Physiological and anatomical responses of Acacia koa (Gray) seedlings to varying light and drought conditions
No full textTrue leaves of Acacia koa (Gray) seedlings play a vital role in the early stages of seedling establishment, particularly in the Hawaiian archipelago where regeneration occurs under very heterogeneous light and moisture conditions. Given the importance of understanding seedling regeneration in the highly disturbed forests of Hawaii, we studied the growth, biomass allocation, physiological, and anatomical characteristics of A. koa seedlings with true leaves in response to three levels of light (low, intermediate, and high sunlight) and two levels of moisture regimes (100% field capacity, 20% field capacity) in a greenhouse experiment. With increasing light intensity, seedlings exhibited greater growth, biomass accumulation, intrinsic water-use efficiency, more foliar C, and higher stomatal density. Their leaflets were thicker, containing more palisade and spongy parenchyma. Low light intensity ameliorated drought-related effects of carbon assimilation on A. koa seedlings, while seedling growth of drought-stressed seedlings was reduced under intermediate and high sunlight. Our results suggest that true leaves of A. koa seedlings are adaptive when light is the only limiting environmental variable. The low adaptive capacity of true leaves to drought stress under high light intensity negatively affected seedling performance, which possibly explains environmental conditions under which phyllodes are likely to emerge
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
Evaluating resilience of tree communities in fragmented landscapes: linking functional response diversity with landscape connectivity
Full text linkAim Multiple agents of change increasingly impact functioning of forest ecosystems, for which management plans often ignore how local disturbances and habitat fragmentation jointly operate on ecological resilience at different scales. We examined sensitivity of functional response diversity (FD ) to variation in species diversity to predict ecological resilience to future disturbances across tree communities and evaluated the role of landscape connectivity in maintaining ecological resilience at the landscape scale. Location Centre‐du‐Quebec, Quebec, Canada. Methods We inventoried private forests and calculated FD and community‐weighted means to determine the extent to which forest‐use intensity affects ecological resilience. Subsequently, we constructed a regional map of FD , from which a spatial network was extracted. To assess potential impacts of fragmentation in maintaining FD at the landscape scale, we examined how the functional connectivity of the landscape, measured by the probability of connectivity (PC ), varied across a range of maximum seed dispersal distances. Lastly, we evaluated the importance of individual forest fragments in maintaining landscape FD by measuring the connectivity fractions of PC . Results Across tree communities, ecological resilience was low as FD increased sharply with species diversity. Forests with high FD were dominated by species with trait values associated with greater resilience to future anthropogenic disturbances rather than to future climate change. FD was maintained across the landscape by forest fragments acting as intermediate stepping stones in the transfer of seeds. Main conclusions We employed a novel approach based on spatial networks to extend the functional diversity concept from the local to the landscape scale. Our results suggest that seed dispersal over sufficiently large distances can maintain ecological resilience in fragmented landscapes and buffer changes in local‐scale FD . Otherwise, FD is maintained by local processes, meaning that ecological resilience of isolated forest fragments depends strongly on land use type and intensity
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
