Šuspa's cacophonic orchestra (Šukas) has 30th anniversary this year! We celebrated it with a concert.

Šuspa gave a lecture on Monday at the Secondary Business School at Husova street on the topic of Papua New Guinea - nature, people, our research and our students.
Fertilization also modifies the community successional trajectory in the long-term. Although fertilization effects seemed to start decreasing in the last years, they still remain significant two decades after the fertilization event.
Fertilization modifies community species composition and functioning. Fertilization is favouring annuals with higher SLA and influencing the interannual response of the community to seasonal drought differently depending on the species functional group and traits.
A new study led by Mercedes Valerio titled Twenty-year effect of sewage-sludge fertilization in a Mediterranean grassland: Impact on species composition, functional groups and interrelation with climate is now published in in PPEES.

Moreover, all Czech botanists now know the pond frequently used and named after Šuspa - Šuspák near České Budějovice.

A conference of the Czech Botanical Society focused on Czech research abroad was held over the weekend. Šuspa and Lucka gave nice talks about their research in Papua New Guinea. Šuspa was elected an honorary member of the society. Congratulation!

Last week, we established a new seed addition experiment in the Prachatice region. We have two pairs of historically disturbed and undisturbed sites. We will observe the survival of the sown resident species in the gaps and vegetation.
Additionally, we collected data on the deadwood found in the close vicinity of each seedling plot.
We are still growing seedlings of the most common tree species in open gardens and under closed canopies to investigate the intraspecific variability of leaf traits.

In Papua New Guinea, we have focused on maintaining our permanent seedling plots and celebrated their 10th anniversary with another seedling survey and a new round of canopy photos taken above them. We were happy to welcome the first-ever female assistant, Lena, to our team!

We sampled litter for decomposition experiment at disturbed and undisturbed localities with communities with different litter decomposability in the České Budějovice and Prachatice region. Also, Reynoutria japonica will serve as easily decomposable and Calamagrostis epigejos as recalcitrant litter.

Eva conducted this year's last seedling census in the Prachatice multi-condition experiment. The survival experiment is conducted in both vegetation and competition-free gaps. The species do not perform well in competition, and the best performing species is Plantago lanceolata.
Yann Hautier from Utrecht University was visiting our working group. He gave a talk at the Ecology Seminar entitled Biodiversity and temporal stability of naturally assembled ecosystems across spatial scales. We had nice discussions about his projects, but also ours.
ITV of SLA appears to be driven by trait convergence, which indicates environmental filtering for this trait. SLA is a highly variable trait filtered toward optimal values. This allows more efficient capture of light energy and to occupy a broader range of conditions.

A new publication led by Ondra, now published in @jvegsci.bsky.social is the result of fieldwork by almost our entire working group. We examined the intraspecific trait variability of 15 Carex species across South Bohemia.

The courses are focused on theory in ecology and related fields as well as on data analysis and interpretation. Large part of the study is based on individual student research. Feel free to share further.

Šuspa led an excursion for students and the public at the weekend. Roasting sausages and a visit to the pub were included. Šuspa has demonstrated many nice plants, among others, Blechnum spicant, Potentilla norvegica, and Scirpus radicans. Photos by @eusic.bsky.social

The autumn weeding of the multisite experiment near Prachatice is finished. Focal species are colonising plots at 16 localities. Ingrowth cores were also installed in each plot. We managed despite the rocky soil and some rainy days. @terezasvancarova.bsky.social @jsegrestin.bsky.social

Now, while weeding the multisite project near Prachatice, we look back at the Ohrazení weeding in August. As communities are stabilising and the weeded biomass is lower, we managed to do all three experiments in one day (plots of Šuspa, Aleš and Helena).

Milan Štech, Šuspa, and @mariekonecna.bsky.social were at the botanical weekend for high school teachers in Slavkov, near Český Krumlov. Many students attended. They went to Vyšenské kopce and other protected areas. @terezasvancarova.bsky.social came to demonstrate measurements of photosynthesis.

September is the time of excursions. Šuspa and Péťa were in Mohelno last week with 30 students. Not only were plants demonstrated, but also animals, as ornithologist Kryštof Korejs was also present.

Lucka is working now on her bachelor thesis on the relationship of the diversity of ants and ant-dispersed plants, myrmecochores, across different habitats. Now she started the ant sampling. @mariekonecna.bsky.social
The interview is in Czech: budejovice.rozhlas.cz/negativni-vl...
Another interview on this topic (also in Czech) is here: www.jcu.cz/cz/univerzit...
Aleš and @mariekonecna.bsky.social were guests of the radio program Dopolední host (Morning guest) in Český rozhlas České Budějovice. They discussed the loss of diversity in connection to the recent global study they co-authored: www.nature.com/articles/s41...

In each pair, one locality was strongly affected by human influence, while the other was as little affected as possible. We did two relevés at each locality and measured traits of all species. We managed in two days, Šuspa joined for one day.
After six years, Aleš, Eva, and @mariekonecna.bsky.social resampled their #DarkDivNet core plots in Novohradské hory. Relevés in pairs of mesic meadows, beech forests, and waterlogged spruce forests were done.
