Ecological Community Changes and Ecosystem Functioning During Structured Wetland Development
Full text linkSaltmarshes provide important ecosystem services, including protection from tidal inundation, grazing for livestock, resources for birds and breeding grounds for fish. After a long history of saltmarsh reclamation there is now emphasis on restoration of existing or destroyed saltmarshes to provide dynamic coastal defences providing ecosystem services. The engineering technique of Managed Realignment (MR) is a popular method of restoration where existing coastal defences are deliberately breached. The process of change associated with MR, including the influences of starting state, construction, and saltmarsh community structure changes require further study to provide guidelines for optimal restoration practices. Here, the ecological changes during the early stages of saltmarsh restoration via MR at Steart Marshes in Somerset, UK are studied. Common Standards Methods were used to monitor vegetation and invertebrate community composition changes from pre-breaching (September 2014) through 4 years of tidal regime post-breaching. Soil and sediment characteristics, and soil accretion were studied at the same time. All data were collected from permanent sample plots. Changes were compared with a managed brackish site (Otterhampton Marsh) with a similar starting state, and a mature SSSI saltmarsh in Bridgwater Bay was treated as a ‘target state’. Soil characteristics included soil moisture, pH, electrical conductivity, soil organic carbon, nitrate-nitrogen, ammonium-nitrogen and phosphate-phosphorus. Changes of these were compared to the target state and the managed brackish site. The National Vegetation Classification (NVC) scheme was partly used to assess vegetation communities, and multivariate methods including cluster analysis and ordination were used to assess changes of flora, invertebrates, and soil characteristics. Saltmarsh vegetation colonised a former pasture location more rapidly than a former arable location and was slowest in the managed brackish location. Colonisation by invertebrates and soil characteristics followed a similar pattern. The most abundant invertebrate species were identified to species and quantified, and their abundance on Steart Marsh was compared to the mature SSSI saltmarsh and brackish site. The three most abundant species overall were Orchestia gammarellus, Campiglossa plantaginis, and the invasive planthopper, Prokelisia marginata. C. plantaginis was positively correlated with the abundance of colonising Aster tripolium, and P. marginata had a positive relationship with colonising Spartina anglica. It is likely that soil compaction, partly caused by pre-breach engineering, influenced differences in soil characteristics between study sites and in plant and invertebrate colonisation, principally due to the prevalence of standing water associated with anaerobic conditions. Compaction and land height (AOD) influenced plant colonisation across all sites and soil moisture and electrical conductivity influenced colonisation by plants and invertebrates on Steart Marsh and Otterhampton Marsh after the breach. Soil carbon storage was greatest in the former pasture site. Vegetation, invertebrates and soil characterstics in the former pasture site on Steart Marsh started to resemble that of the SSSI saltmarsh three years after tidal inundation commenced, and overall the results indicate that restoration is influenced by former site use and engineering practices involved in Managed Restoration
Second-harmonic generation at the liquid/air interface
No full textThe technique of second-harmonic generation has been used to investigate the interfacial properties of several systems. These include H2O/air, NaCl(aq)/air, H2SO4(aq) / air, phenol(aq)/air and the surfaces of various specially prepared metals. Several different laser systems were used during the course of this work providing a range of frequencies, powers, and repetition rates.The temperature dependence of the second-harmonic response from the H2O/air interface was investigated from 20 to 70oC. Over his temperature range, the magnitude of the second-harmonic signal was found to decrease by ~20%. In addition, evidence was found for an angular distribution, of the interfacial molecules, the average of which tilts further from the surface normal as the temperature increases. The indication is an augmentation of the orientational distribution of the surface molecules, which can be accounted for as a result of increased thermal agitation. NaCl was used to study the effects of adding an electrolytic substance on the interfacial properties of the H2O/air system. Although an increase in the second-harmonic response was detected with increasing NaCl concentrations, the components of the second-order surface susceptibility showed no significant fluctuation.Concentration and temperature dependence studies of the second-harmonic response, were performed on the H2SO4(aq)/air interface. The results showed a significant dependence of the second-order surface susceptibility on acid concentration. Three phases of behaviour were discovered at low, equi-molar, and high molarities. Increasing temperature provided evidence for a shifting of the various phases to higher concentrations.Polarisations dependence studies were performed on the phenol(aq)/air interface for concentrations up to 0.5M. The magnitude of the second-harmonic follows the increase in surface coverage, as measured by neutron reflection experiments [Z.X.Li, R.K.Thomas, A.R.Rennie and J. Penifold, J. Phys. Chem B, 102, 185-192, (1998)]. The average molecular orientation of the interfacial phenol is found to remain constant over the concentration range 0.1 to 0.5 M.The surface of mesoporous and continuous platinum films was investigated with polarisation dependence scans for the second-harmonic signal. The result was a variation of detected signal from rotation of the sample. There is evidence that the gold substrate influenced the results of the scans of the mesoporous samples. The success of this experiment was hindered by the inability to align consistently with molecular domains.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Searching for patterns in the electrical conductivity signal of stream waters
No full textObjective: Develop an algorithm to decompose streamflow electrical conductivity signal into its “harmonics”, i.e. into the specific contribution of different ion species. Level: BS, Masters Description: The electrical conductivity (EC) of an aqueous solution is the capacity to transmit electrical current through the movement of charged ions. Typical major ions in natural waters are: H+, Na+, Ca2+, Mg2+, K+, Cl−, SO2−, NO− and HCO−. For a number of environmental applications, EC can be expressed as a linear combination of the concentrations of the major solutes dissolved in water. As EC can be measured continuously through simple sensors, there is great potential in using it for environmental monitoring. However, separating the contributions of individual solutes from the bulk measured signal can be challenging. One opportunity is that of investigating high-resolution datasets, where such contributions can be measured, and search for characteristic signatures that allow developing a predictive algorithm to estimate solute concentration from EC measurements. Data Example: The figure shows an example of EC decomposition obtained for the UHF dataset, Plynlimon, Wales. Chloride (Cl−) and sodium (Na+) are responsible for most of the EC signal, while potas- sium (K+) and nitrate (NO−3) have almost negligible contributions. Almost all the elements have strong dependence on flow which causes either peaks (as for hydrogen (H+)) or sharp depressions. Tasks: 1 - basic statistical analysis of existing water-quality datasets 2 - characterisation of elements contribution to EC, using additional information such as river flow and temperature 3 - development of algorithm(s) to invert equation 1 and estimate solute concentration from EC measurements Type of Work: 50% design and 50% development.

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
