To this end, we have tracked the spontaneous motion of 345 ants walking on a 0.5×0.5 m plane canvas, which was tilted with 5 various inclinations by [Formula: see text] rad ([Formula: see text] data points). At the population scale, support inclination favors dispersal along uphill and downhill directions. An ant's decision making process is modeled using a version of the Boltzmann Walker model, which describes an ant's random walk as a series of straight segments separated by reorientation events, and was extended to take directional influence into account. From the data segmented accordingly ([Formula: see text] segments), this extension allows us to test separately how average speed, segments lengths and reorientation decisions are affected by support inclination and current walking direction of the ant. We found that support inclination had a major effect on average speed, which appeared approximately three times slower on the [Formula: see text] incline. However, we found no effect of the walking direction on speed. Contrastingly, we found that ants tend to walk longer in the same direction when they move uphill or downhill, and also that they preferentially adopt new uphill or downhill headings at turning points. We conclude that ants continuously adapt their decision making about where to go, and how long to persist in the same direction, depending on how they are aligned with the line of maximum declivity gradient. Hence, their behavioral decision process appears to combine klinokinesis with geomenotaxis. The extended Boltzmann Walker model parameterized by these effects gives a fair account of the directional dispersal of ants on inclines.", "link"=>"http://www.mendeley.com/research/ants-make-sense-gravity-boltzmann-walker-analysis-lasius-niger-trajectories-various-inclines", "reader_count"=>40, "reader_count_by_academic_status"=>{"Unspecified"=>1, "Professor > Associate Professor"=>4, "Researcher"=>5, "Student > Doctoral Student"=>2, "Student > Ph.

To this end, we have tracked the spontaneous motion of 345 ants walking on a 0.5×0.5 m plane canvas, which was tilted with 5 various inclinations by rad ( data points). At the population scale, support inclination favors dispersal along uphill and downhill directions. An ant's decision making process is modeled using a version of the <i>Boltzmann Walker</i> model, which describes an ant's random walk as a series of straight segments separated by reorientation events, and was extended to take directional influence into account. From the data segmented accordingly ( segments), this extension allows us to test separately how average speed, segments lengths and reorientation decisions are affected by support inclination and current walking direction of the ant. We found that support inclination had a major effect on average speed, which appeared approximately three times slower on the incline. However, we found no effect of the walking direction on speed. Contrastingly, we found that ants tend to walk longer in the same direction when they move uphill or downhill, and also that they preferentially adopt new uphill or downhill headings at turning points. We conclude that ants continuously adapt their decision making about where to go, and how long to persist in the same direction, depending on how they are aligned with the line of maximum declivity gradient. Hence, their behavioral decision process appears to combine klinokinesis with geomenotaxis. The <i>extended Boltzmann Walker</i> model parameterized by these effects gives a fair account of the directional dispersal of ants on inclines.</p></div>", "links"=>[], "tags"=>["ants", "boltzmann", "walker", "trajectories", "inclines"], "article_id"=>834577, "categories"=>["Biological Sciences"], "users"=>["Anaïs Khuong", "Valentin Lecheval", "Richard Fournier", "Stéphane Blanco", "Sebastian Weitz", "Jean-Jacques Bezian", "Jacques Gautrais"], "doi"=>["https://dx.doi.org/10.1371/journal.pone.0076531.s001", "https://dx.doi.org/10.1371/journal.pone.0076531.s002", "https://dx.doi.org/10.1371/journal.pone.0076531.s003", "https://dx.doi.org/10.1371/journal.pone.0076531.s004", "https://dx.doi.org/10.1371/journal.pone.0076531.s005", "https://dx.doi.org/10.1371/journal.pone.0076531.s006", "https://dx.doi.org/10.1371/journal.pone.0076531.s007", "https://dx.doi.org/10.1371/journal.pone.0076531.s008", "https://dx.doi.org/10.1371/journal.pone.0076531.s009"], "stats"=>{"downloads"=>0, "page_views"=>0, "likes"=>0}, "figshare_url"=>"https://figshare.com/articles/How_Do_Ants_Make_Sense_of_Gravity_A_Boltzmann_Walker_Analysis_of_Lasius_niger_Trajectories_on_Various_Inclines/834577", "title"=>"How Do Ants Make Sense of Gravity?
