Bryozoa-workshop at Espegrend | The Invertebrate Collections


February 14th -18th 2022

The Bryozoa are perhaps not essentially the most well-known of animals, so let’s begin with a fast rundown: Bryozoa, also called Polyzoa, Ectoprocta, or moss animals (mosdyr, på norsk) are a phylum of aquatic invertebrates. Bryozoans, along with phoronids and brachiopods, have a particular feeding construction referred to as a lophophore, a “crown” of hole tentacles used for filter feeding, which you’ll be able to see in motion within the video Tine captured:

In Norway we have now 292 species registered, of which 281 are marine (Kunnskapsstatus for artsmangfoldet 2020, pdf right here). It’s estimated that the precise variety of species current is greater. Additional, a number of identified species are thought of “door knocker species” which will set up right here throughout the subsequent 50 years.

Bryozoa largely reside in colonies made up of tiny particular person animals referred to as zooids, which develop in a wide range of shapes, and a few of them present structural habitats for different species. They’re meals for a lot of different animals, particularly nudibranchs, fish, sea urchins, pycnogonids, crustaceans, mites and starfish. Marine bryozoans are sometimes accountable for biofouling on ships’ hulls, on docks and marinas, and on offshore buildings. They’re among the many first colonizers of latest or just lately cleaned buildings, and will hitchhike to new locations with marine site visitors. (Bonus: they’ve an excellent attention-grabbing fossil document, and this can be utilized to inform us extra in regards to the world in the best way again!)

A couple of of the shapes the colonies can develop in. Pictured are 1: Membraniporella nitida 2: Bugula sp. 3: Flustrella hispida 4: Crisia eburnea

They’re one of many focus teams of Hardbunnsfauna: there may be nonetheless quite a bit we have no idea about them!

Planning in a pandemic just isn’t straightforward, and we have now needed to postpone our plans for this gathering a number of occasions. The second week of February we may lastly collect our “Group Bryozoa” right here in Bergen for per week of in-depth research of those fascinating animals.

In complete we have been 11 contributors;
College Museum of Bergen: Endre, Jon, Tom and Katrine,
Pure Historical past Museum in Oslo: Lee Hsiang and Mali,
NTNU College Museum: Torkild, Tine (MSc. pupil) and Tiril (MSc. pupil),
and our two guests from overseas:
from the Institute of Oceanology, Polish Academy of Sciences got here Piotr,
and from the Heriot Watt College (Orkney Campus), Joanne.

The primary focus of the workshop was to get as many samples and species as potential recognized, work although the DNA barcode vouchers from samples submitted prematurely and attain a consensus on which species the doubtful ones have been, to community with our colleagues, and to incorporate the scholars within the work and the workforce. All of it went swimmingly, and a we had a really productive and gratifying week!

We arrange camp on Espegrend Marine Organic station, and mixed lengthy days within the lab learning materials collected all through the mission with shorter journeys out on R/V Hans Brattstrøm.

Right here we collected reside colonies, launched the scholars to varied accumulating strategies, and let everybody catch some recent fjord air.

Tine is doing her grasp thesis on the species distribution of Bryozoa in shallow water alongside the Norwegian coast.

In the course of the workshop she acquired the possibility to have among the tough species identifications verified by the consultants,  and she or he ready a plate of 95 tissue samples that can be DNA barcoded although NorBOL.

We additionally had Tiril with us, who’s simply beginning out on what is going to turn out to be a thesis on ascidians (sea squirts), most probably with a give attention to species within the genus Botryllus and Botrylloides. 

She labored along with Tom, getting acquainted with the literature and the strategies used for engaged on the group. Like Tine, she can be utilizing a mixture of conventional morphology primarily based strategies and genetic knowledge.

 

A couple of impressions from the week

Going ahead we’ll first ship the plate of tissue samples to CCDB to be sequenced, fingers crossed for good outcomes! In the course of the week, *so many* samples have been recognized, so we will definitely be getting ready extra plates in the course of the spring. All of the recognized samples can be included into the scientific collections of the museum.

Thanks a lot to all of the contributors for his or her efforts!
