Her role is to develop and test methods that are field deployable, aiming to achieve rapid results in various environments.
Jonathan supports the group as a Laboratory technician in various projects. One of these is the BurGeoN project, which uses the characterisation of environmental DNA to investigate the relationship between geological features and the formation of lineages. As limited mountain regions have a remarkably high diversity with many young endemic and rare species.
He is responsible for a variety of tasks in the molecular laboratory including processing the environmental DNA (eDNA) samples from the DNA extraction in a cleanlab to the library preparation. As an environmental engineer and nature lover, biodiversity is a very important topic for him.

Virginie’s research focuses on integrating molecular ecology tools via the use of environmental DNA (eDNA) to unravel the mechanisms shaping biodiversity patterns across ecosystems. Within the group, she is part of the SPI Greenfjord project, which plans to investigate the impact of melting glaciers on the marine ecosystem in Greenland fjords by relating physical properties and geochemical fluxes to biodiversity measured using eDNA metabarcoding. At the Arctic scale, she also aims at studying the spatial structure and drivers of marine food-webs properties.

Harnessing this novel approach should help advance real-time biodiversity and species monitoring.
Sarah is captivated about natural history museum collections - which are precious archives documenting the biodiversity. For her project, she highlights the value of those collections by exploiting museum specimens to develop a global genetic reference database of fishes and sharks. She will subsequently use this reference catalog to reanalyze eDNA metabarcoding samples collected over all oceans to determine fish and shark community composition.

In his PhD, Zili focuses on the macroevolution of the plant biodiversity in the Hengduan Mountains, China, which is a biodiversity hotspot. Different from a classical phylogenetic or population genetic analyses, in his study, taxonomy-centered sets of analyses will be carried out, contrasting sister species pairs regarding their geographic and ecological separation; along with analyzing of different genera and species richness across the Hengduan mountains, a better understanding of diversity which shaped Henduan mountains diversity as it is today can be outlined.

Bastiaan researches links between aquatic and terrestrial food webs in Swiss forests. The structure of food webs is crucial for maintaining biodiversity, while this is heavily influenced by global changes, both in climate and land management. However, terrestrial, aquatic and interconnected food webs may respond differently to these changes. During his PhD project, Bastiaan will utilize field work, mesocosms, feeding experiments, stable isotope and fatty acid analysis in order to unravel the effects of forest management and climate change on links between aquatic and terrestrial food webs. Bastiaan’s PhD is a part of the Blue-Green Biodiversity project and he is supervised by prof. dr. Martin Gossner (WSL), prof. dr. Carsten Schubert (EAWAG) and prof. dr. Loïc Pelissier (ETH).
Rama’s project, in collaboration with the University of Zurich, College of Forestry Ponnampet, and ATREE, aims to understand the effect of land use change on shaping the structure of plant-pollinator interaction networks in the coffee agroforestry of India. Using a combination of advanced landscape mapping, observational data, pollen metabarcoding, and eDNA approaches, we aim to understand how the plant-pollinator network dynamics are affected by local and landscape-level transitions in the land use. The plausible causal pathways affecting the structure of plant pollinator interaction networks are also assessed. The outcomes of this work can inform better land management strategies to restore biodiversity, ecosystem productivity and resilience, and sustainable agricultural production.
Using fragments of insect DNA which remain on the surface of flowers, Daisy aims to identify the bee species which pollinate flowering trees growing in coffee agroforests in Kodagu, Western Ghats of India. By constructing plant-pollinator networks from this data we could detect changing interaction patterns resulting from intensification of land use and reductions in native tree diversity. It will also reveal whether landscape and local scale land use change effects bee species differently depending on their size and life history. Understanding the fragility of these pollination interactions could help inform land management to protect biodiversity and crop security.

Theadora Laorenza
Thea's project focuses on understanding the biodiversity and evolution of amphibians in South America, particularly in the Andes mountain range - which is known to be one of the most biodiverse-rich regions for amphibians globally. As mountains are understood to be "pumps for biodiversity," her project will investigate the different processes influencing amphibian taxonomic and functional diversity associated with mountain formation. This project will further involve refining species distribution maps and correlating data on the geography and geological history of the Andes with species richness, functional diversity, and species range boundaries. The results of the project would then contribute to a better understanding of the geographic and spatial drivers influencing amphibian biodiversity in the Neotropics, which is further relevant as reference for designing appropriate conservation and landscape management strategies.
As an exchange student, Thea's project is affiliated with both ETH Zürich and Lund University in Sweden.
Albéric de Tessières de Blanzac
Albéric is currently finishing his master's in mechanical engineering at ETH. He is interested in the challenges that climate change and the energy transition represent. His project focuses on assessing the impacts of renewable energies on biodiversity in Europe in collaboration with the WSL and the EPSE. For that, he will use methods used in the ongoing SPEED2ZERO postdoctoral project of Marie-Ange Dahito at the Swiss level. The goal would be to compare the potential impacts of different energy scenarios in Europe.
