Thomas Bay Salt Marsh Restoration
No full textFor several years, CBEP has worked in close collaboration with Brunswick through the New Meadows Watershed Partnership. The Adams Road project grew out of an exploratory site visit between CBEP staff and the Brunswick Natural Resource Planner during which the round pipe culvert was observed to be undersized and deteriorating. Subsequent discussions with Public Works revealed an opportunity to match Town infrastructure needs with habitat restoration goals, and plans were made to solicit external federal grant funding. CBEP subsequently wrote a successful habitat restoration grant proposal to the Gulf of Maine Council/NOAA Habitat The Adams Road culvert at Thomas Bay Marsh was replaced in August 2011. CBEP Implementation Review June 12, 2012 Restoration Partnership to replace the culvert with a larger volume pipe arch culvert. After close to a year spent on designs and permitting, the culvert was replaced on August 17, 2011

Fishes of Moreton Bay: Ecology, human impacts, and conservation
No full textMoreton Bay is a heterogeneous seascape containing a mosaic of habitats that support a diversity of fish. The fish fauna includes many species that are harvested by recreational and commercial fishers as well as numerous taxa that are of conservation concern. The fish fauna of mangroves, seagrasses, inshore reefs and intertidal flats is well sampled. By contrast, fish surveys in saltmarshes, soft sediments, offshore reefs and surf zones are sparse and incomplete. Fish diversity and abundance are typically highest on reefs and seagrass meadows, but most species move among habitats to feed and spawn. These movements connect habitats and link both fish assemblages and food webs across seascapes. The combined effects of water quality, coastal urbanisation and fishing also shape fish assemblages in Moreton Bay. Fish diversity and abundance increases from the urbanised western to the less developed eastern Bay. This spatial pattern mirrors gradients in water quality and habitat condition across the Bay. The shorelines of many estuaries and ocean beaches have been developed, and this coastal urbanisation has altered fish diversity, abundance and diet. Numerous species have, however, adapted to capitalise on the abundance of food and shelter in urban estuaries. No-take marine reserves prohibit fishing, and this promotes fish abundance and diversity in some ecosystems (e.g. coral reefs, seagrass meadows), but not in others (e.g. estuaries, ocean beaches). Important challenges for future research in Moreton Bay include: (i) testing how multiple human pressures combine to modify fish assemblages and fish habitats; (ii) identifying how the ecological attributes of ecosystems and seascapes shape conservation outcomes; and (iii) examining how fish assemblages, habitats and fisheries change in response to range shifts of tropical species that move south with rising sea temperatures.Full Tex

Hydrothermal areas, microbial mats and sea grass in Paleochori Bay, Milos, Greece
No full textWe collected orthophotos of Paleochori Bay, Milos, Greece in 2018 by drone (Orthophotos.zip) and stitched those images together to obtain a high-resolution, georeferenced photographic image (Paleochori_Composite_Photo.tif). This image was used for further processing in ArcGIS to generate a 1:3300 scale map of the seafloor in Paleochori Bay (tjom_a_1748131_sm0990.pdf) with native shapefiles and layer files (Shapefiles.zip), showing the distribution of white microbial mats, former microbial mats, sea grass and “normal” sand down to a depth of 15 m. The georeferenced photographic image allows to obtain GPS coordinates for any point of interest in Paleochori Bay and thus, allows to target specific locations for data collection, rather than resorting to vague site descriptions, as has been the practice in the past. With aid from the georeferenced photo of Paleochori Bay, 150 sea floor temperatures were measurements by Scuba divers (Temperature_measurments.xlsx) to evaluate the temperature distribution in the bay, in order to further the overall understanding of the hydrothermal system
Performance of marine reserves for fish and associated ecological functions in the Moreton Bay Marine Park
No full textNo-take marine reserves in Moreton Bay were established to conserve and restore the structure and function of marine ecosystems and ensure sustainable social-ecological systems (Ross et al. 2019, this volume). Here, we review published literature to determine our current understanding of how no-take marine reserves (i.e. green zones) benefit fish, and shape ecological functions in numerous ecosystems within the Moreton Bay Marine Park. Over the past decade, 16 peer-reviewed studies have examined ‘reserve effects’ for fish and associated ecological processes in Moreton Bay; this work was mostly conducted in the central part of the Bay in coral reefs and seagrass meadows. Most studies showed enhanced fish abundance, diversity, or both, inside reserves and increases in the levels of functions performed by fish (e.g. greater grazing rates). The degree to which reserves enhance the abundance of fish and their functions was contingent on two key conditions. Reserves that were better connected (i.e. those in proximity to complementary habitat types and situated in a more complex seascape) and those located in clearer water typically perform better and may also be more resilient. Therefore, these two factors must be strongly considered during future deliberations about expanding or modifying reserves in Moreton Bay. We identify a number of information gaps that are likely to impede improvement to the current network of no-take reserves, namely, research on sandy and muddy bottoms, ocean beaches, fishing outside of reserves, and pivotal ecological functions other than herbivory. Reserve design and future rezoning can take advantage of the considerable body of evidence gathered on factors governing reserve performance for fishes, but reserve effects need to be examined for the numerous habitats that have been overlooked. How reserves shape a broader range of functions, productivity, habitat and ecological resilience needs to be investigated.Full Tex

Failed Censures: Ecclesiastical Regulation of Women’s Clothing in Late Medieval Italy
No full textChurchmen in the late thirteenth and early fourteenth centuries tried to regulate the costume of Italian women. These efforts failed, and regulation was largely left thereafter to civic authorities.The published version was published as Chapter 3 in Medieval Clothing and Textiles 5Izbicki, Thomas M.
