south-central Florida, USA. Data collection is still ongoing. In 220 permanent 25 cm radius circular plots, plants were marked with plastic toothpicks and wire stake flags with a unique identification number. Data collection occurred quarterly with survival and recruitment recorded in March, June, September and December and more detailed measures of size and fecundity taken in March. This species is amphicarphic with both showy-open flowers produced in spring (chasmogamy) and closed, self-pollinating flowers both above- and belowground produced in late summer (cleistogamy). Therefore, our fecundity data are based only on chasmogamy. This dataset also captures post-fire mortality and recruitment events following four prescribed burns.

DOC fluxes calculated from DOC concentrations measured monthly at SRS5 (LT_ND_Grahl_002) and tidally filtered discharge measured at USGS gage 252230081021300. These data are published in Long-term environmental drivers of DOC fluxes: Linkages between management, hydrology and climate in a subtropical coastal estuary (DOI 10.1016/j.ecss.2016.09.017)
Sediment accumulation rate data aggregated from publications describing research conducted in South Florida on coastal wetlands prior to 2022
Wetland sediment accumulation rate data were harvested from publications describing research conducted in the Southeast Saline Everglades, Northeast Florida Bay, the Lower Florida Keys, Southwest Everglades National Park, Ten Thousand Island National Wildlife Refuge, and Rookery Bay National Estuarine Research Reserve. The data were organized into three categories based on the method by which they were calculated: lump sum, core section interval, Sediment Elevation Table Marker Horizon. The data were assembled by Dr. Randall W. Parkinson as part of his research on the resiliency of coastal wetlands to accelerating sea-level rise.

Monitoring of vegetation and fire in Florida scrub, flatwoods, and wet prairie in south-central Florida from 1977-2015
This data package is comprised of three datasets all pertaining to the impacts of prescribed fires and wildfires on vegetation at 11 permanent transect sites over nearly four decades at Archbold Biological Station (ABS) in south-central Florida. Data were collected between 1977 to 2015 in wet prairies, flatwoods, oak scrub, rosemary scrub, and hickory scrub. The first dataset, cover_data, contains year and month of sampling at a given transect site, the vegetation association type, burn unit, and the percentage cover data for sampled species and bare ground. The second dataset, fire_occurrence, includes the dates of each fire that impacted each transect site, the burn unit of the transect, and the percentage of transect burned. The third dataset, species_information, includes the scientific name, common name, plant family, and nativity of each sampled species. A fourth unpublished dataset provides the GPS locations for all the aluminum posts that mark each of the 11 transects. These data are available from the Archbold data manager. Below we summarize the setup and data collected for each dataset. Cover_data: We determined the percentage cover (i.e., dominance) of each encountered species at 11 vegetation stands including two wet prairies (WS20, WS21), three flatwoods (WS30, WS42, WSP1), and six Florida scrub associations including four oak scrubs (WS26, WSP2, WS24, WS25, the latter two include areas of rosemary scrub), a rosemary scrub (WS27), and a hickory scrub (WS29). Each stand was sampled at selected times, ranging from five to as many as 12 repeated samplings, during the 38-yr period beginning in 1977 and continuing to 2015. Stands were sampled during January (mid-way during the winter dry season) except for sampling four stands in May 1977 and eight stands in July 1977 to document short-term 4-month and 6-month vegetation recovery following the initial January 1977 prescription burn. At each permanently marked transect site, we sampled 200 m using two parall
Freshwater Subtropical Ridge and Slough Wetland Metabolism, South Florida, USA: 2014-2016
How climate and habitat drive variation in aquatic metabolism in wetlands remains uncertain. To quantify differences in seasonal aquatic metabolism among wetlands, we estimated aquatic ecosystem metabolism (gross primary productivity, GPP; ecosystem respiration, ER; net aquatic productivity, NAP) in subtropical ridge and slough wetlands of the Florida Everglades from more than 2 years of continuously measured water column dissolved oxygen (DO), photosynthetically active radiation (PAR), water temperature, and water depth. GPP and ER were modeled from light, temperature, and water depth using non-linear minimization and maximum likelihood. Reaeration rates were estimated from wind speed. Dissolved oxygen was below saturation at all sites during both wet and dry seasons. Water depth interacted with vegetation to influence PAR, water temperature, and spatiotemporal patterns in aquatic metabolism. GPP and ER were highest at the slough with lowest submerged aquatic vegetation (low-SAV slough), intermediate in the sawgrass (Cladium jamaicense) ridge site, and lowest at the slough with lowest submerged aquatic vegetation (high-SAV slough). ER was strongly positively correlated with GPP at the sawgrass ridge and low-SAV slough sites. GPP increased with water temperature and PAR across all habitat types, whereas ER decreased (more respiration) with water temperature and PAR. NAP was negatively correlated with water temperature and positively correlated with PAR, suggesting that ER was more sensitive than GPP to water temperature. Aquatic metabolism was largely net heterotrophic in all wetlands, and high-SAV appeared to buffer seasonal variation in PAR and water temperatures that drive NAP in subtropical wetlands. Our results suggest that aquatic ecosystem metabolism in wetlands with seasonal hydrology is sensitive to changes in water depth and vegetation density that influence temperature and light. Expanding our understanding of how metabolic processes and carbon cycling in
American crocodile captures in South Florida
<p>The federally threatened American crocodile (<i>Crocodylus acutus</i>) is a flagship species and ecological indicator of hydrologic restoration in the Florida Everglades. we conducted a long-term capture-recapture study on the South Florida population of American crocodiles from 1978 to 2015 to evaluate the effects of restoration efforts to restore historic hydrologic conditions. The study produced 10,040 crocodile capture events of 9,865 individuals and more than 90% of captures were of hatchlings. Body condition and growth rates of crocodiles were highly age-structured with younger crocodiles presenting with the poorest body condition and highest growth rates. Average body condition was 2.14±0.35 SD throughout South Florida. Crocodiles exposed to hypersaline conditions (> 40 psu) during the dry season maintained lower body condition scores and reduced growth rate by 13% after one year, by 24% after five years, and by 29% after ten years. Estimated hatchling survival for the South Florida population was 25% increasing with ontogeny and reaching near 90% survival at year six. Hatchling survival was 34% in NE Florida Bay relative to a 69% hatchling survival at Crocodile Lake National Wildlife Refuge and 53% in Flamingo area of Everglades National Park. Hypersaline conditions affected survival, growth and body condition and was most pronounced in NE Florida Bay, where the hydrologic conditions have been most disturbed. The American crocodile, a long-lived animal, with relatively slow growth rate provides an excellent model system to measure the effects of altered hydropatterns in the Everglades landscape. Restoration efforts targeted toward returning freshwater flow and salinity targets of < 20 psu to reflect a more historic state in NE Florida Bay will ensure improved health of the Everglades and illustrates the need for continued long-term monitoring projects to assess system-wide success.</p> <p> </p>
