Insects in the #Amazon could reach their heat thresholds. Rising temperatures already threaten dung beetles. A study conducted by scientists from #Würzburg and #Bremen shows this trend. @ecoresearchzoo3.bsky.social @kimholzmann.bsky.social ➡️ www.uni-wuerzburg.de/en/news-and-... 📸 Kim Lea Holzmann

Kim L. Holzmann @kimholzmann.bsky.social · 25/03/2026
Dung beetles, providing important ecosystem functions, might be already showing decreasing diversity (biotic attrition) due to high temperatures. Microhabitats and forest connectivity along the Amazonian-Andean gradient are crucial to maintain and conserve biodiversity.
000
Kim L. Holzmann @kimholzmann.bsky.social · 25/03/2026
While temperature and soil moisture (but not resources) explained overall diversity patterns along the gradient, this failed to explain the drop in the lowlands. Including critical temperatures improved the model, indicating that lowlands might be already too hot for heat-sensitive species 🔥
121
Kim L. Holzmann @kimholzmann.bsky.social · 25/03/2026
For a mechanistic understanding we also tested thermal limits of dung beetles. As we showed for all insects in a previous article in Nature (doi.org/10.1038/s415...), also dung beetles in the lowlands have the smallest thermal safety margin.
100
Kim L. Holzmann @kimholzmann.bsky.social · 25/03/2026
We sampled dung beetles using baited pitfall traps along a forested gradient from 250-3500 masl, and found the highest diversity at 500 masl with a remarkable drop in the lowlands.

While orthopterans 🦗 showed the highest heat tolerance, flies 🪰 appeared as the most sensitive group. Intact forests with high complexity, shade and connectivity are of high importance to prevent (further) species losses in the Earth's most biodiverse area.

Kim L. Holzmann @kimholzmann.bsky.social · 04/03/2026
Importantly, we compared heat tolerance with surface and air temperatures predicted under three climate change scenarios. Most vulnerable are insects in the Amazonian rainforest, where over 50% of future air temperatures could induce a heat coma in half of the insect community.

Kim L. Holzmann @kimholzmann.bsky.social · 04/03/2026
In addition, we used a deep learning model to predict the melting temperature of 1000 proteins in over 600 species. We found a high correlation of physiological thermal limits and protein stability, indicating that heat tolerance might be founded in fundamental protein architecture.

Kim L. Holzmann @kimholzmann.bsky.social · 04/03/2026
We sampled ~8000 insects along two large elevational gradients and tested their thermal tolerance. Upper thermal limits declined with elevation and more closely related taxa had similar limits. Lowland insects did not show plasticity to adapt to higher temperatures.

Are you a PhD-level #wildlife ecologist committed to research and education for #biodiversity and nature restoration? Our group at @utrechtuniversity.bsky.social has a #vacancy for an assistant professor! Deadline for applications is February 19. Please spread the word. www.uu.nl/en/organisat...
Restoring nature and reversing biodiversity loss are urgent societal challenges. Utrecht University invites applications for an Assistant Professor in Wildlife Ecology and Nature Restoration. In this role, you contribute to help solve these challenges through research and education by linking fundamental wildlife ecology to biodiversity recovery and nature restoration.

As an Assistant Professor, you will join a young, enthusiastic team that is eager to make an impact. You will help strengthen the team’s mission to connect fundamental wildlife ecology with the challenges of nature restoration in human-dominated multifunctional forest landscapes, especially in north-western Europe. 

Your research will focus on restoration-relevant themes, such as wildlife responses to anthropogenic change, the effectiveness of conservation interventions, and the contribution of wildlife to biodiversity recovery and nature restoration. Close collaboration with colleagues within and beyond Utrecht University is an important part of this role, as well as building sustainable partnerships with conservation practitioners and policymakers. 

You will combine fieldwork, experiments and biomonitoring (e.g. using sensor technologies) with laboratory, statistical and theoretical approaches. There is ample opportunity to initiate research projects and to acquire funding. 

In education, you will teach in the Biology programs, develop and coordinate a new course, and supervise research projects of BSc, MSc and PhD students.
