In general, insects and arthropods polarizing: they either fascinate people, disgust people, or both, and they generate lots of questions. Museums are perceived as reliable sources of information and, as such, a go-to destination for the public to receive answers. Since its opening in 1990, the Montreal Insectarium has offered an entomological information service, allowing the public to send questions, photographs, and specimens for identification. All requests are answered by entomologists. Spatiotemporal variations in taxonomic, geographic, and thematic profiles of the 4163 requests received in 2010–2011 and 2017–2018 were analyzed. Requests came from 35 countries, and most of those requests came from Canada. The majority of requests were identification requests. Representing 25% of identification requests, the five most frequent species were the eastern dobsonfly Corydalus cornutus, the masked hunter Reduvius personatus, the giant water bug Lethocerus americanus, the western conifer-seed bug Leptoglossus occidentalis, and the Japanese beetle Popillia japonica. A comparison with the data from the citizen science platform iNaturalist shows that the EIS can be a valuable tool for invasive species detection. Frequent subjects included school projects, entomophagy (eating insects), and wasp and bee nests. Finally, we discuss the role of entomologists in providing scientific information but also in addressing common concerns regarding cohabitation with arthropods.

Data on the diversity, distribution, and main hosts of spider mites (Acari: Tetranychidae) are scarce in the Iberian Peninsula, particularly for Portugal, where only 21 species are recorded on the mainland and in the Azores and Madeira archipelagos. Moreover, the scientific information is mainly available in national publications, and difficult to access for international researchers. In this paper, we review the literature dealing with spider mites in mainland Portugal and the archipelagos of the Azores and Madeira, compiling and synthesizing the most relevant information on their distribution, hosts and pest potential. Further information was obtained by verifying slides in the acarological collection of the Instituto Nacional de Investigação Agrária e Veterinária (INIAV), the most important national collection, and by verifying mites collected on different plant hosts during the period 2018-2020. In total, we found records for 28 spider mite species in Portugal, comprising nine Bryobiinae and 19 Tetranychinae, and including new national records for Stigmaeopsis nanjingensis and Eotetranychus tiliarium. Additionally, we record a new exotic mite species for the mainland, Eotetranychus lewisi, which was found in two localities in the Algarve District on leaves of Euphorbia pulcherrima. This is the first record for continental Europe of an established population in outdoor conditions of this regulated quarantine pest. We also comment on the presence of seven species not reported by international taxonomic databases but already recorded from Portugal: Aplonobia histricina, Eotetranychus rubiphilus, Schizonobia sycophanta, Tetranychus kanzawai and Tetranycopsis horridus (at a national level), and Oligonychus perseae and Panonychus citri (for the mainland). New host records are given for Bryobia praetiosa, Petrobia (Tetranychina) harti, S. sycophanta, E. coryli, E. rubiphilus, Tetranychus kanzawai, Tetranychus lintearius, Tetranychus ludeni and Tetranychus turkestani.

Objective: The accelerating pace of biomedical publication has made retrieving papers and extracting specific comprehensive scientific information a key challenge. A timely example of such a challenge is to retrieve the subset of papers that report on immune signatures (coherent sets of biomarkers) to understand the immune response mechanisms which drive differential SARS-CoV-2 infection outcomes. A systematic and scalable approach is needed to identify and extract COVID-19 immune signatures in a structured and machine-readable format. Materials and Methods: We used SPECTER embeddings with SVM classifiers to automatically identify papers containing immune signatures. A generic web platform was used to manually screen papers and allow anonymous submission. Results: We demonstrate a classifier that retrieves papers with human COVID-19 immune signatures with a positive predictive value of 86%. Semi-automated queries to the corresponding authors of these publications requesting signature information achieved a 31% response rate. This demonstrates the efficacy of using a SVM classifier with document embeddings of the abstract and title, to retrieve papers with scientifically salient information, even when that information is rarely present in the abstract. Additionally, classification based on the embeddings identified the type of immune signature (e.g., gene expression vs. other types of profiling) with a positive predictive value of 74%. Conclusions: Coupling a classifier based on document embeddings with direct author engagement offers a promising pathway to build a semi-structured representation of scientifically relevant information. Through this approach, partially automated literature mining can help rapidly create semi-structured knowledge repositories for automatic analysis of emerging health threats.

