attribute NC_GLOBAL acquisition_description String We quantified larval fingerprints during spawning at each of the potential\nsource populations to develop a reference map that will allow us to assign\nsettled mussels to natal sites based on the elemental fingerprints of their\nlarval shell. To develop a reference map of elemental signatures, we reared\nlarvae in situ at each major mussel population (see sample locations data).\nAfter populations spawned in the field (based on our monitoring of gonad\nindices in each population) adult mussels from multiple sites were collected,\nspawned in the laboratory and the eggs fertilized. Within 24-48 hours (before\nshell formation begins) larvae were placed into small chambers and moored in\nsitu at 3-5m depth. Because spawning varied among the populations, we\nstaggered our deployment of larvae to coincide with our estimates of spawning\ntimes. After four weeks, larval mussels were removed from in situ chambers,\nshells were rinsed in deionized water, dried and prepared for ICPMS. Settlers\nwere collected from settlement plates deployed at each population.\n \nElemental concentrations were determined from single spot ablation in larval\nshells (85% energy, 10 hz, 200 shots, 25 \\u03bcm spot diameter) for both\nlarvae and settlers. Elemental compositions were quantified by external\ncalibration (USGS MACS-3) and internal standardization. We quantified\nelemental compositions from count per second (cps) measurements of 24Mg, 55Mn,\n59Co, 88Sr, 138Ba, 139La, 208Pb and 46Ca using laser ablation inductively\ncoupled mass spectrometry (213 Nd:YAG laser coupled with Elan DRC II ICPMS) at\nthe University of Massachusetts, Boston (LA-ICPMS). Elemental abundances were\ncalculated as analyte cps/ 43Ca cps. We performed a one-point calibration\nusing gas blank and MACS-3, and ran MACS-1 as a check standard every ten\nsamples. Analytical accuracy and precision based on repeated check standard\nanalyses was 96 + 4.4% (mean + sd). Each sample was analyzed in triplicate and\nmean concentrations normalized to calcium are reported.\n \nLocation:  \n Gulf of Maine: Frenchmen Bay (44 28.239 N -68 15.927 W) to Machais Bay (44\n39.350 N -67 21.320 W).

attribute NC_GLOBAL projects_0_acronym String MuLTI-2
attribute NC_GLOBAL projects_0_description String Acronym \"MuLTI-2\" (Mussel Larval Transport Initiative-2)\nExtracted from the NSF award abstract:\nExisting larval transport models focus mainly on along-shelf transport and have done little to explicitly incorporate the effects of cross-shelf mixing and transport processes. Yet cross-shelf transits (both outgoing and incoming legs) are critical components of the dispersal paths of coastal invertebrates. This project will explore the role of cross-shelf mixing in the connectivity of blue mussel populations in eastern Maine. Previous work has shown that the Eastern Maine Coastal Current (EMCC) begins to diverge from shore southwest of the Grand Manan Channel and creates a gradient in cross-shelf mixing and larval transport, with cross-shelf mixing being more common on the northeastern end, episodic in the transitional middle area, and then becoming rare in the southwestern half of the region of the Gulf of Maine. As a result, the investigators predict that northeastern populations of mussels are seeded mostly from up-stream sources, while a significant component of self-seeding (local retention) exists in southwestern populations. Larvae settling in the intervening bays are expected to be derived from a mixture of local and up-stream sources. Using a combined empirical and theoretical approach hydrographic, current profile, and larval vertical migration data will be collected and used to develop and validate a high-resolution coastal circulation model coupled to a model of larval behavior. The investigators will model simulations in different years using the empirical data from mussel reproductive output and spawning times. Connectivity predicted from this model will be then tested against independent empirical estimates of connectivity based on trace element fingerprinting for larvae which can be connected to specific natal habitats. Regions of agreement and discrepancy in the model will be identified to guide additional data collection and model refinement. This iterative process will ensure an understanding of both larval transport patterns and processes, and provide estimates of inter-annual variability in connectivity for blue mussel populations in the Gulf of Maine.

attribute NC_GLOBAL projects_1_description String Rocky intertidal habitats in the Gulf of Maine (GoM) provide a model system to examine the structure and dynamics of natural communities. Throughout the Gulf of Maine, the same species are often found in these habitats but community structure, dynamics and productivity differ markedly among 3 distinct regions (southern, central and northern GoM). Past influential work, conducted primarily in the southern and central GoM, focused on the local processes driving intertidal community structure but produced very different conceptual models of how these communities are structured. This project examines whether regional differences in rocky shore community processes are driven by differences in recruitment that are shaped by regional variation in temperature and food availability and nearshore coastal oceanography. This project will improve the understanding of how large-scale environmental forces interact with local processes to control the distribution of species and the structure and dynamics of these communities. Understanding the interaction between processes operating at different scales is fundamentally important to developing more reliable models that can be used to predict community dynamics. In addition, data resulting from this project will have important implications for regional dynamics in commercially important species and for ecosystem and fisheries management within the GoM.\nThe overarching hypothesis of this project is that regional differences in community-level processes are driven by very different patterns of population connectivity and recruitment in a few key species, and that these differences are ultimately caused by regional variation in temperature and food availability and mediated by physical larval transport processes. Hence, the project will test the following hypotheses with manipulative field experiments, field sampling, connectivity estimates, and integrative modeling:\n1) Locally-dispersing species dominate dynamics in regions with a net export of planktonic larvae (Northern GoM), while species with planktonic larvae dominate the dynamics in regions with high settlement and extensive connectivity among populations (Southern GoM).\n2) Settlement density of species with planktonic larvae increases from northern to southern regions in accord with regional variation in food availability.\n3) Population connectivity varies greatly among regions, with regions differing in the degree to which they are self-seeded or serve as larval sources vs. sinks; self-seeding leads to relatively localized population dynamics in the middle portion of the GoM.\n4) Patterns of population connectivity are driven by physical transport processes and can be represented by coupling basic larval behavior models with circulation models.\nAt 18 different sites in the GoM across ~ 600 km, surveys will evaluate variation in recruitment, food availability and secondary productivity and experiments will assess community processes in wave-exposed and sheltered habitats. We will use hydrographic, current profile, and larval vertical distribution surveys to collect data for coupled larval/circulation models. Population connectivity will be both modeled and empirically evaluated (for one species) using elemental fingerprinting. A spatially explicit metacommunity model will integrate across all project components and test the relative importance of regional and local processes in controlling community organization and dynamics.
