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. 🔬🧫🌐

A brief delve into the recent science history of network theory (including food webs)

Biodiversity modulates the cross‐community scaling relationship in changing environments Organismal abundance typically declines with increasing body size, with metabolic theory predicting a universal size–abundance slope of –0.75. Using protist microcosms across gradients of species ric...

Does body size predict abundance the same way in all environments, as predicted by the Metabolic theory of Ecology? Our new study challenges this assumption. Read it here: 📄 doi.org/10.1111/ele....

The number of terrestrial vertebrate species highly thermally exposed (>25% range) over time versus the mean global terrestrial temperature anomaly (denoted by color scale of points).

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/...

Short time series obscure compensatory dynamics in ecological communities - Nature Ecology & Evolution Species synchrony is considered a major mechanism of biodiversity–ecosystem stability relationships.

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.

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!

This is figure 1, which shows seven general and spatially structured biogeographical sectors characterized from four biodiversity aspects across taxa.

Ecological assemblages may be spatially organized by both context dependency and general processes. A study in Nature Ecology & Evolution finds general patterns in the organization of regional biodiversity in biogeographical regions. go.nature.com/3FILzhN 🧪

Old carbon routed from land to the atmosphere by global river systems - Nature Using a global database of the radiocarbon content of rivers combining new and published measurements, isotopic mass balance suggests that about 60% of river CO2 emissions are derived from millennial or older carbon sources.

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.

Let us celebrate the founders of Ecology. Fred Clements, Ph. D was author of a 1905 guidebook to its practice.

Clements, by all accounts a rather imposing dude, was obsessed with making ecology a quantitative science and toward this end, invented the quadrat and transect method. 1/4
