Uncovering multiscale structure in the variability of larval zebrafish navigation

The paper develops a method to analyze behavioral variability in larval zebrafish by identifying motor strategies and their transitions across different environmental cues.

A Markovian dynamics for C. elegans behavior across scales

This paper develops a Markov model of C. elegans foraging behavior that captures dynamics across scales, revealing new behavioral states and a trade-off between local and global search strategies.

Fluctuating landscapes and heavy tails in animal behavior

The paper shows that slow non-ergodic dynamics in C. elegans locomotion lead to heavy-tailed statistics, explained by time-dependent potential landscapes.

A deep learning approach to capture the essence of Candida albicans morphologies

This paper develops a deep learning system called Candescence to detect and classify C. albicans morphologies from microscopy images using a curriculum-based learning strategy and GANs.

Maximally predictive ensemble dynamics from data

This paper introduces a method to infer macroscopic dynamics from data by maximizing predictive information, applied to both physical systems and the movement of C. elegans.

Free-living marine nematodes diversity at Ponta Delgada-Sao Miguel (Azores archipelago, North-East Atlantic Ocean): first results from shallow soft-bottom habitats

The paper reports the first survey of free-living marine nematode diversity in shallow soft-bottom habitats of Sao Miguel Island, Azores, identifying 43 genera across multiple families and highlighting potential new species.

WormPose: Image synthesis and convolutional networks for pose estimation in C. elegans

WormPose is an open-source tool for 2D pose estimation in C. elegans using synthetic data and convolutional networks, validated on both synthetic and real worms.

Capturing the Continuous Complexity of Behavior in C. elegans

This paper develops a method to analyze C. elegans behavior by capturing its continuous state space, revealing both stereotyped and chaotic dynamics.

Modeling the ballistic-to-diffusive transition in nematode motility reveals variation in exploratory behavior across species

The paper models nematode motility transitions and finds species-specific variations in exploratory behavior linked to trade-offs between exploration and exploitation.
