The preprint presents AutoMaxEnt, a repository of functions and tools designed to automate maximum entropy species distribution models (SDMs). The authors position AutoMaxEnt as a flexible environment that reduces the manual intervention typically required when producing reliable SDMs, while still permitting user control over key modelling choices.
Species distribution models are widely applied to assess and analyse species' spatial distributions and their responses to environmental changes. Despite being a mature research area, SDM workflows often require substantial researcher input and bespoke decision-making at multiple steps. The authors argue that this per-species customization, while necessary because species respond uniquely to environmental factors, limits the ability to apply SDMs consistently and with confidence across large sets of species.
AutoMaxEnt is presented as a collection of tools targeting the automation of maximum-entropy SDMs. The primary aims described in the source are to:
These design goals emphasize scalability—supporting the application of species distribution models across many species—and flexibility, preserving options for user-guided scenario generation when desired.
According to the abstract, AutoMaxEnt automates the bulk of data pre-processing and preparation required for running maximum-entropy SDMs. While specific preprocessing steps are not itemized in the abstract, the general claim is that the routine handles typical preparatory tasks so that users can focus on higher-level decisions or permit automated scenario exploration. The source does not report implementation details, exact preprocessing operations, or example pipelines; those would need to be consulted in the repository or full manuscript.
AutoMaxEnt offers functionality to control model fit and to automate model and variable selection. The abstract indicates the tool facilitates not only fitting models but also evaluating them and selecting among alternatives. The authors highlight the capacity to run these processes across different species and temporal or geographic scopes, enabling comparative or large-scale analyses without per-species manual reconfiguration.
The abstract does not report which evaluation metrics, model selection criteria, or statistical thresholds are used; users will need to review the code repository or full paper for those specifics.
A feature explicitly noted in the abstract is support for multiple algorithms to generate background points (pseudo-absence or background sampling strategies) and options to configure the study area. These are common and important choices in presence-only modelling with maximum entropy approaches, and AutoMaxEnt includes configurable alternatives for these steps. The abstract does not list the exact background-sampling algorithms implemented or default behaviors; that information is available through the repository link provided in the source.
The authors emphasize that AutoMaxEnt offers a balance between automation and user control. Users can allow automated generation and exploration of multiple model scenarios or exert control over how scenarios are generated. This dual approach is intended to make the workflow accessible for large-scale, automated analyses while retaining the ability to tailor modelling choices when species-specific knowledge or bespoke analyses are required.
The abstract notes a public repository for AutoMaxEnt (GitHub link reported in the source record). The preprint states that the authors declared no competing interests. The work is posted as a bioRxiv preprint and has not been peer reviewed.
The abstract does not report implementation specifics, performance results, benchmark comparisons with other SDM automation tools, example case studies, usage examples, or computational requirements.

AutoMaxEnt is positioned as a toolkit to reduce manual workload in building species distribution models with maximum-entropy approaches, offering automated preprocessing, model/variable selection, background sampling alternatives, study-area configuration, and batch model fitting/evaluation across species and time periods. The preprint invites users to access the code repository for implementation details; because the article is unreviewed, users and practitioners should examine the repository and supplementary material and consider validation before applying AutoMaxEnt in production or decision-critical contexts.
