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)

Had an amazing time at #ESJ73 last week in #Kyoto -- 5 students from the Tohoku U Macroeco Lab gave oral presentations and 3 presented posters, with one winning a prize! Congrats, Shen-san!

Had a really amazing time at @biogeography.bsky.social 2025 in Aarhus, where I presented prelim results from our lab for mapping functional and response diversity to estimate ecosystem service provisions. Many thanks to the organizing team & volunteers. Looking forward to the next #TIBS in Beijing~

@EcographyJourna We go through a SDM workflow and explain all the tools we can use from various pkgs for each step, highlighting how they can work well in unison. We also use sdmverse to show the main functional groups for SDM pkgs, and give suggestions on where pkg dev should go...

Just back from Minamisanriku on the NE coast where my lab and collabs installed wildlife cameras, microclimate sensors, and sound recorders to monitor biodiversity in beautiful mountain forests. We are all happy, but <exhausted>....

Last week we had a great kickoff meeting for a grant to build a new marine science research center at @TohokuUniPR with @JAMSTEC_PR~ My lab will be participating in <biodiversity modeling>! I joined the panel disc. about long-term monitoring, stability, and societal impacts.

Visited @OISTedu to work with @SamRPJRoss and colleagues on our SHINKA grant research on response diversity of lake plankton communities. Hardly felt like I'd been gone a while, let alone nearly a whole year... Hope to come again soon! View from the new Lab 5 building~

@Trends_Ecol_Evo @Wil_Thuiller @AkiraSMori We argue that 4 advances in particular (below) can improve predictions for #ecosystem services (a.k.a. NCPs) and explain promising applications. We also describe how these improvements can help us meet goals of international frameworks for...

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.

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.

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).

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.

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.

Just returned from an excellent time at EAFES 2023 in beautiful Jeju Island, Korea, where ecologists from all over East Asia shared research and began new int'l collaborations. Great experience, looking forward to the next one! @esjoffice @TohokuU_Lifesci

Yesterday saw how raccoons in Kyoto leave signs of their night revels on temples and shrines. Now on train to Osaka!

Seems like if I was 15 now, this is all I'd do. And I'd apparently be learning to code, too. nyti.ms/1Wu9p0H
