A bigger picture
We research the sea and its function for humans and the environment
The Helmholtz Institute for Functional Marine Biodiversity (HIFMB) is a research institute located in Oldenburg. It researches marine biodiversity and its importance for the function of marine ecosystems. In doing so, it develops the scientific basis for marine nature conservation and ecosystem management.
Master Thesis Project
The HIFMB Project Group Plankton Ecology is looking for a candidate for a master thesis with the topic: “Tracking the diversity and dynamics of marine bacterial and metazoan communities through environmental DNA analysis”.

Oceans are not only the richest in species but also the largest habitat – due to their depth, oceans make up more than 90 percent of the total habitat on earth.
They regulate the climate, bind CO2 and are an important food source for humans. Every second breath we take contains oxygen from the ocean.
In order for the sea to continue to fulfil these functions, which are also important for humans, intact habitats are needed. And these in turn depend on marine biodiversity, i.e. the diversity of species, genetic variants of each species and ecosystems.
How strongly and in what form this biological diversity reacts to global warming and human-induced influences is still largely unclear today.
Marine ecosystems are changing – also and especially through human influence. According to a recent study, for example, only 13 percent of the oceans can still be described as wilderness.
What do the changes in marine ecosystems mean for us and what measures do we take to counter them?
Our approach is interdisciplinary: At HIFMB, scientific research goes hand in hand with social science expertise in the analysis of social and political processes.

“Faktencheck Artenvielfalt” – and then?
In October 2024 the first Germany wide biodiversity assessment “Faktencheck Artenvielfalt” was published. The HIFMB led the writing process of the chapter on status and changes of coastal and marine biodiversity, their drivers and consequences, as well as options and needs for action to improve its status. The assessment compiled information and data from numerous …

The international seabed is the ‘common heritage of mankind’ (or humankind). In principle then, it your heritage, and mine. It is a place, as global citizens, we have rights to. But is it somewhere we can actually access? How can we enact our rights to the seabed?
Photosymbioses: A Coincidence of Evolution?

Inside COP 16 (United Nations Biodiversity Conference)
Government representatives, international organizations, scientists, NGOs and many more are meeting in Cali, Colombia, until 1 November to develop strategies to protect biodiversity and negotiate concrete measures. Dr Ute Jacob from the HIFMB Transfer Office has an official observer status and is on site in Cali.
