Pensoft among the first 27 publishers to share prices & services via the Journal Comparison Service by Plan S

All journals published by Pensoft – each using the publisher’s self-developed ARPHA Platform – provide extensive and transparent information about their costs and services in line with the Plan S principles.

In support of transparency and openness in scholarly publishing and academia, the scientific publisher and technology provider Pensoft joined the Journal Comparison Service (JCS) initiative by cOAlition S, an alliance of national funders and charitable bodies working to increase the volume of free-to-read research.

As a result, all journals published by Pensoft – each using the publisher’s self-developed ARPHA Platform – provide extensive and transparent information about their costs and services in line with the Plan S principles.

The JCS was launched to aid libraries and library consortia – the ones negotiating and participating in Open Access agreements with publishers – by providing them with everything they need to know in order to determine whether the prices charged by a certain journal are fair and corresponding to the quality of the service.

According to cOAlition S, an increasing number of libraries and library consortia from Europe, Africa, North America, and Australia have registered with the JCS over the past year since the launch of the portal in September 2021.

While access to the JCS is only open to librarians, individual researchers may also make use of the data provided by the participating publishers and their journals.

This is possible through an integration with the Journal Checker Tool, where researchers can simply enter the name of the journal of interest, their funder and affiliation (if applicable) to check whether the scholarly outlet complies with the Open Access policy of the author’s funder. A full list of all academic titles that provide data to the JCS is also publicly available. By being on the list means a journal and its publisher do not only support cOAlition S, but they also demonstrate that they stand for openness and transparency in scholarly publishing.

“We are delighted that Pensoft, along with a number of other publishers, have shared their price and service data through the Journal Comparison Service. Not only are such publishers demonstrating their commitment to open business models and cultures but are also helping to build understanding and trust within the research community.”
said Robert Kiley, Head of Strategy at cOAlition S.

Oldest Pterodactylus fossil found in Germany

The fossil, just described in a study in the journal Fossil Record, is about one million years older than other Pterodactylus specimens.

Pterosaurs, the flying reptiles of the dinosaur era, originated in the Late Triassic (227 million years ago) and became extinct at the end-Cretaceous extinction event (66 million years ago). With wing spans ranging from 1 to 12 meters, they dominated the world’s skies for more than 160 million years.

The first described and named pterosaur – and namesake of the whole group – is Pterodactylus from the famous Solnhofen Limestone of Bavaria, southern Germany. Originally described in 1784 by the Italian naturalist Cosimo Alessandro Collini, the fossil was considered to be an aquatic animal for 25 years, before Georges Cuvier found out it was a flying reptile belonging to a new, previously unrecognized group.

The oldest specimen of this iconic pterosaur was recently found near Painten, a small town in the southern part of the Franconian Alb in central Bavaria. The fossil, described in a study in the journal Fossil Record, is about one million years older than other Pterodactylus specimens.

The specimen was unearthed in 2014 during excavations in an active limestone quarry. It took more than 120 hours of meticulous mechanical work using pneumatic tools and needles before the researchers could study it. The research team behind the discovery are Felix Augustin, Andreas Matzke, Panagiotis Kampouridis and Josephina Hartung from the University of Tübingen (Germany) and Raimund Albersdörfer from the Dinosaurier Museum Altmühltal (Germany).

“The rocks of the quarry, which yielded the new Pterodactylus specimen, consist of silicified limestone that has been dated to the upper Kimmeridgian stage (around 152 million years ago)”, explains Felix Augustin of the University of Tübingen, who is the lead author of the study. “Previously, Pterodactylus had only been found in younger rocks of southern Germany belonging to the Tithonian stage that follows after the Kimmeridgian”.

The specimen is a complete, well-preserved skeleton of a small-sized individual. “Only a very small portion of the left mandible as well as of the left and right tibia is missing. Otherwise, the skeleton is nearly perfectly preserved with every bone present and in its roughly correct anatomical position”, the researchers write in their study.

With a 5-cm-long skull, the Painten Pterodactylus represents a rare “sub-adult” individual. “Generally, the Pterodactylus specimens are not evenly distributed across the full size range but predominantly fall into distinct size-classes that are separated by marked gaps. The specimen from Painten is a rare representative of the first gap between the small and large sizes,” explains Augustin. “The Painten Pterodactylus was of an intermediate, and rarely found, ontogenetic age at the time of its death, between two consecutive year-classes.”

The Painten quarry has yielded many other “exquisitely preserved fossils”, including ichthyosaurs, turtles, marine and terrestrial crocodile-relatives, and dinosaurs. Many of them, like this new pterosaur specimen, are on display in the new Dinosaurier Museum Altmühltal in Denkendorf (Bavaria, Germany).

Pensoft’s ARPHA Publishing Platform integrates with OA Switchboard to streamline reporting to funders of open research

By the time authors open their inboxes to the message their work is online, a similar notification will have also reached their research funder.

By the time authors – who have acknowledged third-party financial support in their research papers submitted to a journal using the Pensoft-developed publishing platform: ARPHA – open their inboxes to the congratulatory message that their work has just been published and made available to the wide world, a similar notification will have also reached their research funder.

This automated workflow is already in effect at all journals (co-)published by Pensoft and those published under their own imprint on the ARPHA Platform, as a result of the new partnership with the OA Switchboard: a community-driven initiative with the mission to serve as a central information exchange hub between stakeholders about open access publications, while making things simpler for everyone involved.

