First trials exploring the potential of phytoseiid mites in managing lychee erinose mite, Aceria litchii (Keifer) (Acari: Eriophyidae), infestations on lychee plants.

Phytoseiid mites have been frequently found in association with the lychee erinose mite, Aceria litchii, on lychee plants in Brazil, suggesting that they are promising candidates as biological control agents against this pest. Here, we investigated whether phytoseiids would suppress A. litchii infestation, i.e. formation of erinea, on lychee plants under field conditions. Four groups of A. litchii-infested plants were randomly distributed in the field, with each group receiving either Phytoseius intermedius, Amblyseius herbicolus, A. herbicolus supplemented with cattail pollen or no predator. During a three-month period, the released predators, along with others present in the surrounding environment, were allowed to freely walk among all plants. In each plant, we evaluated the occurrence of phytoseiid species, their abundance, and the dynamics of erinea formation. A total of 2,097 mites, including 13 other phytoseiid species were identified. The most abundant species were Iphiseiodes zuluagai and Euseius ho, rather than the two predator species that were released. A. herbicolus and P. intermedius failed to establish populations in the majority of the plants, regardless of the presence of pollen, suggesting their ineffectiveness in controlling A. litchii infestations. While there was a significant difference in the proportion of erinea among the four treatments, this contrast was not associated with the presence of phytoseiids, suggesting that other factors might have hindered erinea formation on lychee plants. The reasons behind this outcome are further explored and discussed.

[Predatory journals in Orthopedics and Traumatology]. / Revistas depredadoras en Ortopedia y Traumatología.

Predatory journals are distinguished from legitimate journals by their lack of adequate reviews and editorial processes, compromising the quality of published content. These journals do not conduct peer reviews or detect plagiarism, and accept manuscripts without requiring substantial modifications. Their near 100% acceptance rate is driven by profit motives, regardless of the content they publish. While they boast a prestigious editorial board composed of renowned researchers, in most cases, it is a facade aimed at impressing and attracting investigators. Furthermore, these journals lack appropriate ethical practices and are non-transparent in their editorial processes. Predatory journals have impacted multiple disciplines, including Orthopedics and Traumatology, and their presence remains unknown to many researchers, making them unwitting victims. Their strategy involves soliciting articles via email from authors who have published in legitimate journals, promising quick, easy, and inexpensive publication. The implications and negative consequences of predatory journals on the scientific community and researchers are numerous. The purpose of this work is to provide general information about these journals, specifically in the field of Orthopedics and Traumatology, offering guidelines to identify and avoid them, so that authors can make informed decisions when publishing their manuscripts and avoid falling into the hands of predatory journals or publishers.

Las revistas depredadoras se diferencian de las revistas legítimas por su falta de adecuadas revisiones y procesos editoriales, lo que compromete la calidad del contenido publicado. Estas revistas no llevan a cabo revisiones por pares ni realizan acciones que detecten y prevengan el plagio y aceptan manuscritos sin exigir modificaciones sustanciales. Su tasa de aceptación cercana al 100% se debe a su enfoque lucrativo, sin importarles el contenido que publican. Aunque presumen tener un comité editorial compuesto por investigadores destacados, en la mayoría de los casos es una simulación destinada a impresionar y atraer a los investigadores. Además, estas revistas carecen de prácticas éticas adecuadas y no son transparentes en sus procesos editoriales. Las revistas depredadoras han afectado a múltiples disciplinas, incluida la Ortopedia y Traumatología y su presencia es aún desconocida para muchos investigadores, lo que los convierte en víctimas sin saberlo. Su estrategia consiste en solicitar artículos por correo electrónico a autores que han publicado en revistas legítimas, prometiendo una publicación rápida, sencilla y económica. Las implicaciones y consecuencias negativas de las revistas depredadoras en la comunidad científica y los investigadores son numerosas. El propósito de este trabajo es proporcionar información general sobre estas revistas y específicamente en el campo de la Ortopedia y Traumatología, brindando pautas para identificarlas y evitarlas, para que los autores puedan tomar decisiones informadas al publicar sus manuscritos y evitar caer en manos de revistas o editoriales depredadoras.

