We are executing a scheduled maintenance on database services beginning at 9:00 UTC. We expect the maintenance window to be less than 1 hour. Please note that any CI jobs that start before the maintenance window but complete during the window period will fail and may need to be started again. https://gitlab.com/gitlab-com/gl-infra/production/-/issues/4018

Update Ant Encounters - Interaction Networks and Colony Behavior by Deborah Gordon.md

parent 32f2c2a7

- If a patroller encounters another patroller of a different colony, it doesn't signal the direction it traveled when it returns to the nest (assumingly the other patroller signals are used instead)
- This raises the hypothetical, what if each patroller met a neighboring patroller? Would they forage? And if so, in what directions?
## Ant Evolution
- Ant behavior and social structures have been enfluenced by wasps
- Ants coevolved with plants where the high-level relationship is:
- Ants attack herbivores that would eat/hurt the plant
- Ants attack (precisely in fact) neighboring plants that would otherwise consume resources detrimental to their partner
- In return, the ants feed on plant excrement and plants increase their size and distribution, thus providing more excrement
- In some species, fertility isn't a specific ability granted at birth. Environmental conditions and nestmate interactions can render a once sterile female fertile.
- In harvester ants (and it's assumed in many other species), a colony is comprised of at least two lineages, a male of:
1. same lineage -> offspring are female reproductives
2. different lineage - offspring are sterile female workers
- Queens lay eggs of each lineage type in proportion to the # of males in each lineage mated, but growth doesn't occur until colony thresholds (size and/or food supply) are met
- Workers can apparently distinguish between the two egg types and selectively nurture them to control how and when reproductives are released
## Modeling Ant Behavior
- Behavior and ecology are tightly intertwined in modeling a colony
- Behavior as internal influence (interaction network)
- Ecology as external influence (environmental changes)
