Leipzig University seeks to fill the following position at the German Centre for Integrative Biodiversity Research (iDiv), Flexpool, in Leipzig from 1 October 2020 onwards.

Background

The German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig is a National Research Centre funded by the German Research Foundation (DFG). It is located in the city of Leipzig and jointly hosted by the Martin Luther University Halle-Wittenberg (MLU), the Friedrich Schiller University Jena (FSU), the University of Leipzig (UL), and the Helmholtz Centre for Environmental Research (UFZ). For more information please visit: www.idiv.de.

The Evolution & Adaptation research group (Dr. Renske Onstein) focuses on the interchange between (macro-) ecology and evolution, to understand the global distribution of genetic, taxonomic and functional diversity. We investigate microevolutionary processes to understand how these play out over macroevolutionary time scales. Understanding these patterns and the processes underlying them is important for predicting how adaptable biodiversity is to current and future global change.

The Project

Madagascar harbours exceptional biodiversity, but this tropical hotspot also faces increasing threat from human activities and climate change. Plants with large, ‘megafaunal’ fruits are common across the flora of Madagascar, especially within the palm (Arecaceae) family. However, Pleistocene-Holocene extinctions of large-bodied ‘megafaunal’ fruit-eating and seed-dispersing animals (such as giant lemurs) may have hindered the dispersal of taxa with megafaunal fruits. In this project we aim to investigate the molecular, micro- to macroevolutionary consequences of dispersal limitation in palms, specifically focusing on adaptive evolution of a megafaunal-fruited palm, Hyphaene coriacea, using a comparative framework of Madagascar (all megafauna extinct) and mainland Africa (where H. coriacea is still frequently dispersed by elephants). Specifically, we aim to
(1) identify candidate genes for fruit and seed traits important for plant-frugivore interactions,
(2) pick up genetic traces of selection or adaptation in relation to dispersal by smaller-bodied frugivores, and
(3) evaluate the macroevolution of candidate genes or gene families across the palm family.
This project integrates the fields of plant evolution, molecular evolution and plant-frugivore interaction ecology. It will be in collaboration with researchers from Hohenheim University (Professor Philipp Schlüter) and University of Miami (Professor Mauro Galetti), among others. Besides the salary, there is funding available for field- and lab work, conference visits and participation in courses/workshops.

Tasks

– Collecting genetic samples from H. coriacea individuals and populations on Madagascar and mainland Africa, and measuring their functional traits (part of these samples has already been collected);
– Collecting ecological information about the seed dispersal effectiveness (e.g., using camera traps) and demography of H. coriacea in the study areas;
– Using novel genomic and transcriptomic techniques (e.g., RAD-seq, RNA-seq) to infer candidate genes for functional traits and evaluate traces of selection;
– Writing and publishing of scientific papers in peer-reviewed journals;
– Presentation of results at international conferences;
– Doctoral researchers at iDiv benefit from an inter- and transdisciplinary training and support by the graduate school yDiv

Requirements

– M.Sc. or equivalent degree in a project-related field (e.g. molecular biology, genetics, phylogenetics, population genomics, ecology and evolution)
– prior experience using molecular techniques, preferably with transcriptomics or bioinformatics, incl. the basics of scripting/programming for handling and statistically analyzing large genetic/genomic datasets
– prior experience with tropical natural history, fieldwork and basic living conditions is advantageous
– willingness to spend several months in the field (Madagascar/mainland Africa)
– Excellent English communication skills (speaking and writing)
– innovative, able to work on his or her own initiative
– Team-oriented and strong organizational skills, in order to manage this collaborative research project within an international consortium
– independent mind and the ambition to publish in internationally leading journals
