Sažetak
We investigated the formation of Artemia franciscana swarms of freshly hatched instar I nauplii
larvae. Nauplii were released into light gradients but then interrupted by light-direction changes,
small obstacles, or long barriers. All experiments were carried out horizontally. Each experiment used
independent replicates. Freshly produced Artemia broods were harvested from independent incubators
thus providing true replicate cohorts of Artemia subjected as replicates to the experimental treatments.
We discovered that Artemia nauplii swarms can: 1. repeatedly react to non-obstructed light gradients
that undergo repeated direction-changes and do so in a consistent way, 2. find their way to a light
source within maze-like arrangements made from small transparent obstacles, 3. move as a swarm
around extended transparent barriers, following a light gradient. This paper focuses on the recognition
of whole-swarm behaviors, the description thereof and the recognition of differences in whole-swarm
movements comparing non-obstructed swarming with swarms encountering obstacles. Investigations
of the within-swarm behaviors of individual Artemia nauplii and their interactions with neighboring
nauplii are in progress, e.g. in order to discover the underlying swarming algorithms and differences
thereof comparing non-obstructed vs. obstructed pathways.