Over the past decade, the issue of uncontrolled growth of unsystematic information in Internet has remained acute for the scientific community. The problem of finding relevant information related to the distribution and autonomy of scientific information resources remains. A priority in the field of centralized access to the key scientifically significant sources of information is the creation of a united information space (UIS). The study aims to identify the main models to form systems integrating distributed information resources, and as a result to determine the structure of UIS formation in a research library. Two models were considered and analyzed in the study: a meta-aggregator and an integrated electronic library. During the analysis, elements, structure and a set of functions for users and employees of a research library are revealed for each model. The study allowed the drawing of the following conclusions:• The choice of a model for the UIS formation depends mostly on the formulation of tasks, the solution of which is the purpose of creating a system, as well as on the technological potential of the organizations involved in the process.•Multifunctionality of the system allows simultaneous use of the above-mentioned formation models.• Adding the element of interactivity to the structure of UIS of the research library will allow timely monitoring of changes in the information needs of scientists, reduction of time, labor and financial costs of both the library and a user. The article presents the criteria for choosing a model. For the first time the optimal effective structure of the UIS in the research library is described.

Abstract The Danube Delta is a relatively young territory, formed about 14,000 years ago. It has quadruple status: Biosphere Reserve, Ramsar site, UNESCO World Heritage site, Natura 2000 site. Water and human activities are the most important factors influencing the flora of this area, including the penetration and spread of alien plants. The main goal of our research in this area was to inventory the alien plants and to identify those species which are invasive and potentially invasive in the natural and semi-natural ecosystems in order to propose measures for their prevention and mitigation. An inventory of these plants, conducted between 2009 and 2012 and based on bibliography and field research, comprises over 160 taxa. About half of them originated from America and less than a quarter of them from Asia. A relatively high number of species have unknown status in the Danube Delta; they were reported only from one or two localities and we did not record them during our extensive field work. In this category we also included some taxa of Xanthium without a very clear taxonomy. The taxa recorded as casual are usually ornamental plants escaped from cultivation; however among them there are some species which are known as invasive in other areas of Romania, as well as in Europe. There are 26 naturalised species, two of which established here over one hundred years ago. 37 invasive species were identified, many of them recorded in natural or seminatural places. In order to prevent and mitigate the spread of plants recognised as invasive, we propose the implementation of some measures such as providing relevant information to local communities and raising awareness about the damages caused by the alien species, and promoting further research on alien plant species in this protected area.

This chapter deals with scientific information about the wild socioeconomic plants used by the local inhabitants of the Champawat district of Uttarakhand for the enhancement of their livelihood. During this entire study, it was observed and documented that poor rural people of this area are educationally and financially backward, and they do not have any permanent source of income; due to this reason they are unable to fulfill their necessary requirements. Therefore, they are totally dependent on various forest ecosystem services, viz., selling prepared herbal medicines, wild edible fruits, and wild ornamental plants, etc., which shares approximately 45-50% of their total annual income and plays a vital role for the upliftment of their livelihood. During this research work, a total of 63 plant species belonging to 58 genera under 46 families have been documented, which are being used as livelihood resources by the locals of this area.

Purpose – This study aims to investigate how the transition from print to electronic scholarly communication has affected faculty’s information behaviour and their perception of academic libraries. Design/methodology/approach – An online survey was distributed among academics affiliated to the member universities of the Consortium of University Services of Catalonia. A total of 2,230 replies were received. Findings – Journal articles are the most relevant information resource used for research and teaching purposes. Databases are the preferred starting point for bibliographic searches, although a significant proportion of scholars rely on Internet search engines. The main source for gaining access to documents is libraries, followed by free materials available online. Scholarly journals are the preferred channel for disseminating research outputs, with the open access being a factor of marginal interest when deciding where to publish. Originality/value – The results of this study should be useful to guide policies regarding scientific information and research and, more specifically, policies regarding academic libraries.

