Using Enclosed Y-Mazes to Assess Chemosensory Behavior in Reptiles

Abstract: Reptiles utilize a variety of environmental cues to inform and drive animal behavior such as chemical scent trails produced by food or conspecifics. Decrypting the scenttrailing behavior of vertebrates, particularly invasive species, enables the discovery of cues that induce exploratory behavior and can aid in the development of valuable basic and applied biological tools. However, pinpointing behaviors dominantly driven by chemical cues versus other competing environmental cues can be challenging. Ymazes are … Show more

“…A Y-maze was used to run all scent trail tests and has been described elsewhere [ 14 , 25 ]. Briefly, the Y-maze was designed as a fully enclosed testing apparatus fitted with a transparent top for observing tegu behavior in the maze ( Fig 1 ).…”

“…The trail represented in the schematic (A or B) depended on the specific trial type (i.e., for Male-only trials, male skin lipids would be trail A while peanut oil was trail B). Additional aspects of the Y-maze design can be found in Parker, Currylow, et al [ 14 ].…”

“…More specifically, males of both species were chemically feminized with estradiol implants, the dominant female sex steroid hormone known in these snakes, and subsequently became attractive to other males, most notably in field bioassays with wild, reproductive males (Parker and Mason 2012;Parker et al 2018). Development of pheromonal lures for Burmese pythons has been initiated using hormonally manipulated male pythons with estradiol implants following methods of Mason (2012, 2014) in conjunction with radiotelemetry of scout snakes (see Scout Snake section) and Y-maze experiments on scent trailing (Parker and Currylow et al 2021). Preliminary analyses revealed that telemetered, estradiol-implanted males were no different than controls in the number of associated pythons detected, indicating that estradiol manipulation failed to enhance removal efforts at the time of year and doses trialed (A. Currylow, USGS, Written Communication, 4/13/2021).…”

“…However, little is known about much of the Burmese pythons' biology or reproductive phenology in the wild (but see Krysko et al 2012;Smith et al 2015). Several detection and removal strategies have been tested and/or implemented over the years (e.g., Reed et al 2011;Hunter et al 2015;Falk et al 2016;Parker et al 2021), but captures remain low, and population-level information or temporal trends remain limited. However, understanding this species' morphology and reproduction in its entire invasive range which spans southern Florida will provide researchers with a demographic baseline which can aid in the development of new, biologically targeted control tools.…”
