Associate Professor at Tohoku University, Japan. I run the Macroecology Lab: macroecolab.github.io We model species' distributions and biodiversity patterns and make predictions over space and time. (ported my old tweets here)

New paper out! In this one with @ndimhypervol.bsky.social, @rdinnager.bsky.social, @economo.bsky.social, and Ale Casadei-Ferreira, we show that some commonly used ENM/SDM permutation tests can be badly derailed by not accounting for sampling bias. nsojournals.onlinelibrary.wiley.com/doi/abs/10.1...

As happy as I am that the most extreme carbon emission scenario has been deemed infeasible, I am kind of sad to see it go. RCP8.5, we had some good times together modeling climate change risks for species. www.nytimes.com/2026/05/26/c...

With island-wide and high-frequency sampling , we show that land-cover change can diminish natural seasonal patterns for insects. As loss of these patterns is linked to loss of crucial ecosystem services, we need more research on how global change affects ecological seasonality.
000
Jamie M. Kass @ndimhypervol.bsky.social · 12/10/2023
We also found greater temporal mismatch (i.e., lower synchrony) for communities of native and uncertain species in developed areas, but the opposite pattern for confirmed alien species.
100
Jamie M. Kass @ndimhypervol.bsky.social · 12/10/2023
But maybe site differences in climate were responsible, or maybe some sites had species that were just more/less variable. We tested these and found 1) no patterns for regional or in situ temp., and 2) the same species were more seasonal in forests and less so in developed areas.

Jamie M. Kass @ndimhypervol.bsky.social · 12/10/2023
The ant activity time-series include seasonality patterns, but also trends and randomness. So we decomposed the time-series to isolate these components and examined relationships with land-cover change. High seasonality in forest (left) dropped for more developed areas (right).

Jamie M. Kass @ndimhypervol.bsky.social · 12/10/2023
We sampled >1 million ant workers biweekly for 2 years in varied habitats across Okinawa Island and found that as forest (top) transitioned to more developed areas (bottom), the natural drop in activity during winter seemed to disappear, and community variability also decreased.

Jamie M. Kass @ndimhypervol.bsky.social · 12/10/2023
The data is from the OKinawa Environmental Observation Network (OKEON), which samples 24 sites across various environments on Okinawa Island. The network also measures soundscapes (birds, insects), monitors mammals with camera traps, and collects arthropods.