O conhecimento científico-tecnológico oriundo de pesquisas visa a solucionar os problemas da sociedade e contribuir para seu desenvolvimento. A partir disso, o processo de comunicação científica, através de canais formais ou informais, torna-se essencial para que a evolução do estado da arte de uma área seja sempre constante. Porém, nem sempre as informações são encontradas nos meios tradicionais de publicação de conhecimento, fazendo com que a literatura cinzenta torne-se uma fonte valiosa para diversas áreas do conhecimento. O desenvolvimento e a evolução das novas tecnologias de informação garantem a essa comunicação um caráter ágil e dinâmico, permitindo que a literatura cinzenta avance para um reconhecimento de sua importância no meio acadêmico. Portanto, faz-se necessário o gerenciamento desse tipo de literatura, que possibilita uma alternativa aos meios tradicionais de aquisição de informação científica. A proposta de criar um ambiente de recuperação de informação e gerenciamento da literatura gerada em encontros de estudantes desenvolve-se a partir da ideia de que, muitas vezes, é possível antecipar tendências que só seriam perceptíveis quando da publicação das mesmas pesquisas em meios já consolidados, muitas vezes ocasionando uma perda de informações existentes apenas em seu andamento, subtraídas quando da redação de artigos ou livros. Assim, a proposta de utilização do programa Open Conference Systems possibilita não somente uma maior agilidade e dinamismo na organização de eventos, tendo também como objetivo a possibilidade para a criação de um ambiente digital em que trabalhos apresentados nos eventos estudantis de biblioteconomia, documentação, ciência e gestão da informação, permitindo uma interação entre pesquisadores, tornando-se uma alternativa para publicação, exercendo função memorial para os eventos estudantis da área e constituir uma fonte de informação relevante para a comunidade.AbstractThe scientific-technological knowledge produced by the researches aims at solving problems of the society and contributes to its development. From this on, the process of scientific communication, through formal or informal channels, is essential for the constant evolution of the state of the art of an area. However, not always the information is found in the traditional means of publication, this way, gray literature is a valuable resource for many areas of knowledge. The development and evolution of new information technologies ensure to this kind of communication a dynamic and agile character, allowing the gray literature to reach recognition by the academia. Therefore, it is necessary to manage this type of literature as an alternative to the traditional means of acquiring scientific information. The proposal to create an environment of information retrieval and management of the literature generated in students’ meetings starts from the idea that it is often possible to anticipate trends, that would only be noticed when established means of dissemination publish such researches, often causing a loss of information existing only when the research is in progress or is subtracted when writing articles or books. Thus, the proposed use of the Open Conference Systems program not only allows greater flexibility and dynamism in the organization of events, but also, the development of a digital environment where works presented in the students’ events on library, information science and information management could be posted, allowing interaction among researchers, becoming an alternative to publication, assuming a memorial role for students’ events in the area, besides being a source of relevant information to the academic community.

Beekeeping is one of the promising ventures for economically poor families in Nepal. Knowledge about the bee flora of a certain area is very crucial for the farmers. A study was conducted in mid hills of Central Nepal during 2003-04 and 2008-09 to monitor the common plant species visited by bees with their visiting time and seasons. The flowering period of those plant species were also observed. Observations were made on the bees’ activities on flowers of different plant species. Relevant information was also collected through informal key informant interviews. The plant species visited by the bees and the bee species (mainly Apis cerena with some Apis melifera) themselves were collected, preserved and identified. Plants were categorized as major, medium and minor sources of pollen and/or nectar. The pollen and nectar statuses in different plants were also determined. A total of 158 plant species were identified as main bee flora in the study area. Among them, 19 species were horticultural plants, 42 species were crop plants, 15 species were ornamental plants and 82 species were wild plants. In total, 38 species were recognized as major, 35 as medium and 30 as minor sources for both nectar and pollen. Months from March to May and August to October were the honey flow periods. Species of Brassica, Citrus, Pyrus, Berberis, Rubus, Callistemon, Bombox and Artemisia were some of the important plants which bloomed during those months. Winter (mid November to January) and rainy (June and July) seasons were identified as the dearth periods for bees to collect honey. Some of the plants that bloom during winter were Pisum sativum, Ipomoea batata and Eupatorium sp. Similarly, Lagerstroemia sp., Impatiens balsamina, Sesamum indicum, Zea mays and many cucurbits bloomed during rainy season. Study has shown that mid-hills of Central Nepal is rich in bee flora and has great potential for beekeeping as many plants bloomed even in dearth periods.doi: http://dx.doi.org/10.3126/botor.v8i0.5558 Botanica Orientalis – Journal of Plant Science (2011) 8: 45-56
