Faunal and vegetation monitoring in response to harbor dredging in Port of Miami Faunal and vegetation monitoring in response to harbor dredging in Port of Miami
Seagrasses are highly productive ecosystems. A before-after-control-impact (BACI) design was used to examine effects of dredging on seagrasses and the animals that inhabit them. The control site North Biscayne Bay (NBB) and impacted site Port of Miami (POM) had seagrass densities decreased during the before, Fish and Invertebrate Assessment Network (FIAN) 2006-2011 and after, Faunal...
Manatee environmental DNA data, and associated attributes, collected from the United States, Cuba, and Cameroon, from 2013-2015 Manatee environmental DNA data, and associated attributes, collected from the United States, Cuba, and Cameroon, from 2013-2015
Environmental DNA (eDNA) detection is a rapidly expanding technique used to non-invasively detect cryptic, low density, or logistically difficult-to-study species, such as imperiled manatees. Genetic material shed into the environment through tissue and body fluids is concentrated from water samples and analyzed for the presence of targeted eDNA. To help delineate manatee habitat ranges...
Salt marsh carbon dynamics under altered hydrologic regimes and elevated CO2 conditions, Louisiana, USA (2014-2015) Salt marsh carbon dynamics under altered hydrologic regimes and elevated CO2 conditions, Louisiana, USA (2014-2015)
Plant-mediated processes are often important in determining carbon cycling and storage in ecosystems. With climate-induced changes in the environment, plant-associated processes may also shift. Salt marshes in particular are useful systems to investigate plant-mediated carbon cycling, as these systems experience both sea-level rise and increased carbon dioxide concentrations due to...
Non-native fishes of the central Indian River Lagoon Non-native fishes of the central Indian River Lagoon
We provide a comprehensive review of the status of non-native fishes in the central Indian River Lagoon (from Cape Canaveral to Grant-Valkaria, east of I-95) through literature review and field surveys. Historical records exist for 17 taxa (15 species, one hybrid, one species complex). We found historical records for one additional species and collected one species in our field survey...
Early growth interactions between a mangrove and an herbaceous salt marsh species are not affected by elevated CO2 or drought, Louisiana saltmarsh, 2015 Early growth interactions between a mangrove and an herbaceous salt marsh species are not affected by elevated CO2 or drought, Louisiana saltmarsh, 2015
In recent decades the encroachment of woody mangrove species into herbaceous marshes has been documented along the U.S. northern Gulf of Mexico coast. These species shifts have been attributed primarily to rising sea levels and warming winter temperatures, but the role of elevated atmospheric carbon dioxide (CO2) and water availability may become more prominent drivers of species...
Exotic invasive giant apple snails (Pomacea maculata) will depredate eggs of frog and toad species of the Southeastern United States Exotic invasive giant apple snails (Pomacea maculata) will depredate eggs of frog and toad species of the Southeastern United States
Frog eggs of three different species were presented to giant apple snails (Pomacea maculata) to determine if the snails will eat the eggs. There were four treatments: control-eggs in water only; control with lettuce-eggs in water and lettuce which was used as snail food; snail-eggs in water with snail; and snail with lettuce-eggs in water with snails and lettuce (as an alternative food...
Brady Canal hydrologic restoration (TE-28): 2016 habitat classification Brady Canal hydrologic restoration (TE-28): 2016 habitat classification
The Louisiana State Legislature created Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed persuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...
Data for sediment application to cypress and tupelo seedlings in greenhouse study - 2016 Data for sediment application to cypress and tupelo seedlings in greenhouse study - 2016
The decline of Taxodium distichum, bald cypress, forests along the Gulf Coast of North America is partly due to elevation loss and subsequent flooding. In many coastal wetlands, a common approach for coastal restoration is to rebuild elevation through the application of dredge spoil, but this technique has not been used widely in coastal forests due to concerns of negatively impacting...
Land area change in Coastal Louisiana (1932 to 2016) - persistent land change spatial data Land area change in Coastal Louisiana (1932 to 2016) - persistent land change spatial data
Coastal Louisiana wetlands are one of the most critically threatened environments in the United States. These wetlands are in peril because Louisiana currently experiences greater coastal wetland loss than all other States in the contiguous United States combined. The analyses of landscape change presented here have utilized historical surveys, aerial, and satellite data to quantify...
Evaluating GPS biologging technology for studying spatial ecology of large constricting snakes, Everglades National Park, 2015-2017 Evaluating GPS biologging technology for studying spatial ecology of large constricting snakes, Everglades National Park, 2015-2017
This dataset contains four comma-delimited files collected to evaluate the utility of GPS biologging tags for studying the spatial ecology of large constricting snakes. The first file contains the dates that five Burmese pythons were deployed for tracking in Everglades National Park, FL. The second file contains the data from each of those five python GPS tags with all of the attempted...
Phragmites australis maps and change, Delta National Wildlife Refuge, Louisiana (2011, 2013, 2016) Phragmites australis maps and change, Delta National Wildlife Refuge, Louisiana (2011, 2013, 2016)
This U.S. Geological Survey Data Release includes maps of Phragmites australis coverage within the Delta National Wildlife Refuge (NWR), located on the eastern half of the Mississippi River Delta in south Louisiana, for 2011, 2013 and 2016. While the objective of this mapping effort was to map the presence of P. australis, the map also includes coverage of water and non-P.australis land...
Salinity tolerance of non-native suckermouth armoured catfish (Loricariidae: Pterygoplichthys sp.) from Kerala, India Salinity tolerance of non-native suckermouth armoured catfish (Loricariidae: Pterygoplichthys sp.) from Kerala, India
Loricariid catfish of the genus Pterygoplichthys have been introduced in many localities around the world. They are freshwater fishes, but may also use low-salinity habitats such as estuaries for feeding or dispersal. Here we report results of a field survey and salinity-tolerance trials for a population of Pterygoplichthys sp. collected in Kerala, India. In both chronic and acute...
