Abstract

ABSTRACT. In the last two decades the use of species distribution modeling (SDM) for the study and management of marine species has increased dramatically. The availability of predictor variables on a global scale and the ease of use of SDM techniques have resulted in a proliferation of research on the topic of species distribution in the deep sea. Translation of research projects into management tools that can be used to make decisions in the face of changing climate and increasing exploitation of deep-sea resources has been less rapid but necessary. The goal of this workshop was to discuss methods and variables for modeling species distributions in deep-sea habitats and produce standards that can be used to judge SDMs that may be useful to meet management and conservation goals. During the workshop, approaches to modeling and environmental data were discussed and guidelines developed including the desire that 1) environmental variables should be chosen for ecological significance a priori; 2) the scale and accuracy of environmental data should be considered in choosing a modeling method; 3) when possible proxy variables such as depth should be avoided if causal variables are available; 4) models with statistically robust and rigorous outputs are preferred, but not always possible; and 5) model validation is important. Although general guidelines for SDMs were developed, in most cases management issues and objectives should be considered when designing a modeling project. In particular, the trade-off between model complexity and researcher’s ability to communicate input data, modeling method, results and uncertainty is an important consideration for the target audience. RÉSUMÉ. Au cours des deux dernières décennies, le recours à la modélisation de la répartition des espèces pour étudier et gérer les espèces marines a considérablement augmenté. La disponibilité des variables prédictives à l’échelle mondiale et la convivialité de ces techniques de modélisation ont entraîné la multiplication des recherches sur la répartition des espèces en haute mer. La traduction des projets de recherche en outils de gestion pouvant servir à prendre des décisions dans le contexte des changements climatiques et de l’exploitation accrue des ressources en haute mer est moins rapide, quoique nécessaire. Cet atelier visait à discuter des méthodes et variables pour la modélisation de la répartition des espèces dans les habitats en haute mer, et à établir des normes pour évaluer les méthodes de modélisation pouvant aider à atteindre les objectifs en matière de gestion et de conservation. Pendant l’atelier, les approches envers la modélisation et les données environnementales ont fait l’objet de discussions, et des lignes directrices ont été élaborées. Celles-ci comprenaient les caractéristiques souhaitées qui suivent: 1) les variables environnementales devraient être choisies selon leur importance écologique a priori; 2) l’ampleur et l’exactitude des données environnementales devraient être prises en compte durant la sélection d’une méthode de modélisation; 3) dans la mesure du possible, les variables substitutives, comme la profondeur, doivent être évitées si des variables causales sont disponibles; 4) les modèles dont les résultats sont statistiquement solides et rigoureux sont privilégiés, mais leur utilisation n’est pas toujours possible; 5) la validation du modèle est importante. Même si des lignes générales sur la modélisation de la répartition des espèces ont été mises au point, les objectifs et enjeux de gestion devraient généralement être pris en compte pendant la conception d’un projet de modélisation. En particulier, le compromis entre la complexité du modèle et la capacité du chercheur à communiquer les données d’entrée, la méthode de modélisation, les résultats et les incertitudes sont des facteurs importants pour le public cible.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
