Plankton and art

Those who have seen a plankton sample cannot deny its inherent beauty. From the perfect symmetry of diatoms to the complexity of some radiolarians, we can find an infinite range of shapes and colors that have been a source of inspiration for many artists, ancient and modern. Perhaps we find the maximum expression of the representationContinue reading “Plankton and art”

Microplankton sample, 11/20/2022

I leave you with a selection of pictures from the last plankton sample (2 Km offshore Barcelona, 5 meters depth, November 20, 2022). You can find the movies here: https://www.youtube.com/watch?v=P0KFxcoq_9A for a summary of the relevant species https://www.youtube.com/watch?v=eYfxSVCLrC4 for Acantharia https://www.youtube.com/watch?v=6dNyRKlIk4g for a beautiful Amoeba https://www.youtube.com/watch?v=hRdBe37iO50 for Ceratium spp.

A brief history of plankton discovery

In this post, I will give you a few glimpses of how were the early plankton-human interactions and how we managed to study these creatures. As you will see, there was already evidence from ancient Greece that there were strange beings, including plankton organisms, that did not fit into any known classification. However,perhaps the greatest work wasContinue reading “A brief history of plankton discovery”

Marine Zooplankton Ecology Group Youtube Channel

In the following link, you will find our Zooplankton Ecology Group Youtube Channel. It has many videos of the different organisms we found in our samples, including metazoans and protozoans. You also will find a video on how to make your home-made plankton net. I leave you a few links to the newest and theContinue reading “Marine Zooplankton Ecology Group Youtube Channel”

The ciliate that met a diatom: a case of symbiosis in plankton 

Sometimes, very different organisms get together and form a successful consortium. Lichens, for instance are a symbiotic consortium between and algae and a fungus. In the plankton we have similar relationships. For instance, a ciliate and an alga, once in a while stop being grazer and prey and work together for a better success. ThisContinue reading The ciliate that met a diatom: a case of symbiosis in plankton 

The role of bacteria and algae in the balance of life in the sea (and on land)

Is it true that half of the oxygen we breathe is produced in the sea? The cycle of life inevitably involves creation and destruction. Organisms are born, grow, reproduce (with some luck), and die. In nature, death means an increase in the survival probabilities of someone else. Plankton are no exception to these basic rulesContinue reading The role of bacteria and algae in the balance of life in the sea (and on land)

Today we will sample plankton

Those of you who follow my posts will know that plankton comprise many organisms of different sizes, from viruses about 0.00001 mm to large jellyfish up to a meter in length. It is logical, then, to think that there should be different systems for sampling plankton according to the size of the group of interest.Continue reading Today we will sample plankton
