Connectivity results from a combination of biological traits and physical mechanisms, at different life stages. We focus on the transport of particles around an oceanic island, simulating transport at early life stages of marine organisms. We aim to investigate through case studies how mesoscale features influence particle transport, recruitment, and connectivity. We determine particle dispersion by using an individual‐based model and the flow fields derived from a regional implementation of an ocean circulation model. To understand the underlying physical processes of transport, we locate coherent structures in the flow field, identify recurrent physical features, and observe how particle transport is related to them. Our results show that the varying eddying flow increases connectivity among populations located on different sides of the island. Both the flow field and dispersal patterns are highly...

Dose-response relationships with expected oil concentrations were utilized to estimate the impact on fish growth and mortality rates. We also examine the effects of fisheries closures and impacts on recruitment. We validate predictions of the model by comparing population trends and age structure before and after the oil spill with fisheries independent data. The model suggests that recruitment effects and fishery closures had little influence on biomass dynamics. However, at the assumed level of oil concentrations and toxicity, impacts on fish mortality and growth rates were large and commensurate with observations. Sensitivity analysis suggests the biomass of large reef fish decreased by 25% to 50% in areas most affected by the spill, and biomass of large demersal fish decreased even more, by 40% to 70%. I...

It is also indispensable for the development and adjustment of oil fate modeling tools that estimate the subsea distribution of oil masses. So far, to estimate the oil distribution throughout the water column and the expected surfacing times, a couple of well-known correlations for the calculation of the rise velocities of single particles with fluidic interfaces in stagnant media are available from process engineering applications. Besides the physical properties of live oil under environmental conditions, the size of the gas bubbles and oil droplets are the most crucial parameters that determine rise velocities.

Recent studies have shown that reef soundscapes are comprised of abiotic sounds (such as the breaking of waves), biological sounds (such as animals moving, mating, or foraging) and anthropogenic sounds (such as boat noise). Each reef has a unique “sound signature” which may be an indicator of habitat quality. Several studies have demonstrated that settlement-stage larvae of various reef fishes may be attracted to reef sounds, yet few investigators have measured the temporal and spatial patterns of these sounds. Furthermore, to our knowledge, the linkage between acoustic signatures and natural settlement behavior of reef fish has not been examined. We selected two sites (Pickles and Sand Island Reefs, 8 km apart along the reef tract in the upper Florida Keys, USA) based on a time series of settlement data. Light-traps were used to collect settlement-stage reef fish during peak settlement times (new to third-quarter moon each month) during each of tw...

They also establish the physical environment within which biogeochemical and other processes transform materials, including naturally occurring nutrients and human-made contaminants that may sustain or harm the region’s living resources. Thus, understanding and modeling the transport and distribution of materials provides a crucial substrate for determining the effects of biological, geological, and chemical processes. The wide range of scales in which these physical processes operate includes microscale droplets and bubbles; small-scale turbulence in buoyant plumes and the near-surface “mixed” layer; submesoscale fronts, convergent and divergent flows, and small eddies; larger mesoscale quasi-geostrophic eddies; and the overall large-scale circulation of the Gulf of Mexico and its interaction with the Atlantic Ocean and the Caribbean Sea; a...

A polyclonal antiserum produced to the single chained glycoprotein wastested with 14 other lutjanid extracts in Western blots and produced 3 different patterns: strong reactions with L. jocu and L. apodus; weak reactions with L. buc canella, L. synagris, L. anaUs, L. campechanus, Pristipomoides aqui lonaris, OcyUTUS chrysurus, andApsilus dentatus; no reactions with L. vivanus, L. mahogoni, L. cyanopterus, Etelis oculata, and the hybrid L. synagris x O. chrysurus. The anti-66 kDa antiserum alRO Tp.llct.Ad RtTong!y with soluble ex tracts of oocytes and juveniles of L. griseus. Adsorption of the IgG fraction ofthe antiserum with glutaraldehyde insolubilized L. apodus extract resulted in an antiserum that remained strongly reactive with L. griseus extract but that was weakly reactive with L. apodus extract and negative with L. jocu ex tract in Western blots. The N-terminal amino acid sequence analyses of the first 10 residues ofthe purified 66 kDa proteins ofL. griseus and L. jocu were approximately the same, but only 3 of 10 residues were the same with the purified proteins of L. griseus and L. apodus. Extracts of L. apodus con tained 3 additional proteins that were not detected in extracts of L. griseus as determined by SDS-PAGE. This evi dence for both interspecies and species specific protein determinants is cur rently being used to produce species specific polyclonal and monoclonal an tisera for identifying species oflutjanid fishes at early life history stages.

After the Deepwater Horizon (DWH) disaster, these ecological processes facilitated dispersal of oil-spill toxicants or were damaged and broken. A considerable portion of post-DWH research focused on higher levels of biological organization (i.e., populations, communities, and ecosystems) spanning at least four environments (onshore, coastal, open ocean, and deep benthos). Damage wrought by the oil spill and mitigation efforts varied considerably across ecosystems. Whereas all systems show prolonged impacts because of cascading effects that impacted functional connections within and between communities, deep-sea and mesopelagic environments were particularly hard hit and have shown less resilience than shallow environments. In some environments, such as marshes or the deep-sea benthos, products from the spill are still biologically accessible. Some shallow ecosystems show signs of recove...
