Description

 

[NEW!!] Open Project for PhD, MSc and BSc students [NEW!!]

 

 
Type of job: 
Bachelor and Master theses
PhD project
 
Supervisor: 
Ting-Wen Chen (ting-wen.chen@upb.cas.cz)
 
Consultant:
 
Characteristics: 
Food is fundamental for life continuation, not only for aboveground biota but also for belowground animals. The soil represents a black box where different organic entities such as litter, detritus, bacteria, fungi, algae and root exudates are mixed. The ample food resources likely support hundreds of invertebrate species living together without competition. By combining advanced approaches such as stable isotope, neutral lipid fatty acid, digestive enzyme activity and DNA gut content analyses, we are able to draw a more comprehensive picture from different aspects of the food resources used by the soil animals, thereby to understand the drivers of species coexistence in soil.
 
Objectives: 
In this international cooperation project we will investigate the trophic niches of multiple species of springtails (Collembola) and oribatid mites (Oribatida). Students involved in this project will benefit from learning from, working in, and exchanging between two research groups in Czechia and Germany: (1) Institute of Soil Biology (ISB), Biology Centre, Czech Academy of Sciences and (2) Department of Animal Ecology (AG Scheu), University of Göttingen. 
 
Material and Methods: 
• We will sample soil animals in Spring and Autumn from the permanent study sites in South Bohemia that represent a successional gradient from an arable field to a forest.
• We will identify Collembola and Oribatida to the species level with the helps from the taxonomists at ISB.
• We will measure digestive enzyme activities at the ISB and conduct stable isotope and fatty acid analyses in the AG Scheu at University of Göttingen.
 
 

About me

Research Interests

Compared to aboveground ecosystems, soil preserves a greater biodiversity. My researches focus on species coexistence in soil. What are the processes driving community assembly patterns? Which roles has evolution played in contemporary species assemblages? To answer the questions I apply both phylogenetic and trait-based approaches to soil mesofauna (mainly Collembola and Oribatida) inhabiting different terrestrial ecosystems.
