I saw this work presented at #ICN2026 and it's absolutely gorgeous and mind-blowing!! Cannot recommend enough, a must read!!! The videography alone is *chef's kiss* 🤌

1/8 Breathing seems automatic. But it's a finely tuned motor behavior that has to be controlled. In this preprint, I map the circuits that match a fly's respiration to the metabolic demands of flight and mitigate the risk of dehydration. 🧵🪰 www.biorxiv.org/content/10.6...

Here's the working prototype of my setup. It's a 3D-printed black block with a socket to hold a watch glass, and a 3D-printed diffuser that sits on top of the block. Recessing the glass greatly reduces stray light & glare. #NaturalHistoryCollections #Macrophotography #FocusStacking #DIYImagingStage

This is a close up of the imaging set up I made to image the water penny. There's a 3D printed black block with a socket to hold a standard watch glass on the left, with an actual watch glass sitting atop the block on its right edge. On the right edge of the block is a off white 3D-printed diffuser, roughly shaped like a hollowed out hemisphere, with large circular openings on the top and bottom. The bottom rim of the diffuser fits into a recess on the top of the block holding the watch glass. The pieces are setting on a light grey bench top in front of a white wall.

I've been working on a better setup for capturing focus-stacked images of immature insects in alcohol...and it's working well. 🙂 #NaturalHistoryCollections #Macrophotography #FocusStacking #Psephenidae #APennyForYourThoughts

Ventral view of a water penny larva (Psephenidae) against a black background. The six legs, antennae, and the feathery gills are all clearly visible—and would be well protected from above when the larva is clinging to a rock underneath the water.

New methods preprint! doi.org/10.64898/202... Are you interested in #tracking 3D movements of animals into reconstructions of habitats using #photogrammetry? I'm specifically tracking #mantisshrimp but our approach could be adapted to other animals. Please reach out with questions or feedback 😊

Tracking animal routes in 3D space through reconstructed habitats from dynamic videos

Contextualizing the movements of animals into their three-dimensional (3D) habitat contexts is still a major challenge for fields relying on animal tracking methods. This promises to change as Structure-from-Motion photogrammetry tools and techniques revolutionize image processing into the truly 3D spatial realm, by enabling reconstructions of habitat models from overlapping photographs. Combined with tracking data, these techniques would help elucidate drivers behind animal movements that have been previously masked by two-dimensional approaches. Unfortunately, tracking methods are often still impractical for use with understudied or non-model animals, especially those living underwater. In this paper, we describe a method for tracking the translational movements of animals into a photogrammetric habitat model. Our approach spans three general parts: (1) filming the navigation paths of wild animals by following individuals with small cameras (GoPros) on extendable sticks whilst SCUBA diving, (2) reconstructing a 3D spatial habitat model from separate footage, and (3) manually plotting the 3D trajectories of animals into the habitat model. We used one popular commercial software for photogrammetric reconstruction, trajectory plotting, and measurement of trajectories, after which the plots can be exported in a variety of formats for further analyses. Straightforward and flexible methodologies such as this stand to encourage more fieldwork concerning animals that live in structurally complex habitats, or animals that are underrepresented in movement or navigation research. We expect that this approach can be adapted to study many aquatic or terrestrial animals in different habitats, and at various scales. ### Competing Interest Statement The authors have declared no competing interest.

📢 Heads-up: I'm currently finalising the job description for a 30-month postdoc modelling visual abilities in these very gorgeous and very dead creatures! If you're interested, please get in touch - anticipated start is late 2026/early 2027 and the project combines great colleagues in UK + S Korea!

So excited to have received an #HFSPResearchGrant to study trilobite eyes with Luke Parry @oxuniearthsci.bsky.social and Gil Ju Lee (Pusan National University)!🥳 I'll be recruiting a postdoc @bristolbiosci.bsky.social - if 3D data, optical modelling, and fossils tickle your interest, stay tuned!

Seals have a superpower: they are the only mammals with amphibious hearing! They hear well both in-air and underwater. My collagues and I have a new study in Proceedings B on the origins and evolution of amphibious hearing in pinnipeds 🦭🔊🧪 doi.org/10.1098/rspb...

Very important new paper out! The coffee berry borer beetle is the worst pest of ☕️ worldwide, and in Mexico is attacked by the wasp Cephalonomia hyalinipennis. That wasp is supposed to be in Hawaii, so why doesn’t it attack CBB here? Turns out neither are actually C. hyalinipennis!
