Effects of shoreline armouring and overwater structures on coastal and estuarine fish: opportunities for habitat improvement
Authors: Munsch Stuart H. , Cordell Jeffery R. , Toft Jason D. 
Published: April 2017

Summary

Nearshore ecosystems are increasingly recognized as critical habitats for fish of cultural, ecological and economic significance. These ecosystems are often densely inhabited by juvenile fish, highly productive and refuges from predation, leading ecologists to characterize them as nurseries. However, nearshore ecosystems are being transformed globally to support demands of growing coastal populations. Many shorelines are modified by armouring (e.g. seawalls, riprap) that minimizes erosion, and overwater structures (e.g. piers, docks) that facilitate waterfront use. These modifications affect the ecology of nearshore systems by restructuring, eliminating and shading shallow waters.

Here, we review literature examining effects of armouring and overwater structures on coastal and estuarine fishes, and discuss how research and management can coordinate to minimize negative effects.

Along armoured shorelines, fish assemblages differed from unarmoured sites, fish consumed less epibenthic and terrestrial prey, beach spawning was less successful and fish were larger. Under large overwater structures, visually oriented fish were less abundant and they fed less. Shade from overwater structures also interrupted localized movements of migratory fish. Thus, shoreline modifications impaired habitats by limiting feeding, reproduction, ontogenetic habitat shifts from shallow to deeper waters and connectivity.

Research suggests that restoring shallow waters and substrate complexity, and minimizing shading underneath overwater structures, can rehabilitate habitats compromised by shoreline modifications.

Synthesis and applications. Shoreline armouring and overwater structures often compromise fish habitats. These threats to nearshore fish habitats will become more severe as growing coastal populations and rising sea levels increase demands for shoreline infrastructure. Our ability to assess and rehabilitate nearshore fish habitats along modified shorelines will be enhanced by: focusing research attention on metrics that directly indicate fish habitat quality; implementing and evaluating shoreline features that repair compromised habitat functions within human‐use constraints; collating natural history knowledge of nearshore ecosystems; and embracing the socio‐ecological nature of habitat improvements by educating the public about conservation efforts and fostering appreciation of local nearshore ecosystems. Actions to reduce impacts of shoreline modifications on fish are particularly feasible when they align with societal goals, such as improving flood protection and providing spaces that facilitate recreation, education, and connections between people and nature.

Summary

Changing climate threatens the structure and function of saltmarshes, which are often severely degraded by other human perturbations. Along the Mediterranean coastline, increasing temperature and decreasing rainfall have been hypothesised to trigger habitat shifts from perennial grasses to annual succulents in fragile saltmarsh ecosystems, such as those fringing the North Adriatic coastline.

We used manipulative field experiments to investigate the effects of increased temperature, decreased precipitation and increased inundation period associated with rising sea levels on the dominant species in the lower marsh, the perennial grass Spartina spp. and the annual succulent Salicornia veneta.

At ambient inundation, the combined effects of increased temperature and decreased precipitation enhanced soil temperature and decreased soil moisture, resulting in an increased number of plants, height and live biomass of S. veneta, as well as greater dead biomass of Spartina spp. compared with current conditions. Increased inundation reduced the soil redox potential, and resulted in losses of both Spartina spp. and S. veneta, but these negative effects were much more pronounced for S. veneta. An inundation tolerance test confirmed that S. veneta is significantly more vulnerable to rapid increases in inundation than Spartina spp.

We conclude that at current inundation, the increasing drought conditions in the North Adriatic Sea are favouring the spread of the annual succulent S. veneta. The increasing spread of these succulents could reduce the future capability of the system to respond to projected increasing sea levels, as S. veneta is highly vulnerable to increased inundation.

Synthesis. Our results highlight the complex interactions between different components of changing climate. Management strategies for saltmarshes in the Mediterranean and other microtidal locations facing similar changes in climate should focus on maintaining the freshwater and coastal channels free from blockages to ameliorate the effects of episodic drought/heatwave conditions and increasing the sediment supply and preventing coastal squeeze to enhance the resilience of the system to the continuous threat of sea level rise.

