BONUS‐BAMBI has provided new knowledge on three key species in the Baltic Sea

Bladderwrack Idotea baltica Stickleback Experimental work show that reproduction in bladderwrack will be negatively impacted by forcasted decreased salinity

Rothäusler et al 2019 Phycologia

Biomass of bladderwrack and Idotea balthica predicted to significantly decrease

Kotta et al 2019 Scientific Reports

Large genetic diversity is predicted to facilitate rapid adaptation and population persistence in three‐spined sticklebacks

Heckwolf et al 2018 Evolutinary Applications

BONUS‐BAMBI has provided new general modelling tools and approaches

Stickleback

New state‐of‐the‐art modelling method to predict species distributions

Kotta et al 2019 Scientific Reports

New modelling tools for genetic dynamics of metapopulations provide new genetic targets and guidelines

Hössjer et al 2014, 2015, 2016 Mathematical Bioscienes, Theoretical Population Biology

New approaches for combining species distribution with biophysical dispersal and connectivity models

Jonsson et al 2018 Biodiversity and Distributions

High risk of locally adapted genotypes being unable to shift ranges fast enough due to ristricted disperal and long generation time

The knowledge message is clear:

• Genetic diversity of Baltic Sea species is unique
• Represents local adaptations also within the Baltic
• Genetic diversity maximizes the potential of future

adaptation and survival

• Genetic knowledge exists that is directly applicable

in management

BUT: Knowledge on genetic diversity is insufficiently recognized and used in practical management

Sandström et al 2019

The knowledge gap needs bridging in Baltic Sea management

Exceptions! General conservation goals for genetic diversity are included in MPA plans

64 HELCOM MPAs 161 management plans Genetic diversity is not mentioned in MPA management plans

Why is genetic knowledge ignored?

The interviewed Baltic Sea managers think genetic is important ... BUT:

We need more knowledge and resources!

We need guidance

• n how to include

genetic concerns in management!

How can existing information be of practical use for management?

Sandström et al 2016 Biodiv Conserv

HELCOM MPAs Do not specifically target genetic diversity or locally adapted populations There are equal amounts of genetic diversity within as compared to outside MPAs Improvements: protect areas with

• locally adapted populations
• high levels of genetic diversity
