Event description

Description

Join us for some pizza and a great talk about science!

We are continuing our talks at The Frontier, thanks to a new partnership with STEM in the Park!

This time our speaker is Sönke Johnsen of Duke, who will speak about how oceanic animals hide themselves from view. http://sites.biology.duke.edu/johnsenlab/

ABSTRACT:

Hide and seek in the open sea: Pelagic camouflage and visual countermeasures

Camouflage is exceptionally challenging in open ocean environments, because they are so featureless. It is perhaps no surprise that animals that live in this world have evolved highly sophisticated camouflage strategies, three of which—transparency, mirrors, and counterillumination—are rare or absent in all other habitats. The visual systems of the predators are equally complex, and several visual capabilities, including ultraviolet and polarization sensitivity and special filters, are thought to facilitate detection of camouflaged animals. This talk reviews the optical nature of this enormous and mysterious realm and both the camouflage and camouflage-breaking strategies of its inhabitants, focusing primarily on underlying principles and what remains to be discovered. A theme throughout is that far more is known about the optical and visual structures involved than about their function, and that this imbalance is primarily due to the rarity of observations of undisturbed behavior.

Bio:

Originally trained in mathematics and art, Sönke Johnsen has studied camouflage, signaling, and nonhuman visual modalities for the past 27 years. He is particularly interested in vision and camouflage in the open ocean, but has also worked on coastal and terrestrial species, magnetoreception, nocturnal illumination, and human cataracts. His research combines mathematical analyses with behavioral and morphological studies and in situ measurements and observations. His fieldwork primarily involves open-ocean research cruises that use SCUBA and deep-sea submersibles. In addition to exploring the evolution and diversity of the optical and visual tricks that animals perform, Johnsen is interested in improving communication between theoretical and experimental scientists and between scientists and artists. Outreach is a strong focus and his research has been presented in numerous magazines, newspapers and television shows. In his spare time, he is an avid nature photographer.

BEFORE THE TALK BEGINS: Sigma Xi will be hosting a 15-minute "speed networking" meet and greet session for our pizza lunch attendees, with the help of STEM in the Park. Many of our attendees have asked for more opportunities to get to know their fellow members, rather than just sitting down with their pizza. We hope this short engagement will help increase our community connection.

RSVPs are required (for the slice count) by registering for a free ticket to this event by Monday, October 30th, at 2PM. (If you decide to come after this time, you're welcome to attend, but we might not have pizza for you.)

Thanks to a grant from the N.C. Biotechnology Center and funding from the RTP chapter of Sigma Xi and STEM in the Park, American Scientist's noontime Pizza Lunch speaker series is free and open to science journalists and science communicators of all stripes, as well as any interested member of the public. Feel free to extend this invitation to anyone who might want to attend.

Talks are co-organized with Science Communicators of North Carolina (SCONC). The RTP chapter of Sigma Xi is a co-organizer and co-sponsor, and encourages any interested scientists to get involved with the chapter and its upcoming events. We thank The Frontier for providing space.

Please RSVP to this event using your own personal email (not a listserv email, etc.), which will be used solely to send reminders for the event. We will not keep your email unless you have requested to be added to the pizza lunch list (a button to be added is available on the registration page).

PLEASE RSVP ONLY ONCE. We've found that Eventbrite will let you sign up multiple times even if you have already RSVP'd.

If you wish to be removed from this list, please email fsaunders -at- amsci -dot- org. This list is opt-in only, so you're receiving this message because you asked to be on this list. If you are a Sigma Xi member and need to update your location or contact information with Sigma Xi, please email membership-at-sigmaxi-dot-org.
