Publication: Phylogenomic analyses uncover origin
and spread of the Wolbachia pandemic
Of all obligate intracellular bacteria, Wolbachia is probably the most common. In general, Wolbachia are either widespread, opportunistic reproductive parasites of arthropods or essential mutualists in a single group of filarial nematodes, including many species of medical significance. To date, a robust phylogenetic backbone of Wolbachia is lacking and consequently, many Wolbachia-related phenomena cannot be discussed in a broader evolutionary context. In an iDiv funded study a scientist team with the participation of Dr. Christoph Bleidorn (University of Leipzig) presented the first comprehensive phylogenomic analysis of Wolbachia supergroup relationships based on new whole-genome-shotgun data. The results suggest that Wolbachia has switched between its two major host groups at least twice.

iDiv scientists submit study to help reaching the international targets by 2020
Representatives of more than 190 countries have come together at the 12th meeting of the Convention on Biological Diversity (CBD) in Pyeongchang, Republic of Korea, to assess progress towards the 20 Aichi targets of the CBD. The meeting examines the conclusions of the Global Biodiversity Outlook 4 report, which shows that despite increasing efforts, including a remarkable expansion in protected areas, it is unlikely that most of the targets will be met by 2020, if we remain on our current trajectory. Recently a study published in "Basic and Applied Ecology" by a team of 22 experts – including scientists of iDiv and the Martin Luther University – proposes a framework to get countries back on track to the Aichi targets. This framework can be used by countries to identify actions that address simultaneously multiple targets, reducing the overall efforts needed to implement the 2020 Biodiversity Strategy.

Biodiversity research for our future
Over the last 20 years, biodiversity research has been established and shaped as a young interdisciplinary research field. In light of the global biodiversity crisis, however, this research is under pressure related to time and expectations and investments are necessary. The German Centre for Integrative Biodiversity Research (iDiv) is funded by the German Research Foundation (DFG) since October 1, 2012, and will become a hub for biodiversity research.
The German Centre for Integrative Biodiversity Research (iDiv)
- concentrates expertise across city and state borders
- brings together top scientists
- connects theoreticians and empiricists of manifold research fields
- focuses on theory and synthesis (synthesis centre sDiv)
- educates a new generation of scientists in transdisciplinary biodiversity
research (graduate school yDiv)
- communicates the importance of safeguarding biodiversity
