1/ New paper @pnas.org on the structure of mutualistic #networks between individuals plants and frugivore species.

Last chapter of @elequintero.bsky.social's PhD thesis

doi.org/10.1073/pnas... #ecopubs
Downscaling mutualistic networks from species to individuals reveals consistent interaction niches and roles within plant populations Species-level networks emerge as the combination of interactions spanning multiple individuals, and their study has received considerable attention over the past 30 y. However, less is known about the structure of interaction configurations within species, even though individuals are the actual interacting units in nature. We compiled 46 empirical, individual-based, interaction networks on plant-animal seed dispersal mutualisms, comprising 1,037 plant individuals across 29 species from various regions. We compared the structure of individual-based networks to that of species-based networks and, by extending the niche concept to interaction assemblages, we explored individual plant specialization. Using a Bayesian framework to account for uncertainty derived from sampling, we examined how plant individuals “explore” the interaction niche of their populations. Both individual-based and species-based networks exhibited high variability in network properties, lacking remarkable structural and topological differences between them. Within populations, frugivores’ interaction allocation among plant individuals was highly heterogeneous, with one to three frugivore species dominating interactions. Regardless of species or bioregion, plant individuals displayed a variety of interaction profiles across populations, with a consistently-small percentage of individuals playing a central role and exhibiting high diversity in their interaction assemblage. Plant populations showed variable mid to low levels of niche specialization; and individuals’ interaction niche “breadth” accounted for 70% of the population interaction diversity, on average. Our results highlight how downscaling from species to individual-based networks helps understanding the structuring of interactions within ecological communities.

Interesting new #ecopubs @pnas.org

Seed production failures are more spatially synchronized than mast peaks across temperate tree species

But local synchrony among species is low, so generalist seed consumers unlikely to experience coordinated starvation–satiation

doi.org/10.1073/pnas...
Geography of masting creates greater synchrony in seed scarcity than in seed abundance Interannually highly variable and synchronized production of large seed crops by perennial plants, called masting, drives resource pulses and famines with cascading effects on food webs. While the spatial scale of masting synchrony is well documented, it remains unclear how synchrony differs between years of seed abundance and failure, and how such dynamics extend across species and space. These gaps are important to resolve, as they determine the magnitude and spatial extent of masting effects on food webs. Using a 36-y dataset from 431 sites spanning seven dominant tree species in temperate Europe, we provide evidence that seed failures are more spatially synchronized than mast peaks, indicating that regional coherence in seed production is structured primarily by reproductive failure. Among-species synchrony was localized. This suggests that in temperate forests, mobile seed consumers are unlikely to experience coordinated starvation–satiation cycles, in contrast to highly synchronous tropical dipterocarp systems. From an applied perspective, failure years affect seed availability over broad regions, limiting sourcing options for afforestation and restoration, and underscoring the value of spatially explicit masting forecasting. Because mast peaks and failures differ fundamentally in their food web consequences, our findings highlight the need to better understand and anticipate the ecological impacts of synchronized seed scarcity.

This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!

"How can funders avoid crossing the Szilard point?"

The Szilard point is "the threshold at which the total cost of competing for a grant equals (or surpasses) the value of the available funding."
Point of no returns: researchers are crossing a threshold in the fight for funding
With so little money to go round, the costs of competing for grants can exceed what the grants are worth. When that happens, nobody wins.

Qianjiadong Reservoir in southern Hunan, China, produces a double harvest: solar energy and yellow carp. The solar farm produces up to 80 megawatts of power while the fish forage beneath the panels. With a massive scale-up of solar and wind at home and cheap exports of the technology, China is driving a worldwide surge of renewable energy—Science’s 2025 Breakthrough of the Year.

Earth's largest land animals are limited by salt.

Sodium availability constrains the density and distribution of elephants, giraffes and rhinos across Africa, and offers a new explanation for the so-called 'missing megaherbivores'.
