Morphological and biological characteristics of Burara oedipodea (Swainson) (Lepidoptera: Hesperiidae) on Hiptage benghalensis (Malpighiaceae)
No full textHiptage benghalensis (L.) Kurz is a woody vine species belonging to the family Malpighiaceae, native to India, Southeast Asia, and China (POWO, 2024). Owing to its attractive and fragrant flowers, it has been introduced and grown as an ornamental plant in many parts of the world, and has subsequently become invasive in all introduced areas, including Réunion, Mauritius (Friedmann, 2011), northern Australia (Queensland) (Csurhes, 2016; Weeds of Australia, 2016), Florida and Hawaii (Randall, 2002; Starr et al., 2003), and the Seychelles (Senterre & Dine, 2022). This plant species has been listed among the world's 100 most invasive species, posing a significant threat to native biodiversity (IUCN-International Union for Conservation of Nature; ISSG-Invasive Species Specialist Group). Réunion Island (France) - a biodiversity hotspot of the world (Myers et al., 2000). On the island, the species forms impenetrable thickets; vines choke large trees, cover plant canopies, block light, and inhibit native vegetation growth, leading to the establishment of monospecific colonies (Ahmed et al., 2017; Tassin et al., 2006; E. Rivière, pers. comm., 2023), threatening rare native plants (Robert et al., 2015; Ahmed et al., 2017).
To manage H. benghalensis in Réunion, various control methods, including mechanical, chemical, and combined approaches, have been tested (Hivért, 2003). A similar management attempt was also conducted in Australia (Vitelli et al., 2009); however, these methods were proved to be unfeasible due to plant regrowth, high costs, labor intensity, and long-term ineffectiveness. Given these challenges, biological control has been considered a promising, sustainable, and environmentally friendly solution. Among many types, classical biological control (CBC) refers to the deliberate release of a non-native natural enemy to sustainably reduce the population of a specific pest over the long term (Eilenberg et al., 2001; Kenis et al., 2017), is one of the most widely applied strategies for managing invasive species (Meyers & Cory, 2017). Therefore, a CBC program was initiated in its native range, Vietnam, in 2022 to search for potential arthropods and microorganisms to manage this plant in Réunion (Lam et al., 2023). Surveys recorded various arthropods on H. benghalensis and other species of the genus Hiptage, among which larvae of Burara oedipodea (Swainson) were commonly found and caused significant damage.
Burara oedipodea belongs to the genus Burara, that comprises two species and five subspecies. It was first described in 1820. It has been repeatedly recorded feeding on H. benghalensis (Young, 1993; Swinhoe, 1912 in Chiba, 1995), all records coming from the plant’s native range (GBIF.org, 2025). Besides, it has also been recorded feeding on a single additional plant species, Combretum latifolium (Chiba, 1995), which belongs to the family Combretaceae. Given this limited host range, Burara oedipodea is classified as a narrow oligophagous species. This dataset presents morphological characteristics of B. oedipodea reared on H. benghalensis plants
Interannual variability of glacier basal pressure from a 20 year record
No full textBasal pressure has been recorded at the Svartisen Subglacial Laboratory, northern Norway, for 20 years, and is measured by load cells installed at the ice–rock interface under ∼200 m of glacier ice. Synchronous pressure variations between load cells are investigated as evidence of stress redistribution and hydrological bed connectivity. A running Pearson correlation is used to study the temporal variation in the response of several sensors. By studying the nature of this correlation as well as the correlation between sensor pairs, it is possible to investigate the evolution of the degree of synchronous response, and to some extent basal connectivity, at the glacier bed. Persistent seasonal variations associated with the melt season are observed throughout the measurement period, indicating dependence on surface hydrological forcing. Overlying this pattern, specific years with longer periods of positive and negative correlation of pressure between sensors are presented to show contrasting interannual variability in basal pressure. An anticorrelated connectivity is associated with a local increase in the rate of daily subglacial discharge, and is caused by load transfer or passive cavity opening. Stable weather appears to enhance connectivity of the sensors, which is attributed to the development of a persistent drainage system and stress redistribution
Complete Genome Sequences of Six Copper-Resistant Xanthomonas Strains Causing Bacterial Spot of Solaneous Plants, Belonging to X. gardneri, X. euvesicatoria, and X. vesicatoria, Using Long-Read Technology
Full text linkXanthomonas vesicatoria, Xanthomonas euvesicatoria, and Xanthomonas gardneri cause bacterial spot disease. Copper has been applied since the 1920s as part of integrated management programs. The first copper-resistant strains were reported some decades later. Here, we fully sequenced six Xanthomonas strains pathogenic to tomato and/or pepper and having a copper-resistant phenotype.EEA Bella VistaFil: Richard, Damien. CIRAD, UMR PVBMT; Francia.

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
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
