Ticks are ectoparasite vectors of pathogens affecting human and animal health worldwide. Rational integration of different control interventions including plant-derived repellents and acaricides, management of natural predators, and vaccines is required for innovative approaches to reduce the risks associated with ticks and tick-borne diseases. How tick populations are naturally controlled is always a question. Tick interactions with other arthropods including predators evolved from ancient times. In this study, Cretaceous (ca. 100 Mya) Burmese amber inclusions were identified as probably related to Compluriscutula vetulum (Acari: Ixodida: Ixodidae) tick larvae and spider silk. As illustrated in this study, ancient interactions between ticks and spiders may support arthropod predatory behavior as a natural control intervention. Rational integrative management of different tick control interventions including natural predators under a One Health perspective will contribute to effectively and sustainably reducing the risks associated with ticks and tick-borne diseases.

OBJECTIVE: Radiology faculty across various specialties have been reported to receive an average of 20.7 invitations to submit manuscripts to bogus journals and 4.1 invitations to speak at unsuitable events over a two-week span. Radiology trainees also receive a fair number of unsolicited invitations from unknown senders to submit manuscripts and speak at meetings. Trainees can be more vulnerable to predatory invitations due to potential naivety. We aimed to determine the prevalence of these spam invitations received by radiology trainees.
METHODS: The designed survey for evaluating the experience of radiology trainees regarding phishing scams of predatory publications and conferences was sent to radiology residency and neuroradiology fellowship program leadership to redistribute amongst their trainees, and was advertised on social media platforms. The survey was first sent out on September 28, 2023, and was closed two weeks later October 12, 2023. Spearman\'s correlation, univariable and multivariable linear regression analyses were performed.
RESULTS: Our study included 151 respondents who completed the survey. Of the survey respondents, 53 % reported receiving unsolicited emails from predatory publications (mean = 6.76 ± 7.29), and 32 % reported receiving emails from fraudulent conferences (mean = 5.61 ± 5.77). Significant positive correlation was observed between number of unsolicited email invitations with number of PubMed indexed publications, number as corresponding author, number in open access journals and number of abstract presentations.
CONCLUSIONS: Trainees in radiology receive many unsolicited invitations to publish papers as well as to present at meetings that are not accredited. This could lead to wasted time and financial resources for unsuspecting trainees.

The genus Natronospira is represented by a single species of extremely salt-tolerant aerobic alkaliphilic proteolytic bacterium, isolated from hypersaline soda lakes. When cells of Gram-positive cocci were used as a substrate instead of proteins at extremely haloalkaline conditions, two new members of this genus were enriched and isolated in pure culture from the same sites. Strains AB-CW1 and AB-CW4 are obligate aerobic heterotrophic proteolytic bacteria able to feed on both live and dead cells of staphylococci and a range of proteins and peptides. Similar to the type species, N. proteinivora, the isolates are extremely salt-tolerant obligate alkaliphiles. However, N. proteinivora was unable to use bacterial cells as a substrate. Electron microscopy showed direct contact between the prey and predator cells. Functional analysis of the AB-CW1 and AB-CW4 genomes identified two sets of genes coding for extracellular enzymes potentially involved in the predation and proteolysis, respectively. The first set includes several copies of lysozyme-like GH23 peptidoglycan-lyase and murein-specific M23 [Zn]-di-peptidase enabling the cell wall degradation. The second set features multiple copies of secreted serine and metallopeptidases apparently allowing for the strong proteolytic phenotype. Phylogenomic analysis placed the isolates into the genus Natronospira as two novel species members, and furthermore indicated that this genus forms a deep-branching lineage of a new family (Natronospiraceae) and order (Natronospirales) within the class Gammaproteobacteria. On the basis of distinct phenotypic and genomic properties, strain AB-CW1T (JCM 335396 = UQM 41579) is proposed to be classified as Natronospira elongata sp. nov., and AB-CW4T (JCM 335397 = UQM 41580) as Natronospira bacteriovora sp. nov.

This study investigated the perceptions and factors that researchers had about Open Access (OA) publishing, specifically how it affected their decision to publish or not. The Diffusion of Innovation Theory by Rogers served as the study\'s main guide, and 15 research scientists from Ghana\'s Council of Scientific and Industrial Research\'s Crop Research Institute provided qualitative data for the study through semi-structured interviews and the interpretivist research paradigm. Convenience sampling was used to choose the participants, and thematic analysis was used to analyse and present the research results in themes. The study\'s conclusions showed that all of the participants benefited from OA and that they were all aware of its application for disseminating scientific information. High Article Processing Charges (APC) and credibility issues were also mentioned in the study as significant obstacles to using OA for the dissemination of scientific information. The study suggests that in order for scientists to use Open Access (OA) for the sharing of scientific information, they must be given the means to distinguish trustworthy journals from predatory ones.

Over the last few years, unwanted emails daily fill the mailboxes of many scientists. Usually, they ask the recipient to send a paying article to a journal, generally with a deadline of two weeks. Now the time is coming to openly discuss and mention such kinds of demand and to name the journals behind them. The aim of this paper is thus to present, using some selected examples collected during five days (14-19 October, 2021), the dangers of responding to such a request and to specify the names of the journals concerned. Three otorhinolaryngological journals are particularly discussed: Journal of Otology and Rhinology, American Journal of Otolaryngology Head and Neck Surgery, and Global Journal of Otolaryngology. In selecting some pertinent papers, it is easy to demonstrate that these three journals can easily be considered as predatory journals. Certainly, many other predatory, otorhinolaryngological journals exist. Hopefully, this paper will finally open a serious and scientific discussion about these predatory otorhinolaryngological journals, to definitively establish an available and valid list.

