Site fidelity and condition metrics suggest sequential habitat use by early juvenile snook
The common snook Centropomus undecimalis is an estuarine-dependent fish that relies on landward wetlands as nursery habitat. Despite its economic importance, portions of the snook's early life history are poorly understood. We compared habitat use of young-of-the-year (YOY) snook in 2 geomorphic mesohabitats (tidal pond and tidal creek) along an...Brame, Adam B.; McIvor, Carole; Peebles, Ernst B; Hollander, David J.
Assessing the link between coastal urbanization and the quality of nekton habitat in mangrove tidal tributaries
To assess the potential influence of coastal development on habitat quality for estuarine nekton, we characterized body condition and reproduction for common nekton from tidal tributaries classified as undeveloped, industrial, urban or man-made (i.e., mosquito-control ditches). We then evaluated these metrics of nekton performance, along with...Krebs, Justin M.; Bell, Susan S.; McIvor, Carole C.
Nekton community structure varies in response to coastal urbanization near mangrove tidal tributaries
To assess the potential influence of coastal development on estuarine-habitat quality, we characterized land use and the intensity of land development surrounding small tidal tributaries in Tampa Bay. Based on this characterization, we classified tributaries as undeveloped, industrial, urban, or man-made (i.e., mosquito-control ditches). Over one...Krebs, Justin M.; McIvor, Carole C.; Bell, Susan S.
Digital recovery of 19th century surveys in Tampa Bay, Florida: Topographic charts and Public Land Surveys
Recovery of historic data to a digital setting adresses the need for data integration through time, bridging technical gaps and differences. The goal of this study was to evaluate a marsh-to-mangrove conversion spanning 125 years and the implications for present coastal-resource management (Yates and others, 2011; Raabe and others, 2012). The U.S...Raabe, Ellen A.; Roy, Laura C.; McIvor, Carole C.; Gleim, Andrew D.
Tampa Bay coastal wetlands: nineteenth to twentieth century tidal marsh-to-mangrove conversion
Currently, mangroves dominate the tidal wetlands of Tampa Bay, Florida, but an examination of historic navigation charts revealed dominance of tidal marshes with a mangrove fringe in the 1870s. This study's objective was to conduct a new assessment of wetland change in Tampa Bay by digitizing nineteenth century topographic and public land surveys...Raabe, Ellen A.; Roy, Laura C.; McIvor, Carole C.
Microhabitat associations of a semi-terrestrial fish, Kryptolebias marmoratus (Poey 1880) in a mosquito-ditched mangrove forest, west-central Florida
Mangrove rivulus (Kryptolebias marmoratus) is one of the few species of fish that is semi-terrestrial and able to use exposed intertidal and potentially supratidal habitats for prolonged periods of time. Based on previous work demonstrating frequent use of subterranean crab burrows as well as damp leaf litter and logs, we examined the microhabitat...Richards, Travis M.; Krebs, Justin M.; McIvor, Carole C.
Modifications to the bottomless lift net for sampling nekton in tidal mangrove forests
Sampling fishes in vegetated intertidal wetlands is logistically challenging. We modified the 2 ?? 3-m2 bottomless lift net developed for sampling nekton (fish and decapod crustaceans) on the surface of salt marshes for use in tidal mangrove forests with a woody (as opposed to herbaceous) underground root system. As originally designed (Rozas, Mar...McIvor, C.C.; Silverman, N.L.
Defining fish nursery habitats: an application of otolith elemental fingerprinting in Tampa Bay, Florida
Fishing in Tampa Bay enhances the quality of life of the area's residents and visitors. However, people's desire to settle along the Bay's shorelines and tributaries has been detrimental to the very habitat believed to be crucial to prime target fishery species. Common snook (Centropomus undecimalis) and red drum (Sciaenops ocellatus) are part of...Ley, Janet A.; McIvor, Carole C.; Peebles, Ernst B; Rolls, Holly; Cooper, Suzanne T.
Demography and ecology of mangrove diamondback terrapins in a wilderness area of Everglades National Park, Florida, USA
Diamondback Terrapins (Malaclemys terrapin) are distributed in brackish water habitats along the U.S. east coast from Massachusetts to Texas, but many populations may be in decline. Whereas ample morphological, behavioral, and reproductive information has been collected for terrapins living in temperate salt marsh habitats, comparatively little is...Hart, K.M.; McIvor, C.C.
Habitat and hydrology: assessing biological resources of the Suwannee River Estuarine System
The U.S. Geological Survey conducted a pilot integrated-science study during 2002 and 2003 to map, describe, and evaluate benthic and emergent habitats in the Suwannee River Estuary on the Gulf Coast of Florida. Categories of aquatic, emergent, and terrestrial habitats were determined from hyperspectral imagery and integrated with hydrologic data...Raabe, Ellen A.; Edwards, Randy E.; McIvor, Carole C.; Grubbs, Jack W.; Dennis, George D.
Altered mangrove wetlands as habitat for estuarine nekton: are dredged channels and tidal creeks equivalent?
Hasty decisions are often made regarding the restoration of "altered" habitats, when in fact the ecological value of these habitats may be comparable to natural ones. To assess the "value" of altered mangrove-lined habitats for nekton, we sampled for 1 yr within three Tampa Bay wetlands. Species composition, abundance, and spatial distribution of...Krebs, Justin M.; Brame, Adam B.; McIvor, Carole C.
