The research is performed in the coastal areas of the Baltic Sea.

The Swedish island of Gotland faces limited capacity in groundwater reservoirs and increased demand during tourist season. Desalination from the Baltic Sea is a promising method for water supply which will benefit from a forecast of harmful algae blooms.

Plants are host to a wealth of microbes, both beneficial and antagonistic, and these may be found both on aboveground plant structures and in the roots.

This project will investigate the contribution of cyanobacterial blooms to fish production and contaminant bioaccumulation in the Baltic Sea.

Identifying refugia for retreating cold-favouring species

Global climate change mitigation through the preservation of natural biological carbon sinks is of the highest importance to face the threats to our planet but poses ample challenges for society, governments and policy makers around the world.

I am fascinated by the spatial and eco-evolutionary dynamics of host-parasite interactions. We do lack some generality though: many of the existing studies have (for good reasons!) focused on single pathogen species, and on non-systemic diseases with high extinction-colonization rates.

In the world’s largest ecosystem, marine plankton form complex trophic interaction networks that are influenced by environmental conditions.

Tradeoffs and synergies in relation to other wetland ecosystem services

The cumulative effects of various human activities on coastal and marine ecosystems are a pressing problem. The seafloor is subject to physical pressures from e.g. construction, dredging, marine traffic and bottom trawling, which may co-occur with each other and with climate change and eutrophication.

This project will develop a cost-efficient program to control the invasive species Lupinus polyphyllus in Sweden.

The "Cell differentiation and coordination in tissues" group is establishing and optimizing novel methods to directly assess changes in amount and chemical composition of plant biomass from biopsies with sub µm resolution.

Parasitic symbionts play a major role in the functioning and equilibrium of carbon flow in marine food webs. But the extent and strength of zooplankton parasites are still poorly known, mainly because they are hard to detect due to their small size and mostly hidden within their hosts, and consequently frequently overseen.

In this project we study habitat preferences, population dynamics, phenology and host plant preferences in six co-occurring species of burnet moths in southern Sweden. Yearly inventories have been carried out since 2012 and currently include about 100 sites with burnet moths.

The marine ecosystem around the North Pole, the Central Arctic Ocean (CAO), is in fast transition from a permanently to a seasonally ice-covered ocean as a result of global warming. The sea-ice loss will enable summer access to the CAO for non-icebreaking ships, including fishery vessels, in the near future and this project is assessing the impact.

In this study, we are looking at how extreme weather events (in particular droughts) affect forest biodiversity.

The smallest aquatic plants on earth, phytoplankton, are responsible for the vast majority of photosynthesis.

Catarina Rydin works with Isoetes (Isoetaceae), a distinct group of lycopods that are often semi-aquatic but may also be terrestrial or grow submersed in lakes.

Baltic herring, also known as "herring" north of Kalmar Sound, was previously the most common fish and a keystone species in the Baltic Sea ecosystem, connecting lower trophic levels with higher ones.

The transdisciplinary FORCE project will identify the most effective management actions for reversing biodiversity loss and increasing resilience to climate change of the Baltic Sea coast.

Parasitic plants obtain part of or all of their nutrients from another plant. We study one of the most well-known parasitic plants, the European mistletoe, Viscum album, but parasitism has evolved 12 times within the flowering plants and some 4750 species are parasites.

Has the large scale fishery in coastal areas reduced the abundance of herring in the archipelago – a baseline study of historical data

- a study in the Central Arctic Ocean

Meringosphaera are a widespread genus of marine planktonic unicellular eukaryotes that are globally distributed, yet poorly characterized.

The experiments are performed in an open ocean symbiotic cyanobacterium by expression in heterologous systems.

This project tackles the growing environmental threat posed by PFAS (per- and polyfluoroalkyl substances) in landfills, which are increasingly recognized as potential secondary sources of PFAS contamination to surrounding groundwater and ecosystems.

The purpose of the project is to give advice to the Swedish marine monitoring groups regarding measurements of optical properties in Swedish waters, compare measurements of chlorophyll, coloured dissolved organic matter, suspended particulate matter and turbidity (turbidity), and to harmonise the measurements protocols between the Swedish monitoring groups.

The BalticHER-project studies the population structure of locally spawning herring on the Swedish east coast. The study will evaluate by cross-checking genetical and otolith chemistry methods whether natal homing is a population structuring mechanism.

Human societies are dependent on ecosystem services for the provision of natural resources, and especially so in poorer developing areas. In coastal East Africa, a sustainable ecosystem production of fish is essential for food security and sustaining human livelihood.

To counter detrimental impacts of climate change and population growth LIFAGRO will develop biobased materials for advanced agricultural applications.

The NASA Aerosol Robotic Network (AERONET) is a global network of about 600 autonomous ground-based remote sensing validation and aerosol monitoring stations that measure aerosol optical properties, such as Aerosol optical thickness and the Ångström coefficient.

Catarina Rydin's main research interest concerns the Gnetales, gymnospermous seed plants comprising the genera Gnetum, Welwitschia and Ephedra.

We will investigate how a vital group of organisms in the earth's cycle, phytoplankton, is affected by the chemicals constantly present in the environment, as well as to better understand how conditions in the environment affects the sensitivity of phytoplankton to chemicals.

Environmental and genetic effects of geothermal soil heating on timing of reproduction

Water and soils are among the most important natural resources, without action, the pressure on these resources is likely to increase as a result of growing population, evolving food demand and the effects of a changing climate.

Saltmarshes are some of the most efficient carbon sinks, but climate warming and altered land use threatens to diminish their diversity and turn them into sources of the potent greenhouse gas methane.

Small-sized pelagic fish have a central role in marine food webs as they control production of predatory fish and at the same time feed on zooplankton and indirectly control algal blooms.

PlantFish is a three year research project about the role of interactions between benthic plants and large predatory fish in coastal areas of the Baltic Sea. The project examines the functional role of vegetation and predatory fish and how they interact, with focus on the ecosystems of shallow Baltic Sea bays.

Stockholm University's new graduate school in marine, climate and environmental issues is directed towards students from diverse disciplines, interested in understanding their own research in a broad and interdisciplinary context.

Supergenes are clusters of genes that can maintain favorable trait combinations because they are inherited as a unit. Studying supergenes allows us to address fundamental questions on the origin and evolution of multi-trait adaptations and is therefore of broad significance.

Food and Water are fundamental human rights and are constantly under threat. Worldwide, and specially in developing countries such as Bolivia, Water and Soil management is a strategic area for environmentally sustainable development of cities and peri-urban areas.