All the submitting author needs to do to ensure that their research funder receives a notification about the publication is to select the supporting agency or the scientific project (e.g. a project supported by Horizon Europe) in the manuscript submission form, using a handy drop-down menu. In either case, the message will be sent to the funding body as soon as the paper is published in the respective journal.

“At Pensoft, we are delighted to announce our integration with the OA Switchboard, as this workflow is yet another excellent practice in scholarly publishing that supports transparency in research. Needless to say, funding and financing are cornerstones in scientific work and scholarship, so it is equally important to ensure funding bodies are provided with full, prompt and convenient reports about their own input.”
comments Prof Lyubomir Penev, CEO and founder of Pensoft and ARPHA.

“Research funders are one of the three key stakeholder groups in OA Switchboard and are represented in our founding partners. They seek support in demonstrating the extent and impact of their research funding and delivering on their commitment to OA. It is great to see Pensoft has started their integration with OA Switchboard with a focus on this specific group, fulfilling an important need,”
adds Yvonne Campfens, Executive Director of the OA Switchboard.

30-million-year-old Baltic amber reveals lacewing that looks like mantis

The insect, described as Mantispa? damzenogedanica, helped reveal important insights into the morphology of these fascinating insects and how it changed through history

Guest blog post by Viktor Baranov

Lacewings (Neuroptera) are mostly known for representatives such as green lacewings or antlions, which are distinguished by their appearance – large eyes and four long wings – but also by their predatory larvae, which play an important role as pest control agents in agriculture. But few non-specialists know that some lacewings can look a lot like praying mantises.

Mantis lacewings (Mantispida) are among the most charismatic, though rather poorly known representatives of the true lacewings. They look like small- to medium-sized praying mantises. Mantis lacewing are 5-47 mm long, and all of them have prominent grasping (also called raptorial) legs. This superficial resemblance is due to the convergent evolution of the shape in true mantises and mantis lacewings. Convergent evolution is a process of organisms evolving similar traits, due to their adaptation to the similar conditions – i.e. hummingbirds and sunbirds live on different continents but look very similar due to their similar lifestyle. This type of evolution has led to the similar shape of the grasping legs, which act as a couple of snap traps for unsuspecting prey.

Going back to the Cretaceous, Mantis lacewings have a long geological record. There are plenty of Mesozoic records of them and their relatives, such as thorny lacewings (Rachiberothidae) and beaded lacewings (Berothidae), totalling 105 recorded specimens. Curiously, there is a clear gap in mantis lacewings records from the Cainozoic.

Until recently, no adult mantis lacewings had been recorded from Baltic amber. In a single case, fossil parasitoid larvae of mantis lacewings were found attached to their host, a spider.

This changed last year, when a beautiful specimen of the mantis lacewing, almost 2 cm long, was brought to our attention by a private amber collector and esteemed supporter of palaeoentomology research – Jonas Damzen from Vilnus, Lithuania. The specimen was found at the Yantarny mine in Kaliningrad oblast, Russia.

By analysing the morphology of this beautiful specimen, we found out that it is closely related to the extant genus Mantispa. However, it was impossible to conclusively corroborate its affinity, because important characters such as rear wing venation and genitalia were obscured by so called “verlummung” – a white film, which covers many of the fossils in Baltic amber.

So, to deal with this uncertainty, we designated this specimen as “probable Mantispa” (Mantispa?). In our research article published in the journal Fossil Record, we gave it the name Mantispa? damzenogedanica. The specific epithet is a combination of ‘Damzen’, honouring Jonas Damzen, who found, prepared, and made the specimen available, and ‘gedanicum’, relative to one of the Latin names for Gdańsk, Poland, where the specimen is housed in the Museum of Gdańsk.

Except for being an impressive, large, imposing insect fossil of the mantis lacewing, and the first one in Baltic amber at that, M.? damzenogedanica also present an intriguing question: why are so few mantis lacewings recorded from this fossil deposit, which is among the best-studied in the world?

Baltic amber deposits were formed in the mid-to-late Eocene epoch (38-33.9 MYA) in Northern Europe. Current consensus on the climate of the area at the time stands that it was not dissimilar to the south of the North American eastern seaboard, for example the Carolinas or Florida’s Panhandle: it was warm-temperate. Such climate is in fact perfect for extant mantis lacewings, so it is logical to suggest that unsuitable climate was not the main reason for the rarity of these animals in Baltic amber.

Analysing the diversity of the shape of mantis lacewings, we found a surprising trend – since the Cretaceous, the diversity in the shape of their legs has decreased. While the shape of the raptorial legs in the Cretaceous was characterised by eclectic, amazing diversity, later mantis lacewings have a rather uniform shape of raptorial legs.

We are not sure what may have caused this decrease. We think that drastic biotic changes after the Cretaceous-Paleogene extinction event (the mass extinction that killed the dinosaurs) may have led to the environment becoming less conductive to mantis lacewings, which in turn decreased their diversity. Thus, it is likely that the rarity of mantis lacewings is simply a reflection of the decline in their diversity and abundance after the Cretaceous-Paleogene extinction.

Younger amber deposits (i.e. Dominican amber), and, of course, extant fauna display significant species diversity, but the diversity of shape never recovered after the Cretaceous. This new mantis lacewing from Baltic amber offers us a rare glimpse into a time when, in the world after dinosaurs, lacewings got a little less diverse and charismatic.
