Farmland bird conservation

We investigate breeding biology and habitat use of the Corn Bunting (Emberiza calandra) across its Central European range to establish more effective farmland bird conservation strategies. This is complemented by a EU-scale meta-analysis on the effectiveness of agricultural eco schemes (AES).

Barcoding nestling diet

Nestling diet is a key determinant of breeding success, but knowledge of its regional and seasonal variation remains scare. In pilot studies, we use metabarcoding to derive diet components from nestling feces, and evaluate how this can inform conservation of farmland birds.

Guidance for Mixed models and GLMM

(Generalized) Mixed models have become a standard analytical tool in ecology and evolution, but their implementation and thorough assessment remains a challenge. We develop accessible R templates and guidelines that cover many model families and data structures.

Flower fields as eco schemes

Sown flower fields are a core eco scheme in EU agricultural policy, and frequently used in contractual conservation. Using standardized surveys, we investigate variation in the use of different flower fields types between seasons and target species (farmland birds, leafhoppers).

Trends from monitoring data

Some monitoring schemes conduct standardized surveys in a yearly rotating subset of all study sites within the program. We use generalized additive models to derive tools for robust trend analysis from such irregularly spaced time series..

Species phenologies from citizen science data

Citizen science data allow detecting even short-term responses of animals to environmental variation. Using bird records from the Ornitho system as a test case, we develop tools to model yearly bird phenologies based on standardized presence-absence surveys.