Open-access publishing promotes accessibility to scholarly research at no cost to the reader. The emergence of predatory publishers, which exploit the author-pay model by charging substantial publication fees for publication in journals with questionable publishing processes, is on the rise. Authors are solicited through aggressive marketing tactics, though who is targeted is not well described. The purpose of this study was to identify characteristics associated with critical care pharmacists that make them targets of unsolicited invitations to publish. A prospective, observational study of critical care pharmacists was performed. Participants archived emails received by their professional email that were unsolicited invitations to submit their original work for publication in a journal (unsolicited journals). Variables were evaluated to determine which were associated with unsolicited invitations; these were compared to legitimate journals, defined as all PubMed-indexed journals in which the participants were previously published. Twenty-three pharmacist participants were included, all of whom were residency and/or fellowship trained and practicing in an academic medical center. Participants had a median of 7 years of experience since their post-graduate training, 6 years since their last change in professional email address, and 2 years since their first PubMed-indexed publication. From these participants, 136 unsolicited and 59 legitimate journals were included. The average number of invitations increased 1.04 (95% CI, 1.02-1.05) times for every additional PubMed-indexed publication (P < .001). Most unsolicited journals were considered predatory. Legitimate and unsolicited journals differed significantly. The number of previous PubMed-indexed publications strongly correlates with the likelihood of critical care pharmacists receiving unsolicited publication invitations, often from predatory journal.

Corallococcus sp. strain EGB is a Gram-negative myxobacteria isolated from saline soil, and has considerable potential for the biocontrol of phytopathogenic fungi. However, the detailed mechanisms related to development and predatory behavior are unclear. To obtain a comprehensive overview of genetic features, the genome of strain EGB was sequenced, annotated, and compared with 10 other Corallococcus species. The strain EGB genome was assembled as a single circular chromosome of 9.4 Mb with 7916 coding genes. Phylogenomics analysis showed that strain EGB was most closely related to Corallococcus interemptor AB047A, and it was inferred to be a novel species within the Corallococcus genus. Comparative genomic analysis revealed that the pan-genome of Corallococcus genus was large and open. Only a small proportion of genes were specific to strain EGB, and most of them were annotated as hypothetical proteins. Subsequent analyses showed that strain EGB produced abundant extracellular enzymes such as chitinases and β-(1,3)-glucanases, and proteases to degrade the cell-wall components of phytopathogenic fungi. In addition, 35 biosynthetic gene clusters potentially coding for antimicrobial compounds were identified in the strain EGB, and the majority of them were present in the dispensable pan-genome with unexplored metabolites. Other genes related to secretion and regulation were also explored for strain EGB. This study opens new perspectives in the greater understanding of the predatory behavior of strain EGB, and facilitates a potential application in the biocontrol of fungal plant diseases in the future.

The fraudulent behaviour of predatory journals/conferences through E-mail solicitations and author\'s perspective in unknowingly becoming victims of predatory publishing scheme, by being unaware of the fact that the journals in which they are involved are possibly predatory are highlighted here.

The foraging behavior determines the diet size influencing the growth and reproduction of a predator and its prey populations. Amphipods play a key role in various aquatic ecosystems. Gammarus aequicauda is an abundant widespread omnivorous species and the only known amphipod species of hypersaline waters. Its predation can suppress the populations of planktonic and benthic invertebrates. Males of G. aequicauda actively eat chironomid larvae but there is no data on predatory females. Experiments were conducted to study sex-related differences in feeding behavior including during precopulatory mate guarding (PCMG). There were significant sex differences in feeding characteristics. For females, calculations showed that maximum consumption could be 3-4 chironomid larvae per day and for males about 9-10 larvae per day. During PCMG, males did not feed and females fed as efficiently as single females. Males transported females and alone carrying the energetic costs of swimming during PCMG. Less expenditure of energy on swimming means more energy for reproduction for females. This allows more energy-efficient use of food resources and increases the reproductive success of the population. There are currently two alternative views on PCMG among crustaceans. 1. It is a sexual conflict between males and females serving as a male adaptive strategy to achieve a female during strong male competition, while females bear many costs during the long guarding period. 2. There is also the opposite view that pairs get energetic benefits from long PCMG. Obtained data suggest that PCMG is likely to be intersexual cooperation and not intersexual conflict.

A retrospective observational study was conducted to evaluate open-access journals in obstetrics and gynaecology, published between 2011 and 2019. Journals were classified based on their registration in open-access journal directories. Of 176 journals, 47 were not registered. Journals registered in the Directory of Open Access Journals (DOAJ) demonstrated good overall quality, and their journal metrics were significantly higher than those of non-registered journals or journals registered in other directories. The lack of editor names and indexing information on a journal\'s website are the most distinctive features of non-registered journals. Non-registration in an open-access journal directory indicates a lack of transparency and may ultimately indicate that a journal is predatory.
