Analysis internship – Carla García Carrancio


On summer season 2021 I had the chance to conduct a analysis go to on the College Museum of Bergen below venture NorHydro. Concretely, I used to be working with the hydrozoan collections, the place I obtained to know first-hand the position performed by the curators and the significance of the collections. I examined a number of specimens and digitalized their related information creating e-vouchers. Having all the knowledge of specimens in a digital format is essential as a result of it permits different researchers to entry the fabric with out having to return to the museum and helps to make the stock extra accessible and organised. I additionally improved my data of hydrozoan variety by figuring out quite a few specimens deposited on the museum. For that, I used some keys for each thecate and athecate hydroids from North—West European waters in addition to the steerage of my MSc supervisor Luis Martell.

The principle distinction between leptothecate and anthoathecate hydroids is the shortage of theca within the latter (the theca is a cup-like construction that protects the polyps), however a few of them will be very tough to determine since anthoathecate hydroids might have theca-like constructions, and the theca of lepthothecate polyps could also be troublesome to see at first sight. Additionally, while you have a look at a pattern, you might discovered a number of hydrozoans rising on the identical substrate all collectively, making identification much more troublesome. One of many traits used to distinguish species is the presence and the form of the reproductive constructions (gonophores), however they aren’t all the time current if the polyps should not reproductive.

Sertularella rugosa (prime row) is undoubtedly certainly one of my favorite hydrozoans. The hydrothecae resemble a bee hive and the colony has a zig-zag look. Nevertheless, it’s simple to confuse it with Sertularella tenella (backside row). Footage credit: Carla García.

Polyps of the household Campanulariidae. This frequent household is characterised by the presence of a bell-shaped theca. Footage credit: Carla García.

Throughout my keep, I additionally had the prospect to go sampling on a analysis boat, which helped me to know higher the procedures and necessities which can be vital to gather hydrozoans. We used a wide-mouthed plankton internet that went up and down at a relentless velocity to keep away from damaging the jellies and different gelatinous organisms from the plankton. After sampling, we took the cod-end to the laboratory. There, the content material of the cod-end was poured on a light-weight desk. Then, we chosen fascinating specimens (together with hydromedusae belonging to genus Euphysa) with huge mouthed pipettes and transferred them to Petri dishes full of contemporary seawater to watch them higher below a microscope.

Towing the plankton-net which went all the way down to 650m to seize some gelatinous organisms. As you possibly can think about, going up and down such an extended distance takes lots of time, however it’s by no means boring with colleagues like Aino Hosia (proper). Image credit: Carla García.

I used to be fortunate sufficient to get samples of Euphysa aurata and Euphysa sp., however they didn’t wish to pose for my picture and stored transferring round. Image credit: Carla García.

We took the chance to gather some shallow-water benthic hydroids simply in entrance of the Marine Station. Image credit score: Carla García.

Final however not least, I labored on the DNA lab, which allowed me to realize expertise in new molecular strategies that I had not used earlier than and to adapt myself to completely different (and really fashionable) amenities.

This expertise has been merely nice for me. I beloved the working setting and the truth that everyone was all the time there to provide me a hand. I’ve discovered rather a lot and I’m taking with me many associates that I hope to satisfy once more after I come again to Bergen.