AbstractEstimating the postmortem interval (PMI) is very important in the forensic sciences. Although many approaches have been used for estimating the PMI, accurate PMI calculations are still difficult. In this study, four Sprague Dawley (SD) rats were sacrificed by suffocation, and muscle samples were collected by dissection at various time intervals (0, 48, 96, and 144 h) after death. All samples were probed using matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOFMS) to obtain molecular images and data for principal component analysis (PCA). The results showed that the peaks at m/z 1511, 1543, 1564, 1586 clearly decreased in intensity from 0 to 144 h postmortem and that the time groups were separated from each other on the PCA score plot. The prediction model showed high recognition capability (95.93%) and cross‐validation (83.72%). Our work suggests that MALDI‐TOF MS can be used to determine the PMI.
Relationship between endobronchial ultrasound‐guided (EBUS)‐transbronchial needle aspiration utility and computed tomography staging, node size at EBUS, and positron emission tomography scan node standard uptake values: A retrospective analysis
Authors: Marchand Clare , Medford Andrew R.L. 
Published: April 2017

BackgroundEndobronchial ultrasound‐guided transbronchial needle aspiration (EBUS‐TBNA) diagnoses and stages mediastinal lymph node pathology. This retrospective study determined the relationship between EBUS‐TBNA utility and non‐small cell lung cancer (NSCLC) stage, lymph node size, and positron emission tomography (PET) standard uptake values (SUV), and the utility of neck ultrasound in bulky mediastinal disease.MethodsData of 284 consecutive patients who had undergone EBUS‐TBNA was collected. Two hundred patients had suspected NSCLC, with 148 confirmed NSCLC cases. The diagnostic utility of EBUS‐TBNA was determined according to NSCLC stage, EBUS lymph node size, PET SUV, use in distal metastases, and mutation testing. The utility of neck ultrasound for N3 disease was calculated in patients with bulky mediastinal disease.ResultsEBUS‐TBNA was well tolerated with 97% sensitivity in distant metastatic disease, avoiding the need for distal metastases biopsy in 81% of cases. It had equivalent diagnostic accuracy in all NSCLC stages and in lymph nodes <10 mm, <20 mm or >20 mm (sensitivity >92% in all cases), with no mutation testing failures. EBUS‐TBNA had 33% sensitivity in PET indolent (SUV < 4) nodes and 79% sensitivity in PET active nodes (SUV > 4). EBUS‐TBNA diagnosed 12 cases of lymphoma without flow cytometry.ConclusionsThe use of EBUS‐TBNA meant that distant metastatic biopsy was avoided in 81% of cases, performing well irrespective of cancer stage, node size, and facilitating mutation testing. Neck ultrasound failed to detect N3 disease in patients with bulky mediastinal disease. EBUS‐TBNA had a sensitivity of 33% for metastases in PET negative nodes, highlighting PET limitations.
Spatio‐temporal connectivity: assessing the amount of reachable habitat in dynamic landscapes

Published: April 2017

SummaryLandscape heterogeneity and habitat connectivity affect species movements, playing an important role in determining the likelihood of species persistence. However, landscape connectivity is usually evaluated using static snap‐shots, which do not account for the sequential interactions among habitat patches through time.We developed a network‐based model of landscape dynamics, and corresponding connectivity metrics, to account for the reachable habitat across space and time. We illustrate the behaviour of these metrics, using fragmented forested landscapes in the Atlantic Forest of Brazil. We parametrized the models using the dispersal capacities of selected bird and small mammal species.We found that when considering spatio‐temporal links, connectivity is estimated to be on average 30% higher (with a maximum of 150% higher) than what is estimated from purely spatial models. This higher degree of spatio‐temporal connectivity arises due to connections through temporal stepping‐stone patches that appear (habitat gain) and disappear (habitat loss) over time. Species with short dispersal distances (<1000 m) particularly benefited from the spatio‐temporal connections. The contribution of spatio‐temporal connectivity to habitat reachability increased with higher habitat loss rates. Moreover, it depended on the amount of habitat in the landscape, being higher at intermediate habitat amounts (∼30%).We showed that accounting for spatio‐temporal connectivity is critical for understanding ecological patterns and processes in dynamic landscapes, and that a series of purely spatial connectivity metrics underestimates the actual connectivity patterns across time. The proposed spatio‐temporal connectivity approach and metrics can be applied to evaluate the effective connectivity patterns and trends in a variety of dynamic landscapes, avoiding the potential overestimates of population isolation and extinction probabilities that may result from widely used purely spatial connectivity models.
Dentists’ restorative decision‐making and implications for an ‘amalgamless’ profession. Part 4: clinical factor
Authors: Alexander G , Hopcraft MS , Tyas MJ , Wong RHK 
Published: April 2017

