Odor Tracking in Aquatic Animals

Panayiota Siskos ’23 Animals use intermittent chemical cues to help avoid predators, find mates, and find food. The speed at which some animals forage shows that more instantaneous sensory feedback is also used. Lobsters have multiple sensors to gather information, including sensilla on antennules with chemosensory cells that detect chemical concentrations and mechanosensory cells that find flow and direction. Several are conditionally rhythmically active and … Continue reading Odor Tracking in Aquatic Animals

An Evolutionary Arms Race: Speed and Hunting in The African Savannah

By Maryna Mullerman ’20 Prey must run faster than predators to avoid getting killed, while predators must overwhelm prey to avoid starving. There have been numerous studies published on predator-prey relationships, but little research has analyzed high-speed savannah animal locomotion. Alan M. Wilson and researchers from the Royal Veterinary College at the University of London aimed to analyze the locomotor characteristics in two predator-prey pairs: … Continue reading An Evolutionary Arms Race: Speed and Hunting in The African Savannah
