Biocomplexity of Introduced Avian Disease in
Hawaii: Host Demography Subproject

PIERC Project Leader: Bethany L. Woodworth, Ph.D.

A Southern house mosquito (Culex quinquefasclatus) biting an Apapane(Himatione sanguinea). 65% of Apapane die after receiving a single infective mosquito bite Objectives:

Star  Document effects of avian malaria and pox on native birds in the wild
Star  Determine factors that facilitate evolution of disease resistance and population persistence
Star  Examine effect of climate change on vector-borne diseases


Accomplishments:

Star  Mistnettedand sampled over 12,000 birds at 9 study sites along a 1800-m elevational gradient

Star  Documented the evolution of disease-resistant subpopulations of Hawaii amakihi(Hemignathusvirens) in lowland southeast Hawaii


Feb’06
Significance:

Star  Whether differences across elevational gradient serve as model for effects of climate change on vector-borne diseases

Star  Combined with modeling, can determine weak links in disease transmission that may be targeted for management
