The jumping spiders of Mozambique (Araneae: Salticidae)
ZootaxaOnly 26 species of jumping spiders have been recorded from Mozambique to date. The present study is based on materials from four museum collections. Fourteen species are described as new to science: Habrocestum mozambicum sp. nov. (♂ ♀), Hyllus bisulcus sp. nov. (♂), H. ornatus sp. nov. (♂ ♀), H. simplex sp. nov. (♂), H. tetensis sp.

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,

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.

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 ...

Firefly flashing and jumping spider predation
Animal Behaviour, 2012Bioluminescent flashing in fireflies, while primarily a sexual signal, is known to deter some predators while attracting others. We tested whether flashing serves an antipredator function against two species of diurnal, visually hunting jumping spiders, Phidippus princeps and Phidippus audax. To confirm anecdotal reports that fireflies flash during the

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.

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.

The effect of visual priming in jumping spiders.
2018Priming of an animal’s sensory system can influence behaviour. Once an animal has been primed with a stimulus (e.g., the smell of a specific prey), it is then able to find the source of the stimulus (e.g., visually locate the prey) more easily than before.
