Abstract: Northern small mammal populations are renowned for their multi-annual population cycles. Population cycles are multi-faceted and have extensive impacts on the rest of the ecosystem. In 2011, we started a student-based research activity to monitor the variation of small rodent density along an elevation gradient following the Birkebeiner Road, in southeast Norway. Fieldwork was conducted by staff and students at the University campus Evenstad, Inland Norway University of Applied Sciences, which has a long history of researching cyclic population dynamics. The faculty has a strong focus on engaging students in all parts of the research activities, including data collection. Small rodents were monitored using a set of snap trap stations. Trapped animals were measured (e.g. body mass, body length, sex) and dissected to assess their reproductive status. We also characterised the vegetation at trapping sites.We provide a dataset of small rodent observations that show fluctuating population dynamics across an elevation gradient (300 m to 1,100 m a.s.l) and in contrasting habitats. This dataset encompasses three peaks of the typical 3-4-year vole population cycles; the number of small rodents and shrews captured show synchrony and peaked in years 2014, 2017 and 2021. The bank vole Myodes glareolus was by far (87%) the most common species trapped, but also other species were observed (including shrews). We provide digital data collection forms and highlight the importance of long-term data collection.

Plant occurrences on the Rybachy and the Sredny Peninsulas, Murmansk Region, Russia: a dataset https://bdj.pensoft.net/article/77094/ Biodiversity Data Journal 10: e77094

DOI: 10.3897/BDJ.10.e77094

Authors: Ksenia Popova, Anna Razumovskaya

Abstract: The Rybachy and the Sredny Peninsulas are the northernmost part of Murmansk Region in the European part of Russia. While the most part of the Region is covered by boreal forest, the Peninsulas are covered by tundra. The vegetation and flora of Murmansk Region are well studied at present. The Peninsulas were first studied in 1829 by a Finnish botanist Jacob Fellman. The most comprehensive research was conducted in the late 19th - early 20th century. Nevertheless, the species composition of the Peninsulas' flora has changed significantly over the past 100 years due to land use and climate change. The aim of this dataset is to make the data on species occurrences for this territory digitally available via GBIF. To date, more or less complete digital floristic data were provided only by the project for digitising the book "Flora of Murmansk Region" (1953–1966).The present dataset is a part of the project studying the vegetation of the territory. We recorded the information about species frequency and distribution using the relevé method.We present a dataset based on 991 relevés from all vegetation types, which includes 16,289 records of georeferenced plant occurrences that belong to 568 species. There are 23 species of lichens (Ascomycota), 142 species of mosses (Bryophyta), three species of liverworts (Marchantiophyta) and 400 species of vascular plants (Tracheophyta) in the present dataset. The taxonomic diversity and unevenness result from the vegetation sampling. The data were collected in 2008, 2009, 2011, 2014 and 2015. The dataset cannot be considered as a complete vegetation database or a flora checklist, but it contains the occurrences and frequencies of the species from all the vegetation types.

An update to the distribution of invasive Ctenolepisma longicaudatum Escherich in northern Europe, with an overview of other records of Estonian synanthropic bristletails (Insecta: Zygentoma) https://bdj.pensoft.net/article/61848/ Biodiversity Data Journal 9: e61848

DOI: 10.3897/BDJ.9.e61848

Authors: Kaarel Sammet, Mati Martin, Tõnu Kesküla, Olavi Kurina

Abstract: Previously, two species of Zygentoma have been reported from Estonia, both synanthropically. Ctenolepisma longicaudatum Escherich, 1905 is an invasive species that currently expands its range in Europe, but had no published records from the northern Baltic region.Ctenolepisma longicaudatum was first found in Estonia in 2018. It has currently several established populations in public buildings in Tartu, but has not been found in private households, nor in other places in Estonia. A brief overview of its invasion history in northern Europe is given.

The data of the Swedish Malaise Trap Project, a countrywide inventory of Sweden's insect fauna https://bdj.pensoft.net/article/56286/ Biodiversity Data Journal 8: e56286

DOI: 10.3897/BDJ.8.e56286

Authors: Dave Karlsson, Mattias Forshage, Kevin Holston, Fredrik Ronquist

Abstract: Despite Sweden's strong entomological tradition, large portions of its insect fauna remain poorly known. As part of the Swedish Taxonomy Initiative, launched in 2002 to document all multi-cellular species occurring in the country, the first taxonomically-broad inventory of the country's insect fauna was initiated, the Swedish Malaise Trap Project (SMTP). In total, 73 Malaise traps were deployed at 55 localities representing a wide range of habitats across the country. Most traps were run continuously from 2003 to 2006 or for a substantial part of that time period. The total catch is estimated to contain 20 million insects, distributed over 1,919 samples (Karlsson et al. 2020). The samples have been sorted into more than 300 taxonomic units, which are made available for expert identification. Thus far, more than 100 taxonomists have been involved in identifying the sorted material, recording the presence of 4,000 species. One third of these had not been recorded from Sweden before and 700 have tentatively been identified as new to science.Here, we describe the SMTP dataset, published through the Global Biodiversity Information Facility (GBIF). Data on the sorted material are available in the "SMTP Collection Inventory" dataset. It currently includes more than 130,000 records of taxonomically-sorted samples. Data on the identified material are published using the Darwin Core standard for sample-based data. That information is divided up into group-specific datasets, as the sample set processed for each group is different and in most cases non-overlapping. The current data are divided into 79 taxonomic datasets, largely corresponding to taxonomic sorting fractions. The orders Diptera and Hymenoptera together comprise about 90% of the specimens in the material and these orders are mainly sorted to family or subfamily. The remaining insect taxa are mostly sorted to the order level. In total, the 79 datasets currently available comprise around 165,000 specimens, that is, about 1% of the total catch. However, the data are now accumulating rapidly and will be published continuously. The SMTP dataset is unique in that it contains a large proportion of data on previously poorly-known taxa in the Diptera and Hymenoptera.

