Blaise Martay

Senior Research Ecologist

Based in BTO Scotland, Blaise is a Senior Research Ecologist in the Framing Futures team and co-leads a group that maintains oversight in this work area, particularly related to the impacts of, and responses to climate change. Blaise carries out ecological research, primarily on climate change impacts and adaptation.

Interests & Responsibilities

Recent projects have included multi-taxa modelling of the impact of climate change on UK biodiversity, and the impacts of phenological mismatch and insect abundance on swallow productivity and populations. She was also responsible for a project to engage school children in collecting extensive UK-wide data on soil invertebrates and birds.

Much of her work involves combining BTO's large-scale datasets with data from other national monitoring schemes and she recently contributed to the 2023 global review: Climate change and migratory species: a review of impacts, conservation actions, indicators and ecosystem services. This report was presented by the UK government at the 2023 UN Climate Change Conference. 

Blaise has a broad interest in conservation ecology. In particular, she is interested in disentangling the impact of climate and land-use factors on populations to identify vulnerable species and populations, drivers of change and to predict future changes. This encompasses examining shifting species interactions, such as bird-insect interactions.

Blaise is also interested in research into the best use of conservation practices such as agri-environmental schemes and habitat protection and restoration.
