Danish gall midge (Cecidomyiidae) records
The database comprises occurence and host records of gall midges (Cecidomyiidae, subfam. Cecisomiinae) in Denmark. Its backbone is the catalogue by Skuhravá, Skuhravý and Jørgensen (2006; Entomologiske Meddelelser), which again was based on Marcela Skuhravá's revision of the gall midge collections in the Zoological Museum of the University of Copenhagen, on published records and on own observations made by the authors. The database has been updated with published and unplished records made later than 2006 by knowledgeable cecidologists.

Danish Tingidae - Data for study on occurrence, temporal trends and potential species
This dataset contains the data foundation for the Master Thesis by Kimmie Møenbo Jensen 2017: The Danish Lace-bugs (family Tingidae) and Piesmatidae - Occurrence, temporal trends and potential species. Thesis abstract: Tingidae and Piesmatidae are small families of Heteropterans with a body length varying between 1.5-5 mm. A total of 27 species of Tingidae and 4 species of Piesmatidae are belonging to the Danish fauna, and both families are recognised by lace-like networks of cells, which is especially expressed in species of Tingidae. The species in these families are all host specific phytophagous and can in some cases act as pests. Changes have developed in these families since the first identification key of Danish Tingidae and Piesmatidae from 1912. Furthermore, the occurrence of the Danish species of these families have never been investigated. Thereby the aim of this project is to examine changes within these families through construction of an updated identification key, species descriptions and creation of occurrence maps. Moreover, the georeferencing information will be provided to the Global Biodiversity Information Facility to enrich their database information. In addition this work will describe the potential species for Denmark. All of above goals have been reached through registration and observation of 3528 adult specimens that primarily are from the collections at the Natural History Museum of Denmark and at the Natural History Museum of Aarhus. Observation of the morphology has solely been based on outer characteristics as these are sufficient for correct identification of these families. In addition to own observations the key builds upon comparison of characteristics from other identification keys. GPS-coordinates and a buffer zone have been found for all the specimens so that useful occurrence maps could be made for the distinct species in Denmark. Three new species have been registered within the last two years. These species includes Dictyla humuli, Stephanitis takeyai and Tingis crispata. Furthermore, the potential Danish species Physatocheila smreczynskii may have been discovered in Denmark, but because of similarities with Physatocheila costata it is questionable whether it can be included in the Danish fauna or not. Moreover, it has been discovered that Parapiesma variabile is not a Danish species as previously assumed. Parts of this dataset are now (since March 2022) also accesible through the dynamic datasets published by the Natural History Museum of Denmark (Copenhagen) via the following link: - NHMD Entomology: https://doi.org/10.15468/nnobcm

Out of Sight out of Mind - Camera Traps to uncover the small mammal community of Denmark
Out of Sight out of mind – camera traps to uncover the small mammal community of Denmark reveals the data from an extensive camera trap study. The study aimed at testing a novel, non-invasive, low-cost method of monitoring small mammals. During 2021-2024 a total of 202 camera traps were deployed in 13 different study areas throughout Denmark. The study used novel camera trapping techniques specifically designed for capturing small mammals (< 2 kg). Cameras were placed inside boxes that were modified from the original Mostela camera trap box designed by Dutch researchers (Mos & Hofmeester 2020). A cut-through PWC drainpipe functions as a tracking tunnel allowing the animals to enter the box and be captured by the camera. All camera traps used were Cuddeback G-5048, using a xenon flash and set to take photos as fast as possible when triggered and re-triggered. Cameras were set to continuously sample throughout the deployment period. The resultant dataset consists of more and 150000 photos annotated to species level. Annotation was done manually in the open-access software Wild.ID v.1.0.2 (San Diego Supercomputer Center & Wildlife Insights, 2019). The dataset presented here has been cleaned of blanks and photos taken during setup and pickup of cameras.