Are predatory mites effective as biological control agents to suppress Oligonychus ilicis (Acari: Tetranychidae) in blueberry plantings?

Southern red mite, Oligonychus ilicis McGregor (Acari: Tetranychidae), is an important polyphagous spider mite pest that causes economic damage to many ornamentals, coffee, and fruit crops. Blueberry growers in the Southeastern United States, including Florida and Georgia, have experienced severe losses due to outbreaks of O. ilicis. Predatory mites are an important management tool used for controlling spider mites; however, predators have not been studied and successfully evaluated in blueberry systems. Amblyseius swirskii Athias-Henriot, Phytoseiulus persimilis Athias-Henriot, and Neoseiulus californicus (McGregor) (Acari: Phytoseiidae) are among the most economically important arthropod agents used in augmentative biological control worldwide. To evaluate the potential of these 3 commercially available predatory mites for use in blueberry plantings, we conducted experiments under controlled laboratory conditions and in the greenhouse. In preliminary laboratory experiments, P. persimilis and N. californicus significantly reduced the number of O. ilicis motile stages below those found in the untreated control, indicating the potential for these 2 predatory mite species to suppress O. ilicis populations. Amblyseius swirskii did not perform well controlling O. ilicis motiles in the laboratory. Under greenhouse conditions, N. californicus and P. persimilis significantly reduced the number of eggs after 7 days of release and the number of motile stages after 14 days of release. This is the first report of using phytoseiid mites to suppress O. ilicis in blueberry systems in the United States. Further studies on predator behavior, feeding preferences, and acaricide compatibility with predators are required to investigate the possibility of using P. persimilis, and N. californicus as biological control agents of O. ilicis in blueberry systems.

The Gray Zone Between Legitimate and Predatory Open Access Scientific Publishing

ABSTRACT Certain open access publishers based on the article processing charges model have found it highly profitable to operate within a gray zone that encompasses both legitimate and predatory publishing practices. In this context, maximum profits can be obtained by adequate combinations of journal acceptance rates and elevated article processing charges. Considering that the gray zone can be particularly challenging to identify and that it poses risks for authors aiming to establish academic carreers, we believe it is important to provide a comprehensive description of it.

Field evaluation of the efficacy of copper nanoparticles against mites associated with orange trees / Avaliação de campo da eficácia de nanopartículas de cobre contra ácaros associados às laranjeiras

Phytophagous mites are dangerous pests, causing economic losses to the world's crops. Nanotechnology is a promising field for pests and disease management, and enhancement of agricultural productivity. The aim of the study was to evaluation of the effectiveness of copper nanoparticles (CuNP) against all stages of eriophyid mite, the citrus rust mite, Phyllocoptruta oleivora (Ashmead) (Acari: Eriophyidae) and tetranychid mite, the citrus brown mite Eutetranychus orientalis (Klein) (Acari: Tetranychidae), and Tenuipalpid mite, the false spider mite, Brevipalpus obovatus Donnadieu (Acari: Tenuipalpidae). This includes its impacts on predacious mites, Amblyseius swirskii Athias-Henriot and Euseius scutalis (Athias-Henriot) (Acari: Phytoseiidae), on orange trees under field conditions. Five different concentrations of copper nanoparticles (40, 80, 160, 240, and 320 ppm), as well as the control (well water) were examined. The obtained results indicated that the mortality rate of both phytophagous and predacious mites was associated with an increase in the concentrations of copper nanoparticles. Copper nanoparticles were significantly effective in killing P. oleivora, E. orientalis and B. obovatus with minimal effects on A. swirskii and E. scutalis. The mortality percentage was 15.24, 20.32, 46.32, 78.97 and 86.37% for P. oleivora, 6.87, 9.86, 28.91, 56.30 and 77.52% for E. orientalis and 8.38, 23.50, 48.83, 68.80 and 84.08% for B. obovatus while the mortality percentage was 0.00, 0.56, 5.83, 9.91 and 15.19% for A. swirskii and 0.44, 3.96, 6.93, 8.63 and 21.39% for E. scutalis one week after exposure to 40, 80, 160, 240 and 320 ppm of copper nanoparticles, respectively. Moreover, the results showed that copper nanoparticles caused a reduction in the percentage of eggs hatching. The percentages of larvae hatching from eggs were 96.29, 80.00, 64.13, 45.66 and 32.17% for P. oleivora, 97.38, 83.28, 69.41, 48.01 and 35.29 for E. orientalis and 96.60, 76.92, 56.38, 40.55 and 33.28% for B. obovatus one week after exposure to copper nanoparticles at 40, 80, 160, 240 and 320 ppm respectively, compared with the control (well water). According to the results, the use of copper nanoparticles significant effect on reducing the population of phytophagous mites associated with orange trees, with low detrimental effects on predatory mites.

