Acceleration hotspots of North American birds’ decline are associated with agriculture Human activities might have accelerated declines of population abundance, but this acceleration remains underexplored. Using 1033 North American Breeding Bird Survey routes, we analyze abundance chang...

North American bird populations are not only declining, but they’re also shrinking faster with each passing year—particularly in regions shaped by intensive agriculture, according to a new study in Science. https://scim.ag/4bkrafP

The latest European Grassland Butterfly Indicator is out. It shows that grassland butterflies have declined by 47% since 1991, indicating a huge loss of grassland biodiversity. The data come from 16,150 transects & 15,000 volunteers. We are calling for urgent action. www.bc-europe.eu/documents/69...

US science after a year of Trump: what has been lost and what remains A series of graphics reveals how the Trump administration has sought historic cuts to science and the research workforce.

Trump has been in office for one year. We at @nature.com did a deep dive looking at the administration's disruption of science in numbers.

Take a look—the numbers are staggering. By me, @dangaristo.bsky.social, Jeff Tollefson, @kimay.bsky.social, & help from @noamross.net @scott-delaney.bsky.social

A data collection mission that began in 2012 is finally released as AVONICHE.

Designed as a companion to AVONET bird trait database and updated to Avilist taxonomy, it’s an Open Access dataset providing updated diets and a detailed breakdown of foraging behaviours used by all bird species.

The SORTEE Guidelines for Data and Code Quality Control in Ecology and Evolutionary Biology This is a Preprint and has not been peer reviewed. This is version 1 of this Preprint.

Introducing "The SORTEE Guidelines for Data and Code Quality Control in Ecology and Evolutionary Biology"

The first standardised set of data editor guidelines. Led by SORTEE with input from numerous data editors across ecology and evolution.

Ecological and evolutionary consequences of changing seasonality Climate change and other anthropogenic drivers alter seasonal regimes across freshwater, terrestrial, and marine biomes. Seasonal patterns affect ecological and evolutionary processes at different eco...

If you think the seasons are feeling… different, you may be right.
Our new review in Science (@science.org) shows that Earth’s changing rhythms could have major and underestimated consequences for life on Earth. 🌍🧵

Our global meta-analysis of changes in genetic diversity across the entire tree of life indicates pervasive loss of intraspecific diversity, but there is a glimmer of hope: conservation actions and management interventions can indeed make a difference. 👇

Hi! Would you mind adding me to the list? Thanks!

Would you mind adding me too? @ibisjournal.bsky.social Thanks!

I'm recruiting a PhD student to join my lab at the University of New Orleans starting in Fall 2025. Research topics will focus on building and using phylogenies to study the diversification of birds, with an emphasis on Neotropical bird radiations. Contact me if interested.

For my first post here, I’m happy to share our new paper just published in @ibisjournal.bsky.social Thanks to a great team effort, we made a small step forward in the study of Siberian vagrants in Europe and clarified the status of two (pseudo) vagrants: the YBW & the Sib Chiffchaff. Some results 🧵

Research weaving integrates systematic and bibliometric mapping tools such as citation networks and the mapping of the geographic distributions of research activities. This figure was adopted from Nakagawa et al. 2018 TREE.

Geographic distribution of affiliations reported in studies on topics associated with sexual selection. This is an example of the product the intern will work on using the data from screening of studies in avian migration ecology. Figure adopted from Pollo et al. 2014 Biological Reviews.