Insektmobilen - National citizen science and DNA metabarcoding survey of flying insects in June 2018 and 2019
The Insectmobile (Insektmobilen) is a research project at the National History Museum of Denmark, University of Copenhagen, with the goal to investigate the diversity of flying insects in Denmark. In the summer of 2018, 2019 and 2020 almost 400 volunteers collected flying insects using large custom made insect nets mounted on the roof of their cars. The bulk insect samples were processed with a non-destructive DNA extraction DNA metabarcoding protocol (dx.doi.org/10.17504/protocols.io.bmunk6ve) and sequences were assigned taxonomy by importing the fasta file into GBIF's sequence ID tool (https://www.gbif.org/tools/sequence-id). The sequences were queried against a 99% clustered version of the BOLD Public Database v2024-01-06 public data (COI-5P sequences). The dataset contains unidentified sequences and potential errors and contaminants. For example, even though the primers used were developed as universal primers targeting freshwater insects, you will find other phyla, classes etc. We share these sequences and associated data for the data to be as open as possible, but please do reannotate sequences and filter the data for your specific needs prior to using the data for analysis. Please be aware that the samples may contain gut content of sampled insects and eDNA. Sequence identification certainty is captured in the identificationRemarks field. The bit score is the required size of a sequence database in which the current match could be found just by chance. The bit score is a log2 scaled and normalized raw score. Each increase by one doubles the required database size (2bit-score). The expect value is a parameter that describes the number of hits one can "expect" to see by chance when searching a database of a particular size. It decreases exponentially as the score of the match increases. Hence, a low expect value is better. How much of the query(input) sequence aligns with the match in the the reference database, in percent. Badges representing different identity thresholds (match types); Blast exact match = identity >= 99% and queryCoverage >= 80%. This is within the threshold of the OTU, Blast ambiguous match = identity >= 99% and queryCoverage >= 80%, but there is at least one more match with similar identity, Blast close match = identity < 99% but > 90% and queryCoverage >= 80%. It is something close to the OTU, maybe the same genus, Blast weak match = there is a match, but with identity < 90% or/and queryCoverage < 80%. Depending on the quality of the sequence, bit score, identity and expect value, a higher taxon could be inferred from this, Blast no match = no match to the reference database.

Atlas Flora Danica maps the wild Danish flora. Data collection took place from 1992 through 2012, and the voluntary monitoring work was carried out by members of the Danish Botanical Society. For this project, Denmark was divided into 2228 squares of 5 × 5 km. In all investigated squares, all plant species were recorded with a precision of 100 m (ca. 5.000 of the more than 1 mio. records have a precision from 150 til 5.000 m). About every other square in each 10 x 10 km square (total of 1330 squares) were surveyed and thereby obtaining good coverage of the whole country. The project gratefully received sponsoring from the Aage V. Jensen Nature Foundation. Atlas Flora Danica's purpose is to: 1) Show the Danish plant species’ current distribution and regional frequency, including decline or spread of species. Causes of these changes are discussed. 2) Examine the current status of red-listed, protected and rare plant species. 3) Publicize the Danish flora and the importance of protecting the plants and their habitats.

Birds fallen at Danish Lighthouses 1883 through 1939
This dataset presents occurrence records and notes of birds extracted from the multiple volumes of “Fuglene ved de danske Fyr 1883-1939” (i.e. “Birds at the Danish Lighthouses 1883-1939”).The dataset was created firstly by digitizing the book volumes "Fuglene ved de danske Fyr" into PDF files, OCR-ing the PDF files and finally extracting relevant data and compiling them in a database file. In the period 1883-1939, there were 45 lighthouses and lightships functioning in Denmark. This dataset contains specific occurrence records and notes on bird species that struck 2 of these, namely Lodbjerg Fyr and Hanstholm Fyr. The dataset covers records from during the nights of bird migration period from the years 1886 through 1939 (there were no occurrence records or notes on Lodbjerg Fyr and Hanstholm Fyr between 1883- 1885 and 1887-1888). A total of 1212 records were generated with 742 records from Lodbjerg Fyr and 470 records from Hanstholm Fyr. A detailed description of the sampling and digitization process may be found at: https://samlinger.snm.ku.dk/digitale-ressourcer/research-files/fyrfaldne-fugle/. The two specific lighthouses Lodbjerg Fyr and Hanstholm Fyr were selected for extraction from the book volumes through a suggestion from the Thy National Park, Denmark (http://nationalparkthy.dk/). They wanted to use these specific occurrence data for an exhibition project. This databasing effort has been co-funded by Thy National Park and DanBIF. Future projects could include to extract data on more lighthouses from these digitized book volumes, all available at https://samlinger.snm.ku.dk/digitale-ressourcer/research-files/fyrfaldne-fugle/. The number of specimens of the fallen birds that were sent by light keepers to the Zoological Museum of Copenhagen was also recorded in this dataset. These birds were carefully preserved and catalogued by collection workers at the museum and the specimens can still be found there today. Observations on weather conditions during nights when birds were observed by light keepers were also included. Data from this dataset were extracted from “Report on Birds in Danmark, 1886” (published by Ornis) and Fuglene ved de danske Fyr volumes (published in Videnskabelige Meddelelser fra den Naturhistoriske Forening i København). Most of the book volumes were compiled by Herluf Winge (1857-1923), a Danish zoologist who studied mammalian dentition. After the early death of his brother, Oluf Winge (1855-1889), who was a leading Danish ornithologist at his time, Herluf helped to compile "Fuglene ved de danske Fyr": Birds at the Danish Lighthouses 1891-1910 and until 1912 he supplemented this with his own bird observations.

