Nonindigenous aquatic species and potential spread after Hurricane Maria Nonindigenous aquatic species and potential spread after Hurricane Maria

This map was created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with Hurricane Maria. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater...

Water temperature in Three Sisters Springs, and water temperature and level in Magnolia Spring: Winter 2014-15 Water temperature in Three Sisters Springs, and water temperature and level in Magnolia Spring: Winter 2014-15

Water level and water temperature from Magnolia Spring were recorded with a level datalogger (HOBO U20-001-01-Ti; Onset Computer Corp., Bourne, MA) set to record every 15 min. The datalogger was attached to a Crystal River National Wildlife Refuge signpost (LAT 28.8913, LONG -82.5925). Data were reported in meters of water depth to the logger and degrees Celcius. Water temperature from...

Grassland priority rankings model for the Western Gulf Coastal Plain of Louisiana Grassland priority rankings model for the Western Gulf Coastal Plain of Louisiana

The dataset includes Land Use/Land Cover types throughout the Chenier Eco-Region in Southwest Louisiana. Using the 2015 National Aerial Imagery Program (NAIP) dataset (1m) as the basemap, E-Cognition image objects were derived from the multiresolution segmentation algorithm at 75 and 250 segments. Attempts to refine the data training methods using E-cognition, to extrapolate automating...

Genetics rayed creekshell Genetics rayed creekshell

This dataset supports the inclusion of Anodontoides radiatus in the genus Strophitus, introducing the binomial Strophitus radiatus. These data also provide strong support for paraphyly in Strophitus and advocate the resurrection of the genus Pseudodontoides to represent the binomials Pseudodontoides connasaugaensis and Pseudodontoides subvexus.

Organic matter decomposition across a coastal wetland landscape in Louisiana, U.S.A. (2014-2015) Organic matter decomposition across a coastal wetland landscape in Louisiana, U.S.A. (2014-2015)

Coastal wetlands store more carbon than most ecosystems globally. However, little is known about the mechanisms that control the loss of organic matter in coastal wetlands at the landscape scale, and how sea-level rise will impact this important ecological function.

eDNAoccupancy eDNAoccupancy

This repository contains the source code and package for the eDNAoccupancy package. This readme file contains the installation instructions for the package. The purpose of the R package is to fit three-level occupancy models. Although designed with eDNA-based observations, the package can be used for any occupancy situation with sampling and sub-sampling.

Cumulative spring discharge and survey effort influence threatened Suwannee moccasinshell, Medionidus walkeri, occupancy and detection Cumulative spring discharge and survey effort influence threatened Suwannee moccasinshell, Medionidus walkeri, occupancy and detection

Freshwater mussels (Unionidae) are among the most imperiled groups of organisms in the world. Unionids are plagued with a lack of basic information regarding species distributions, life history characteristics, and ecological and biological requirements. We assessed the influence of hydrologic factors on the occurrence of the Suwannee Moccasinshell, Medionidus walkeri, a federally...

Will fluctuations in salt marsh - mangrove dominance alter vulnerability of a subtropical wetland to sea-level rise? Will fluctuations in salt marsh - mangrove dominance alter vulnerability of a subtropical wetland to sea-level rise?

To avoid submergence during sea-level rise, coastal wetlands build soil surfaces vertically through accumulation of inorganic sediment and organic matter. At climatic boundaries where mangroves are expanding and replacing salt marsh, wetland capacity to respond to sea-level rise may change. To compare how well mangroves and salt marshes accommodate sea-level rise, we conducted a...

Channel Armor Gap Crevasse (MR-06): 2016 Land-Water Classification Channel Armor Gap Crevasse (MR-06): 2016 Land-Water 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...

Meristic and morphometric data for "Revision of the jawfish genus Lonchopisthus with description of a new Atlantic species (Teleostei: Opistognathidae)" Meristic and morphometric data for "Revision of the jawfish genus Lonchopisthus with description of a new Atlantic species (Teleostei: Opistognathidae)"

Synonymies, diagnoses, descriptions, illustrations, an identification key and meristic frequency tables are provided for all species of Lonchopisthus. Most of the skeletal anatomy of L. higmani is also illustrated. A new jawfish, Lonchopisthus ancistrus n. sp., is described from the Gulf of Mexico and off Honduras based on 21 specimens 41‒89 mm standard length (SL). It differs from other...

Trophic structure of mesopelagic fishes in the Gulf of Mexico revealed by gut content and stable isotope analyses Trophic structure of mesopelagic fishes in the Gulf of Mexico revealed by gut content and stable isotope analyses

Mesopelagic fishes represent an important component of the marine food web due to their global distributions, high abundances and ability to transport organic material throughout a large part of the water column. This study combined stable isotope (SIA) and gut content analyses (GCA) to characterize the trophic structure of mesopelagic fishes in the north central Gulf of Mexico...

Osmoregulatory capacity and muscle water control facing salinity stress of the Amazon fish Astronotus ocellatus (Cichlidae) Osmoregulatory capacity and muscle water control facing salinity stress of the Amazon fish Astronotus ocellatus (Cichlidae)

Scientific tools such as physiological analysis are fundamental to understand invasive species tolerances and responses to different environmental conditions. The Amazon fish Astronotus ocellatus, popularly known as oscar, was introduced worldwide and became invasive in many places. Specimens of A. ocellatus were abruptly submitted to salt stress of 14 and 20 ppt, for 3 and 8 hours to...
