Population connectivity shifts at high frequency within an open-coast marine protected area network.

A complete understanding of population connectivity via larval dispersal is of great value to the effective design and management of marine protected areas (MPA). However empirical estimates of larval dispersal distance, self-recruitment, and within season variability of population connectivity patterns and their influence on metapopulation structure remain rare. We used high-resolution otolith microchemistry data from the temperate reef fish Hypsypops rubicundus to explore biweekly, seasonal, and annual connectivity patterns in an open-coast MPA network. The three MPAs, spanning 46 km along the southern California coastline were connected by larval dispersal, but the magnitude and direction of connections reversed between 2008 and 2009. Self-recruitment, i.e. spawning, dispersal, and settlement to the same location, was observed at two locations, one of which is a MPA. Self-recruitment to this MPA ranged from 50-84%; within the entire 60 km study region, self-recruitment accounted for 45% of all individuals settling to study reefs. On biweekly time scales we observed directional variability in alongshore current data and larval dispersal trajectories; if viewed in isolation these data suggest the system behaves as a source-sink metapopulation. However aggregate biweekly data over two years reveal a reef network in which H. rubicundus behaves more like a well-mixed metapopulation. As one of the few empirical studies of population connectivity within a temperate open coast reef network, this work can inform the MPA design process, implementation of ecosystem based management plans, and facilitate conservation decisions

A Meeting of the Minds: Enhancing Collaboration with the Department of Psychiatry through the Institutional Repository

This presentation will provide an overview of an ongoing collaboration between the Lamar Soutter Library and the Department of Psychiatry at the University of Massachusetts Medical School (UMMS) to promote faculty research. The Library has a long-standing liaison relationship with the Department of Psychiatry to share information about library collections and services, and to support the department’s teaching, clinical, and research needs. In 2009 the Library formally established a Research and Scholarly Communication Services department, with one librarian overseeing the university’s institutional repository, eScholarship@UMMS. eScholarship@UMMS is a digital archive offering worldwide access to the research and scholarly output of the University of Massachusetts Medical School community. Its goal is to bring together all of the University\u27s research under one umbrella, in full text whenever possible, in order to preserve, promote, and provide access to that research. Important features include usage statistics, optimized indexing in Google and Google Scholar, the opportunity to create a personal researcher page, electronic journal publishing software, RSS feeds and email alerts, and ongoing Library support and administration. The Library leveraged the existing liaison relationship with the Department of Psychiatry to advocate for the use of eScholarship@UMMS as a tool to maximize the readership and impact of faculty scholarship. The Department has proven to be an enthusiastic collaborator. eScholarship@UMMS has been enhanced with new research materials, faculty researcher pages, and the publication of an electronic journal. This project serves as a model for library collaboration with faculty departments to support and preserve faculty research output.

Dr. Samuel B. Woodward: A 19th Century Pioneer in American Psychiatric Care

Objective: Showcase the life and work of Dr. Samuel B. Woodward, the medical superintendent of one of the first public hospitals for the mentally ill in the U.S., the Worcester State Hospital in Worcester, Mass. Dr. Woodward overcame then-popular views of mental illness to champion compassionate, optimistic, and individualized treatment for patients. Methods: Dr. Samuel B. Woodward brought a significant paradigm shift to the dark world of mentally ill indigent citizens of Massachusetts in the early 19th century. When Dr. Woodward became the first superintendent of Worcester State Hospital in 1833, mentally ill patients were viewed with suspicion and fear and were usually relegated to prisons and poorhouses. Woodward rejected a supernatural explanation of mental illness that was very popular at that time. He believed mental illness was a somatic disease, not unlike other diseases. His approach, called “moral therapy,” consisted of kind, compassionate, individualized care that respected the patient as a human being. Dr. Woodward was also instrumental in the burgeoning field of psychiatry. He was a prolific writer and became the first president of the organization that would later become the American Psychiatric Association.

Control of deep-sea benthic community structure by oxygen and organic-matter gradients in the eastern Pacific Ocean

At boundaries of oxygen minimum zones (OMZs), bathyal faunas experience steep gradients in oxygen and organic-matter availability. The present study compares changes in microbial, meiofaunal, macrofaunal and megafaunal benthic assemblages along these gradients on Volcano 7, a 2.3-km high seamount in the eastern tropical Pacific. Faunal tolerance to dysaerobic (low oxygen) conditions varies with organism size; microbial and meiofaunal abundances are less affected than macro- and megafaunal abundances. At the exceedingly low concentrations (\u3c0.1 ml/l) encountered on the upper summit of Volcano 7, oxygen appears to exert primary control over abundance, composition and diversity of macrofauna, overriding other factors such as food availability and sediment grain size. When oxygen concentration is sufficient, food availability in sediments (indicated by the presence of labile material such as chlorophyll a) is highly correlated with meiofaunal and macrofaunal abundance. Four distinct physical zones were identified on Volcano 7: (1) the coarse-grained upper summit zone (730–770 m) where near-bottom oxygen concentrations were usually lowest (often \u3c0.1 ml/l) and organic-matter (% organic carbon and chlorophyll a) availability was high, (2) the coarse-grained lower summit (770–1000 m) where near-bottom oxygen concentrations were usually slightly higher (0.11 to 0.16 ml/l) and organic-matter availability remained high, (3) the coarse-grained flank (1000–2000 m) where oxygen concentration was intermediate (0.7–0.9 ml/l) and sediment organic-matter content was very low, and (4) the finer-grained base (2000–3500 m) where oxygen values exceeded 2.5 ml/l, sediment organic carbon was moderate, and chlorophyll a was low. Abundances of larger forms (megafauna and macrofauna) were severely reduced on the upper summit, but attained high values (2.25/m2 and 8,457/m2 respectively) just tens of meters below. The smaller forms (bacteria and meiofauna) attained peak abundances on the low-oxygen upper summit, however, abundances of harpacticoid copepods were greatly reduced on the upper and lower summit, presumably due to oxygen limitation. Macrofaunal abundance and diversity patterns along the Volcano 7 oxygen/enrichment gradient resembled those typically observed along shallow-water gradients of organic pollution. Low densities of a few soft-bodied, low-oxygen tolerant species resided on the upper summit, a high-density, low-diversity assemblage inhabited the lower summit, and low-density, high-diversity assemblages occupied the flank and base sediments. The infaunal communities on Volcano 7 support the idea that OMZ boundaries are regions of enhanced biological activity. Modern faunal distributions and biogenic structures at OMZ boundaries may be useful in reconstructing oxygenation histories of ancient marine basins