Breeding bird monitoring in open habitats in National Park Thy
This dataset contains breeding bird records collected by DOF Nordvestjylland within selected project areas in National Park Thy, Denmark. The collaboration between DOF Nordvestjylland and National Park Thy aims to improve knowledge about the effects of different projects within National Park Thy. These projects may include nature management initiatives as well as assessments of the effects of recreational facilities. The knowledge collected through the project is intended to support the development and improvement of nature management both within and beyond National Park Thy. For species covered by a NOVANA technical guideline, the relevant guideline is used. For other species, the methodology follows “Guidelines for counting breeding birds in Vejlerne” ("Vejledning i optælling af ynglefugle i Vejlerne"). The collaboration began in 2022 and has no defined end date. The dataset is therefore expected to develop into a long-term and continuous dataset. The records are collected by volunteers, whose contribution is essential to the implementation of the project.

This dataset consists of records and regional occupancy values of all native and naturalized taxa of land plants (species, subspecies, forma, and varieties), in some cases vascular plants only, as reported by eleven regional floras, which were compiled – and all except one published – in the period 1857-1881. Each flora mainly reports occurrences recorded by the author, but some floras do report older published and unpublished records from their study area. The regional occupancy is typically rendered on a verbatim, semi-quantitative ordinal scale from very rare to very common, but for rarer taxa given as a number of occurrence sites or one or more named occurrence localities. Analysis of patterns of plant richness change based on the data is found in Finderup Nielsen et al. (2019).

Dataset of Danish Species of the Rove Beetle Genus Philonthus (Staphylinidae)
* It should be noted that this dataset only contains specimen NOT vouchered in the Natural History Museum of Denmark (NHMD) and Natural History Museum Aarhus (NHMA), as these are published separately through the institution collection management system (Specify). The dataset was made to support the paper, The Philonthus rove beetles (Coleoptera, Staphylinidae) in the online Danish Beetle Bank published in Entomologiske Meddelelser. It contains distribution data of the Danish Philonthus largely based on recorded specimens from the Danish Beetle Catalog and its additions (Hansen, 1996; Hansen et al., 1998; Hansen et al., 1999; Hansen et al., 2000; Pedersen et al., 2001; Jørum et al. 2002; Pedersen & Runge, 2003; Pedersen et al., 2004; Pedersen & Vagtholm-Jensen, 2005; Jørum et al. 2006; Pedersen et al., 2008; Pedersen et al., 2010; Hansen et al., 2012; Hansen & Jørum, 2014; Hansen & Jørum, 2017; Pedersen, Hansen & Hansen, unpublished). The Danish Beetle Catalog registers occurrences in 11 zoogeographic regions based on Enghoff & Nielsen (1977). These include North West Jutland (NWJ), North East Jutland (NEJ), West Jutland (WJ), East Jutland (EJ), South Jutland (SJ), Funen (F), North West Zealand (NWZ), North East Zealand (NEZ), South Zealand (SZ), Lolland, Falster and Møn (LFM), and Bornholm (B). For each region a specimen has been recorded with precise locality and collecting data, these have been georeferenced and included as a GBIF occurrence dataset here. Furthermore, rare species were checked in the two national species databases, the Arter.dk and Naturbasen for additional records that could be verified.
