RESEARCH/MONITORING NEEDS (source(s) of needs)
Monitoring
- Priority
monitoring action – Conduct species-specific surveys (PIF Monitoring
Needs doc)
- High
priority candidate for rapid status assessment (PIF Monitoring Needs
doc)
Habitat
Needs/Ecology/Life History
- Differences
between ISSJ and Western Scrub-Jay in foraging behavior,
territoriality, mating systems, vocalizations, & overall
communication (BNA)
- Studies
of population regulation & ecology in ISSJ including effects of
natural disaster, disease, and ecosystem change (BNA)
Invasives/Exotics/Disease/Parasites/Contaminants
- see
needs under "Habitat Needs/Ecology"
- Use
genetic studies to understand ISSJ's susceptibility to disease (BNA)
Captive
Breeding/Reintroduction
- See
needs under “Genetics/ Taxonomy…”
Demographics
- Long-term
studies of parentage & patterns of reproductive success (BNA).
Genetics/Taxonomy/Systematics
- Determine
how genetic variation in the population could be maintained if
captive-breeding is needed (genetic studies of microsatellite DNA
loci) (BNA)