Os ácaros fitófagos são pragas perigosas, causando prejuízos econômicos às lavouras mundiais. A nanotecnologia é um campo promissor para o manejo de pragas e doenças, aumentando a produtividade agrícola. O objetivo do presente estudo foi avaliar a eficácia de nanopartículas de cobre (CuNP) em laranjeiras em condições de campo, contra todos os estágios das seguintes espécies: o ácaro eriofídeo, também chamado de ácaro da falsa ferrugem dos citros, ou Phyllocoptruta oleivora (Ashmead) (Acari: Eriophyidae); o ácaro tetraniquídeo, também chamado de ácaro marrom dos citros, ou Eutetranychus orientalis (Klein) (Acari: Tetranychidae); e o ácaro Tenuipalpidae, também chamado de falso ácaro, ou Brevipalpus obovatus (Donnadieu) (Acari: Tenuipalpidae). Isso inclui seus impactos sobre ácaros predadores, como o Amblyseius swirskii Athias-Henriot e o Euseius scutalis (Athias-Henriot) (Acari: Phytoseiidae). Foram examinadas cinco diferentes concentrações de nanopartículas de cobre (40, 80, 160, 240 e 320 ppm), assim como o controle (água de poço). Os resultados obtidos indicaram que a taxa de mortalidade de ácaros fitófagos e predadores esteve associada ao aumento das concentrações de nanopartículas de cobre. As nanopartículas de cobre foram significativamente eficazes em matar o P. oleivora, o E. orientalis e o B. obovatus, com efeitos mínimos sobre o A. swirskii e o E. scutalis. As porcentagens de mortalidade foram: 15,24, 20,32, 46,32, 78,97 e 86,37% para P. oleivora; 6,87, 9,86, 28,91, 56,30 e 77,52% para E. orientalis; 8,38, 23,50, 48,83, 68,80 e 84,08% para B. obovatus; 0,00, 0,56, 5,83, 9,91 e 15,19% para A. swirskii; e 0,44, 3,96, 6,93, 8,63 e 21,39% para E. scutalis, uma semana após a exposição a 40, 80, 160, 240 e 320 ppm de nanopartículas de cobre, respectivamente. Além disso, os resultados mostraram que as nanopartículas de cobre causaram uma redução na porcentagem de eclosão dos ovos. As porcentagens de larvas eclodindo dos ovos foram: 96,29, 80,00, 64,13, 45,66 e 32,17% para P. oleivora; 97,38, 83,28, 69,41, 48,01 e 35,29 para E. orientalis; e 96,60, 76,92, 56,38, 40,58 e 33,29 para B. obovatus, uma semana após a exposição às nanopartículas de cobre a 40, 80, 160, 240 e 320 ppm, respectivamente, em comparação com o controle (água de poço). De acordo com os resultados, o uso de nanopartículas de cobre teve efeito significativo na redução da população de ácaros fitófagos associados às laranjeiras, com baixo efeito prejudicial aos ácaros predadores.

Intra-ocular Predation of Fluoroquinolone-Resistant Pseudomonas aeruginosa and Serratia marcescens by Predatory Bacteria.

