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 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.

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.

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.
