Invasive lionfish respond to ambient soundscapes, but only at night- perhaps because vision is less reliable? 🐟🪸 #ASABWinter2025

🚨 New paper alert! 👀 In our new opinion piece in TREE @cp-trendsecolevo.bsky.social, we propose #cephalopods as model systems to investigate the link between tactical #deception and #cognition in animals 🐙🦑🪄✨🧠

Tactical deception in cephalopods: a new framework for understanding cognition
Many animals rely on deception, including signalling misinformation, to gain advantages
over others. While many deceptive strategies rely on deterministic patterns or conditioning,
some taxa can flexi...

🚨Our new paper is out now in Biological Invasions. Using a #citizen_science approach, we find correlations between #invasive #lionfish abundance, the length of time invaded, and human #hunting pressure in the western #Atlantic and #Caribbean Sea. doi.org/10.1007/s105...
Citizen science reveals relationships between human hunting pressure and the abundance and behaviour of invasive lionfish (Pterois spp.) - Biological Invasions
Predation can shape the distribution and abundance of animals in an environment, with a major source of predation in some systems now coming from humans. However, measuring the influence of human acti...

An interesting day spent at the 1st European #Lionfish Conference in Crete and a great visit to the aquarium and HCMR.Thanks @kotrschal.bsky.social for organising.

🚨Our new paper is out NOW in @ecol-evol.bsky.social 👀 Here we show that prior exposure to dynamic illumination can have a persisting effect on the visual perception of 🦀, reducing their ability to detect predators even after the dynamic illumination has ended.

Motion After‐Effects Induced by Dynamic Illumination in Crab Vision
While in humans, background motion can disrupt the detection of visual cues even after the moving background component has ceased, it remains unknown whether natural forms of background motion might ...

Lionfish (Pterois volitans) Show Social Attraction to Conspecifics When Selecting Shelters
Group formation in animals can arise from two primary mechanisms: individuals aggregating over resources, or individuals socially benefiting from interacting with conspecifics. Distinguishing between...

🚨Excited that the first chapter from my PhD is now out in Marine Biology. Here we show that #lionfish do not show any directional preferences for ambient #soundscapes during diurnal hours.
