The paper presents a method for generating synthetic plankton images conditioned on taxonomic labels to address the long‑tailed nature of automated plankton imaging datasets. A CLIP encoder is fine‑tuned on a large plankton corpus using a ranked contrastive objective that accommodates deep, ragged taxonomies, and then frozen to guide a parameter‑efficient diffusion transformer. The quality of the synthetic samples is evaluated both for distributional fidelity and for their usefulness in training downstream classifiers.

The paper introduces SAGE, a Sampling‑Aware Global Evaluation benchmark for species distribution modeling that uses GBIF records for training and sPlotOpen vegetation plots for presence‑absence evaluation across 5,771 plant species. It groups species by sampling effort and relative prevalence to assess how well single‑species and multi‑species deep‑learning SDMs perform under different data conditions. The study finds that Random Forests and DeepSDMs perform best overall, with DeepSDMs excelling for infrequently recorded species only when bias‑correction techniques are applied.