Endogenous endophthalmitis caused by Gram-negative bacteria is an intra-ocular infection that can rapidly progress to irreversible loss of vision. While most endophthalmitis isolates are susceptible to antibiotic therapy, the emergence of resistant bacteria necessitates alternative approaches to combat intraocular bacterial proliferation. In this study the ability of predatory bacteria to limit intraocular growth of Pseudomonas aeruginosa, Serratia marcescens, and Staphylococcus aureus was evaluated in a New Zealand White rabbit endophthalmitis prevention model. Predatory bacteria Bdellovibrio bacteriovorus and Micavibrio aeruginosavorus were able to reduce proliferation of keratitis isolates of P. aeruginosa and S. marcescens. However, it was not able to significantly reduce S. aureus, which is not a productive prey for these predatory bacteria, suggesting that the inhibitory effect on P. aeruginosa requires active predation rather than an antimicrobial immune response. Similarly, UV-inactivated B. bacteriovorus were unable to prevent proliferation of P. aeruginosa. Together, these data suggest in vivo predation of Gram-negative bacteria within the intra-ocular environment.

Revistas depredadoras y secuestradas en cirugía. Qué se debe saber sobre ellas y cómo evitarlas

Las revistas depredadoras (RD), constituyen una gran amenaza para la publicación contemporánea, ya que ofrecen una publicación rápida de acceso abierto a cambio de tarifas sin procedimientos de revisión por pares para científicos jóvenes o inexpertos. Son compañías que priorizan el interés propio a expensas de la academia, caracterizándose por entregar información falsa o engañosa, distorsión de las mejores prácticas editoriales y de publicación, falta de transparencia y uso de tácticas de solicitud de manuscritos indiscriminadas y agresivas. El objetivo de este manuscrito fue generar un documento de estudio sobre las RD y secuestradas; así como de las conferencias depredadoras en cirugía.

Predatory journals (PD) are a major threat to contemporary publishing, as they offer rapid open access publication for fees without peer review procedures for young or inexperienced scientists. Are companies that prioritize self-interest at the expense of academia, characterized by providing false or misleading information, misrepresentation of publishing and editorial best practices, lack of transparency, and use of indiscriminate and aggressive manuscript solicitation tactics. The aim of this manuscript was to generate a study document regarding the PD, hijacked journals and predatory conferences in surgery.

Predatory behavior under monocular and binocular conditions in the semiterrestrial crab Neohelice granulata.

Introduction: Neohelice granulata crabs live in mudflats where they prey upon smaller crabs. Predatory behavior can be elicited in the laboratory by a dummy moving at ground level in an artificial arena. Previous research found that crabs do not use apparent dummy size nor its retinal speed as a criterion to initiate attacks, relying instead on actual size and distance to the target. To estimate the distance to an object on the ground, Neohelice could rely on angular declination below the horizon or, since they are broad-fronted with eye stalks far apart, on stereopsis. Unlike other animals, binocular vision does not widen the visual field of crabs since they already cover 360° monocularly. There exist nonetheless areas of the eye with increased resolution. Methods: We tested how predatory responses towards the dummy changed when animals' vision was monocular (one eye occluded by opaque black paint) compared to binocular. Results: Even though monocular crabs could still perform predatory behaviors, we found a steep reduction in the number of attacks. Predatory performance defined by the probability of completing the attacks and the success rate (the probability of making contact with the dummy once the attack was initiated) was impaired too. Monocular crabs tended to use frontal, ballistic jumps (lunge behavior) less, and the accuracy of those attacks was reduced. Monocular crabs used prey interception (moving toward the dummy while it approached the crab) more frequently, favoring attacks when the dummy was ipsilateral to the viewing eye. Instead, binocular crabs' responses were balanced in the right and left hemifields. Both groups mainly approached the dummy using the lateral field of view, securing speed of response. Conclusion: Although two eyes are not strictly necessary for eliciting predatory responses, binocularity is associated with more frequent and precise attacks.

Revisión de pares, preprints y revistas depredadoras. Ética editorial versus publicidad aplicada a la ciencia médica / Peer review, preprints and predatory journals. Publication ethics versus publicity applied to medical science

Abstract The publication of medical articles has become increasingly complex, linked to multiple factors. It poses difficult problems for both authors and journals themselves. This Editorial addresses current and controversial issues: peer review, preprints as a new way of disseminating knowledge, the growing number of publications without peer review and its variants, and the risks of predatory publications. The article proposes future guidelines as an editorial policy of MEDICINA. The controversy continues, and surely the passage of time will place our proposal in a changing scientific world like knowledge itself.

