Our team analysed the correlation of N deposition with numbers of territories of 112 Swiss breeding birds species. Insectivous and herbivorous species were more negatively associated with N deposistion, as well as ground-nesting species. Read more here: doi.org/10.1111/cobi...

Hey seabird folks - have you ever thought "*ANOTHER* talk about ?!" So did we.
So we reviewed 3000 conference abstracts to see which species get the spotlight. Huge work from @ingridpollet.bsky.social with me and @seabirdsentinel.bsky.social

Zoals verwacht komt de Ministeriële commissie Economie en Natuurherstel niet met een oplossing voor de stikstofproblematiek. Het kabinet kiest ervoor om de natuur verder te laten verslechteren en ondernemers nog eens 10 jaar in onzekerheid te laten zitten. nos.nl/artikel/2564...
Kabinet wil uitstoot stikstof in 2035 halveren
Vrijdag komt het kabinet met de contouren van het nieuwe stikstofbeleid. Leidend daarbij wordt de uitstoot van stikstof bij de bron, dus bij boeren en bedrijven zelf.
