Lobster in a Changing Gulf of Maine: Investigating the Temporal Impact on Molting and the Fishing Fleet

We investigated the phenological and fisheries dynamics surrounding the spring molt of American lobster (Homarus americanus, Milne Edwards 1847) in the Gulf of Maine. We created a time series from Maine Department of Marine Resources Lobster Sea Sampling data using logistic models to estimate the timing and duration of the spring molt for eastern, central, and western regions of the Maine coast. These estimates revealed substantial inter-annual variability in the timing of the spring molt for all regions and that 2012 was indeed anomalously early relative to other years. Each region experienced significantly different molt timing for any given year, indicating that there are spatially-distinct molting phenologies along the Maine coastline. Generalized Linear Models were constructed using the molting time series and hindcasted bottom temperatures from the Northeast Coastal Ocean Forecasting System using the Finite Volume Composite Ocean Model to analyze how nearshore and offshore bottom ocean temperatures might shape molting trends and differences. This analysis revealed that the influence of nearshore temperatures was significant in the eastern region only and the relationship between nearshore temperatures and the timing of the spring molt weakened from east to west. Logistic models were also applied to Maine Department of Marine Resources Landings Program data to estimate and evaluate multiple landings-based proxies for the timing of the spring molt via the fishing fleet’s ability to synchronize with the lobster molting phenology. Newshell landings, as a percent of the annual weekly maximum, were identified as the best proxy, given relative difference from the annual in-situ estimates of spring molt timing and lower standard error values. The fleet’s ability to synchronize with variable spring molting phenology was assessed using a correlation analysis. This analysis revealed that both eastern and western fleets followed the same temporal patterns as the lobster molt timing in their region and the western fleet showed a poorer, more variable ability to absolutely synchronize their timing when compared to the eastern fleet. Maine lobstermen were interviewed to investigate how they achieve an optimal synchrony, revealing the utilization of several environmental and non-environmental variables. General temperature, lunar and tidal phases, and Penobscot River discharge were fishermen-nominated variables tested using correlation analysis. These analyses showed that fishermen methodology and its association with spring molt timing were spatially variable. General temperatures displayed the same weakening association with spring molt from east to west; tidal phase was significant in the east only; and river discharge was significantly associated in the eastern and central regions. River discharge association with molting was also temporally variable, showing strongest significant positive relationships during April. We discuss these investigations into the temporal and spatial dynamics of the spring lobster molt along the Maine coast and the fishery’s response to inter-annual variation, creating a baseline of information about the spring molt for Maine. We also discuss the degree to which the fleet is able to approximate and adapt to inter-annual variation in this phenology and some of the methods they have been using to accomplish this synchrony

Public value in public sector infrastructure procurement

There is a growing comprehension of the importance of procurement in realising value for clients of all types. The public sector invests in physical assets to deliver the goods, services and symbols that society values (Winch 2002). The procurement of a construction project in the form of hospitals, schools and courthouses enables government to deliver services in the areas of health, education and justice. This thesis examines how Australian State Government agencies (roads & construction) procure infrastructure projects and the extent to which they view the procurement process as an opportunity to deliver more than just a physical facility. Moore’s (1995) ‘Theory of Public Value’ articulates a more proactive and strategic role for public sector managers who seek to discover, define and produce public value, instead of just devising means for achieving mandated purposes. An approach to infrastructure procurement based solely on lowest cost tendering that focuses on the core business of building a physical facility but not necessarily creating additional value as a by-product fails this test. This thesis presents results drawn from ten case studies of State Government organisations that procure infrastructure. Thirty-seven highly experienced project managers operationally responsible for the procurement of infrastructure within these organisations interviews were interviewed. A semi-structured interview featuring a mixture of open-ended and closed-ended questions was designed to explore a range of issues including; how procurement is undertaken, value-for-money (VFM), selection criteria, government priorities, public value, and supply chain management. The transcribed interviews were coded thematically using provisional codes developed from the research questions (Miles & Huberman 1994, p.58). The qualitative software package NVIVO was then used to help enable inductive coding to further develop the provisional coding structures including the identification of sub-themes and the nature of linkages between themes and sub-themes. The findings showed that the procurement approaches favoured were risk averse and predominantly traditional featuring separate contracts with designers and contractors. Value-for-Money was viewed as a crucial objective of procurement activities by project managers. However, the perceptions of value-for-money were relatively restricted, and largely defined in financial terms and focused on the creation of value within client department domains. Non-price criteria are used, particularly for the selection of designers, but less so for contractors, with lowest priced conforming bids from pre-qualified tenderers frequently awarded contracts. Precisely how non-price criteria is an area worthy of considerable futher investigation. There are some instances where standardised non-price criteria are included in contracts to build in some additional benefits into the way projects are procured. However, the focus of procurement is delivering what Graycar (2007) describes as core-business, optimising procurement for client departments as opposed to outcomes for government as a whole. The evidence suggests that project managers are not relentlessly pursuing value creation opportunities via the procurement process and hence not acting as entrepreneurially or innovatively as Moore (1995) advocates. The data shows that the focus of procurement is often on reducing transaction costs, but not on maximising the strategic contribution or value yielding potential of procurement