To escape or to pursue: opposite decision making concerning a single moving object is influenced by starvation and sex.

Decision-making processes in the context of prey-predator interactions are studied from the side of the prey or the predator. Thus, prey capture and escape behaviours are researched separately, using different stimuli in different species. The crab Neohelice preys upon individuals of its own species; hence, it behaves as prey and as predator. These two innate opposite behaviours can be elicited by the same object moving on the ground. Here, we studied how the decision to perform avoidance, predatory or freezing responses to a moving dummy depends on sex and starvation level. In the first experiment, we assessed the probability of each response type in unfed crabs for 22 days. Males showed a higher predatory response probability than females. When starvation increased, the predatory response increased, while avoidance and freezing declined, but this only occurred in males. In the second experiment, we compared regularly fed and unfed males for 17 days. While fed crabs did not change their behaviour throughout the experiment, unfed crabs significantly intensified their predatory responses, displayed different exploratory activities and pursued earlier than fed crabs. Our results show the unusual situation of an animal that, to deal with a single stimulus, has to choose between opposite innate behaviours. This is a value-based decision as it is affected by factors other than the stimulus itself.

Mites associated with budgerigars Melopsittacus undulatus (Psittaciformes: Psittacidae) and the first report of Ornithonyssus bursa (Mesostigmata: Macronyssidae) in Mexico.

Background: Hematophagous mites affect numerous bird species, causing severe injuries to the budgerigars. Some species can cause dermatitis in humans. Aims: The purpose was to morphologically identify the mites related to budgerigars (Melopsittacus undulatus) and their nests in Yucatan, Mexico. Methods: In May 2022, a private budgerigar hatchery was visited and mites were collected from the bodies of the birds and their nests. The morphological traits of the mites were confirmed by scanning electron microscopy. Results: Four of 30 birds showed severe clinical signs of mite infestation. The Budgerigars revealed lesions in the cere, nostrils, eyelids, beak, and paws. The bird's skin showed signs of dryness and beige coloring. The birds with severe damage also presented anorexia and had deformed paws and beaks. The parasitosis was caused by the "burrowing mites," Knemidocoptes pilae. The burrowing mites and the Grallacheles bakeri were recovered and identified from paw scabs. To eliminate mites, a topical application of Ivermectin was administered to the necks of the birds. The dose was a single, which has a residuality of 21 days. Two drops (0.115 mg/ml) of ivermectin were applied to each bird. A gradual reduction in crusted lesions due to mite mortality was noted. The "tropical fowl mite" Ornithonyssus bursa was identified in the nests, which represents the first record in Mexico. Conclusions: Three species of mites were discovered in a single budgerigar hatchery. This emphasizes the importance of deworming birds and keeping a clean environment in their cages to reduce the potential for parasitic mite infestation.

Heteropteran Bugs Assemblage Associated to Organic Tomato Farms: Knowledge for Pest Management.

The suborder Heteroptera (Hemiptera) includes zoophagous and zoophytophagous species which conform diverse natural enemies' systems with potential to control several horticultural pests. In this study, we report the assemblage structure of heteropteran bugs species inhabiting open-field and greenhouse organic tomato crops and one common adjacent non-crop solanaceous plant, Solanum sisymbriifolium, in North Buenos Aires province, Argentina, aimed to select promissory biocontrol species. Biweekly direct inspection of selected plants was carried out during a 3-year period (2017-2019) to collect hemipteran nymphs and adults. As a result, nine species and morphospecies belonging to Berytidae (zoophytophagous), Lygaeidae (phytophagous), and Miridae (phytophagous and zoophytophagous) were found, with ≥ 75% of species belonging to the latter family. The zoophytophagous mirid Tupiocoris cucurbitaceus (Spinola) was the most frequent and dominant species in all sites studied. Among the phytophagous species, Nysius simulans Stål was mostly present in greenhouse crops. The community found in greenhouse tomato crops was more diverse than that registered in open-field crops. The characterization of the heteropteran complex in organic tomato farms provides basic knowledge necessary to design pest control strategies in the region studied.

Bioactivity of essential oils from Croton grewioides and its major compounds: toxicity to soybean looper Chrysodeixis includens and selectivity to the predatory stink bug Podisus nigrispinus.

