“…Among arthropods, more and more studies on jumping spiders cognitive abilities are being published (Herberstein, 2011), so much that the inquiries on the structure and functioning of their brain are ever-growing (Menda et al, 2014;Shamble et al, 2016;Steinhoff et al, 2019Steinhoff et al, , 2018Steinhoff et al, , 2017. They have been shown to possess numerical abilities (Cross and Jackson, 2017), behavioural flexibility (Cross and Jackson, 2015) and navigational abilities (Aguilar-Argüello et al, 2018, 2019Jackson, 2016, 2019;Hill, 1979;Hoefler and Jakob, 2006;Peckmezian and Taylor, 2015a;Tarsitano, 2006;Tarsitano and Andrew, 1999;Tarsitano andJackson, 1994, 1997).…”

Risk assessment and the use of novel shortcuts in spatial detouring tasks in jumping spiders

Selection on individuals that incorporate risk to quickly and accurately make a priori navigational assessments may lead to increased spatial ability. Jumping spiders (Araneae: Salticidae) are characterized by their highly acute vision, which mediates many behaviors, including prey capture and navigation. When moving to a specific goal (prey, nest, a potential mate, etc.), salticids rely on visual cues and spatial memory to orient in 3-dimensional space. Salticid spatial ability has been studied in homing and detour tasks, with Portia being considered one of the most skillful genera in terms of spatial ability in the family. Commonly living in complex environments, salticids are likely to encounter a wide variety of routes that could lead to a goal, and, as selection favors individuals that can accurately make assessments, they may be able to assess alternative route distances to select the most efficient route. Here, we tested whether 2 salticid species (Portia fimbriata and Trite planiceps) can discriminate and assess between different available routes by their length, and riskiness to escape from a stressful scenario. Results suggest that while Portia is more likely to choose the easiest and shortest escape routes, Trite is faster in both decision making about which route to take, and to escape. However, some individuals were able to use novel shortcuts instead of the routes expected, with Portia containing a higher proportion of shortcut-takers than Trite. These differences in spatial ability seem to correspond with the environmental complexity inhabited by each species.

Confrontation between predator and prey, driven by the innate survival instincts in both predator and prey, constitute the most significant form of competition in evolution. Yet, understanding how survival skills can benefit from such confrontations remains limited, despite its critical importance for animal survival. We have developed an interactive platform to investigate confrontations between a hungry mouse and an escaping bait. This robotic bait is controlled magnetically through a closed-loop system to continually evade the approaching mouse. Meanwhile, the mouse must capture the escaping bait to receive a food reward. Through analysis of angles, speeds, and other kinematic parameters of both the mouse and the bait, we observed that confrontation experiences can notably enhance mice performance. Compared with novice mice, veteran mice enhanced predation efficiency primarily by optimizing the pursuit phase, significantly reducing time costs, mainly by minimizing pauses in movement. Additionally, experience strengthened the navigation strategies used by mice to better track evading bait. Finally, we validated the impact of empirically induced changes in speed distribution and pursuit methods on predation efficiency through modeling of the pursuit phase. In conclusion, this study reveals that confrontation experience could improve pursuit strategy in mice by altering the speed control and pursuit method, providing new insights into these crucial behavioral interactions in nature.