20th century Betula pubescens subsp. czerepanovii tree- and forest lines in Norway https://bdj.pensoft.net/article/22093/ Biodiversity Data Journal 5: e22093

DOI: 10.3897/BDJ.5.e22093

Authors: Anders Bryn, Kerstin Potthoff

Abstract: Georeferenced tree- and forest line data has a wide range of applications and are increasingly used for e.g. monitoring of climate change impacts and range shift modelling. As part of a research project, registrations of previously re-mapped tree- and forest lines have been georeferenced. The data described in this paper contains 100 re-mapped registrations of Betula pubescens subsp. czerepanovii throughout Norway. All of the re-mapped tree- and forest line localities are georeferenced, elevation and aspect are given, elevational and spatial uncertainty are provided, and the re-mapping methods are explained. The published data weremapped for the first time between 1819 and 1963. The same sites were re-mapped between 1928 and 1996, but have until now been missing spatial coordinates. The entries contain 40 x 2 tree lines and 60 x 2 forest lines, most likely presenting the regionally highest registered tree- and forest lines at the given time. The entire material is stored and available for download through the GBIF server.Previously, the entries have been published in journals or reports, partly in Norwegian or German only. Without the provision of the spatial coordinates, the specific locations have been unknown. The material is now available for modelling and monitoring of tree- and forest line range shifts: The recordings are useful for interpretation of climate change impacts on tree- and forest lines, and the locations of re-mapped tree- and forest lines can be implemented in future monitoring projects. Since the recordings most likely provide the highest registered Betula pubescens subsp. czerepanovii locations within their specific regions, they are probably representing the contemporary physiognomic range limits.

Across the Baltic: a new record for an enigmatic black scavenger fly, Zuskamira inexpectata (Pont, 1987) (Sepsidae) in Finland https://bdj.pensoft.net/article/4308/ Biodiversity Data Journal 3: e4308

DOI: 10.3897/BDJ.3.e4308

Authors: Yuchen Ang, Patrick Rohner, Rudolf Meier

Abstract: Specimens of the enigmatic, monotypic European genus Zuskamira Pont, 1987 (Sepsidae) were initially collected only from the lower central Swedish provinces of Darlana, Uppland and Västmanland. However, the same species was subsequently found much more south in Lower-Saxony and Schleswig-Holstein although Germany is overall well sampled for sepsid flies. Here we report a further (longitudinal) range expansion based on new localities in Southern Finland. New localities for Finland and Sweden are here added and we discuss briefly the habitat requirements of the species.

Unveiling of a cryptic Dicranomyia (Idiopyga) from northern Finland using integrative approach (Diptera, Limoniidae) https://bdj.pensoft.net/article/4238/ Biodiversity Data Journal 2: e4238

DOI: 10.3897/BDJ.2.e4238

Authors: Jukka Salmela, Kari Kaunisto, Varpu Vahtera

Abstract: The subgenus Idiopyga Savchenko, 1987 is a northern hemisphere group of short-palped crane flies (Diptera, Limoniidae). In the current article we describe a new species, Dicranomyia (I.) boreobaltica Salmela sp.n., and redescribe the male and female post-abdomen of a closely related species, D. (I.) intricata Alexander. A standard DNA barcoding fragment of 5′ region of the cytochrome c oxidase I (COI) gene of the new species is presented, whilst the K2P minimum distances between the new species and 10 other species of the subgenus were found to range from 5.1 to 15.7 % (mean 11.2 %). Phylogenetic analyses (parsimony and maximum likelihood) based on COI sequences support the identity of the new species and its close relationship with D. (I.) intricata and D. (I.) esbeni (Nielsen). The new species is known from the northern Baltic area of Finland. The new species has been mostly collected from Baltic coastal meadows but an additional relict population is known from a calcareous rich fen that was estimated to have been at sea level circa 600-700 years ago. Dicranomyia (I.) intricata (syn. D. suecica Nielsen) is a Holarctic species, occurring in the north boreal and subarctic vegetation zones in Fennoscandia.

DOI: 10.3897/BDJ.1.e969

Authors: Jukka Salmela, Eino Savolainen

Abstract: The mayfly species Paraleptophlebia werneri has been rediscovered from Finland. The species was classified as RE (regionally extinct) in the most recent national red-list assessment. The new locality is close to the Russian border in NE Lapland, Savukoski. Adult males were collected with a sweep net around a pond. Paraleptophlebia strandii is a rather poorly known but widespread Finnish species. The adults of this species occurred in great numbers in aapamires of central Lapland (Sodankylä). We hypothesize that these leptophlebid species are not dependent on running water but may instead thrive in small lentic water bodies.
