Abstract: From object detection to successful prey capture, insect aerial predators gather appropriate cues, make fast decisions and translate them into precise motor commands. To compensate for biological delays and noisy data, some dragonflies and robber fly species employ predictive strategies, in addition to visual feedback. Aerial predation therefore presents as an ideal substrate to investigate how animals with very limited resources deal with uncertainty in decision-making. In this talk, I will focus on the strategies that predatory aerial insects use when deciding whether to attack an object. In particular, we will compare the temporal and depth cues used by robber flies and damselflies. I will link the behavior to the neural and morphological adaptations, and discuss how they match particular ecological niches and evolutionary paths.
Bio: Paloma grew up in Malaga, a coastal city in southern Spain. She obtained her undergraduate degree from the University of Queensland (Australia; 2000- 2002) majoring in Zoology and Marine Biology. While at UQ, Paloma was an undergraduate in the Justin Marshall laboratory, part of what was the Vision, Touch and Hearing Research Centre (VTHRC), directed by Jack Pettigrew. During her PhD (U. of Sheffield, UK. 2006-2009) she studied the neural basis of visually guided predation in killer flies. For her work on the adaptations that can make a miniature fly deadly she received the Capranica Prize from the Society for Neuroethology. During a short postdoc at Janelia HHMI Campus (2010-2011), she studied the neural basis of predation on dragonflies, and was awarded the PNAS Cozzarelli prize for this work. A dream opportunity arose: to study the neural basis of camouflage on cephalopods at the Marine Biological Laboratory (MBL, MA). During her time at the MBL (2011-2013), in the Roger Hanlon Laboratory, she discovered a nerve that controls the tunable skin iridescence present in squid skin, and demonstrated that cuttlefish achieve texture in their skin with combinations of ‘catch-like’ muscles. In 2013 she started her own laboratory, the Fly Systems Lab, at the University of Cambridge (UK), which she moved to U. Minnesota in 2018. Her laboratory continues the focus on high quality, integrative and comparative work on predatory aerial insects, and was recently awarded the outstanding paper prize for Fabian et al. 2022, a study of interception through obstacles. In addition to her flight work, Paloma continues to work on cephalopods via collaborative efforts with the Wardill laboratory.
