The Evolution of the Tiered Principal Retinae of Jumping Spiders (Araneae: Salticidae)A unique sensory structure with an unusual . always poses a challenge to a biologist concerned with the fine-print of Evolution. The principal eyes of Salticid spiders offer just such a challenge. This short Review will identify its nature, summarise the outcome of new findings achieved in the last eight years, and outline some new ones.

Pupil Control in Compound Eyes: More Than One Mechanism in Mothsy of their own (Hamdorf et al., 1986; Land, 1987). We here present evidence for two coexisting mechanisms that control migrations in the pigment cells of some moths. Depending on the experimental design one of these mechanisms may take preference over the other, thus explaining the previous contradictory results.

Yet, we have little understanding of the subcellular and molecular phenomena which control these events.

Analysis of Sensory Spike Trainshion. Biophysical properties underlying the generation of an action potential have been a fundamental problem of membrane physiology; in the last few decades, great strides have been made in this field.
