Climate change may lead to decreased flow in
Hawai’i’s freshwater streams
Increase in air temperature, amplified at high
elevations (Giambelluca 2008)
Changes or shifts in annual precipitation
Expansion of strawberry guava
USGS has shown a 10% decrease in stream flow over
the last 30 years (Oki 2003)
How might these changes impact stream biota?
How can we study this impact?
Unique and extreme
gradient in precipitation
Similar landscape and
land cover characteristics
Why focus on shrimp?

Does variation in annual precipitation alter
life history characteristics, abundance and
habitat selection?
Growth rate

Habitat selection
Abundance
1. Production and growth rate

Immediate applications
Better understanding of life history characteristics
Insight into habitat selection of freshwater shrimp
throughout the tropics
Define in-stream flow thresholds
Web-based management tool
Future directions
Use results and climate change projections to
predict distribution and abundance changes
Explore relationships between abundance and
land cover

In streams with less precipitation (i.e. flow):
Growth rate
Secondary production
Gravid females
Individual fecundity
Pool occupancy
Density

Immediate applications
Better understanding of life history characteristics
Insight into habitat selection of freshwater shrimp
throughout the tropics
Define in-stream flow thresholds
Web-based management tool
Future directions
Use results and climate change projections to
predict distribution and abundance changes
Explore relationships between abundance and
land cover

Climate change may lead to decreased flow in
Hawai’i’s freshwater streams
Increase in air temperature, amplified at high
elevations (Giambelluca 2008)
Changes or shifts in annual precipitation
Expansion of strawberry guava
USGS has shown a 10% decrease in stream flow over
the last 30 years (Oki 2003)
How might these changes impact stream biota?
How can we study this impact?
Unique and extreme
gradient in precipitation
Similar landscape and
land cover characteristics
Why focus on shrimp?
Keystone species
Culturally important
Opportunity to gain
knowledge on life history

Does variation in annual precipitation alter
life history characteristics, abundance and
habitat selection?
