Padanaram Harbor Management Plan

The Padanaram Harbor Management Plan was developed over a two‐year period, from 2017–2019, by a broad spectrum of Dartmouth governmental officials, citizens of the Town, regional and state agency staff, and representatives of non‐governmental organizations. There was significant public involvement through open meetings and an online survey. During the entire process, drafts of elements of the Plan were posted on the website of the Planning Board as they became available. The work was supported in consultation with staff of the Urban Harbors Institute from the University of Massachusetts Boston. Funding was provided through a grant from the Massachusetts Seaport Economic Council and a local match

Vision-Based Cranberry Crop Ripening Assessment

Agricultural domains are being transformed by recent advances in AI and computer vision that support quantitative visual evaluation. Using drone imaging, we develop a framework for characterizing the ripening process of cranberry crops. Our method consists of drone-based time-series collection over a cranberry growing season, photometric calibration for albedo recovery from pixels, and berry segmentation with semi-supervised deep learning networks using point-click annotations. By extracting time-series berry albedo measurements, we evaluate four different varieties of cranberries and provide a quantification of their ripening rates. Such quantification has practical implications for 1) assessing real-time overheating risks for cranberry bogs; 2) large scale comparisons of progeny in crop breeding; 3) detecting disease by looking for ripening pattern outliers. This work is the first of its kind in quantitative evaluation of ripening using computer vision methods and has impact beyond cranberry crops including wine grapes, olives, blueberries, and maize

Reactions of Narwhals, Monodon monoceros, to Killer Whale, Orcinus orca, Attacks in the Eastern Canadian Arctic

A Killer Whale attack on Narwhals was observed at Kakiak Point in Admiralty Inlet, Nunavut, Canada, in August 2005. Behavioral responses of both Narwhals and Killer Whales were documented by direct observation. Data collected from Narwhals instrumented with satellite-linked transmitters 5 days prior to the arrival of Killer Whales were used to examine changes in Narwhal movement patterns (e.g., dispersal and clumping) five days before the attack, during the attack, and five days after Killer Whales left the area. A minimum of four Narwhals were killed by 12-15 Killer Whales in a period of 6 hours. Narwhals showed a suite of behavioral changes in the immediate presence of Killer Whales including slow, quiet movements, travel close to the beach (<2 m from shore), use of very shallow water, and formation of tight groups at the surface. These behavioral changes are consistent with Inuit accounts of Killer Whale attacks on Narwhals. During the attack, Narwhals dispersed broadly, the groups were less clumped (standard deviation of inter-whale mean latitudes and longitudes), Narwhal space-use doubled from pre-attack home ranges of 347 km2 to 767 km2 (kernel 50% probability), and Narwhals shifted their distribution further south of the attack site. After the disappearance of Killer Whales, north-south dispersal of Narwhals contracted and was similar to pre-attack levels, total space use decreased slightly (599 km2), yet west-east dispersal remained high. Narwhals were distributed significantly (P < 0.001) more broadly offshore in areas not used before the occurrence of Killer Whales. In general, short-term reactions of Narwhals to Killer Whale presence were obvious; yet normal behavior (as observed from shore) resumed shortly after Killer Whales left the area. Long-term (five day) Narwhal behavioral responses included increased dispersal of Narwhal groups over large offshore areas. This is among the few reports of eyewitness Killer Whale attacks on Narwhals in the high Arctic and is the first time changes in Narwhal behavior have been documented in response to a predation event through the use of satellite telemetry

Housing Preferences and Choices Among Adults with Mental Illness and Substance Use Disorders: A Qualitative Study

Housing is a crucial issue for adults with severe mental illness and co-occurring substance use disorders, as this population is particularly susceptible to housing instability and homelessness. We interviewed 40 adults with dual disorders, living in either supervised or independent housing arrangements, to examine housing preferences, decision making processes surrounding housing choices, and perceived barriers to housing. We found that many clients indicated their housing preferences had changed over time, and some clients related housing preferences to recovery. Although the majority of clients preferred independent housing, many also described benefits of supervised housing. Clients' current living situations appeared to be driven primarily by treatment provider recommendations and availability of housing. Common barriers to obtaining desired housing were lack of income and information. These findings have implications for supported housing models and approaches to providing housing for clients

Defining the budding yeast chromatin-associated interactome

We report here the first large-scale affinity purification and mass spectrometry (AP-MS) study of chromatin-associated protein, in which over 100 different baits involved in chromatin biology were studied by modified chromatin immunopurification (mChIP)-MS. In particular, focus was placed on poorly studied chromatin binding proteins, such as transcription factors, which have been underrepresented in previous AP-MS studies.mChIP-MS analysis of transcription factors identified dense networks of protein associated with chromatin that were composed of specific transcriptional co-activators, information not accessible through the use of classical AP-MS methods.Finally, we demonstrate that novel protein–protein interactions identified in study by mChIP have functional implications exemplified by the detailed study of both the ubiquitination of the proline isomerase Cpr1 and of histone chaperones involved in the regulation of the HTA1-HTB1 promoter.Our work demonstrates the value of targeted interactome studies, in which affinity purification methods are adapted to the needs of specific baits, as is the case for chromatin binding proteins

