Long overdue, but the main results of my metacommunity experiment are finally out! Different aspects of spatial network structure shape ecological dynamics at different scales—connectivity boosts biomass overall, but locally it can do the opposite. 🔬🧫🌐

One in six species on Earth experienced extraordinarily high temperatures across more than 25% of their range in 2024--the hottest year on record. For most, this was the second year of extreme heat, likely compounding risks. In PNAS: www.pnas.org/doi/10.1073/...

Excited to share our new paper on how empirical research can better support mechanistic models—through realistic, interdisciplinary data and by embracing complex, individual-level mechanisms. Born from a @ecologicalsociety.bsky.social symposium! doi.org/10.1111/2041... @methodsinecoevol.bsky.social
Graphical abstract illustrating four recommendations for ecological modeling with aquatic animals.

Be interdisciplinary and across levels: Includes icons for population biology (a bar chart of age structure) and behavioral ecology (a pie chart showing habitat use), plus a zoomed-in illustration of individual porpoises within a group.

Use mechanistic modeling instead of statistics as a conceptual framework: A curved line plot shows respiration increasing with temperature, with data points color-coded by temperature and a shaded area indicating stressful conditions.

Emphasize realism over precision: Shows a fish in a naturalistic habitat with plants and conspecifics, contrasted with a lone fish in a bare tank.

Include stressful conditions: Reiterated through both the curved plot and a separate graph with three treatments, where respiration increases across treatments and with temperature, with the highest temperature range shaded in red.

Warming can affect many physiological processes. But any attempt to scale up individual-level processes to population-level consequences must assume a relationship between temperature & the strength of density dependence. But what does it look like? In our new paper, we tried to find out.
