Description

The digitized Lophophorata collection presented was established in 2025 and will continue to be populated by NHMO’s holdings of the Phyla Bryozoa, Brachiopoda and Phoronida. Several of NHMO’s historical collections from the Dannevig expeditions (1950’s), the Fram 2 expedition (early 1898-1902), and the Norwegian North-Atlantic Expedition (1876-1878), first worked on, among others, by the marine biologist Immanuel Vigeland, nephew of the more famous Gustav Vigeland, and the well-known Ole Nordgaard, are available here. Naturally, material from the Oslofjord, starting from the 1910’s, notably collected by Martit and Bengt Christiansen (Drøbakinnsamlingene, 1950’s) are also included. In addition, voucher specimens from global sequencing efforts, (early 2020's) funded by the European Research Council (ERC), spearheaded by researchers from the NHMO (Evolution and Paleobiology, EPA) from more recent collecting efforts are also represented here.Currently this digital collection is biased towards marine Bryozoa (90%), reflecting not just the known extant diversity of lophophorates (there are 6000+ described  species of living bryozoan but only 400+ species of living brachiopods), but also the research interest of NHMO, in part supported by Artsdatabanken (project NorDigBryo, 2023-2025). There are also freshwater Bryozoa from across Norway collected by Jan Økland. About 60% of this collection is preserved in ethanol, while the rest are dried specimens, some on microscopy slides, as many of these animals are small.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 4,196 records.

6 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Geographic Coverage

More than a third of this collection is from Norway, including collections from the Oslofjord, North Sea, Barents Sea, Norwegian Sea and Skagerrak. However, there is also fair representation from several global regionals including New Zealand /Australia, Antarctica and Canada.

Bounding Coordinates South West [-90, -180], North East [90, 180]

Taxonomic Coverage

The phylum Bryozoa is represented by more than 100 families, the better represented ones being cheilostome families Calloporidae, Candidae, Bugulidae and Smittinidae, and the phylactolamate family Plumatellidae. The phylum Brachiopoda is represented by nine families, notably Craniidae, Cancellothyrididae and Zeilleriidae. The curret collection lacks Phoronida.