Nantucket Shellfish Management Plan

Nantucket’s shellfish resources are an important part of the Island’s history, culture, and economy. Nantucket waters support one of the country’s last wild-caught bay scallop fisheries. Elsewhere along the Atlantic coast, fishing pressure, habitat loss, and disease have severely depleted bay scallop populations. Although Nantucketers continue to make a living harvesting shellfish from the Island’s waters, many do so with concern for the future of the resources and the habitats that support them. Urban Harbors Institute (UHI) provided technical assistance to the community to develop a Shellfish Management Plan (SMP) that addresses issues of water quality, habitat loss, climate change, shellfish propagation, regulatory concerns, and the sustainability of the commercial and recreational fishery. Of particular value is the outline of future research needed to support management activities. Species addressed include: Bay scallop, Conch, Mussel, Quahog, Oyster, and Soft-Shell Clam

2010 Massachusetts Recreational Boater Survey: Final Report Submitted to the Massachusetts Ocean Partnership

The Massachusetts Ocean Management Plan (Plan) completed in 2009 recognized recreational boating as an activity with “significant actual and prospective conflicts among multiple waterway uses in Massachusetts” and included the economic value of recreational boating as a key socio-economic indicator that will be used to inform coastal management. At the time of Plan completion, statistically robust recreational boating data were identified as an important need for comprehensive ocean planning. To fill this data gap, the 2010 Massachusetts Recreational Boater Survey gathered information on boating activity in Massachusetts’ coastal and ocean waters directly from recreational boaters. Researchers sent 10,000 surveys to owners of Massachusetts registered and documented vessels in the spring of 2010 asking for participation in the six month study. Over 22% responded and provided detailed information through monthly surveys between May and October about their boating trips including expenditures, recreational activities, and routes. Boaters plotted their spatial data (routes and activity areas) using an innovative online open source mapping tool. Using statistical methods and economic models, the demographic and economic information from the sample of boaters was generalized to the population of Massachusetts boaters. Results revealed the economic contribution of this activity to the Massachusetts economy - an estimated $806 million in 2010. Information gathered through the survey was also compiled into comprehensive maps depicting recreational boating patterns and density, and was used to better understand details of the recreational boating community, such as the most common boat size, the typical age of Bay State boaters, etc. The research findings will be incorporated into the Massachusetts Ocean Management Plan and can be used by resource managers, the boating industry and others in many ways, such as ensuring boating routes and destinations receive appropriate attention in ocean planning efforts

Developing Performance Indicators to Evaluate the Management Effectiveness of the Massachusetts Ocean Management Plan

In June 2009, the Massachusetts Executive Office of Energy and Environmental Affairs (EEA) released its draft Massachusetts Ocean Management Plan (draft plan) for public comment. The plan is required by the Oceans Act of 2008 to, among other things, be adaptive to evolving knowledge and understanding of the ocean environment. The plan’s Science Framework establishes a blueprint for future research and data acquisition and ensuring that the plan evolves and its management measures adapt to this new and enhanced information. As stated in Chapter 5 of the draft plan, an important part of the science framework is the development and implementation of a performance evaluation system with a series of indicators to help EEA and stakeholders evaluate the implementation of the Massachusetts Ocean Management Plan, identify the environmental and socio-economic impacts of plan management decisions, and identify new or emerging issues. Volume 2 of the draft plan contains a section entitled Development of Evaluation Measures for the Massachusetts Ocean Management Plan. This section outlines a proposed process “to identify measures of success or indicators that can be used to measure performance of management strategies in achieving desired outcomes.” As the development of indicators is a high priority of the draft plan, the Massachusetts Ocean Partnership (MOP) in consultation with EEA contracted with the Urban Harbors Institute (UHI) of the University of Massachusetts Boston (UMass Boston). The project team1 and other professionals from organizations and agencies experienced with the selection and use of indicators conducted the process outlined in Volume 2 of the draft plan to identify and select a set of environmental, socio-economic, and governmental indicators to evaluate the effectiveness of the Massachusetts Ocean Management Plan. The work described in this report also contributes to a broader interest and goal of the Massachusetts Ocean Partnership which is to coordinate indicator initiatives to inform ocean management and to advance the development and use of indicators of the ocean’s ability to provide ecosystem services. Currently, there are a number of initiatives, focusing on the coastal and ocean areas of the Northwest Atlantic/Gulf of Maine region, to develop indicators for various purposes and audiences. The process and products of this work in support of the Massachusetts Ocean Management Plan (e.g., the list of indicators and associated data) will be useful in collaborative efforts to integrate and coordinate these regional efforts