AbstractBackgroundThe Minamata Convention embodies a worldwide reduction in the production and use of mercury and mercury‐containing products and processes, including a phase‐down of dental amalgam. This will change the approach to the use of direct restorative materials in the near future. There is little research as to the influence of clinical factors on dentists’ decision‐making which may be of use when determining the impact of any change.MethodsAn online survey relating to aspects of and attitudes to the use of direct restorative materials was distributed to all dentists who were members of the Australian Dental Association and/or members or fellows of the Royal Australasian College of Dental Surgeons. Data were statistically analysed.ResultsThere were 408 respondents to the survey. Eighty‐seven per cent of respondents (strongly) disagreed that amalgam was a technically more difficult material to place compared with resin composite, 82% (strongly) disagreed that placement time for amalgam was longer than that for resin composite and 69% (strongly) disagreed that amalgam was more difficult to finish than resin composite. Eighty‐three per cent of respondents stated they were confident in their ability to place amalgam restorations. Where physical properties were of importance, indirect restorations were preferred (e.g. parafunction) 54%. The factors considered most important when choosing a direct restorative material included moisture control and aesthetics; least important factors were cost and time to place.ConclusionsThere is consensus that amalgam is not more technically difficult to use, place or finish than resin composite and vice versa. There is recognition that both amalgam and resin composite have limitations in terms of physical properties. When choosing a direct restorative material, clinical factors considered to be of greatest importance are moisture control, aesthetics and the need to apply minimally invasive approaches. There is little difference in the opinions of users and non‐users of amalgam with respect to these findings.

AbstractAimSunitinib is a first‐line treatment option for metastatic renal cell carcinoma (mRCC) funded by the Australian Pharmaceutical Benefits Scheme. Toxicities are common with the standard schedule leading to alternative dosing schedules to be suggested. We reviewed Australian treatment practices to evaluate the safety and outcomes of patients on a 2 weeks on, 1 week off treatment schedule (2/1).MethodsWe performed a retrospective review of 63 patients with mRCC treated with first‐line sunitinib on a 2/1 schedule at four Australian centers.ResultsForty‐six patients (73%) initiated sunitinib on the 2/1 schedule whereas 17 (27%) switched from the 4/2 schedule due to toxicity. Three progressing on a 4/2 schedule tolerated up‐titration of their dose with a clinical and radiological response on the 2/1 schedule. The median duration of treatment was 31.9 months; median duration of treatment on the 2/1 schedule in patients changing from 4/2 was 11.5 months. Few (6.3%) ceased due to toxicity. Median overall survival was 37.2 months.ConclusionIn this retrospective review of the 2/1 sunitinib schedule, time on treatment with clinical benefit exceeded the overall survival times seen in the phase III trials utilizing the 4/2 schedule. Overall survival also exceeded that seen in these trials. Few patients ceased due to toxicity. The 2/1 schedule appears to be an acceptable schedule to use in selected patients with mRCC both at initiation of first‐line treatment and in those intolerant to the 4/2 schedule.

BackgroundProlongation of the QT on the surface electrocardiogram can be due to either genetic or acquired causes. Distinguishing congenital long QT syndrome (LQTS) from acquired QT prolongation has important prognostic and management implications. We aimed to investigate if quantitative T‐wave analysis could provide a tool for the physician to differentiate between congenital and acquired QT prolongation.MethodsPatients were identified through an institution‐wide computer‐based QT screening system which alerts the physician if the QTc ≥ 500 ms. ECGs were retrospectively analyzed with an automated T‐wave analysis program. Congenital LQTS was compared in a 1:3 ratio to those with an identified acquired etiology for QT prolongation (electrolyte abnormality and/or prescription of known QT prolongation medications). Linear discriminant analysis was performed using 10‐fold cross‐validation to statistically test the selected features.ResultsThe 12‐lead ECG of 38 patients with congenital LQTS and 114 patients with drug‐induced and/or electrolyte‐mediated QT prolongation were analyzed. In lead V5, patients with acquired QT prolongation had a shallower T wave right slope (−2,322 vs. −3,593 mV/s), greater T‐peak‐Tend interval (109 vs. 92 ms), and smaller T wave center of gravity on the x axis (290 ms vs. 310 ms; p < .001). These features could distinguish congenital from acquired causes in 77% of cases (sensitivity 90%, specificity 58%).ConclusionT‐wave morphological analysis on lead V5 of the surface ECG could successfully differentiate congenital from acquired causes of QT prolongation.
Introduction: Critical Agrarian Studies in Theory and Practice
Authors: Edelman Marc , Wolford Wendy 
Published: April 2017

AbstractIn this introductory article we argue for renewed attention to life and labor on and of the land—or what we call the field of Critical Agrarian Studies. Empirically rich and theoretically rigorous studies of humanity's relationship to “soil” remain essential not just for historical analysis but for understanding urgent contemporary crises, including widespread food insecurity, climate change, the proliferation of environmental refugees, growing corporate power and threats to biodiversity. The article introduces an innovative and varied collection of works in Critical Agrarian Studies and also examines the intellectual and political history of this broader field.
High intensity focused ultrasound for the treatment of adenomyosis: selection criteria, efficacy, safety and fertility
Authors: Zhang Lian , Rao Fangwen , Setzen Raymond 
Published: April 2017

