The role of sand lances (Ammodytes sp.) in the Northwest Atlantic ecosystem: a synthesis of current knowledge with implications for conservation and management. Fish and Fisheries, 00, (2020): 1-34, doi:10.1111/faf.12445.The American sand lance (Ammodytes americanus, Ammodytidae) and the Northern sand lance (A. dubius, Ammodytidae) are small forage fishes that play an important functional role in the Northwest Atlantic Ocean (NWA). The NWA is a highly dynamic ecosystem currently facing increased risks from climate change, fishing and energy development. We need a better understanding of the biology, population dynamics and ecosystem role of Ammodytes to inform relevant management, climate adaptation and conservation efforts. To meet this need, we synthesized available data on the (a) life history, behaviour and distribution; (b) trophic ecology; (c) threats and vulnerabilities; and (d) ecosystem services role of Ammodytes in the NWA. Overall, 72 regional predators including 45 species of fishes, two squids, 16 seabirds and nine marine mammals were found to consume Ammodytes. Priority research needs identified during this effort include basic information on the patterns and drivers in abundance and distribution of Ammodytes, improved assessments of reproductive biology schedules and investigations of regional sensitivity and resilience to climate change, fishing and habitat disturbance. Food web studies are also needed to evaluate trophic linkages and to assess the consequences of inconsistent zooplankton prey and predator fields on energy flow within the NWA ecosystem. Synthesis results represent the first comprehensive assessment of Ammodytes in the NWA and are intended to inform new research and support regional ecosystemâbased management approaches.This manuscript is the result of followâup work stemming from a working group formed at a twoâday multidisciplinary and international workshop held at the Parker River National Wildlife Refuge, Massachusetts in May 2017, which convened 55 experts scientists, natural resource managers and conservation practitioners from 15 state, federal, academic and nonâgovernmental organizations with interest and expertise in Ammodytes ecology.

Satellite sensor requirements for monitoring essential biodiversity variables of coastal ecosystems
© The Author(s), 2018. This article is distributed under the terms of the Creative Commons Attribution License. The definitive version was published in Ecological Applications 28 (2018): 749-760, doi: 10.1002/eap.1682.The biodiversity and high productivity of coastal terrestrial and aquatic habitats are the foundation for important benefits to human societies around the world. These globally distributed habitats need frequent and broad systematic assessments, but field surveys only cover a small fraction of these areas. Satelliteâbased sensors can repeatedly record the visible and nearâinfrared reflectance spectra that contain the absorption, scattering, and fluorescence signatures of functional phytoplankton groups, colored dissolved matter, and particulate matter near the surface ocean, and of biologically structured habitats (floating and emergent vegetation, benthic habitats like coral, seagrass, and algae). These measures can be incorporated into Essential Biodiversity Variables (EBVs), including the distribution, abundance, and traits of groups of species populations, and used to evaluate habitat fragmentation. However, current and planned satellites are not designed to observe the EBVs that change rapidly with extreme tides, salinity, temperatures, storms, pollution, or physical habitat destruction over scales relevant to human activity. Making these observations requires a new generation of satellite sensors able to sample with these combined characteristics: (1) spatial resolution on the order of 30 to 100âm pixels or smaller; (2) spectral resolution on the order of 5 nm in the visible and 10 nm in the shortâwave infrared spectrum (or at least two or more bands at 1,030, 1,240, 1,630, 2,125, and/or 2,260 nm) for atmospheric correction and aquatic and vegetation assessments; (3) radiometric quality with signal to noise ratios (SNR) above 800 (relative to signal levels typical of the open ocean), 14âbit digitization, absolute radiometric calibration <2%, relative calibration of 0.2%, polarization sensitivity <1%, high radiometric stability and linearity, and operations designed to minimize sunglint; and (4) temporal resolution of hours to days. We refer to these combined specifications as H4 imaging. Enabling H4 imaging is vital for the conservation and management of global biodiversity and ecosystem services, including food provisioning and water security. An agile satellite in a 3âd repeat lowâEarth orbit could sample 30âkm swath images of several hundred coastal habitats daily. Nine H4 satellites would provide weekly coverage of global coastal zones. Such satellite constellations are now feasible and are used in various applications.National Center for Ecological Analysis and Synthesis (NCEAS);

Maine Sea Grant Annual Report 2013
Sea Grant research supported renewable ocean energy research and development. Maine Sea Grant researchers have developed and defined new approaches to monitoring and assessing environmental impacts associated with tidal power turbines, helping to inform similar efforts nationally and globally. Dr. Gayle Zydlewski and her research team, including Sea Grant scholar Jeffrey Vieser, assessed fish communities associated with Ocean Renewable Power Companyâs tidal energy project in Cobscook Bay. The researchers identified ways that industries and other stakeholders investing in tidal power could save money (using a single beam rather than a split beam echosounder system to monitor fish could save up to $30,000 in equipment costs) and time (by automating acoustic data analyses). Data collected and analyzed by Sea Grant researchers advanced ORPCâs license application process by providing regulatory agencies the best available science, helping to inform the policy changes that were needed to enable tidal power development in the U.S. and abroad. By contributing to the projectâs success, Sea Grant has helped ORPC retain 38 businesses and more than 100 jobs.
Maine Sea Grant is also engaging communities affected by the University of Maineâs offshore wind energy research. The University of Maine is building and testing new floating wind turbine designs for deployment off Midcoast Maine. Fishermen, communities, and other ocean users in the vicinity need opportunities to provide input on the design and deployment, and learn about the goals of the project. Since April 2013, Maine Sea Grant has coordinated community engagement in the project region, including hosting multiple public forums and meetings with lobster, shrimp, and scallop fishermen. Approximately 300 people attended these events in 2013. Maine Sea Grantâs work in communities affected by offshore wind energy research and development have helped to correct misinformation and expand the sphere of engagement, reducing potential conflicts while incorporating more concerns into the development process
