Staff profile

Martina Kadin, MSc, is a PhD student at Stockholm Resilience Centre.

Her main areas of interest are seabird population dynamics and behavioural ecology, with a specific focus on the effects of fisheries and fish stock dynamics. Martina has also a broad interest in governance of marine resources with a particular focus on the Baltic Sea. She is a member of the Coastal and marine social-ecological systems theme.

Martina has a MSc in marine ecology from Stockholm University and her thesis work was focused on sexual maturation and survival of immature common guillemots in the Baltic Sea. In addition, she has undergraduate studies in mathematics and GIS. Martina has developed her pedagogic skills from teaching assignments in biological statistics and marine ecology.

In her PhD studies Martina focuses on the interaction between seabirds and pelagic fish. Particularly, her research studies demographic processes, such as survival and reproductive success, as well as foraging strategies and chick provisioning. Using field data on the alcid Common murre Uria aalge, Martina is investigating how these variables may be impacted by changes in food abundance and food quality, directly linked to fisheries targeting the same species but also indirectly when effects cascade through the food-web. Certain fishing practises may also result in birds drowning in fishing gear causing additional mortality, and Martina’s PhD project aims to assess the influence of bycatch on population viability. Martina’s work forms a part of the research project Baltic Seabird.

Martina works with statistical tools such as generalized linear models, additive models and mixed models, as well as combinations of them. Another important method is capture-mark-recapture modelling of ringed birds, where she mainly works with multi-state models. These models allow e.g. different causes of mortality to be modelled separately or survival rates to differ between sites and reproductive state.

She is also interested in how seabird studies can engage people in the challenges our seas are facing, through classic approaches like public lectures and popular science to participatory field studies and projects linking seabird ecology and art.

Previous projects
Martina was a project team member in the Best Practice Project funded by the Baltic Sea 2020 foundation. The project collected the global knowledge concerning potential solutions to the ongoing fisheries crisis forming a report aiming to provide a knowledge base feeding into the process of revision of the European Common Fisheries Policy.

She was responsible for a project within the governmental assignment “Marine Economic Information” for the Swedish Environmental Protection Agency. The project concerned the future ecological consequences of not taking further action to improve the state of the Baltic Sea and the Skagerrak
