Diatom blooms play a central role in supporting foodwebs and sequestering biogenic carbon to depth. Oceanic conditions set bloom initiation, whereas both environmental ecological factors determine magnitude longevity. Our study reveals another fundamental determinant of dynamics. A diatom spring offshore New Zealand waters was likely terminated by iron limitation, even though diatoms consumed <1/3 the mixed‐layer dissolved inventory. Thus, duration were primarily competition for between...
Abstract Site fidelity, space use, and dispersal are commonly estimated with acoustic telemetry (AT) to help inform management conservation. These behaviors can change age, habitat environmental conditions our ability accurately estimate them is affected by a study’s inference power (design components that affect how detection data represents species’ movements). Red snapper ( Lutjanus campechanus ) have been extensively studied AT over range of time periods regions, although primarily at...
The demands of future large-scale combat operations may require medics and corpsmen to increasingly perform expectant casualty care (ECC). However, no detailed guidelines currently exist for providing ECC within military medicine. To guide the development education training advance team both non-medics, an in-depth understanding is first needed regarding caregivers' experiences in recent conflicts as well perceived gaps. Therefore, this study explored physicians investigated their...
Abstract The recent introduction of invasive Indo‐Pacific lionfish species (Red Lionfish Pterois volitans and Devil Firefish P. miles , hereafter collectively referred to as lionfish) into the western Atlantic Ocean has been extensively documented in both scientific literature media. Nevertheless, much information synthesized obtained via diver‐based surveys there is likely a depth‐related bias understanding temporal spatial dynamics invasion. Accordingly, we examined data from broadscale...
Abstract We conducted a comprehensive examination of long‐term (10+ years) fisheries‐independent data to characterize the spatial and temporal patterns habitat selection recruitment juvenile gags Mycteroperca microlepis in four eastern Gulf Mexico estuaries Florida: Apalachicola Bay, Cedar Key, Tampa Charlotte Harbor. Results from generalized linear modeling suitability analyses indicated that selected euhaline or polyhaline habitats with sloping bottoms extensive coverage submerged aquatic...
Abstract Increasingly restrictive management regulations have greatly reduced the utility of fishery‐dependent data for characterizing temporal changes in abundance managed fish populations, so fishery‐independent are becoming more important accurate assessment stock status. A notable downside to is high cost conducting surveys, and efforts maximize survey efficiency critical given ongoing reductions agency funding. We conducted a pilot study explore classifying side‐scan‐sonar mapping...
Abstract Objective Since 2010, three spatially disjunct reef fish video surveys have provided fishery‐independent data critical to the assessment and management of fishes in Gulf Mexico. Although analytical approaches recently been developed integrate from these into a single measure relative abundance size composition, more parsimonious approach would be survey efforts under Gulf‐wide design. Accordingly, we conducted retrospective analysis historical video‐ habitat‐mapping develop novel...
Abstract We developed a multiple‐gear survey (183‐m haul seine and 6.1‐m otter trawl) that was designed to supplement long‐term, fishery‐independent data on age‐0 Gags Mycteroperca microlepis in Apalachicola Bay, Tampa Charlotte Harbor, Florida. The supplemental design specifically considered juvenile Gag recruitment ecology thus targeted the deep, polyhaline seagrass habitats are utilized by yet infrequently sampled. It also expanded spatial coverage of ongoing surveys include two unsampled...
The eastern Gulf of Mexico continental shelf (approximately 144,000 km2), while dominated by unconsolidated sediments, contains diverse hard bottom habitats critical to economically important reef fishes. Although high-resolution mapping exists for several well-known features (e.g. Florida Middle Grounds, Sticky Grounds), the majority remains unmapped. Through efforts conducted in support fisheries independent resource surveys, were identified and classified from 4208 randomly distributed,...
Three surveys in the eastern Gulf of Mexico use baited remote underwater video systems to assess changes abundance reef fishes: National Marine Fisheries Service (NMFS) Southeast Area and Monitoring Assessment Program Reef Fish Video Survey, NMFS Panama City (Florida) survey, Wildlife Research Institute Florida Conservation Commission survey. These similar sampling gear video-processing protocols, but they vary spatial extent habitats sampled. Each survey has been used individually produce...
Abstract Estuarine‐dependent Gray Snapper Lutjanus griseus support extensive recreational fisheries in estuarine and coastal waters throughout the eastern Gulf of Mexico. Multiyear fisheries‐independent monitoring data collected three Florida estuaries can be used to estimate strength juvenile recruitment, which has been critical assessments other fish populations. Earlier evaluation these indicated that inhabit polyhaline seagrass beds, are underrepresented ongoing efforts. During this...
Abstract Fishery‐independent data are important for the effective management of reef fishes in eastern Gulf Mexico. Proper characterization selectivity, or effectiveness each type sampling gear capturing a species size‐class, is essential to ensure that assessment models treat various sources appropriately. In this study, we analyzed fishery‐independent was collected using stereo‐baited remote underwater video (S‐BRUV) arrays, chevron traps (TRAP), and two types hooked (repetitive timed‐drop...
Florida's west coast is a 170,000 km2 bedrock shelf (WFS) comprised of north-south discontinuous carbonate outcroppings extending more than 200 km from the intertidal zone to depth m. These outcrops support diverse benthic communities, which contribute multi-billion dollar recreational and commercial fishing industry, yet only about 5% their extent has been studied in detail. Benthic communities shift over 6.5° geographic range, but locations these shifts are not well-defined. Previous...
Abstract Data provided by the Southeast Area Monitoring and Assessment Program (SEAMAP) shrimp/groundfish trawl survey have long been used in assessing diverse managed taxa, including several reef fishes; however, there are rising concerns over impacts of trawling on live‐bottom habitats. Using data collected from summer SEAMAP surveys (2009–2016; N = 1,103), we examined how avoiding areas habitat might affect survey's ability to assess interannual changes abundance fish taxa. Trawl samples...
Scientists and managers worldwide have increasingly advocated the use of marine protected areas (MPAs) to protect at—risk fish stocks. Most MPAs, however, been established reefs, while nonreef habitats, such as seagrasses, received less consideration. In January 2007, an MPA called Research Natural Area (RNA), was a no—take reserve in Dry Tortugas National Park, Florida (DTNP), becoming first within park boundaries offer direct protection seagrasses reef habitat. We conducted study using...
A 1200 kHz broadband ADCP from RD Instruments was calibrated and used to collect quantitative volume backscattering data zooplankton in the Gulf of Mexico. Voltages on four receivers, reported terms ‘‘counts,’’ were linear with respect received sound pressure level dB re 1 μPa, sensitivities 2.376 2.434 counts/dB, depending receiver. Source levels ranged 212.9 214.6 μPa at m. The mounted C/V Admiral Semmes survey around an oil platform Volume strengths measured between −40 −90 dB, which...
Abstract Recognized limitations of fishery‐dependent data under rapidly changing management regimes have resulted in significant effort during recent years to improve the availability fishery‐independent southeastern United States. These surveys target numerous species and habitats with various sampling methods, including use trawls, longlines, gill nets, traps, visual surveys. Although passively fished hooked gear (e.g., longlines) are often used assess abundance life history managed reef...
