Differential gene expression toward species of Aristolochia impairing the performance of the Troidini butterfly Battus polydamas

Entomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 696-707, July 2025.
We studied the response of Battus polydamas (Papilionidae) larvae fed on Aristolochia ringens (containing several diterpenes) and Aristolochia gigantea (containing sesquiterpenes and acyclic monoterpenoids but no diterpenoids or aristolochic acids). We assessed larval performance on fitness components such as survival and differential gene expression ...

Q-learning with temporal memory to navigate turbulence [PDF]

arXiv
We consider the problem of olfactory searches in a turbulent environment. We focus on agents that respond solely to odor stimuli, with no access to spatial perception nor prior information about the odor. We ask whether navigation to a target can be learned robustly within a sequential decision making framework.

Dissection of Behavioral Components and the Role of Omega/Delta Turns for the Chemotaxis of C. elegans

Genes to Cells, Volume 30, Issue 4, July 2025.
The analyses of centerline‐based posture dynamics of C. elegans during chemotaxis indicated that directional turns are achieved in a two‐step process: (1) selection of the sequence type (at least in the case of single turns) and (2) adjustment of the turning angle within the selected turn type (for a backward turn to a forward turn).

On the role of morphology and kinematics of biological swimmers to spread and suppress their odors in the wake [PDF]

arXiv
Understanding the interplay between hydrodynamics and chemical sensing in aquatic environments is crucial for unraveling biological swimmers' navigation, foraging, and communication strategies. This study investigates the role of kinematics and morphologies of fish in dispersion and suppression of odor cues in their wake.

Generation of Odorant Receptor‐QF2 Knock‐In Drivers for Improved Analysis of Olfactory Circuits in Drosophila

Genes to Cells, Volume 30, Issue 4, July 2025.
We established 23 odorant receptor (Or)‐T2A‐QF2 knock‐in drivers (Or‐QF2KI) in which the expression of the QF2 transcription factor reflects the endogenous expression of Or genes. The transgenic Or42a‐Gal4 driver only labels the Maxillary palp olfactory receptor neurons (ORNs), while the Or42a‐QF2KI driver labels the antennal ORNs in addition to the ...