Natural biological control is a key factor that ensures the regulation of insect pest populations in agroecosystems. However, the indiscriminate use of pesticides has compromised this environmental service. Thus, the search for environmentally safe pesticides is an increasing requirement for sustainable food production. In this study, we analyzed the toxicity of essential oils from two accessions (CGR112 and CGR126) of Croton grewioides and its major compounds, methyl eugenol and eugenol, on the soybean pest Chrysodeixis includens. In addition, we investigated the sublethal effects of these compounds on the predatory bug Podisus nigrispinus, analyzing its developmental, reproduction and life table parameters. Essential oils and their major compounds were toxic to C. includens and P. nigrispinus. In general, the presence of eugenol made the essential oil more toxic to the pest and selective to the natural enemy. Eugenol was the most toxic compound for 2nd instar larvae of C. includens at LD50, followed by CGR126 essential oil from C. grewioides which was equally toxic at higher doses. The estimated lethal times for essential oils to cause mortality in 50% of the population of C. includens were less than 15 h. There was selectivity of the essential oil of CGR126 accession of C. grewioides at lethal doses above 90%. Although the treatments showed little effect on the development of P. nigrispinus, body mass and reproductive parameters were negatively affected, with the exception of the essential oil of CGR126 accession of C. grewioides. The essential oil of C. grewioides may be a promising active ingredient for the synthesis of new insecticides, which are efficient against C. includens and at the same time are safer for the natural enemy P. nigrispinus.

Fear in urban landscapes: conspecific flock size drives escape decisions in tropical birds.

Human-induced disturbances affect animal behaviours such as anti-predatory responses. Animals in urban environments tend to exhibit a reduced escape response, measured as a shorter flight initiation distance (FID), compared to their rural counterparts. While FID has been evaluated in animals dwelling in contrasting habitats (e.g. urban versus rural), little is known about how this response varies within urban environments, especially in tropical cities. Here, we studied the FID of 15 resident bird species in Bogota, Colombia, at 22 sites grouped into four categories (natural sites, metropolitan parks, zonal parks and residential areas) that differed in landscape features and evaluated which factors affected the escape responses of birds. We showed that birds foraging in larger flocks are more tolerant when being approached but they do not seem to be influenced by other factors such as heterospecific flock size, noise levels, pedestrian density, predator density, natural cover or body length. Also, birds inhabiting residential areas and parks showed a shorter FID compared to birds in natural areas suggesting that they are more tolerant of human-related disturbances compared to their conspecifics that live in natural areas within the city. Our study shows important differences in bird anti-predatory responses within the city and suggests that social strategies (i.e. flocking patterns) may be a mechanism for adapting to human-induced disturbances in urban tropical environments.

Un caso de publicación en revista médica pirata / A case of publication in a predatory medical journal

Las revistas piratas o depredadoras (predatory journals en inglés) son cada vez más frecuentes y sorprenden en su buena fe a investigadores/as que buscan publicar sus manuscritos. Este artículo presenta un caso de descubrimiento y demostración de publicación en una revista pirata y un conjunto de sugerencias para evitar este error, como un aporte a profesionales de ciencias de la salud que realizan actividades de investigación. El resultado de las investigaciones mostró que la revista European Journal of Gynaecological Oncology(EJGO) es una revista pirata: fundada en 1980, solo desde 2020 posee International Standard Serial Number (ISSN) digital: sus primeras editoras, hasta 2020, no trabajaban en el área disciplinar de la revista ni pudieron ser rastreadas en ORCID; su actual editor no responde correos; la dirección postal de la editorial es la misma de una empresa canadiense importadora de juguetes. Hasta 2021 no poseía una plataforma web para el envío del manuscrito sino se enviaba el trabajo a un correo electrónico genérico. A raíz de nuestras denuncias fue suspendida de Scopus (Scimago) y Clarivate (Web of Science). Cuando Clarivate forzó a EJGO a avisar a sus lectores que estaba suspendida, inmediatamente cambió su página web y la empresa editora. En síntesis, se muestra un caso real de publicación en una revista pirata, la detección y comprobación de que dicha revista efectivamente cae en esta categoría y el aporte de conceptos y definiciones para tener en cuenta a fin de evitar caer en este error. (AU)

