Senate’s tax bill seeks to gut clean energy; Musk calls it β€˜utterly insane’ The Republican-controlled Congress is poised to score a major win for President Trump by repealing green energy incentives that Democrats passed in 2022.

This is so depressing. Ceding the future to other countries while we make our air dirtier and our planet hotter. Gift link, if you dare. Really hope this horrible bill fails completely.

Another step towards linking animal migration and population dynamics using integrated modelling! The secret lies in a neat equation relating survival and transition probabilities between migratory regions

Post‐migratory nonbreeding movements of birds: A review and case study While many migratory birds are conceptualized as using a single wintering site, technological advances that enable detailed tracking of individual birds are uncovering more examples of post-migratory....

Post-migratory movements in the nonbreeding season are in fact displayed by a surprising number of birds around the world, with diverse resource- or weather-based cues. Two former students in the lab wrote a paper documenting examples of this: onlinelibrary.wiley.com/doi/full/10....

Long-billed Curlew and 'Akikiki may be an ocean apart, but they have at least one thing in common: They both benefit from funds coming from the United States federal budgeting (AKA, appropriations) process. πŸͺΆ

Are you looking to get a graduate degree in Fisheries, Wildlife, and Conservation Sciences? This funded MS project at OSU is focused on testing a range of non-invasive method for small mammals (enclosed camera trapping + thermal cameras mounted on drones) against SCR applied to live trapping data.

It turns out it's possible to estimate unbiased breeding to nonbreeding transition probabilities with a weighted bootstrap, as long as one has migration data from all nonbreeding regions and estimates of the relative abundances of those regions.

Through simulation, we show that this approach often generates biased transition probability estimates with bidirectional migration data. How then to integrate these increasingly common data types?

Earlier we had developed methods for estimating transition probabilities and MC (a measure of migratory connectivity strength) using statistical bootstrapping (doi.org/10.1111/2041...), but only from unidirectional migration data.

In this paper, we show how one can integrate bidirectional migration data (e.g., animals whose breeding location is known and nonbreeding location is estimated with animals whose nonbreeding location is known and breeding location is estimated) to estimate migratory transition probabilities.

Migratory connectivity, the linkages of migratory populations between seasons, is a rapidly growing field. As more migration data from multiple sources become available, flexible methods to estimate migratory transition probabilities using data integration are key.
