Our new Nature Communications paper shows that caterpillars are NOT safer in temperate regions as believed, if we consider also predation in forest canopies. tinyurl.com/catexNC1

GAJU to Jakub Pawlik The Grant Agency of the University of South Bohemia has awarded a two-year research grant to our PhD student Jakub Pawlik — and it’s taking our lab to more mountains. Huge congratulations to him. J…

Friday (soon to be) lab news — we are thrilled!

Huge congrats to Jakub Pawlik for securing funding for his new project in the Belledonne mountain range, exploring how elevation and warming shape spider communities.

We are back from the conference. It is Friday ... and our new paper just went online! 🎉
The results of the work indicate substantial sub-canopy warming in Southeast Asia, posing potential risks for tropical biodiversity.
The work is now out in Geophysical Research Letters.

For most lab members, it doubled as an advanced course in working under pressure — calmly navigating the chaos that come with preparing an event. As for me, in my attempt to escape the week, I learned a valuable lesson about not flying too high ...

This week’s lab highlight looks back at the Zoological Days. For our attending students, it was a great opportunity to share ideas, reconnect with colleagues, and celebrate zoology. 🎓Contratulations to Jakub Pawlik for his award for a great poster. 🏆

Endemic species maintain avian diversity and ecosystem services on the island of New Britain - Biodiversity and Conservation Endemic species exemplify both the exceptional evolutionary value and extraordinary vulnerability of tropical island biodiversity. Conservationists often face the difficult task of balancing ecosystem...

This means that conservation measures targeting endemic species may not fully conserve the range of avian ecosystem functions.

The study gives a trait-based overview of contribution of endemic species to ecosystem functioning in New Britain. While island endemics tend to be overall more vulnerable to disturbance, some functional characteristics tied to disturbance sensitivity are more prevalent among non-endemic birds.

How Endemic Birds Shape Rainforest Ecosystems on New Britain Tropical islands host unique evolutionary lineages, yet these endemic species are often highly vulnerable to environmental change. Understanding how they contribute to ecosystem functioning is esse…

🎉 FRIDAY IS HERE AND SO IS … OUR NEW PAPER! 🎉
I’m thrilled to share a brand‑new paper by — K. Korejs, R. Hazell, B. Koane, P. Toko and G. Sosanika. If you’re into island biogeography, functional ecology, or just love birds doing important ecological jobs, this one’s for you. tinyurl.com/Korejs2026

Last few hours for submitting your abstract for European Conference of Tropical Ecology in Passau in February. Don’t miss your chance to be part of this vibrant gathering of tropical ecologists. Act now — and don’t be like me, leaving it for 11 PM tonight! 😅 gtoe2026-passau.de/call-for-abs...

🐦⛰️ What drives dramatic elevational shifts in avian roles within ecosystems? Korejs, @czsam00.bsky.social and colleagues link feeding specialisation to functional diversity along a continuous 200–3700 m rainforest gradient in Papua New Guinea.

Výbor České společnosti pro ekologii (ČSPE) se ostře ohrazuje proti pozměňovacím návrhům k novele zákona č. 114/1992 Sb., které ohrožují smysl národních parků a oslabují ochranu přírody v ČR. Pokud zůstanou součástí novely, je lepší zákon vůbec neotevírat. Plné znění prohlášení:

New Paper from Oak Bodyguards Project Over several last years, I (K.Sam) was collaborating on the larger project focusing on the insect herbivory, predation, and leaf traits of oaks. I managed two study sites, near Budejovice and near …

It's Friday, after all: New publication of this week is a collaborative paper resulting from the project Oak Bodyguards. multitrophicinteractions.blog/2025/04/11/n.... Thanks to Bastien and Elena for pushing this forward and keeping me on board for years.

Spring time – submission time March is typically the month when the Grant Agency of Czech Republic has deadlines for the grant proposals. So while the older members of the laboratory were rather busy to put together some propos…

Finalizing the work with students, while kicking out the field work ... these days are busy (and the transition between grant-writing and the approaching submission is painful). multitrophicinteractions.blog/2025/04/03/s...

New Paper: Do plasticine caterpillars accurately measure bird predation? A camera trap experiment Understanding how insect-eating birds contribute to ecosystem balance is crucial for ecology and conservation. One widely used method to measure bird predation on insects involves placing artificia…

Because it is Friday, and what better way to celebrate than with another scientific revelation? We present a new contribution to science. This time, fresh from the hands of "our" postdoc Áňa Máňa and her current collaborators in France.
