Association and reversal learning abilities in a jumping spider
Behavioural Processes, 2014The ability to learn and overwrite learned associations allows animals to respond adaptively to changes in their environment. However, such behavioural plasticity is presumed to be costly and the question arises to which extent animals with restricted neuronal capacity are capable of such flexible behaviour.

Rearing environment affects behaviour of jumping spiders
Animal Behaviour, 2000We tested the effect of rearing conditions on the behaviour of jumping spiders, Phidippus audax. Spiders were assigned randomly to either small or large cages that either were empty or contained a painted dowel. Laboratory-reared spiders were raised from second instar to adult in these environments.

Place avoidance learning and memory in a jumping spider
Animal Cognition, 2016Using a conditioned passive place avoidance paradigm, we investigated the relative importance of three experimental parameters on learning and memory in a salticid, Servaea incana. Spiders encountered an aversive electric shock stimulus paired with one side of a two-sided arena. Our three parameters were the ecological relevance of the visual stimulus,

Spectral sensitivity in jumping spiders (Araneae, Salticidae)
Journal of Comparative Physiology A, 19891. We report here a psychophysical technique for studying the spectral sensitivity of jumping spiders (family Salticidae), based on a newly discovered oculomotor reflex. 2. Our results, obtained from Maevia inclemens (Salticidae), are compatible with electrophysiological findings of retinal cells maximally sensitive in the green and ultraviolet regions

Jumping kinematics in the wandering spider Cupiennius salei
Journal of Comparative Physiology A, 2010Spiders use hemolymph pressure to extend their legs. This mechanism should be challenged when required to rapidly generate forces during jumping, particularly in large spiders. However, effective use of leg muscles could facilitate rapid jumping. To quantify the contributions of different legs and leg joints, we investigated jumping kinematics by high ...

Spatial abilities in jumping spiders.
2020Cognition refers to any state of information processing, including memory, perception, decision-making, and learning. Decision-making, the main component of this thesis, is a cognitive process that allows animals to evaluate their environment so as to avoid less favourable situations.

Extraordinary creatures: jumping spiders
Journal of Experimental BiologyThere are almost 7000 species of jumping spider on the planet, with the family comprising 10–13% of all spiders. Found on all continents except Antarctica, they can live at altitudes of up to 7000 m and are even capable of surviving under water, thanks to hydrophobic hairs that hold a bubble of air around the cuticle.

Orientation by Jumping Spiders in the Absence of Visual Feedback
Journal of Experimental Biology, 1971ABSTRACT Jumping spiders turn to face moving objects. These turns are mediated by the lateral eyes. They can be accomplished accurately whether or not the spider sees the relative movement of the stimulus across the retinae which would normally result from such a turn.
