Leveraging Landsat and Google Earth Engine for long-term chlorophyll-a monitoring: A case study of Lake Balaton's water quality Chlorophyll-a (Chl-a) is one of the critical water quality indicators that shows the eutrophication status of aquatic ecosystems. As the largest lake …

Making a splash again!
We are excited to share some news straight from the world of limnology and algal biomass monitoring. Here is an article on Lake Balaton and an open-source online tool: lihuan.projects.earthengine.app/view/chla-ba...

Frontiers | The impact of epiphytic algae on the foliar traits of Potamogeton perfoliatus

My latest research paper looked into the relationship between a pondweed with its epiphytic algae. These epiphytes hog the light that the pondweed needs for photosynthesis and mess with the way the pondweeds use the light.

So next time you're taking a dip in Lake Balaton, remember you're diving into a whole different kind of culture! :-D

A long-read sequencing approach to high-resolution profiling of bacterioplankton diversity in a shallow freshwater lake - Scientific Reports Scientific Reports - A long-read sequencing approach to high-resolution profiling of bacterioplankton diversity in a shallow freshwater lake

Our new paper has surfaced!
We took a deep dive (👉) into the bustling microbial metropolis of #LakeBalaton and used some fin-tastic technology to uncover its hidden secrets. Turns out, this lake is teeming with many tiny inhabitants!

You can find more details in the paper:

An outflow of a thermal lake (Hévíz). Only invasive species in the stream water.

The results suggest that environmental degradation tends to decrease the average values of the traits studied, but definitely increases the plasticity of these traits. A similar pattern was observed for plant senescence.
What do you think?

These findings may not rock your boat, but ... hey ... it could improve lake management if you think beyond catchments in a form of clustered management for neighbouring lakes.

🔹 Proximity matters: the closer the lakes, the more similar their biological processes, suggesting that regional factors (such as geology, geomorphology and mesoclimate) sometimes play a greater role than hydrological connectivity.

Here are some old trivia that everyone knows, but I manage to quantify:
🔹 Hydrologically connected lakes show synchrony (yeah ... who knew?), although hydrologically disconnected lakes show higher synchrony of phytoplankton phenological events.

Synchrony of algal blooms in neighbouring lakes: connectivity or territoriality - Hydrobiologia The biological synchrony of neighbouring lakes in Central Europe was evaluated by analysing the concurrent time series of algal biomass variables using long-term (1999–2019) satellite (Landsat 7) deri...

In my latest article I sum up investigation on the biological synchrony of neighbouring lakes in western Hungary using some satellite-derived chlorophyll data
