OMAmer - tree-driven and alignment-free protein assignment to subfamilies OMAmer is an alignment-free protein family assignment method designed to avoid overly specific subfamily predictions and to scale efficiently to phylogenomic databases containing thousands of genomes. It relies on an innovative approach that uses evolutionarily informed k-mers for alignment-free mapping to ancestral protein subfamilies. This dataset provides precomputed OMAmer databases derived from the Hierarchical Orthologous Groups in the OMA Browser . We aim to update these databases with every new OMA Browser release. Each OMAmer database is built using the latest version of the OMAmer package available at the time of the corresponding OMA Browser release. The dataset includes databases for different subsets of the species taxonomy. In most cases, we recommend using the LUCA.h5 database, which contains information from all species in the OMA database. The subset-specific databases are mainly useful when disk space is limited. The release May2026 is based on the OMA Browser release May 2026 which comprises 2983 species. We used OMAmer version 2.1.0 to build these databases.

1. Many migratory birds now reach their Arctic breeding grounds earlier in order to keep pace with advancing springs and shifting nutrient peaks, either by departing earlier from non-breeding grounds or by travelling faster. For dark-bellied brent geese, there is limited potential to travel faster, as their migration to the Siberian breeding grounds is already among the fastest of Arctic geese and swans. Earlier departure would require reaching departure body mass earlier, either through a faster accumulation of energy stores during spring staging or via adjustments earlier in the annual cycle. 2. We examined long-term shifts in spring staging phenology and changes in winter and spring body mass trajectories of brent geese at the population level, with particular emphasis on the effects of winter temperature on body mass and spring body mass on departure timing. 3. We used more than five decades of body mass measurements from individuals caught in the United Kingdom and France, and in the Dutch Wadden Sea to reconstruct changes in spring and winter mass trajectories, respectively. These data were combined with over five decades of migration counts in the Netherlands and more than two decades of counts in Denmark to quantify changes in spring staging phenology. 4. We found that brent geese have not shifted their spring arrival in the Wadden Sea but have advanced departure timing. Furthermore, brent geese were heavier during and after milder winters, and have changed mass trajectories over recent decades. They no longer lose mass during winter and the second spring staging phase, and fuelling rates in the first spring staging phase have declined. Annual variation in body mass was not related to annual departure timing. 5. These results suggest that milder winters have relaxed energetic constraints and improved body condition in brent geese throughout the non-breeding season. Our findings highlight the importance of considering the full annual cycle when assessing how animals with limited capacity to adjust migration timing or speed respond to global change.

This record contains the trained autoencoder, extracted encoder, and processed world/real-river latent-space reference cloud associated with the manuscript *A data-driven approach to discern the curvature spectral complexity of compound meander bends*. The full autoencoder is provided to support reconstruction-based validation and reproducibility of the learned representation. The extracted encoder is provided for inference and future software tools. It maps preprocessed 64 × 64 single-channel curvature-spectrum images to the two-dimensional latent space used to analyse meander shape complexity and skewness. The file `world_latent_cloud.npy` contains the two-dimensional latent coordinates of the world/real-river meander dataset used as the reference background cloud in the manuscript latent-space figures. This file is a processed latent-coordinate dataset only; it does not contain raw satellite imagery, raw centreline geometries, or training images. The release includes model weights, architecture files, model summaries, export metadata, the world/real-river latent cloud, example inference scripts, a validation script, environment files, and a minimal example input. The models should only be applied to curvature-spectrum images generated consistently with the preprocessing workflow described in the associated manuscript. Main files included in this release are: - trained_autoencoder.h5: full trained autoencoder. - encoder_only.h5: extracted encoder in HDF5/Keras format. - encoder_only.keras: extracted encoder in native Keras format. - model_architecture.json: full autoencoder architecture. - encoder_architecture.json: encoder architecture. - model_summary.tx and encoder_summary.txt: layer summaries. - world_latent_cloud.npy: world/real-river reference latent-space cloud. - world_latent_cloud_metadata.json: metadata for the world/real-river latent-space cloud. - model_card.md: intended use, inputs, outputs, limitations, and citation guidance.

Despite the proliferation of social vulnerability assessment methodologies, selecting the most appropriate model remains a critical challenge due to inter-model variability. To explore the inter-model variability, this study systematically investigated inter-algorithmic and inter-classification variability to assess how methodological design influences outcomes.

================================================================================ README ================================================================================ Dataset Title: Observation points, movement-proxy data, and high-resolution land cover map for the common blackbird ( Turdus merula ) in Angers, France Version: 1.0 Authors : Mimet, Anne ; Gourmelon Damien ; Oulhen, Thomas ; Vergondy, Amandine Date of biological data collection: Observation points : 15/05/2025 to 06/06/2025 Movement-proxy data : 19/04/2024 to 17/05/2024 -------------------------------------------------------------------------------- DESCRIPTION -------------------------------------------------------------------------------- This dataset contains observed presence/absence of blackbird flights across streets, as well as point observations of the common blackbird across Angers, France, during spring. The data were used to create a connectivity model for the common blackbird in Angers. The 68 point observations provided information on the land cover types used as a possible resource by the common blackbird. The presence/absence of flying blackbirds across 190 streets in Munich was used to derive the resistance of the urban landscape to the movement of common blackbirds in a landscape connectivity model. For the point observations, the presence and absence of the common blackbird was visually and acoustically confirmed after 5 minutes of observations within a radius of 25 m. Movement presence/absence was observed along 50 m street transects. Street transects were observed for 9 minutes, and the presence or absence of common blackbirds crossing this street was recorded. The observation points and movement-proxy data were selected along gradients of greenness and traffic density. -------------------------------------------------------------------------------- FILE LIST -------------------------------------------------------------------------------- 1. movement_proxy.shp Site-level data containing presence and absence of common blackbirds crossing the sampled streets, as well as covariates such as the number of pedestrians passing during the sampling period, geographic information, information on the weather, time of sampling, pseudonomized observer.

This repository contains the processed datasets used to analyse the spatial relationship between artificial light at night (ALAN) and Arctic fire occurrence. The dataset includes cumulative ALAN layers, binary masked ALAN layers, fire polygon shapefiles, and a final analysis table. The cumulative ALAN layers provide aggregate digital number (DN) values representing light intensity. The masked ALAN layers are binary rasters, where values of 1 indicate lit areas and values of 0 indicate unlit areas. Fire scar centroids were generated from the fire polygons and used to calculate the distance from each fire scar to the nearest lit area. The final analysis table contains the distance to the nearest lit area for each fire scar and control points. The fire polygon shapefile includes fire scars for the period 2001-2013.