Making Women\u27s Health Connections: Between Researchers and to Resources

The Lamar Soutter Library at the University of Massachusetts Medical School has recently completed the second year of a National Library of Medicine grant funded project; the Women’s Health Resources Dissemination Outreach Project. The goals include assisting women’s health researchers by providing them with access to information and making them more aware of opportunities and available resources. This, ultimately, enables both an improvement in women’s health and the advancement of women in academic medicine. Moreover, by supporting women’s health research and women researchers through the objectives of this project, women researchers build connections, knowledge, and skills. This facilitates meaningful contributions and fosters greater promotion and leadership opportunities for these women. This poster describes the goals, activities, and progress of the project through the completion of the second year. Specific programs and initiatives are highlighted. This includes the multi-year endeavor to build, recruit, and showcase women’s health researchers in a specific collection of eScholarship@UMMS, the library’s institutional repository. Promotion and outreach, of both the project and the resources, was major component of the second year. Additionally, programming was developed that helped researchers better communicate their work to the media and public. Other programs, lessons learned, successes, and future goals are noted

Contrasting effects of substrate mobility on infaunal assemblages inhabiting two high-energy settings on Fieberling Guyot

The influence of seamount-intensified flows on the structure of infaunal assemblages was examined at two sand-covered sites located 2.3 km apart atop the summit plain of Fieberling Guyot (32°27.6′N 127° 48.0′W). Both sites experience strong, tidal bottom currents with flows exceeding 20 cm/s on a daily basis (4 mab). Estimates of shear velocity (u*) did not differ significantly between the two sites. However, differences in sediment composition and density produced different sediment transport regimes at the two sites. At Sea Pen Rim (SPR), located on the NW perimeter (635 m), sedimentary particles were composed primarily of basaltic sands that experienced negligible transport during the study period. At White Sand Swale (WSS, 580 m), a narrow valley enclosed on three sides by basalt outcrops, sediments were composed almost entirely of foraminiferal sands that moved daily. Sediment organic content and microbial abundances were similar at the two sites. Infauna (\u3e300 μm) had higher densities at WSS (1870/m2) than SPR (1489/m2), but lower expected species richness. Although the 2 sites shared nearly 50% of identified species, peracarid crustaceans, echinoderms, sponges, and bryozoans were proportionally more important in the stable substrates of SPR, while turbellarians, bivalves, and aplacophorans were better represented in the shifting sands of WSS. The infauna of WSS lived deeper in the sediment column (\u3e50% below 2 cm) than that of SPR (\u3e 50% in the upper 1 cm), at least partly because the majority (83%) at WSS were subsurface burrowers with motile lifestyles. Tube-building and epifaunal lifestyles were more common at SPR than WSS, as were surface-deposit and filter-feeding modes. Fences and weirs were deployed at the study sites for 6.5-wk and 6-mo periods to manipulate bottom stress. Changes in faunal patterns within weirs at WSS reinforced our conjecture that contrasting sediment transport regimes explain between-site differences in community structure. Fence effects varied with deployment period and site. Topographic features on Fieberling Guyot produce heterogeneous sedimentary settings characterized by different transport regimes. Our results suggest that substrate mobility exerts primary control over infaunal community structure at the two high-energy sites

Carbonate-hosted methanotrophy represents an unrecognized methane sink in the deep sea

The atmospheric flux of methane from the oceans is largely mitigated through microbially mediated sulphate-coupled methane oxidation, resulting in the precipitation of authigenic carbonates. Deep-sea carbonates are common around active and palaeo-methane seepage, and have primarily been viewed as passive recorders of methane oxidation; their role as active and unique microbial habitats capable of continued methane consumption has not been examined. Here we show that seep-associated carbonates harbour active microbial communities, serving as dynamic methane sinks. Microbial aggregate abundance within the carbonate interior exceeds that of seep sediments, and molecular diversity surveys reveal methanotrophic communities within protolithic nodules and well-lithified carbonate pavements. Aggregations of microbial cells within the carbonate matrix actively oxidize methane as indicated by stable isotope FISH–nanoSIMS experiments and ^(14)CH_4 radiotracer rate measurements. Carbonate-hosted methanotrophy extends the known ecological niche of these important methane consumers and represents a previously unrecognized methane sink that warrants consideration in global methane budgets
