The American pika: a model species to study biotic responses to climate change
Philippe HenryNRESi Colloquium SeriesSeptember 27th 2013, UNBC, PG, BC.
American pika biology & climate change
UBC-O/UofC research in BC Coast Mnts
Applications to Management and future directions
Enough time for questions
What is a Pika?
A small relative of rabbits and hares:Order lagomorpha
Two species in North America
Collared pika
- Postglacial re-colonization occurred South to North
- Not North to south as previously thought
- Definitive taxonomybased on:
mtDNA
Vocalizations
Morphometrics
Range retraction- 30% extirpated- 145 m upslope
migration/decade
Drivers of extirpation- Snowpack ~ cold temperature- Summer temperature- Elevation
EvolutionVolume 63, Issue 11, pages 2848-2863, 3 AUG 2009 DOI: 10.1111/j.1558-5646.2009.00803.xhttp://onlinelibrary.wiley.com/doi/10.1111/j.1558-5646.2009.00803.x/full#f5
