This paper is part 2 of my "magnetic pulse trilogy"

Part 1: www.doi.org/10.1098/rsif...

for the most interesting 3rd Part see: doi.org/10.1098/rsif...

for some ecological insights into the magnetic sense for songbird migration Ecology see our dedicated review paper: doi.org/10.1111/brv....

Possible explanations for this finding are so extensive, that they would notfit into a bluesky post, so see the discussion of the paper itself: doi.org/10.1242/jeb....

(iv) the change in direction within the first 50-100 km. --> no bird group changed flight direction significantly

(iii) the direction in which the birds departed (in the first 5-20 km). This was a factor where former studies found differences after pulse treatment --> but here: no effect

(ii) the time within the night, when the bird depart and resume migration --> no significant difference.

We observed different stopover decisions using the #motus wildlife tracking system. [Blue is always the control group, red the group of birds, who recieved the magnetic pulse]:

(i) the probability of the bird resuming migration in the first night after the treatment --> no significant difference!

We tried to influence the proposed magnetic-particle based magnetoreceptor of migratory European Robins on Stopover on Helgoland by a short but strong magnetic pulse. According to current hypotheses this should disturb the magnetic map of the birds and should lead to altered migratory behaviour

3rd anniversary of this paper: Karwinkel et al. 2022 "A magnetic pulse does not affect free-flight navigation behaviour of a medium-distance songbird migrant in spring" in JEB, where we tried to reproduce old studies on magnetoreception, but found no effects. A thread:

Spread the word: we're #hiring! We have an open #research fellowship position for #postdocs with their own research idea: It includes an own budget, a #PhD student position and the possibility to conduct independent research on animal #navigation and/or #magnetoreception 🧭🦤🦇🐟⚛️🧪👩‍🔬! sfb1372.de/jobs

Today it is already 2 years ago, that I recieved the honor to call myself "Dr. rer. nat." thanks to @migecol.bsky.social and @ifv-whv.bsky.social for making this possible!

Today is the 1-year-anniversary of our extensive Review-Paper: "A conceptual framework on the role of magnetic cues in songbird migration ecology" doi.org/10.1111/brv....

- it is a must-read, when you work with magnetoreception and birds!

new publication by our team member @thiemokarwinkel.bsky.social about the multi-year and multi site tracking of long-tailed ducks (Clangula hyemalis) from the Arctic to the Baltic Sea. @ifv-whv.bsky.social read here open access: onlinelibrary.wiley.com/doi/10.1002/...

In a new article, we summarise the opportunities of the #Motus Wildlife Tracking System from a European perspective. This #tracking method offers a wide range of opportunities for research of small migratory birds, bats and insects: conbio.onlinelibrary.wiley.com/doi/full/10....

After PhD on ecological role of #magnetoreception in #songbirds, he continued researching offshore songbird migration using #Motus tracking

His research theme:
From Patterns & Pathways to Protection: Understanding mechanisms of #birdmigration for #conservation

Marine artificial light at night: Implications and potential hazards for offshore songbird and bat movements in the Greater North Sea Human activity in the North Sea is intensifying, which amplifies the need to understand better the biological implications of human activities in the ecoregion. Here we aim to characterize the impact...

NEW PERSPECTIVE ARTICLE
In a team combining bird and bat migration scientist with ecological economics, we draw attention on the threat of artifical light at night to migrating songbirds and bats to inform science-driven politics. See our article here: doi.org/10.1111/csp2...

In Research, Ignoring Female Birds Harms Scientific Understanding A new study shows that ecological research often ignores or excludes data on female birds and behavior, resulting in erroneous assumptions on conservation.

The first paper of your PhD is always so exciting! 🤩 An all-#Galbatross effort, "A focus on females can improve science and conservation!" See press release (www.audubon.org/news/researc...) and the study here: onlinelibrary.wiley.com/doi/10.1111/...! #FemaleBirds #FemaleBirdDay

New project! Ever wondered about shifting #baselines in #conservation? Thought about quantifying historical biodiversity losses? We launched a nationwide #resurvey of historical bird surveys in Germany. Together with www.dda-web.de, we have...
