  • Signatures of fe-/male fertility - Using long-term selection for high fertility to decipher the genetics of increased reproductive performance

By comparing genomes of high fertility mouse lines with genomes of non-selected mice we aim to identify signatures of selection (= occurrence and frequency patterns of alleles causal for the selected reproductive trait). General applicability of results will then be tested in other mammal species (pigs, lions;) Sperm parameters to correlate male fertility will be evaluated by colleagues in the Dept. of Reproduction Biology.

The project is realized under the leadership of the FBN (www.fbn-dummerstorf.de/institutes/institute-of-reproductive-biology/units-and-groups/reproductive-cell-biology-unit/) together with other collaboration partners (IKMB Kiel, IFN Schönow, BHZP, Geolifes).

  • Invertebrate-derived DNA for monitoring (urban) Wildlife in Berlin

The use of mosquitoes and flies (in particular the blood of animals they fed on), collected in parks in and around Berlin, offers a non-invasive way to survey wildlife occurrence and distribution in cities. The meta-barcoded sequence data from the blood ingested by the insects will also be correlated to the “collection systems” (flies vs. mosquitos) to analyse the impact the choice of the “collection system” has on the outcome

This study is part of the ongoing Bridging in Biodiversity of Science (BIBs) project funded  by the BMBF (2017-2018, possible extension 2019-2020).

  • The genomic basis of convergent evolution in modern sloths (Xenarthra, Pilosa)

Although the (only) two extant sloth lineages (Bradypus and Choloepus) are separated by about 30 Mya of evolution, they both have evolved a very specialized feature - the obligatory arboreal suspensory behavior. As this similarity is superficial, it represents an extreme example of convergent evolution. In order to investigate the genomic basis of this convergent evolution we will compare whole genome sequences of sloths and other mammals, looking for signs of positive selection. The first step for this study is the sequencing of a high-quality sloth genome, which is performed in partnership with the Vertebrate Genome Project (VGP) within the Genome 10K Consortium.

  • Understanding demographic change in an expanding population through simulation modelling

Understanding the demographic pathways that affect population growth (e.g. survival, reproduction, and dispersal) is difficult as they are interconnected and undergo complex feedback loops. Based on data from a 22+ year study of the spotted hyena (Crocuta crocuta) in the Ngorongoro Crater, Tanzania, an individual based simulation model is built to understand the demographic pathways that facilitate such growth, how they may limit population expansion, and what evolutionary consequences may arise.

This project is funded by a DAAD Fellowship.

  • Conservation genomics of the Hooded Grebes Podiceps gallardoi in Argentina

The Hooded Grebe Podiceps gallardoi is a critically endangered endemic bird of the southernmost part of continental Argentina. The species very restricted reproductive conditions in lakes of basaltic pre-andean plateaus led to its discovery only in 1974. Since then, population size has dropped by 80%, leaving about 800 individuals. Identified threats include, invasive American minks, introduced trouts, and climate change. In winter, hooded grebes migrate towards the estuaries of the Atlantic Ocean returning to the plateaus in spring. A relatively constant number of individuals at each plateau during successive breeding seasons suggests that Hooded Grebes are phylopatric to breeding plateaus. We test this hypothesis using a ddRADseq approach, on populations of three different plateaus. We expect to find a significant population structure if Hooded Grebes are phylopatric to these plateaus.

  • Wild boar in rural and urban environments

We are generating and analysing wild boar population genetic data to be matched with behavioural and dietary data to test the hypothesis that there are genetic, behavioural and dietary differences between city dwelling wild boar and their rural conspecifics. In the long run we aim to identify traits reflecting adaptations to the respective habitat.

This project is conceptually led by colleagues from the “Urban Ecology Group”.

  • Population genetics in hedgehogs in the city of Berlin

By genotyping a large number of hedgehogs we test the hypothesis that the urban hedgehog population of Berlin is genetically structured. Given the highly structured urban landscape we predict that a higher structured landscape will lead to smaller subpopulations (structured meta-population). If such population genetic structure is detected we aim to identify the urban landscape barriers responsible for such structure.

  • Inferring genetic patterns of on-going recolonization of Central Europe by elusive, large carnivores using novel SNP marker systems for non-invasive samples

By developing SNP marker systems to genetically monitor European carnivores, we provide tools to understand how these elusive species co-exist with humans and recolonize densely populated areas with intensive land-use. This network project, headed by the research institute Senckenberg Gelnhausen, focused on five species: European wildcat, wolf, otter, lynx, and brown bear. Research at the IZW focused on the Eurasian lynx (Lynx lynx), the Eurasian otter (Lutra lutra) and the Eurasian brown bear (Ursus arctos arctos).
