Springs ecosystems as refuge areas of diatom biodiversity

Julia Sulkowska talks about the ecological importance of springs, the detrimental impact of human activities on these ecosystems, and the role of bryophytes in providing microhabitats for various species of diatoms.

Diatom of the Month recap

What is new in Diatom of the Month? Hirak Parikh let's us know and asks for posts!

Diatom of the Month – October 23: Palaeoenvironmental reconstruction of a medieval embankment at the lost harbour of Mude (Zeeland, the Netherlands) based on palynology and diatom analysis

Coralie won the best student presentation prize at the AdlaF meeting in 2023. She shares her findings in this post, reviving the Diatom of the Month feature!

Diatom of the Month December 2021 – A quintessential benthic diatom: celebrating 20 years of Seminavis robusta

Biofilms are photosynthetically efficient and provide ecosystem services such as erosion resistance and nutrient cycling. Marine biofilms are often dominated by species-rich benthic diatoms.

Diatom of the Month November 2021 – The diatoms, my friend, are blowin’ in the wind

Why do these particular diatoms live in this place? What role do these species play as part of the ecosystem?

Diatom of the Month October 2021 – Better Together: Rhopalodiaceae team up with nitrogen-fixing bacteria to survive in freshwaters with low nutrients

Nitrogen is required for all living organisms to build proteins and nucleic acids (such as DNA and RNA). However, while nitrogen in its gaseous form makes up approximately 78% of […]

Diatom of the Month September 2021 – Not every diatom acts the same: a bedtime story

I study the diversity of benthic diatoms, with a particular interest in the functional traits of species, such as size, mobility and nitrogen-fixing abilities, because they affect the way that […]

Diatom of the Month August 2021 – Announcing an online workshop with the DOM community

The Diatom of the Month series of posts project has been running every month without interruption since 2015. DOM December 2019 made an extensive review of the first 4 years […]

Diatoms make the world happy: educational outreach using diatom-based activities in the classroom

Websites are a very useful tool for anyone seeking information. However, people who are unaware of diatoms or uninterested in them will not google for diatoms. To inform such people […]

Towards biomonitoring 2.0: Comments on the applicability of diatom DNA metabarcoding in Mediterranean rivers

The difficulties in identifying diatoms based on their morphology have led to the pursuit of new methods that might make diatomists’ lives much easier. One of these methods is DNA […]

Gomphonema clevei, oxygen and Lake Tanganyika, Africa

If anything is well known about Lake Tanganyika, it is its enormous volume, length, and depth. Yet, much less is known about the lake’s ecological history and the potential of […]

Invisible to the naked eye but unique for Neotropical biodiversity

In this Diatom of the Month post we bring the topic of how organisms that are invisible to the naked eye contribute to regional biodiversity. In a recent open-access paper […]

Exploring new territories: sampling phytobenthos in large rivers

Freshwater phytobenthos comprises the algae that live on or are attached to surfaces of, for example rocks, macrophytes (vascular water plants) or sediment/sand grains of rivers and lakes (Figure 1). […]
