A modeling study links fluctuating plankton growth and dispersal to abundance distributions, spatial correlations, Taylor scaling and patchiness, while exposing clear limits in seasonal and oligotrophic data.
A computational study finds that bee-like colonies can evolve shared directional signals when food is neither too scarce nor too easy to find, and that a later shift to a gravity-referenced code can remain viable under many tested settings.
A new arXiv preprint reports a reconstruction ensemble that combined multiple cryo-EM ab initio jobs. It achieved 97.4% accuracy on a 45-class asymmetric synthetic benchmark, versus 34.6% for the best single-shot run, and separated four major ribosomal assembly states from junk in an unfiltered experimental stack.
A mathematical analysis of pooled subtree information finds a sharp contrast: three-leaf buckets can hide distinct labelled tree pairs, while n-1 buckets recover pairs across broad size ranges, with small exceptions.
This preprint derives a critical genome-length formula for fragmentation in a mating-threshold population, with scaling laws that change as population size, mutation rate and transient genealogical width vary.
A new preprint combines blood-cell measurements with computer simulations to examine how Gaucher disease-associated red-cell changes relate to deformation, confined flow and viscosity.
An abstract genotype–phenotype model associated higher penetrance with mutational robustness and lower access to alternative high-fitness regions, while simulations linked infrequent environmental change with penetrance and frequent change with adaptability.
The SWEB model estimated crop water use and root-zone soil moisture across Australian grain regions, with correlations of 0.70 to 0.85 across most regions and higher errors in southeast Australia.

A new arXiv preprint proposes one continuum-mechanics framework for bounded, unbounded and proportionate tissue growth. Its central results are theoretical: the model predicts a stress threshold, long-term proportions set by material parameters and a turnover-dependent growth rate, but it does not test those predictions against biological measurements.
A modeling preprint suggests that near-perfect correlations between species are not a universal sign of ecological instability; the signal depends on whether a slowly relaxing mode is visible above background fluctuations.
A new arXiv preprint develops models in which reproduction and survival favor different trait values and their selection strengths vary across space or time. The analysis predicts shifted optima, asymmetric or potentially two-peaked effective fitness landscapes, and wider or displaced distributions of simulated trait outcomes.