Functional relations between locomotor performance traits in spiders and implications for evolutionary hypotheses

<p>Abstract</p> <p>Background</p> <p>Locomotor performance in ecologically relevant activities is often linked to individual fitness. Recent controversy over evolution of extreme sexual size dimorphism (SSD) in spiders centres on the relationship between size and locomotor capacity in males. Advantages for large males running over horizontal surfaces and small males climbing vertically have been proposed. Models have implicitly treated running and climbing as functionally distinct activities and failed to consider the possibility that they reflect common underlying capacities.</p> <p>Findings</p> <p>We examine the relationship between maximum climbing and running performance in males of three spider species. Maximum running and climbing speeds were positively related in two orb-web spiders with high SSD (<it>Argiope keyserlingi </it>and <it>Nephila plumipes</it>), indicating that for these species assays of running and climbing largely reveal the same underlying capacities. Running and climbing speeds were not related in a jumping spider with low SSD (<it>Jacksonoides queenslandica</it>). We found no evidence of a performance trade-off between these activities.</p> <p>Conclusions</p> <p>In the web-spiders <it>A. keyserlingi </it>and <it>N. plumipes </it>good runners were also good climbers. This indicates that climbing and running largely represent a single locomotor performance characteristic in these spiders, but this was not the case for the jumping spider <it>J. queenslandica</it>. There was no evidence of a trade-off between maximum running and climbing speeds in these spiders. We highlight the need to establish the relationship between apparently disparate locomotor activities when testing alternative hypotheses that yield predictions about different locomotor activities. Analysis of slopes suggests greater potential for an evolutionary response on performance in the horizontal compared to vertical context in these spiders.</p

The original publication is available at http://www.samj.org.zaA 10th case of extramedullary plasmacytoma (EMP) of the colon is reported. The term 'primary isolated extramedullary plasmacytoma' is preferred to those terms previously used. A broad classification of plasmacytoma of the gastrointestinal tract is suggested and a management policy, based on this classification, is outlined.Publishers' versio

Phase Stable RF-over-fiber Transmission using Heterodyne Interferometry

New scientific applications require phase-stabilized RF distribution to multiple remote locations. These include phased-array radio telescopes and short pulse free electron lasers. RF modulated onto a CW optical carrier and transmitted via fiber is capable of low noise, but commercially available systems aren't long term stable enough for these applications. Typical requirements are for less than 50fs long term temporal stability between receivers, which is 0.05 degrees at 3GHz. Good results have been demonstrated for RF distribution schemes based on transmission of short pulses, but these require specialized free-space optics and high stability mechanical infrastructure. We report a method which uses only standard telecom optical and RF components, and achieves less than 20fs RMS error over 300m of standard single-mode fiber. We demonstrate stable transmission of 3GHz over 300m of fiber with less than 0.017 degree (17fs) RMS phase error. An interferometer measures optical phase delay, providing information to a feed-forward correction of RF phase

Effect of Ferulic Acid Esterase Enzyme Application on the \u3ci\u3ein Vitro\u3c/i\u3e Digestibility and \u3ci\u3ein Situ\u3c/i\u3e Rumen Degradability of Tropical Grasses

Tropical grasses are the primary staple diet of most of the domesticated ruminants in the tropical and subtropical regions of the world. However, dry matter (DM) digestibility (DMD) and intake levels of these C4 grasses are considerably low, partly because of high lignin contents. Ferulic acid also impedes fibre digestion in such forages due to formation of cross linkages with digestible xylans. Certain esterase enzymes have been shown to cleave ferulic acid cross linkages in wheat bran but no studies have examined whether such enzymes can be used to increase the digestion of tropical grasses. Therefore, the objective of this work was to evaluate the effect of a ferulic acid esterase preparation applied at different rates on the digestibility of C4 grasses
