karstein.harsaker@ntnu.no (Karstein Hårsaker) — Tue, 14 Jul 2026 12:04:14 +0000

The bird collection at the NTNU University Museum goes back to approximately 1800. It consists mainly of objects from the norwegian mainland, but also has a small historic collection of birds collected between 1860 and 1910 from all over the world (app. 450 objects). This historic collection includes many species which today are endangered, threatened or distinct. The collection consists mainly of mounted objects, but there are also some skeletons, skulls and objects preserved on ethanol. From the latest years there are also preserved tissue samples of almost all new objects. These samples are stored at -80 degrees C. The geographic coverage of the objects in this collection is mainly Norwegian mainland. Within Norway mainland the majority of objects collected origins from central Norway.

Fish collection NTNU University Museum - Version 1.702

marc.daverdin@ntnu.no (Marc Daverdin) — Tue, 14 Jul 2026 12:03:23 +0000

The collection of fish at the NTNU University Museum dates back to the 1860's. The collection contains both freshwater and marine fish. Almost all of the objects are preserved on ethanol. The marine part of the collection is small and dates back to when there were research on marine fish at the museum, corresponding with when exploration and mapping of marine environments in central Norway started, initially the Trondheimsfjord, but later also coastal areas outside the fjord. The freshwater part of the collection is larger and dates mainly from late 1960's and up to today. This part of the collection contains mainly of anadromous salmonid species (Salmo salar and Salmo trutta, 65 % of the total fish collection). This is mainly due to the museum being involved in numerous projects investigating the effects of Norwegian freshwater systems being used for hydropower production. Todays collection covers most of the species found in the coastal areas and freshwater systems of central Norway. It contains a total of 248 species. The geographic coverage of the objects in this collection is mainly Norwegian mainland, Svalbard and Jan Mayen. Within Norway mainland the majority of objects collected origins from central Norway.

Budalen 2023 Plant Pollinator Survey - Version 1.0

beatrice.m.trascau@ntnu.no (Beatrice Trascau) — Mon, 17 Jun 2024 12:07:04 +0000

This is a documentation of surveys of flowering plants and plant-pollinator interactions done in the Budalen Valley, Norway, as part of a project investigating the impact of different land-use changes on flowering plant diversity and pollination. Three different land-uses were selected: FH (Former Haymaking), EG (Extensive Grazing) and IG (Intensive Grazing). Within each land-use, 3 sites (50m by 25m) were established. Within each site, 5 transects were established, each 5m apart from the previous. For the flowering plant surveys, 5 quadrats were established along each transect, each 10m apart. In each quadrat the frequency of flowering plant was recorded. For the pollinator survey, each plant-pollinator interaction observed whilst walking alongside the transects was recorded. Recording time for each transect was approximately 5 minutes and 30 seconds.

Marine invertebrate collection NTNU University Museum - Version 1.1781

anders.finstad@ntnu.no (Anders Gravbrøt Finstad) — Mon, 13 May 2024 14:58:27 +0000

The marine invertebrate collections at the NTNU University Museum goes back to the activities initiated by Bishop Johan Ernst Gunnerus in the 1760's (Bakken et al. 2011). Only a handful specimens in the collection date back to this period. From around 1870 an exploration and mapping of marine environments in central Norway started, initially the Trondheimsfjord, but later also coastal areas outside the fjord. Sampling activities contributing preserved specimens have been at irregular intervals since the 1870s, and impact in number of objects and taxa represented has mainly been a result of several large projects. Apart from larger sampling programmes, small and single collecting activities has taken place over the period since the start. The collection holds about 120,000 records of most has been digitised. The geographic span of the records are mainly Norwegian waters. Within Norwegian waters a majority origins in the central part of Norway, including the 600 m deep Trondheimsfjord, and the costal areas outside the fjord. In addition there are samples from along the Norwegian coast, primarily north of the Trondheimsfjord, also representing the deep-sea areas in the Norwegian Sea, and from Svalbard. Samples from international marine environments are mainly from neighbouring Nordic countries. But also a number of samples from the Tristan da Cunha archipelago in the South Atlantic, resulting from the Norwegian Tristan da Cunha Expedition 1937-38. All animal phyla with known representing high number of taxa world-wide are represented, but it is obvious from the holdings that some groups are overrepresented compared to others. This reflects the taxonomic expertise among the staff since Vilhelm Storm started exploring the Trondheimsfjord in the1870s (Mork & Sneli 2011). Norwegian waters have been important for describing new species in the early days of natural history explorations, thus representing type localities for a range of marine species described from the 18th century onwards (Oug et al. 2014). The collections at NTNU University Museum holds several type specimens, including from Tristan da Cunha, which has been described in detail (Bakken 1999).

Terrestrial and limnic invertebrates systematic collection, NTNU University Museum - Version 1.1383

anders.finstad@ntnu.no (Anders Gravbrøt Finstad) — Wed, 13 Mar 2024 15:28:26 +0000

The terrestrial and liminic invertebrates systematic collection at the NTNU University Museum dates back to activities initiated by Bishop Johan Ernst Gunnerus in the 1760's and objects from Bjarne Lysholm’s collection of Coleoptera from around 1880-1939. The bulk of the collection dates from the 1960's and up to today and includes the Lepidoptera collection of Carl Fredrik Lühr and Runar Krogen, the Coleoptera collections of Karl Erik Zachariassen and Dagfinn Refseth. A recent acquisition of approximately 160 000 identified specimens came from Frode Ødegaard’s collection previously hosted at the Norwegian Institute for Nature Research. Today's collection covers most of the major groups of invertebrates with Lepidoptera, Coleoptera, Diptera and Hymenoptera as the largest parts of the collections (approximately 40 %, 20 %, 10 % and 7 % respectively in 2017). Some groups are overrepresented compared to others. This reflects the taxonomic expertise among the staff since the first regular employee in the 1840's and donations of private collections. The collection includes objects from all other continents except the Antarctica. Examples from other parts of the world are chironomids from America, Africa, Europe and Asia, a historic circumpolar collection of Coleoptera. Coleoptera from Central America, Australia, southern Europe, Africa and Papua New Guinea. There are also Lepidoptera from Malawi and terrestrial molluscs from Madeira, Cuba and some other countries.

PIKE – Distribution, extinctions and introductions of freshwater fish in Sweden - Version 1.2

anders.finstad@ntnu.no (Anders Gravbrøt Finstad) — Tue, 20 Aug 2019 12:38:57 +0000

The PIKE database are assembled by Göran Englund and co-workers at the Department of Ecology and Environmental Science at Umeå University. It contains information on presence of fish species, as well as introductions of new species, extinctions and rotenone treatments. Most data has been collected by governmental agencies and individuals who have shared their knowledge and data sets. The information derives from field surveys, interviews and inquires. A few hundred lakes have been surveyed within the project to obtain complementary data. Most of the occurrence data have been collected in the period 1890-2012. PIKE also includes information on water chemistry, lake depth, lake area,and much more. Most of the lakes are found in Sweden, but Norway and Finland are also represented.