AbstractAdenomyosis is a disorder of uterus in which endometrial glands and stroma are present within the uterine musculature. The main clinical manifestations are dysmenorrhea and menorrhagia. Adenomyosis has a great impact on both the quality of life and fertility of women. The treatment of adenomyosis remains an immense challenge. Relevant articles were searched through MEDLINE and PubMed between 2000 and March 2017. The search terms of adenomyosis, magnetic resonance imaging (MRI) features of adenomyosis, high intensity focused ultrasound (HIFU), ultrasound‐guided HIFU and MRgFUS were used. There were no language restrictions. HIFU is a non‐invasive local thermal ablation technique which has been used in the treatment of both focal and diffuse adenomyosis. Several case studies have demonstrated that HIFU presents low rate of minor and/or major complications and, at the same time, a long symptom‐relief period. Multiple factors such as the enhancement type of the adenomyotic lesion, volume of the adenomyotic lesions, number of hyperintense foci on T2WI, location of the uterus, location of adenomyotic lesions, thickness of the abdominal wall and distance from the skin to the adenomyotic lesions contribute to the efficacy of HIFU. Consequently, based on these contributing factors, specific and strict selection criteria have been used to achieve higher efficacy. Thus, patients with pelvic endometriosis, adhesions between the bowel and the uterus, or an abdominal surgical scar wider than 10 mm, are not suitable for HIFU treatment. Moreover, HIFU‐treated patients with adenomyosis, who wished to conceive, showed high conception and live birth rates. HIFU is a new and promising treatment option for patients with adenomyosis, but its efficacy, safety, cost‐effectiveness and fertility outcome must be evaluated by randomized controlled trials.
The Effect of Ultimate Ownership on the Disclosure of Environmental Information
Authors: Wang Peng , Wang Fangjun , Hu Nan 
Published: April 2017

AbstractThis study empirically examines whether environmental information disclosure (EID) is influenced by the characteristics of a firm's ultimate owners. Based on the EID of publicly listed firms in China, we qualitatively measure the quality of EID of each firm and link those quality scores to firm characteristics to understand the determinants of EID. We further link the EID scores to market valuation of the firm through the Ohlson valuation model to understand whether the market appreciates EID. Our results show that EID is more likely for government‐controlled firms, firms with less hierarchy in their ultimate ownership and firms with more discrepancy between voting rights and cash flow rights. Our results also indicate that the stock market appreciates environmental issues and that EID itself, as well as disclosure quality, is associated with a higher market valuation. Our results still hold with the endogeneity issue controlled.
Fair Value Measurement and Mandated Accounting Changes: The Case of the Victorian Rail Track Corporation
Authors: Abbott Malcolm , Tan‐Kantor Angela 
Published: April 2017

AbstractVicTrack in the State of Victoria in Australia began using fair value to value its assets in 2011. In doing this the company encountered the difficulties normally associated with valuing long‐lived assets that are specific to their use. In this paper, a case study is presented centred on VicTrack in order to provide information on the basic difficulties of determining the fair value of assets that are long‐lived, specific‐to‐use and in markets that are incomplete; and to better understand some of the implications of the switch from historical costs to fair value.
The Public Accountability Value of a Triple Bottom Line Approach to Performance Reporting in the Water Sector
Authors: Tan Lai Ken , Egan Matthew 
Published: April 2017

AbstractGlobal water resources are subject to increasing supply constraints. We respond by exploring how novel public sector performance reporting can service public accountability. Here our focus is an exploration of the drivers and utility of a unique ‘sustainability’‐focused, publicly disclosed, performance reporting initiative undertaken by a water agency in Australia. Semi‐structured interviews were conducted with a range of individuals from 2013 to 2014. A disclosure index was also constructed to assess the quality of the disclosures. While the key purpose of the reports was to provide managerial accountability with intra‐governmental stakeholders, they were also drawn on to serve a secondary public accountability purpose with external stakeholders. We argue that the prioritisation of internal stakeholders could threaten utility for public accountability purposes. However, in this case, the reports were also found to be largely relevant to the general public. The study demonstrates that reporting developed for managerial accountability purposes can be designed and targeted also to contribute usefully to ancillary public accountability objectives. Our engagement with the public sector to explore the role and effectiveness of novel reporting strategies in support of sustainability and accountability objectives is topical, and contributes to understanding potential solutions in other contexts.
