ChiroEcho: extending automated bat vocalisation classification beyond the learned taxonomy
ChiroEcho is a deep learning framework that jointly predicts bat species and genus, then uses genus predictions together with geographic species distributions to identify species not present in the training taxonomy. By incorporating geographic constraints, the system expands its effective taxonomy, enabling classification of 41 out of 48 native European bat species—an increase from 73% to 85% coverage. The study demonstrates that limited evaluation data can mask species‑level performance and that combining coarse predictions with external constraints can recover labels for unseen fine‑grained classes.

Active Learning for Biodiversity Monitoring: From Label Efficiency to Reliable Ecological Inference
The paper discusses how active learning (AL) can alleviate the expert annotation bottleneck in biodiversity monitoring by selecting the most informative samples under a fixed budget. It highlights that while AL reduces labeling effort, its non-random sample selection complicates model validation, calibration, and ecological inference, issues often overlooked in current studies. The authors review existing AL research across acoustic and image data, identify gaps such as limited species coverage and lack of real-world deployments, and propose a tutorial framework and roadmap for developing AL methods that support efficient training, reliable validation, and trustworthy ecological conclusions.

Can Edge-Deployable Vision-Language Models Identify Species?
arXiv:2609. 11916v1 Announce Type: new Abstract: Camera traps often run in the field on edge hardware with limited or no connectivity, making small, locally-deployable vision-language models (VLMs) -- not frontier-scale ones -- the practically relevant class to evaluate for species identification.

SAGE: A sampling-aware global evaluation benchmark for species distribution modeling
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.

Hierarchy-Aware Supervised Uncertainty Estimation for Black-box LLM Taxonomic Reasoning
The paper introduces a method for estimating uncertainty in hierarchical taxonomic reasoning produced by black‑box large language models (LLMs). By extracting proxy features with an open‑source tool and training lightweight supervised estimators that incorporate hierarchy‑aware supervision, the authors predict rank‑wise correctness. Across three LLMs, these estimators outperform token‑likelihood baselines, raising micro AUROC from 0.57 to 0.75–0.80, with a rank‑specific multi‑head design delivering the best results.
