Introduction
I am a plant ecologist who is fascinated by biodiversity. Currently, I am working as a PostDoc at the Remote Sensing Center for Earth System at the University of Leipzig. There I investigate the interactions between biodiversity and climate change. I am seeking to understand if biodiversity can buffer climate change effects such as drought. For that, I use terrestrial laser scanning (structure and reflectance patterns) as response to biodiversity effects.

Description
- I am interested in the interactions between biodiversity and climate change. I work within the excellence cluster "Breathing Nature" seeking to understand in different ecosystems how biodiversity buffers climate change extreme events.

Humans modify ecosystems and biodiversity worldwide, with negative consequences for ecosystem functioning. Promoting plant diversity is increasingly suggested as a mitigation strategy. However, our mechanistic understanding of how plant diversity affects the diversity of heterotrophic consumer communities remains limited. Here, we disentangle the r...
The significance of biological diversity as a mechanism that optimizes niche breadth for resource acquisition and enhancing ecosystem functionality is well‐established. However, a significant gap remains in exploring temporal niche breadth, particularly in the context of phenological aspects of community dynamics. This study takes a unique approach...
Earth observation data is key for monitoring vegetation dynamics across temporal and spatial scales. The most widely used method to estimate vegetation properties from Earth observation data is vegetation indices. However, temporal dynamics in vertical leaf angles can strongly alter reflectance signals and, hence, vegetation indices. Here, we deriv...
Soil is central to the complex interplay among biodiversity, climate, and society. This paper examines the interconnectedness of soil biodiversity, climate change, and societal impacts, emphasizing the urgent need for integrated solutions. Human‐induced biodiversity loss and climate change intensify environmental degradation, threatening human well...
Climate extremes are on the rise. Impacts of extreme climate and weather events on ecosystem services and ultimately human well‐being can be partially attenuated by the organismic, structural, and functional diversity of the affected land surface. However, the ongoing transformation of terrestrial ecosystems through intensified exploitation and man...

Vertical leaf angles and their variation through time are directly related to several ecophysiological processes and properties. However, there is no efficient method for tracking leaf angles of plant canopies under field conditions.
Here, we present AngleCam, a deep learning‐based approach to predict leaf angle distributions from horizontal photog...
To characterize the canopy volume of the grassland community, we calculated volume based on the voxelization technique. Hence, for each scanned
plot, a voxel grid with a resolution of 5 cm was created, and the volume was then calculated as the product of the cell area and the attributed height. Further, we split scanned plots based on the voxel gri...
We performed a non-destructive measurement of plant community canopy structure and for that we used a terrestrial laser scanner (TLS). We calculate voxel grids of the 3D point clouds we used the function ‘vox’ from the R package VoxR. Volume calculation based on voxel grid generate the variables evenness and center of gravity. To calculate canopy v...
The positive relationship between plant species richness and plant productivity is
supposed to be driven by complementarity effects. Based on annual
measurements, long-term biodiversity experiments support complementary effects
and reveal their strengthening with maturity of the plant communities. However,
we still lack information on if and how th...
Increasing plant diversity commonly enhances standing biomass and other ecosystem
functions (i.e., carbon fluxes, water use efficiency, herbivory). The standing biomass is correlated
with vegetation volume, which describes plant biomass allocation within a complex canopy structure.
As the canopy structure of plant communities is not static througho...
Canopy structure is an important driver of the energy budget of grassland ecosystem and is, at the same time, altered by plant diversity. Diverse plant communities typically have taller and more densely packed canopies than less diverse communities. With this, they absorb more radiation, have a higher transpiring leaf surface and are better coupled...
This poster shows that plant diversity controls the mean surface temperature of plant communities via vertical canopy structure while
in August, horizontal canopy structure. Additionally, we won the 2019 Highly Commended Poster at the BES Conference.
Locally, plant species richness supports many ecosystem functions. Yet, the mechanisms driving these often‐positive biodiversity–ecosystem functioning relationships are not well understood. Spatial resource partitioning across vertical resource gradients is one of the main hypothesized causes for enhanced ecosystem functioning in more biodiverse gr...
Biodiversity often enhances ecosystem functioning likely due to multiple, often temporarily
separated drivers. Yet, most studies are based on one or two snapshot measurements
per year. We estimated productivity using bi-weekly estimates of high-resolution
canopy height in 2 years with terrestrial laser scanning (TLS) in a grassland diversity
experi...
In experimental systems, biodiversity enhances ecosystem functioning, but the underlying mechanisms are still subject to debate. Although ecologists have gone a long way to separate the mechanisms experimentally and statistically, most studies are based on one or two annual measurements of ecosystem functions although these functions are likely dri...
Understanding the mechanisms driving the dynamics of plant communities is still a challenge for ecologists, in particular in tropical forests, where species number are substantially higher than in temperate regions and population sizes are lower, respectively. Mainly two theories have been discussed intensively in this context. The neutral theory o...
We analyzed the influence of landscape configuration on fruit production and its effects on frugivorous birds in 17 forest fragments at the Atlantic Plateau of Sao Paulo. In each fragment 3 transects (100 m length) with 5 collectors were set up (in total 255 collectors). Birds were captured using 120m of mist nets along the central line. The first...