Predatory journals are becoming more frequent every day and surprise researchers who seek to publish their manuscripts. This article presents a case of discovery and demonstration of publication in a predatory journal and a set of suggestions to avoid this error, in a contribution to the education of health science professionals. The result of the research showed that the European Journal of Gynaecological Oncology (EJGO) is a pirate journal: founded in 1980, it obtainthe digital International Standard Serial Number (ISSN) in 2020; its former editors, until 2020, do not work in the disciplinary area of the journal and could not be tracked in ORCID, the new editor did not respond any mail; the postal address of the publisher is the same as that of a Canadian toy import company. Until 2021, it did not have a web platform for sending the manuscript, but rather the work was sent to a generic email. As a result of our complaints, it was suspended from Scopus (Scimago) and Clarivate (Web of Science).When Clarivate forced EJGO to notify its readers that it was suspended, it immediately changed its website and publisher. In brief, a real case of publication in a predatory journal is shown, the detection and verification that this journal actually falls into this category and contribution of concepts and definitions to avoid falling into this error.

Individual integrity and public morality in scientific publishing.

Science and science reporting are under threat. Knowingly or not, researchers and clinicians are part of this debacle. This is not due so much to the notorious replication crisis, as to our acceptance of lowering common morality for personal gains, including the widespread, deprecable phenomenon of predatory publishing. Rather than fiercefully countering this loathsome practice, academics are accepting, often supporting a masquerade solution: paying several thousand dollars to publish for all their own papers. This new policy will create a disparity across richer and poorer disciplines; will result in concentrating even more in the hands of large, rich, Western institutions, also penalising younger researchers; will kill observational studies and exploratory research; and will make disseminating science depending more on finances than on quality. This article calls for the full awareness of the academic community on the risks of the current situation in scientific publishing.

Isso não se deve tanto à notória crise de replicação, mas à nossa aceitação de rebaixar a moralidade comum para ganhos pessoais, incluindo o fenômeno generalizado e depreciável da publicação predatória. Em vez de combater ferozmente essa prática repugnante, os acadêmicos estão aceitando, muitas vezes até apoiando uma solução de disfarce: pagar vários milhares de dólares para publicar seus próprios artigos. Essa nova política criará uma disparidade entre as disciplinas mais ricas e mais pobres, resultará na concentração ainda maior nas mãos de grandes e ricas instituições ocidentais, penalizando também os pesquisadores mais jovens; matará os estudos observacionais e a pesquisa exploratória e fará com que a divulgação científica dependa mais das finanças do que da qualidade. Este artigo apela à plena consciência da comunidade acadêmica sobre os riscos da situação atual da publicação científica.

Pinching or stinging? Comparing prey capture among scorpions with contrasting morphologies.

Background: Scorpions can use their pincers and/or stingers to subdue and immobilize their prey. A scorpion can thus choose between strategies involving force or venom, or both, depending on what is required to subdue its prey. Scorpions vary greatly in the size and strength of their pincers, and in the efficacy of their venom. Whether this variability is driven by their defensive or prey incapacitation functionis unknown. In this study, we test if scorpion species with different pincer morphologies and venom efficacies use these weapons differently during prey subjugation. To that end, we observed Opisthacanthus elatus and Chactas sp. with large pincers and Centruroides edwardsii and Tityus sp. with slender pincers. Methods: The scorpion pinch force was measured, and behavioral experiments were performed with hard and soft prey (Blaptica dubia and Acheta domesticus). Stinger use, sting frequency and immobilization time were measured. Results: We found that scorpions with large pincers such as O. elatus produce more force and use the stinger less, mostly subjugating prey by crushing them with the pincers. In C. edwardsii and Tityus sp. we found they use their slender and relatively weak pincers for holding the prey, but seem to predominantly use the stinger to subjugate them. On the other hand, Chactas sp. uses both strategies although it has a high pinch force. Conclusions: Our results show that scorpionspecies with massive pincers and high pinch force as O. elatus use the stinger less for prey subjugation than scorpionspecies with slenderpincers.
